[pine bison]

the solution for this is to have two sets of hands, in a way. You have one transform that represents the real location of your hands, and then you have a second transform that tries to follow the hands wherever they go, but are affected by physics. Then you use this second pair of transforms to control your rig

You can not change the field of view of the camera since this is set by the VR hardware. And even if you could it would most likely be disorienting and sickness inducing to the player

how can i develop on quest 2 using playmode in unity?

[boreal aspen]

use airlink

[median cobalt]

i am using it

and when i press play on unity nothing happens

[boreal aspen]

can you see you computer screen in the vr?

[median cobalt]

yes

[boreal aspen]

try running throw there

[median cobalt]

tried it

still nothing

[boreal aspen]

do you have a link cable or any usb-c cable

[median cobalt]

yes

i have c cable

[boreal aspen]

plug it into your pc and turn off airlink on you quest

plug the cable to you pc and quest

[median cobalt]

have it

now?

still nothing

[dense roost]

try setting the build platform to android and set in the project settings to oculus, and also try reopening the project because that's what works for me most of the times😅

[open pier]

hello everyone 🙂 i started a project with oculus quest 2 and everything was working perfectly, but when a build for my vr, the build comes with a terrybl quality

anyone knows why or know resolve it

?

[dense roost]

maybe try removing all quality settings and just leaving one so it is the same in the editor and the build, but other than that I don't know sorry

Hey

[muted laurel]

What is better and what is more easy to use and to work with?
OpenXR or SteamVR?

The troubles I already had on OpenXR was: If you use a vr headset and combine it with different controller, like in my case: HP Reverb G2 Headset with Valve Index Controller. They don't match up together... even with Open Space callibrator running in the background!

[deep fox]

@muted laurel perhaps you might find some solutions in some of the videos and articles by SkarredGhost, I remember he recorded a vid some time ago for a hacky method to have cross-platform project for VR, which imho is still not a trivial task.

about mysterious 45 fps cap it seems I am not the only one: https://forum.unity.com/threads/vr-build-locked-at-45-fps.954660/ Could anyone tell me who could be knowing on how to debug this?

[muted laurel]

I dont have performance issiues, i took OpenXR to support all VR plattform, but The thing is, that I can not have different conntrollers, that are not made for the different headset, even with steamvr and OpenXR in the background.

But my other fear is, I dont know if steamvr supports also all the plattforms like OpenXR?

[deep fox]

I'm glad you don't have performance issues. I do x) #🥽┃virtual-reality message

something is overriding your settings for the controllers

[muted laurel]

Does steamvr support already build in: oculus, vive, Windows mixxed reality and valve index?

Maybe I delete my Openxr scripts and assets and begin from scratch with SteamVR instead.

I only will publish it on steam, so...

[deep fox]

afaik steamvr needs oculus software running to detect quest and touch controllers, WMR perhaps has the same thing -needing Microsoft software running in the background and telling the SteamVR what to do.

[muted laurel]

But I dont eant to make my game exclusive for only one type of headsets. I want support: oculus, WMR, vive and index...

[deep fox]

You should also take into considerations what would your end users use. While Valve Knuckles are great, and while Reverb is also quite good, it is more likely that there would be either Reverb users with Reverb controllers or Index users with Valve Knuckles, so there could be some considerations if what you are trying to achieve is the best what you could do for your end users.

[deep fox]

by default OpenXR should be handling just what you described. This is the idea behind OpenXR itself. To provide universal standard, however it is still quite early with OpenXR. It is possible, however, as you see, it is not so much ready ready. Needs additional effort to make it work as intended.

@muted laurel idk how much this will help you with what you need, however here:
How to build, test, and run OpenXR applications in Unity https://www.youtube.com/watch?v=TmXExs4ccYs

Now I need some help. Anyone :)? #🥽┃virtual-reality message

[muted laurel]

I already have OpenXR...
I just want to know, if steamvr does also support the same features?

[north path]

SteamVR has per finger controll on the index controller. Other than that I have not seen much difference in term of features (next to OpenXR being a broader platform with better hardware support)

[mental sentinel]

Need to make sure in your project settings that your headset is listed and selected.

[hollow zodiac]

Hello I am trying to upload a Vrc world but I am getting errors and have no clue how to resolve them

[deep fox]

answering my own question, so someone could benefit from it in the future:

I tried almost everything I could try, after reading Unity forums, reddit topics and the docs. I found it. You wouldn't believe what was the reason.

In my case the reason of the framerate almost capped at half of the 90fps easily achievable in other apps was...

having both the Game and the Scene tabs visible while having project running in VR was causing the framerate drop almost in half.

Yes. This can be reproduced. Unity 2021.3.8f1 (LTS). If anyone would have similar issue and would try all what I mentioned in original message and with no results - try not having both Scene and Game tabs visible when you hit Play. Then, magically, you will have your framerates as normal. Kind regards 🙂

vr virtual reality low fps fps halved 45fps vive pro issue

[distant gazelle]

I'm getting the angle between the position vectors of the motion controllers, but the angle I get changes based on position in the scene. Can anybody provide some insight on why that is and a different way to go about it?

[polar valve]

I’m trying to get a lens flare shader to work in VR… the Shader takes the viewport position of the sun as a uniform property, and this property is being set inside OnPreRender for the camera. In the C# debugger I can see that it’s producing a different value for each eye. But the flares are being drawn in the same position for each eye - and I grabbed a frame with renderdoc and confirmed that each eye has the same value in its constant buffer for the sun position.

Any ideas? Are you not allowed to change shader properties in prerender for the right eye?

%^#&@!%#^!&@%$& I don't understand why but using Shader.SetGlobalVector worked instead of setting it directly on the material

[thorn mortar]

hi, i've been struggling with this for a few days now but now I sideload application using sidequest but cant run in editor, not sure why this is happening because before we used VRTK it was running on the device now i am using open XR and it doesnt run in the device using air link or cable, if you have found a way please let me know

[median cobalt]

it was a knock off oculus link cable, which was working kinda well. I bought a new cable not original oculus link and its working now

[thorn mortar]

@median cobalt you mean that the fake cable is working good now?

[median cobalt]

It was USB 2.0

[leaden plover]

hey guys, what are you using for ads in VR (e.g. quest 2) ? google ads, unity ads, maybe something third?

[flint wyvern]

Hey im using XR and im having a hard time figuring out how to read the position of the one of the joysticks on my quest, can someone recomend a guide

[north path]

Most VR games don't use those ads, since it doesn't have the play store etc to link to and a flat screen ads break the VR experience a lot.

Maybe look into banner ads etc

[north path]

The joysticks is just a vector2. The position is vector3. What doesn't work exactly?

[flint wyvern]

Im strugging to read it generally

[north path]

Do you use the new input system?

[flint wyvern]

Yeah the action based one

[north path]

Then add an xr controller position then

Or just use xr Interaction toolkit

[ripe flower]

I think they mean the input from the joystick, not the position

[north path]

The vr pathway on unity learn is great

[flint wyvern]

I am using the toolkit

I just want to know the position of either joystick

[ripe flower]

if you are already tracking the controllers, you can get the transforms position

[north path]

You need to look for it in the input lists or just press it when listening to a button

[flint wyvern]

Im using an XR Origin and it has left and right controller children, does that count as tracked?

[ripe flower]

if you attach an object to the hands, and move your controllers in real life, do they track?

[flint wyvern]

One min let me check

Yes they do

[ripe flower]

then yes, they are tracked

so if you simply want the position of the controllers, you could use the transforms. if you want inputs from the controllers, you can learn how the new inputs system works, and how to get and read those inputs.

[flint wyvern]

I just wanted the position of the joystick

[ripe flower]

How much about the inputs system do you know

so then I know where to start

[flint wyvern]

I mean Im a professional c# software dev, im not a game dev

Im aware that the new system is event based

[ripe flower]

create a new script, or use one you already have and add public InputActionReference joystickInput

then in the unity inspector you can assign the LHC or RHC primaryaxis input action to that actionreference

in the start method you need to enable the input action, so do joystickInput.action.Enable();

then wherever you want to read the input you do joystickInput.action.ReadValue<Vector2>();

[flint wyvern]

I take it that I then get two floats, the x and y?

[ripe flower]

yes, the vector2 will contain the x and y of the joystick

[flint wyvern]

Alright

[leaden plover]

So what are the vr games use for ads? I tried to integrate the unity ads banner, but its not showing in VR and I couldnt find documentation how to place and alig it in a canvas

[ripe flower]

for the not showing in vr bit, is it set to be a world space canvas? other then that, I have no experience in ads

[north path]

Most just are paid, use subscriptions, or have IAP.
Otherwise use anything that runs in world space, but income probably will be lower since you don't really get clicks

Have you seen many VR games with ads?

[leaden plover]

https://create.unity.com/vrads

this looked interesting for me, but when i submit it, I get some strange non utf8 characters, no redirect, no e-mail

this would be the best solution, this would fit in a vr game, i know the normal banner ads are not fit in vr ... but i am out of options

[fathom minnow]

What would be the best way for creating sprinting and stamina for unity XR/VR?

Edit: I am going to try checking XR input and switching the locomotion system depending on if the player is clicking the sprint button

[ripe flower]

Is there a difference between sprinting in VR and 3D?

