[fossil thorn]

like, my hands are easily going through the floor the height is that small

[short nova]

Yeah, so Device mode is essentially using the device as the 'source of truth', so if you want the ground to be a specific height, you will have to set a Y offset to simulate where the ground is.

[fossil thorn]

this seems like a better thing for me. Im making a uni project right now and im making it a seated experience. So device is the best for this then?

I swear the floor mode was working for me before which is quite interesting to be fair

[short nova]

Yeah, device mode will make it easier to control the height off the floor so in-game you can provide a menu to adjust the floor height for people who want to stand.

[fossil thorn]

Ill deffo just use the device mode then. Legendary. Thank you for the help

[short nova]

Floor mode *should *work fine if you are playing to the actual device in editor or for an actual build.

[short nova]

No problem, happy to help. Good luck! 🙂

[fossil thorn]

this is using floor btw . as you can see, im legit on the FLOOR lol

this is me sat in my chair

so yeah, i think device will be the goto for me

[short nova]

Interesting... what device are you on?

[fossil thorn]

meta quest 3

doing pcvr with a cable into my pc

[short nova]

I'll take a look at it on our side as well, see if we can replicate this. Floor mode should put you at the correct height. Is this through Oculus/Meta client or SteamVR?

[fossil thorn]

Oculus/Meta client

i just click the play button in unity while the headset is on me

no steamvr involved.

[fossil thorn]

Hello, me again. Im trying a teleportation anchor, when my ray from the hand intersects, the mesh of the thing that im using to teleport to is showing at the end of my ray, making a weird duplication effect

Also the ray flickers between colours of being in the thing and not

as you can see with the mesh being shown at the point of the intersection

[pallid sundial]

excuse me, do you guys know how to make the graphic of the build apk a lot more sharper? I have an issue where between debug mode and build mode, there's a gap of the resolution. On debugging, the graphic is okay, but on building the apk and then run it, theres significant changes

[buoyant jolt]

You are probably testing in a higher fidelity graphics mode (check the Project Settings > Quality tab) instead of the mobile one. But even then, I've found there is always some kind of trade off, as the Quest 2 especially kind of does funny things with textures and it is an Android device at the end of the day, and has some limitations to it. But it is hard to say without seeing more of your settings and how much of an issue it is

[pallid sundial]

this is the setting ive implement

im gonna show you how it looks in build mode (.apk), wait

if you look at the window, its kinda wavy

at the last seconds

[subtle nest]

hi!

im curious how you would manage focus states within ui canvases ( like knowing if a certain canvas is active and if you tap anywhere else, you hide it )

[visual junco]

^could anyone help

[pure olive]

zbr the character doesnt have any rigidbodies attached to it? if so, make them kinematic, so they dont move

[visual junco]

So I go on the model and add rigid body to it? Or??

[pure olive]

nah nah don't add a rigidbody; i thought it might have one because if your model is falling then I'm assuming it has gravity/physics, which is what rigidbodies do

actually though looking at the tutorial, what your character is doing might be normal. when in play made and he has "fallen", grab the character or root bone (often hip), and try moving him around and see if he works properly

This is currently how I'm handling left/right inputs for an interactable that could be used with either hand, and it's kinda messy.
Is there a better, simpler method, or is this going to be good enough?
https://hatebin.com/clqkwnmpgo

[visual junco]

Alright then if so, how do I make it so it stays straight up because if it keeps falling down it kinda makes it difficult for the player to actually play the game.

And it’s so confusing because in valem tut this isn’t happening and idk why for me lol😭

[pure olive]

ah nvm i can probably just do something like

triggeractions[]

update
 triggervalue=triggeractions[hand]

which should be clean and effective enough

I'm not sure; maybe try,
in the root character there should be an animator component with a pre-assigned avatar
try removing the avatar, so that you still have an animator component but it is empty

[visual junco]

@pure olive has it ever happened to you??

[short nova]

Can you also check your XR Origin component in the main XR Origin rig? There is a Tracking Origin Mode that might be set to Floor instead of Device. Changing it to Device might help lift the head object off the ground and create a better starting position for your IK driver to work from.

[visual junco]

yep its already on device. its so strange. been following and everything working it just goes down (the model) and messes the legs

[short nova]

Does it move instantly or does it fall down with gravity?

[visual junco]

as soon as i press play the model instantly goes down. its as if its point was set there.

[short nova]

Do you have a Camera Y Offset set on the XR Origin?

[visual junco]

on the xr rig or my player model

[short nova]

xr rig

[short nova]

Okay great, and what about the Camera Offset object that is a child of that one? Does it have a Y value set?

[short nova]

You might make sure it's set to the same value while testing in editor, just to make sure the 'head' is off the ground

Hmmm.... when you hit play, can you see where the main camera/head is in the scene? Is it also on the floor or in the air where you expect it?

[visual junco]

wait yk what my probllem is correct?

just making sure we are both on the same page

[short nova]

Yes, the IK model is crumpling to the floor

[visual junco]

oh ok ok!

[short nova]

I'm just verifying that if the IK head is pointing to the main camera object that the camera is actually in the air, not also on the floor

[visual junco]

for the xr rig the head is in the air

when i press play

[short nova]

Okay, so what does your IK object configuration look like for the head? How are you getting the pose data to move it?

[visual junco]

when im looking through the Human model armature, i csnt seem to find the head part of the model...?

but i got a head ik

so nvm

[visual junco]

if this doesnt help let me know where to go and i'll take a screenshot and send it

[short nova]

Is there a component that drives all of the IK values? Can you send a screenshot of that?

[visual junco]

that controls all of it

[short nova]

What about the VR Character IK object that is the parent of that?

[short nova]

I see... do you know how the XR-specific transforms are mapped into the IK rig? It looks like there is an IK Target Follow VR Rig script on that last image that might reference the actual transforms it follows. Either that or it's in the foldout under transforms for the Bone Renderer

What asset does this VR IK Rig come from?

[visual junco]

i think i got it by the animation package or soemthing

@short nova rememebr i was watching valem tut. so the info will be way better tan me telling you most likey

just to let yk

[pallid sundial]

anybody have a solution for this?

[north path]

FinalIK has a solid VRIK system, worth checking out for sure!

[visual junco]

Waiiit what

Your model works for it

It doesn’t just crumple down ?

[north path]

Ive gotten it to work with some characters yeah

[gritty heart]

It’s because when you debug on link you’re running on at a higher base resolution. The default is more than the panel resolution. On a native build the default is lower than the panel resolution. You can adjust the render target resolution and raise the super sampling levels to compensate for this, at the cost of a hefty performance premium.

[visual junco]

Hiya. Do you know why my player model falls down when I press play. Like it goes down instead of standing up straight

[gritty heart]

Sorry I can’t say

[visual junco]

Oh man

This sucks

Idk what’s happening

[buoyant jolt]

I'd check that you have colliders on your floor. The new XRI has a character controller which will move with physics

[pine bison]

Anyone here used the Unity terrain system on Quest? We're loading a scene with terrain from an addressable package online, and the terrain loads, but the terrain collider doesn't work. The same scene runs on Windows when we test with Link

[visual junco]

my floor has a mesh collider

[orchid jolt]

Have you tried making a new project with just the bare bones to see if this still happens? Like just the XR origin and IK body and a ground plane?

[visual junco]

No. What happens if it does still happen or not

This is so strange. Haven’t seen it happened to others

[tidal sigil]

Hi, im currently trying a little something. The thing is: I want to use the Quest 3 (using meta xr sdk) as a fixed screen. No position tracking, no rotation tracking, nothing. The "no position tracking" part is easy, its just a checkbox in the OVRManager but the "no rotation tracking" part seems to be different. If I disable rotation tracking using code in the OVRManager I can still move my head, the game just doesnt render outside the "0 FOV". ChatGPT also doesnt really help. Any Ideas? (Please ping me if you have)

[summer crypt]

Hi, is there an event or anything where I get notified when the recenter was executed on any VR/XR platform. I'm using OpenXR and also using VR and AR with Quest 3 and also support other VR platforms. The goal is when a user executes the recenter that the player is also placed on a certain spot again so we don't have to implement an extra recenter button.

[scenic scroll]

Why? At this point why even do VR?

If you want a "fixed screen" effect with VR, you can put a canvas element as a child of the HMD anchor so the canvas will perfectly follow head rotation

However, disabling HMD tracking entirely really defeats the entire point of VR (in my opinion, at least) and can cause osme serious motion sickness

[tidal sigil]

its a nice and big screen strapped to your face :) the motion sickness part is a huge point, but i dont intend the player to move (sitting stationary)

[scenic scroll]

Are you trying to port an existing consol game to VR or something?

[pulsar verge]

Hello, shader appears as magenta color on vr(quest 3 multipass) but are fine on the unity editor

[scenic scroll]

You might even want to consider an AR/MR solution that anchors your screen like a TV in the room

[edgy schooner]

Hey, what's the best solution for fast moving collision detection? I'm doing a golf game and can't get consistent collision between golf club and the ball. I've tried

1. Distance check - nope, club movement skips the threshold distance
2. Rigidbody and colliders (continuous dynamic and box collider on club face + continous and sphere on the ball) - works meh, and only when the colliders are big enough, which then registers hits when swinging near the ball. I've tried basing the coliders size on velocity magnitude and this works between some velocity range but not super fast movements since the collider gets super big, and if it's smaller then it won't register at all..
3. Raycast and Boxcast - same thing, it will either skip the detection or hit if I make the collider big enough, which again works up to a point since for super fast movement you need super big collider and that is too noticeable. Also tried making the box/ray cast longer the faster you swing . But I think it doesn't work
4. Changing the fixed timestep to something like 120+ fps also didn't help

There is this other VR golf game, where if I swing as hard as I can, it will always detect the hit and I'm wondering how are they doing that.

How would you try to solve this?

I only care about consistent and somewhat precise collision detection. The actual ball force or direction afterwards is something else

[visual junco]

does anyone know why my model does this as i press play. its been like this and i still haven't figured out why. I've been watching Valem Tut on "Complete VR Body Setup - Arms and Legs IK with Hand Animation" and with the legs or body i dont even know it doesnt keep it up and just does the slpitd

[scenic scroll]

just a thought, but why not store a series of transforms each frame snapshotting the current gold club head position and then you can interpolate between the transforms to see if the ball was between them

dont even need scale / rotation so it would just be a list of float3

[gritty heart]

I recommend doing a sphere or box cast and using the previous frames position to the current frame position. You’ll sweep through the delta between frames and catch everything.

If the delta is below a threshold like 1mm, you can do an overlap sphere

[visual junco]

hi. quick question. so someone made the human model for me on blender and made cloths for it. but fo you know it isnt like attached properly to the model when i add it to the unity scene

or anyone

[visual junco]

nvm

i just dont know why my model is doing the splits man

[narrow briar]

not VR related, ask there #🔀┃art-asset-workflow

[spark quartz]

Hi
This question has been asked before but i cant find any offical documents from Meta about it.

