i'm getting a weird issue with webrtc in 22.3.11f1. when i try and add it to my project, my app no longer opens on quest 3. i don't get any error in logcat, it just hangs when it is trying to open and the screen stays black. any ideas what i can do to investigate?

[strong panther]

Hi guys i have a problem. In my build when i take the oculus off (therefore it goes in stand by) and then i put it back on, the player's transform is reset (thus the player goes to the initial position and the camera is re-oriented). It might be because the player does not have the character controller? I am using the XR toolkit for my player

[crude frost]

thank you. this looks super helpful

[crude frost]

I'm looking at the mr-example-meta-openxr sample. works on build. yay. Is there a 'must have' checklist somewhere, that says which components you need to enable the AR session?

I'm just going to create a new scene, and 'guess'. And slowly add pieces from the sample until it 'works'. But, would be nice if somewhere there was a 'must have' list to just 'enable' MR on a meta device.

[keen sequoia]

what's your objective?

Hi everyone, I'm currently in the process of releasing a tethered version of a VR application. It is kinda resource intensive and needs a decent pc to run. I was searching up online about determining the pc requirements for a VR software that I can include with the release. Does anyone have any suggestions/advice how to go about this? Much appreciated!

Hi, I have a problem with unity, where I have an inverse kinematic "two bones" constraint to animate vr arms. But the problem is that these arms are not long enough without animating the shoulder too, and there is no constraint that animates 3 bones. So I put a multi rotation constraint on the shoulder to animate it. But the problem is that now the two bones constraint is misaligned and does not take into account the rotation...

As you can see after rotating the shoulder the two bones constraint does not track correctly, it did not take the rotation into account
What can I do?

[rich cedar]

I had the same issue with the shoulder stuff, my solution was to just use the chain ik constraint. It doesnt have a hint option but it works okay

[solemn holly]

is that really ok? without the hint I fear the arm will bend incorrectly

I hoped there was maybe a way to chain several constrains

[strong panther]

I am building my game for Quest 3 and i am finding the audio with a lot of high end frequencies and generally a bit tinny. Is anyone else experiencing this?

[solemn holly]

So, any other people having experienced the same problem or knowing what to do about the two bones constraint?

Or is it impossible to chain constraints on the same branch?

Hello people 🙋‍♂️
Does someone have some news about the EarlyUpdate.XRUpdate taking up huge chunks of ressources ?
I found this https://issuetracker.unity3d.com/issues/xr-sdk-oculus-earlyupdate-dot-xrupdate-spikes-inconsistently?page=3#comments
And this https://forum.unity.com/threads/earlyupdate-xrupdate-taking-about-75-of-main-thread-cpu-time-is-this-normal.920234/
But I haven't seen people mention 2022 lts is still impacted. I got between 9 and 12ms chewed away in my URP project dev builds. I also tried UltimateXR demo scene, it takes around 16ms in editor. Another simple project on 2021 builtin takes 4ms in editor, wich already feels like a lot.
I'm uploading a bug report right now but was wondering if some other people found some workaround or more information on the source of this issue.
I'm on PCVR using Quest 2 & 3 and airlink. Will try with OpenVR and virtual desktop soon.

[manic dock]

I just built a previous Quest 2 project on Quest 3 and nop, no audio issue here. Sounds exactly like on Q2 without any modifications.

Have you checked your import settings for the audio files ?

Here's what I use :

I have another problem with two bones ik though, for the arms it works ok but for the legs they bend in the wrong direction, and when I move the hint on the other side, it rotates them instead of just bending in the direction, twisting my mesh in the process....

[solemn holly]

I tried rotating the bones in blender, but that shi**y hint always place on the wrong side...

[storm ether]

Idk what to do

[lone egret]

Working in Unity XR. I have a wrench with the XR Grab Interactable working. What's the best way to check for it colliding with another object while held? OnCollisionEnter only seems to work once I drop the wrench.

[lone egret]

OK, and setting a Trigger for the points of contact I want to check and then OnTriggerEnter works.

[hardy root]

can i get help when ever i build my game this happens

this is console

[solemn holly]

Anybody about my two bones ik problem? it rotates the bones instead of positionning them correctly when I move the hint to the other side

[strong panther]

I am using fmod. It might be why 😦. I have remix everything adding more low ends frequencies to balance it

Hey is this normal? doing my first VR project and when I rig position value is different from 0 it offsets it and it is not nice to edit/move player around.
First image is pos value is 0,0,0 and second image is 0,200,0.

so is this normal and if not, how can I fix this?

sure, but its probably not going to look good out of the box

[shell pivot]

u worked on fused vr mate?

[tiny niche]

make sure you never move anything inside the root of the rig

[tiny niche]

no

[thorny lynx]

But there has to be for the and right and camera? This never happened to when I was working for pc build only.

[tiny niche]

what? just use the rig prefab they provide and you should be good to go

Can updating the firmware on my Quest 2 break my Unity Project, which was built using an older version of Oculus Integration SDK?

[north path]

Technically possible, yes
Likely to happen, no

[red latch]

Anyone tries to setup the oculus integration sdk with the sample scene setup

Such as virtual furniture demo scene

For quest3

Because I followed all steps from scratch 2 times. The scenes work when starting it from the unity editor using quest link. When I build it, It doesn't work properly

[tiny niche]

well if that broke the project, then the project was already broken and you just didn't know it yet

[tulip cliff]

my friend has a steamvr unity app in overlay mode but cant find any way to cap the fps, unity docs its handled by the sdk but thers nothing in the steamvr sdk for that, any ideas?

[idle sinew]

Is anyone else experiencing them facing the wrong direction when the game starts in the Quest 2 & 3? In Unity test play and when I build an exe file on the PC, I spawn facing the intended direction I placed in the scene. But when I make the apk, install it, and open the app in the Quest 2 & 3, I'm facing a different direction. Even more weird, is that I face a different direction in the Quest 2 than the Quest 3.

[modern ginkgo]

is anyone having issues with the quest 3 controllers not tracking position in the unity editor via quest link?

[gray radish]

with OpenXR does anyone know how to do "mirror"/desktop only HUD or UI?

[idle sinew]

So I got my issue to work by just switching from OpenXR to Oculus if anyone else has been dealing with my issue:

[atomic karma]

how could I go about making a script that switches visibility between two objects on an xr grab interactable when I pull the trigger?

[storm ether]

Does anyone know how to make a ridgid body's gravity only turn on once the player interacts with the object. (XR GRAB INTERACTABLE)

[patent mural]

You don’t actually require the oculus intervention all it is used for mainly is for a store compatible manifest very few use it for anything else, but likely it won’t do anything.

[storm ether]

Yea it wont do anything. Its kinda the reverse for me but I was still on v48 till super recently and I used the newest version so it should work

[buoyant jolt]

I think you already answered your own question 😄 on the press event, toggle between thr objects

[buoyant jolt]

No it's consistent here for me using UnityXR for the vive, Q2 and Q3

[atomic karma]

I just know nothing about scripting lol 😂

[compact gazelle]

Hi guys i am having problems with my headset,this is the thread,can you help me? https://forum.unity.com/threads/ar-not-working-properly.1509026/

[buoyant jolt]

Just as a heads up to anyone, this /\ was duplicate posted in other channels, so getting help elsewhere.

[high bison]

hello. I cant find out, how to solve this problem. Maybe i just overthinking it. I need to create the controller hand models wont go under one collider (plane). Doesnt anyone know how to solve it? I tried many solutions, but one of them changed the actual position of center of the model from the center of the controller. Ah i dont know >.<

[storm ether]

Can anyone tell me how to get started with making it so when you place like for example a rope on a hook it changes prefabs to be like extended and not bundled up. Basically I want it so when it enters a box collider it changes prefabs and uses a socket interaction so it stays in place and the player knows where to put it. XR or VR

[buoyant jolt]

This one is more complex than it seems at first. There are a lot of ways to do this, including rope physics etc. I'd start small and work your way up

[buoyant jolt]

Thats how it has to work, in order to not follow the hand, it needs to stick somewhere. Usually you'll use a joint or something else physics based to try and return it to its default location once it's unblocked, if that makes sense. There are also assets that can do this for you if you need too

[storm ether]

Ok so how do you think I should approach this

I don’t really care about the rope swinging

I am just making it so the player can climb down

[high bison]

oh make sense. I forgot to implement the restore the position. Thank you.

[storm ether]

I see,
I am trying to bone ids from hand tracking in quest 2 using OVR Skeleton script, it is not behaving as expected,

I am trying fetch left hand data and it is giving me body tracking mixed with some left hand data
it worked fine until the last firmware update on my quest

[buoyant jolt]

There are a few ways, I have made my own rope physics things for VR projects in the past. But if you don't care about any of that, just disable the scrunched up mesh, and then create a straight line mesh. I do mine programmatically but you could get by with just a cube. You also could create something with a rig and joints to make it look like a rope. But yeah, I'd just create a thin mesh between two points personally

I have a MeshLineRenderer I made that I should post up on the app store at some point

[storm ether]

Ok

I’ll figure that out

I don’t understand that because I’m like only a few months into unity

[orchid jolt]

If you don’t have 1+ years of experience In Unity outside of VR development then I wouldn’t make a VR game until you have 1+ years of experience in unity

Trust me on this one

[crude frost]

Greetings friends! On a Unity Build, I'm using XR Rig. In editor everything is crystal clear. On quest 2 build, gameobjects close to me are super clear, and gameobjects farther away are not (this makes perfect sense). Is there a way to make it to where gameobjects in the center of my view are clear, regardless of distance in game? And instead make gameobjects less clear as they get further outside the center of my view?

[tiny niche]

Learn the basics first, much faster to iterate on a game made for monitors

[young sedge]

sorry if this is a faq or if i'm looking in the wrong places, but I've connected my headset to my pc and started to run it, but it only runs in the game view and not in my actual headset. in short, playtest doesn't work in my VR :/

[tiny niche]

first, make sure you're able to run other vr games through steam. It's quite posible its your machine that's not configured correctly and the game itself is working fine

if your machine is not the issue, then try the vr template since its set up correctly out of the box

[storm ether]

Why does it go down

[high bison]

i have a problem. I need to calibrate the game. Oculus Quest 2 always change to rotation of view (i know i can refresh it) but i want to do it by software. I have problem, when the user put down the HMD and then put it on again. The calibration resets to start. Doesnt anyone know how to find out, if the user put down the HMD/ put it on again?

[high bison]

oh i got it. 😅 no need a help anymore

[tiny niche]

sounds like you're using the wrong tracking method. it should be stage-scale or whatever they called it

[outer thorn]

Hello, Anyone using Two-stage trigger for the meta quest 3 ?

I'm doing a VR project right now but have an issue with the XR Ray Interactor, I'm using a straight line but when I first hold the button and the ray is on a valid target it will snap the line to it however I don't want it to snap, I can't seem to find a way to disable this, any solutions? Thank you

[solemn holly]

I'm making a full body tracking in VR, but I have a problem with the arms. I am using "ik two bone" for the arms, but when the wrist rotate I always get this 'collapse' at the wrist, and when fully rotated is does a wrap. I tried adding a twist bone, but I still get a collapse effect. I then used corrective shape keys, but now the problem is that when the wrist is fully rotated, i get a 'jump' effect from 180 degree and -180 degree.
How do you usually deal with this kind of problem?

[silver depot]

Anyone into 3d printing? I'm looking for feedback on a controller I'm designing called the XR Pistol: https://youtu.be/XymXIYupF2w

[tiny niche]

i'd be a bit worried that its going to end up very front-heavy and if the printed part breaks, its going to go off at fairly high velocity

using a weighted magazine in the back, and once the weight of the slide is on, it feels similar to a subcompact pistol in weight

[severe salmon]

So my friends, I want to work with the Qest3 depth texture. Is there a mechanism to pass arbitrary data through Virtual Desktop?

[fossil oak]

How could I get input from the vr controllers because InputSystem.FindControl("<XRController>"); finds the XRSimulatedController which is for the XRDeviceSimulator which needs to be turned off when built and doesn't work with VR

and InputHelpers only seems to work with the DeviceBasedController

[willow cloud]

Hmm.. So do you mean your controllers won’t show in game or that you’re trying to receive controller input for scripts? (e.g b = jump, thumbstick = move)

[willow cloud]

dude.
just use cx file explorer

[willow cloud]

AR isn’t VR. That’s a start

[fossil oak]

input for scripts

[willow cloud]

Heres an old example script. It makes the player jump when the B button is pressed, and jumps in the direction of the head. Use parts of this script if you want.

using UnityEngine;

public class Movement : MonoBehaviour
{
    public Rigidbody rb;
    public Transform cameraTransform;
    public float jumpForce = 50f;

    private bool canJump = true;

    private void Start()
    {
        rb = GetComponent<Rigidbody>();
    }

    private void Update()
    {
        if (canJump && Input.GetKeyDown(KeyCode.JoystickButton0))
        {
            Vector3 jumpDirection = cameraTransform.up;
            rb.AddForce(jumpDirection * jumpForce, ForceMode.Impulse);
            canJump = false;
        }
    }

    private void FixedUpdate()
    {
        rb.AddForce(Physics.gravity, ForceMode.Acceleration);
    }

    private void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag("Ground"))
        {
            canJump = true;
        }
    }
}

[fossil oak]

but that says joystickbutton and that uses the pc inputsystem

that works for vr?

[willow cloud]

Oculus Quest 2, yeah

[fossil oak]

alright

[willow cloud]

And that concludes my assistance for you.

