I can't use airlink lmao

I actually cannot use it

[hidden moat]

Greetings; we have a sort of legacy project in 4.24 for mobile VR on Android (Quest 1). We've consistently had some lightmap issues on building to APK, which usually just required rebuilding lighting. A few months ago the dev team reported lighting issues and I was brought back on to look into it again, but when I saw what was happening now it seems that ALL textures packaging in the APK are extremely low resolution, blurry, and this affects the lightmaps as well obviously. I'm wondering if anyone out there has an inkling what kind of global setting might have universally affected all textures in the packaging of the project to Android ASTC?

If I change Mip levels for any given texture then it is no longer blurry when packaged which makes me suspect an issue with the VR camera and "screensize" setting for LODs and mips chosen. But I'm not certain where someone may have unintentionally globally changed this calculation for our VR camera.

If it helps, I'm generally the only person who works on the texture files individually, so something happened globally that affected all textures. So that's what I'm looking for - any advice on what may suddenly make all textures display at their lowest quality in android apk in a project that was previously building with higher resolution textures displayed.

[dusky talon]

Hello, I want to try in making a VR game for quest 2, but when I start a project I dont get any project settings, to set for android (only "starter content" button is showing up)

[hidden moat]

@dusky talon what engine version are you using?

[dusky talon]

4.27.1

[jovial hamlet]

I'd diff all config files with an older version to see if anything suspicious shows up
like sg.TextureQuality or TEXTUREGROUP properties, which can affect mip bias

[hidden moat]

@jovial hamlet good call; Ill try that

Thank you.

@dusky talon You're starting engine, going to Games and then VR for a new project? You'll want to follow a starting setup guide I'll link you here. There are unfortunately no one-click options to set up the editor for packaging to mobile VR.

But it's fortunately well-documented to set up 🙂

[bronze sable]

Hey, everytime i try to build to Oculus quest 2 i get this error saying that an item key has aleady been added

any idea how to solve it

?

[sturdy coral]

you might try on the virtual desktop discord and see if they know a fix

[reef willow]

Hello, I'm building a cross-platform game that uses OpenXR and Hololens, i was wondering what implementation of spatial audio would most likely work with all these platforms. It seems that resonance was used in fortnite.

[broken hearth]

Hey, I was thinking about starting a VR project in the near future and would love to hear some quick / general opinions on whether unreal is a good engine for the XR space currently. Is UE4 actually the best choice to get into XR development assuming that I already know my way around the engine and C++? And will UE5 bring significant changes for XR development or is the focus of the new feature set still mainly on regular 3D?

oh and is it possible to develop for say Quest2 on a Rift CV1 without issues, or are the builds different enough that I would need a new meta HMD to test properly / ensure stability

[jovial hamlet]

if you want to develop for quest standalone, it is not feasible at all without a headset
there are a lot of weird quirks
if you develop for PC (link/airlink), it's probably gonna be fine, but still nothing beats having your target hardware

[broken hearth]

good to know, ty !

[golden kestrel]

I use link, not virtual desktop

How do I implement VoIP for quest 2?

[polar valve]

You can either use the Oculus platform VoIP or Unreal VoIP. I had a lot of issues with the native Unreal VoIP on 4.26. This plugin seems to work well though https://www.unrealengine.com/marketplace/en-US/product/cross-platform-voice-chat-pro

[past forge]

does anyone have an idea how to make blob shadows without mobile hdr?

[stiff fern]

Hi! Oculus question > Does somebody knows, if it's possible to distribution switch from app-lab to store, and (vice versa) once the app is created?

[polar valve]

Afaik it isn't possible to do it properly without scene depth

[trail shale]

is VR still borked in 4.27?

[median wasp]

For what device? Its working perfectly fine for Quest 2 given you have the correct configs.

[trail shale]

Index

[royal plume]

Started up a new project and for some reason the sky is black in the quest 2, any idea why?

Any help is greatly appreciated :)

[tired tree]

@trail shale borked how? index has never had issues in 4.27 afaik

[manic tapir]

I really do appreciate it. I'll use the plugin. :)

[trail shale]

just talked to a dev who said don't update to 4.27, it totally breaks VR - I came here to confirm it

[tired tree]

Not sure who that dev is, but they are pretty wrong?

they might be confused about openXR being default on the engines template now?

[trail shale]

incidentally - does openXR reach across windows into the input stack - would there be a way to maintain input handling even if the window is switched? (I'd pay a dev to do this but I don't know what to type of engineer I'm looking for)

[tired tree]

it does not change input handling in that way no

[trail shale]

didn't think it would but I figured I would check

[royal plume]

Solved: Mobile HDR wasn't playing nicely with the sky sphere

[bronze sable]

I'm trying to build to Oculus quest 2 but i get this Error, I also use GAS plugin. but not sure what the problem is

it just runs for 1 sec and just closes on the quest

[chilly ocean]

I’m using 4.27.2 with valve index and it works fine

[ivory juniper]

Anyone run into the issue where lighting is way off for an android/VR build but building an exe and preview in editor is totally fine? We get was appears to be heavy shadowing/characters normals look off in some spots/glossy floors when building to Android, but its also not 100% consistently an issue either.

[trail shale]

thank you for confirming this

[proper anvil]

I guess it has been asked a few times, if so pls forgive me.
I'd like to only render in HMD, and disable the rendering on the monitor, for performance reasons.
I tried the command for disabling stereo rendering, but that disables the HMD.
Tried a few from here, but most of them didn't do anything or just did the thing above.
https://nerivec.github.io/old-ue4-wiki/pages/vr-console-commands.html

[somber cloud]

I am using 4.27.2 with Quest 2 and it works perfectly fine. (Except when I personally break something of course...)

[past forge]

Thank you for your replie, will use mobile hdr then.

[rocky nexus]

If only it worked on quest

[somber cloud]

Quest and low price points are why we can't have pretty games/shaders!

**Person when VR headset priced above $300: ** It is so expensive who would have that kind of money to waste on technology that replaces so quick.

**Same person:**Can't wait to spend $1200 on a new phone that does nothing new compared to my current phone I got last month.

[tired tree]

pretty disingenuous when the more expensive headsets generally require a capable computer as well currently.

[somber cloud]

You misunderstood, I am not talking about currently available or developed headsets.

If the public accepted a price point of $999 for a wireless device it could be built. Clearly the influx of players on the Quest 2 price point will drive the market down to that level for awhile though.

A gaming computer could be purchased if you skipped a generation or two of phones. So my "disingenuous point" still stands. No excuse to not have a proper computer if you have a modern smart phone.

[tired tree]

Plenty of excuses......most people use their phones as their computers.

Also you are still form factor limited on headsets, there is only so much you can pack into a stand alone currently.

price point aside

[somber cloud]

Very true

Heat always causing problems everywhere in the world!

[tribal osprey]

There's a lot of subtext and shady marketing practices that drive the smartphone craze though, it's not quite the same

Companies offer free upgrades with existing plans which gets new phones out to markets and drives hype for more people to go out and pay full price for a new phone to keep up

Also It's essentially like a designer luxury now, having the new phone is a point of superiority and class

VR Headsets aren't mainstream enough for that yet

Although it's almost undoubted that they will be at some point

[south fractal]

Question - The install for AR development instructs the user to install "Android Studio 4.0" from May 2020. But the latest version is, "Android Studio 4.2.2" from June 2021. Why should I use this much older version instead?

[rocky nexus]

presumably the idea is that it was tested to be working with engine version you are using

you may find that it was whishfulf thinking

[south fractal]

Ok thanks

Which version is for 4.27?

Or is 4.27 not supported yet?

[south fractal]

That image comes from the bottom of this page...
https://docs.unrealengine.com/4.26/en-US/SharingAndReleasing/Mobile/Android/Setup/AndroidStudio/

[rocky nexus]

latest works for me for 4.27

[proper anvil]

Just wondering if there is a way, to disable monitor rendering, and only render in the HMD?Mainly for performance reasons.
I tried these, but none did what I want:
https://nerivec.github.io/old-ue4-wiki/pages/vr-console-commands.html

[rocky nexus]

Unless you have extra spectator camera it just shows view from one eye, that should be essentially free

[sharp forum]

question about switching the view on the PC while the VR player is playing... how Can I manage this without changing the view in the HMD?
I tried using a sceneCapture2D and setting the 'SetSpectatorScreenMode' to Texture, but the screen capture makes the VR Player view choppy.
I tried 'SetViewTargetWithBlend' Setting the new camera to the 2nd ingame camera, but it also switches the HMD view to that camera.
Is there a way to allow the PC viewer to switch between cameras while the VR player plays?

[sharp forum]

If you only want to render to the HMD, then create a sceneCapture2D camera somewhere. Put a card in front of it with your game logo, or some image. Then capture once. Or you could just add a texture (material) to the camera (I haven't tried this).
then use the node 'SetSpectatorScreenMode' set to Texture.
Make sure Capture every frame is NOT set to ON (as it is in default).
This will make it so there is a single image on the PC, and it will not be showing the HMD view.

[proper anvil]

will try thanks

[sharp forum]

Also, (if you are not already using it) try Round-Robin in Project settings. It will alternate between rendering Left eye and right eye, so both eyes are not rendering every frame. saves a lot of fps.

[proper anvil]

I don't have gear to test it now, but will do on Monday. Cheerios

[tired tree]

@sharp forum huh? round robin "occlusion queries" won't alternate rendering, its for the occlusion.

it just samples occlusion in a cycle, not rendering itself

[sharp forum]

ahh... correct. sorry. It does save a lot of fps, though. Mine jumped from 80fps to 110, after that.

Yeah it checks what should be rendered, by alternating eyes, instead of checking everything for both eyes each frame. mistake.

[fervent raven]

guys any help !, z postion doesnt changes when a go down with the headset !

[sharp forum]

I had someting like this before.
Check what you are trying to get the information from.
If it's the actor, it may be looking at the pawn, and that is always on the ground. the HMD and the component it is attached to move independantly.

[hard relic]

Hi, any way to avoid translucent/adaptive material to rendered in front of everything in forward rendering?

[rare tulip]

When using the oculus openxr runtime, does the Get Motion Controller Data node Hand Key Positions and Hand Key Rotations currently if you're holding a controller? It works wonderfully for SteamVR's xr runtime and index controllers, so I'm wondering if this is expected behavior with Oculus via link. Testing with UE5 EA.
Edit: 5 EA and 4.27 oculus touch via link motion controller data do not contain key positions/rotations.

[radiant wind]

My main menu is super zoomed in when my game is launched in VR. Doesn't seem to be affected by the UI scaling settings. Not sure how to fix it. It makes it impossible to get into the game in VR without console access to load directly into the level.

[rocky nexus]

are you trying to use simple hud? you pretty much need world widgets for vr

[trail shale]

We are doing a demo at a conference for our training VR simulator - I've done it before but this is the first time I've had extra equipment - is there a reason why I wouldn't use 3 trackers, if I have space and can secure the tracker stands effectively?

[exotic mango]

Does anyone know within blueprints I assume how to change the texture resolution within the game sorta how you can go on sidequest and send the adb command but instead I just want my game to automatically do it for the player or atleast give them the option.

[radiant wind]

Okay. I'll look into it. At the moment they are regular UMG widgets

[rocky nexus]

in vr they are also regular umg, you just show the in world

[rare tulip]

Are the trackers steamvr 1.0 or 2.0? 1.0 will have a flat front, 2.0 will have a curved front. If 1.0, you can use a max of 2, if 2.0, go nuts.

[trail shale]

yeah they are 2.0

some might even be newer because I RMA'd one last year

[tribal lintel]

The 2.0 lighthouses/base stations can support up to 16 running at a time for huge playspaces, HTC has tested it. Unless your planning on physically walking further then a 9ft x 9ft playspace, I would stick with 2. More doesn't always mean better, It looks like it took some configuring to make the base stations not interfere with each other, so if it comes down to demoing a project I would personally just stick with 2, both around 7ft high, in opposite corners pointed to middle of playspace so you don't risk anything going wrong during the presentation

[trail shale]

Thank you very much - this is exactly why I asked, I wasn't sure if there was some possible interference that could occur

[tribal lintel]

Cheers, while you might get 0 interference out of the box, I wouldn't risk it without some testing

[trail shale]

Yeah, it wasn't the time to experiment but I can at least mention it is doable

[tribal lintel]

definitely doable, HTC shows you can get 33x33ft off of 4 base stations, and with 16 a total area playspace of 726.5ft lol

[trail shale]

Why is this popping up the moment i move the motion c ontroller -

it's never happened before, it's like I put a break somewhere (I didn't)

It only happens when I move the motion controller itself, not when I press a button - I leave it on the desk, it's fine

[sage gulch]

anyone pushing a SteamVR manifest file into steamworks? It doesn't seem to see mine, as best I can tell.. I used to use Steam all the time back in Q3F/TF2 days but have mostly been Oculus native the past few years.. looking for some SteamVR hardware testers for Bombyx Edge Alpha branch
https://store.steampowered.com/app/1814920/Bombyx/

when listing the path to the manifest file is there some formatting trick? Is there a preferred forum or chat for Steamworks/SteamVR integration?
Thanks

[celest basin]

I'm trying to get shadows working in VR in 4.27 and I need some advice about the changes that happen when you run something in VR as opposed to just running it in the editor

This what I got in the editor

But when I run it in VR, it's like it just turns all the nice shadows above off

basically looks like that

I'm running a quest 2 on an rtxgi 3070ti, I have forward rendering off and also disabled stereo instanced rendering

Is there a way to say to 4.27 please STOP DISABLING SHADOWS IN VR???