Is it Not possible to live debug in Unity for a Quest 3 Standalone App on a MacBook with a M2 Chip?

That would make the developement on Mac pretty much unusable and just pain

[cosmic pilot]

When putting on my oculus headset my game view becomes grey and I get the following error.

UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)```
I am on urp and using post processing

[pine bison]

Since Oculus discontinued support for Mac years ago, no it's not possible

[spark quartz]

They dropped the support? Why can i still get the developer hub for mac? https://developer.oculus.com/downloads/package/oculus-developer-hub-mac/?locale=de_DE

[pine bison]

Dropped support for Link I mean. The developer hub is a different program

[spark quartz]

i see thanks.

Does it make a difference for developing a standalone app for the quest 3? Like could i use the link on a windows maschine to live debug whats happening?

[pine bison]

Well. You can use oculus link on windows to run the game directly in editor. This means you can test interactions and features. But it’s not representative for the performance you get for a standalone build, so you still need to build regularly to keep an eye on the performance

But yes it definitely speeds up iteration a lot

[spark quartz]

i see
but the functionallity/feature set itself is the same for when testing it in the editor vs running it nativly, right?

[pine bison]

Yes

[visual junco]

No it is. Even other people were trying to help me. You just gotta go back

[edgy schooner]

my god, thank you, I feel so stupid not thinking about this. I literally just reversed the boxcast to be in direction of last frame position and it works like a charm

[stoic olive]

im getting this error alot could anyone help me out?

[buoyant jolt]

You need to look on the console for details, that's just a generic error

You'll see a bunch of errors in your console log, and you'll want to find one that has a bunch more inside the body of the error. The real error is inside there hidden away

[untold grail]

To elaborate on what the previous poster says, if you can't see the console for some reason, you can find it under Window > General > Console

[lusty gazelle]

Hey does anyone have any good ideas to speed up air link on a meta quest 2? Trying to start XR design in unity and spend 8 hour just trying to make it not laggy enough to work, ended up getting a cat 7 ethernet cable and fixing the camera, and it worked, after 8 hours of hell i got the controllers movement, not buttons and the XR orgin camera to work, but , i run a 1650 laptop with 32gb of vengance ddr4 and a intel 7 the fact that its literally not compatble makes no sense to me as a 1050 can run it atleast lmao, anyways how to i speed up airlink? Cause it eithsr that pr buy a desktop..

[orchid jolt]

Can you not get a link cable?

[lusty gazelle]

Thats the thing, brorrwed my buddys doesnt natively suppoet the graphics card

Its a 1650? Should be supported right lmfao

But air link just barely works

We checked the graphovs card list and it was on there, its like a 800$ laptop and no matter what u tell me man i dont belive ots a "hardware" issue they black that shit with software 100%

Like dude when i tried to connect it via cable that shit was so laggy and broken It ACUTALLY FUCKING DIPLAYED VIA CABLE (non supported) for like 3 seconds e9th really laggy interaction then 8 hours of trying to get that display again only to realize that the orgin camera stopped displaying fixed that after 2 hours then realizing IT WAS THE FUCKING INTERACTION TOOLKIT or some shit, ave mever wanted a train to come hit me so badly befoee

But im stuck on airlink, if im ever gonna avutally use that pc to work on stuff it atleast needs to be smooth, which it is for 5 minutes then the wifi just outright dies, no fiber but i have a ph9one in and internet in both going to my router so max speed i can get there cat 7 cable

LIKE WHAT DO THE UNITY GODS WANT ME TO DO FFS😵

So assistance before possible self seppuku would be nice lmfao😅

Oh and wifi doesnt die, it just gets so close to diying youd think it its going into cardiac arrest so.

[orchid jolt]

You could try virtual desktop that seems to work for me

Airlink is very buggy but Virtual Desktop is the smoothest

Although working in unity kinda sucks tbh using that

[lusty gazelle]

Theres nothing that uses the casting part of your vr? Like being able to run the stream on one part and run the controls on another server

Eh probally not ill just have to se what peoole come up with

I just dont wanna drop 25 on vd if i cant use it for vd amd its still laggy yknow

Unity

[orchid jolt]

Ya thats really strange, so why dose the link cable not working? Does the oculus app say it dosen't work or something

Also what cable are you using

[lusty gazelle]

Ye the occulus app says nk native support

[orchid jolt]

Because I would try to get the link cable working as that would proably fix all your problems

[orchid jolt]

What's NK?

[lusty gazelle]

My buddys works for his quest 3 on his pc

Its my cockblocked graphics card

No

Nk is no lol

Ye it told me no native graphics card support, but i can use everything through air link?

[orchid jolt]

The graphics card should work, because I have a 1660 super and it works just fine

[lusty gazelle]

Kinda bull lmao

Nah i got a laptop 1650

[orchid jolt]

I feel like that should work

[lusty gazelle]

So i basically buy a desktop or suck metas cock for better airlink lmaoo

Not much options

Nah man it doesnt!

[orchid jolt]

You could try virtual desktop and see if that works, if not just refund

[lusty gazelle]

We went on the offical meta card its lited there as unsupported

Ye i guess

Waiting 9n payday after dropping 60 bucks on a 50 ft fucking cord

Fucking living room routers

[orchid jolt]

Or you could use the XR simlator when building the game and testing then just build it every once and while to test

[lusty gazelle]

Ill have to get some info on that i mean i never heard of the sim an i could use it but i like the visual debuging and edits you can do in vr

Basically see your code in reality right

Kinda silly a 1050 will support but a laptops 1650 wont, man no was its "hardware"

Gotta get somone to explain it to me cause i dont get thaf crap

[orchid jolt]

I actually really like the XR simulator, it's nice for just small tests when you don't want to put on the headset

I would also try reaching out to meta support

[lusty gazelle]

You got thier contact? Out and about atm lol

[orchid jolt]

I would just use this https://www.meta.com/en-gb/help/support/?g1=5677250625703607&g2=5699619870136632&g3=none&et=none&sg=skip

[lusty gazelle]

Much appreicated

[lusty gazelle]

Is there like a stand alone xr simulator app for oclus on sidequest or somthing? Be pre sick if somone made that just cloud upload the code and assest and play on a standalone

Messaged oculus lmao not sure what the reply will be tried my best to not sound pissed and tired after a day of hell

[orchid jolt]

I don’t think so because for it to run on quest standalone it needs to be an .apk file, so you would have to build the game every time you update something which would take forever

[lusty gazelle]

Awe shit

Could make somth8ng that ports a unity file directly into a apk?

Or run it through a emulator make it like a gameboy game or sum shit lmfao

[pine bison]

You need to build either way, so why not just build and run?

[lusty gazelle]

Guess so all im trying to do is get the actual vr game stream all the cod8ng and all the "funn" stuff i do directly on pc

Only thing i even want the freedom of linking to a pc is the workflow to be able to game tesy in vr

[pine bison]

That's all perfectly supported as long as you have the hardware to run it

[lusty gazelle]

I know, thought i did but apperently not

It can run through air link but rough as heck

Just word to ne how a old scjool 1050 will get the job done but not a gtx 1650 in a laptop just doesnt make senss

All im really trying to get is the stream, like of someone made a mod for the casting where it picks up the unity signal from your pc and diplays the screen i dont know what even possible but man it was dissapointing

Like 850$ laptop and thats not supported, kinda silly

Had the pc before the quest just thought it would have maybe more plugins for game dev in unreal an unity like displaying a stream i dunno just really hope theres a better way to link or display some day or it get optimized to hell

[pine bison]

That is literally what Oculus Link does

[lusty gazelle]

Oculus link? Man i got this like a week ago

I know air linl

[pine bison]

That's the same

[lusty gazelle]

But ive tried everything. Eveything man

Still runs ass

I had like 100mbps or some crap on my wifi with a cat 7 cable

[pine bison]

Windows laptops need to be listed as VR Ready to be able to run good enough

[lusty gazelle]

Makes sense

So are they just software blocking them cause thwy cant optimize the games to work on really old cards? Cause i mean a game looks crappy enough anything can run

Dont undertsand why they wont just let me run it like crap corded, it would be better than the ups and downs from ethernet or wifi

[pine bison]

No there's no software block, it just comes down to the hardware. The same applies to Air Link and your network hardware

[lusty gazelle]

Interesting i mean after upgrading the ram to vengace ddr4 32 gig i can run baldurs gate in ultra im like almost 100% sure the card could do it, i jjst dont get why it cant yknow? Like what in the hardware is limiting it vRam? Just new to all this stuff really didnt want the first night to he debugig hell where at the end of it it just. Works

Or why i cant altreast try to do it at the cost pf the safety pf my computer?

Never really understood why i cant just throw it on anways yknow itll just run like ass like the wifi stream, but mayyybe a little less and ill take that over the constant highs and lows of my wifi

Im mainly looking to work with extrmely simple low polly models and put all my work into a phyisics engine based on the bonelabs one and just add on to it continuously

So why i need to be able to run the graphics if im onky usuing like 25% of them

That i dont get, shouldnt hardware limitations be based on what ur computer can run? Even like ass? Instrad of just not running atall, i mean then atleast that gives the community the ability to optimize it for thier ass pc

Dont get it man, donr think i ever will

[visual junco]

Please. does anyone know why my model just goes down as soon as i press play. ive been trying for a days and idk. ive tried re doing it constantly and im watching valem full body vr tut

[orchid jolt]

Have you tried a different model?

[visual junco]

so i got two off sketchfab and i went to mixamo so it can rig it. do u think it can be that?

[orchid jolt]

Maybe, I would try like the defualt model that comes with Valems tutorial, or find one on the unity assest store

[visual junco]

kk let me try

[visual junco]

@orchid jolt yeah man idk now. its happening with even models from the site valem used? what the hell is going on man

why does this have to happen lol

[orchid jolt]

Have you tried making a new project and just doing the IK tutorial

[visual junco]

nope

[orchid jolt]

I would try that then

[lusty gazelle]

Hey just letting you know everything working with VD puts qiest link to shame, im havint a problem getting the xr org8n and controllers to work properlly in vr desktop, it was working normally in quest link unity XR could move controllers and head bit janky but it worked, after mov8ng over to virtal desktop its almost like it changed the inputs to be able to run VD but its fucking with all the cam controls

Any ideas?

No code edited or chanfed to my knowlege, do i have to get a VD Xr support plugin? Or run it in fullscreen somehow to inky get the vr input, very new to this so paitence and help is much aprrectaied

The XR interaction toolkiy is set to use xr device in sence checked instaiane in editor is checked xr interaction is set to xri default input actions with a input and xr inteactiin monitor followed a tutoiral and like rebuilt it 4 times have no idea what im doing wrong, the controllers are moving the headset view like a mouse, think its VD and unity fighting over inputs? Dunno

[orchid jolt]

Ya VD is really buggy when working with virtual desktop I think it's cause it's using steam VR which can mess stuff up. Idk how to fix it so I am not much help sorry

[buoyant jolt]

If you are having a problem with virtual desktop, I'd contact the company selling it. They probably have a discord or something.