[compact gazelle]

I didn’t want to be offensive

It was ironic

Anyway I solved the bug

I am sorry if you felt attacked,I deleted the comment

[willow cloud]

I don’t feel attacked at all, it’s just I’m not allowed to assist people who act like that (btw I said it because this is #🥽┃virtual-reality and you brought up #🤯┃augmented-reality)

[compact gazelle]

Ahhhh,i didnt see this was VR chat,on my view you were like “this idiot knows the difference from AR to VR,it is a start from solving the problem”

Anyway I deleted the comment and solved the problem

[willow cloud]

Yeah, I saw the misconception and I didn’t know if you though ar and vr were the same thing or you were in the wrong channel.

[compact gazelle]

I know it very well,I just posted my problem in this channel cause in the AR channel nobody answered me

[daring drum]

I am trying to make climbing physics like the app lab game Tunnels on oculus quest 2 but i cant seem to get it. Videos tell me to use XR Direct Climb Interactions but i dont have those. Does anyone know how to solve this issue? Or get the XR Direct Climb Interactions????

[high bison]

hello. Im using XR interaction and XR origin (controllers come with script with tracking). But now im straggling about physics. I want to make: hand cant go under table, just stay on the surface) but dont know how to make it with this. Never did physics neither. (Only this, it can go through other objects) i hope anyone can help me with it i tried used colliders, but i cant stop the hands. Controllers are still tracked. Onl i can stop models but it would not looks good (not seeing some movement)

[north path]

Install xr Interaction Toolkit?
And update unity if you're on an old one so it downloads everything to the latest version.
Otherwise you can change the version of XRIT in the package manifest as well

[north path]

On YouTube look for 'vr physics hands unity' and take a look

[daring drum]

What’s the new Unity version?

[north path]

Latest 2022.3 lts is probably best?

[daring drum]

Ok thanks!

@north path should I get 2023? Or 2022

[north path]

As I said 2022.3LTS

2023 might have new features, but also more issues. So I don't recommend it if you aren't super comfortable in Unity yet

[daring drum]

Oh sorry. THANKS!

[daring drum]

@north path how do I get the climbing interactions now?

[north path]

I'm not too sure, you said there was a script, and if it was a Unity guide it most likely was using XR IT

Did you already check other guides?

[daring drum]

Ya the XR Direct Climb interactor comes in the XR Interactions toolkit but I updated Unity and it’s not there

I cant get it in my project tho.

Does anyone know how I can get it in my project? Is there a way to update the XR Interaction Toolkit

[daring drum]

@north path Im sorry for bothering you but again nothing seems to be working. Do you know anything i could do that can possibly make it work?

[north path]

I mostly use VR Interaction Framework, so no. Follow guides and ask specific questions about where you get stuck

[daring drum]

Do you know how to make a script for climbing?

Or any place i can find one?

[north path]

VR Interaction Framework is a VR framework that has it built in

[daring drum]

Where can i find VR Interaction Framework?

[north path]

But just look for "xr interaction toolkit climbing" on YouTube and you get a ton of guides for free

[north path]

Asset store. That's something you can google (;

[daring drum]

All i want is climbinb gut every tutorial says i need the climbing interaction.

Climbing but*

[orchid jolt]

Hey so I’m making a game and I want objects to have weight and good physics. The problem I am running into is that when I use velocity tracking on the XR grab intractable it’s very buggy and jittery and over all and not very good. So I’m wondering if there are settings I need to change or if there is something else I can do to get grabable objects to have weight and good physics. Thanks.

[daring drum]

Can someone fix this code: using UnityEngine;
using UnityEngine.XR.Interaction.Toolkit;

/// <summary>
/// Responsible for getting the velocity container from the controller to the climbing provider so it can be processed.
/// </summary>
public class ClimbAnchor : XRBaseInteractable
{
[SerializeField] private ClimbingProvider climbingProvider;

protected override void Awake()
{
    base.Awake();
    FindClimbingProvider();
}

private void FindClimbingProvider()
{
    if (!climbingProvider)
        climbingProvider = FindObjectOfType<climbingProvider>();
}

protected override void OnSelectEntered(SelectEnterEventArgs args)
{
    base.OnSelectEntered(args);
    TryAdd(args.interactorObject);
}

private void TryAdd(IXRSelectInteractor interactor)
{
    if (interactor.transform.TryGetComponent(out VelocityContainer container))
        climbingProvider.AddProvider(container);
}

protected override void OnSelectExited(SelectExitEventArgs args)
{
    base.OnSelectExited(args);
    TryRemove(args.interactorObject);
}

private void TryRemove(IXRSelectInteractor interactor)
{
    if (interactor.transform.TryGetComponent(out VelocityContainer))
        climbingProvider.RemoveProvider(container);
}

public override bool IsHoverableBy(IXRHoverInteractor interactor)
{
    return base.IsHoverableBy(interactor) && interactor is XRDirectInteractor;
}

public override bool IsSelectableBy(IXRSelectInteractor interactor)
{
    return base.IsSelectableBy(interactor) && interactor is XRDirectInteractor;
}

}

[daring drum]

It says "The name 'container' does not exist. and 'VelocityContainer' is a type but is used as a variable. AND "The type or namespace name 'climbingProvider' could not be found.

Can someone help me fix this?

[high bison]

i tried many of them, but they feel so weird. Rotation is off and feel so unrealistic. It is better to have model as child of controller, but i cant do physics as that >.<

[young sedge]

i hate to be one of those little kids, but i'm making a gorilla tag inspired game and i can't get the rigging right. I put my model into the rig and everything is working fine, except my in-game hands stopped tracking with my controllers. not totally sure what to screenshot so ill give what I can. if anything extra is needed just lmk

[daring drum]

Can someone help me make crouching in vr?

[untold minnow]

what to download for a mobile vr app

[north path]

You can't both have physics and also have the controller exactly where the hand is?
There are different solutions available, but you need to make it to fit your game. I've just used the VR IF physics hands, not with XR IT

[north path]

Not sure where this is, but download Unity via Unity hub and then select the android module and both submodules.
That is for meta/pico/vive

All headsets have setup guides, so look for that

[long fern]

Hello, trying to make a game where you are using tools like wrenches. I want that tool to snap to screws when they are close enough etc. I am using XRI for now, do you know if there is component to do that or maybe I need additional packages?

[untold minnow]

I tried the google cardboard hello app scene in unity, then exported it to android, it works as intended, but not shure why gear icon and cross button not working?

[north path]

That's what you want with UI that is stuck to the headset, right?
Otherwise make the UI world space and don't child it to the camera

[north path]

Probably code it yourself. Detect collision between the wrench and nut and if the angle is proper you can rotate the wrench. There are countless of ways to implement this

Send a screenshot of the canvas gameobject inspector and the hierarchy

[worthy stream]

I got fixed it.

[main quarry]

Hi. I'm trying to build for Pico 4

[high bison]

i dont know, what you meant. I trying to have very precious and real feeling hands in game. When i used their methods. The computing of position and rotation of models were so slow, i see hand has delay.

Thats why i think its better to have models connected as child to controllers. But now i dont know how to create the physics. Only i need to create one physic and it is:"hand model have same behavior as real when i lay them on table"

[north path]

Then modify code and variables. Or make a detection for collision. If no collider is within a radius you set the position directly, if something is close you use a more responsive physics hands.

Stuff needs to change per project. Amd that can be complex. If you want to release your project I would focus on 'good enough' for complex things like this, and then when everything else is finished try again or pay someone to do so

You cannot child the model to the hand, because that's the whole issue with the hand passing through objects haha
That's the thing you need to get away from when going to physics based hands.
You can increase forces/velocity/etc to make the hands more responsive

[north path]

Nice, pico 4 development is actually pretty smooth for me👌

[main quarry]

really??

my Pico developer center doesnt' screen cast

[north path]

Yeah, both with openxr or the pico sdk most of it just worked when following documentation

[main quarry]

i spent 4 hours to find out that my build version was too high for pico4

[high bison]

yea.... Thats a problem 😅 i do understand that. Its little bit frustrating, but im novice in physics and VR. So it gonna take a time to understand that.

[north path]

Owh I just iterate via pico link and then test builds locally.
Haven't needed to use the dev center much

[main quarry]

because the error was: "Error installing"

no clue about

[north path]

That's right in the setup guide in the docs. Android build errors are lacking in general

[main quarry]

I'm using OpenXR

[north path]

Very much understandable
It also took me a while to learn how it works. But there are many different Solutions (which is nice, but also makes it hard to get into)

[main quarry]

have to use steamvr for link

[north path]

Then some pico specific features might not work yeah

[main quarry]

link thorugh their streaming kit doesn't work well

[north path]

Fair, if you have a router close by virtual desktop is also amazing to work with. Better than the pico link app for a lot

[main quarry]

now I can finally have an apk installable. but crash just after launch

maybe the problem was with an oculus dll that i left in the build

this is the logcat when launching

what do you think?

It could still be a version error? i have target=32, min=29

[main quarry]

anyway I like pico4 device more than oculus quest2.
easier to put on and off
the lenses fog up less
the XR boundary seems more stable.
the env is more android like
but for developer I feels lack of support/tools

[north path]

The error says the error originates in qualitymanager, which probably is your script. You gotta manage which plugin is enabled and only call features that are available

[north path]

Put target on auto. I think 29 minimum could work?
Just check the startup guide for pico lmao

[main quarry]

fixed! it was a leftover with oculus auth

now i have my first app standalone in pico4

[north path]

Their dev tools are a bit slower yeah. But it's getting there and they respond to dev emails, which is something meta doesn't really do I feel like

[main quarry]

can u help me to setup the stream to PC of it?

[north path]

Use virtual desktop or get pico link working
But are steamvr, so just check openXR for desktop platform and add quest 2 (and if there pico) controller profiles

[main quarry]

I miss the part with steamvr.
using steamvr is it possible to cast screen while playing standalone games?

[north path]

What do you mean with screen cast while playing standalone?

You test on PC, not standalone

Then to test performance etc you test on standalone

[main quarry]

I want to share the screen while playing standalone

[molten falcon]

I have a problem with my build. Context:

For some reason and without any significant changes my build suddenly started run into some serious issues realted to the OpenXR.so. I have reverted the recent changes but it doesn't seem to help. I have restarted the headsets.

Any advice would be much appreciated:

This is the output from the MetaQustDeveloperHub:

lines that look sus:

Maybe do it via your browser and the regular pico screen share?

[main quarry]

it doesn't work. inside the pico I go in screen cast > browser. and no ip appear

[north path]

Then ask on the pico discord

[north path]

Update to 2022.3.12 and update OpenXR?
Worth a shot.

Also disable HDR in the URP asset.
Make sure you use linear color space (aka make sure the setup guide for quest development is followed)

[scarlet tree]

Okay, So I have an issue with the OpenXR package and it's integration with an XR platform I am not allowed to divulge due to NDA/Developer agreement. It's trying to load Unity Analytics events, which is not supported on said platform. Now, the workaround would be extremely simply, just adding an #if statement to check for the platform in OpenXRAnalytics.cs... But the package is immutable. How do I fix this?

[north path]

Copy the package to your packages folder instead of cache and then unity will use that version

[scarlet tree]

so, copy the com.unity.xr.openxr@1.8.2 folder out of Library/PackageCache and paste it into projectfolder/Packages?

Got it, that worked! Thankyou so much @north path

[verbal sentinel]

Messing a bit with Mixed reality on the MQ3, any idea how to add shadow (on floor and walls) to the objects?

[north path]

I have a free (only directional light) and paid (soft shadows + cascades + additional lights) solution for that on the asset store
https://assetstore.unity.com/publishers/57030

[verbal sentinel]

Thanks. Any tip ob how to create a glow effect (no bloom or postprocessing in passthrough)?

[tiny niche]

if you want glow, you're going to need bloom. but you could sometimes bake the bloom onto geometry that you render

like when there's no occlusion

[pine moat]

hey could someone help me setting up XR

for some reason the simulator is not moving

[idle sinew]

Any one know how to get someone's Meta ID/account name? I want to display their name above their character but I don't know what to write to get that information.

[tiny niche]

usually the issue is that the inputs to the simulator hasn't been activated, or a different device has gotten precedence

if you run it through the debugger, you should be able to see where it takes a wrong turn and which configuration needs to be adjusted

[untold minnow]

I am working on google cardboard VR. It works fine on pc but too jittery on actual mobile and doesn't load water asset and apk size is also very big! (300MB)

any suggestions

?

it says: Bake Ambient Probe' job failed with error code: 2 ('Failed to bake the ambient probe.').

[untold minnow]

and
Failed opening file: '/Users/yuvrajsingh/Library/Caches/com.unity3d.UnityEditor/GiCache/6d/6d0a9f390c85035ff4f9e89f5ea04784.env.tmp'.

[final basin]

After you've initialized the platform and checked entitlements you can call Oculus.Platform.Users.GetLoggedInUser().OnComplete(complete event handler). The completed event handler would be a method with the signature void Method(Message<Platform.Models.User> message), where message.Data is the user data.

message.Data.OculusID will be their username, and you can also get other stuff like their platform ID, profile pic, online/offline status, etc. I think you'll also need to setup the permissions in your project on the oculus dashboard first, so you can access user data

[untold minnow]

anyone?

[bold pasture]

Hi, I have an issue on Quest 3. I will put on the headset and the world is pointing in a particular direction. If I take the headset off and put it on again then the world origin seems to be in the same place, but the direction is now different.

[olive mulch]

hello everyone, I have a question, is it possible to combine OVR Integration for passthrough capabilities while also using the XR Interaction Toolkit?