Just to be clear, outside the house, there is some very low detail shadowing on the outside walls from the eaves and roof so I don't think the shadows are completely disabled, they just seem to be turned down to crappy useless quality levels

[celest basin]

Aight, so it's raytracing yah, won't work in VR

Here's what's so annoying about that:

Two cameras, in the editor, rendering two different angles of a scene, fully raytraced at 60fps

Why why why can't we just send one camera to one display in the the headset, and the other to the other?

[wet canyon]

is there a way to do VR development without wearing the HMD

[mild trail]

I need some help, cant figure this out. I am getting this messege when trying to build for quest2.

LogPlayLevel: Error: ERROR: Stage Failed. Missing receipt 'C:\Users\kugle\OneDrive\Desktop\Quest2Setup\Binaries\Android\Quest2Setup.target'. Check that this target has been built.

The Binaries folder does not exist at all.
Can anyone help please?

[sonic lake]

@wet canyonmost dev use a traditional pawn/character and then revert to VR when needed. The alternative is to disable/block the proximity sensor of the HMD (with Oculus you can do it from the dev hub) so it works even if you are not wearing it.

@mild trailif the binary folder doesn't exist you may have other errors before. Or your dev environment is not set up properly.

[mild trail]

@sonic lake This is actually the only red I get in my log. Where do I go about looking for a solution.

[sonic lake]

@mild trailI would start by not building to OneDrive, that may cause issues as well

Also make sure your SDK/NDK and Android environment are setup properly, including the manifests for the Quest2.

The header of the Android settings inside the engine config should turn green.

[mild trail]

Header is green, now running from D: -> Getting a new error
LogPlayLevel: Error: ERROR: cmd.exe failed with args /c "D:\Unreal\VidenDjurs\Quest2Setup\Intermediate\Android\arm64\gradle\rungradle.bat" :app:assembleDebug

@mild trailI believe your dev environment is not setup properly

Did you follow a guide or something?

[mild trail]

This guide https://www.youtube.com/watch?v=TXQhGjVZJ-8&t=119shttps://www.youtube.com/watch?v=TXQhGjVZJ-8&t=119s

Pretty good tutorial all the way up til it failed 😉

[trail shale]

How do I get the touch events (like putting your finger just gently ON a button) from the index? is it somehow an axis event?

[sonic lake]

@mild trailI am not familiar with that tut. You may want to review all steps and make sure you haven't missed any. Also it is 6 months' old so some SW versions may have changed meanwhile.

[rocky nexus]

isnt that just another input event? button touch instead of clicked

[trail shale]

yes thank you - it wasn't coming up but my dumbass wasn't looking in the right spot - found it

I cannot develop when this occurs though

\

[mild trail]

@sonic lake I've reviewed all steps and been through a bunch of websites looking for solutions all day long.

@sonic lake Do you have a suggested tutorial?

[rocky nexus]

You check if its valid, it isnt so it triggers

[trail shale]

why is it checking it? it only triggers when the motion controller MOVES

it's not happening otherwise

[rocky nexus]

Dunno, log some stuff

Perhaps you bound wrong method somewhere

[trail shale]

all I did is debug from VS, to check some other crashes

[sonic lake]

@mild trailnot really, beside double checking against the Oculus Dev documentation

Maybe someone else on this channel can recommend an alternative tutorial which worked for them

[tired tree]

@trail shale look in your key bindings, there was an index key that got changed in 4.27 that will throw that over and over until you un-map it

any vr keys in the bindings that show a keyboard icon are not loaded as VR keys

[trail shale]

I'

I'm on 4.26

[tired tree]

w/e

same thing

input changed in 4.26

don't remember off the top of my head which key was re-named

but you just have to remove and replace

[trail shale]

so I'm looking for vr key that is listed under keyboard?

[tired tree]

in your mappings that has a keyboard icon

[trail shale]

something like that, I'm looking for??

It's weird - the crash happens when I move the controller, but as you said, maybe I'm thinking it's when I move it, when it is really a "touched the grip" event

[trail shale]

otherwise I have no idea why it crashes when I simply lift the motion controller off the desk

Does this seem familiar?

And would these cause crashes in a build? Or just editor?

[tired tree]

@trail shale yeah it was that button

and it will throw that as a crash only in debug enabled builds, its a check

don't think it would crash out in shipping

[trail shale]

Dude, I am still indie dev, no budget, but is there a way I could buy you a beer? I would have had no clue and there is hardly anything I could find on google explaining this - god knows how long I would have searched for that

[tired tree]

nah, paying it forward, had it show up when I was porting to 4.26

there is no documentation around the change so had to find the cause myself

[trail shale]

ugh, it's like all the companies doing VR (Valve, Facebook) WANT it to not spread

I know the default bindings save when I change something - but how do I KNOW the changes have taken affect? I regenerate action/axis manifest ,(that whole 1.2.3 thing in the steam vr menu in the unreal editor menu)

[tired tree]

it should have taken effect, but I guess just see if it crashes now, it shouldn't

[trail shale]

it didn't - thank god

back to the issue of the touch event I made in the action menu not being detected, can't get a simple print string to fire when I rest a finger on the facebutton

[tired tree]

open the steam input overlay and check if its actually mapped

the auto mapping is fairly bad

if you turn on steamvr developer mode it lets you save over the default mappings for the program

[tired tree]

have to have the program running for it to default to it

[trail shale]

Hmm - is there a good resource to learn about this default mapping - I'm not clear when I need to do it and when I don't

for example, when I sent over a build to another dev, they didn't have to do anything there

[trail shale]

So what is the right syntax for just touching it? is it touch?

                   "mode": "button",
                   "path": "/user/hand/right/input/b",
                   "inputs":
                   {
                       "click":
                       {
                           "output": "/actions/main/in/360Jump"
                       }
                   }
               },```

[tired tree]

you can rebind right in the overlay if you want to avoid manually editing json

[trail shale]

it put it in there finally, when I changed it in the editor - but as integrated as perforce is, it doesn't tell you (at least not for me) that the knuckles.json is not checked out

so it phantom saves them

default bindings are checked out though

tried reloading action manifest and all that, can't get the event to fire

[trail shale]

What is the correct process for this? I see it listed in the defaultInput.ini - I've confirmed it is also in the Knuckles.Json - I've regened/actionmanifest all that, and I've restarted editor and Steam VR - I can't get that input event to show up in the overlay

[tired tree]

right button touch doesn't show up in your editing?

[trail shale]

the touch event

that I created

what is the defined process - I see 2 events I made there, from last year, but the process was so convoluted I just probably got lucky but never documented the "step 1, step 2, etc)

scratch that - the event IS there, but is this setup correctly?

[tired tree]

that that should fire

though not sure why you have multiple mappings there

[trail shale]

Because I have no idea what I'm doing

[tired tree]

you have radio key up, 360 jump and another mapping just for the touch

make them all one mapping

and you can't use the same button for two seperate actions, it bugs out the input system

[trail shale]

ah

[tired tree]

can throw random input events

delete two of the entries and add the righ bbuttontocuh to the touch entry on that

[trail shale]

after you edit the overlay, you need to do what/ it saved

[tired tree]

override developer defaults

if you don't do that, you'll have to manually port changes back by copying the json files to your project or pasting the text

if you are in developer mode it should let you override defaults though and it does that for you

then you need to lock down the json files in version control

[trail shale]

where am I looking for what override

[tired tree]

and not auto generate them

[trail shale]

can't find the developer override

[tired tree]

bottom of the input overlay, if you don't see it you didn't turn on developer mode in steamvr

not sure its called the same thing anymore tbh, haven't had to go into that section of settings in a long time

but it will give you more debug options and this button:

[trail shale]

found it, it was at the top

Why is it you don't have to do this in a build though?

like once I get this working, package it, It will deploy fine and the keys will work

[tired tree]

you are setting up the input

that gets packaged with the game

it sends these jsons files

[trail shale]

save failed - I checked out the config/input folder

that was when I tried to "Replace default binding"

[sage gulch]

I've been stumbling over this for a while now and finally got to the screen

afaict you actually can map inputs to multiple actions, but you need to watch out for having them active at the same time.. there is also a 'consume input' box for the actions in bp

[trail shale]

Anyone here have a index controller asset with the keys set as different materials (or with a dynamic material instance for the keys then, if you just have one element)

[sullen vortex]

Jacob, i had the same issue, had to reinstall all Android SDK and fixed it

just make sure you remove all android related folders before installing the SDK again

[trail shale]

like did someone fix the damn backwards B on the motion controller yet?

[dreamy ivy]

After popular request. I created a video dedicated to my Oculus Quest 2 settings in Unreal 4.27 which I use daily to build projects. I also cover some reasons why your build might fail so it could be helpful for those having issues.

I also go over some settings you can use to get your project running better reducing some overhead by half and dropping the CPU level down to 2 so your quest isn't running as hard. As well as more settings to think about.

https://youtu.be/y3xFZF9Nyt4

[cerulean pasture]

Hey, I'm currently developing a product using a Quest 2. When I PIE VR the first time, everything works just fine. However, when I try to PIE again after the first run, the editor freezes up and I have to force exit and recompile. I was wondering if anyone has had this problem before, and what could be done to fix this? Thanks!

[velvet panther]

Hi, not sure im in the right channel now... But I am having trouble making my Oculus Quest 2 controllers work properly with UE4. I can walk around with no problems using the A button or the right stick. But no other input works. In the default vr map I cant pick things up or see no laser pointer. All guides I find is about setting UE up for running on Quest but I am looking to do a PC aplication that has to work with multiple headsets. Will these Android solution solve my problem too?

[sharp forum]

If you are running through PC, then are you running through Steam?
You can change the bindings.
Also, you might want to check the Project Settings> Input, and then check your Action and Axis controls, to see if any of those are set to Quest Inputs.

[sharp forum]

It crashes when you did something odd, normally.
For me, it was infinite loops. The game would pause then crash.
You should normally get a bunch of red text in to output window.
If it works the first time, but not the second, there is something sticking around.
did you create a save, that is getting called?

[velvet panther]

I have tried both with SteamVR and Oculus native. Have also packaged the project with the same result. In the input settings I have Oculus Touch bindings by default together with valve, MR and Vive. Maybe that is the problem? I can´t find any input specifically for the Quest though.

Hello All, i was getting some weird results on Quest 1 and Quest 2 while doing performance profiling. Quest 1 is giving better performance than Quest 2!. on the same application build and settings.

When i look at a trace in Android Monitor the surface resolution on Quest 1 shows up as 2432x1344 compared to 1440x1584 on Quest 2. Any directions on what could be causing this?

If I understand correctly Quest 1 does not have hardware multi-view vs quest 2 which has hardware multiview..

could this be causing this?

The binning phase seems more or less same on both devices however the rendering of tiles seems to be twice as expensive.

[trail shale]

how do you make it switch back to steam VR when you are streaming a level? it just kills the frame rate, I would rather cut out and just wait until everything is loaded

[jaunty wadi]

Hi all hope you are doing well, I have come across a weird issue when testing meta humans in a networking scenario if I place them on the Server level and I join in with a client sooner or later the app will crash on me and I have this in the debug log. I am using Oculus Quest 2 and Vulcan API. If i test the same map, but in standalone.. I am not experiencing crash. Any advice or recommendation would be much appreciated

[cerulean pasture]

I get no red text, we have multiple people working on the project and I'm the only one with this issue haha.

QUESTION:
Heyhey, i am packaging my vr game and when i spawn my head is always in the floor/ in the PlayerStart Origin. This does not happen in editor, it works fine there. Changing the VRPawn Set Tracking Origin to "Floor Level" or "Eye Level" has both the same result spawning with the head in the floor.
Does anyone know how to fix that?
Appreciate the help 🙂

[trail shale]

What happens if you reset orientation of the headset (like in Steam VR or Oculus)

[glad sedge]

Changing the first image to the second fixed it (Inside VRPawn blueprint). Not sure why, but its an easy fix and now i am spawning correctly when running the packaged version. Quite unfortunate that i have to change the premade VRPawn blueprint for it to work

[tired tree]

its because its taking awhile to spool up the tracking system

you would want to delay a bit before checking if the hmd is enabled

[trail shale]

Not sure why, but its an easy fix and now i am spawning correctly when running the packaged version. Quite unfortunate that i have to change the premade VRPawn blueprint for it to work

This is one of the reasons VR hasn't spread more - not enough support for developers - higher ups just don't care enough at the moment

[tribal lintel]

Yeah speaking of support for developers, how in the sam hill are people developing for quest 2? I can't keep the device wirelessly connected to ADB/ODH no matter what I do, not seeing others having the same issue when searching

[jovial hamlet]

You get used to the pain haha

[tribal lintel]

Oh wow please tell me your joking 😂

well good thing the $80 16ft usbc cable is $20 off today on amazon

[hollow tiger]

Can anyone recommend some packages or learnings to buy around blueprints to place items in a VR game using a catalogue similar to how you would in the Sims games?

