I haven't messed around with it too much though

I don't know how that affects SteamVR action manifests and binding

[rare tulip]

OpenXR was already making SteamVR action manifests and bindings funky IIRC?
I'm honestly loving the enhanced input system for VR, works very well as of 5.1, although was still jank in 5.

Hi, is there any plugin to recognize hand tracking gestures just from OpenXR data without vendor specific plugins? I've only found the oculus/vive/ultraleap/hololens plugins but all of them require the specific runtime for that vendor. I want something generic that works with only OpenXR hand tracking data

Hey guys I have an issue on my Vr project. I call a widget to appear after triggering a box, but for some reason it's super zoomed and I can't see the whole widget.

Do you know what is the problem ?

[zinc cipher]

Try increasing draw size in the details panel

[clear gyro]

I mean I did that but, something that I haven't quite understood yet. Does it have to be 3d the UI, in the Vr space and only works that way ?

I am getting this weird lighting corruption when im trying to bake lighting for my VR app. When I actually build to my quest I dont get this corruption but its only in the editor. Is showing up in both the PC rendering and the Vulken preview. Any ideas of what might be causing it?

[slender jackal]

it may just be your light

[last patrol]

How so? Its def like messing up the textures

[slender jackal]

if the light is very bright and bounces lighting is turned off it is very easy to get this effect

[last patrol]

I have num indirect lighting bounces maxed out at 10 though

Pretty new to baking lighting

Anyone else experienced a drop in performance when switching to ue5.1?

[hushed shuttle]

HI how can i boost perf in VR? i'm at 60 fps in normal mode but dropping and having artifacts ingame

[mighty carbon]

https://tenor.com/view/everyone-the-professional-shout-gif-12696023

especially if you used software occlusion culling in 4.27

[zinc cipher]

I was using 5.0 actually

[mighty carbon]

and had great performance?

PC or Quest 2 ?

[zinc cipher]

Pc and well, performance was quite better, 5.1 takes forever to launch the standalone and is overall slower. Also, it keeps compiling shaders for some reason

[mighty carbon]

ah, my bad.. I always think of Quest 2 when UE5.x and performance come into the conversation 😅

[shut bone]

I don't suppose the Epic/Unreal team can ask nicely for (or put some pressure on) Meta to compile the OVRPlugin part of the plugin for Linux/Mac. The actual code they supply compiles (that wraps around ovr & openxr), but they only ship the pre-compiled OVRPlugin (and no source for it) for Windows/Android. If they shipped an Linux/Mac version that would make us developers using Mac/Linux on VR a LOT lot happier. 💗

[calm orbit]

could someone point me to valid resources that will help me setup my oculus **quest 1 **with ue 4.27 .. Im slowly loosing my mind.

Hey guys, Im in need of a bit of help. I'm trying to run a VR location scout of some environments I have in UE5.1 and im getting an immediate crash when I launch VR Editor Mode,

Error line reads :vr mode Assertion failed: IsValid() [File:D:\build++UE5\Sync\Engine\Source\Runtime\Core\Public\Templates\SharedPointer.h] [Line: 1071]

I tested a new project with the VR template and that seemed to work, so not sure if its got something to do with the fact that I started with the Virtual Production Template, but I really need to figure this out and I cant seem to find any solution. Any help would be seriously amazing!

Edit: on starting a new Virtual Production Template, I get the same error. I'm running an Oculus Quest 2, using a Link Cable if it helps

Question: Has anyone successfully launched a “VR Preview” of the UE5.1 VR template using a Vive Cosmos Elite and the OpenXR plugin? Mine crashes on every play.

**Steps to Reproduce: **Create a fresh copy of the UE5.1 VR template with Starter Content. Play default level in VR using VR Preview, with SteamVR and VIVE Console running. Crashes every time.

Error Message Reported: Assertion failed: InOutSizeX != 0 && InOutSizeY != 0 [File:D:\build\++UE5\Sync\Engine\Plugins\Runtime\OpenXR\Source\OpenXRHMD\Private\OpenXRHMD.cpp] [Line: 890]

**Attempted Fixes: ** Things I’ve tried, based on other forum posts:

• Switched targeted RHI from DX12 to DX11 or Vulcan in Project Settings => Platforms => Windows => Default RHI. Result: Same crash as above.

• Switched VR plugin from OpenXR to SteamVR plugin. Result: VR Preview works when using SteamVR plugin, but controller buttons don’t function. (Likely because the deprecated StreamVR plugin doesn’t support the Enhanced Input System.)

[hallow knoll]

There's no Oculus Runtime for Linux/Mac. Doesn't make much sense without that.

[hallow knoll]

I don't have a Cosmos. Are you using the SteamVR runtime with it? Does it work with other OpenXR games? If so, I'd ask on the HTC Forums.