[edgy relic]

Hi guys, I am working with XR.Hands and humanoid avatar (calibrating with Final IK). The question is how can I use the XR.Hands data to modify fingers position and rotation? I mean I know how to access the pose of each XRHandJoint and then assign it to the transform of the correct finger, but in this way each humanoid avatar may have a different rotation/position and mesh => weird mesh results or even worst finger positioning. Trying to have a general solution, I was looking at the Muscle & Setting tabs of the Avatar Configuration. The idea is to 1. get a human pose 2. change the muscle of the each fingers on updateHands callabck 3. set human pose. Results from this implementation: a bit laggy and I am not understanding how to compute the correct muscle value starting from the pose of the XRHandJoint. Do you have any suggestion/help/open discussion/other approaches? Thank you a lot!!!

[tiny niche]

i don't think you can access the raw data that drives the poses of the 3d mesh

and the xr api just has some high level pose matching that is not going to be enough for your case

[idle sinew]

thanks, I appreciate it!

[edgy relic]

Yes I think you cannot modify the mesh, but you have pos and rot for all the finger joints. From that there should exist a way that allows us to coherently move the fingers of our avatars. As I said you can directly change the pos and/or the rot of the fingers of your humanoid but since most of them have different rigging/structure you should apply a different offset most of the time. This is why I was looking for other approaches such as the muscles/human pose one. But I am open to everything.

[uneven shell]

Hi, the built in unity recorder creates very hard edges when rendering video. please help me. Thank you

[sturdy dirge]

i need help my Gorilla tag fan game lags every 4 seconds

[north path]

Which material/shader?

[uneven shell]

Sorry. It is a Gaussian splatt so it's a point cloud. Anyway. I solved it by using a different scene from another creator

[pine moat]

Hey I have a small problem, I have an XR Origin with a Right Controller that has XR Direct Interactor on it, I also have a XR Ray Interactor to enable teleporting. Now the problem is my trigger button that's used for teleporting will also grab objects. I want to grab objects only using the Grip button, what could be the issue?

@tiny niche

[tiny niche]

that's just how the ray interactor works. you've hit a limit in how xritk is designed to work

you could work around it by making your own teleporter

[pine moat]

wtf so theres nothing that can be done?

nah thats too much haha

[tiny niche]

if that's too much, then yea i don't think vr is for you

[pine moat]

can i at least limit the range somehow at which the object would get grabbed?

its a school project i have time pressure

or its as simple as -> check the position thats getting pointed at, move xr origin to that position if trigger has been pressed?

[tiny niche]

everyone has time constraints, you just gotta pick your battles around them

[nova rock]

Hi! Rendering a Camera to a RenderTexture results in a pitch-black texture on Quest 1 with BIRP. But it works fine on other VR devices and in editor. Any leads on how i can solve this issue?

Edit: found a solution! setting "target eye" to "both" on the camera solves it.

[reef comet]

what is the best way to make a cross compatible game with quest and pc

[buoyant jolt]

We have an abstration framework between the OpenXR and the environment. So on PC, it replaces the XR interactions with mouse interactions, etc.

But yeah, basically, either injecting something between the XR interactions and the objects OR adding a second layer for non-VR is the easiest way.

But we aim for Console - VR & NonVR, VR (Desktop [Steam/Oculus/WMR] & Mobile[Meta/Pico]) , Mobile, Desktop & WebGL (touch/mouse), and then AR (touch with AR). It sounds complicated to type out, but it basically is just 3 interaction layers (VR, AR, controllers and touch) going through a single interaction layer

[north path]

Does it use the same URP asset?
With other vr devices do you mean quest2/pico standalone? Or PCVR?
Already updated Unity?

[nova rock]

hey thanks for trying to help. i found a solution and added it to my previous message

[empty otter]

i can't find the activate interaction event for the new XR Origin controllers. How do i add this back?

[lavish zinc]

Anyone know any package for a VR setup that provides standard third person control but the ability to look around through the visor?

[frigid timber]

I want to make a visualization in VR of a room wherein I can see the air flow at different stationary positions. Can someone help me with it?

[tiny niche]

what do you want it to look like?

[wet vector]

When running VR on an iPhone 15 Pro Max VR and non-VR is displayed at the same time, the non-VR is "on top" of the VR.

I'm 99% sure this isn't a bug with Cardboard, as I've got an older project and a new empty project where this doesn't occur.
I'm at a complete loss as to what can cause this.

Unity version 2021.3.32
Cardboard 1.22.0 (latest)
URP, but changed to built-in and it still happened

[autumn pewter]

Hi, when I want to draw on the page(plane) using virtual pencil(game object) pencil penetrate into the plane. why is it happening?

[lavish zinc]

I'd probably simulate that with different software than import it into Unity

[storm valley]

I decided ill be making a vr game for my school project. When you start creating do you chose for which vr headset you are making it, or do you just make the game and it will run all vr headsets unity supports

If its the first answer, how hard is it to port it to other headsets

[jovial turret]

I'm not a VR developer, more like a VR enthusiast, whom don't have money for a VR set, but

It will depend mostly on the chip inside a portable VR.
I would use quest 2 as my target platform to make sure the game will run smoothly on almost every non deprecated VR.
Standalone VRs won't be an issue though.

Also, you're saying that it's a school project, then why does it even matter?

[buoyant jolt]

We use a modified OpenXR - it'll let you target almost any headset in the market. Some platform specifics like meta files you need to worry about but nothing major

[storm valley]

If i spend time to make a game, i want to put it to use and make some people enjoy it

[buoyant jolt]

But yeah as long as you use VRTK or OpenXR or something cross platform (i.e. not steamvr or oculus specific), you should be able to go to other headsets just fine

[storm valley]

But are there any advantages in developing a game specifically for Oculus Quest 2?

Also if i use VRTK will i be able to publish it on oculus store?

[buoyant jolt]

Yes, if you build it specifically for the Oculus Quest 2, it won't run on the Pico, Vive, WMR, etc. etc.

[buoyant jolt]

Yup, VRTK is one of several wrappers. I'd use OpenXR these days, but VRTK is pretty awesome.

[tiny niche]

probably aren't letting physics handle the pencil movement

[autumn pewter]

what should I need to do? I have rigid body and collideres on my both objects.

[tiny niche]

you need to change how the pencil tracks the controller, so the physics engine can simulate it properly

[autumn pewter]

I am using virtual habs, instead of controlleres

[storm valley]

Well yeah ofc, but as i asked are there advantages? Cuz this doesnt seem like an advantage

[dapper copper]

Hello, everyone. I have a small question regarding how Meta Quest 2 (Android) handles some commands from Unity app and some info will be great.

I try to open a specific webpage using Application. OpenURL().
After I call it, the headset will open Meta Quest Browser, but as a separate window over the app.
What I try to do is to completelly minimize the app and the Meta Quest Browser to remain on screen until I press "Done", which close the browser and returns to my app.

So, because is not made automatically, I tried using AndroidJavaObject for the currentActivity, and after calling activity.Call("moveTaskToBack", true);
Using dev build and script debugging, a issue is raised: AndroidJavaException NoSuchMethodError for the non static function "moveTaskToBack".
As i understood, before the app were completelly minimized, but after newer Oculus updates, the app doesn't minimize conpletelly. It's that true?

[tiny niche]

well if you only have 1 device you target, you'll spend less time testing on multiple devices

but its not really about which device you target, it's about which sdk you decide to use

[storm valley]

Ill only test it on one, on other ones if it works for people it works otherwise idc

[tiny niche]

just make sure you only advertise support for the device you test on then

[storm valley]

I wont advertise and ill just publish it for free, its a school project not some serious game

[tiny niche]

by advertise i meant what you put on the store front. free/paid doesn't really matter and all software you distribute is serious business, cause people are expected to install it on their devices

[dapper copper]

Hello everyone,
I have a small question regarding how Meta Quest 2 (Android) handles some commands from Unity app and some info will be great.

I try to open a specific webpage using Application.OpenURL().
After I call it, the headset will open Meta Quest Browser, but as a separate window over the app.

So, because is not made automatically, I tried using AndroidJavaObject for the currentActivity, and after calling activity.Call("moveTaskToBack", true);
Using a dev build, when call that code, the application closes completely, also with the browser.
As I understood, before, in previous versions, Oculus used to minimize the apps, but after some newer Oculus updates, the app doesn't minimize anymore, it stays active in the foreground. It's that true?

[buoyant jolt]

Did you try it? Then you'll know if it's true. You posted that same question an hour or two ago. I doubt many people have ever wanted to send that specific Java call to the Meta OS. If you want to use undocumented OS functionality to do something, maybe try the Meta Developer Forums... but I haven't ever seen meaningful activity there.

But yeah, if you use an Android specific command - it can and will change after OS patching

[dapper copper]

Thanks @buoyant jolt . I tried it, the application closed, and I don't know to verify if there are any apps in background, I don't even know if it's possible. The question was based on previous version as I understood that at some time was possible to have apps in background, exactly as on Android phone.
Unity suggests this method (https://docs.unity3d.com/2023.3/Documentation/Manual/android-quit.html), but it doesn't give any additional information for using it in VR. (even it's still Android)
I choose to first write here because of the fast replies.

[storm valley]

Im watching a yt tutorial on making a vr game, he chose 3d urp instead of vr, is that because he is on a older version that doesnt have vr, or is it better to use that

[north path]

The templates can be outdated, so I usually start with the 3D urp template as well

[storm valley]

People are saying using URP is a bad idea on quest 2, because it gives bad fps, is that true?

[tiny silo]

It is not true, VR has a high requirement for FPS and that is hard to achieve regardless of what graphics pipeline you use.

[storm valley]

Ok, btw which one do you suggest VR core or URP

[north path]

Not at all, they usually are overlooking some settings.
URP has some performance improvements and downgrades, but overal both are fine and URP had more features

[tiny silo]

URP

[storm valley]

Thank you both

[tiny silo]

But if you are working on VR you need to do what you are doing, its harder by default than "standard" 3D programming

[storm valley]

Do you think ill be able to create a vr game for school project in my free time, in 3 weeks?

[tiny silo]

That depends on the quality you want to achieve and your experience, I suggest you keep it super simple and focus on getting something working

[storm valley]

Probably gonna make a simple aim trainer with a gun and a target, if ill have time ill create more guns and add scores and more info

[tiny silo]

I recommend you stick to only running in the editor and get the VR device working there. Keep the amount of assets small etc.

[storm valley]

Is it that hard to connect my vr glasses to unity?

[tiny silo]

No, it's more that having to make a build and deploy it, means you will have to worry about many other things, whilst just running on the editor you only have to care about functionality.

[storm valley]

I havent even started and its already going wrong

[mental pumice]

Played around with Quest3 and Color Passthrough. Created a prototype with a few experience ideas, hope you like it 🙂
https://www.youtube.com/watch?v=PVoZszQ31MI

[storm valley]

Should i be worried about this?

[jovial turret]

It's just the default layout for the editor is missing.
Happens sometimes, nothing to worry about.

[storm valley]

ah ok ty

[storm valley]

Why does tracking mode origin floor set the view on the ground, is it not supposed to detect oculus height, and use the players real height?

[rapid basin]

i'm far from any expert, but sometimes i've had Unity just refuse to properly track the headset no matter what, and the only thing that fixed it was re-creating the scene in a new project. Not saying that is the cause here, but if you don't find a solution... yeah

[drifting dagger]

Hey so I'm trying to make a unity build for the Vision Pro simulator and am coming across the following error when it tries to boot.
-[MTLDebugRenderCommandEncoder validateCommonDrawErrors:]:5780: failed assertion `Draw Errors Validation Vertex Function(xlatMtlMain): the offset into the buffer VGlobals that is bound at buffer index 0 must be a multiple of 256 but was set to 384.

Any idea what this is?

[buoyant jolt]

I told Apple until they can provide us an actual headset, I'm not touching their SDK. So I'm proud of you for trying :D. That said, it looks like an Apple SDK bug.

It also looks like its a debug command causing the error - so not sure if it is an actual problem though

[drifting dagger]

Unfortunately I'm being prevented from loading my app onto the simulator due to this error. At least... I think it's this error >_>

[buoyant jolt]

You may need to post ont heir forums, I do someone else with similar errors but no responses:
https://developer.apple.com/forums/thread/126143

[scarlet tree]

@drifting dagger , Unless you're trying to make a flatscreen/windowed game, you can't actually really develop for Vision Pro yet. Partial/Full Immersion VR requires the Unity PolySpatial SDK, which is on a "sign up and you might get access to it one day" waiting list.

[drifting dagger]

Ya I know. Just looking for windowed mode on the sim.

[scarlet tree]

are you using any custom shaders? one of the big limiations of VisionOS is that every single shader has to be built through ShaderGraph

and even then, it doesn't support all available ShaderGraph Nodes: https://docs.unity3d.com/Packages/com.unity.polyspatial.visionos@0.1/manual/ShaderGraph.html

Unity PolySpatial XR doesn't support custom ShaderLab shaders on any render pipeline, and if your project uses custom shaders, all of them will have to be authored using Unity's Shader graph. The ParticleSystem component only supports materials with Unity's built-in shaders. Unity's Shader Graph support is an ongoing work in progress for particles.

oh yeah, no particles yet either!

https://docs.unity3d.com/Packages/com.unity.polyspatial.visionos@0.5/manual/SupportedFeatures.html <- No Baked Lighting, No Cameras(?), No Oclcusion, No LoD, no Post Processing, no Skybox rendering, no Fog...

[drifting dagger]

Oh wow. Surely that's like... a work in progress thing >_>

To be clear through I'm not using Polyspacial.

I don't believe a windowed application requires it.

[storm valley]

😭

[rapid basin]

Are you using the Unity XRI toolkit?

[storm valley]

y3ah

[rapid basin]

How complex is your scene? Lots of scripts or fairly fresh?

[storm valley]

just a floor and this

[rapid basin]

ah, okay, then there's no need testing in a fresh scene, i mean, it could be worth a shot trying in a brand new project just to see if it works or not, but probably not the issue

[storm valley]

Could it be the oculus fault not giving its height to unity?