Ty in advance

[lapis tide]

Hey, so I just found this vr channel haha. I got this problem when playing my game on the ocolus quest 2. Does someone know what causes this problem? I tried googling for an answer but couldn't find anything

[robust bramble]

what should i buy for vr development?

can anyone give advice?

[jovial hamlet]

Does anyone know how long does it take for Oculus crash analytics to update? Or do I need to somehow enable them separately?
I've experienced crashes on my Quest a day after the update went live (and most likely other users are affected too), but after several more hours the crash analytics still report 0 crash events.

[sharp forum]

I'd start with a Computer and a VR setup, like Valve Index or Quest 2 HMD. Then, get a development software like Unity or Unreal.
This should get you started. The rest is mostly study and practice.

[earnest root]

I have a Rift S and I'm thinking about upgrading to a quest 2. The main reason I'm considering is just the need to not have a long cord constantly coming from my back and over my shoulder as I move around. Development wise, do you guys feel the quest 2 is good? I heard each time you want to test a change you need to make a whole deployment for the device

[jovial hamlet]

If you develop for the PC, your workflow won't change, you'll still typically connect your Quest to the PC over wifi instead of a cable
You only need to deploy your game to Quest if you want to test a native Quest game

[earnest root]

Cool, thanks

[subtle raft]

anyone know of a product or way to track a gamepad controller with a Quest? There's OpenCV if it was possible to access the passthrough cameras and ARCore, is there a little tracker like Vive Tracker with IR?

[dry fjord]

does Reset Orientation and Position not work with oculus touch or over air link or something?

or does it not do what I expect? I see it nudge a tiny bit the first time it's called, but it's not calibrating for HMD orientation at all

[tired tree]

its bugged in openXR in 4.27, it got fixed but don't remember if it made it into the hotfixes or not

well...not sure bugged is the right word, they forgot to implement it for openXR

pretty sure the fix is slated 4.28 or ue5 since it required a decent amount of overhaul to the openXR codebase

[dry fjord]

heh

lemme see if I'm even using openXR

either oculusVR or openXR didn't work for me at all. it was one of them....

damnit I'm using it

guess I'll try rolling my own again

[tired tree]

its literally just a transform applied to the cameras location

they take the current and inverse it and apply that to all future updates

should be fairly simple to emulate that by moving the vr root

[dry fjord]

that's what I tried. relative transforms are always finicky though

[subtle raft]

Mixed Reality OpenXR is not workign right either

so sad

[distant nest]

One downside of doing wireless to Quest 2 is that with the headset unplugged, it goes into a deep sleep after a few minutes. So you lose your connection to the Oculus streaming process.

So if you are doing a bunch of headset on/off testing, you're often better off leaving it plugged in to avoid that. Otherwise it's headset on, re-connect oculus airstream. Sometimes that fails. Sometimes you have to then restart UE4. It can often be a big wrinkle in rapid prototyping.

[jade kettle]

Unfortunately I don't think there's a way to do that, that part is closed off

We've looked into accessing the Quest's tracking cameras/data and use it to find a tracker that would represent a zero transform for co-location/multiplayer VR

I couldn't find an opening for it

Though anyone is free to prove me wrong

[distant nest]

I've never seen such an interface either. But if you're just trying to calibrate some zero transform for same-space VR, you can do that with some photogrammetry (or good space measurements) and a cardboard box taped to the floor to use as a fixed point cradle for initializing the headset orientation.

[hallow knoll]

Which UE version, device and runtime are you using? I haven't come across that issue on PC or Oculus Mobile

[hallow knoll]

We're not going to know what the issue is from your screenshot alone. Provide some more details to help us help you 🙂

[glad sedge]

UE 4.27.1, Oculus quest 1 via Oculus link and steamVR, VRPreview (if that is what you mean, not sure)

[hallow knoll]

Is there a particular reason why you're using SteamVR instead of Oculus? (referred to as the Runtime(s)). While SteamVR's OpenXR runtime supports Oculus devices, support isn't 100% yet, and we rarely test that path

PSA: If you don't know which OpenXR runtime is set in your environment variables, get OpenXR explorer: https://github.com/maluoi/openxr-explorer. You can switch runtime in a dropdown when switching VR hardware (Oculus/SteamVR)

There's also options in both Oculus and the SteamVR software, but they only let you switch to their preferred ones. If you've used an Oculus device with OpenXR on your PC and then later use a Vive/Index, chances are it's still set to use Oculus as the OpenXR runtime. OpenXRExplorer removes the guesswork or diving into environment variables 🙂

[glad sedge]

I noticed that using only oculus link, the controls in the VRTemplate are not working except for correctly displayed movement of the controllers. Grabbing does not work and teleportation only aims to the map origin.
When additionally using steamVR it seamed to have fixed that problem, but i am developing for a few weeks now and the above described broken tracking happens A LOT when simply developing in engine. E.g i start the engine, test something in VRPreview...everything is fine and works... i develop for a bit, play VRPReview again... suddenly no grabbing and only teleporting to map origin. Butten presses and other stick tilt blueprints work fine though.

To describe better how i connect my quest: Start quest-> connect to pc -> establish oculus link connection -> start steamVR via steam, quest goes to steamVR home automatically-> start unreal -> VRPreview button is enabled.

[hallow knoll]

If you can I'd suggest to update to 4.27.2. I updated the VR Template to not rely on GetMotionControllerData, which is the function that fails sometimes when the VRPawn blueprint is opened in Editor (close it and the problem should go away)

Also, make sure you're using the Oculus Runtime when you're working with Quest through Link (see my little PSA above)

[glad sedge]

I just tested to play VRPreview agian after restarting unreal and closing steamvr and only using oculus link. Seems to work fine controler wise

[glad sedge]

On a sidenote, this is what i enabled in my plugins. When i also enable "Oculus OpenXR" as well, packaging fails. With the plugins as shown in the picture, packaging works fine. No problem for me, cause i have the top one disabled, but just letting you know.

[distant nest]

When you enable Oculus OpenXR you're supposed to disable Oculus VR

[glad sedge]

ah thanks, did not know that. since i am only using vr though, i guess i will stick to oculusVR

[distant nest]

Oculus VR is the old system that's getting dropped, so you probably want to move to OpenXR if you care about the future of VR

[glad sedge]

Oh! Well in that case u guess i should switch then.

[blissful bear]

Until Apple come along with there own API.

[distant nest]

That would be sooo apple to do that

OpenXR has been a big change, I'm still struggling to get our build system to properly handle some of the off-brand headsets that don't have the best OpenXR implementations. Hopefully beyond 4.27 things will all be ironed out.

[little marsh]

Anyone here ever experienced choppiness with the Vive face tracker? The tracker behaves properly on the computer I build on but updates abruptly on any other.

The runtimes are the same.

[hallow knoll]

The VR Template is only designed to work with the OpenXR, and OculusOpenXR plugins enabled. SteamVR and OculusVR should be disabled. SIDENOTE: If you're working in 5.0-Release branch on GitHub or for some reason are reading this after 5.0 has been released: ||OpenXR and OculusVR should both be enabled, and in Project Settings -> Plugins -> OculusVR you can set which version of the OculusVR plugin you want to use (OpenXR or Legacy)||

[little marsh]

The fix was switching from USB 1.0 to 3.0

[glad sedge]

I think i have to talk to my teacher. This seems like a lot of stuff that i was taught wrong or at least not up to date🙈

I will try and see if it changes anything

[distant nest]

This is new as of last August on 4.27. Game dev is a moving target, it's a part-time job staying current.

[reef scarab]

Does anybody know if LAN multiplayer is possible on the Oculus Quest 2? I just tried it out, and am getting create session failed. Joining session via IP Address also does not work. I do get a session to pop up when using Find Sessions, but joining that fails as well. About to give up on this one...

[glad sedge]

As mentioned earlier, when enabling the "Oculus OpenXR" plugin, i am not able to package anymore because there are a bunch of different Errors in ...\Intermediate\Source\myproject.Target.cs. Never touched that. Several CS1519, CS1514, CS1520, CS1002, CS1022. Mostly "invalid token" errors.

[jade kettle]

To be honest, that sounds like such a bodgy solution... I love it!

[glad sedge]

VR Plugin constallation to check if packaging works:
Oculus OpenXR✅ , Oculus VR✅ , OpenXR✅, SteamVR✅ -> Packaging working❌
Oculus OpenXR❌, Oculus VR✅ , OpenXR✅, SteamVR✅ -> Packaging working✅
Oculus OpenXR❌ , Oculus VR✅ , OpenXR✅, SteamVR❌ -> Packaging working❌
Oculus OpenXR✅ , Oculus VR❌, OpenXR✅, SteamVR✅ -> Packaging working❌
Oculus OpenXR✅ , Oculus VR❌ , OpenXR✅, SteamVR❌ -> Packaging working❌

The one working setting seems to have no problems in VR though. So i will stick with that for now

[distant nest]

It works incredibly well. Just cut some holes so that the HMD cameras can see out of the box, put a post-it note over the HMD occupancy sensor and you're good. The biggest problem is that it's cardboard and my dog is a recycling enthusiast.

[hallow knoll]

For LAN I generally just add ?listen to the OpenLevel function, and then connect directly using the IP of the host. Quest 1 had no problems connecting to PC, Android, or another Quest and I doubt Quest 2 would be different 🤔

[hallow knoll]

If you just create a new VR template and hit package are you getting the same errors? I would close your project, delete the intermediate folder, then start the project and try to package again

[glad sedge]

I tried the deleting intermetiate folder, did not work

[hallow knoll]

If you keep the Quest plugged in you can debug it in realtime using the Device Output Log - check to see what errors you're getting

[fathom temple]

@glad sedge I have no trouble packaging with that last line of your matrix.

[hallow knoll]

Are you working from source or binary (launcher) version of the engine? Either way I'd test with a new VR Template project to verify if it's the project or engine that's causing issues

[idle osprey]

You might try without the VR template, too. I don't use the template and I don't think I've ever had a problem with packaging.

[hallow knoll]

The Template doesn't typically have issues, there's something funky locally

[idle osprey]

In 4.27, I should say. I stopped trying to use 5.

[glad sedge]

Just creates a clean vr template project. Default settings for plugins were oculusopenxr and openxr enabled... packaging not working
The error is different this time though.
Cant find NetFxSDK install dir; problems with swarminterface should install .net feamework 4.6.0 or higher

[hallow knoll]

How did you install the editor?

[glad sedge]

Throufh the Epic games launcher

[hallow knoll]

Can you package a blank project?

[glad sedge]

Yes

In a blank project oculus vr, openxr and steamvr are all enabled by default. Thats the one setting that works anyways

[distant nest]

If you're getting a NetFxSDK error then you need to install the .net runtime via visual studio installer

[glad sedge]

Currently checking what i have

[glad sedge]

Is it important to do that via Visual studio? I would have just downloaded it from Microsoft

[distant nest]

Honestly not sure. VS has a package manager which does it for you, I'm not even sure if you can download it raw 🤷, might work fine if you do. But I'm assuming you followed this guide at some point? https://docs.unrealengine.com/4.27/en-US/ProductionPipelines/DevelopmentSetup/VisualStudioSetup/

[glad sedge]

I did not follow that guide.
I use unreal since a few months and know visual studio only through 6 years of unity development.
I also just used blueprints until today. Never used cpp in unreal.

But since i see a difference in the dowloads for running and developing apps with .net i will just do it via the vs installer

[distant nest]

Well this might not be your only problem, but this (the instructions) would be the minimum setup I'd expect a dev machine to have to be able to produce builds.

[glad sedge]

Waiting since 30 mins for the vr template to finish shader compiling...

2k shaders to go... i wonder why the priority is low when ressources are available

[glad sedge]

@hallow knoll @distant nest After 1 hour waiting i successfully packaged the vrtemplate. I installed the latest and recommended version of .net (4.8) via visual studio. When connecting my quest via link the quest got updated. Not sure if it was a super unlikely coincidance with an oculus update or the .net did something to my quest. But i can run the packaged VRTemplate project without problems. The spawning in the ground when packaging issue i mentioned way in the beginning was fixed and even the controller orientation when picking up the guns got fixed. (they were on a weird wrist angle before)
Unfortunately my personal project does still did not want to package using only Oculus open xr and openxr enabled, but the problem is still the invalid tokens at ...\Intermediate\Source\myproject.Target.cs.
So i went ahead and tried to have a look at what the problem might be.
🙈 🙈 🙈 After another hour i finally fixed it.
To be more general, i wrote ...\Intermediate\Source\myproject.Target.cs being the problem file... but the actual filename was this ...\Intermediate\Source\Murmur_VR-Ready.Target.cs. "Murmur" being the game title i am working on and VR-Ready is my team name. This was also how i created and named my unreal project initially. As i was looking into the file i noticed that the "-" messed up the Class name recognition resulting in invalid token errors. After changing the project name to a simple name without "-" and deleting and recreating the project folders... the problematic file did not even exist anymore. I can now package and run my game without any problems.