[ripe notch]

Hi, I am trying to create an environment that has an animation, it works correctly in a desktop version but when I use Oculus quest 2 the animation does not play. the environment is also extremely laggy. has anyone had this issue before?

[buoyant jolt]

I'd start with checking the device logs, it might just be something broken in build that was fine in editor

[visual junco]

hello. does anyone know how to make a full body vr like bone labs for example. ive got a model and its rigged but i want it to be the model for players to move around with

[hearty cobalt]

I know this may seem like a pretty stupid question but, I'm trying to make it so my character can go through a for example, a cube. I've tried turning on isTrigger in the box collider but since I think since im using VR it doesnt work the same, its for my trigger that triggers an animation. I've already set that up I just need to know how to go through a cube!

[errant spear]

Does anyone know of a video that would help out with setting up a playermodel for the XR Origin?

Looking to do a vrchat type setup with the bones

[narrow briar]

wha'ts the least broken version of unity for VR? 2022.3.23 streaming stutters at 10fps

[narrow briar]

seems to be a known problem with 2022... https://forum.unity.com/threads/is-anyone-else-getting-terrible-vr-performance-with-2022-lts-fixed.1446334/

[buoyant jolt]

2021 LTS was very stable for us. I started moving to 2022 and have us on the new version - upgrading our framework was definitely a chore. But now after all that there is a good chance the team will end up on Unreal anyway, so now started working their GDXR.

For 2022, I'd say we are hitting framerate targets just fine - but we are also using BiRP instead of URP

[buoyant jolt]

FinalIK worked good for us for rigging and avatars

[errant spear]

👌

gotcha ill check it out

[narrow briar]

in apk build there are zero framerate problem, only in stream

I was susprised how slow vfxgraph is, framerate tanks real fast. I start to wonder if URP isn't slower than a heavily nerfed unreal 4.27

i'm about to give up on convincing the team to move to unity... unreal saves so much grief in term of rendering alone

[buoyant jolt]

Yeah, I added the spline package to a project. Their sample comes with a shader that generated 65K shader variations and triggered a whole slow down on project build times. Sometimes vfx & shadergraph run terribly

[narrow briar]

haha! the spline package has a few hilarious threads on the forum. how terrible it is

I think that even the XRtk doesn't use it, they wrote their own

[buoyant jolt]

We have a big incentive to go the other way. We do non games and Unity is forcing us to Industry pricing (5k/yr per dev) due to their rule about charging us based on our clients income now... Compared to free with unreal. I'm hesitant but the cost savings is enough to put the whole team into training and still come out cheaper.

[buoyant jolt]

Yeah! To be fair, the XRTK is handy. Complexly written but definitely something I'm missing from unreal

[narrow briar]

on my end 1/3 of the team is unreal and as hard asd I tried, I'm running out of good argument, i start to sound like a car salesman

does unreal new licensing hit you with a 1850$/seat/year fee?

as non-game studio

[buoyant jolt]

I haven't played that, but I'd take a peek at FinalIKs VRIK as well. There are some other free alternatives. But full body rigging actually worked pretty well for us last time we touched it (a few weeks ago)

[buoyant jolt]

Only if you are >1m in revenue

But unity is charging us 5,000/yr/seat regardless of revenue. So I'd happily pay if I need to

[visual junco]

well i already got the a model and got it rigged. should i just watch finals vrik vid then

[buoyant jolt]

And check around, any good VR IK system should work! There are some free ones too

[visual junco]

Thanks alot!

[narrow briar]

wow! yeah no contest

[buoyant jolt]

We've also been debating some open source alternatives. Donating 1k/yr/dev would mean a lot more to them plus they would be excited to see it being used for medical recovery/teaching etc.

But I digress

[narrow briar]

you meantioned a few, hopefully you'll get the motivation and time to do that write up you were talking about

[buoyant jolt]

On the slowness topic ... if you are using URP & 2022 --- make sure you are on the latest URP. It finally has some much needed fixes for Vulcan. It was actually performing worse in benchmarks for quite a while (~10% worse), but now we are seeing a stronger boost with URP for once (~40%) which is a huge improvement.

[narrow briar]

that's the anoying part about Unity's code:

summaries on built in events - useless, adds fat to the script

[narrow briar]

damn, that's scary that things devolve on new releases... i mean ok ue5 is far slower than ue4 render wise but maybe that's the price to pay for the new goodies, even not using them

[exotic patrol]

How would I go about spawning a grab interactable object in the players hand if they interact with something? Similar to how grabbing ammo from your shoulder in half life alyx works.

[shadow ermine]

Im having this issue when I play with my vr headset it automatically shuts the program down and it gives this error

[narrow briar]

eject object, instantiate, attach... depends on how you implement interaction, really

[untold grail]

Does anyone know of some post processing that is compatible with VR?

I tried using the unity package in default render pipeline, and for some reason in my build it blanks out my left eye camera. Even if I don't have a post-processing aspect enabled, just having the package downloaded causes this.

[swift stream]

To switch between interactors, should I set related objects to Set Active False?

[gritty heart]

Why do you want to switch between them? The interaction group on the controller root manages them for you.

Also in xri 3.0, near and far are unified into the near far interactor

[swift stream]

Because the functionality of the controller changes depending on the current tool that the player selects.

[gritty heart]

Ok. Well you can just turn off the game object if you want.

If you only have one interactor at a time you may want to get rid of the interaction group

I do recommend xri 3.0 for this kind of stuff though because you can customize the near far interactor a lot more easily than the direct and ray interactors

But what you want should be doable

[swift stream]

I didn't understand benefit of interaction group when I added that.

[swift stream]

Okay thanks.

[gritty heart]

It mediates between the interactors you have in the list, by priority. Poke, then direct then far.

If something higher in the list selects, then the lower stuff is blocked. It’s also how the ray turns off when you hover something nearby.

[fossil thorn]

I want to be able to cast a ray from the camera, where the users head is looking and have that ray interact with things. How would I go about it? Just like the thing from this? https://docs.unity3d.com/Manual/CameraRays.html or is it more in depth than that

[untold grail]

I was interested in this too! I think I understand how to attach the ray to the head, but not exactly sure how to do things like give the head-ray behavior/triggers that are distinct from the hands

(I don't want my head ray to do the same thing as a hand hover, for example)

[fossil thorn]

I saw that theres a preset for gaze ray in the ray interactor in the XR section

my idea would be to do like an on hover event or something. and like count how long that has been going for and after x time, activate the thing

[untold grail]

Yeah! I'm actually doing something very similar in my own project.

Right now, I've kind of made a "cheat" version by having an invisible cylinder attached to the camera, which tracks the player's head position. So I can use it to trigger events when the player "looks" at certain objects.

Its definitely not ideal though, since it can't adjust dynamically based on distance like a ray. So very interested to hear if you get this figured out!

[fossil thorn]

I got some basic hover working

just need a XR ray interaction and then use the gaze interaction preset

and then you can use it like any other ray

@untold grail dont want you to miss it

[untold grail]

Oh thank you! I'll give this a try later

[fossil thorn]

I know you can change the ray to be a different type so it can be a cone too so it can be closer to a cylinder and also easier to use

[supple roost]

Tongue asmr

[fossil thorn]

ah crap my bad

[supple roost]

I think you can accomplish this much more efficiently with the Vector3.Dot() function, it's typically used to find out whether an object is within the line of sight for AI by checking if the value is above a certain amount. You can do this here to get your cone shape.

Looks like whatever the XRT is doing isn't too responsive or reliable, god forbid the XRT does anything right.

Just something to keep in mind if this is critical for gameplay

[gritty heart]

Theres a gaze interactor in XRI that should be able to handle this

[gritty heart]

Dot is fine but it will also report false positives for things that are occluded. My advice would be to gather targets with dot and then raycast against them to ensure they are visible and not occluded

[fossil thorn]

this is what I have found. its pretty good!

ty btw

[hearty cobalt]

I know this may seem like a pretty stupid question but, I'm trying to make it so my character can go through a for example, a cube. I've tried turning on isTrigger in the box collider but since I think since im using VR it doesnt work the same, its for my trigger that triggers an animation. I've already set that up I just need to know how to go through a cube!

[supple roost]

Yup, that's the idea 🙂

[supple roost]

VR doesn't change anything except for where the character's hands go. Don't think of it as someting separate.
You still collide with the cube when istrigger is enabled? Can you send a video?

[hearty cobalt]

ok im logging into unity right now

[hearty cobalt]

this is my trigger btw

wait lemme make a better video

[supple roost]

I need to see the components on the object you're trying to move into it

[hearty cobalt]

like the player components?

[supple roost]

Well yeah

Try to spawn a rigidbody ball, see if that goes through

[hearty cobalt]

it goes thru

[supple roost]

Then it has something to do with your player.
This is called bisecting, you will find that you can find the source of most problems in computers this way 🙂

Show me the player components

[hearty cobalt]

gorilla rig

gorilla player

[supple roost]

While you're at it, remove the box collider entirely. It's a long shot, but I want to be absolutely sure that the trigger box is the one somehow causing collisions

[hearty cobalt]

ok i deleted it

[supple roost]

Now try

[hearty cobalt]

it lets me go through it but it doesnt trigger the animation

[supple roost]

Well yeah

Okay

This is fking weird, put the collider back where it was. Now remove the XR Rig from gorilla rig and see if you can go through

Ignore any errors that might arise

[hearty cobalt]

nope doesnt let me thru

[supple roost]

Now try removing the player

Basically the idea is to keep removing stuff until it works

You saw that it worked with a regular rigidbody ball, so it's not magic blocking you from passing the trigger

One of your scripts in the rig, is somehow preventing you from crossing over

[hearty cobalt]

well it lets me through

but doesnt activate the animation, not sure if thats my fault or not tho

[supple roost]

The issue you're trying to solve right now is your character colliding with a trigger. Forget the door.

So it lets you pass the trigger without the player script?

[hearty cobalt]

yep

[supple roost]

Awesome. Go there and look for bullshit that might be causing this

Is it a monobehaviour or inheriting something else?

[hearty cobalt]

idk but my only guess is the capsule collider

[supple roost]

It is inheriting from capsule collider?

No it's not

[supple roost]

Your ball had a collider too. It shouldn't interact with a trigger.

[hearty cobalt]

true]

[supple roost]

Start removing stuff from your script until it works.

[supple roost]

I ask this because I highly doubt you accidentally coded a collision system

If its inheriting from something else then that might be the cause

[hearty cobalt]

its these two

[supple roost]

No, what does it say up top

: MonoBehaviour, or : Something Else?

[supple roost]

I mean stuff from your code, not the inspector

[hearty cobalt]

lemme check

MonoBehaviour

[supple roost]

Okay

So just start removing code

Send it to me too, I want to see

[hearty cobalt]

ok

lemme find it in explorer

[supple roost]

@hearty cobalt Dude... you coded your own collision system and you're confused why you collide with stuff 🤣

Include checks for whether the collider is a trigger or not.