[rapid basin]

Whenever I don't know something or run into an issue I just ask chatGPT, here is what they said about your issue:

The XR Interaction Toolkit (XRI) in Unity is designed to simplify the implementation of XR (Extended Reality) applications, including VR (Virtual Reality) and AR (Augmented Reality). When you're setting up a VR environment, it's important to configure the tracking space correctly so that the virtual environment aligns with the physical space of the user.

The tracking mode origin set to "Floor" in the context of VR typically means that the origin point of the tracking space is at floor level. This is done to align the virtual floor with the physical floor. When using a VR system like Oculus, the height of the player is usually detected during a calibration process where the user sets up their play area and inputs their height, or the system automatically calibrates based on the position of the headset in relation to the floor during setup.

However, there are a few reasons why the view might be set on the ground even when the tracking mode origin is set to "Floor":

Calibration Issues: The player's height may not have been calibrated correctly, or the calibration data might not be used correctly by the application.

Tracking Loss: If the VR system loses track of the floor or the headset, it might reset the origin point to the position of the headset, which could be on the ground if the headset is not being worn.

Software Overrides: The application or the XRI toolkit configuration may override the player's height settings for some reason, possibly due to a misconfiguration or a software bug.

Default Settings: Some VR applications start with a default height if they don't receive or can't find the proper user height data from the VR system.

To resolve this issue, you would typically need to:

-Ensure that the user's height is properly calibrated in the VR system settings.
-Check the application and XRI toolkit configurations to make sure they are set up to use the user's height.
-Investigate any potential software bugs or issues that could be causing the VR system to ignore or override the height data.

no clue if that helps at all lol, but yeah

it's free to use if you want to try it, I find it is much better than waiting for an answer in here or on reddit

you just keep asking questions until it gives you the answer or points you to the correct documentation

[storm valley]

Ill try to fix it when i get home, ty btw

[rapid basin]

if you were using valve index i'd be able to help more but i've never used oculus in Unity

Oh, if nothing works, you could go to the learn.unity course for VR and download the sample room for the first project. See if your oculus works out of the box in that room. If so, it means you just have something unassigned in your project

https://learn.unity.com/tutorial/vr-project-setup?pathwayId=627c12d8edbc2a75333b9185&missionId=62554983edbc2a76a27486cb

I've had issues with headset tracking before on Index that I solved by just combing through that scene and looking at anything different from mine.

[lavish stream]

I use this script to make a prefab follow my right VR controller and if I let go of the button it stops following. that all works but the idea is that the prefab is a ball and if I let go of the controller the ball goes/fly's in the deraction I throw it at.
Could it be the case that its not phisics based movement?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class GrabBall : MonoBehaviour
{
    public GameObject Ball;
    private GameObject spawnedPrefab;
    bool CanSpawn = true;

    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        if(OVRInput.GetDown(OVRInput.Button.SecondaryHandTrigger) && CanSpawn == true)
        {
            Destroy(spawnedPrefab);
            spawnedPrefab = Instantiate(Ball, transform.position, Quaternion.identity);
            CanSpawn = false;
        }
        if (OVRInput.GetUp(OVRInput.Button.SecondaryHandTrigger))
        {
            spawnedPrefab = Instantiate(Ball, transform.position, Quaternion.identity);
            CanSpawn = true;

[wet vector]

Does anyone have any suggestions as to what could cause this ?

[tiny niche]

probably initialized the runtime wrong somehow

[wet vector]

But only on iPhone 15 Pro Max? In this project, using auto init

[wet vector]

I have figured it out, it's caused by MSAA in the URP settings.

[storm valley]

How do i fix this

[buoyant jolt]

It says optional, but if you want to fix it, switch InputSystem.XR.PoseControl to use OpenXR.Input.PoseControl.

[storm valley]

Well yeah i can read i just didnt know how to do that, but i switched to oculus thing anyway so it doesnt matter

[buoyant jolt]

You say that, but it is literally telling you how to fix it.

[rapid basin]

If you're making a project for just oculus, you should be able to get away without using the openxr plugin though

[magic bluff]

Since I haven’t really got a direct answer from googling, can I test the VR project template with a Quest 2 and M2 Mac?

[north path]

You can build to the quest and you can use a VR emulator, but from my experience mac doesn't have a working VR runtime

[magic bluff]

I'd have to transfer the apk to the headset then?

[north path]

Yes, Unity's build and run does that automatically

[magic bluff]

Thx

[frigid timber]

Do you have any suggestions with respect to the softwares?

[storm valley]

Anyone knows how to lock hand position while helding a gun with two hands using XR grab interactible

[storm valley]

Ok nvm i gave up on that

Why tf does this not work

[tiny niche]

probably because you never told the script about the game object acting as a controller

[lofty tangle]

The controller game object, the one that moves as your tracked controller, that will always move with your irl controllers in its tracked space.
If you want hand objects that you can manipulate further. You need separate objects that follow the tracked controller game objects position and you can also make it not follow and do what ever you want via script.

[obsidian marsh]

Hello!
If I build my unity game and push it to applab the update downloads the whole game instead of just update the necessary files.
I'd like to ask if someone could tell me why?
it's a unity quest 2 game

[rapid basin]

If you don't find an answer here, you could see if any of the devs of games like gun raiders or population one are active on social media, and for all you know one would be happy to give some advice. Both games have what you're after

incase you decide to un-give up on it

[shrewd sentinel]

Hi! I have been thinking about a way of optimizing my scene by making some windows having a "fake" pre-rendered scene already made (instead of an actual window and 3D geometry). Possibly by using a stereoscopic image. Has anyone tried this before or think it'd be passible as real? I know the illusion would probably break for objects near the window, but the scene will be viewing a city so everything is a bit distant

[tiny niche]

shouldn't be a problem, skyboxes are pretty much just that anyways

just make sure the window itself is real geometry

[storm valley]

I dont hear sound while playing my game on oculus quest 2, anyone knows whats wrong?

I know its 2 years later but did you find a solution to this?

ok nvm it just fixed itself

[warm whale]

I don’t even remember bro that stuff was so confusing and chaotic

[storm valley]

Can i make XR grab interactable only activate with one controller and not the other

[tiny niche]

not unless you remove the interactor from the other controller

or modify the toolkit to allow it

[storm valley]

what about only working with two hands

[tiny niche]

there's a limited set of multi-grab functionality in the latest version you can use

haven't looked into it all that much, since the rest of the toolkit is very limited in what's possible without editing the source and the naming convention makes no sense at all

[rapid basin]

Could you not assign a tag to objects that are meant to only be held in one hand, and then use a script to block objects of that tag from being interacted with via the hand you don't want?

Interaction layer, not tag*

so if you have a gun that is only meant to be held in the right hand, you could create a RighhtHandInteractables layer for it

[storm valley]

I want guns that are supposed to be held with both arms to be locked so that the left hand is in the front and right in the back

[rapid basin]

I saw that yesterday, but you said you'd given up on that for now. Trying again? It's definitely possible, it's just a matter of how to do it

Usually whenever I have something I want to do, but no idea how to do it, I just ask chatGPT to help me learn, here is what they said for your issue:

basically just create a secondary grab point for the barrel of the gun and then handle the rest with scripts, but remember once you implement dual-hand guns, you have to create a whole second aiming/gun rotation system (since the gun now rotates different as it's held by both hands)

[tiny niche]

that just means the gun is oriented along the delta between the right and left hand. then you need to decouple the hand visuals from the tracking, so they align with the gun correctly

Hello all, im working on a unity application. I need to save log files, which are currently being written to Persistent Data Path, that part is fine. What im struggling with is how to then access those files, I cant seem to find out how to do it. Windows 10 computer with an Oculus Quest Pro. Thanks

[pine bison]

https://docs.unity3d.com/ScriptReference/Application-persistentDataPath.html

When grabbing files here you can

1. Do it via adb
2. Do it via the regular file browser
3. Use Meta Developer Hub

[grave pewter]

Trouble was the headset wasnt showing up in file explorer, and the file browser in the developer tools didnt have a full file access, only screenshots and programs.

Hello, I'm currently trying to figure out a way to check if an object has been placed in the XRSocketInteractor, what I am trying to achieve is a way to set the parent of the object that has been placed in the Socket to be the object that has the XRSocketInteractor as a child

[pulsar marlin]

Any update on this?

[lavish stream]

Hey i'm in a bit of a struggle using passthrough on my quest 3
If I use the same settings as the image shown and my centre camera from the OVRCameraRig to sollid color (0, 0, 0, 0) it shows pitch black in runtime.
I can change the value's in the script but I cant make it that it shows passthrough and the objects are not transparent. becouse the always are if the background is not black.

[pulsar marlin]

Use OnSelectEntered for future reference. Solved.

[frigid timber]

I have an .fbx file extension, I want to enhance it's experience and import it into VR. Can anyone guide me with this?

[lavish stream]

With enhance you mean just use/view the fbx model in runtime?
If so you can just import the fbx in your unity project and place it in the scene as if its a normal 3D project

[frigid timber]

Thank you @lavish stream for the response. By enhance I mean, the .fbx file contains air flows in five sided room. I need to visualzie a room and put that/see that air flows into it.

[frigid timber]

Like this, which are air flows.

[tiny niche]

you could render that as a wireframe probably

[frigid timber]

Ok, where can I start from?

[tiny niche]

the vr template

[frigid timber]

Thank you, can you share more about the precedure? So, that it can be more clear!

[tiny niche]

press new project in the launcher and scroll until you see something named vr

then drag&drop the fbx into the unity window and make a shader that does what you want

[frigid timber]

Alright. I started and will update soon as I see the results and proceed further.

[orchid jolt]

Hey so I’m making a game and I want objects to have weight and good physics. The problem I am running into is that when I use velocity tracking on the XR grab intractable it’s very buggy and jittery and over all and not very good. So I’m wondering if there are settings I need to change or if there is something else I can do to get grabbable objects to have weight and good physics. Thanks.

[frigid timber]

Hey @tiny niche , so you want me to do something like this? https://youtu.be/ekPzTwSEmKg?si=4Y_3qkMh2wfO0l7x

[tiny niche]

yea use shader graph to make a shader and material rendering the wireframe for the airflow mesh you import

[frigid timber]

Thank you. Alright. will update with the progress.

[storm valley]

My gun shoots bullets sideways, anyone knows how to rotate them, as rotating the prefab does nothing

[rapid basin]

the bullets are instantiated upon firing I assume? Try using the script to tweak the instantiation position and rotation instead of modifying the prefab directly

[storm valley]

But i have multiple guns, and their bullets are rotated differently

[rapid basin]

I haven no idea what would cause that, but a script for each gun could be required to fix it

try it for one gun and see how it works out

[frigid timber]

Hey @tiny niche , Can we connect over video or voice call, so that I can get the proper perspective of your advice? So far, I'm only just able to import the .fbx file into the UNITY and from there I'm not able to shader and render the wireframe.

[lavish stream]

No one knows?

[north path]

Try the forums if no one replies :p

[rapid basin]

Change 0,0,0,0 to 0,0,0,1 and see what happens

[lavish stream]

that changes nothing

[lavish stream]

What forms can help me then?

[north path]

Unity forums and/or meta forums

[lavish stream]

The problem is is that I get a black screen when I use post processing or HDR rendering on the camera's if I dissable it it works fine.
I dont know if its possible to still get it to work with post processing on

[obsidian marsh]

hello!

If I build my unity game and push it to applab the update downloads the whole game instead of just update the necessary files. I'd like to ask if someone could tell me why?

[rapid basin]

is passthrough's layer rendered after all postprocessing? you could try to exempt passthrough from post processing + HDR, if you don't specifically need them to affect passthrough, but are causing issues anyway

[fringe bluff]

Does anyone know why when i use the teleportation provider, it puts me in the ground?

[fringe bluff]

I think it would also help to know its's teleportation on terrain

[frigid timber]

Hey @tiny niche , is there any tutorial you can suggest to get the visualization for the air flows?

[hushed shadow]

Hi everyone
I am trying to implement Hand tracking to my game with open XR and with controllers everything is fine but when I try out the hand tracking I see 2 sets of hands on my oculus quest
in the editor I dont see the 2 sets of hand but in my headset I can see 2 sets of hand with an offset one that move when I move my hand and the other that is correctly displayed
the other is some sort of ghost that does not interact

i was testing the demo hand scene in the XR interaction tool kit

its like if the left and right hand are not displayed on the correct eyes (inverted)

actually its just the right eye... any solution?

[north path]

I'm guessing it just replaces the apk and installs it fully.
Not sure why meta doesn't do some kind of incremental updates

[brittle hedge]

Hello, I'm new here. I attempted to create an empty iOS app using Unity version 2022.3.12. Subsequently, I opened it in Xcode 15 beta 3, built it, and ran it on the Apple VisionOS beta 3 simulator. The build was successful, and the app appeared on the simulator's home screen. However, I encountered an issue where the app couldn't launch. After clicking the icon, it crashed (I believe) and returned to the home screen. Any insights on why this might have happened?

[edgy relic]

I am playing with XR Hands (1.3.0) and Quest 2 and the hand visualizer scene: I am getting OpenXR hand provider failed to initialize - no data will be tracked or surfaced! Anyone have ever faced this error?
p.s. if I build the scene it works, but in play mode it gives me this error.

[frigid timber]

Can anyone share or show me how to make a room in Unity based on ** revit** file I have?

[clever zinc]

export revit file to obj/fbx and import it into unity?

[midnight delta]

What would be the best way to track hand movements to do certain actions? Like draw a circle for a spell of some kind or something?