TLDR: Install .net 4.8 via visual studio and the "-" character is forbidden in unreal project names.

Thank you a lot for your support @hallow knoll and @distant nest

Here a picture of the naming issue

After this months long hassle i feel like writing an article about this so people are informed.😅 But also i though high .net versions would be pre installed on win10.

[stray sundial]

Not sure if this is the place to ask this question. Anyone run into problems trying to use action "cast to bp motion controller"?

[void parrot]

Anyone know why VR controller overlap grip would be working perfectly fine in editor and on a Windows build in both Oculus and SteamVR mode but not overlapping/gripping in a Quest build that averages about 50 fps?
Its still not making any sense, I reverted to the original control scheme we had for PCVR and for some reason it just refuses to work on the Quest 2

[void parrot]

You've gotta get the AnimBP from the Skeletal Object attached to the actor
So it'd be Cast To Actor > Get Skeletal Mesh > Cast to Brute_Anim_BP

[stray sundial]

thanks for the response. heres a clip of my screen compared to the tutorial. he types it out and finds it but i dont see it

[void parrot]

If you have a class called BP_MotionController then you can use it, otherwise see what your class is called. The Motion Controller as far as I know is just the class that contains the VR Controller + Hand

[jaunty wadi]

Hi All, working on a VR project and we are using OpenXR, with Oculus OpenXR enabled and the OculusVR disabled however, it seems that we are losing access to the Oculus Library functions if we are not using OculusVR plugin. Wondering if this is worth it? What is the general opinion on this? Thanks

[tired tree]

@glad sedge historically the engine version number also causes problems in project names, I haven't tested it in several versions but people kept naming their projects after the engine versions they were in and causing compilation issues

[hallow knoll]

If you're planning on multi-device support, OpenXR is the way to go. However, if you're only targeting Oculus devices and the Oculus store, and you're planning on shipping soon-ish, the Native OVR plugin is what you want. In 5.0 the OculusOpenXR plugin has been removed as Oculus rolled their OpenXR support into the OculusVR plugin. In Project Settings → Plugins → OculusVR there’s now a setting to select which “plugin” you’re using: Legacy, OVR OpenXR, or Native OpenXR:

All of the features available in the Legacy OVR plugin doesn’t have counterparts in OpenXR yet and that’s why you’re still seeing the Legacy OVRPlugin as an option.

What this means is that you get all of the Platform (read: Oculus Store) features and the OpenXR API for Oculus in the OVR plugin

The OculusOpenXR plugin was a stopgap for OpenXR support on Quest before the native OpenXR plugin supported a bunch of Android related stuff

In 5.0-release branch on github you can now package and launch on Quest with OpenXR being the only enabled VR related plugin 🙂

(however once again if you're planning on shipping soon-ish I wouldn't do that as it's missing some features like Fixed Foveated Rendering)

[tired tree]

@hallow knoll any news on the hand tracking XR extension working with oculus in engine?

[dreamy ivy]

Last live stream before I go on leave for a month. Wasn't sure what to work on so thought we could do some more AI or movement stuff.

https://youtu.be/X2_otdPGaU0 Why not drop by.

[neon geyser]

Small question, when I'm not using the tick of an actor I always disable it. There's also a tick per component, is it also necessary to disable it?

[hallow knoll]

AFAIK we're still waiting

[gray bane]

Hello,
Has any body tried to login using Oculus authentication. I am trying to use Subsystems but they aren't working

And if it does, does it show Oculus's own authentication UI or do I have to make my own

[cerulean pasture]

Hey, around last week I asked about hand gestures and finger placement not working in VR. I tested in 4.26, they work fine. I tested with 4.27, and they don't work. They also don't work on a packaged build in 4.27; I'm wondering what could cause this. I've reinstalled the oculus software, and rebuilt the UE4 4.27 source code a few times now

[ivory magnet]

idk why but I can't get my project to run on quest when vulkan is enabled

it refuses to work unless its openGL

[coral swallow]

it might be due to the XR plugins and components conflicting with the regular oculus and steam things

[dry fjord]

my landscape texture is dropping resolution radically on quest 2, and sometimes displaying using nearest-neighbour sampling randomly. the device profile is set to export full res textures and I've set them to never stream. is there anything else I can check to make sure that it stops downressing?

[primal sky]

Remove the mip levels and/or force it to only ever use the highest one

[rocky condor]

Hi all. I made a VR Grip Drag Rotate movement implementation that I wanted to share with the community. I went ahead and stripped it out of my project and included a little readme with steps to add it. I'll add the Git repo link here. If anyone wants to check it out and use it, feel free. If you're able to make any improvements or know how I can get the scaling to work please let me know. I tested to make sure it works using 4.27.2 and my Quests (1/2) , works with the VR Template as a base. https://github.com/KavanBahrami/UE_VR_Locomotion_GripToMoveRotateScale

[rocky nexus]

vulkan works for me with oculus source build

[coral swallow]

is there a way to make a component ignore the collisions of a specific component / actor or do i have to get creating on how I setup collision channels?

[maiden willow]

Jonathan has a video specific to that

[maiden willow]

And then I realized we weren’t in his server. GDXR on youtube and here is the link: https://youtu.be/4g5IUmx7osg

[coral swallow]

oh right ive watched a good few of his videos for my project lol. I'll have to check this one out. Thanks!

[dusky arrow]

Doing a project in UE4 and I see it is recomended to activate stereo instancing - is there any downsides to this? I have read the benefits but do not see any mention of any restrictions or problems it can cause? For example what are the cases when I would not want to use S.I?

[tired tree]

@coral swallow there is a plugin on the marketplace that implements physxs collision filtering to ignore only between two objects, I also have an open source implementation in my plugin as well

But that is generally if you specifically need just between two, as in some cases collision channels just don't handle it well enough

[ashen knot]

I am making a VR archviz project for quest 2, and came across this video, https://www.youtube.com/watch?v=_GT0KtzPRBA&t=21s, how can I achieve results similar to this guy, especially in the lighting and reflection dept.?

[hard mantle]

Looks like everything is probably fully baked, with that one

[exotic mango]

Does anyone know how to increase the number of max movable spotlights / point lights higher than '4'. The setting is under "Mobile Shader Permutation Reduction"

[hard mantle]

Mobile is only applied for mobile targets- it should be something like 16 on consoles and desktop

[exotic mango]

Yea im developing for the quest 2 the lighting looks good on the editor view but when I build it to the headset the lights start flickering

not all of them just a few I assume those are the ones that put it over that threshold

[jovial violet]

Hey all, sorry if this has been asked before but my game for quest 2 crashes to home immediately when I try to launch it, can someone help me please

[jovial violet]

I package successfully but the game just closes to home screen immediately after the initial quest loading screen

I've disabled mobile hdr and multi-view and tried with both on or off individually. I've tried multiple android versions (from 21 to 32) to package for. All my levels are in the package array. I tried debugging but I can't find any fatal errors but it does show that my game closes just after booting up. It's just weird I've tried so many different things..

I've tried vulkan only, open GL only, arm64 only etc..

I've followed quite a few recommended quest 2 setting tutorials from different sources and nothing just seems to be working

[jovial hamlet]

did you look at the logs during the crash?

[ivory magnet]

Does debugGame not provide logs?

Having trouble locating my quest logs for crashes and issues with subsystem

nvm figured out DeviceOutputLog

[rocky condor]

@jovial violet did you set up oculus entitlement? If so, the default setup quits if you're not entitled, so you need to approve the data agreements on the dev site - can cause the immediate quit issue https://developer.oculus.com/manage/applications/[YOURAPPID]/data-use-checkup/

[ivory magnet]

me?

if so yes

I do this in the level blueprint of my "boot" level

[rocky condor]

sorry, no i was responding to the person just above you.

[velvet panther]

I am having problems getting my Oculus2 controllers to work in the 2.7 demo scene. I can teleport around both with stick and button and use the menu on the right controller. But I cant pick things up. Is this supposed to work out of the box or is it something I have to do to set it up?

[glad sedge]

Maybe check your VRPawn blueprint and see if any warnings about not setup input is shown

like this:

[velvet panther]

I see no such errors. When I run the VR mode where you can edit in real time every button seams to work perfectly. But when I VR preview it does not. I also tried with vr content from the marketplace specifically stating to work for 2.7 and with quest 2. I have tried to package it too but it same result. I must be missing something some where.

have changed this between oculus and steamvr too and switched plugins to all combinations possible with no better result.

[jovial violet]

Hi, I did see something about this in the logs and I have no idea what it means. How do I set entitlements please?

@rocky condor I'm just sideloading it myself atm

[rocky condor]

@jovial violet https://developer.oculus.com/documentation/unreal/ps-entitlement-check/

[jovial violet]

I'm just reading that now haha Thank you 🙂

if this works I'll report back

[jovial violet]

So just followed the info there and it seems this entitlement check is only for checking whether someone obtained this app through the store by legal means. I didn't have anything regarding this initially since I haven't built from a template or anything so I'm not sure on how it would affect my game running on the headset if I'm sideloading it myself. What's confusing is that it's asking me to grab the playerId for verification when I personally don't need any of this. For me to be able to get the playerId I need to give a good reason for it in the 'my app' section under 'API'. The only reasons available are for things like achievements and other unrelated stuff. so I haven't requested this either.

Could this really be why my app is just immediately closing down? I have to request players Id so be able to give entitlements?

@rocky condor

Oh, and for some reason, I don't know if this is related, but I cannot select 'amv7' support. It's just greyed out

I'm stuck with arm64

[jovial hamlet]

You don't have to verify entitlement for Oculus apps. You only need to do it if you use the oculus platform services like achievements or leaderboards.

[distant nest]

What's your reason for wanting to build armv7?

[jovial violet]

I just wanted to test whether armv7 build would work over the arm64. I'm just trying to trouble shoot. I'm on my last test right now by starting a completely fresh VR project from the oculus ue4 build and seeing if that runs. If it doesn't, but the build is still successful then I think it's down to the engine build because everything else seems to be consistent with the settings and setup everyone else does

There is this one issue though, this oculus ue4 build doesn't allow me to choose quality settings and always gives me this message:

but the plugin is actually there and is enabled

so I don't know what that's about

[distant nest]

That sounds like a full stop situation, figure that out. Maybe do an engine installation verify and see if there are some files missing

[jovial violet]

I can't do that since this is a build from github but you are right I've just noticed that specifically 'oculus openxr' plugin is not there

just the openxr ones

[distant nest]

UE4 or UE5?

[tribal lintel]

check this out https://www.youtube.com/watch?v=DHmuhAjLZfw

[jovial violet]

ue4

v2.47.1 by oculus

4.27.1*

lol

[distant nest]

That's going to be an issue for sure, if you don't have the OculusOpenXR then you either need to get it or disable OpenXR and enable the old OculusVR plugin

[jovial violet]

interesting I'll do that now actually

test the old oculus vr plugin

[distant nest]

Just curious, what's in the oculus branch that you want?

because 4.27.1 is a hot mess for VR

[jovial violet]

it was a recommendation by GDXR to use and comes with the new oculus spacewarp feature

[distant nest]

News to me, the spacewarp feature only works in OpenXR, not surprising. Are you following the settings here under How to Enable AppSW in App? https://developer.oculus.com/documentation/unreal/unreal-asw/

[jovial violet]

Yea this is how I set it up

I followed that

I'm trying a build now, after this I will use my standard 4.27.2 build that comes with the launcher and see if I can get a successful build

[distant nest]

Looking at the latest Oculus commit in 4.27, they've done something kind of odd that they didn't publish. They deleted the OculusOpenXR plugin and they've now re-purposed the OculusVR plugin with an internal name of OculusOpenXRHMD. So for project you're in, when on this Oculus branch, you want to remove the OculusOpenXR plugin and put OculusVR in its place. And then leave the OpenXR plugin enabled as well.

[jovial violet]

😮

right

thanks lemme take a look

yea I can see in the folder for oculusopenXR there's no files

You think I should copy/paste everything from openxr into there?

[distant nest]

no no

Just open the project, edit plugins and make sure OculusOpenXR is off and OculusVR + OpenXR are on

Or edit your .uproject file directly, same result

[jovial violet]

I see, well they already are. In the project itself when I look through my plugins there's nothing with the name 'OculusOpenXR' in there anyway

[distant nest]

The message you got about the plugin not existing is because the plugin is listed in your .uproject file, but the UI won't show it obviously now that I think of it

[jovial violet]

Ok so just a matter of editing the uproject or just hitting yes to continue

[distant nest]

yeah

[jovial violet]

ok I'm getting something different now

just an endless loading screen which is new

it used to just immediately quick to home

This is the live log for it

[distant nest]

Sometimes it can be more useful to look directly at the UE4 log to see what it's trying to do

The full system log can be a bit noisy

[jovial violet]

I haven't launched it from within the engine unfortunately, this is a sideloaded build of the game

[distant nest]

You can grab it with adb

If your game is named MyGame it would be:
adb pull /sdcard/UE4Game/MyGame/MyGame/Saved/Logs/MyGame.log

[jovial violet]

oh right nice, do I execute that with the oculus developer hub?