[fathom minnow]

I'm talking specifically about using the unity XR toolkit locomotion system

[ripe flower]

then I don't know

[fathom minnow]

ok

[autumn pewter]

Guys, I have made an object interact able using VRTK 4, I can not see now in the headset

[north path]

Look for the momement code and add a multiplier (or maybe there already is a variable for movement speed?). The rest is the same for any 3d controller

[leaden plover]

guys, what are you using for (keyboard) text user input? e.g. for login etc

[fathom minnow]

With XR I just designed my own keyboard with UI but if your developing for meta/oculus I think you can use just the built in keyboard somehow

[fathom minnow]

I found it works just to check for input and depending on that and how much stamina you have to allow you to sprint or stop sprinting

[leaden plover]

did you try to use the built-in? (I am using XR interaction toolkit)

[fathom minnow]

Is there such thing?

I'll check rn

[leaden plover]

you said its possible to use the quest built in keyboard, but i couldnt find a solution how to use it

[fathom minnow]

I did see that with the OVR plugin it seems there is some sort of keyboard

[leaden plover]

then i guess for xr i have to design my own keyboard

[fathom minnow]

You can just get the OVR plugin

as well

[leaden plover]

is it good idea to mix the ovr with xr?

[fathom minnow]

Wait

I think that the OVR keyboard

is only for like

Tracked IRL keyboards, but I know there is a way to use the oculus keyboard as I have seen games use it before

[leaden plover]

the keyboard is one of the basic input's, i can not belive that they forgot to add a keyboard in to the XR **Interaction **toolkit

[pine bison]

It’s possible to use the Quest keyboard with a simple addition to the android manifest @leaden plover. But if you’re building for more platforms than Quest, you would need a custom solution

I’ve used this one for cross platform and it works fine https://assetstore.unity.com/packages/tools/input-management/vrkb-virtual-reality-keyboard-151812

[fluid siren]

hello I have a question, I want to make an NPC that can be grabbed like in the game Blade and Sorcery, does anyone have an idea of ​​how this interaction can be done? I exactly want to do, for example, that you can grab some part of the body and be able to hit it and then throw it and it gets up on its own.

[north path]

Probably using ragdolls and IK for blending between player actions and the traditional animation it has.

Or maybe fully IK/procedural animations. Would be awesome

[fluid siren]

Nice, I was thinking of using Animation Rigging, to test how it looks, if it works I'll send a video to show you, thank you!

[north path]

Awesome! Feel free to ping me, would love to see :p
Animation rigging is a big part of IK yeah, so you will probably use that or another 3rd party asset

[verbal obsidian]

Why is my inertia like 10x bigger when I'm wearing the headset compared to when I'm not, with Oculus XR Plugin?

I need to add 10x the force for the same height of a jump, when my MainCamera is linked to my Oculus.

It's a Generic XR Device with Position tracking, but there isnt mass anywhere

[verbal obsidian]

Ok, for SOME reason, DRAG was being set to a high value, when I loaded the headset.

I made the "fall down" script slow down the fall by adding drag when jump is held while falling, and that occulus drag magically disappeared, because I also have to set drag every frame when I'm not falling.

But the object being moved by the script is not the occulus, it's a mother node, so I guess there's something fishy going on

Welp, at least now the game works both with and without VR 😄

[median cobalt]

i cant see my controllers in unity playmode. I am using openXR on oculus quest 2 on unity version 2021.3.4f1. but when i open another project which was made with oculus integration it works

I want to create a render scale slider to my indie game and was wondering if anyone could point me in the right direction for how to accomplish that? I found a really nice tutorial on how to do it here: https://catlikecoding.com/unity/tutorials/custom-srp/render-scale/ However, I don't have the same scripts such as "CameraBufferSettings", "CustomRenderPipelineAsset", or "CameraRenderer" that they reference in the tutorial. I figured this could be a difference between 2D, 3D, or VR projects in Unity but I'm not sure. Anyone have any insight?

[mild igloo]

Hey guys I am trying to figure out how to pick up a cube with the Oculus controller but keep it flush with the top of the controller ring. I am going for a pushing action. Right now I have a raycast and when I am close enough I pull the trigger and the wall moves to the hit point but its the center of the wall. Should I add the scale on the axis/2 so that it stays flush?

Hey everyone, I have some 360 pictures of a room. Is it in any way possible to be able to walk through that like i am in the room itself with mouse/keyboard or VR headset or would I only be able to look around? It's just 360 pictures, no 3d scans. Is this possible or would I have to replicate the room itself in blender or with 3d scans if I wanted to walk around in it (using photogrammetry for example)?

This is the picture in question

[storm ether]

I don't think that what you can walk in 360, that's impossiblr

[tender zephyr]

Yea I figured... Guess I'll make a 3d model of the room and 3d scan the furniture. Thanks anyways!

Hi, the teleport is not working in my htc vive controller, however I can grab and can do other stuff, I used VRTK 4.
I am using 2021.3.8f1

[gilded wyvern]

Bas is... Very, very complicated. I've spoken with Lyneca (one of the big modders and warpfrogs spell guy) and while it looks simple-ish on the surface, its so very interesting but complex further than that.
You might be able to create a custom interactor/interactable. Im not too sure how you'd go about that, and my vr is out of commission rn so i wouldn't be able to tackle it myself

[fluid siren]

Yes, i understand, like first step,i m trying that grab anywhere part to NPC, like second step, implement IK for try interactions with physics.

[gilded wyvern]

your best bet would be to try physics first, as you grab with physics in bas

[gilded wyvern]

If you can successfully grab a ragdoll that isn't animated or anything, you can move forward and look into animating the ragdoll

[fluid siren]

Nice, i trying to do this.

[mild igloo]

Has anyone here manipulated verts in VR? I am struggling with getting it working well. The verts move a small amount but not 1 : 1 with the controller or the raycast end point

 Vector3 posZ = primaryController.transform.position + transform.forward.normalized * primaryController.rayDistance;

                    for (int i = 0; i < surface.Vertices.Length; i++)
                    {     
                        surface.Vertices[i] = new Vector3(surface.Vertices[i].x, surface.Vertices[i].y, posZ.z + 1);
                    }

                   selectedObject.GetComponent<MeshFilter>().sharedMesh.vertices = surface.Vertices;

                   selectedObject.GetComponent<MeshCollider>().sharedMesh = surface.filter.sharedMesh;```

[gilded wyvern]

are they flagging as being touched or anything?

Also, children of an object don't have to be in the same layer as the parent

you're free to change them

I'm trying to make a turning button. Like the one on the image. But I'm trying to limit the rotation (so that it can only be rotated for 180 degrees on a axis) of the button, but I can't seem to get it right. Anyone that could help me?

[tender zephyr]

If I put my Quest2 in Developer Mode and use apps like sidequest, will that make me lose my warranty? If not, what would make me lose warranty?

[pine bison]

No. Tinkering with hardware or jailbreaking is what voids your warranty

[tender zephyr]

Awesome, thankyou for the response

[gilded wyvern]

You can make it a velocity tracking interactable, if you're using the XR Interaction Toolkit, put a configurable joint on it and lock the position, then set up your rotation limits accordingly (locking the rotation on the axes you don't want to rotate).

[twilit lance]

Ah okay, thanks!

[gilded wyvern]

np, @ me if you need anything else

[twilit lance]

I will do that for sure, thanks!!

:)

[storm ether]

anyone can help me, how to make damage from gun to puppet master

[twilit lance]

@gilded wyvern So I got a rotating button right now. Now I want to make that if I rotate the button, that it stays on that rotation. And then if I grab it again to rotate it further, that I can rotate it from that exact position. But right now when I try that it automatically goes back to the rotation my hands is in if you know what I mean. Do you know a way to fix that?

[gilded wyvern]

lemme have a quick look at the xr toolkit docs

what version of the toolkit are you on btw?

[gilded wyvern]

Depending on what version of the XR toolkit you're on, the grab interactable (assuming that's what you're using) should have an option that says "match rotation"
see what that's currently on and then try changing the value and testing it

[twilit lance]

2.1.1

[gilded wyvern]

okay, should be able to change the "match rotation" thing then

give it a try

[twilit lance]

Alright, if I can find it 😅

[gilded wyvern]

Should be a boolean somewhere near the bottom of the grab interactable inspector thing

[twilit lance]

It is not there. This is what I have

Or waaiit

It might be named differently

Oooh found it, if you click on the square next to "Use Dynamic Attach" you get the options of Match Position, Rotation

[gilded wyvern]

there ya go!

that might help you

[twilit lance]

Yep, thanks!

[twilit lance]

@gilded wyvern One last question, I've been trying to find a way to make the button have like multiple different positions. Just like the washing machine button, it has different modes it can be set on. I want that with like 8 different modes. How would I do that? Google can't help that much, since I can't seem to find what I want to find

[gilded wyvern]

hm

that's a tricky one, methinks

gimme a moment

[twilit lance]

Sure!

[gilded wyvern]

you would have to compare the local rotation to something for sure

maybe a list of a custom class (WasherMode, for example), that has an angle specified. If its within a certain tolerance, then its that mode or whatever

The other one, which just jumped into my mind is this. might be more confusing though
you set up a number of modes or whatever you want to do with it
You take the rotation range on that axis
and do something with the % operator

im not quite sure on the maths though

[twilit lance]

I see, I'll try it out. Thanks!

[gilded wyvern]

With these cubes, are they on the same layer as your piano keys, or are they on the same layer as the guitar

[gilded wyvern]

Here's what I do

I create a layer for the character, which collides with the ground or default layers

And if something interactable has moving parts, or subcolliders

I have a separate layer for the hands which doesn't collide with the player, and I have another separate layer for moving parts on interactables

the hands can interact with both the interactable layer and the interactable moving parts layer

you can have one hand layer, as the hands won't cause issues when they overlap

I know

what layer is your body collider on?

and does that layer collide with the default layer

What layer is your body collider on?

no

for the player

If you have one

Does that collide with the interactable layer?