I could save a bunch of points and loop through checking distance but that hardly seems the best way

Maybe an image using pixel colour mapped from a real position to tell if it’s in the bounds of the action?

[lofty tangle]

Something like that exists already

how bad do materials perform for vr

edpecially stansmdalone

because im worried having ao and normal and metallness on a material will be way less performant than just a basemap

is that so or is it no difference

[oblique panther]

Has anyone used the ForcdSelect method in the Oculus SDK (now Meta XR SDK).

[buoyant jolt]

Hey Mike!! Not in a long time 😦 we moved over to the XRI. But from what I remember, I had to trick it with hovering, but ended up just modifying the Meta sdk (definitely not recommended). We've had to modify the XRI too to fix some of the OpenXR hand tracking stuff...

Offhand I remember it was just easier to override the hover state when force selecting. I remember it took me longer than it should have to resolve:D

[buoyant jolt]

Not bad at all. There is URP as an option but the performance gains debatable.

Your better off focusing on using texture atlases and static meshes. Your draw calls will usually be an issue long before the PBR IMHO.

[storm ether]

im using urp

[storm ether]

texture atlases?

what are those

and with static meshes you just mean meshes with static on right

sorry im stupid lol

[edgy relic]

https://forum.unity.com/threads/xr-hands-not-showing-hands-with-quest-2-with-link-cable.1517167/ Anyone is able to give some help about this problem with hand tracking?

[rapid basin]

do you prefer the XRI kit to Meta? I have only ever used the XRI kit, how do they compare?

[buoyant jolt]

I don't like platform specific toolkits, we support a lot of headsets, so we can't usually use like a meta only framework very often. We did for a while through the VRTK, but OpenXR finally got where we needed it 🙂

We have our own version of the XRI now that we use though 🙂

[rapid basin]

thanks for the reply, I had always planned to try Meta's kit but every time I look it seems less relevent (since everyone just does OpenXR-based kits these days)

[rapid basin]

I want to customize it one day, but i'm not there yet

I got to ask the Among Us VR devs what they used to build the game, looks like they did the same, custom XRI/OpenXR kit

[buoyant jolt]

Yeah XRI is a great starting point, but not quite production ready in terms of looking and feeling good. So we needed to redo a lot of things like the teleporters, and getting things like better more expandable interaction systems, highlighting and outlines stuff. But we also tied it into our web, desktop, mobile and AR to make it easier on the dev team. Probably what I rewrote the most was their hands integration because it's kind of barely usable in the openxr as it is today for real projects.

But it was absolutely worth the effort, to be able to swap between headsets and platforms without any code changes.

[short nova]

@buoyant jolt , that is really excellent feedback. Ultimately we would like XRI to be production ready out of the box, so any details would be greatly appreciated so we can take some action items and improve the package. I will say that we are actively working on the visual and auditory feedback system (highlighting/outlining/etc), plus we have a big update for hands coming soon, but I am curious what improvements you had to make to the core interaction system as well as the teleporter.

[buoyant jolt]

I'd love to, but I don't have time to share the feedback, sorry! But I appreciate the opportunity.

[ancient mist]

How can I get my character to not have it's hands on the floor in VR?

[lofty tangle]

I stopped using the toolkit a while ago cause I ran into issues with things like forcing deselect on destroyed objects or using other inputs for extra actions on a held object

[livid pier]

I am seeing this now sometimes, not always. Seems like if I quit and restart it doesn't throw this error till I've built a few times.

[modern ginkgo]

does anyone know if quest 3 supports multimodal input without the quest pro controllers?

[tiny niche]

what do you mean by "multimodal"?

[storm valley]

Why is the bullet rotated sideways when it comes out of the gun?

The bullet doesnt even spawn at the end of the barrel anymore :(

[untold minnow]

https://paste.ofcode.org/5W5tQW73vJeFhcBuZ5nE4R

i'm using googlecardboardVR tools and I want to make player move voluntarily. For that I tagged 2 objects with walk and sprint resp. I want that when i point the rectile towards them , i move otherwise don't. In this script, its casting a ray in the game environment, if it colides with the tagged objects, it moves.
As there are no triggers in cardboard vr, so i thought this would work. but not working!

[short nova]

What is the orientation of your spawn point? Is that what is in the image at the tip of the barrel? Have you tried commenting out your dispersion math and made sure it shoots straight without adding that variance?

[storm valley]

Yeah its the tip of the barrel

Will try that

[short nova]

I also see a slight code error... you are setting the spawnedBullet.transform.rotation = transform.rotation, not spawnPoint.rotation.

You also might set the shotDirection to point in the forward direction of the spawnedBullet.transform for consistency. Then you ensure your prefab/model forward direction is aligned as you would expect it.

[storm valley]

This fixed the rotation but they still shoot like 2 meters away from the barrel

[short nova]

sideways or forward? Are there any accidental game object offsets in the hierarchy of your bullet prefab?

[storm valley]

Forward

[storm valley]

Bullet is only made from one part if thats what you mean

[short nova]

Yeah, just checking, can't count the number of times I've saved a prefab with an offset on the child object on accident.

Can you determine the z-position where the bullet appears to be spawning? Is it equivalent to the shotSpeed?

[crisp idol]

Does anybody know how to make a ball movement system for VR so whenever you kick it it actually acts like a ball?

[untold minnow]

kindly help 🛐

[crisp idol]

please help i have been strugling with this for days :/

[storm valley]

How can i determine that

[short nova]

Are you aimed at specific game objects or some UI objects? You may need to add the proper Graphics Raycaster or Physics Raycaster component to get this to return any results.

[short nova]

If you don't set a velocity when it spawn and turn off gravity on the rigid body, you should be able to pause the editor and check the inspector values for the barrel tip vs the bullet, but with velocity at 0, I would expect it to spawn where you intended it to.

If it's still offset in the forward direction, that would require deeper diving. Are you setting the velocity in the Update function or FixedUpdate?

[storm valley]

ok i made velocity 0 and it works

now why does that happen

[short nova]

How are you tracking the foot? That aside, I would make sure you are updating the foot position with a TrackedPoseDriver that is set to FixedUpdates and has a collider on it. For the ball, I would make sure the ball has a rigidbody component with some heavier mass set (you'll need to play with it to get it right), plus also add a physics material and tweak the values. There may be some examples floating around out there for proper soccerball/football physics materials. That's where I would start as a proof-of-concept. Put in a few walls with colliders to make sure the ball bounces off them in an expected way.

[short nova]

My guess is that the velocity is getting updated on the FixedUpdate loop (out of band of the Update loop) so it is applying your shotspeed along the forward vector of the bullet. If you crank your shot speed down, you will probably see the offset start a lot closer.

[storm valley]

Yeah it did get closer

[crisp idol]

Hey, I use Gorilla Locomotion and tried some scripts that I found because my was not working. I am kinda new to this thing so i also tried to ask GPT but all the stuff wasnt working

I used rigidbody but only with normal mass (1) do i have to set it higher?

[storm valley]

Yeah i dont get this at all

[short nova]

Are you instantiating the prefab in the Update function?

[storm valley]

yeah

[crisp idol]

Also i tried to find some on youtube on google but there is none sadly

[short nova]

You might try using the AddForce method on the rigid body instead. It may produce more predictable results: https://docs.unity3d.com/ScriptReference/Rigidbody.AddForce.html

[storm valley]

Kk will try this

ty

[short nova]

How is it currently behaving when you kick the ball? You also might try using your hands with a direct TrackedPoseDriver instead of the GorillaLocomotion code to see if you can 'punch' the ball and get it to move how you want it to.

[crisp idol]

It just doesnt

[short nova]

If that doesn't get it working how you want, I might try asking in the physics channel. They have more physics expertise than I do and have probably seen this question a few times over the years: https://discord.com/channels/489222168727519232/497874196274348032

[crisp idol]

Do i need a script or do i need to do it somehow else?

[short nova]

Can you send a couple of screenshots of your setup of the 'foot' game object and the 'ball' game object so we can see how your rig is setup?

[crisp idol]

Sure

this is the ball and its script (yes the script is chatgpt because i couldnt figure it out)

the only thing i have added to the player is rigidbody (not to the hands but the player)

Like i said i am kinda new i have made another game using gorilla locomotion which is why i thought this would be easier and that is my whole game point "soccer but gorilla locomotion"

this is what the player and the ball looks like just incase you need to see that

the player is default with gorilla locomotion (this pack that i added)

[crisp idol]

Yea nothing I try is working.. Maybe i need to do something on the hands?

[modern ginkgo]

https://developer.oculus.com/experimental/multimodal/

[tiny niche]

wow, that's a strange term for the feature

but the definition is also using hands+controllers, so if you don't use the controllers then you can't have the feature

unless you meant using quest2 controllers, but i don't think the quest3 supports them

[modern ginkgo]

i may have worded my question poorly - my question is does the quest 3 support simultaneously tracking quest 3 controllers and hands

there are some random blog posts online to suggest it does but the docs don't mention it and i couldn't get it working

[tiny niche]

well the link you sent explicitly says that it does, but its an experimental feature

[modern ginkgo]

it doesn't mention quest 3, only quest 2 paired with quest pro controllers or quest pro paired with quest pro controllers

[short nova]

The feet should have individual colliders you want to represent feet/hands. They probably don't need rigid body components added separately.

[short nova]

If you click on the ball, does it move the ball? If not, you might try adding some logging to make sure the click and all that are working correctly.

[tiny niche]

i think you can presume that the quest3 is going to work the same in this regard and potentially even have the feature gotten moved from experimental to supported

[untold minnow]

this not working

i want to move the object in the direction camera is looking when i click the screen

I posted it there and still got no replies, while I also didnt have any luck fixing my problem, what do you suggest i do now?

[rapid basin]

honestly, I have found ChatGPT to be extremely helpful when to comes to solving problems that others can't help you with in Unity

Tell it your desired outcome, tell it your current results, be as detailed as possible, and then copy+paste your script so that it can analyze it. It will, 9 times out of 10, give you advice that leads to you fixing your problem. GPT 3.5 is free to use, however I have no idea if it will be as useful as the paid-version that is GPT4

it's a great tool for solving problems when you've given up on all alternatives, but dangerous to rely on too much.

I used it to teach myself how to use the XRI kit back in feb, and it was a lifesaver for solving problems that not many people had encountered before

[storm valley]

I tried it and its completly useless, it just returns my code witout any change at all and says it fixed it

[rapid basin]

oh, do not use GPT 3.5 for code, it is garbage

but use it for problem solving within Unity, i.e pointing out where your issue could be coming from, suggesting things you may have overlooked, etc.

but for code, yeah, only GPT 4 is decent with its code, and even then you need to be very clear with what you want

[storm valley]

I think i already know what the issue is i just dont know how to fix it

[storm valley]

Yeah i dont have money for that

[rapid basin]

They closed subscriptions anyway due to demand, but if you continue to find no answers to your problem, shoot me a dm and I can run your problem through GPT4 and see if it helps you.

Again, just as a last resort, it's always ideal to find human help of course

[storm valley]

kk ty, will dm you later if i dont fix it

That required mesh deformation or pre-made animations

Mesh deformation is something I've done quite a bit, and it's a very complex topic to tackle. Especially when you also need good performance.
I suggest to do this using animations, which trigger or lerp when you start cutting. Blendshapes also might be a good fit for this

I have a photoscanned environment in unity it is all in one mesh/fbx. I want to be able to set up box colliders around these photoscanned items which can be pressed in VR. When pressed it would show/hide text. How can I achieve that?

[short nova]

Are the scanned items created live or just brought into Unity to work with? If you are bringing them in as individual models, just put a box collider on them. If you are using the XR Interaction Toolkit, you can add an XR Interactable component to the object and tie into the Hover Entered and Hover Exited Interactable Events. That can be used to show/hide some UI elements in your scene.

[fallow kelp]

The environment is a room that was scanned from RealityCapture and moved over to Unity so it is just one big model

[fallow kelp]

What if I wanted to make something that was like a button? For example, when I hover and trigger on a object, it shows/hides text

[pseudo plume]

i havent used unity, or ever made a game, but i know some programming. anyways, i wanted to try setting up a vr game
for some reason every time i get into the game i end up with some veriety of a portion of my body inside the floor

instead of looking like that

i tested with mixed reality portal & steamvr, any ideas?

[ionic thistle]

There is a option for tracking origin mode set it as floor

[pseudo plume]

it is

i am thinking it has smth to do with the character controller

[ionic thistle]

Try to debug it by disabling character controller script and just check whether the tracking origin mode is working properly

[pseudo plume]

ok

yah the lower half of my body is very much still in the floor

sooo ig its not character controller

oh also whenever i unplug the headset unity crashes bc of some gpu usage related error

other settings if that helps

[ionic thistle]

If you can't figure out a way then set the tracking origin mode as device and set its height as 1.6 also set the same value in y position of camera offset gameobject inside the rig.

[pseudo plume]

that way is hard to get the hight right...

but if i have tracking origin start as device

than change it back to floor while the games running

it ends up correct

thats not a fix but maybe that means smth

Hi! What is the established solution for reflections in VR that don’t break depth? Is there something that can at least push back the reflection map so that it’s deeper in the screen?

[tired viper]

anyone interested in working on a paid virtual reality project. DM me please

[buoyant jolt]

Not the place for that.

[buoyant jolt]

I believe there is a gitlab repo for that already on the web for Unity. You'll need to Google around for it.

[buoyant jolt]

For soft (I.e. water based) reflections, I ended up making my own shader. It's a bit if a lazy hack though.

I haven't looked but there are probably some VR friendly asset packs with better reflection support.