[distant nest]

adb is a debug utility provided by the android sdk, if you followed the epic install guide, adb should be in your system path, so dropping to a command line and typing adb devices should show you the headset connected

[jovial violet]

I do have that yea I'll check now

looking at the log seems like there's a lot of weird stuff happening

look at this bit

[2022.01.23-20.39.10:063][ 0]LogAndroid: VulkanRHI will NOT be used:

I have checked use Vulkan in the project so I don't know why it's doing this

[distant nest]

ahh, maybe you have a DefaultEngine.ini setting to disable it

[jovial violet]

and then this here specifically:

LogInit: Display: Project file not found: ../../../DavysTreesQuest2/DavysTreesQuest2.uproject
LogInit: Display: Attempting to find via project info helper.
LogUProjectInfo: Found projects:

why is it trying to find that uproject file?

[distant nest]

That's a new one, could be debug log related

[jovial violet]

oh ok

well I've found that in the engine.ini vulkan SM5 is set to false

[distant nest]

You don't specifically see one r.Android.DisableVulkanSupport?

[jovial violet]

no nothing like that

just did a search

[distant nest]

And you built specifically for vulkan astc?

[jovial violet]

yea

from within the engine, the engine build itself is provided by oculus via their github so whatever that comes with has been built

[distant nest]

I'm totally unfamiliar with that, there might be an actual Oculus "Use Vulkan" checkbox you have to hit, they do stuff like that

maybe just open project settings and search for Vulkan

[jovial violet]

alreach checked

already*

I'm doing another build since setting the vulkan SM5 thing to true

[distant nest]

sm5 is for desktop

[jovial violet]

ah

well

I'm screwed..

[distant nest]

Oculus doesn't have settings in there about a "legacy" plugin?

[jovial violet]

I'll check now

[distant nest]

Or oculus specific XR?

Can't help much, never used that branch so can't say if it even works. I'm in 4.27.2 epic branch all day

[jovial violet]

You know I think I'm just gonna migrate this over to the core engine and see what happens

[distant nest]

But logs seem to indicate that there's a deliberate setting turning vulkan off

[jovial violet]

feel free to take a look if you'd like:

https://we.tl/t-KzfyBHZ0Sb

put the logs in there

I don't know what I'm looking for exactly but nothing sticks out

[2022.01.23-20.40.56:957][ 0]LogAndroid: VulkanRHI will NOT be used:

[2022.01.23-20.40.56:957][ 0]LogAndroid: Vulkan SM5 is available but disabled for this device.

does this mean anything?

[jovial violet]

Sorry I'm not trying to spam. This seems to be the biggest and most repeated error in my build output log

I don't think that's enough to stop a game from actually running though :/

[dry fjord]

I've forced my landscape textures to use mip 0, forced them to never stream, forced them to do everything possible, ensured that they're not limited by device profile, but I'm still seeing massively low detail textures using nearest-neighbour sampling, and ONLY on the landscape.
what could be causing this?

[ivory magnet]

@jovial violetare you verifying entitlement?

[jovial violet]

I did but I don't have data use checkup enabled so I can't verify user ID. However after researching this I shouldn't need to do any of this since I'm just trying to play my game on my quest 2 for development purposes. It's not going to be released publicly

[distant nest]

Hey I'm in and out, but what I see:

[2022.01.23-20.40.56:883][  0]LogInit: Applying CVar settings loaded from the selected device profile: [Android]

So the default android profile is disabling vulkan. Maybe you have some odd settings in a Config/DefaultDeviceProfiles.ini?? Or maybe Oculus fubar'd the default device profile. You can view this in the engine.

[rocky nexus]

perhaps low precision material

[dry fjord]

hmm could be. where do you check that?

[jovial violet]

Thank you man, you didn't have to check all that I know it's a lot. I'll take a look and see what I find 🙂

I don't have a defaultdeviceprofiles.ini in my folder

[distant nest]

You'd only have on if you had overridden any settings, if you haven't overridden then you're taking defaults that are defined in the Engine/Config folder, maybe BaseDeviceProfiles.ini. It's generally easier to look at them via the engine: Windows->Developer Tools->Device Profiles

[jovial violet]

thank you 🙂

if this works I'll be so happy

[distant nest]

When I load a project on my quest 2, I see my logs load a profile called Android_Adreno6xx_Vulkan

[jovial violet]

just reading some unreal documentation and it does say it will load that profile by default: Android_Adreno5xx

[distant nest]

5x is the quest 1, 6x is quest 2

[jovial violet]

just gonna have a look through these now

[distant nest]

I don't have Oculus Quest entries in mine, must be some secret sauce in the oculus repo. Why your device isn't loading them though 😕

[jovial violet]

yea this is a real odd one

[distant nest]

The setting is correct, the problem is that the app is loading the Android profile instead of the device-specific one

oh hold up, what's this

[2022.01.23-20.39.09:993][ 0]LogModuleManager: Warning: ModuleManager: Module 'AndroidDeviceProfileSelectorRuntime' not found - its StaticallyLinkedModuleInitializers function is null.

[jovial violet]

I think this is it

[distant nest]

well you're missing the module that matches device profiles to the device

[jovial violet]

oh am I

no way

how am I missing that?

[distant nest]

🤷, never seen this before

[jovial violet]

why me

lol

this is a super important project

and I need it to be playable on other people's quest 2 for demo purposes. I'll look into this module issue but thank you so much for this

I think we just narrowed it right down

[distant nest]

AndroidDeviceProfileSelectorRuntime is yet another engine plugin and maybe it got munged in the oculus repo

[jovial violet]

oh no

[distant nest]

One simple workaround could be just copying the properties of the Quest 2 device profile into the Android profile since that's what will get loaded by default. But if this is having issues, who knows what else could also be broken, it would likely just kick the issues further down the road.

[jovial violet]

facepal,m

[distant nest]

lol, give that a try

[jovial violet]

imagine if it was just that all along..

let's see

building now

[distant nest]

You could disable the oculus online subsystem if you want to get rid of that mess of warnings

[jovial violet]

good idea actually

doing that now

[distant nest]

I always disable it when I'm prototyping

[jovial violet]

good idea honestly, I shouldn't need to be checking user Id's n stuff while I'm testing

[distant nest]

I dunno, I have a good feeling about this

And I think if Han Solo were here, he'd agree

[jovial violet]

If this works, it's probably worth highlighting somewhere as something to check

haha

yea he probably would

I don't know if this is worth mentioning but:

"LogBlueprint: Error: ProxyFactoryClass null in K2Node_AsyncAction /Game/Levels/L_PersistentLevel.L_PersistentLevel:PersistentLevel.L_PersistentLevel.EventGraph.K2Node_AsyncAction_0. Was a class deleted or saved on a non promoted build?" I just got a spam of these in the output log

anyway I'll wait to test the build first

it might be nothing

[distant nest]

sounds like you might need to take a look at level blueprint in that map, make sure it compiles, save it. You didn't perhaps have the project loaded in a newer engine and then loaded in a lower version?

If build fails, just keep grabbing logs and we'll continue down the rabbit hole .

[jovial violet]

So what happened was I built this in 4.26 first, then migrated to 4.27, then to 4.27.1 and then 4.27.2

but the oculus repo is 4.27.1 still

so I opened it with that and it have to convert everything to that version

seemed to work fine and it all builds fine

but I never got this game built and running before using the oculus repo anyway. I always used the valve index for testing

[distant nest]

It's possible, if you saved in 4.27.2, if there were any changes to binary format between 4.27.1->4.27.2, it could be causing the issue. I don't know if Epic has a policy about that for patch releases.

You would have had to explicitly save. Otherwise it's also possible you have a bunch of dirty intermediate files from the newer engine 🤷

[jovial violet]

I can double check that, but I did delete the original intermediate after the migration to the oculus repo just for a clean start

however, this version of the project is almost double the size of the one before the migration and the intermediate folder is huge

almost the build time this time around is taking much longer

I think this is a good sign

[distant nest]

quality takes time, we can hope lol

[jovial violet]

I'm hoping real hard rn

haha

[distant nest]

I gots to run for a few hours, will check in when I'm back 🤞, good luck

[jovial violet]

thank you 🙂 We're closer. I got into my first level which is meant to load the splash screens. What happened was the screens didn't display but the widget was there. My hand models were also doubled up in the left lense but non in the right lens at all

[dry fjord]

it was this, thanks 🙂

[jovial violet]

@distant nest Good news, the game now runs! I got into the first level. It's just splash screens playing a simple animation for the studio logo. It crashes loading for the next level though which is the main menu that is based in a small 3D location. Here's the log, very big error at the bottom

https://we.tl/t-RW8yNhFevW

I'm gonna try and figure this out myself.No rush but when you get back, any advice would be much appreciated 🙂

[distant nest]

Well 💩, vulkan crashed. Unfortunately 4.27 has a few vulkan issues that are still being worked on. This call stack doesn't look like the other 2 crashes I was getting. Unfortunately something like this, the best you can do is try to single out the object in your level that's causing the renderer to die. A mix of adding debug, symbolicating the stack trace to dig deeper or just by starting to strip back features and actors until you get a baseline working level.

You might start just by puting your level into Vulkan Preview mode in the editor and just see if any shader issues come up. You might have some ridonkulous shaders in there or something.

[jovial violet]

I do have a pretty intense shader in here tbh

thank you I'll check that now

How do I do just a vulkan preview?

[distant nest]

under settings, preview rendering, don't have it in front of me, same area where you change from epic quality etc, you can change from desktop SM5 to vulkan

[jovial violet]

ah that one I got you

thanks

I remember

Do you happen to know if the quest2 has issues with level streaming and loading splash screens for the loading screen?

[hard mantle]

Anyone hitting crashes previewing in VR on ue5-main, I've got a workaround and am trying to investigate why the workaround is necessary

This should get you back up and running until I've finished investigation, or an Epic dev gets back to me on what's going on here

[distant nest]

Splash screens are fubar'd in 4.27, I'd avoid them

[jovial violet]

that makes sense. I've just managed to load into my first real level. So I turned off loading splash screens originally and tried a vulkan build and still could load my main menu level but after changing over completely from vulkan to openGL I get into my main menu level but unfortunately I spawn in at z=0.0 while my level floor is at z-100.0 height. I also noticed that in my left lens it only renders some shade of solid grey while everything else has rendered in my right lens just fine

bit weird

oh and my ui widget was flipped horizontally. I'm gonna test some things. I can't believe how awkward this has become but I'm closer than ever now I can't give up. I really appreciate all of your help so far @distant nest thank you

[paper egret]

Hey guys!
Total noob here in terms of UE, i am a graphical designer and wanted to test out the VR game mode in Unreal engine 5.

I am using a Rift S, steam VR is enabled, i also enabled VR mode in the editor preferences and also checked the "start in VR" in project settings.

However, when clicking on play, it does not load me into VR, i tried and find some tutorials online on how to link your VR headset to UE5, however, no luck.

Is there anything i need to do that i am forgetting?

Thanks in advance,
Revi

Ah! I just checked out the pinned posts, seems like someone made a guide on this, awesome 😄

[hallow knoll]

@paper egret If you're using a Rift S you should use the Oculus software and not SteamVR. If you're using UE5 Early Access and your VR system is properly configured, just create a new VR Template and you'll see "VR Preview" available in the drop down

No other settings are required! It's important to know the difference between "VR Editor Mode" and "VR Preview". VR Editor Mode is a mode that lets you use the editor to build your level in VR. VR Preview is how you test your VR game.

[hallow knoll]

UE-Main is not being tested as thoroughly as the release staging branch: https://github.com/EpicGames/UnrealEngine/tree/ue5-release-engine-staging

[paper egret]

Thanks mate, appreciate it

[sleek sandal]

So i have this weird "Bug", i think, i have been trying to solve since a week ago, basically the first image is the view that i have in the Unreal 4.27 editor, but when i package it to my Oculus Quest 2, all the lightning goes crazy and the lightning, shadows and color changes, i don't know if there is a setting i'm missing, anyone knows what is happening with this?

[idle marten]

Hello everyone! I'm following a tutorial to setup a project for Quest 2 with UE4.27.. however.. I have a Quest v1... what shortfalls should I be ready for?