I know

Does the Player layer collide with the interactable layer in the collision matrix, in physics settings

hm, okay

What layer are your hands on?

There's no left or right hand layer

No, not a left hand and right hand object

I meant a left hand and right hand collision layer

Are they InteractionLayers or Collision Layers

Or are they Tags

Show me your full inspector window

no

well

Make a single layer for hands

Make sure the hands Do not collide with the Player layer

The hands must only collide with any layers that will contain objects you want to interact with either by grabbing or pushing

The reason you are being pushed around when the string colliders are on the Default Layer, is because your body collides with the default layer.

Making a hands layer that collides with the interactable layer, but does not collide with the Player layer is your solution

Yeah, that should be alright

Try it now, with the string colliders on the interactable layer

They should, yes

That's irrelevant to the strings, but you can always try it with being able to pick it back up

[gilded wyvern]

did it work?

Do you have the cubes on the strings set as triggers or colliders

And are they on the Interactable Collision Layer

Are they on the right layer?

Okay

let me think

Are you 100% certain you put the script to make the sound on the cubes

Okay
Are your hands on the Hand layer?

Are your hands on the hand layer

This is completely unrelated to my question

Are you sure the strings are on the right layer too?

no

I mean

Are you sure the string colliders are on the right layer

Try making a layer called Music or something, and put everything that makes music, on that layer

put your keys and strings on that layer

and make it only collide with the hands

see if it still works on the piano

that will tell us if layers are the problem

[gilded wyvern]

Could you have muted or turned the volume down on the audioSources on the strings?

hm

im honestly not sure what might be doing it?

Show me the inspector for your string collider, like take a screenshot of the entire inspector

I can't think what the issue could possibly be then

No, that won't be it

the number of sounds won't be the problem

are you getting any errors at all?

go straight to the guitar, hit the strings, and see if it gives you the error

Then I don't know what the issue is

yeah :/

[north path]

There is an older asset on the asset store. No official way to do it sadly.

Do you use unity?
Assets are just scripts etc, so I don't see why it's not possible to use them

Feel free to write your own system, but not many will be able to help

Ahhh

https://github.com/De-Panther/unity-webxr-export

Woah this is supporting the latest unity version

That's new to me

@crisp sigil @storm ether you can use multiple things to get data

The log file also is generated on android and should be visible in the file manager.

You can make a dev build and use the profiler and use the console like normal, even with native builds

And external log tools should work fine

And you can make a custom console you can see in world space and print the logs to that. Also really nice to have

hey guys,I have unity 2019.3.7, and the XR toolkit package requires 2019.4 and later!
the package used to work with my version when it was in preview stage, how can I get it?

my internet is so bad that it will take forever to download a new version

[north path]

You might be able to force it in the packages manifest and change a file responsible for verification in the package so unity doesnt give warnings.
It might break however. Is there a reason you are using this really old unity version?

[quick sentinel]

Is there a reason you are using this really old unity version?

my internet is so bad that it will take forever to download a new version
and its stable so its ok for me

[quick sentinel]

but can you explain it more to me, sorry I dont understand

[north path]

Then do it overnight or something. Backporting stuff on your own can cause a lot of issues later on. Especially since input is different per VR headset, so this sounds like a bad idea

If it's simply a case of waiting I am not going to help much.
But you can go to the packages manifest file and change the package version for VRIT

OR just use the version which already works for you (;
Don't expect to have a new package to work on a unity version over 3 years old

[quick sentinel]

thanks, trust me, if its an option I would do it, I live in syria where there are a lot of power cuts, the internet speed is 2 mega BITS per second for 5 users, its so hard for me to download a new version, and downloading it requires me to download the building stuff for webgl and others, so its not an option for me

[north path]

Maybe try an internet cafe or something?

[quick sentinel]

bruh, internet cafes in syria?

Don't expect to have a new package to work on a unity version over 3 years old
I just hope that there is a way that I can get the preview package that was released when my version was the latest, what I will be doing is really simple, its just a really tiny project im not even making it for myself, so its no long term or something, so in my case the preview un-stable stuff will be ok

thanks for your time anyway @north path

Hello I have found issues while developing my game

It seems whenever an AI object or just a non-static specifically AI object enters the spotlight or is about to the game freezes completely

This doesn't happen in the editor but does on the APK when I tested.

[storm ether]

I've got a problem with my controllers in unity. so a couple of days ago i was adding some netcode to a game i was working on and hadn't tested it at all and so I'm coming back now and for some reason my hands are no longer tracking in unity i have double checked that they work outside the game using steam vr but while I'm in unity no matter what i do no input will be received to the controllers (tracking, button presses, everything). could someone help me figure out the problem with my controllers?

[marble wedge]

Hey guys, does anyone know how to lower the resolution for only the VR camera?
Here is the forum post: https://forum.unity.com/threads/dynamic-resolution-on-vr-camera.1333062/

[gilded wyvern]

Question is; why are you trying to lower the resolution of the VR camera?

what are you trying to achieve by doing this?

[north path]

Performance probably

[gilded wyvern]

Then you can look into other things such as Fixed Foveated Rendering, where the centre of the screen is at full resolution and it is lowered just at the edges, where the player cannot see

And Dynamic Resolution on a VR camera might cause problems for the player themselves too

[north path]

Yep, I responded in the forum post as well

[gilded wyvern]

@marble wedge Your best bet is likely not to reduce VR render resolution. There are other options, such as having the same camera render on the main and VR displays, which is more performant than having two separate cameras with different resolutions. You can also look into other general optimisation methods such as Occlusion Culling, or you can look at VR-specific methods such as FFR. Don't reduce the resolution of the VR view, as this can cause sickness and/or general discomfort while playing.

[marble wedge]

@gilded wyvern The reason why we're trying to lower resolution is for recording purposes. The recording camera should have a stable FPS, but if you're enabling a recording camera, you're rendering twice.

[gilded wyvern]

Are you recording footage using an external program?

Or is something in Unity doing the recording?

[marble wedge]

Yeah. It's a recording camera which allows to have a higher FOV than the default camera.

It's for us as well as for streamers/YouTubers.

[gilded wyvern]

What's the performance impact from using two cameras like?

[marble wedge]

Double the rendering, which results in a more unstable FPS, because the rendering costs have doubled.

Which results in stuttering @ the recording camera and a messed up recording in the end

[north path]

That's why big studios record on extremely high end PCs or simply have a rendered cinematics

[north path]

Is just the recording messed up or also the gameplay in VR?
If just the recording, your recording settings in the tool you use are not the best

[marble wedge]

Both actually.

Because the computer needs to calculate double the rendering

[gilded wyvern]

You should probably look at optimising rendering somehow rather than dropping the vr resolution

[marble wedge]

So you're not sure how to lower the resolution for just the VR camera?

Because fixing rendering performance will take way more time to fix than lowering the resolution, I believe.

[north path]

Better performance is always good for the end user though
I am not sure how to drop the resolution of a single camera. From what I recall you need to use render textures and a blit for this, which might get advances, especially for VR which can give issues with blit and render textures since it's a stereo view

[median cobalt]

how can i detect controller position and calculate the direction where i am swinging my controller

[median cobalt]

basiacally i want to calculate the rirection where the controller is pointing and for example mark it with a arrow

[gilded wyvern]

You can easily get the direction your controller is pointing in by getting the transform.up or transform.forward for your controller (i forget which one it is because controller orientations wacky)

or you can get the direction of motion by either doing the maths yourself with positions, updating the reference position at the end of every frame

[median cobalt]

can u tell me more on how to do that please

@gilded wyvern

if u will have time reach out to me, thanks

[gilded wyvern]

Here's roughly what you'd do
on start, you'd set a vector3, OldPosition (or something like that) as the position of the controller
then at the start of a frame, you'd want to set a vector3, NewPosition or thereabouts as the position of the controller again
new - old (i think it is) and then normalised gives you the direction

you should be able to figure the rest out

[barren spindle]

for some reason light only shows when i look in a certain direction?? idk if this is just sidequest being weird but making sure just incase

[leaden plover]

what are the best settings for the best quality in VR? (e.g. anti-aliasing etc)

[north path]

Best is 8x MSAA, 8k textures, ultra high res LODs

But no current PC will run that properly, so you need to clarify a bit

[leaden plover]

in the UI canvas, the pixels are well visible. Only the unity app and other programs look nice

[north path]

What di you mean? @leaden plover

[leaden plover]

I will try to make a screenshot tomorrow

[fathom minnow]

!Help! The player falls through the ground or doesn't teleport correctly when I set its position to a certain vector3 for a teleport system

[north path]

Is the player rigidbody set to continues?
And is it a premade teleport system or did you code it yourself?

[fathom minnow]

For teleport I made it just set the position to spawn for like respawning and the rigidbody is not set to contiues

I may have fixed it but just on a side note the player can glitch through walls when sprinting like into a corner

[north path]

Set it to continues.

And make sure you teleport so the feet allign with ground, not the middle of the player

[fathom minnow]

One problem when I have set it to continues in the past the player could easily glitch through walls

[north path]

Whut? Discrete could have those issues but continues should not. It's the most accurate

[fathom minnow]

Well basically the player speeds into a corner and continuously runs into it they can fall out

[north path]

Maybe try other continues settings?