[hearty cobalt]

well im going to be completely honest and say i did not code this 👍 gorilla tag open source locomotion

[supple roost]

Oh, well there we go

[supple roost]

You'll have to actually understand how that code works. So get reading, and then modify it for your purpose.
If that fails, you can make your own detector script that doesn't use Unity's colliders but rather predefines a shape in the inspector. Better to do the first, though.
Good luck.

[hearty cobalt]

[narrow briar]

@buoyant jolt might want to hold off onswitching from BIRP to URP, it's a nightmare to get streaming working: sometimes it works other times you get 5fps
might be faster in build but not worth the hassle

single screen URP is super fast so they prob broke something that made it incompatible with the oculus app that does the streaming

u6000 has zero problem tho...

but that means new license

[buoyant jolt]

Thank you for sharing - I'd be suuuuuuper annoyed 😄

[narrow briar]

aaaaand you want to heart the funniest part?

[gritty heart]

You know, in xri 3, you can make a caster for the near far interactor that works this way. I think our cone casting logic is rock solid but if you insist on dot product, it’s really easy to spin up a custom caster and do it, for gaze or controller input.

[gritty heart]

Have you filed a bug for this? It’s worth looking into

[narrow briar]

i have sent the project on a few other reports, but you can do it easily: on win10 bring in xrtk 301 in 2022.3.18 and up

[narrow briar]

got so bad that instead of questlinking i'd been iterating builds - now that i need to speed up pace i'm back to QL and noticed that the controllers stay at 0,0,0... any setting you think i missed?

bah it's working now: i toggled on/off a few openxtfeatures so here's a bug for you

(back on BIRP, framerate is so smooth)

[gritty heart]

I test with air link in the editor and my framerate is fine. I’ve done builds to Android too - no problem. I just haven’t done windows pc -> air link as a standalone build

Are you submitting the depth texture? It could be related to that

Also urp perf is bad if you have any post processing on

Or if you have intermedia mode texture set to always, instead of auto

You also have to use the low end preset which doesn’t have AO

The default Android urp settings give you tearing - it’s a know unfortunate issue

[narrow briar]

cool thanks i'll look at all these params, zero post effect, might have depth on, i'll pull the URP commit

[gritty heart]

Yeah dig through the urp quality settings

Make sure you’re using the lowest tier

And turn everything off

You should be getting better perf than with birp

[narrow briar]

i'm in fact using the default xrit 3.01 settings, wanted to take it for a spin

[gritty heart]

Xri doesn’t affect your urp settings.

[narrow briar]

build speed is fine, btw, it's airlink or quest link that's bogging, fine in unreal 4.27 so that's not the link

[gritty heart]

Grab the vr or mr template though - they have great urp setups

You should be able to clone vr template and go

It doesn’t have xri 3.0 yet though. Working on that

[narrow briar]

where are those templates?

[gritty heart]

On the hub. Just grab latest 2022.3 and they’ll be there

[narrow briar]

that's what I was using.
had to reimport the samples with XRIT 3.01 because it broke a bunch of stuff

using grip to trigger buttons is weird, btw, every game i've played and the ue ones i've worked on all have trigger to interact with buttons

[gritty heart]

Yes 3.0 is a breaking update

Well have a vr template update soon

But in the interim just use the urp settings

[narrow briar]

how do you switch to 90Hz? Application.targetFrameRate = 90 doesn't do shit

on quest 2

[gritty heart]

You need the meta quest OpenXR package
https://docs.unity3d.com/Packages/com.unity.xr.meta-openxr@2.0/manual/features/display-utilities.html

[narrow briar]

Unity.XR.Oculus.Performance.TrySetDisplayRefreshRate(90);

I like the simplification you did with v3

it's more Unity like

you only prefab what you reuse and the roots of demoscene aren't reused, only their components

this is how we organize scenes:

blaser, singlebuttons etc... are reusable, not their groupment so you don't pack them together

[gritty heart]

That’s great! I also really like the simplification in xri 3

[narrow briar]

yeah it's close to what we do

the climbing: can you explain why, when i release both hands i don't fall?

also i recommend switching all rigids to continuous and simulation mode to Update. quest 2 has enough cores to handle that and Oculus boots your app if you drop below 72Hz anyway 😄

[gritty heart]

Yeah it was intentional. It locks vertical motion until you hit the stick. It’s been on the list to make it an option to control.

Sim mode to update causes variable frame time for physics which can lead to imprecision

But I’m sure there are benefits. You can also turn on rigidbody interpolation that helps

[narrow briar]

what i'm saying is on quest you won't have that because you need to hit 72hz or your app gets kicked out

[gritty heart]

That’s true

[narrow briar]

for other targets though it's a thing so you're right, it's better to set fixedupdate time to something ridiculous like 1/100

BIRP gives me relaly solid framerate, might stick to it, you get what % boost from URP?

[narrow briar]

Thank you for sharing - I'd be

[gritty heart]

The big differences with urp:

• forward+ you can get more lights, - the Srp batcher is much more efficient than the birp one (this alone can get you some free fps)
• urp has a temporal upscaler - though I’m not sure it’s compatible with quest
• Application space warp (currently requires a custom urp)

[north path]

Debug log what is happening?

[thin pasture]

can someone help me with that

[narrow briar]

% boost?

i know URP very well due to spending a few months optimizing a game that barely ran on a 2060 down to a switch, but was warned that it tanks on quest 2 due to many new bugs since 2020

[gritty heart]

One of the big bugs was a shadow regression that was fixed. At this point it should be very useable

[gritty heart]

Idk exact numbers

[pallid sundial]

Check your scripts, there's an error. Or are you using libraries that are supposed to be used on editor only?

[narrow briar]

which version of unity+ urp doesn't stutter in quest link? on the xrik samples (keeping it simple)

[gritty heart]

Have you tried just running the VR template with 2022.3? It shouldnt stutter on link.

The stutter is from your urp setup most likely as I explained yesterday

You have to assign the right pipeline asset for your quality setting associated with your platform.

[narrow briar]

it stutters to 5fps

that's why i went back to BIRP

[gritty heart]

Honestly, something may be wrong with your setup. Do you have insane super sampling on link?

I run the VR template with URP at full framerate

over air link

[narrow briar]

it's the stock v2 template

same with v3 vrik but as you said it doesn't change render settings

[narrow briar]

🤔 what version of oculus desktop? gpu, driver version?

i think it's a urp problem because birp is smooth, so is unreal

[gritty heart]

I really don't know what to tell you

Works fine for me

Im on a Quest 3, auto res settings, tested on 2080, 3080 laptop. Latest NVIDIA drivers

[narrow briar]

you have a q2 to test?

[gritty heart]

yes Ive used it too and it works fine

[storm ether]

We're trying to make a cloud transition in VR by having clouds surround the POV of the player and transition into a new scene. How would we do that? We're following this storyboard and my team is kinda stuck on how we can execute this. Any ideas?

[analog elk]

does anyone know how I can make a script that detects if your arms are swinging and increases your speed? I haven't been able to find a tutorial that actually does it correctly and isn't outdated (like blade and sorcery running if you know what i mean)

[narrow briar]

even with latest nvidia driver 2022.3.18 bogs down in questlink

2021,2018 and 6000 are fine in urp

[buoyant jolt]

We do this a few ways, one is just a shader. One is a textured screen fader. And the other is a vfx geometry thing.

The lazy approach would be an inverted sphere with a cloud skybox. You may need to create a new skybox shader based on the normal one to add a colour. Or you could just jack up emission.

[fossil thorn]

So I have an interactable object, I want to run a script when one of its events is fired. How do I go about this? It seems like broadcast message may be the only way? idk tho

[fossil thorn]

Ah I think I found the answer. I need to make my own script that inherits from an XR interactable

[gritty heart]

Weird honestly. I still think there’s something wrong with your setup

[gritty heart]

No you can use the intersection events on the interactable. If you want to do it with code just create a script with a reference to the interactable and add listeners to its events

[white flicker]

is around 100k verts good enough for quest 2?

[narrow briar]

depends on the rest. quest GPU is unified, ALUs allocated to whatever load you send

so if you have heavy compute, 50% of the ALU might be allocated to that, leaving you with 50% of a gpu (it's smarter than this but ballpark is that), if you have post process and that eats up tons of bandwidth or many ALU for fragment stuff, same.
in other word you can't think of it in term of hard workload for vertex, frag, compute, it's all one pool that's being used

so you'll need to benchmark heavily

Weird honestly. I still think there’s

[white flicker]

got it

[lone knoll]

Either manually modify all the queries to include QueryTriggerInteraction.Ignore , or set this settings checkbox to false

[supple roost]

Hey guys. My project runs at 90 FPS in an empty scene when my headset is enabled. 700 FPS with a regular camera. What gives?

I thought that VR was supposed to cut your frames by only half 😆

[buoyant jolt]

It also sounds like vsync might be enabled.

Or the target framerate is being set.

You don't usually want 700fps in VR, as you'd just be burning up batteries on mobile VR

[supple roost]

Not mobile

well maybe

I'll see if VSync is ticked

What is the overhead? I have my own custom tracked pose drivers and don't use any of the XRT crap

[narrow briar]

something weird's going on with 2022 VR template and XR-IT. Hand controllers stop moving, it happened after switchng to 3.01 i think.
So I check the input debugger and get position and rotation in the device, but nothing from XRI Left/Position in the input map. The input debugger doesn't show mapping validity, off course so maybe something there got corrupted.
So I bypass trackedPoseDriver with just this

I think it's correct, not even sure that these need to be enabled and disabled but new input being ... what it is this can't hurt
result = nothing comes through

and for the Lolz, here's new input system in all its glory

... uh what?

you know what, i'll nuke all this and redo the input, i think XRIT 3 corrupted these inputs

i think fallback means if one input doesn't feed data the next one takes over, probabaly to handle controller vs hand gesture (although these should be the same, no?)

wow after redoing left and right controller all hell broke loose

did i do something wrong? the mapping is the same, i just removed fallback and redid the controller mapping, it should not be this brittle

[white flicker]

bumping this

still haven't fixed...

[gritty heart]

You need to replace the XR Rig in the scene, and replace the samples folder with the 3.0 starter assets. The Input setup has changed a lot

We are working on a template update soon though

[narrow briar]

i did that already.

it's an input issue introduced by v3

[gritty heart]

I think something got corrupted by your upgrade. Did you try deleting your package cache folder and doing a re-import all? I've upgraded the template locally and didn't run into your issues.

Do you have multiple interaction managers in your scene? If so that can cause issues. The referencing of the interaction manager should be automatic

[white flicker]

dont think so but will check

[gritty heart]

Also make sure youre not spawning a reference to a game object in your scene, but a proper prefab. Your issue sounds like you're calling instantiate on a live game object.