[granite idol]

You guys ever get the issue where when you press play via VR preview, nothing happens? I'm on Quest 1, connected linked to PC, it's not grayed out

nvm, it worked

[hasty granite]

yes, i also sometimes get this issue

[granite idol]

For sure, seemed like I had to do things in right order

[hasty granite]

Hi all, i am getting this issue. When i turn on oculus link , i get this loading screen forever. and cant enter oculus link. And on oculus pc app it says hardware not found, but its shows connect. I tried to update, uninstall insall, restart everything , but no luck

anyone can help me please, DM are also allowed

[hallow knoll]

The rendering path on PC is different than it is on Quest. You have to enable Vulkan Preview Rendering Level in editor to simulate what it's going to look like on your Quest: https://docs.unrealengine.com/4.27/en-US/SharingAndReleasing/Mobile/Previewer/

[hallow knoll]

Which tutorial? The only difference between the two should be performance-wise

[sleek sandal]

I will try that 🤯 thnx

[trail shale]

Installed editor on new machine is fine, the controllers track and steamvr but they do not track in the editor. They track in a build just fine though - what am I missing I don't believe I've even done anything to any blueprint

Steam says I am missing an action manifest

[idle marten]

@hallow knoll I was looking at the API level and it seemed to be different.. but I was definitely looking at old posts on forums... so I should just be good to follow the Quest 2 tutorial then..

just trying to make sure I set up android studio right.. and all the stuff related to just building to quest.. I followed a tutorial a few years ago but it was in 4.24, which didnt use the same android studio setup.

thanks!

https://www.youtube.com/watch?v=XR2t_PMQbn4&t=984s this tutorial

the most recent thing I saw on youtube.

[wheat holly]

Hi all, maybe a silly question but do we need to have the SteamVR / the Oculus plugin enabled when using the OpenXR plugin? I can't seem to get it to work without on 4.27.2 on my Index through Steam.

[hallow knoll]

@idle marten the VR Template in 4.27 (and later) doesn't require any changes as long as you have the android development environment for 4.27 properly configured (nothing different for Quest): https://docs.unrealengine.com/4.27/en-US/SharingAndReleasing/Mobile/Android/Setup/AndroidStudio/

[hallow knoll]

If you want to use OpenXR you should keep the other plugins disabled

If you have SteamVR/OculusVR enabled they'll take priority and you won't be using OpenXR

[wheat holly]

I tried disabling both and running just with the "OpenXR" plugin, but my headset stopped tracking and so did my controllers. I'll try it again I guess 🙂

[hallow knoll]

Have you had an Oculus device installed on the computer previously? You have to make sure that your OpenXR environment variable is set to use the appropriate runtime (SteamVR), and launch it prior to running the editor (it usually works either way for me but to make sure). Use OpenXRExplorer if you don't know how to configure the environment variable: https://github.com/maluoi/openxr-explorer

[wheat holly]

Huh interesting, apparently it wasn't using Steam? I guess I must have installed the Oculus software at some point, or maybe it uses the developer system from Oculus for the Quest I have. I currently have the Oculus plugin running as well and now it works fine again.

[idle marten]

@hallow knoll dude thanks! Awesome to know ALL OF THAT lol

[wheat holly]

Neat little tool, thank you!

OpenXR even made my input system work that didn't before xD
I am curious though, can people run into this issue as well with OpenXR enabled? Lets say I put my game on Steam, can people run into these issues where they need to set their environment variables?

[distant nest]

I'm sure it won't be any worse than the mess of the early days of oculus + steam

as a PC VR user, you just got used to dealing with a certain threshold of shenangins to get stuff to work

[wheat holly]

I would expect there to be a few issues yeah, although I'm sure they'll get fixed over time. But just curious if this a general thing that can happen with openxr or only when using the editor 🙂

[distant nest]

I think it's going to get better over time. Right now it's all based on a priority list of devices frameworks. In OpenXR, when engine starts up it enumerates OpenXR plugins based on the priorities you've given them. By default it's Oculus > Steam > OpenXR > Windows Mixed Reality.

[hallow knoll]

@distant nest in 4.27 OculusVR and SteamVR plugins are not using OpenXR

[distant nest]

That's the problem in my mind right now. There's no checks or anything preventing my generic android HMD that has its own OpenXR plugin, from binding to the Oculus OpenXR plugin. So you have to re-prioritize during packaging, specifically for that headset.

[distant nest]

I know, I'm talking about the [HMDPluginPriority] in DefaultEngine.ini, I'm abstracting the names of the detected HMD frameworks

[hallow knoll]

Just clarifying "In OpenXR, when engine starts up it enumerates OpenXR plugins"

[distant nest]

Maybe better to say, it goes through HMDPluginPriority from highest to lowest and attempts to bind to each OpenXR framwork listed in priority order.

[hallow knoll]

But OculusVR and SteamVR plugins, in 4.27, aren't using OpenXR at all. I wrote up some details earlier how the Oculus plugin is configured in 5.0 though: https://discordapp.com/channels/187217643009212416/221799478364078081/934126896462069760

[distant nest]

Probably confusion in naming, in 4.27, OculusOpenXR plugin maps to the HMD name OculusHMD

[hallow knoll]

OculusOpenXR is where functionality to package for Quest with OpenXR went for 4.27, but it's now been rolled into the OVR plugin, and the native OpenXR plugin received updates to how it handles android and can now package and launch on Quest 🙂

[distant nest]

That'll be nice. I hope I can eventually build 1 package for both Quest and Pico Neo where I don't have to manually adjust HMD priorities

[hallow knoll]

I've yet to get my hands on a Pico Neo 3, but last time I checked their SDK didn't support OpenXR

[distant nest]

I've only been working with it a month now, but they've had a full OpenXR plugin since I've started. I recently submitted a patch to make some of the input capturing fit more into OpenXR ecosystem, where it only grabs input if it detects the correct HMD name.

[hallow knoll]

If they were OpenXR compliant it should work with our native OpenXR plugin like Quest does, but perhaps there's something missing there 🤔

[distant nest]

It's honestly kind of a mess, the way they did the OpenXR defeats the entire purpose behind Open XR: https://sdk.picovr.com/docs/UnrealXRSDK/en/chapter_two.html

So one challenge of OpenXR is to make sure vendors aren't just breaking everything by doing 1-off implementations 🤣

[hallow knoll]

disable OpenXR 👀

[distant nest]

lol, yes I fell out of my chair when I read that

So basically I ignored most of their advice, fixed the input binding, left OpenXR on and set PicoXRHMD=50 in the [HMDPluginPriority] and that's the working formula with the least amount of ridiculousness for me.

But now, back to unique builds for each device, so net-net nothing gained with OpenXR for our build system. I'm hopeful that the Pico folks will fix things eventually, they are part of the consortium but maybe it'd help at the next consortium meeting to just ask them about this stuff.

[hard mantle]

I'm sort of stunned how much of a difference in latency and smoothness arises switching from openxr to steamvr

The motion controllers can't keep up with my hand, with the OpenXR plugin, but they keep in almost perfect lockstep with the steamvr overlay if I use steamvr

it feels almost as if openxr is polling instead of evented...

[plain apex]

this might be a better place to ask, but im trying to use the oculus quest 2 to control the movement of a camera, ive tried a few things but cant get it to work quite right, ive been able to get it working where it moves in the cardinal directions, but it doesnt move where the camera is looking which is slight problem
So the Forward input is always scene forward, not based on the actual cine camera actor
The Better movement graph isnt working but i believe that is the solution im looking for

[distant nest]

The math is off here. You want basically Delta Location = Input * Right Vector
So get your camera vector, zero Z, then multiply that vector times your input.

[plain apex]

for which blueprint, first or second image?

[distant nest]

The 2nd

[plain apex]

alright, just a note, when i begin play and move the thumbstick nothing happens, ill put a print node to see if its even doing anything at all but nothing happens when i move the joystick

if it matters im also using steamvr, not oculus, because i need steamvr over oculus for this specific thing

[distant nest]

The math is the same regardless

[plain apex]

ok thats interesting, that print result isnt working, so that means nothing is being fired regardless

[plain apex]

gotcha ill fix that

[distant nest]

One clarifying question, I had assumed you wanted to move the cameras location. Are you only trying to rotate it?

[plain apex]

no no, i would like to move it, basically how a FPS character would move

where, the direction they look is where they go based on joystick

its just been a bit tricky to get working with the bp being a cinecamera actor, and the oculus quest controllers

[distant nest]

Got it, ok that's what I thought. Input * Right/Left Vector gives you a Vector. So when you're making a transform, use that as the location and the existing rotation of the camera as rot.

[plain apex]

akin to this?

[distant nest]

Replace Rotation from Vector with a Make Vector

Rotation of cine camera component goes to final make transform rotation

[plain apex]

hm, unless ive done something wrong that doesnt seem to work

i have two inputs that im testing as im making these changes, one i know for a fact works, and the other is what i would prefer to work, one is essentially D pad movement and the other is Joystick

neither trigger the print string at the end

[distant nest]

Get rid of the rotation from vector

[plain apex]

done

[distant nest]

Get rotation of the component

Actually if you are adding relative then rotation should be zero

[plain apex]

I am setting relative transform at the end

all of the nodes currently

i was gonna get that top chain working then clone it to the bottom chain, since theyre the same logic

[distant nest]

Sorry I'm on a phone so node names are fuzzy when I zoom

[plain apex]

all good, ill try to get a better screenshot

that might be better

[distant nest]

If you are Setting relative transform then you need to pass the existing relative rotation of the camera

Relative being the key word

[plain apex]

right, so that would pass the direction im looking in then?

would it be better to split the new transform struct and plug in stuff that way?

rather than trying to make transform

[distant nest]

Righs. Get world rotation is not relative

[plain apex]

ahhh, i see, i can get relative for scene component then plug that into make transform

[distant nest]

Do that

[plain apex]

well this is odd, so the inputs for this are mapped to the directions, up down left right, and none of those appear to even be working, regardless of being plugged in

this is all in the same BP if that matters, but i know that code at the very least moves the camera in the scene, but all my other actions are working sooooo

[distant nest]

Your input bindings sound sus, might need to sort those out

[plain apex]

yea im reloading the steamvr manifest rn

idk why just the thumbstick ones wouldnt be working

ok so now my left right and back work, but the forward does nothing

to be clear, this does nothing

[distant nest]

Why would it? You have a branch hard coded to true that only has the false branch connected...

[plain apex]

most of the nodes are from a youtube video that was showing motion controllers in VR space, i attempted to adapt it for a cine camera, but the axis mapping works like an event tick, iirc the tut left the branch there to know how far the joystick moved, but I can make the axis mapping a toggle of sorts to even see what it does

cuz piping true into the setrelative makes it just jitter a LOT while printing that last string

[plain apex]

got it working

this apparently does the trick

i did some searching and this seems to do the trick, now i just need to make that last mult node a movement speed and ill be in business

[spark cave]

I've been struggling to find this, but is there a good reference for C++ development for VR? All I want to do is figure out if the HMD device is enabled, but all I can find are blueprints

[hard mantle]

Generally, blueprint nodes will have a very similarly named equivalent in C++, and the translation is trivial; you may not find many C++-only examples, considering single-target documentation is doubly effective if blueprint users can understand it

https://docs.unrealengine.com/4.27/en-US/API/ is generally where you'll find them by name- you can narrow documentation searches to API documentation

[spark cave]

I've tried to make that work. I have tried to do the one-to-one mapping, and usually that works, but there is something I am missing here

I've gone thru the api documentation as well, asking here is a last resort

[hard mantle]

Let's try from another angle: what piece is missing? What's the blueprint node that does what you're trying to do?

[spark cave]

I can't find IsHeadMountedDisplayEnabled in C++

everything I have read leads me to using GEngine->XRSystem

but that just gives me an error saying that is an incomplete class

I don't think thats right either way, becuase XRSystem uses HMD vs HeadMountedDisplay

[hard mantle]

return GEngine->XRSystem.IsValid() && GEngine->XRSystem->IsHeadTrackingAllowed(); is how it's implemented, but you have to make sure you're starting at the right time

https://github.com/EpicGames/UnrealEngine/blob/99b6e203a15d04fc7bbbf554c421a985c1ccb8f1/Engine/Source/Runtime/HeadMountedDisplay/Private/HeadMountedDisplayFunctionLibrary.cpp#L29

[spark cave]

So that is my issue, when trying this I get the error `Type IXRTrackingSystem is incomplete, so it won'te ven let me build

[hard mantle]

potentially, it's just being called at the wrong time- before it's finished initializing?

whoa.. Okay, checking

#include "IXRTrackingSystem.h" and it should work

[spark cave]

ahh I see, so my C++ knowledge is what has failed me today 🤦‍♂️

[hard mantle]

(in the .cpp file where you use it)

TLDR: Headers can say "there's a thing here, but I won't tell you its shape- just its name"

Then other headers can come in and explain that shape for you when you need it

"Incomplete type is not allowed" is produced by the C++ compiler when this is used and you lack the info on the type you're trying to access

[spark cave]

okay that makes sense, I see what I was missing there

I still have much to learn lol

[hard mantle]

C++ is an endless language- you'll always be missing something; Generally, this is the secret weapon for figuring it out:

[spark cave]

I always do ue4, but I guess I should just type unreal moving forward

[hard mantle]

try it all

I still write udk half the time

[spark cave]

lol okay, i'll add that one to the arsenal as well

thanks @hard mantle for all of the help here

[hard mantle]

No problem; nothing else to do:

[spark cave]

lol so you have a little time to burn

[hard mantle]

this is the sixth build in 24 hours

apparently RunUAT BuildGraph threw away my entire incremental cache

[spark cave]

oh so it basically is starting from ground zero

[hard mantle]

for the sixth time since last night, yep

[spark cave]

that sounds painful

[hard mantle]

I'm idly browsing used xeon servers as a result 😛

[spark cave]

😆 I guess you might as well

[hard mantle]

god help me though- the varjo xr3

I'm glad I was at least able to set the impulse buy threshold to "any funding toward it has to come from the game, if you want one" 😛

[spark cave]

hahaha yea thats a smart plan. I need to do something similar, but I wouldn't be getting a headset for a long time lol

[olive ferry]

Did someone managed to voice chat using Quest 2 ?