Or increase wall thickness

[severe saffron]

its probably the movement method

if you're setting position of the rigidbody not using moveposition or addforce

then yeah, you'll go through walls

setting transform.position or setting rb.velocity will ignore collisions

[tame bane]

hey i need help so i downloaded the oculus integration and imported it and now my hands dont move but the line renders for the menu do

[north path]

What doesn't work exactly?

[north path]

How are the hands etc setup? Do you use the OVR player? Did you follow the oculus startup guide already?

[solar sphinx]

Hey VR Devs, Need your help in understanding a problem, I am developing experiences for both Oculus and Pico neo 3. So far the visual quality of the experiences are not looking good.

I am getting something like an anti-aliasing issue or jagged edges or shimmering like artifacts when seen from the headsets.

The recordings from Oculus and Pico are coming out near 4K also the PC preview is looking flawless.

What am I missing...Is there anything I need to do specifically.

[solar sphinx]

For a quick answer, I created this comparison...This experience is built for Pico neo 3 eye.

Overall, The visual seen through the headset is at 60% to 80% of what is seen from the in-game recordings

[north path]

Look up the official oculus quest unity development guide
Dont see what hinge joints have to do with anything

[north path]

Do both use the same quality preset?

[pine bison]

Sprite textures do not have mipmaps enabled by default. You need to turn that on for world space UI

[leaden plover]

How can I do that?

[pine bison]

On the texture import settings

[solar sphinx]

The image comparison was a mockup, The left is the recording from headset, But the right one has many artifacts like I mentioned...The project is URP based. I usually use only medium preset and delete all other presets

[severe hare]

So basically, the problem is that the unity xr grab interactable just enable grabbing for any interactor that act with it I found a way to detected the interactor class. So I know wheter it a ray or hand. However, Even I put zerocode in the if function it still enable grabbing.

[severe hare]

Ok, so to simplify it further

I found Grab() function that said to be called every time that I press select. Im not sure how this Grab() work, but it must be a problem. Is there a way to prevent it calling??

[pine bison]

What's your goal @severe hare? To disable grabbing on an object under certain conditions?

[severe hare]

Yep.

the basic goal is

[severe hare]

this one

So I want one object to be grabbable by hand but do something else by ray

[pine bison]

Right, that's a better way to put it

My initial thought then is that perhaps you shouldn't use the Ray Interactor but instead make your own script with a raycast

[severe hare]

Okay, tbh I dont know what choice do I have. really new here thanks

So I could detect if the ray hit the object and retrieve the object properties with raycast right??

[pine bison]

I'm not too familiar with the XR interaction framework but as far as I know, the ray interactor is just made for the express purpose to grab things from a distance

[pine bison]

And yes that's the idea

[severe hare]

Okay thank will try it

[next flame]

Hey, has anyone tried using Unity Recorder to record 360 videos?

I have an issue where my recording is not looking in the right direction. It seems to be facing North, but it is not facing where my camera is facing.

Anyone knows how to fix this? 😦

[quick sentinel]

hey, there was an option called "virtual reality support" in the player sittings in the old versions of unity, how can I enable it in unity 2021 ?

this option makes the game view like in VR and give the options to show: left eye, right eye , both eyes

[pine bison]

This option has been deprecated and replaced with the XR Management System @quick sentinel. Last version with what you're describing is 2019 LTS

[quick sentinel]

oh now I see, thank you, so should I install the XR Management System package and it should work?

[pine bison]

It's pretty straight forward but I would recommend following a youtube tutorial

[north path]

Depends what system you use

[mild igloo]

Oculus Integrations

[mild igloo]

Just grabbed RGB Haptics. Seems promising

[lofty tangle]

first record what the controller is doing, position/velocity, and check if the changes from the current frame and last frame fall inline with what you think a swing is. then do something when it determines that a swing has taken place

[storm ether]

can someone help me fix double vision caused by TAA?

[pine bison]

The XR Origin represents your play area, and your play area is an area you define yourself, with its pivot at the floor. As such, the pivot point of the XR origin will always remain on the floor, and when you walk around the play area, the origin does not move. You can not parent things to the XR Origin if you want it to follow your player around. Instead you would, like you say, attach it to the headset camera somehow

[wet jewel]

Hello guys, I am making a Multiplayer XR app with Photon PUN2, when entering the other level, all players enters the room and there are more than one XR Origin in the herarchy I have been trying to disable all the scripts on other player which are not owned locally (using PhotonView.IsMine). first of all they do not get disabled and if I disabled them while running it in editor my own controller stops. what should I do

Please Help me

[pine bison]

You should instantiate different prefabs for remote players than the local one @wet jewel. There shouldn't be any more xr origins loading at all

[wet jewel]

Okay this make sense, But when a player joins a scene it comes with a controller and there is only one prefab of XR controller, if there will be no more XR Origins then there will be no other players. Please explain more

How can I instantiate an independent prefab of XR Origin in the scene

[pine bison]

I'm not familiar with photon, but the high level idea is that you sync the headset position and hand positions for each player. You would then use a prefab for remote players that just reads this information

[twilit lance]

while the other options would be either the hands not matching the desired position, or just having floating hands, which are completely hidden when something is grabbed

[opal lantern]

Hi Anyone Working on Projects related to LENOVO Think Reality?

[north path]

I don't understand, why doesnt it work on quest?

Tip: use .wav and compress it in Unity to vorbis (probably with streaming enabled for memory usage). Otherwise you compress it twice

Depends on the project. Check the profiler I guess

I dont have enough info to give an answer. Too many settings etc that can influence that

Again. not enough info to pinpoint it. Run the profiler

Yes, then you compress it to ogg and then unity does it again. Unity compresses it upon build

I use VR Interaction Framework, which already has this

[severe saffron]

btw scene switching in editor is horrendously slow. Native build? Scene switches instantly. Doing it in editor? Takes up to like 4 seconds!

Also did you enable streaming loading? Or are you doing the compressed in memory option that means the entire song must be loaded ASAP?

[north path]

Did you even try it on the quest? @weak thistle
Always test on device when possible

A paid VR frameworks. Google exists (;

Otherwise child it to the main camera I guess. Or lerp the rotation and force the position

Then check out what I fully set.
Force the position to 1 meter under the headset or whatever and rotate it with the headset.

For full body I suggest looking into FinalIK

Don't think so. It's not that huge of a difference, but for the next ones use lossless

[severe saffron]

click the audio clip asset

check load in background

set load type to streaming

blammo, non-thread stalling streaming clip

and yeah, loading will be way faster if you build it native. I just wrote a scene teleporter in my own game. Its completely fast and asynchronous on the quest 2

but in editor? totally stalls it when loading

this is known behavior async load doesnt load async in editor

streaming means it loads chunks off the disk

otherwise it has to load the entire song into memory

yes a native APK build.

PCVR means the PC will vary and I can't tell you how fast a scene will load; but in the case of a quest 2 native build with about 100 modular elements in a scene(prefabs, audio,mesh,texture)?

Loads faster than I can make a transition for.

<1s

android likes ogg

https://gamedevbeginner.com/unity-audio-optimisation-tips/

you might find other combos work well though

vorb it up

PCM makes bigger files but uses less CPU.
OGG smaller files more CPU.

the article I linked basically tries to pro/con each combination

but basically you gotta profile it

yes it probably wont even recompress considering you preserve the sample rate

just check if this changes

at 100% it should remain the same size

in my example it shrank because it was wav2ogg

FinalIK will allow you to use VRIK and set up a full body rig

but a rig on what?

FinalIK is not an entire VR package, just for animations

so yeah you'd probably need some kind of framework for grabbables and whatnot

valem has tutorials using animation rigging which is free

assuming you dont wanna pay for finalIK

I mean sockets exist right? Can't you just float a socket under the main camera?

teleport it every frame somewhere below the camera

yeah thats why I said to teleport it

parenting is just messy

teleporting to worldspace works 100% every time 😄

socketTransform.position=CamTransform.position + CamTransform.forward*0.3f+ CamTransform.up*-0.3f;

blammo, now the socket is 0.3m in front of you and 0.3m down

probably too big of a number but thats for you to play with

it rotates if you tell it to

just slerp it to match the camera's flat rotation

socketTransform.rotation=Quaternion.Euler(0,camTransform.rotation.eulerAngles.y,0);

Quaternion destRot = Quaternion.Euler(0,camTransform.rotation.eulerAngles.y,0);
socketTransform.rotation=Quaternion.Slerp(socketTransform,destRot,Time.deltaTime*5f);

slerpy makes it smooth

[pine bison]

Valem and Justin do not make pro level tutorials @weak thistle. They are one of the best points of entry for getting into VR dev in unity. You should look for their introduction tutorial series

[pine bison]

In this day and age?

i am using open xr
i want to use the interactable velocity tracking, without the grabbing system

the object i want to velocity track will never leave the player's hand

firebase loot locker playfab

theres a lot of stuff out there or you just roll your own

pretty much anything that works with android will work on quest

Hello guys, I have been brainstorming on this "How people make cross-platform apps", user can enter with VR and with Desktop, Do they make two different controllers or they make one with this new input system.

But input system is so complicated to me that I can't figured it out How can I make my controller accessed by both VR and Keyboard/Mouse

Any Thoughts

[north path]

VR and mouse/keyboard requires you to make a VR emulator or make 2 different game systems

For multiple controller types just map multiple buttons of different controllers (or generic buttons) to the same action

[wet jewel]

How can I map my keyboard inputs with "Move" action which runs on joystick of VR

[north path]

Click on the plus and add multiple bindings

Looks like you already got it?