2020.3.48 empty new project with Core VR template starts with a compile error

which then gets resolved but builds fail 100%

that's before upgrading XR packages and after

although it looks like an android problem, i figured updating XR wouldn't hurt

[short nova]

Definitely looks like an android minimum API level issue. Have you tried bumping the API level in Player Settings to see if it goes away?

[narrow briar]

that?

[short nova]

yes

[narrow briar]

that's not it, and it's now broken even 2022

all the android build tools are local to the unity editor tho

[short nova]

You cannot do builds in 2022 as well? Same project or new project?

[narrow briar]

empty with vr template and same

i have a hunch about that, some of the Java SDK path needed for unreal collide

[short nova]

I can test a clean build on my end. Which version of 2022 is it?

[narrow briar]

thanks. 2022.3.19, .23 does the same and so does 2020.3.48

but hang on, i removed all Android and Java from my machine, path gone, reinstalled the USB driver ... i bet you that was a dependency, Java ... ya know

if so, that's a bug in the build, some path not being absolute to the install directory

yep, that did it

[rapid pumice]

I have a question about using the XR Device Simulator. When the controllers are not engaged in the simulator, I move with the W,A,S,D keys and the capsule collider doesn't seem to move with me. So basically, I can move around the scene without any collisions. The collider only moves with me when I have the controllers engaged, i.e., when I hit tab. Is this a bug or am I missing something?

[snow bolt]

Hey guys, I'm working in the Meta All In One package and I'm using hand tracking. I'm trying to create a darts game where you just throw darts at a dart board. I have everything set up and it's working fine but I'm not able to get enough velocity while throwing the dart. I've set the weight lower, I've removed drag, etc. Does anyone have any advice on how to make the dart throw feel more realistic?

My first idea is to apply a force to it when the hand releases it but I can't find anywhere in the docs or online how to get the throw event to trigger something like that with Hand Tracking rather than a controller.

Any advice would be appreciated.

[narrow briar]

gesture recognition lags. you can check for acceleration reversal as a launch signal instead

[snow bolt]

Is there anyway you can link me to some documentation about that?

@narrow briar what is a launch signal

[plucky kestrel]

How do people optimize URP for Quest 2? Built-in won't allow me to do an outline post process very easily.

[errant spear]

Is it worth making your own vr system or just using the xr public one

For a somewhat beginner into vr dev

[orchid jolt]

I would say use XRI. Making your own VR system can be good in someone ways but it’s easier to just use XRI in my opinion

[untold grail]

For a beginner I'd definitely start with the XRI.

It give you a lot of really nice tools and basic scripts, but it's also pretty customizable. So its is a great way to experiment without necessarily having to start completely from scratch.

[narrow briar]

Something like

if ((velocity.magnitude - oldVelocity.magnitude) < 0 && Vector3.Dot(velocity, oldVelocity) < Mathf.epsilon)
  {Throw(velocity);}
oldVelocity = velocity;

[narrow briar]

Always better to make your own but XRIT is a good start and who knows, maybe you'll be ok with its quirks.
Just know that if you need to change anything, you'll have to parse through extremely verbose code where 600 lines does this:

[narrow briar]

just be aware that the Input System is extremely buggy in non-c# mode

[snow bolt]

Right I understand this but what I don't understand is how to know when this is occuring, how does this become triggered? I don't know how to subscribe to anything like an "Onthrow" or "OnRelease" action when using hand tracking for quest. Can you direct me?

I am not using controllers.

[narrow briar]

I don't know your code, I do everything custom to avoid that sort of stuff. if you're using XRIT ask @gritty heart

[snow bolt]

I'm using Meta All In One package on the Quest 2 so it should be pretty common. I don't have any custom code.

Do you know anyone who's an expert, or at least really experienced, with Meta Unity package?

@narrow briar

[narrow briar]

you're using a framework for interaction, no idea how they handle that, @buoyant jolt and @supple roost might know

[snow bolt]

Thansk for the recommendation

[gritty heart]

Meta have their own forums to ask that sort of question
https://communityforums.atmeta.com/t5/Developer/ct-p/developer

[buoyant jolt]

We have a couple of games where we cheat the physics a bit. One specifically is for playing with a dog 🙂 it's a cute game

Anyway, for the Frisbee, I apply a temporary declining multiplier to the velocity and countering gravity slightly after a user releases it, depending on the angle they launch it. It helps make up for the lift you get from the wind. Works beautifully but you'd never know about it.

For a dart, I'd probably track the last X frames as an average out, and on release, multiply the velocity based on that average.

That'll get you a pretty smooth throw velocity

You don't want to rely on a single frame with their hand tracking if you can avoid it

Also lots to do with hand posing for the release. But in one of our monster games I just track knuckle angles. If you want to do it different, in your case, you could track finger distance to determine the pickup and throw if you wanted. But the Meta examples should show the proprr way with good reliability.

[snow bolt]

You'd think there would be an "on release" functionality haha. Ok thanks for the advice.

[snow bolt]

Tracking how far away the fingers are to see if it's held or not seems like a complicated way to solve what should be a fairly simple issue. I'll look into it.

So every single one of your interactable objects has a reference to the hands and they're just always looking to see if they're in the hand? @buoyant jolt

[buoyant jolt]

Well, you have to keep in mind, I've worked on many many projects, but only a very small subset with the Meta Quest SDK (as I like cross platform toolkits). !we used it briefly between the VRTK and OpenXR era and needed our own abstraction layer to make framework switching easier... These days I prefer the open hand and openxr. The last time I used the oculus specific SDK, I used it for a physio recovery project. And at that time I didn't have any issues getting their on release stuff out of the box.

The custom hand stuff I mostly did during our early meta quest era when their hand sdk was in its infancy

So for me, whipping up our own interaction stuff was usually quicker than doing it the proper way as it was so early on. I highly suspect you can get it out of their SDK now somewhere

Long story short I absolutely think there is a smarter way.

But for what you are doing, I'd just smoothly multiply the velocity on release.

[snow bolt]

@buoyant jolt I feel like there has to be a way to simply know when the object is being released but I've scoured the docs and googled and it's just not that straightforward 😂

@buoyant jolt I'm gonna be looking at this issue later on today I'll update when I've got a fix

[narrow briar]

In 2020.3.48 , the hand controllers are at the proper position in editor but they're offset by a bit in quest, using Input System. Any setting to correct that?
the head is correct

I use the [BuildingBlock] Find Spawn Positions component to place objects onto a table upon start. The geometry is loaded from a database, so the bounds are not known beforehand. Often the objects spawn inside of eachother or inside of the table. Does anyone have any idea for a quick fix?

[exotic patrol]

using unity open xr I get really annoying and obvious blue rings around my view on my quest 3

[narrow briar]

going down the rabbit hole... OpenXR is not 1:1 with vendor API and until recently was not recommended as it also introduced 100x latency. so perhaps that version of unity had a more 'alpha' version of it.

it's working now by switching even quest build to it

but it wouldn't surprise me that it's the cause for trigger missing events on q2 and not on desktop

(i'll end up going native, i can smell it 😆)

[crude frost]

is there an XR Interaction Prefab, that has fake hands around a generic XR controller, that animate the fingers to the buttons pressed on the controller?

[gritty heart]

You can correct the transforms in the rig and apply offsets as you see fit. The controller models have a 5 cm offset on them that you should remove if you’re using the oculus sdk. It’s the difference between OpenXR and oculus XR

[gritty heart]

Can you file a bug report for this?

[narrow briar]

we're talking at leas ta meter offset in the vertical axis, seems more like a bug, but i just swtiched the oculus build to openXR and that fixed that

thx tho

[gritty heart]

Haven’t seen that before. 2020 isn’t supported anymore unfortunately. If you spot that bug in a newer version please file a report.

Glad OpenXR solved your issue for now though.

[narrow briar]

that's too bad it's no longer supported, it's such a solid release.

[gritty heart]

Yeah I mean - Unity can’t maintain all versions indefinitely. All lts versions are supported for 2 years.

I think 2022.3 is quite solid though, but I understand if it’s too late to upgrade some old projects.

[narrow briar]

that reminds me that i need to send you guys a repro for the questlink framedrop in 2022!

#1227598076596850698 message

[old bronze]

Hey, working with Oculus quest 2,
Recently migrated the project from Mac to windows, with Version Control
Installed the proper version, with Android SDK and NDK, with all the proper set up
Plugging in the headset with USB-C cable, allowing date transfer, clicking Build

And just when its about to finish building, if fires these 2 errors
I already tried reinstalling the version, and even separetly installing the Android SDK, but nothing seems to work

any help is incredibly valuable :>

Note : I open the project with Android platform selected, but i also tried Windows

[bold parrot]

where are the a b x y buttons in the default XRI input map? I can't find them and the naming is horrendous

[bold parrot]

turns out it's not pre-created, you have to add new inputs for that -.-

[old bronze]

another Note, the last process during building, after which the errors appear is : Copying APK to device

[buoyant jolt]

It's missing the Android SDK (installation issue). You did try and reinstall the SDK or probably through Android studio, so you are on the right track. But it isn't seeing the folders it expects at the path in the preferences pane. You are on the right track.

You can also manually run the command shown in the debug message via command line to see what ADB and Android are saying.

[buoyant jolt]

For what it is worth, on 2021 and earlier, we found that openxr & the xrtk, you couldn't reposition controllers because of how it does the line renderers and raycasts out of the box.

To complicate matters the Quest controllers are 30 degrees off. And OpenXR (or at least the one it uses) can't give you the headset name or controller name. Making it impossible to show the right controllers and manage controller offsets.

I know that the offsets are fixed and finally adjustable in 2022 and the latest XRTK. But there are still some big issues to look out for in 2022. We finally have something stable but had to strip out some features- as it seems there are some known unresolved issues with the graphics pipeline that are breaking some common method used by all the day/night assets in the store fronts for mobile devices. I did some ugly hacks to get one working. But they (each asset owner) keep pointing at some specific known unresolved issue.

At any rate, 2020 was very stable. 2021 lts was stable. And we finally cleared a 2022 build as stable with issues.

I do not recommend 2022 if you support Pico headsets though or want to use third party weather systems or complex skybox systems on mobile headsets. And 2021 maybe still has the offset issues (ill check later). But I haven't seen it a meter off, just incorrect rotations myself.

[old bronze]

I spent over 7 hours trying to fix, and just few minutes ago I managed to do it, as you said by pasting the ADB command, seeing that it returns that such file already exists, so I run a command to delete it. Now I’m finally good, still thx a lot tho hahah

I probably fixed it the same minute you started typing the help message 😭 still really appreciate it

[buoyant jolt]

No problem! Android builds are fun 😄

[narrow briar]

Dude, I can't use XRTK. code is crazy. my 🧠 can't handle this many indirections

Offset issue was either IS or OpenXR being forever alpha. it's solved now. like when i dropped Mac and Linux support because they complain too much, i don't see myself supporting Pico unless sales > 10%, then i'd #ifdef offset

IS lag seems better in 1.5 with the USE_OPTIMIZED_CONTROLS flag

[narrow briar]

thanks for the heads up, much appreciated as i know it takes a lot of time to validate Unity versions 😅

[safe sigil]

Do you guys put Apple Vision Pro stuff here, or somewhere else?