You can also trick it, in some cases, with cameras. I have done this for mirrors before where it has a hidden camera looking at the player to fake a real-time mirror without doing a real-time reflection probe. I'd be interested in how it works out for you. This really only applies to real time though, baked in reflections work fine for me in BiRP

[cloud wagon]

Thanks for your response. It’s interesting that you say ibrp normal baked reflexión maps work for you, as that is not what I’m seeing in my project - the reflections are kind of at 0 screen depth so often appear closer than the object they are reflecting on

[buoyant jolt]

Yeah that's odd... we have a lot of baked reflections in our education projects (quest & pico) and I've never noticed the baked reflections being off. But maybe I haven't looked close enough at them ?

[mystic kraken]

Anyone able to help with controller position and rotation offsets?

Its a joke this was meant to be a simple 10 minute demonstration for someone and I couldn't get the controllers in the right position. Its been 2 days

First I tried a sphere and its rotation was completely off so I've switched to Meta's quest touch controllers. The official models

Using those the rotation is right but now the position is offset

Its an OpenXR specific issue I tried exactly what the one forum post everyone points to said and had no luck

Unity said this was fixed in newer SteamVR versions and yet it isn't

Don't really know what details to provide as I'm not knowledgable on the new input system 'nor XR

[short nova]

@mystic kraken , if you are using OpenXR, you might try using the pointerPosition vs the devicePosition to see if that helps with the z-offset. This is due to the center of the models being misaligned with where the center of tracking comes from OpenXR (and OpenXR has different poses for different purposes: https://registry.khronos.org/OpenXR/specs/1.0/html/xrspec.html#semantic-path-standard-pose-identifiers). I would suggest picking pointer (aim) or device (grip) and align the model to match the diagram in the link. We do this with the generic controller in the package samples in the XR Interaction Toolkit, so you might use one of those as reference.

[summer locust]

If someone could point me in the right direction resource wise for the following, I'd really appreciate it:
I'm about to start a project that needs to be able to log arm and hand tracking, be it poses or movement, but I'm kind of stuck on where to begin since I need to verify if it was done correctly too, is this possible via XR alone? and just for reference, this is for the index controllers, not quest or leap tracking.
All I've been able to find are resources on poses and how to work with them a bit

[buoyant jolt]

Well, index uses controllers, so you can't really do hand or arm tracking, it would just be guessing from the butt of the controllers and angles

It's also kind of old tech, we have all our medical clients/ hospitals patients etc on wireless headsets - IMHO of course

That's kind of enough, it doesn't have to be perfect.

The purpose of what I'm trying to create is more personal, it's for teaching vr's version of sign language for a friend, doing it, so rather than perfect tracking it's more so the motion and certain poses.

More so doing it to learn, even if it is a little bit of an obsolete project

I take it there isn't a good way for logging the finger positions with the indexes knuckle controllers then, since it's more of a estimated finger tracking?

[rapid basin]

https://store.steampowered.com/news/app/740250/view/2873815014878625258

finger tracking is possible with Index but, a quest 3 would be more ideal for such a project if you can afford one for it

even a quest 2 would be okay, although hand/finger tracking will drain the battery within no time

[summer locust]

I see, I might have to look into getting either of them then. Thanks! I didn't even consider using the headsets camera on the index because of how bad it was

[rapid basin]

yeah, as great as the index still is in many ways, it's also got plenty of things like the camera that... aren't as great, and were just thrown in just incase modders made use of it

[patent valley]

Ok thanks I’ll try that later

[frigid timber]

Hello everyone, I want to put the airflows into the cubical room and later visualize it in VR. I'm attaching the image for your reference. It's urgent. So can anyone help me with this?

[buoyant jolt]

I'd need more specifics including why this needs to be rushed, and how the data for the airflow is captured. But my immediate suggestion is the vfx graph. We've done some incredible demonstrations in VR with it in short order.

[frigid timber]

Thank you. I have to present it at the board meeting of my university's department. The airflow is captured from CFD using AutoDesk.

[brazen tundra]

Hi all. One of my customers said that when he tried to open my game it was all black, which is strange because my game works inside the editor, when I tested the built version I noticed that the screen was indeed black however I could still hear the background sound. What could be the issue?

[buoyant jolt]

Broken vulcan support, bad manifest, urp issue, shader issue for mobile, overlap causing culling - I've seen that last one a lot lately. Etc.

[brazen tundra]

Thanks for the reply Iloyd! Is this something that will appear in the log?

[buoyant jolt]

Quite a few errors in that log,

The referenced script on this Behaviour (Game Object 'Head_Low') is missing!
The referenced script on this Behaviour (Game Object 'Head_Low') is missing!
The referenced script on this Behaviour (Game Object 'MagazinePouch') is missing!
The referenced script on this Behaviour (Game Object 'Head_Low') is missing!```

There are other OpenXR errors in there, a bunch of things marked as DontDestroyOnLoad that aren't base level objects and errors about the NavMesh not being baked.

With that said, it looks like it's being used on SteamVR, not Oculus, so that may rule out Vulcan

[brazen tundra]

Thank you, I'll take a look

[buoyant jolt]

Chances are the error messages around SteamVR and OpenXR are the problem, but it's hard to be sure.

[rapid basin]

[dapper copper]

Hello to everyone :),

Does anyone know to launch the Meta Browser in an VR app for Oculus Meta Quest 2? (using AndroidJavaObject)

I made the following code, but for some reasons it only shows me that 3 points loading and returns immediatelly to initial VR app.

[buoyant jolt]

What does the console log tell you? It will say if the intent didn't exist etc

You can also do it the non-intent way with Application.OpenURL.

[dapper copper]

I don't encounter any logs or issues in the console. @buoyant jolt
The thing with Application.OpenURL() is that opens the app over the current app.
What I actually want is to minimize the Unity app and trigger an launch of the Meta Browser. Any ideas?

[dapper copper]

After some research, using Unity 2021.3.26f1 and Open XR, looks that will not be possible, as I couldn't simply minimize the app (the app is closing completelly everytime).

I used unityActivity.Call<bool>("moveTaskToBack", true), which I understand that should minimize the app for Android, but on Oculus Quest 2 looks that it's actually closing the application completelly.

[frigid timber]

Thank you @buoyant jolt , for sharing . I will look into this and see how it goes.

[buoyant jolt]

Yeah sorry for the late reply. I saw someone else going through that last week with the same problem

[fiery vale]

Is there any way to open the native Meta Quest 2 / 3 image gallery? I think it shouldn't matter whether it's AR or VR. I would like to be able to open the image gallery, select a picture, and fetch its path somehow, so I can then set it as a sprite for an image in the 3D world. Does anyone know any specific plugins?

[buoyant jolt]

It sounds like what you really want is an image selector. If you launch the gallery app it won't return to you after you close it.

There are lots of file selector plugins for Android that should work, but you could also draft one yourself. You'll probably need to request folder permissions and be prepared that a user may reject them however

https://communityforums.atmeta.com/t5/Unity-VR-Development/What-s-the-working-file-browser-system-on-quest/td-p/1058448

[tiny niche]

meta has a sample doing a mirror by capturing and playing back the capture feed stream

[fiery vale]

Okay, so I've tried a couple of things now. I installed a plugin (NativeGallery) to open the gallery. It indeed 'opened' it once. And by 'opened' I mean it showed an empty file browser (not even the gallery) that told me something like 'No app can perform this action,' or so. So, this didn't work. Then, I tried the NativeFilePicker; it worked like a charm. Not exactly the easy user experience I wanted, but it's tolerable to some degree. It worked until I tried selecting an image. Then, it hung up in an infinite loading screen (as shown in the video) , until I pressed the menu button to close it. However, it did get the path and loaded the image correctly tho.

Is there a way to at least close the window after selecting the image?

[buoyant jolt]

No idea 😄 it almost works though and is getting closer...

[fiery vale]

OH COME ON it randomly stopped working when I fixed the passtrough 😭
The passthrough problem didn't even have anything to do with the FilePicker, how did it break it???

"No apps can perform this action."

I guess I'm not finished after all...

and now it's working again

it's so cursed

[frank veldt]

Hi, I am working with Unity's XR interaction toolkit. Does anyone know how I can get a component from the object that I am holding? Im using the XRRayInteractor on my controller.

[snow bolt]

Hey guys, once a long time ago I was working on a VR project and the project had this plugin that would record my VR movements and inputs, kind of like an animation, and i could "Play" the recording so that the controlls and VR rig would move as if I was actually using the controllers, interact with objects I had interacted with, etc. This made it super easy and fast to do small code tweaks without having to actually put on the headset. Does anyone recall what that is called or know of something similar?

[dapper copper]

Yep, that's actually still me :))
I am still trying to resolve this problem.

I will try to explain why I am trying to do this, maybe someone have some ideas about the original issue.

So, I have a unity VR app (on Oculus Quest 2) where I use Application.OpenURL() to open a page to the Matterport site (used for scanning locations and represent them in VR), which opens the Meta Browser over the Unity app.
Ok, on the Matterport website, they have a button for visualizing the location in 360 VR. The main problem is that isn't working. After some research, I believe that this is caused because 360 VR is represented as a separate VR app, so Oculus doesn't let me to launch it because in that way will be 2 VR apps opened at the same time.

That is why I tried the presented solution, but looks that it's completelly closing the VR app.
I am doing anything wrong? I can't minimize an 3D unity VR app on Oculus Quest 2, in order to return to it later, continuing from where I was?

so I am trying to setup openxr, and I put the device tracking origin to floor, but it keeps putthing my head into the floor, it works fine if I use device. Do anyone have a guess on why floor puts my headset into the floor? (Meta Quest 3), using the xr interaction toolkit

[north path]

Why not both :P

[north path]

Which version of Unity, OpenXR, XRIT, and xr plugin management are you on?

Is this just on the quest 3 standalone, or also in Unity?

[dusk pewter]

2023.2.1f1 and latest of xrit and xr plugin management, I am doing it via unity via virtual desktop

[dusk pewter]

Hope you have an idea 🙂

[north path]

Haven't used the tech streams much for XR yet. Just LTS
You can try to see if OpenXR 1.9.1 fixes it if you're not on there already.
If so, try oculus link or a standalone build to see where the issue is

[cosmic marten]

Has anyone tried MR example with quest?
https://github.com/Unity-Technologies/mr-example-meta-openxr/tree/main
this one.
Wanted to test it out, build it, run it on device, and facing an issue, you can spawn objects if you touch the floor, but nothing happens.

[lofty tangle]

I prefer valems videos. But I don’t use either cause they only cover xr toolkit and I don’t use the toolkit.

They’re right though you’ll find useful information on both channels

Haha 😂

How to have an object have continuous collision when picked up by XR Grab Interactable? I don't want the player to be able to make stuff fall through the map

[pastel osprey]

same happends to me... in play mode.... if i use the "reset view" in the options inside of the headset the height is fixed, but i have to reset the view everytime i execute the application/game

[pseudo plume]

im trying to make a slide that the player can pull back before loading bullets, and has no spring, i tried using a joint and such but that seems to cause lag when the player moves while holding the gun or moves the gun too fast, and the player is able to pull the slide both forward and back. i want it to only be able to be pulled back. any ideas?

[pastel osprey]

Is happening in the OpenXR 1.9.1 in the version 1.8.2 is not happening

[lofty tangle]

You have to move object using physics so that it reacts to collisions. If you just change it’s position it can go into other objects

[north path]

Then make a bug report for 1.9.1

sure dm me ill check it out

[lyric prawn]

Good morning everyone!

Last night I was up very late, way later than is good for my day job, trying to make my thus far simple app run on a Meta Quest 2. I got it running in that its in the headset, but as I turn my head the scene didn't change, nor could I see any effect from moving hand controllers.

I worked through several video tutorials, no joy, but they all seemed to be a bit older. I'm running the current Unity, I wonder if someone could point me to a current tutorial, or perhaps some hints as to what to check? There is so much to this I don't even know where to begin looking for the issue.

[potent junco]

How do you properly sample motion vectors in single pass stereo

[mental pumice]

Ever needed to relieve stress? Try breaking glass in #VR 🤜 Cheap, efficient and, the most important part, it's fun!!! 😁 Outcome of a quick 3h dev session today. 🤓 https://www.youtube.com/watch?v=3JB0K5Yw41Q

[buoyant jolt]

Sounds like spam, not questions about using VR in Unity 😉

[buoyant jolt]

There are a lot of ways! You have to use some kind of framework for the Camera view though for it to track and follow the devices properly

OpenXR / Oculus framework etc.

I'd start with an OpenXR tutorial for Quest though 🙂 The hartest part is making sure the manifest and android settings are correct

[lyric prawn]

Okay thank you, I think it was related to me having two cameras. Someone gave me a very basic VR project that os working, so I'm going to look closelty and what is there and what the settings are.

Sorry for these basic querstions, I'm a proficient developer but so much new stuff in this space!

[potent junco]

are motion vectors in single pass instanced VR just compeltely broken in builtin 2021?
it seems to render both eyes to the left eye only

[potent junco]

anyone? this is driving me nuts

[mental pumice]

sry, wasn't aware, that the channel is for questions only! Won't happen again!!!

[north path]

Dilmer or valem or Justin P have greet guides depending on your use case.
I suggest to work with OpenXR, at least on the PCVR side

[north path]

I haven't used built in in years.
If it did work in another version, file a bug report

[buoyant jolt]

I do, I played with it once, and haven't touched it since.

I didnt check the code quality, and I didn't use it for anything.

Still on 2021 here sorry, we found some new critical blockers on 2022 when we retested last week

But on 2021, latest LTS, we had a clean bill of health for handtracking & all platforms

I'll ask my QA team if the hand tracking passed though as I suspect it did

[silver depot]

thanks

[orchid jolt]

Is it worth it to release your VR game on steam? I’m 100% going to release it on oculus but I don’t know if it’s worth it to release it on steam because of the $100 fee. The game will be free but I’m just wanting people to play my game. Thanks!