I'd say make the game first and then focus on porting

[wet jewel]

I have already made the game.

It's a noob question but I don't find any keyboard inputs

[north path]

You added a vector2 input. Keyboard is just true or false, not a vector2. Add a double binding instead

When pressing the plus you have multiple options

[wet jewel]

[lofty tangle]

Anyone get issues with drifty movement when keeping the center of the collider in-line with the player and using input to move the rigidbody?

[wet jewel]

Hello buddy, I have seen you answering questions on unity forum related to this topic, I was publishing my XR app on Oculus App Lab, But this error pops up, how can I fix it

The focus aware manifest meta-data tag must be set with required="true". More information can be found here: https://developer.oculus.com/distribute/vrc-quest-input-4/

[full basin]

It seens that if you use Oculus Interation SDK in Unity Store, it will set the manifest for you automatically.

[wet jewel]

Yes it does, but while building your apk, Unity modifies it, I have decompiled it and changed the manifest and recompiled it again, now I am facing this error and I don't see any tag in manifest related to focus awareness

If there is any other way so that manifest don't get modified or I don't have to do any extra work after build apk, Please share with me, It would be great help

[full basin]

I have tried in Unity 2020.3.28f1 with Oculus SDK and it works, and my apk was pass in Oculus App Lab already. Have you ever try to create a new empty project with the Oculus SDK? If your current project use some thrid party plugins or sdk, maybe something modify your manifest.

[wet jewel]

okay I will try that

[wet jewel]

Hello mate same error, but this time camera permission wasn't there, I have noticed the difference between old project and new project in android manifest, The new one was different so I copy pasted it but still no progress. Any thoughts

[gilded wyvern]

when using the XR Interaction toolkit, is it possible to get which hand is attached to an interactor? or would i just get the controller component and check which hand its using?

[north path]

https://issuetracker.unity3d.com/issues/xr-perf-quest-2022-dot-2-and-trunk-shows-significant-gpu-increase

Nice!

[severe saffron]

quest 2 has multiple cores so depending on the task multithreading can be beneficial; but you have to profile the overhead of creating threads and make sure the task in mind fits.

its not like multithreading is a magic bullet

there are constraints I'm too derpy to explain myself 😛

I find its good for pathfinding and mesh generation but I find myself writing a lot of the agent logic and raycast stuff locked to unity's singlethreaded stuff

in my game i have a canvas with a button UI and i was wondering how i could make it so that it teleports me to the next place

please anyone?

[lofty tangle]

probably, but it was harder to figure out for me than creating my own interaction system from scratch that lets me do all the things the XR interaction toolkit doesnt.

[buoyant jolt]

Same with us

[north path]

Not a vr issue right. Set the VR player to a different position?

Have a list/array of positions and go to the next one each button press

[gilded wyvern]

I might have figured it out lmao

[mighty cobalt]

Do the OpenXR and SteamVR plugins conflict?

[pine bison]

Yes, you can not have both active at the same time. If you're talking about the XR System Plugins

[mint mural]

Heya,

So im currently trying to do some stuff with VR.

I was wondering if there was any documents/examples about connecting Input devices (e.x Joysticks, Gamepads, huggable pillows) with USB-A to USB-C converter or bluetooth.
Or if it was possible to use a different input system and having the game on a VR.

Also is it possible to get the amount of input buttons on an input device and the name of the button?

Anyone have any tips?
Thanks in advance!

[north path]

You can use any input the platform supports the way you want.
Just make sure it actually works on the quest if you target that. Windows has a lot of freedom with this

If you want to make a huggable pillow you gotta go through the regular costom controller setup stuff

[mint mural]

do you have a link to documentation for this

I am lost where to go atm when i use

List<UnityEngine.XR.InputDevice> dev = new List<UnityEngine.XR.InputDevice>();

it returns 0 for the input devices

[pine bison]

Well how do you populate that list?

[north path]

Google how to make a custom controller in Unity. Idk what hardware you have etc

[pine bison]

Additionally, this list will only give you available XR hardware. It has nothing to do with gamepads and the like

[mint mural]

oh that explains

[gilded wyvern]

Do the opposite - scale up the buildings
If you want to give the impression, looking at Moss, that the player and the creatures are smaller, then you can make the buildings bigger to give that impression

[pine bison]

You can scale the camera too. This is how you do small scale content in AR without messing up AI and lighting

[severe saffron]

scaling the camera is by far the easiest way to accomplish this. No need to mess with model scale at all!

[mystic quiver]

does anyone know why my game is giving stain on the eye? i first thought it was my lens but i dont think it is bc when i look at something from far away it does not happen.

[severe saffron]

eye strain? Thats VR!

seriously though is your game fast motion or something?

if you're using quest 2 the fixed focal distance is something like 5 meters

anything closer / reading up close will strain your eyes because the lenes don't adjust

[gilded wyvern]

if you scale up the buildings, it will feel as though the character is smaller. Lets say you want the player the size of a mouse or something, and the buildings to appear "normal" sized; you could scale up the buildings so that the player and the other creatures look incredibly small next to it

[shell kayak]

You can easily scale the VR camera rig to whatever you want, so the player is a giant in a real-scale world.

[gilded wyvern]

You could also try that ^

[radiant magnet]

Hi All,
Did anyone faced this problem before?
"Addressable not working in quest 2? "
And working in the editor?

for the apk size more than 1gb. or loading it from obb?

[gilded wyvern]

It sounds quite clear - Addressable package apparently doesn't work on the quest 2. Best bet would be to have a look around, and to ask in #📦┃addressables as well

https://forums.oculusvr.com/t5/Unity-VR-Development/Addressables-Loadpath-in-Quest-2/td-p/932725

Have a look at this post, this is the first thing I could find on it.

[radiant magnet]

Thanks for the reply, I will ask in that channel as well. Also I will look at the above link.

[gilded wyvern]

https://www.gamedeveloper.com/programming/unity-addressables-it-s-never-too-big-to-fit

This one might also be good to read through too

This link i just sent does talk about porting psvr to quest though

Although, it may well be transferrable to what you're doing

[radiant magnet]

Thanks I will take a look at that one as well.

[gilded wyvern]

Not sure if anyone's got a clue on this but if you've played Hotdogs, Horseshoes and Hand Grenades, you'll know of the quickbelt, which allows you to "lock" magazines into the pouches and grab magazines infinitely. Does anyone have any clues on how to do this, using the XR toolkit? im brainstorming ideas myself

[floral stream]

Hi everyone, Does anyone know how to make a vr cross platform game like mobile or desktop?

Like this https://www.youtube.com/watch?v=LP29BxhvHfc

[limber niche]

Depends how you want to do it. Cross platform using Unity’s services is quite easy.

[onyx blaze]

Anyone have a code for making jumping in vr?

[lofty tangle]

It’s not much different from jumping in any other first person game. But depends on your player controller

Unless you want the person to irl jump for it to jump in game

[floral stream]

Example or reference please 🙂

[north path]

XR Interaction Toolkit should be cross platform by default with OpenXR

[wise tartan]

can anyone help me? im trying to add jumping to my unity xr game but dont know how?

there is no tutorials and when i followed one it didnt work]

[smoky wedge]

so has anyone tried to build for the pico neo 3?

[lofty tangle]

#🥽┃virtual-reality message

[pine bison]

Yes, with the SDK provided on their site. Worked fine for me

[wet jewel]

Does any body knows why my hand controllers are stuck below me in the app, I really don't know what I changed which caused this

[smoky wedge]

thank you, i wanted to be sure cause i was aiming for crossplay

[buoyant jolt]

We have many clients running our stuff with Pico 3s. Nothing but love. You can use OpenXR with it.

From there you can build a hybrid Quest, Pico, Rift, SteamVR, WebVR and WMR build with very little plug-ins quite easily.

Pico 2 however is a very different answer

[balmy locust]

This happened to me today when I added Oculus Integration and the Oculus XR driver. I reverted to a plain Open XR / XR Toolkit version and it fixed it. I had only added Oculus Integration for the android manifest generation for applab, but the package is huge and did something nefarious.

weirdly the tracking worked, and the locomotion worked, but I lost position (But not rotation) of the controllers.

hopefully you have some kind of version control?

[wise tartan]

can someone help me add climbing to my unity XR game.

[brittle hornet]

OpenXR, screen space UI that I want to show up on the deskop monitor sometimes because compltely impossible to click once i hook up the index remotes for my open xr game

impossible as in it doesn`t detect mouse hover, or click events

Ive tried removeing all objects from scene except the UI and the Event system for the Ui and it still doesnt fix it

[brittle hornet]

Using unity 2021.3.3f1

It works perfectly if I switch the game to simulator mode

[wet jewel]

Thanks man letting me know about this but I haven't pushed this work yet, I think I have to do this all again!!!

[wet jewel]

So this is manually you can remove oculus Integration, there is a oculus folder in the asset open it in explorer, close unity and delete oculus folder open unity again it will work fine and oculus integration package will be removed

[wet jewel]

But I have a question for you what if I want to use other features oculus integration offers, I can manually add android manifest in my case but what if in future I want to have that keyboard feature they offer then what? again my controller will go crazy is there any fix?

[storm ether]

Hello, I am trying to follow a tutorial by valem about his physics hands, but it doesn't seem to work properly as my physics hands are following the real model hands. Any help how to fix this ?

[balmy locust]

Dunno. I'm not even 100% sure it was the Oculus package that was responsible. Git / Git LFS is continually useful on stuff like this.