[narrow briar]

I'll stick with 2020 and will backport my voxel stuff. I sure miss the new Job Mesh API but I value dependability more.

[buoyant jolt]

Yeah the Pico issue is a firmware one. You need to use firmware 5.0 by design from Pico, or it will crash regardless of the sdk/openxr for Unity 2022 and later.

But they only released firmware 4.8 to North America.

So no matter what you do, if you use 2022 and North America Pico- they will just get an instant launch crash.

It's a known issue, by design, with the Pico team.

Anyway I digress, just saying it's best to hold back on 2022 if you do cross platform client stuff

[slate delta]

does anybody know how to make it so an interactable object doesnt snap to my hand when i hold it? i want to hold it where i grab it, not have it snap to the middle of my controller.

[supple roost]

I love how I show off one little code doodle I've been working on for a few days and I get tagged as a knowledgeable person or something 😆

[pine bison]

I usually see it in #🤯┃augmented-reality rather than here

[uneven stirrup]

Does anyone here have any experience with hand motion smoothing. I am currently trying to implement it using the One Euro Filter, but it doesn't work. If I attach the smoothing script to my controllers, that have the XR Input stuff, it simply doesn't work. If I attach the script to my physics hands, that the rig uses, it works, but as soon as I start moving, they fall behind because they're in world space. Any ideas on how I could prevent this?

[gritty heart]

You can use dynamic attach. It’s a checkbox on the grab interactable

[slate delta]

ok thanks.

[gritty heart]

Are you using hand tracking? If so the hand package had a post process feature that we use to implement the one euro filter already.

Xri 3.0 lets you control the transforms in the rig directly. It’s totally possible to add smoothing scripts there. We add stabilization to ray interaction already though.

[uneven stirrup]

I'm using regular controllers

[gritty heart]

What are you trying to accomplish with smoothing? XRI should take care of that in a good way for you out of the box.

[uneven stirrup]

Well I don't use XRI

[gritty heart]

Ok well you can use a tracked pose driver with the pose, and then have a second game object that holds a reference to the transform of the first, and uses that reference to compute the smoothing

[slender echo]

In Unity, it seems to not add the references when I add XRI default input actions to my Input Action Manager, what could I do?

[proven radish]

I am using XR grab interactions and me and my friend are wondering how we can make the secondary button do the same function as activate, In simpler words instead of on interactable events using Activate to do a function (the trigger button on quest controller for XR) I am wondering how to re assign activate to be activated by a different XR call (for example the Secondary Button or "B" Button on the XR controller

basically I am trying to make a object you grab and when you press the secondary button on your controller it can do a selected function to the selected gameobject

[proven radish]

keep under 100k around 10-30k is lag free

31-100k will need occolusion culling

[gritty heart]

You should be able to add fallback bindings to the activate input action. You can edit the default input action map that comes with the starter assets to do this.

[buoyant jolt]

https://developer.oculus.com/documentation/native/pc/dg-performance-guidelines/

This second link has clearer batch and vert targets, which is what I use when benchmarking the teams effort

https://developer.oculus.com/documentation/unity/unity-perf/

[proven radish]

So what my question is, is it calling the trigger function in the script or is it calling something from a preset? I found where I can be able to change some of the inputs, this helps a lot but there is no way to have another Activate function with a different Input.

[white flicker]

ty!

[gritty heart]

Oh yes we only have 1 activate. I thought you only wanted multiple buttons for a single activate.

You might be better served with a custom component alongside an interactable that listens for select entered, then enabled input actions as you see fit, and disables them on select exit.

[proven radish]

How can I do that? I see to the fact that I only have about 2,000 hours and it is nowhere near close for me to figure any of this out 😂😭

[gritty heart]

• write a script that holds a reference to your interactable and to the different input actions you want
• in your on enable code, bind to the select entered and exited events on the interactable with simple callbacks in your script.
• bind to the is performed action on your input bindings
• on select entered enable the input actions, diable on select exited

With this you’ll get the is performed calls only when the object is selected and then you can do what you want

[proven radish]

Could I pay you to do so? I just don’t have the time to do it

[gritty heart]

Sorry I can’t take money like this. I work for Unity.

[proven radish]

Well thanks for your time man! I’ll try my best to use the advice I gave me

[gritty heart]

Good luck!

[tulip geode]

Hello guys, I started using XR Toolkit 3.0.1 and I have a problem that when I create an XR Rig instance and then change the scene, the lasers of both controllers are stuck at some point. This is probably related to NearFarInteractor.cs. Has anyone had a similar problem and know how to fix it? Restarting objects and components does not help :/

[tropic garden]

I'm having the folliwing problem in VR with HDRP

I have a DrawRenderersCustomPass that draws a World Space Canvas on top of everything else. The Canvas has a UI mask on it. I'm having an issue with it though. When looking through the Canvas, the world that is rendered behind the Canvas is lagging behind when the camera moves or rotates. It is almost as it is rendering the previous frame. Here are my custom pass settings:

This only seems to be a problem in VR for some reason

Anyone know what could be causing this?

[gritty heart]

I recommend grabbing the prefabs from the starter assets sample. Don’t configure them yourself

[slender echo]

When I press play on playmode in my game, my Main Camera's position moves to 0, 0, 0 and won't move when I try to move it. How can I fix this?

[tulip geode]

That same problem after changed scene

[gritty heart]

Your interaction manager and event system may be getting destroyed and it’s causing issues. You may have to mark them as don’t destroy on load

[slender echo]

Now it just goes down.

[tulip geode]

I make one game object which is spawned when the client is connected to the server. It is NetworkObject which has an inside XR rig, event system and interaction manager

[gritty heart]

That might be your issue. If any interactable is still in the scene it’ll create a new one and you might get issues as a result.

I recommend not destroying the manager and event system. The ideal is to put them in an additive scene that doesn’t get unloaded.

Load that first and then load your main content

Hi everyone,
I have questions about XRI 3.0.1, I would like to be able to teleport with a certain position of my hand (I have already done the pose and when it is detected it setsActive(true) my Teleport Interactor) so I have the pose of detecting except that I would like to validate my teleportation when my hand closes these fingers (like the Valem video)
Anyone have any information?

[tulip geode]

Yes probably it's that works, thanks for explain me. Btw. for multiplayer I should have one UnityEvent and one InteractionManager per player or it's should be one for world?

[gritty heart]

One per world

Well locally you need one in each player scene

[tulip geode]

Thanks for helping 🙂

[gritty heart]

No worries

[slender echo]

I get a CS0122 error from the XR Interaction Toolkit package. Here's a picture:
What could I have done to get close to fix this? I also get a few others of the same errors.

[gritty heart]

Your starter assets might not match with your xri version. I recommend upgrading your samples.

[cursive needle]

what is this error

i tried downloading XR

[gritty heart]

What editor version are you using?

[cursive needle]

2023.2.1f1

[gritty heart]

Ah. So that version is not really supported. Is there a reason you can't use the 2022.3 LTS?

Unity 6 is still in beta, and you're using an end of life tech stream

[cursive needle]

because this happens

[gritty heart]

Weird. Can you try installing the latest 2022.3?

.8 is quite old

[cursive needle]

ok i will see

[cursive needle]

works now

this issue isnt vr but could the 2023.2.1f1 version be making me problems in the build working differently than the editor

Anyone know where the Edit > Project Settings > XR Plugin Manager has been moved to in Unity 2023? It's gone.

Thanks.

[gritty heart]

I recommend sticking to 2022.3 lts if you’re working on XR. Unity 6 has not yet been validated for all packages yet

[glacial epoch]

Guys i am using meta open xr feature with xrit. when i start with my normal VR scene, it works fine but when i transition to MR scene (which has ARfoundation setup) and come back to VR, the enitre scene is stuck to my head and moves with it. it's as if no inputs are being detected.
The same happens if i start with an MR scene and go to VR in the same app session.

I have tried and checked all rig components including input managers, project settings, etc. The same works without any problem in other projects if i am using all vr or mr scenes.

I guess there is some issue with AR session/inputs/scene transition.
Any help would be appreciated.

My XR Origin won't move when I move, how

[gritty heart]

Have you tried the Mixed reality template? It includes a demo for transitioning to and from mr

[pallid sundial]

I have a question, can a socket interactor able to show hover mesh if the XR grab interactable object doesnt have a mesh renderer?

[gritty heart]

No I dont think so. Youre welcome to implementing your own socket interactor to do that.

[gritty heart]

So this is actually a bug that we’re going to fix asap with the XR plugin manager that doesn’t guard the Vision Pro build target properly.

The bug doesn’t exist on Unity 6 beta or 2022.3

[olive escarp]

I wanted to ask for some advice on a VR build for a meditation experience. I wanted to replicate an environment similar to the video below and make it for the Meta Quest 2. What would be the best way to replicate the grass while still being efficient for the Meta Quest 2? Would it be a stylized shader graph or something else? I tried using a prefab painter to paint some grass prefabs from an asset pack but they significantly hindered performance and dropped framerate

https://www.youtube.com/watch?v=HQW-nQU4PtE

[narrow briar]

do you use any third party bloom for quest 2?

[narrow briar]

a mix of DrawMeshInstanceIndirect and compute shader is the fastest you can get

[buoyant jolt]

Probably best to search it up on YouTube. There are a ton of videos on grass rendering performance tips and tricks

This one is a bit cringy but a good take on a process for it.
https://youtu.be/Y0Ko0kvwfgA?si=9Hgwu9RlniSsTNyV

[narrow briar]

is vulkan fast on q2/2020.3? i keep reading that GLES3 is faster

[buoyant jolt]

We found in 2019 -> 2021, there were a lot of Vulcan bugs that would cause problems for the Quest. It also seems to be what was giving URP some pretty unfavourable performance results for a while. I finally re-enabled it in our 2022 framework

[narrow briar]

thanks, did you find 2022 to be superior to 2020?

i think vulkan 2020 doesn't support tesselation, object just won't show up and i'm tracking the source

for those who got application space warp working, what are the benefits and drawbacks?

I've been chasing this one for a while. I was wondering why Oculus v OpenXR had offset controller...

super hacky, is that uniform in recent versions of XR? I'd rather not noodle with offsets like it's 1969 😄

[supple roost]

Holy shit, you're a genius

[buoyant jolt]

2022 definitely has its issues. There seems to be some core GPU bugs that have gone unresolved for a long time, and the latest shader graph breaks on older shader graph shaders, etc. Pico doesn't work as it requires a firmware update that isn't available in NA, lots of quirks. But I was pretty happy with how it was working out. The new compositor layers (experimental) break things (I.e video playing) if you add those, and can't be used for much that is useful (I.e. compositor between scene loading, which is the reason most of us would want to use it). Lots of shaders, like the OpenHands shaders, don't work in VR forward rendering for built in. But after rewriting a good 40 shaders I'm pretty happy and we could start using 2022 for production clients (minus pico) now if we want.