[north path]

Of it's commercial, it's most likely worth the 100 bucks.

If it's free without any sources on income it's not our place to say if this is worth it tbh.

Porting isn't too hard if it runs on quest (unless if you have a ton of quest specific features)

[north path]

I have gotten it to work in 2022.3, just not sure which exact version.

No experience with that. Sounds doable if you already got a DLC system up

[potent junco]

is the depth texture in deferred for single pass instanced broken for vr in 2023?

[hushed shadow]

Hi I am using open XR and I was wondering if it is possible to have the parent object interactable (grabbable and able to rotate all its child) but also let all the childs be activated for other functions?

was using red cube has parent collider for grabable but i would like if the gray cubes would also let me rotate/translate/rezise the main while being able each of them to be activated

right now only one of them colliders on the interactable component can be targeted (parent or childs interactable)

[north path]

You might need to write some custom code for this to handle the interaction yourself. XRIT might just not support 2 handed interactions with child objects

[north path]

If it worked in a previous version, please file a bug report :P

normal textures work fine tho

green is referenceObj

[storm ether]

Does Defferred rendering suppose to work in VR or not?
I have artifact in PC VR, I suspect either because of defferred or because not enough VRAM.

[buoyant jolt]

Deferred slows down VR, just by its nature, but should really only be required for unoptimized shaders or shaders and post processing that just can't easily be done in forward rendering. That said many shaders and effects are still not designed for VR and may misbehave in both modes including possibly blacking out one eye or appearing in only one eye or gathering reflections incorrectly or from one eye

[tiny niche]

its supposed to work, but it's never the right choice for vr. We just have too many pixels to render and not enough vram bandwidth to make it efficient

even pancake games are generally avoiding it for the same reason

[chrome briar]

anybody know how to add ui for the steamvr plugin?

i want to add ui that is selectable using a pointer (like the vive input utility plugin) but i can't find a suitable way to do that

[hushed shadow]

found my solution by using XRInteractableUtility
//new version DistanceInfo colided; XRInteractableUtility.TryGetClosestCollider(this, args.interactorObject.GetAttachTransform(args.interactableObject).position, out colided); FirstSelectedGameObject = colided.collider.gameObject;

args from override of OnSelectEntered(SelectEnterEventArgs args)

[lyric prawn]

Hi All... I am trying to implement a UI in my Quest 2 VR app. Followed the instructions here:

https://docs.unity3d.com/Packages/com.unity.xr.interaction.toolkit@2.0/manual/ui-setup.html

My event system and canvas are set up just like the docs, and the menu I wrote displays in the game. When I point the red ray from the right hand controller at it, the ray turns white but I can't get the sliders or button to respond. I feel I need to also add interactors somewhere, and I was able to get the entire menu to change its placement based on the right controller being moved, so I'm close.

I have watched many tutorials, but many are out of date (prior to the XR UI toolkit) or just don't cover this well. Here is my setup:

I have killed too many hours on this, and any help will be greatly appreciated, thanks! (edited)

And also:

[lyric prawn]

I made some progress with this. I got so frustrated that I just made an entirely new UI. I added a button, it worked. I added a slider, it worked too. I compared it carefully to the original, could not find a difference.

I tried duplicating the panel from the old one and adding it to the new, that failed. So I added each component manually. Two text mesh pro fields at the top for date and time, then five sliders for month, day year, hour and minute. It all worked. Still could not find a difference.

Finally I added five more text mesh pro fields to the left of each slider, to be used as labels. Now it failed! I have no idea why. I made sure the space occupied by each control didn't overlap. I moved them all around. I finally fixed it by removing text mesh pro fields intended as labels from the UI layer and putting them into the default layer.

I spent an entire day just on this. One menu.

[nova echo]

Hi everyone, I'll write my question also on this channel since It could be more related.
I'm developing a feature for a VR application built in Unity with Unity Netcode.
I'm facing a problem related to server connection from the Meta Quest 2 build of the app.
To make an example, I have 2 build of the app, one is on my quest and the other one is on my PC. If I host a session on my Quest 2, I can join It as a client from my PC, but if I start a session on my PC and try to join It from my Quest 2, it hangs with these messages I attach here, making it impossible to join.

In general, this seems to happen everytime a try to join a session from a Quest 2 build.
If you have any idea on what could cause this issue It would be really appreciated!
Thanks in advance!

[tiny niche]

probably a firewall issue

[lyric prawn]

I can reproduce it easily. On the working UI, if I go and move the TextMeshPro labels from the Default layer to the UI layer, the associated slider stops accepting input. I can do it for any one slider or all of them.

[buoyant jolt]

Without seeing it, it sounds like the UI element could be overlapping

[lyric prawn]

I did check that carefully.

[buoyant jolt]

Also, complete side note, in early XRTK, sliders werent working right in those samples too for some headsets. I can't remember how I fixed it at the time. But I remember sliders being finicky, so might be a bug to report or to work around

The easy way to rule out overlaps though is to uncheck that check for raycasting or whatever on the TMP objects just to see if they are somehow blocking the tracked device raycaster

[lyric prawn]

Thanks, I'll try that.

[lyric prawn]

Hi everyone, if I have a menu that pops up, where is the proper (or at least best) place to put a script that handles the user input? I tried adding it to the Panel that contains the UI components and that didn't work. I then added an empty GameObject on the same Panel with the UI components and added the script to that, still didn't work. I'm trying to have just one script for the panel, rather than writing a bunch of little scripts for each component.

[buoyant jolt]

It depends on the project, If I'm in a rush, I usually add a script on the button that hooks into it as a listener and some kind of enum for the data field. It uses that to read/write to the data system, and then trigger a bigger event back to a UI Manager (so you know text has changed for example). That last part is important as you usually want to have the actual save of the data system triggered by a specific OK button, and to be able to reset it or manage global UI events.

You can get away with a custom script or even UnityEvents on buttons, but on bigger projects where you add hundreds of buttons it won't scale as easily. So it just depends on the use case I think.

[lyric prawn]

Actually I'm trying to update settings in real time as a user moves a slider... Like this )so far just 1 slider coded as a test):

using UnityEngine;
using UnityEngine.UI;
using TMPro;
using Enviro;

public class HandleSliders : MonoBehaviour
{
private TMP_Text text;

private Slider sliderHour;

// Awake is called when the script instance is being loaded.
void Awake()
{
    Debug.Log("Awake() called");
    sliderHour = GameObject.Find("sliderHour").GetComponent<Slider>();
    text = GameObject.Find("Hour").GetComponent<TMP_Text>();
}

void Start () 
{
    Debug.Log("Start() called");
    sliderHour.onValueChanged.AddListener(setVals);
}

void setVals(float val)
{
    Debug.Log("setVals() called");

    text.text = ((int) sliderHour.value).ToString();
    EnviroManager.instance.Time.hours = (int) sliderHour.value;
}

}

The ides was a script like this could hang on the panel itself, but it does not seem like its being called.

[rapid basin]

I have had this same thing happen to me, where due to an issue sometimes you spend a lot of time on something that seems so small in the grand scheme, it happens

[lyric prawn]

Definitely, it's just part of the job!

[rapid basin]

I had the same issue as you once too, where even though you re-created the scene the exact same way, you couldn't find out why something just suddenly worked despite not working in the previous scene

for me it was hands refusing to track at all, in a project with nothing other than the XRI toolkit, which then worked fine in a new scene with nothing other than the XRI toolkit

[buoyant jolt]

Using GameObject.Find might be returning a different slider in the scene. You may want to use GetComponent

Or GetComponentInChild or better yet just manually setting the slider into the Inspector via Unity

My best guess is it is adding a listener to the wrong Slider - but thats without me being certain

[lyric prawn]

Yup I have noticed this type of behavior too. I have a lot of development experience, but this is the first time I have used an environment that mixes dragging stuff around and code to this extent.

[rapid basin]

I have very little development experience and I was confused as hell

[lyric prawn]

Thank you Lloyd I appreciate the suggestions, I'll try them. I'm just not sure the script is called at all because I don't see the debug messages on the console, although I'm running the app in the Quest 2 headset so I'm not certain the would appear.

[lyric prawn]

Well then take comfort that an experienced software guy is also confused 😉

Hi, I am using QUest 3 and I would like to have no boundry setup, but still know the floor height?

Is this possible, I'm tried a few things but so far it seems like

• Floor plane only available in Quest 3 if you do the room setup ( then it recognises the planes and passes them onto Unity )
• If I setup a boundry, then the XROrigin in Unitty is then at the floor height automatically

[strong portal]

Hi there! are there any tools that allow XR interactions with custom hand Tracking? I just need proper information on how i can improve basic xr interactions such as grab, throw, pinch without any collider issues.
(ps. not talking about XR toolkit interactions or MRTK)

[lofty tangle]

Yeah. I mean there are the tool kits as you mentioned, or you can just make your own interaction system from scratch, the tracking data is all in the xr input.

That’s what I did

[strong portal]

I tried using colliers, transforming the target object postion to the palm but the result looks very jittery, motion feels unnatural.

I'm not sure if this is the right way to implement xr interactions from scratch

[lofty tangle]

I never liked using toolkits. So I build my own interaction system so that it works exactly how I want. Idk of any tuts on how to, there used to be a few several years ago, but even then a lot of people just used the vrtk. But now a days most people just use the unity xr toolkit.
What are you trying to do differently that would require building your own?

Or actually your thing was more about hand tracking right? Is it just the part about the hand placement on the objects so it looks more naturally holding things?

[strong portal]

My application uses custom handtracking and the app should support Android and iOS so I can't used openXR or related tools hence the need of custom xr interactions tool.:)

[lofty tangle]

So is it just detecting when the hand is meant to interact, like pose = input? Or the actual interaction on input itself?

If it’s the latter, I prefer using overlap sphere on input to detect interactable objects. Then handle the logic of choosing which object is the closest making it the target and what it does while interacting like filling the players hand position etc.

[strong portal]

I would prefer actual interactions. Currently It's live tracking the 21 landmarks and then I wrote custom gestures detector that would trigger certain modes which was my sort of custom xr interactions attempt.

[strong portal]

That's what I did the 21 landmarks are just 3D spheres with colliders for the detection purpose

[lofty tangle]

Are you trying to do more of a realistic physics based hand where you pick up anything the hands can grip and moving the object with forces?
Or more of a basic version where once you make a pose with your hand it looks for an object in range to grab and sets its position?

[lofty tangle]

And what part are you having trouble with? Are you accurately detecting the pose and calling a function? Or from that are you not able to detect grabable objects.

[strong portal]

Goal is to achieve realistic physics interactions

[strong portal]

Pose detection is working fine function is also getting called but the way object gets attached to the hand feels unnatural as the pose detection is not 100% accurate.

And if I just use the 21 sphere and colliders to lift and object they slip out or glitch out uk?

[lofty tangle]

Okay. Have you worked with active ragdolls? It’s where a physics body uses configurable joints moving with forces to match an animated body. You could do the same thing with hand tracking. Make a ragdoll hand using configurable joints and colliders, use drive to move the joints to match the hand tracked hand, and make the tracked hand invisible 🫥 so you only see the physical hand.
You could also add a physics material to the hands colliders to give it realistic friction. This would have it move like your tracked hands but react to in game colliders
This should let you, for example scoop you hand into a bucket of marbles and pull out a hand full of them.
It’s more complicated and you got to do a lot of tweaking to get all the values just right to fell realistic.

[lofty tangle]

The simple way is just snapping the object position to your hand when pose is detected.

And if you want physical interaction with the environment. Just have the position of the hand move using physics so it can’t go through walls.

[strong portal]

This approach sounds soild.

I'll implement this and get back with the results! Thankyou @lofty tangle

[lyric prawn]

Using the XR interaction toolkit, I'm trying to react to the menu button on the Oculus 2 left hand controller. I learned I can capture a trigger press with "XRL LeftHand Interaction / UI Press" but I have not figured out how to get the menu button.

Hey everyone, I'm a Product Manager on the XR team and want to share our latest roadmap (https://unity.com/roadmap/unity-platform/arvr) regarding Unity’s XR offerings. This should help you understand what’s coming down the pipeline, and more importantly, provide a channel for you to express what features are most important to you. This will be a critical part of our development process to validate what features we work on next.

We’re committed to reviewing all the feedback that comes through the portal, so please vote for features that are important to you and leave detailed explanations in the corresponding feature cards to help us understand your needs. If you feel like something is missing from the roadmap, feel free to use the “Submit a new idea” card to share your thoughts.

We can’t wait to see what you build!!

[sweet crane]

i need to know how to test me vr game

when i run it in quest link

it does not do anything

[buoyant jolt]

Can you expand on what you mean about it does not do anything?

[sweet crane]

si

when i click the play button

on quest link

it does not let me play

[buoyant jolt]

Ok, pretend we can't see your screen and project. What does it do? Does it blink green? Does it show black? Does it show a scene but no controllers? Does it spin in circles? What does it does not let me play mean?

[sweet crane]

ill send a picture

[buoyant jolt]

Hopefully that'll help

[sweet crane]

ok

cant send a picture

also

ill tell you what happend

[buoyant jolt]

Honestly though I just need like a one sentence description of the problem, and hopefully the errors in the log

[sweet crane]

let me put it this way

how do you test your game

on oculus

[buoyant jolt]

Give this a spin, May just be wording in one of the input systems:

https://forum.unity.com/threads/accessing-menubutton-on-oculus-quest-2.1164416/

[sweet crane]

where is the start button tho

new to unity

[buoyant jolt]

My scenarios different than yours. I usually do my development on a vive. Then build tests onto Pico, Quest and Rift S. If I wanted to run it on a Quest instead of a vive, I'd launch oculus desktop, enable link, and just press play (or control+P). But I like a vive or index when I'm coding as they are more comfortable

[sweet crane]

thing is

when i press play

it does not let me play lol

it does not go full screen

at all

[buoyant jolt]

Yeah again, that could mean a lot of different things

[sweet crane]

but it plays the game

i also have a error

i dont know if this has anything to do with my problem

[buoyant jolt]

Assuming you have a VR capable PC, and you have VR configured properly, when you press Play it should show on the screen and on the headset.