[mystic depot]

hi there
Is there any way to easily detect which hand is holding an object with the XR Grab Interactable script on it?

[tawny terrace]

when i play my game the controllers dont follow my actual hands and idk how to fix it

they just get stuck in air and move with my hand but stay still and dont move with me

[north path]

You have given no info on how you track the hands. What package do you use for your VR player?
What headset? Unity version?

[tawny terrace]

so i think its Xr my headset is oculus quest 2 and my unity version is 2021.3.9f1

[tawny terrace]

i think package is XR idk but my player is called XR rig so

[north path]

Probably XR Interaction Toolkit?
Did you follow a guide already?
Maybe check the VR development pathway on Unity Learn :p

[tawny terrace]

k

[storm ether]

Could someone take a look at my question please

[north path]

If it's his guide maybe ask on his socials as well

[buoyant jolt]

I'd suggest asking the person who made the tutorial

[buoyant jolt]

Job postings aren't allowed on the discord channel

[storm ether]

Ok, can you help with proper channel

[mild igloo]

What is the best way to push an object with your VR controller?

been stuck trying to push a cube with my controller without using physics..

[severe saffron]

why not physics

[mild igloo]

I tried that but it was a bit wonky.

I tried to apply my controllers speed to the transform forward of the cube but it just shot off into space . The goal is to raycast to the cube and push it or pull it. I can't figure out how to apply my controllers forward movement to the cubes. The cubes can only be pushed on its forward (back or forth)

tried cube.forward = controller.forward but that inherits rotation of the controller and can be moved/turned in all directions.

parenting is not an option since it basically does the same

[wet jewel]

I am pretty sure about it, that it was oculus integration package, I already had "Oculus Hands" folder in my assets and oculus integration rewrote it which was causing that problem. So if you have "Oculus Hands" folder then remove it from the check list while importing oculus integration

[wet jewel]

Hello Guys, I have a query regarding to the development environment is there a way to build and run my app and test it on my oculus quest 2 instantly rather than building it and uploading it on oculus hub, installing and then using it. It takes too much time to check my changes

Oculus Android apk acts totally different from the desktop application or unity editor run

[north path]

Use SideQuest or adb to install the apk

[pine bison]

Just do build and run, no need to install the apk separately

[north path]

Oh yeah

[mystic depot]

is there a way to toggle haptics?

[neon crane]

hi ,
when I'm working on a vr built, I usually build the test file on unity and then install it on oculus/pico a thrid party app like sidequest, for some reason sidequest has stopped working, it time out while " checking apk blacklisting" .. does anyone know any alternative way to freely build and install test builds via sidequest or any other alternative ?

[pine bison]

Just do it via ADB if you're comfortable with command line @neon crane. It's super easy and you can use the Android SDK installed with unity

The command is just adb install -r [PATH]

[balmy locust]

good to know. I won't ask how long it took to figure that one out!

[north path]

Yes, did you google it already?
I think all VR solutions ship with haptics support

[mystic depot]

Yeah, but in the xr toolkit the only method I found was like hapticimpulse(intensity, duration) which isnt a toggle

[north path]

Ah, that is useful info.
Maybe make a script that keeps triggering halticimpulse in a coroutine or other method untill you manually stop it?

[wet jewel]

Hello guys, sorry to bother you again, This question is regarding to the oculus app lab, when ever I update my apk on oculus hub, oculus provide option to update but it never updates it, I tried uninstalling it and reinstalling it, but it only worked once. Is there any solution I can over come this

[north path]

Do you use a keystore?
If the signature from this or the application folder (com.companyName.ProjectName) change it will not update

[zenith pasture]

whats the highest amount of tris you guys usually aim for when making apps for quest 2?

[pine bison]

Oculus documentation sets the Quest 2 at max 1 million triangles rendered https://developer.oculus.com/documentation/unity/po-art-direction/

[wet jewel]

No keystore is same, as far as I know One cannot publish or update same app with different keystore

[north path]

Personally the absolute max for me is 800k since I have some skinned meshes and custom shaders as well.
I aim to have 500k on screen most of the time

[zenith pasture]

Colleague of mine has 600k tris and 600k verts and is experiencing some lag, but that's probably not enough to cause some more significant issues, right?

[north path]

I mean, if the game goes under 72 fps it can be rejected by oculus and it can be uncomfortable.
It's not as simply as a triangle count = this fps

On android draw calls also is really important. As well as using the right shaders etc

[wet jewel]

is there any particular reason that unity apk act differently on oculus quest 2, It works totally fine on unity editor or as a desktop app

[zenith pasture]

I do realize that, that's why I asked whether the tri count could be the main culprit or if there's another issue

[north path]

I truely cannot say this without seeing the project

[north path]

Yes, one platform is windows and the other is android.
Explain the issue if you want support

[wet jewel]

In unity editor and desktop app nothings jitters, I can see my hands, move and all but when I build android apk and published it on oculus it was jittering everything was stuck can't see my hands can't move

why is that

[north path]

Jittering can be bad performance. The quest is slower than your PC most likely and has a tiled GPU.

No hands being tracked might depend on how your VR player is setup. What packages do you use?

[wet jewel]

XR Interaction toolkit!! If this answers your question

and the same app worked fine, in the previous build

[north path]

For android in xr management, do you use the OpenXR package or Oculus?

[wet jewel]

Yes for sure

[north path]

Then compare differences to that version I guess (if you use version control)

[north path]

It was an or question lol

[wet jewel]

I will try to figure it out this way

[bronze cypress]

Hey i need some help, ive been trying to setup ik for this character model but for some reason every time i click play it gets shoved down like this

anyone know why this is happening?

[shadow valve]

Does anyone know how to connect objects kinda like legos? I tried spherecasting to find the nearest object and setting that object as parent but all that ended up doing was now the other object moving effected the scale of the child object. Which led to some weirdness with the cube's shape. Any help or reference material to read would be appreciated.

[balmy locust]

not sure if you fixed this yet. Shot in the dark, but are you incrementing the version number properly? It's android, so you need a 'monotonically increasing integer' version number. Just add one every time you push to app lab.

[mint veldt]

i need some help with rigging something for a game if anybody could help?

[balmy locust]

what are you using to generate the manifest?

Please vote on it

[somber salmon]

Hi,
I made a vr game with open xr, the issue i have is when the oculus device is removed (it goes to standby) and then worn again, the orientation and floor positions are messed up.

Could someone please help me out

: (

[leaden plover]

I simply just built an apk with unity, and tried to publish on the alpha channel

[leaden plover]

this is very similar to the issue what i mentioned a few days earlier

[balmy locust]

Do a little research into generating the manifest.

[north path]

Yeah it's a widely known issue, but performance still can be acceptable on 2021, just not optimal.
A bit back there was another similar issue which gave us a small xr improvement in 2021.3.10, so update if you can

If you have a project in which you can reproduce performance issues make a bug report for it. The lack of repro projects is a part of the slow fix

[north path]

OpenXR package 1.5.1?

[leaden plover]

i am using 2021.3.10 and i can reproduce it mostly on big rendering scene

[north path]

Then make a bug report with both 2020 and 2021 versions attached:p

[somber salmon]

1.4.2

[somber salmon]

I have no idea why its happening

[sinful aspen]

Does anyone know how to simulate VR input via code in an automatic test (using Unity Test Framework)?

In my automated tests I need to move the hands around, grab things, etc... I'm using the latest standard Unity XR plugin stack and the XR Interaction Toolkit

[north path]

Maybe try 1.5.1?

[somber salmon]

Is it a prerelease?

@north path

[sick creek]

Hello does unity render the whole world in VR, or only camera fov for devices like oculus quest 2

[balmy locust]

Unity has a mock VR controller somewhere among the XR packages. Driving that from a test would be my first try.

[buoyant jolt]

Both. It can draw the whole world. It can do occlusion culling (showing what the camera can see). Foveated rendering reducing workload. And some other things that you may not care about.

It depends on what settings you disable

[sick creek]

@buoyant jolt I haven't done any special settings its a VR build with default settings, but I find that even objects that are out of view seem to be generating draw calls

[buoyant jolt]

Their occlusion culling isn't very good to be honest

It has a hard time determining what is in sight, out of sight, and seems to still leave things in draw cycles in a lot of Unity versions

[sick creek]

@buoyant jolt I don't have occlusion culling enabled, but intuitively I would have thought that unity ignores objects that are out of view, I had heard of frustum culling etc, years ago so thought that may have been the default now

[buoyant jolt]

Yes, frustrum culling doesn't catch all objects very well, where occlusion culling is supposedly better at it. There is some good information here: https://docs.unity3d.com/Manual/OcclusionCulling.html

[sick creek]

@buoyant jolt thanks

[autumn pewter]

every time I step in the scene and try to grab somethings, my scenes move down and it goes so far from me ? why is it so ?

[sinful aspen]

Yeah I tried that actually, I think your talking about the MockHMD XR plug-in, I tried that actually but it won’t run in test scenes for some reason, always throws a somewhat cryptic error

All I need is a simple way to control the VR input from script, like trigger buttons, change hand/head location etc…

[wet jewel]

Check line at 9 you have to add this and it will resolve your problem. Check mine manifest

[leaden plover]

It's working, thank you @wet jewel !!!

[wicked bane]

I have created as an exercise a Oculus Quest 2 scene, can someone with an Oculus test it?
I don't have a VR unfortunately 😅

[north path]

At least tell what it is. If you want people to playtest something for free for you at least make it easy for them and don't make them dig for what they gotta test @will_DGD#7826

LMAO he left

[severe saffron]

🤣

[somber salmon]

Fixed this, i was building with the XR simulator game object (from xr interaction toolkit). Once i disable and build again, it worked!