I got everything working quite reasonably well with 2022. But it was a lot of work.

Last item for me for our framework update is to figure out a solution to detecting the headset (as openxr likes to just list the headset as a OpenXR compatible device). Which i need to show the proper controllers.

That's been a problem for a long time, but not sure if it was ever improved in 2022. I'll hopefully know today:)

[glacial epoch]

Have you tried the Mixed reality

I have a question, can a socket

[narrow briar]

i'm not surprised. scene/asset loading in unity is very bad. could not play video without stutter for example. async is one stream only or you lose old streams silently

[narrow briar]

I switched my BIRP project to URP and gained realtime shadow + bloom so that was good. but is pixelated so i think it does a resdown by default. never seen that on Switch unless adaptive resolution is set in c# so im not sure what's going on

but still plagued by 1m offset in controller if switched to Oculus so i'm stuck in OpenXR which means no application space warp for this project 😑

[narrow briar]

or will just dig into the xrtk code because i really want to push this thing to do crazy visuals

@gritty heart which part of xrtk3 code base handles offset compensation?

[gritty heart]

Open up the near far interactor on the rig. See the interaction attach controller

Everything is built with interfaces so you can replace the attach controller or the curve visuals

Oh the offset you mean for the controller itself

There’s no code that does that

The controller model prefab just has an offset on it

You can move the transforms used by the interactors. Xri just uses transforms moved by tracked pose drivers

[narrow briar]

no i mean in the code. i don't want to add xrtk to my project because its too opaque so i need to do that offset thing in my own code

[narrow briar]

i'm talking about vertical offset, rotation offset is done in prefab at 88 degrees

[gritty heart]

There’s no offset code

The interaction code just reads whatever transform you give it

[narrow briar]

let's step back. i get a 1m coordinate offset in build vs desktop using the oculus plugin (openxr is fine) - when reading directly from the input system. that offset doesn't exist when i used unity xrtk so there is something in xrtk compensating for the wrong numbers that input system gives

[gritty heart]

Ah you know what it might be - the input actions doing fallback

Check the default action map

There are multiple poses that can represent the same transform, depending on what’s available

[narrow briar]

that?

[gritty heart]

yeah

[narrow briar]

never used fallback. 2020/IS 1.8.1 doesn't have fallback so I added the extra bindings as is... building the test to see if this works 🥁

I tried application space warp yesterday, is that expected that some materials don't show up?

i mean maybe special flags need to be added to output motion vector?

[gritty heart]

Check your urp shader stripping settings

Meta also has its own shader stripping built in the meta sdk

[narrow briar]

oh ok, never dug into that, where is it?

[gritty heart]

The root graphics option also has settings

Application space warp is a custom urp implementation though

[narrow briar]

yes i had to pull that off github

is it also a github special in newer version of unity? i saw an option in the stock VR template

(have to say, unity has one thing going for it over unreal: super fast build time)

[gritty heart]

Nah they dont maintain custom unity versions, but they may require a specific version that they test against

[narrow briar]

practically? need to pull a custom version of URP off their github or not

[gritty heart]

URP yes, editor no

If you want specific support on Meta's tech though, their forums would provide better support. I can help with Unity's tools and OpenXR.

[narrow briar]

why was the fallback node added to the input system? seems that fallback is the default behavior when you add multiple binding

[gritty heart]

So it solved your issue? This is the way that it was easiest to add given how xr input is built

[glacial epoch]

Anyone using ver 3 of xrit? I am facing some tracking loss issues when transitioning bw MR and VR scenes.

[narrow briar]

No it didn't, I added these and offset is the same but now the controller disappears unless i raise my hand to the ceiling 😆

[gritty heart]

It could be your AR session. When it gets destroyed it causes issues. Try keeping it alive in a base scene

[glacial epoch]

oh. i thought destroying it was the trick.

[narrow briar]

"given xr input is built" - can you explain more what you mean?

[gritty heart]

Well we support different interaction profiles that expose poses that are not always available. There are different modalities (hands vs controllers), and different backends (oculus xr vs openxr). Having fallback poses with processors that can apply offsets is the way to go for easy of use.

[plucky kestrel]

Hey friends. I was wondering if there was a good VR gizmo and debugging solution available. it's getting real tiring peeking into the nosehole for information.

[buoyant jolt]

I'm not sure what you mean, but if you need, you can create gizmos or use the simulator in a bind. Most of the work I do, I don't need to test with the headset. But I definitely do and want to when its time to check the interactions

[narrow briar]

@gritty heart stutter on link is back in latest 2022, logged as IN-74270

[gritty heart]

You said you’re using studio drivers though right? You might have to check if meta properly supports that.

[narrow briar]

1. studio driver means game driver that was thoroughly tested
2. how would you explain that 2022 is the only release that's stuttering, of any engine i use

[slender echo]

When I'm using XR Interaction Toolkit, it shows Missing Input Action Reference in my controllers in the XR Origin. What do I do?

[supple roost]

Crap... I'm late.

Watching this video now... it came out almost 7 years ago

I remember being 13 and absoluely fascinated by boneworks, this guy was making the cutting edge of VR technology when I was 11 years old

I'm only now reconstructing the very basics of what this dude made, over half a decade later

[gritty heart]

Have you tried using a pc that uses game ready drivers?

[gritty heart]

Have you tried clearing your library folder and freshly importing the toolkit and its samples?

[narrow briar]

yep, it's what this one used to have

again, this is clearly a problem with 2022 so i don't understand why you keep kicking the buck back to drivers

[gritty heart]

I recommend trying the game ready drivers to see if you can repro the issue then.

[gritty heart]

Because QA reviewed your issue and could not reproduce it.

The other thing I recommend trying is turning off hardware accelerated gpu scheduling (hags) in the advanced driver settings. I’ve personally observed some stutter with metas openxr runtime when it’s enabled.

[slender echo]

I haven't tried for the library, but for the importing of the toolkit yes.

[gritty heart]

The problem is probably with the samples. Make sure you do a clean install of those and do a reimport all in your project.

[slender echo]

How would I do that?

[gritty heart]

• delete your samples folder (or just the xri samples)
• close unity
• delete your library folder
• reopen
• import xri package samples (starter assets)

[slender echo]

Already done. It's fixed, thank you so much!

[supple roost]

What grass rendering asset do you guys use?

How would you make a GUI in VR? When I add TMP Text in my VR Canvas, it decides not to show on my end. What I mean by that is my canvas is linked to my camera and my XR Origin is setup with everything, but the text is just not visible.

I recommend downloading the vr template. It has many examples of ui

is there an API in OpenXR 1.8 to return guardian boundaries?
I see it's possible with OVRManager.boundary.GetGeometry but it seems deprecated after 2019

[slender echo]

Oh, thanks, will try @gritty heart

[narrow briar]

something that returns boundary even in quest link. seems not supported in the openxr backend

seems to not work in OpenXR backend. Is the solution to go full on Oculus backend? https://forum.unity.com/threads/quest-2-openxr-boundary-points-dont-change-on-recenter.1538962/

[buoyant jolt]

Also, would space UI. Generally you don't want to try and stick it onto the camera

Like a bad sticky note you can't focus on that won't go away.

[slender echo]

I set the thing to world space, and it's set to be connected to the camera, I'll try to link an image

Is it not supposed to be connected to the Main Camera? I'm new to developing with Unity, sorry about that

[buoyant jolt]

No worries, the problem isn't the connection, it's the scale and space

Try setting it to a world space of 0,0,0. And reducing the scale down to about 0.001, 0.001, 0.001

And a width of something like 800x400

[slender echo]

Alright, one sec

Where is the world space option?

Hi! I 've created a curved UI canvas for my app, and it works great, except that dropdown options and some small buttons are very hard to click. Interaction is set up with PointableCanvasModule and OVRInteraction (mainly ray interactions, except for keyboards).

When I hover over a button and press the trigger, it highlights the button and, once I release, activates the button - as intended. But, for dropdowns and small buttons, once I press trigger, it does highlight, but - if I move the controller even a tiny bit - it deselects. So, I have to keep the controller real steady if I want to interact with the dropdown or button.

Any button I manually create is fine, but buttons from pre-made UI like dropdown options and the aforementioned small buttons from an asset are affected.

[north path]

Just the position if it is not a child

[slender echo]

Alright

[slender echo]

There's a problem. My text isn't showing up under the camera when I go to the Game tab. What would I do there?

[north path]

Is the canvas in the view?

[slender echo]

What do you mean?

I can say the HUD is the same position as the camera.

[lone otter]

when i click on "oculus" in XR Plug-in Management nothing happens. Any way to fix this?

[north path]

Then it is not visible, as it's not in the camera view. It has to be in front of the camera

[north path]

Anything in the console?
Can you install it via package manager?

[storm ether]

If I disable the OpenXR plugin, nothing gets rendered in the headset; everything is pink or missing; keeping both active seems to work seamlessly. What gives? What's the way to fix this step?

If it builds and runs I ignore that screen because I can’t trust it

[spice yarrow]

yo, im attempting to use this coin asset for my vrchat avatar and this green bit seems to be invisible to me, anyone what it is and how i could see it?

for extra context: it's an animated coin, so it would trade places with the palms and shift in the hand.

[narrow briar]

I just discovered that frame stutter was caused by Phase Sync. Phase Sync assumes that your frame will be ready to be transferred to the display at a dependable tick and that's how it can gain 0.5ms over normal latency (transfer and flicking the LCD I assume). But if your frame is late, it'll still transfer the old one and for some reason also Oculus frame warping. So you end up with the same frame at the same head pose twice instead.

[quiet jetty]

I found a similar issue in the forums: https://forum.unity.com/threads/solved-vr-and-list-of-buttons-on-go-quest-difficult-to-click.768665/
But that solution uses OVRInputModule.

[quiet jetty]

I fixed it! The dragThreshold in the EventSystem has to be cranked up to 100.

[north path]

Oh interesting, didn't expect that. Thanks for letting me know!

[gritty heart]

Interesting thanks for tracking this down. I’ll pass it along.

hi everyone, someone had some issue with decal feature in URP when used with VR?
Decal projector works fine in play mode via Meta Quest Link but in build the decal have a strange effect (video)
Someone know how to fix?

[gritty heart]

Can you file a bug for this?

[shell kayak]

This looks like z fighting. Quest on Android uses lower precision depth buffers, so that could explain why it's only happening on device. No idea if it can be fixed though.

[narrow briar]

not the quest link frame stutter, in build. U6 no longer has that option

[gritty heart]

Right, I saw you said it was in build. Still good thing to flag

@gritty heart is there a way to get the guardian in Oculus XR?

[gritty heart]

idk. I dont work with oculus xr. Only Openxr, and I dont think theres an extension for that

[narrow briar]

oh i see. can you ask the person who does?