[rare ridge]

Hey guys, I am currently working on a VR project and I want to be able to navigate through the scene without a VR headset as well. Therefore I startet with the VR template and copied the movement logic from the first person template into that (just the WASD movement part). That does work in theory (the MoveForward function gets called), however the character is not moving in the scene. I noticed that it is not even falling to the ground even though gravity is enabled. Any idea why that happens?

Also I noticed that while the VRCharacter (from the VR template) spawns a camera itself, there is the default CameraManager that spawns a camera as well that is not used. Can/should I turn that off (somehow)?

https://media.discordapp.net/attachments/221798862938046464/935468406612824095/unknown.png

[wheat holly]

Does the movement code actually invoke the move method, tried printing out some messages already? Also showing what you did so far in terms of code / blueprints may be a good idea 😄

[tired tree]

tbh sounds like its not spawning / possessing the actual character and he is getting a debug camera

[glad sedge]

Try updating your microsoft .net version. When using OpenXR and Oculus OpenXR or OpenXR and Oculus VR Plugins, packaging and correct controller input failed until i installed the newest version of .net and that fixed it for me. Maybe it helps you too. Or try packaging and see what happens or errors occur

[lapis tide]

Hey Is there somebody that has a lot of experience building apps for oculus quest 2? I'm trying to build my apk and install it but it only shows black and i've been through every corner of the forums but can't find a workable solution. Does anyone else has a similair experience with the quest 2?

[rocky nexus]

Start by checking logs

[lapis tide]

you mean the output logs?

[rocky nexus]

device logs, black screen likely means it is crashing

instaling fresh vr template might be useful as well

[granite idol]

Possible easy question: When looking down in VR, my character slows down. I do want to steer with where I am looking as well. So any clues?

[tired tree]

@granite idol project the forward vector to a 2d plane on XY

otherwise with that setup you are putting in less than 1.0f on those axis's when looking away from level

[distant nest]

^^ It's also equivalent if you zero the Z and then normalize the resulting direction vector, assuming you don't want to move vertically.

[distant nest]

I've been using Vivox for voice chat on the quest pretty successfully

[granite idol]

@tired tree

Like so?

[distant nest]

project is the keyword you might want to google, as in the node project vector on plane

[tired tree]

@granite idol https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Math/Vector/ProjectVectorontoPlane/

plane normal being Z=1.0f

when flying you wouldn't project it

[granite idol]

I'm not worried about that. All I want to do is walk around and if my player looks up or down, I don't want the forward movement to slow down

[tired tree]

i only mentioned it because you have a flight check in that SS

[reef willow]

anyone have any luck integrating OnlineSubsystem (EOS) with HoloLens Platform

[primal vessel]

Yo complete noob here. How would I go about preventing the player from teleporting until a particular time? I've got a character taxiing into a scene on a spline and I don't want to be able to teleport onto navmesh until it finishes

[maiden willow]

Put a bool check in your teleport event "CanTeleport" and if it is false then do nothing

[olive ferry]

Can't find any blueprint about vivox on the project, do you have an exemple, screenshot I can see to get an idea ?

[distant nest]

It's a whole thing. https://docs.unrealengine.com/4.26/en-US/ProductionPipelines/VivoxPlugin/VivoxIntegrationGuide/

[olive ferry]

Yeh I was reading this page but step two got me lost 😢 Select a User ID. Login using an appropriately generated VAT, which can be supplied by the VivoxVoiceChat Plugin. during development.

What is that ?

[distant nest]

Sounds like you skipped the first instruction where you create an account on the Vivox dev portal. All of that stuff comes from there.

[olive ferry]

Ooh I see thank you 👍

Did you set it up using Cpp or blueprint ?

[distant nest]

I do everything in cpp, but I don't think it's required for vivox.

[olive ferry]

Thank you for your replies, you helped me a lot 👍

hi there, i have collision that works on PIE and work on Oculus Airlink ... but do not work when packaged.
Its a thin static mesh ...double side ... with tag... nothing special at first ....
in fact i do not understand what is causing the difference between the PC and the Oculus...
Any idea?

[marsh salmon]

Hi, I'm trying to get help with performance profiling, hope this is the right channel. I'm getting framerate spikes in my scene. I'm looking at both the Session Frontend and Unreal Insights tools. For Session Frontend, all of the costly tasks are reading as CPU stall - waiting for other threads. In Unreal Insights (see image) it's not showing me which specific task is causing the ~40-50 ms frame time. The most costly task is only about 2.8 ms. What am I doing wrong here?

[hard relic]

or maybe complex collision are unsupported or bugged on Android?

Or maybe because it is a splinemesh?

[idle marten]

Hey anyone know what this means? and what needs to happen? I'm tryin to launch on the quest

quest v1 dont know if that matters.

[mystic tinsel]

does this help? https://answers.unrealengine.com/questions/209021/missing-ue4game-binary-failed-to-package-for-win64.html

[mystic tinsel]

I would like to know if there is something I can change to properly test this in the editor though.

[coral swallow]

ive set my character up to make the capsule move along with the players HMD. the only problem is that when coming up to a small ledge, the capusle will hit it and stop as it should when moving with thumbstick, but if i move my head forward slightly i get put to the top of the ledge. How might i go about stopping that

[tired tree]

@coral swallow you would have to inject the movement into the characters movement input instead of just setting location, setting location you skip all of the world collision and step up logic that is normally done in a character. Granted for the world collision you can sweep your movement addition but its still going to cause edge cases

[coral swallow]

i never thought of doing something like that. Thats a pretty smart solution actually. I'll give it a shot thanks!

[tired tree]

@coral swallow well injection is limited by the players max move speed and suffers when already walking so its not perfect

unless you do it in c++

i've mentioned the downsides to the naive location setting to everyone doing it in here but think you are the first one to actually try a complex movement and see it ;p

[granite idol]

Question: When spawning an actor with a widget component in it, it auto starts the widget, but when the widget gets closes, does it also remove the ref of the widget? As in, does it garbage collect on actor destroy? Or is the widget still created in the background somehow? Might be a dumb question

[subtle raft]

I got Oculus Hand Tracking to work in editor, but when packaged it isn't working. No hands are being shown and I don't believe they're invisible because when they were invisible during testing they were still functional. I'm linking to my Quest same way for both editor and packaged.

[hard mantle]

You can get around this by allowing a temporal budget for real-space movement to allow brief bursts of extra speed refilled during times of low motion

[hard mantle]

Try putting debug prints or breakpoints in destruction to get an idea of when, but the GC should be cleaning them up, ya, but only if the pointer is not holding it anymore

[granite idol]

Agreed. @hard mantle

[hard mantle]

I recommend a falloff cap such that if the player uses the budget, a constant-times-proportional factor is subtracted from their max speed and filled back onto the budget with each frame thereafter. This will keep their top speed “apparently” consistent in the case of even a malicious user trying to speedhack in a VR FPS, while avoiding the jarring “capped speed” feeling or potential desyncs in position present if you cap their HMD movement speed purely based on the normal controller movement speed

In other words, if someone teleports immediately across their entire playspace, it’s better to let them than to desync with tracking, so take the cost out by slowing them down for the next few seconds.

You can do more by having a maximum HMD speed limit that’s calibrated to be unlikely to be hit in practice, and applying that cap prior to the movement tick, but that’s not necessary unless you’re making a competitive game where movement matters significantly

[tired tree]

i was talking about the characters max movement speed and if you inject into the movement input naively that you will artifically limit movement

but yeah, in my plugin I have a threshold detection for too much movement in one frame and I cap the player around the human limit, freezing their position for that update, which can happen entirely naturally from tracking loss (intentional or otherwise) and walking around during it.

I also handle the actual movement differently though since its c++, I roll back the movement prior to the CMC update and then play it back as part of the movement velocity

[wicked quarry]

hey guys, would anyone happen to understand this error ? I'm using a MacOSX and am trying to hook nit up to a Quest 2 on Unreal 4.27.2

my sdk is android 10.0
and my ndk is 23.0.7599858

any help would be much appreciated !

[subtle raft]

This is crazy, but apparently Oculus only supports hand tracking with link through the editor...

I can't believe they've done this

They basically have a bool in their SDK that turns off hand tracking through link if not using it through Unreal VR preview

[distant nest]

In Epic Launcher, 4.27, Options, did you install the Android target platform?

[distant nest]

Looking at their OpenXRHandTracking plugin, it looks like it supports both live link and standalone. I haven't used it, but, dumb question, is hand tracking enabled on your quest?

[subtle raft]

yea it works in the VR Preview

[distant nest]

that's different

[subtle raft]

I'm air linking to my Quest in VR Preview

[distant nest]

Quest, when not in live link specifically has a hand tracking setting you need to enable

[subtle raft]

and I operate my Quest with hand tracking in the main menu before linking

[distant nest]

ok, that's what I was asking

[subtle raft]

when you Air Link to the Quest though you no longer have Hand Tracking and I thought that was odd at first, but I get it now, it's because they don't allow you to use hand tracking while linked... because they're Oculus or something

they just turn it off

unless you're running VR Preview through Unreal or Unity

[wicked quarry]

yep i installed that

i can try re-installing it ?

[distant nest]

And you followed this guide meticulously? https://docs.unrealengine.com/4.27/en-US/SharingAndReleasing/Mobile/Android/Setup/AndroidStudio/

[subtle raft]

has anyone got hand tracking to work with OpenXR in 4.27? does it work linked in OpenXR?

[wicked quarry]

yeah i did - although the guide is for android 4.0 which is a bit older

[distant nest]

I'm out of my depth on the mac, but in general for android you should install the exact versions specified.

[wicked quarry]

ahh okay no problem. thanks though !

[idle marten]

Hey everyone, I just updated a VR project to 4.27.. not sure what version it was in previously.. I'm a contractor.. but I'm getting thiiiss..

now it's tellin me to just touch or modify anything in the texture editor to fix it... but theres like.. 300+ files here? sooo.. any way I can do this more efficiently?

[distant nest]

I don't think this has anything to do with VR. Maybe use the bulk edit property matrix.

[idle marten]

I just noticed it's all the same file

but yes I was thinking about that.. but it didn't come up in the drop-down when i rightclicked on them

[wicked quarry]

also managed to solve the earlier issue, but has anyone deployed their VR environment into Quest 2 and it just turns up showing a black screen ?

[flat shoal]

anyone seen different reflections in archviz VR than what's seen in the editor? like, when you press play in VR it doesn't look the same...

[rocky nexus]

vr is not editor

[flat shoal]

so you've seen it? do you know how to compensate for it?

[rocky nexus]

nope, all im saying that you cant assume that what you see in editor will be the same as in vr

[flat shoal]

yeah, well that's obvious from my question so it doesn't really help me 😉

[rocky nexus]

perhaps scalability settings, or material. if thats mobile vr you are testing its entire different rendering stuff there

[mighty carbon]

Has anyone managed to build and run UE5 project on Quest 2 ? (UE5 built from current branch, not EA)

[idle marten]

Hey everyone! is anyone familiar with settings that change a project to being VR or not VR in the quest? what I mean is.. well.. here's a screen shot..

this was supposed to be a VR project when I packaged it.. I'm working as a contractor on some older stuff for a company.. updating it

[distant nest]

You can reproduce this by deploying to android with the OculusVR plugin disabled, or openxr if you're using that.

[idle marten]

I think it ended up being I was missing "package for oculus mobile devices" and then ya know.. adding the quest and quest2 in the drop down

we'll see

a few other settings were also missing

not sure what version this project was previously in but bringing it to 4.27 definitely shook things up a bit lol

@distant nestthank you!

[distant nest]

yeah, sometimes running in that pancake mode can be a useful tool, it lets you see if oculus is breaking certain features

[idle marten]

cool

anyone have any ideas on this? UATHelper: Packaging (Android (ASTC)): ERROR: cmd.exe failed with args /c "D:\AR_BrianL\ARS18042_LTW_Church_VR\Intermediate\Android\armv7\gradle\rungradle.bat" :app:assembleDebug

[marble frost]

Try doing full rebuild, it has worked for me in the past

[idle marten]

in visual studio?

cool

[marble frost]

No, in the packaging settings in UE4

[idle marten]

oh ok

[granite idol]

Alright folks, I need some rubber ducking or some pointers.