[wet jewel]

Hello, I made an object but I can't get near to it with my XR Origin, something invisible stopping me to get closer to it, I have put a box collider on XROrigin and object, I don't want to remove them, and this should not be the problem coz I can bump into the wall which has a collider but in my scenario I can't

[north path]

Use collision layers or IgnoreCollider in code?

[undone meteor]

So I am trying to set up what i believe is called a stereoscopic set of cameras for vr, on the oculus quest 2.
I have my vr functionality working however i want to make each eye be assigned a different camera, however each camera only lets me pick between None or Both instead of Left and Right

I have also tried manually setting it with code, however this variable changing doesnt even seem to be represented in the objects

    public Camera CamMain;
    public Camera CamBlue;
    public Camera CamRed;

    void Start()
    {
        Debug.Log("main cam has " + CamMain.stereoTargetEye);
        Debug.Log("Blue cam has " + CamBlue.stereoTargetEye);
        Debug.Log("Red cam has " + CamRed.stereoTargetEye);

        CamBlue.stereoTargetEye = StereoTargetEyeMask.Left;
        CamRed.stereoTargetEye = StereoTargetEyeMask.Right;

        Debug.Log("Blue cam has " + CamBlue.stereoTargetEye);
        Debug.Log("Red cam has " + CamRed.stereoTargetEye);
        Debug.Log("main cam has " + CamMain.stereoTargetEye);
    }

they did not change at all in the inspector

ive switched all the settings between multipass and singlepass many times over, and looked through as many other people with this issue as possible without finding anything that worked

[balmy gust]

Might it be that its not intended to render two cameras for two eyes as of syncing issues and motion sickness?

[undone meteor]

and i have found a few pieces of documentation telling me i should be able to turn it left and right as well

[balmy gust]

but I am by far no expert in VR .just guessing common sense 🙂

[undone meteor]

well the setting is supposed to be there, and there were other examples i saw of people testing out whether each eye works by rendering different objects with each camera

yeahh i getcha,
this is an issue ive been going at for a few days now with no luck, and if anybody actually knows anything about this, sharing would be greatly appreciated

[balmy gust]

https://docs.unity3d.com/ScriptReference/StereoTargetEyeMask.html should have those , right?

But your isnpector is only showing both?

[undone meteor]

None and Both

[balmy gust]

Is it URP, HDRP?

[undone meteor]

the code lets me run it, and i have the variables linked in

URP

running unity 2020.3.30f1

[balmy gust]

Did you try default pipeline instead of URP?

[undone meteor]

https://developer-global.pico-interactive.com/docs/unity/en/13136/unreal-xr-sdk-faq1/
theres also this suggesting the same

hm

i dont think i have

i think ive been on urp because of a previous method of trying to acheive the same effect

ill try remaking the project in the default pipeline because im not too sure how to grade back down

wait actully might be easy

YOOO

[undone meteor]

you have just saved my project, thank you very much

[balmy gust]

You are welcome 🙂

[smoky wedge]

so i need some help, my game was working fine on my quest for a while, but suddenly when i try to load it up on the quest today, (my new build and my old builds) they get stuck on the 3 dot loading screen forever

any ideas as to why this could have happened?

[pine bison]

Use logcat to see the log when that happens

adb logcat -s Unity

[wet olive]

heyy i need some help my quest 2 link is show the eternal dots of misery could someone hop in a call and help me fix it pls

[north path]

When?
When starting the game? When going into link? Already updated drivers and restarted your PC?

[wet olive]

ive restarted and im just updating my nvidia

it happens when loading link

im using the kiwi design link cable

and ive followed their instructions to the letter and ive reinstalled my oculus app

[wet olive]

.

[north path]

I guess contact oculus/meta support for that. Not really a unity issue.
Also try different USB ports maybe?
Or a rando usb c cable to check if it's the cable

[wet olive]

i tested the connection the cable is fine and oculus support are being idiots

[north path]

It being fine with regular data transfer and in VR is different

Been there, done that

Gotta rule out each part

[wet olive]

ok lemme check

[wet olive]

nope nort the cable and all my drivers are updated and ive tried every port on my computer

[wet olive]

i fixed it the ovr server was shunting all the processing to my low power graphics card instead of my 3070

[twilit mica]

What is the difference between Device and Floor?

[somber salmon]

Hi, what sw could i use to debug oculus device

[icy mantle]

Can anyone tell me, what those Plug-in providers are and what it does? Im new to XR in unity

[north path]

With 1 the eyes start ar the camera position, with the other the camera position is seen as where the player stands, so it will increase the height of the camera (not confirmed, that's what I thought it did)

A quick google search gave this result: https://docs.unity3d.com/Manual/configuring-project-for-xr.html

[north path]

What do you mean?
You can just enable debug build and enable autoconnect profiler?
Or use logcat

[north path]

There are a few you gotta know:

• OpenXR:
  Cross platform plugin which supports all VR runtimes (steamvr, oculus, windows mr)

• steamvr:
  Well, steamvr only, so you get SteamVR exclusive features like index knuckle per finger tracking (other than that idk what)

• oculus:
  Oculus runtime only. Gives oculus specific features, but afaik most of these can be used with OpenXR already.

My personal advice:
Use OpenXR as runtime onless needed otherwise for PCVR

For oculus quest select oculus in the android tab only. It has some performance settings that can be nice. You can still use OpenXR for PCVR (:

[lime bone]

Hiya, I’m currently workin on an avatar for Vrchat and I came across this error and it won’t allow me to use the builder in the VRCSDK. What do I do?

[north path]

That's a VRChat issue, not Unity. Contact their support for a proper answer

And read the requirements for the avatars properly. Probably missing something or a bad export

[icy mantle]

thank you so much man!
One more question: so this PC tab is, that i run my application on PC and it gets streamt to the headset, correct?
and if i wanna run my application on the headset (without a pc) i have to install the anroid module and select openxr in this tab?

[north path]

The PC part is correct. OpenXR works with oculus link/pico link as well, since that runs in oculus or steamvr runtime

Are you just developing for meta quest (2) or also other standalone devices as well?
If just oculus, in the android tab you can select oculus to have those extra performance optimizations. OpenXR also works however, so this might be faster if you make your own VR system. All other systems support all platforms so that shouldn't be an issue

[icy mantle]

Id like to develop for multiple headsets. it doesnt really matter which (except it has to be oculus, because i got quest 1). right now i chose in the interaction profile valve index controllers, htc vive and valve oculus

so i guess id like to develop for them

[north path]

Do you use XR Interaction Toolkit or something else? @icy mantle

I'd say just get started with OpenXR. You can always add support for other devices using that since new devices should work with it :p

[icy mantle]

yea im gonna add it soon

its just a little project for university, and id like to support multiple devices (because we have to pitch this project as well)

[north path]

Sick

Then OpenXR can be an interesting subject to talk about support wise

[icy mantle]

ok, and this XR interaction toolkit is also built, that it would support other controllers? then this would be perfect @north path

[north path]

Yepp

Maybe check out the Unity Learn VR Pathway

[icy mantle]

ah i see, ok thank you very much man, u really helped me clearing things up

[mild igloo]

Any of you guys know if there is a way to the the speed of the VR controller. I tried the OVRPlugin but can't find anything usefel

useful

[buoyant jolt]

Depends on what VR framework you are using. But you can track the current position, the last position, and the time of the last frame - which will tell you the meters per second

[mild igloo]

private void FixedUpdate()
{
previousPosition = transform.position;
}

private void Update()
{
    Velocity = (transform.position - previousPosition) / Time.deltaTime;

    float rawVelocity = Velocity.magnitude;

    fwdVelocity = Mathf.Round(rawVelocity * 100) * 0.01f;

    currentPosition = transform.position;

    if (currentPosition.z > previousPosition.z)

Yes 🙂

You maaaay want to move that out of FixedUpdate, as that runs on the physics cycle, and won't be in sync with the visual display.

You also may want to switch from positions to localPositions, otherwise your directions may be incorrect when the player teleports or moves or spins around their play zone.

[buoyant jolt]

private void Update()
{
    Velocity = (transform.localPosition - previousPosition) / Time.deltaTime;

    float rawVelocity = Velocity.magnitude;

    fwdVelocity = Mathf.Round(rawVelocity * 100) * 0.01f;

    currentPosition = transform.localPosition;

    _direction = Direction.None;

    if (currentPosition.z > previousPosition.z)
        _direction = Direction.Forward;
    else if(currentPosition.z < previousPosition.z)
        _direction = Direction.Backward;

    previousPosition = transform.localPosition;
}

What could be a reason why a piece of code works just fine in unity, but does not work after build?

[atomic badge]

Unsure if this is the correct channel to ask but here goes

I'm working on a script which requires me to read inputs from a Quest 2 Controller

I have a bunch of public InputActionProperty where i set the input Actions

Now the problem is

When i Manually add the action and the binding , the script won't read the value.. (Bottom 2)

However if I use reference and reference actions defined in the Unity XR plugin Asset.. it works.. (Upper 3)

Even though the ones I set manually and the ones in the asset are Identical

Why is that?

For now I'm getting around the problem by adding all the buttons i need in the existing Input Asset.. but I would still like to understand this problem

is it my fault or unity's fault

[pine bison]

That could be a lot of different things. More details are needed

[zenith pasture]

The entire script? Or is the general idea of it enough?