[gritty heart]

Thats a question for meta's forum honestly

[narrow briar]

boundary is needed to better integrate with the real world

you mean meta forum for unity?

how do you access room geometry in AR application?

"unsupported"

and box need special setup. no way we'll subject players to that. i thought there was a workaround to get guardian

new Oculus apps can't make calls to the native Oculus API? but unity OpenXR no longer returns guardian so.... solution? https://developer.oculus.com/documentation/native/android/mobile-ffr/

[wary wraith]

dose any one know too make it so a part of the model is invisble too the owner but not other players im using photon for context

[gritty heart]

Definitely post that on meta's forum

[narrow briar]

FFR same or does your team do that?

[gritty heart]

Unity works to expose features that Meta exposes via openxr. If Meta deprecates something, its not something we necessarily have visibility into

There are roadmaps to improve Unity's support of Meta's vendor specific openxr extensions, but if youre running into issues with the Oculus XR plugin, that's really an issue with meta's tools that we don't really have that much control over.

[narrow briar]

do you have a sort of spreadsheet of what you guys handle and what's meta's domain?

for example FFR might be openXR, not sure

this way i don't keep bugging you for meta stuff

and only bug you for openxr stuff 😉

[gritty heart]

Not exactly, but generally, I'd recommend looking at the OpenXR website and seeing if there's a cross vendor extension for a feature. If there is, then it's on us to make sure it's well supported.

If the extension has the word META or FB, then it means only meta supports it. The Meta OpenXR Feature package is where we're trying to bring features only meta supports to unity in a sort of cross platform way - through AR Foundation or xr loader plugins and such.

It turns out that there's very little that's a cross vendor extension

The consortium moves very slowly

[narrow briar]

Thanks! I'll do that.

it's interesting this mix of open and closed, i've only done consoles and iOS which have centralized information, so it's a bit of a egg hunt

[gritty heart]

Definitely

The complexity matrix is staggering

Generally meta is quite good at publishing their extensions, but theyre pretty much just function headers, so you dont know exactly how they work, and some of it requires specific handling in your vulkan renderer, or some boot config to enable - its complicated.

[tepid oasis]

Hi, I'm using the Complete XR Origin set up, and in the tutorial it has the rays that are supposed to allow for button clicking.

For some reason, in my game, the beams are much shorter and not highlighting the buttons I placed. Is this a part of the package I'm missing? I've tried redownloading it and it's done nothing :/

[gritty heart]

Do you have a tracked device graphics raycaster on your canvas? You need to be using that and not the normal graphics raycaster. See how the canvas is setup in the starter assets demo scene.

[tepid oasis]

I do, and I'm going to try just saving most of the canvas involved in the tutorial and rewriting it to see if that will save me some time. Good point in rechecking the canvas in the starter demo though, thank you!

[narrow briar]

i'm glad you and your team make this easier.

Cheers! It’s not easy but doing what we can 🙂

[olive escarp]

Does anyone have any advice on reducing the time it takes to build and run a scene on the Meta Quest 2? I've tried to Build and Run but unfortunately it takes forever to build as is stuck on "importing assets" for about an hour even though there's not that many assets in the hierarchy. Is this because I still have a lot of assets in the project in general?

[gritty heart]

There are guides for this but

• check your shader stripping settings, and how many material variants you have
• enable incremental compiler
• disable “optimize mesh data” in your player settings if it’s enabled

[olive escarp]

I'll keep that in mind, thank you

[narrow briar]

adding to what pvncher, might be mesh optimization if it's on it'll take forever , also if some assets are maya files it takes much longer on certain versions of maya

Has anyone experienced the Object Reset Plane script in the XR Interaction Toolkit behaving differently in new releases? Switched to 2022.3.25f1 and it no longer behaves correctly. Objects respawn for maybe 1 frame at their original position and then move back to the dropped position, repeats every check duration

[gritty heart]

I’ll take a look. Thanks for flagging

[subtle onyx]

I was slightly off, it actually only resets once. Happy to include a video if it would be helpful. Not throwing any errors in the console.

Seeing similarly strange behaviour when I reset objects based on Y threshold; objects become ungrabbable, though this might be another issue

[gritty heart]

Sure a video can help

We did change it recently but it could have introduced other issues

[subtle onyx]

This is in the Sample scene with the default ObjectResetPlane setup. On XR Interaction Toolkit 2.5.2. Haven't updated the toolkit, just the editor

[gritty heart]

Ah if it’s on xri 2.5.2 it’s still the old code… I think maybe 3.0 will possibly fix your issue then

I think what’s happening is that velocity isn’t being set to zero properly

3.0 should fix your material troubles too

[subtle onyx]

Ok I can try that, it wasn't an issue in the previous editor version so would something have changed there to cause?

[gritty heart]

It’s definitely possible the editor had a change that broke our script

Well give it a look

You can play with the object reset plane script tho btw

It’s just a sample

[subtle onyx]

yeah I might have a different issue, altering object positions is making them ungrabbable

[gritty heart]

Have you tried xri 2.5.3?

delete library, retry

[tepid harness]

Which Libary? sorry I'm dumb

[north path]

He ment the library folder in your project folder. That can help with some issues.
In general Unity and Meta have had some projects. I suggest to use the latest unity version and oculus (or openxr) xr plugin
Then in the meta link software make sure your drivers are updated. I am personally on the latest test channel
And make sure your quest is updated as well to the latest firmware

This is mostly for oculus runtime, as I do not use SteamVR at the moment

Like this

[gritty heart]

Are you using openxr? If so, make sure that meta is your default openxr loader. If you use virtual desktop on the same computer it tends to override that value. Also try closing unity and reopening it.

[tepid harness]

Thx for reply but I use Airlink

[gritty heart]

Right but you should still ensure your default OpenXR loader is meta.

[tepid harness]

ohh alr

This?

Wait

That's a program silly me

i did even have openxr installed

Uh what the flip

[gritty heart]

No you don’t need that

It’s in your oculus app settings

On the pc

There should be a tab that asks you what your default runtime is

The OpenXR settings for the standalone build target in Unity also have an option for this

[tepid harness]

ohh

And then I won't have that error no more?

[gritty heart]

Well its a possible cause

I would also recommend just pulling down the VR template with unity and seeing if that works for you. Its available on the unity hub

Its possible your project is not properly configured, and the vr template can serve as a reference.

[tepid harness]

Yea probably

Hey hey,

it has been already some hours now and I am struggling to find a solution to an XR problem. I would like to limit the movement of the in-game Camera to a circle around a certain point. How I expect it to work, is whenever the player physically goes out of the circle, the in-game XR camera remains at the border of the circle. Then when you go in the opposite direction, you move again in the circle independent of the real world position.

Could anyone give a hint on how to solve this? How to restrict tracking? It would be much appreciated!

I am currently trying to run a test build for an environment made in Meta Quest 2, however it failed with a compiled list of 126 errors, a lot of them having to do with shader compiling and temp asset creation. Could these be because I marked a bunch of objects that depend on these shaders as static and then enabled static batching? Any help would be appreciated, thanks

Hello everyone!

I'm thrilled to have joined this vibrant community! I'm currently developing a virtual reality application, envisioned as a virtual studio space, designed to run natively on the Meta Quest. In this app, I'm looking to enable participants within the VR environment to view a live video stream broadcasted from my computer using the RTMP protocol.

Does anyone have experience integrating a video player that supports live streaming via RTMP into a Unity VR project for the Meta Quest? Specifically, I need to embed this player as a texture on a material for an object that simulates a TV screen. Any guidance, advice, or references to similar projects would be immensely appreciated!

Thank you all in advance for your help and support!

I'm doubting it now hah, it's FMETP, but we might be using that for device to device. I can't remember what we used for RTMP, we needed it for a live streaming app for twitch and liveedu but it was so many years back I'm doubtful now if we used something else

Hello everybody. New user here. I would like to request some help. I was given a unity project that works for the Magic Leap with OpenXR. This project I have to make work with the Quest Pro.

I have imported an XRI interaction ready prefab that works (the main triggers perform clicks). Now I need to bind the inputs which work on the Magic Leap controller to also work on the Quest Pro controllers, and I have no idea how. For example, I need the side triggers to show and hide a specific canvas menu, where should I look to define that - on the canvas prefab, or on the controller prefab?

PS. my unity knowledge is very limited so I might not the appropriate technical dictionary

Is there any place to download the XRI Default Input Actions file? No matter what I try it just doesn't download with the toolkit

is this something that's already happened to others in the past and has a documented fix?

Edit: seems to be there now after just reinstalling Unity

[gritty heart]

It can happen that stuff is missing after an upgrade. You’ll just have to do a reimport. If that doesn’t work deleting your package cache in the library folder helps.

I've got this really weird issue where I can run my game in the unity editor with no issues using Oculus quest link but if I build the game into an APK and sideload it onto the headset, running it on the headset plays the game as a video instead of it being an actual game? 😅 Like I can't walk around or interact with the game etc

[buoyant jolt]

You need to setup the android manifest file

Running from the editor works as a PC VR experience. On device runs as an android app. Good for basic testing but very different from installing and using it

https://developer.oculus.com/documentation/native/android/mobile-native-manifest/

Now to make it tricky, sometimes unity embeds a manifest and sometimes it doesn't. And it's always only partial. So you'll need a few attempts to get it right depending on your versions of everything

[loud sequoia]

Ooo I see, thank you very much I will investigate 🫡

For anyone that has experience with scene transitions, what would be the best way to go about making a scene transition that fades to white on a timer? I'm making a scene where after a soundtrack finished playing, I want the user to fade to white into a brand new scene. Should I use an OnTimedInterval script combined with the one in the video?

[buoyant jolt]

No worries, that's pretty standard in all the VR toolkits except for XRI :D. There are lots of samples to do this. But https://github.com/OSVR/Unity-VR-Samples/blob/master/Assets/VRSampleScenes/Scripts/Utils/VRCameraFade.cs
https://developer.picoxr.com/document/unity/screen-fade/
Etc

Osvr, Pico, Meta frameworks all have them. Just gotta grab one and use it.

The Pico one is what we use

[olive escarp]

Thanks a lot for sharing this. For the script from the GitHub page, do we attach that as a component to the XR Origin or the main camera child of the XR origin ?

[buoyant jolt]

Usually, you just attach a screenfader script to the camera. That can then be called to fade in and out. You'll usually have a SceneLoader script somewhere with an IEnumerator for scene loading, that loads a scene additively, waits to complete, fades, then triggers the load. And reverses it on a scene starting up. That'll give you the fade to white in and out at each scene transiton

[olive escarp]

I'll experiment around with it, thanks again

I'm trying to play a main camera animation in VR, but the animation doesn't seem to play. I think it's because the head movements override the camera's new position and rotation. is there a way to temporarily disable the input to the headset just while the animation plays?

[buoyant jolt]

If you don't mind making someone get sick, you can disable the tracked device component to stop the camera from overriding you