1. To see spawned VR widget actor that's in the world though objects. So it's visible even if something is in front of player
2. See hands when in front of widget

I know it has something to do with materials, depth or stencil, but whatever I tried yesterday didn't work. So if anyone has done this in the past and has some pointers, let me know!

[chilly ocean]

Is there a way with software to force the Oculus headset to not go to sleep within Unreal when taking the headset off of your head?

[tired tree]

@chilly ocean tape over the sensor is the easiest

[chilly ocean]

@tired tree Correct. I’ll be more specific and state I am asking for a software solution.

I don’t understand why they can’t take an approach like Steam did and keep the experience running through the headset…

[tired tree]

ah for shipping

there are several active complaints about that very thing on their forums

[distant nest]

as someone who regular tapes over the sensor, and then forgets and comes back to a dead headset 2 hours later, I'd say the defaults make sense for the majority of users. The best software solution right now is instructing users to tape over the sensor if you really need that.

Oculus won't even let us control the strength of the anti-aliasing, doubtful they'd ever let us disable auto-shutoff at the software level 😠. Would love to do both though.

[ornate raptor]

While you're working in the editor, you can toggle a setting in the Oculus Debug Tool. Not sure how well that plays with Link/Air Link, though. Haven't tried it

[tired tree]

yeah that is still not shipping though

[hard mantle]

Does anyone know how to tweak USceneCaptureComponent2d to run a single-pass-instanced stereo capture?

It appears to run with EStereoscopicPass::eSSP_FULL, https://docs.unrealengine.com/4.26/en-US/API/Runtime/Engine/EStereoscopicPass/

which indicates... no stereoscopic rendering

[wheat holly]

Why do you need a scene capture component to do that if I may ask? Correct me if I'm wrong, but to my knowledge the technique is used to, in a lot of cases, optimise VR headsets considering there are 2 'screens'/eyes. A capture component isn't used to render a VR headset view as far as I'm aware of.

In a typical OpenGL stereo rendering, each eye buffer must be rendered in sequence, doubling application and driver overhead. With Single Pass Stereo rendering, objects are rendered once to the left eye buffer, then duplicated to the right buffer automatically with appropriate modifications for vertex position and view-dependent variables such as reflection. It primarily reduces CPU usage, and the GPU performance is unchanged largely. If your application is CPU-bound or draw call bound, we strongly recommend using Single Pass Stereo rendering to improve performance.

[hard mantle]

I'm doing a render-to-texture for in VR and doing two separate renders is extremely expensive when a single-pass-instanced render would be valid

I'm making a portal effect- most people seem to use two scenecapture2ds but it should be doable with one if they use instanced rendering for the pass

[wheat holly]

Ah alright, then I'm not sure. That's a bit outside my knowledge xD

[manic tapir]

packaged version of my game is crashing with this:

Assertion failed: ClearValue.ColorBinding == EClearBinding::EDepthStencilBound

this only happens when vr headset is plugged in

[hard mantle]

Does the assertion say which file it was in? https://github.com/EpicGames/UnrealEngine/search?q=EDepthStencilBound are the candidates

[manic tapir]

d3d11commands line 1150

[hard mantle]

Texture: %s does not have a DS value bound for fast clears

[manic tapir]

what does this mean?

[hard mantle]

no idea; presumably you don't have a depth stencil bound for fast clears, yet you have clearDepth or clearStencil set to true

https://github.com/EpicGames/UnrealEngine/blob/99b6e203a15d04fc7bbbf554c421a985c1ccb8f1/Engine/Source/Runtime/Windows/D3D11RHI/Private/D3D11Commands.cpp#L1150

[manic tapir]

set to true where? This seemingly came out of nowhere.

[hard mantle]

dunno, a debugger might help

[manic tapir]

So this doesn't happen on a shipping build. weird

[hard mantle]

some types of asserts are elided in prod builds; instead, you'll just get unexpected / undefined behaviour

[elfin stirrup]

Has anyone been able to do VR with NvRTX_Caustics Branch? When I previewed it in VR, the reflections and refractions were only rendered on the left side.

[mighty carbon]

RTX only works in deferred renderer

[tribal lintel]

I've found upgrading to windows 11 completely destroys my VR performance. When starting steamVR, everything in the home is fine, when launching any shipped unreal game, I get this terrible frame stuttering that continues even when going back to the home, and restarting steamVR. Restarting my PC fixes it but then it happens again when opening any unreal game. It's not just headset lagging because the entire FPS is below 40. Others are reporting this as well and saying VR support isn't high on the priority list for windows 11 right now. Definitely avoid for now if you are developing for VR. After going back to windows 10, my next restart will force me back to windows 11. If your system is compatible, go into your UEFI settings and disable TPM so your machine is no longer compatible with windows 11. Despite me disabling TPM windows update is still saying my next update will install windows 11. I hope this wasn't an oversight and I will brick my machine if I accidently "restart and update", anyone else gone down this rabbit hole? Win 11 has been out a while idk why it's just now being forced on me

[distant nest]

My win 11 VR performance is identical to win 10

[tribal lintel]

whats your hmd

[distant nest]

Vive business with vive streaming, Quest 2 with oculus streaming

[tribal lintel]

have you tried either with steamVR yet?

[distant nest]

I played boneworks on the Quest 2 for a few hours yesterday via steam

[tribal lintel]

strange, for me it only happens when using steamVR with unreal or an unreal game, thanks maybe I'll try to see whats going on

[distant nest]

I don't use steam home though, maybe it's related to that

[tribal lintel]

every other game and steamVR home is perfectly fine, it's only when running anything using editor vr preview or even playing a steamVR unreal game like pavlov

then it continues until restart

[distant nest]

maybe take a look at your task manager processes tab, sort by GPU, might find a process using GPU that you don't expect

[mighty carbon]

Oculus doesn't support Win 11 yet

[viscid olive]

Hey. I'm having some trouble with replicating rotation of my character Mesh in VR.

In single player, The Mesh rotates based on the HMD rotation. Works great.
In multiplayer, rotation only happens locally. Server or client.
Tried to RPC the Mesh transform to server, then to multicast with no luck.

Anybody have advice or maybe an idea in the right direction? I have EVERYTHING else replicated except rotation. It's annoying me. lol.

[dim imp]

Hey! Is forward rendering still the way to go for VR in 2022?

[reef rune]

Hi all, I'm experimenting with RTXGI and got it to work (after setting r.ForwardShading=False), however in VR the performance is very poor. Is there anyone who has it working smoothly? Using Reverb G2.

[fiery cloud]

Good luck! Even on the most powerful enthusiest gamer desktops will struggle with RTXGI in VR. You'll almost certainly have to use something like FSR or DLSS to get a reasonable framerate for warping, let alone hitting 90 or 120hz

[reef rune]

I'm using DLSS but yeah still quite choppy. Especially warpy visuals around the controllers.

[hollow cosmos]

Has anyone come across a workflow where you could write on a body in VR and get a material for the mesh on its own layer of what you'vr just drawn?

Even better if I can do it on a body with collision and physics but I know that's a whole other level.

[hard mantle]

I've been trying to get deferred rendering to work but - while SteamVR has smooth tracking, something about the OpenXR plugin performs much worse

It is far worse as the framerate drops (fluctuating from 119 to 120 instead of definitively locked at 120 makes it track extremely poorly).

I'm still trying to determine what's going on here, because Unity doesn't exhibit this issue at even worse framerates under deferred rendering

[copper chasm]

Vd does

[wraith sky]

Default VR project has broken Debug View modes, is it possible to fix?

I understand that's probably due to Forward shading.

[jovial violet]

real quick, If im building for steamVR but I want to use my oculus quest 2 headset through steamVR which plugins do I have enabled in ue4? oculusopenxr, openxr, steamVR or oculus VR? bit confused by it all

[wraith sky]

OpenXR

[jovial violet]

so JUST openXR and nothing else?

[wraith sky]

yep

[jovial violet]

Thank you 🙂 I'll give it a shot

[wraith sky]

Basically, OpenXR plugin in UE4 will talk to SteamVR API

[jovial violet]

great

[wraith sky]

Both, Oculus and Steam support OpenXR

@jovial violet

[paper epoch]

is there any android permission to prevent the quest from going to sleep? I am making a multiplayer app and removing thr headset causes it to sleep and disconnect.

[wheat holly]

I believe in the developer application from Oculus for PC you can change it for development purposes, if you want it for regular users I’m not sure.

[paper epoch]

regular purposes for multiplayer. Headset sleep makes it disconnect.

[sour iris]

How do you properly rotate 4.27 VRPawn to a desired rotation? Seems like Teleport and SetActorRotation rotate something else not the VRPawn's camera

I'd like the player to face certain way after pressing a button

[quasi radish]

Trying to launch a project for VR (Oculus Quest 2) for the first time. I did all the android setup and all the setup in the quest; unreal recognizes the device. But when I hit launch, I get the following errors:

ERROR: Unable to find a valid SDK for Android. Must be between r21a and r23a
ERROR: Platform Android is not a valid platform to build. Check that the SDK is installed properly.

Has anyone faced something similar?

I'm not sure where I can see which android sdk version, but I did follow the android studio setup (found in the documentation)

my VR Preview play in editor is also grayed out, probably due to a similar issue (but my pc is recognizing the oculus, when I do the adb devices command it gets listed, and it appears as an option)

[dim imp]

Would love a response to that. thanks 🙂

[paper epoch]

well you could reset hmd rotation and set a world rotation. I did it by modding the teleport in the VR template will have to check the exact code.

[paper epoch]

go to android studio and check what sdks you have. Probably might be missing those

[paper epoch]

If you are trying to use quest 2 on pc you need to turn on oculus link to use it like a rift

[quasi radish]

is android sdk version the same as API level?

[jovial violet]

I'd like to know this too, I'm building specifically for oculus quest 2 and the documentation recommends NDK 21b, SDK ~29 and API 32 but I thought the API was the SDK

I can't really find a straight forward answer on which settings I need android studio to be. Specifically which API, SDK and NDK (which I presume is the one created by the android setup bat file within the engine itself

[rocky nexus]

32 doesnt work without some changes, install 29 and get rid of 32

[quasi radish]

this didn't solve it for me. I event uninstalled android studio, deleted all the AppData android stuff, re-installed everything, uninstalled 32 and installed 29, run SetupAndroid.bat... but nothing

[paper epoch]

no oh wait I think the latest does not work. We build ours on sdk api 21 or 19 (cant recall) to retain quest 1 and 2 compatibility.

It could also be your jdk. It was a pain setting up for me at least. But then again we use 4.26

[quasi radish]

i thought the jdk was installed automatically when you run the SetupAndroid.bat ?

[quasi radish]

same thing. Installed 21

(presuming sdk version == API level)

@paper epoch there is a small glass between the lenses, just tape it (face sensor)

or stick a camera shutter

[paper epoch]

Ummm not something that can be said cuz boss passes around headsets in bulk. 😅 Plus android does have a permission to prevent sleep. I have seen it in some apps.

[paper epoch]

What you install is the max version. In your sdk settings set it to android-21

[quasi radish]

in unreal? I have it android-21

[paper epoch]

Did you check your settings in platforms android

[quasi radish]

yeah. I did all the settings described in this video:

You have to configure your sdk per project. There is a button you press

Ok are you packaging for arm 64?

Arm 7 can have problems

[quasi radish]

do you mean this?

for now I'm not even trying to package. Just trying to launch it, (or even the VR Preview, but it's grayed out)

[paper epoch]

No scroll down a bit

And is this UE5 EA?

[quasi radish]

here?

yeah, it's UE 5

(the support arm64 wasn't on. I turned it on. But still can't launch)

[paper epoch]

Why not package and UE5 is a reaaaaly bad idea considering it’s not stable yet. Also is openxr off? It has been causing trouble for a while

Also turn off Vulkan. Quest does not handle it well at least via UE

[quasi radish]

unfortunately the project I'm working is ue5. Trying to get it running on VR. If I open the project with an earlier editor version, the assets don't load (asset saved with an engine version higher than the current one)

[paper epoch]

Bad idea doing it in ue5. 4.27 is the latest advisable. And you can’t open with older engine

How much did you code in your project?

[quasi radish]

if the ideia is to re-create the project in ue4.27, it's completely impossible at this point 😄

I am however first trying to get the Unreal VR starter project running in the oculus, since i've never done VR before. I'll try that in 4.27 to test it

using the default android studio setup in the documentation

[paper epoch]

yeah I think that is a better idea. I could crosscheck my config at work tomorrow. TBH openxr is a mess and so is their new template esp considering no hand meshes

[distant nest]

Vulkan works great on the quest in UE4, it destroys the performance of opengl. Been using it for the last 2 years.

[distant nest]

Set your minimum and target SDK to 26. Set to use arm64 + vulkan only. Make sure you have quest items specified in advanced apk packaging. Set ndk API laevel to android-26.

Hello everyone, does anyone know how I can get the oculus passthrough to work?
I wish I could do something similar to this.