[north path]

The more specific, the easier we can help. So the script @zenith pasture

[zenith pasture]

sorry for the delay,
https://gdl.space/exacayikob.cs
https://gdl.space/hutululawu.cs

1. is supposed to read a color from a gameobject, 2) then applies it to whatever it is on

[zenith pasture]

this is what said gameobject looks like

[north path]

And what doesn't work exactly?
Already tried adding debug.logs to all values to see where it goes wrong? (Then make a debug build and use logcat to see logs)

[storm ether]

is having alot of 4k textures effect the performance in VR or it just increase the game size ?

[zenith pasture]

In unity everything works alright, in build the colors don't change

Haven't tried debugs in build yet

[north path]

Both
More pixels == worse performance

Especially on the quest GPU bandwidth is limited

[north path]

Then try that and see where it breaks (:

[zenith pasture]

I will try to get logcat working

[crisp pivot]

anyone dealt with controller vibrations on oculus?

installed oculus package to my project, included this line to my code but nothing happens (the code is being run every update)
OVRInput.SetControllerVibration(1, 1, OVRInput.Controller.All);

[polar valve]

Unity 2019.4:
I'm hitting a crash that seems to only occur when VR is enabled. callstacks attached

This only seems to happen when I'm using a lot of rendertexture cameras (the game has an external camera system, think lots of security cameras that are all rendering the scene separately). I assume I'm running out of some kind of resource but I have no idea what.

[severe saffron]

you might just go ahead and start limiting how many of those cameras can be active at once

stagger their updates so they arent doing it the same frame. Try using less RTs and use viewport rects to pick where you wanna draw

I think you might be better off with 1 camera that hops around, and draws to a single larger rendertexture instead of a bunch of little ones

(you'd have to test this is actually better though! I'm guessing here :P)

@polar valve

[polar valve]

yeah, that will be the hacky bandaid if I can't figure this out :/

or more likely, timeslicing them between frames so only N can update per frame

[wet jewel]

Hey anybody knows How to make a whiteboard, marker and eraser; other than this tutorial, experience was not so good and I really don't know how to make an eraser.

[zenith pasture]

found the exact line that causes the issue, it is this:
Vector2 pixelUV = raycastHit.textureCoord;

for some reason it always returns (0,0) in build

but not in unity

[pine bison]

Make sure you have read/write enabled on the mesh import settings

[north path]

https://answers.unity.com/questions/1811323/why-in-unity3d-raycasthit-texturecoord-always-retu.html

Check colliders and check if mesh and texture have read/write enabled

[zenith pasture]

thanks, so the read/write is the issue, but I dont see a way to change it...?

[zenith pasture]

Can I only change it when importing it and not later on?

[north path]

In the texture and model settings its an option

[north path]

Can you confirm the code actually runs?
Is it using oculus link or quest native?

[zenith pasture]

where? am I missing something?

[north path]

The model, not mesh, sorry
and texture

Not sure if it will fix it but worth a shot

[crisp pivot]

Its link and i know it runs because the method that executes that piece of code, also returns a value right after to make the rest of the code work

[north path]

Do you use OpenXR or oculus in xr management?

[crisp pivot]

Pretty sure its openxr, i can confirm when i get home

But i did install oculus package

[north path]

Then make sure oculus features are enabled in the settings of OpenXR

OR (the better solution) use OpenXR for the rumble, so it runs on all controllers and not just oculus ones

[north path]

That's fine

The package is openXR compliant

[crisp pivot]

Ill try those 2 when i get home

[zenith pasture]

seems like the texture has it, but I just cant find the model, lol

thanks anyways, at least I know what to look for now

[north path]

Hope it works. Otherwise google 'raycastHit.textureCoord returns zero'

[zenith pasture]

spent a good few hours on this, happy to finally know where the issue is and (hopefully) how to fix it

thanks for help

[north path]

No problemo :P

[pine bison]

What file type are you using @zenith pasture? Cause you don't have the option with GLTF

[zenith pasture]

I was given the project to debug it, so I just contacted the person who sent it to me to fix it and send me the updated version

Im the code person, he´s the model person

but I suppose they should be all FBX´s

Hello,
I have a question. When I am playtesting my VR unity project, the game has less FPS inside the headset,
But if I peek from under the headset and look at my laptop screen, The Game is running VERY smoothly in the Scene as well as the game windows

Is there some setting i'm missing or what could be the issue?

I am using Airlink to playtest

I don't have a link cable, though I do have VR Desktop (Unsure how to set up playtesting through vr desktop)

[north path]

I think Unity limits fps when the headset is not in use. If I place something in front of the headset so the screen goes on it does play smooth

Maybe file a bug report?

[crisp pivot]

oculus features were enabled (still are) and i cant find any documentation on how to use OpenXR for rumble
can only find requests and people not being able to use ramble

[atomic badge]

no wait i think i didn't explain properly

Inside the Headset I get Low Fps / laggy
But in the Unity editor window everything is smooth

Its like.. The Game IS running smooth

but the headset is displaying with skipped frames or something

[pine bison]

It is very possible your airlink connection is bad

[atomic badge]

Possible, though I am able to play boneworks and other pc games smoothly

without any issues

[north path]

Check the profiler

[pine bison]

It's enough to enable the stats button in the game view to see the FPS there

[atomic badge]

I.. don't know how to do this >.<

nvm i am stupid, I thought you meant In the headset

you meant in the editor window

[pine bison]

Yes

[atomic badge]

The fps seems to be capped to 30fps..

[atomic badge]

Well it seems my project as a whole is capped to 30fps.
though for some reason it feels smoother on my laptop screen than in my quest 2 headset.. (Might just be a visual thing between hardware???? idts but maybe)
In any case.. The target to reach should be 72fps but i'm unsure what settings to change and knobs to turn to achieve this

I've tried fiddling and doing the following :

1. Turn off Vsync in project settings>Quality
2. Add this line of code to the Start Function of an empty gameobject

QualitySettings.vSyncCount = 0;
Application.targetFrameRate = 60;

I am using URP

[severe saffron]

1. shouldnt that be 72 not 60?
2. If using oculus integration you can set framerate through ovrmanager

3. I think unity XR also has a way to set the framerate but all I know is that for VR, application.targetframerate isnt it

@atomic badge

in any case 30 would be really uncomfortable in VR but would look normal video on flatscreen

[atomic badge]

I am using unity xr, and yup it should be 72 not 60 my bad

in either case the fps seems locked to 30

[atomic badge]

any idea on where to set this?

[severe saffron]

which unity version?

[atomic badge]

I am using the XR Management plugin with OpenXR

This is my installation

[severe saffron]

https://docs.unity3d.com/Packages/com.unity.xr.oculus@1.9/api/Unity.XR.Oculus.Performance.htmlv

[atomic badge]

:(

page seems to be missing

[severe saffron]

 
if (Unity.XR.Oculus.Performance.TryGetDisplayRefreshRate(out var rate))
{
    float newRate = 90f; // fallback to this value if the query fails.
    if (Unity.XR.Oculus.Performance.TryGetAvailableDisplayRefreshRates(out var rates))
    {
        newRate = rates.Max();
    }
    if (rate < newRate)
    {
        if (Unity.XR.Oculus.Performance.TrySetDisplayRefreshRate(newRate))
        {
            Time.fixedDeltaTime = 1f / newRate;
            Time.maximumDeltaTime = 1f / newRate;
        }
    }
}

[atomic badge]

woahwoah woah what is this

[severe saffron]

sets to max hz, defaults 90

[atomic badge]

should I just plug this into a start function smoewhere?

[severe saffron]

I believe so

[atomic badge]

hmm let me try this

[severe saffron]

seems like there has been 3+ ways to set fps in the past

so if it doesnt work we'll try the next thing 🤣

[atomic badge]

by all means >.<
i just want to understand why this is so convulated and how to fix it

brb need to get headset and test

seem to be getting an error

it seems .max is not a valid thingy

[severe saffron]

lets make it shorter then

if (Unity.XR.Oculus.Performance.TrySetDisplayRefreshRate(90))
    {
        Time.fixedDeltaTime = 1f / 90;
        Time.maximumDeltaTime = 1f / 90;
    }```

oops put 90f

actually the int is probably fine

good luck lol

[atomic badge]

^ yeah got the problem

using System.Linq; had to do this

at the top

[severe saffron]

ah

[atomic badge]

testing now

[severe saffron]

🤞

if this doesnt work might have to make sure unity's using the right gpu or profile the scene

¯_(ツ)_/¯

[atomic badge]

Ok while I notice the difference in referesh rate.
I can still see my Hand Controllers Jitter

and the view too when i move my head around

the jitter isn't there in the Unity Editor window, only when i view through my headset

[severe saffron]

you said you're using air link?

[atomic badge]

Yeah

[severe saffron]

hard wired the pc to the router?

[atomic badge]

Yup, it works perfectly when playing pcvr games

[severe saffron]

is the editor view visible?

do you have a gameobject selected?

deselect and maximize gameview

make sure the inspector isn't visible/updating

[atomic badge]

ok lemme try

Oh my god

That was it

THAT was it!?

[severe saffron]

the editor is known to be a lot laggier than a build but it also highly varies depending on whats selected

yes!!

[atomic badge]

How is the UI causing LAG?

what the heck

[severe saffron]

it updates every tick

its very laggy lmao

[atomic badge]

First of all, Thank you so much

Second of all, WHAT?

🤦‍♂️

[severe saffron]

yep I am used to maximize on play

def check that box

[atomic badge]

Idk how to feel about this internally