[sweet crane]

it does

how do i play the game tho

[buoyant jolt]

That's OK, that's a warning, it might stop something from being interactive in VR but work otherwise

[buoyant jolt]

So, if it shows everything on the headset and turning your head and looking around does what it is supposed to, that's great. Next it's adding controls to your game so they do something

[sweet crane]

could you send me one of your games

and i could test it

to compare to my game

or i could send you my unity thing

and you could fix it?

[buoyant jolt]

No, that sounds a lot like work 😄 I'm still not sure anything is broken

[sweet crane]

let me try to send a video

ok

watch that

its also not fullscreen

[buoyant jolt]

Ok, that doesn't explain much, unfortunately. Having it play in full-screen mode on the screen, there is a toggle button you can press to have it do that. But this doesn't show any info on the VR side or what's happening there

[sweet crane]

Ok

[sweet crane]

do i open air link

and go to virtural desktop

and open it from there?

im just wondering how i open my game on vr

[buoyant jolt]

I think you need to start with some tutorials...

[sweet crane]

already tried

[buoyant jolt]

Ive already explained what I can to the best of my ability

I'm afraid I'm not sure how else to help

[sweet crane]

so you dont knopw how to open a game on quest?

[buoyant jolt]

#🥽┃virtual-reality message

As for playing full screen on the desktop there is a toggle for it.

If that doesn't work, you are doing something wrong or misunderstanding how it works, or just not able to communicate it to me in a way that I understand

[nova echo]

Thanks, It seems It was firewall related

[lyric prawn]

Thanks Lloyd I went through that thread, looks like my version of Unity may be a bit newer. It looks like in the actions lisy, UI is set to the left trigger. I tried to add a binding for a menu or a start (as that thread referenced) but could find neither.

Clicking on "tracked device" or any of those options did nothing.

Also:

[buoyant jolt]

Yeah the new input systems a bit of a nightmare at times

When I get back home I'll peek at our bindings and see what I set it as

[lyric prawn]

Thank you!!!

[silver depot]

any ideas how to troubleshoot why EarlyUpdate.XRUpdate is taking so long. its tanking my framerate

thanks on a quest 3 on device

[buoyant jolt]

The bottom half of the cutoff graphs is an important part. But check your render stats in the game view for draw calls and vert counts

[craggy belfry]

anyone know how to fix blurry text using TMP world space on quest2? my render scale already set to 1, no MSAA (already tried 4x but it still blirry), with FXAA

[spark quartz]

Hi!
we have an assignment to create a VR Application for the ocolus Rift. Everything is working fine but one thing that really does not work is how we are able to display two different things in the VR Googles and on the monitor. Basicly we want one player beeing VR doing stuff and then we want to have another one in front of the computer doing other stuff. We tried to use the multi display stuff which kinda works but only if we have 2 monitors on the computer itself (https://docs.unity3d.com/Manual/MultiDisplay.html) which is not ideal.
We also tried out stuff with setting the one camera depth different and not showing the eyes which kinda worked but had the isseu that we want two different Rendered "Screens" like e.g. Screen 1 is for the Vr googles and Screen 2 is for the normal comupter display. Can anyone help me with that?

[silver depot]

@buoyant jolt

[edgy relic]

Hi all, anyone ever faced this error : Could not find active control after binding resolution. It happens in the demo scene when swapping from controllers to hand tracking and viceversa with quest 2. Thank you in advance.
Here you can fine more details about it: https://forum.unity.com/threads/openxr-update-1-7-0-1-81-error-could-not-find-active-control-after-binding-resolution.1465583/#post-9495058

[lofty tangle]

Use large font size and scale it down

[buoyant jolt]

Its been a while since I set it up but cameras can have the target eye set to none (main PC display) and operates separate from the VR camera

[buoyant jolt]

That looks like graphics processing to me. What are the poly and drawcalls like for that scene?

[silver depot]

@buoyant jolt 81k tri 50k vert

[buoyant jolt]

Can you take a screenshot of the stats panel on that scene?

[silver depot]

I posted one up above, did I miss one of the sections you wanted to see?

[buoyant jolt]

I'm trying to figure out if a bunch of real-time lights are destroying your polycount or something

[silver depot]

I turned off all lights while testing

I'm using meta scene api, and passthrough

[buoyant jolt]

No, the game view tab has a little stats button. It shows all the drawcalls and polygon counts post everything while playing. It's a good way to see if somethings messing with your draw calls

[silver depot]

oh, thanks, i'll get that

[buoyant jolt]

It's a long shot to be honest

But what I'm seeing in the profiler, is the CPU chilling and just waiting for the graphics card to render.

[buoyant jolt]

Yeah that makes sense. It's looking OK there. I'm not sure what's bottlenecking it, it looks GPU, but the stats counts look more than healthy enough

Batches are more than fine, poly counts more than fine. Cpu itself seems fine.

[silver depot]

i find it strange i'm not saving anything by batching, I thought having this shader on a lot of what i'm rendering, would reduce batch count:

its instanced

or do i have the wrong understanding of how that works?

[buoyant jolt]

That looks like an occlusion shader, it's meant to make things invisible

It might be an expensive shader because of the occlusion

If possible, I'd do a test with just standard shaders in case it's that particular shader slowing everything down

A custom shader gone sideways can cause that slow down, it's worth checking

Maybe an easier way is to disable most of the meshes and do a play test.

We know their poly count and draw size isn't an issue. So it would point a finger at the shader without reconfiguring everything

[silver depot]

doing a build test now, I'll give them a go and let you know after. Thanks for the ideas, I appreciate it 🙂

i'm going to get muse to review my shader for performance issues as well

[buoyant jolt]

Fingers crossed, recreating a shader is a lot easier than dealing with other issues, and would be resolvable. So fingers crossed

[silver depot]

getting the shader to this point was brutal, the game doesn't work without it

it takes the walls from oculus room setup, makes them pass through, and drops your room into another world, so out of the doors and windows in vr, but your in your room

had to do a bunch of csg operations to modify most of the mesh in run time

which means i have nearly no static objects

[buoyant jolt]

Ah, OK, pass-through will definitely carry some impact to the FPS as well, but i haven't had to mess with it yet

100k tris as non static shouldn't be a problem though

[silver depot]

with how far i have it stripped down right now, my gut says it has to be related to that . . . but its a huge setback to have to find another way to get the same effect.

[buoyant jolt]

Especially on a Q2 or Q3

[silver depot]

q3

I didn't test enough in build while itterating. the issue exits in editor, but is magnified in build, and neither will pass correct fps. kept working on features, instead of tackling this issue 😐

[buoyant jolt]

Thats not bad though, optimize when you need it 🙂 there is nothing here that can't be solved somehow I'm sure of it

[silver depot]

and thanks for the encouragement 🙂

[spark quartz]

But this is kinda hacky I feel Like.

Because you have to Change the depth of the Camera for some reason so it gets rendered differently

But I could Not find anything on doing it other than that or needing to have 2 physical Displays or using a Render Texture whichs also Kinda even more hacky...

But there is No other way of settting the VR Googles as a physical other Screen?

[buoyant jolt]

I'm confused about what you mean. The cameras have settings as to what device they render to, which was your question. Not sure how that's a hack, that's exactly what it is there for. But if you want to find another way, by all means go for it

I would argue, however, any other method of doing that is the real hack

Maybe I don't understand your problem. But yes, there is an option to show it on desktop or the headset. And yes you can use nested cameras in that case to show certain layers (I.e. a UI overlay for desktop only, which is pretty common).

My understanding is you wanted a camera to show on the headset, and a different one to a PC, where the PC could interact separately. Giving them separate cameras is how it is built to operate.

[spark quartz]

What confuses me is why it still needs a different depth setting for it to work and Not be overriden by the other Camera

[silver depot]

@buoyant jolt looks like intended behavior, this is from unity-discover:

its expected behavior, and I missed the memo

[thorny remnant]

Hi, I'm following the Unity VR tutorial, and at step 5 it says "enable all available OpenXR Feature Groups" under Project Settings > XR Plug-in Management > OpenXR > Feature Groups, but as soon as I check "Mock Runtime" the application no longer launches on the headset while Oculus App is opened.
https://learn.unity.com/tutorial/vr-project-setup?uv=2021.3&pathwayId=627c12d8edbc2a75333b9185&missionId=62554983edbc2a76a27486cb#

Why does this happen and why the tutorial tell to check this box? The documentation says "Enabling this will take over whatever current OpenXR runtime you might be using" but I don't understand what that means.

[lyric prawn]

Hi Evereyone... As someone new to VR, and looking at the MQDH performance analyzer, I'm wondering what the most important parameters are and what is considered good, poor, great... Is there a simple guide someone coul;d point me to?

[north path]

The easiest way to check performance is OVR metrics (or some other metrics system depending on your system) and check fps, gpu util, cpu util, etc.

The exact changes in rendering depend per project

[lyric prawn]

Thanks, I have been doing that. There are a few different frame rates, apparently a 6 core CPU, then I run 3 of them are at 100%, memory use... I really don't know how to interprate all this data.

[north path]

If the framerate is fully stable then it should be fine :P
Otherwise I like to start with the Unity profiler

[pine bison]

I have 35 FPS in a current project on Quest 2 Looking forward to the profiling and optimalisation there

[north path]

Oof, have fun with that one :o

[rain lotus]

Hi, we had trouble with quest pro stuck on cpu and GPU level 3 while the app target level 4 in the same place on quest 2 and 3. In result the app run at 47fps on quest pro and 72 on quest 2.
It's a mixed reality app, I wonder if GPU level is locked in MR for quest pro for power or thermal reason. Does anyone have an Idea?

[pine bison]

Sounds like something you should be asking on the Meta developer forums rather then here to be honest, I haven't hear anything about this personally

[rain lotus]

Yes I send it on meta forum too. But perhaps someone encounter thé same issue here

[rapid basin]

Steam user stats for VR headset used

if anybody was interested in such numbers

[silver depot]

@buoyant jolt found the fix to my issue you were helping me with yesterday, it was vulkan. changing to opengles3 got rid of all the garbage:

[buoyant jolt]

I'm going to remember that, thank you for sharing

[silver depot]

it may of been a red herring. I thought it looked good at the start, but the testing i've been doing the past few hours, make me thing i jumped the gun.

my confusion remains after everything else has been deleted from the scene:

[lavish zinc]

I’m trying to import a scene I created with post processing into a VR template scene to test it using its controls. How can I make sure the VR camera shows the imported scenes post processing. Adding the cameras to the post processing layer didn’t seem to work.

[fiery vale]

Is anyone familiar with Oculus Integration for Unity? I'm really confused, there are so many ways to implement a simple ray to interact with a 3D canvas. There are the OVR Raycasters, the UIHelpers prefab, the Controller Ray Interactor, etc... . Half of the options are obsolete, some are random scripts, others are prefabs, and there's a lack of proper documentation. Existing tutorials aren't helpful because the structure of the OVR integration plugin appears to change with every update.

Does anyone know the correct method for implementing a ray to interact with the world space UI? Currently, I use UIHelpers, as it's the only thing I've gotten to work. It's really janky, has an ugly, non-native laser, and doesn't really work with the second controller. That's part of the reason why I think that it's intended for debug purposes.

[tiny niche]

interesting, i think the change in those numbers since previous years might indicate less vr games being played on steam overall

[tiny niche]

if all you need is a canvas, you could make it very easy by manually creating a Ray and a Plane struct and doing plane.Raycast(...)

then you just need to cull at the boundary, the dimensions of which you can get at the canvas

[buoyant jolt]

I don't really recommend using the OVR framework itself, as then you are locked to only a single headset. Is there a reason to use that over OpenXR and the XR toolkit? Warranted, the toolkit is very rough and barebones in most cases, and not really production ready in of itself. But it's a solid base to work off of...

[tiny niche]

ovr framework works with more than just the meta headsets. it was only during the rift-days where it was oculus specific

[buoyant jolt]

Weird I've never seen it work with the Pico, Focus, etc. But it's been a long time since I've used it. We were all VRTK before custom OpenXR

It was pretty feature rich at one point when i was messing with it (early quest 1 release era), so it'd be nice to use

[rapid basin]

PCVR is definitely losing users to cordless VR, yeah.

[tiny niche]

stand alone you mean, since i suspect most of the quest2 users in that chart play over air link

[rapid basin]

right yeah, idk why I always call it cordless

shows my age..

i'll be interested to see how much the Quest 3 section grows by this time next year, and if Index will be able to hold their percentage

[tiny niche]

i suspect it will. I imagine most quest3 users are mainly former quest pro users and some quest or quest2 users

the quest3 also has battery life issues which would probably be a dealbreaker for many index users

[rapid basin]

oh really, battery issues? I have not seen much of the 3, but I know the 2 certainly didn't stay powered on for long.

[tiny niche]

2 has significantly better battery life than 3. But i think the 4-6h we get out of 2 is fine

[rapid basin]

4-6h? Mine got 90 minutes at best, although 2 hrs is what they advertise iirc

I only got 6 hrs after getting the bobo m2 pro, changing out battery packs every 2 hrs

sucks to hear though that Quest 3 battery life is even worse...