[orchid mortar]

Thanks for the reply Victor. I am using the StreamVR runtime. I'll try finding some OpenRX games to try out. I'll post back here if I learn anything specific from the HTC forums. Hopefully I can find a solution 'cause I've got 18 game dev students up here in Winnipeg, Manitoba, Canada hoping to learn about crafting VR experience using Unreal. 🙂

[hallow knoll]

You might need the Vive OpenXR Plugin: https://developer.vive.com/resources/openxr/openxr-pcvr/download/latest/

[orchid mortar]

Cool. I'll look into this!

[orchid mortar]

Unfortunately I'm getting the same assertion failed error as before with the Vive OpenXR Plugin installed. This goes for both the default UE5.1 VR template and Vive's OpenXR Unreal Sample Project for UE5.1. I'll post to the HTC forums now.

[hushed shuttle]

hi i'm trying to have a 360 video play in headset. I need it to run smoothly so i used BINK but then i can't move my character

[shut bone]

Isn't the OVRPlugin.dll & .so the runtime? The actual rest of the MetaXR plugin compiles fine on Linux (& I assume mac). However the metaxr plugin at the lowest level uses the OVRPlugin.dll/.so So Unless I'm missing something, if they compiled that for Linux/Mac, everything should work on Linux/Mac...

[hallow knoll]

The runtime is the Oculus Software that you install on your machine for headsets to be able to communicate with the computer. That software doesn't have support for Linux/Mac.

[shut bone]

Oh, no, you misunderstand me --- that isn't the piece I'm worried about. I am NOT looking for Desktop VR, I'm looking for pure Quest VR!

The issue (I believe) is that the MetaXR plugin won't work on Linux because the OVRPlugin isn't compiled for Linux. I have no ability to set any MetaXR properties inside Unreal for any "extra" stuff that MetaXR adds to Unreal (when using it under Linux). The funny thing is I can build MetaXR and it even can be compiled into the Android app, but basically can't enable it or access any MetaXR settings to enable/disable (since they don't show because of the lack of OVRPlugin) -- it basically becomes a useless plugin adding nothing to the build (except size) when building the app from Linux/mac.

All I want is a working MetaXR plugin on Linux/Mac so that I can configure pure Oculus VR (no desktop) for the Android app that Unreal generates for it.

Isn't that abstracted away by the online subsystem, and you should not need to call the ovr_ functions?

Hi guysss, I hope everyone is good. I ended up in an issue. I am working in a Vr project and I want the character to open drawers, etc and I am trying a method with a spline and some blueprints.

I just press grab and it goes above me 😅

hey everyone

Expecting to find a type to be declared in a module rules named 'OculusXRHMD' in UE5Rules, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null. This type must derive from the 'ModuleRules' type defined by Unreal Build Tool.

its worked some times

but when i turn on my pc in next day it just STOPPED WORK

how did you get their transforms?

[sonic fjord]

I've been weighing the pros/cons between project migration vs dealing with 4.27, leaning towards project migration so far. difficult to say, honestly.

Hello guys, I am creating an inspect action I a Vr project and I am kinda stuck. Do you know like a good tutorial or any resource to help me?

[limpid widget]

I mean, it has been that way all the time, no? Check the oculus online subsystem

[sonic fjord]

update: this doesn't seem to work. 😦 having the plugin enabled causes package build to error out with no messages/logs on why.
potential solution for vive trackers in 4.27. uses openxr, requires engine source modification and a new plugin.
https://varjo.com/vr-lab/recipe-using-motion-trackers-with-unreal-engine-projects/
not sure if/when I'll be able to test it, but it's worth a look for others who needed them to work on 4.27.

[limpid widget]

yea, I was right. It is not deprecated, instead, Unreal already does it for you.

https://github.com/EpicGames/UnrealEngine/blob/release/Engine/Plugins/Online/OnlineSubsystemOculus/Source/Private/OnlineSubsystemOculus.cpp
Check here, it does all the ovr initialization.

Please read this documentation:
https://docs.unrealengine.com/5.1/en-US/online-subsystem-in-unreal-engine/

Unreal provides an interface called the Online SubSystem, which abstracts all those calls for you and also based on your platform.
It requires you to set the Online Subsystem to whatever you need within your Engine.ini (so in your case, the oculus one).

And then you can call the interfaces, which should get you your user account ID.

so....no one has problems with anti-aliasing?? i still haven't found a solution to build an .apk for quest with MSAA activated. This is for a job, not hobby i only have one more week to fix this, please if anyone has any hints or help i would really appreciate it, tried other tips nut none work for me

[rocky nexus]

if you have forward rendered and msaa enabled and its not working, you will have a bad time. did you test in a fresh project with basics setup or something like that

My problems come from this as well. Enabling MSAA turned one eye black, which "Mobile Multi-View" was supposed to fix, but I can't even package the game with that option enabled.

[analog echo]

Hi guys! Im a UE newbie that needs some guidance! Im trying to make a VR experience on the Quest Pro that is as photorealistic as possible, so I naturally want to use UE5 and leverage the Nanite / Lumen / Metahuman features.
This experience would also have object interactivity, preferably using hands instead of controllers.
Does anyone have recommendations for laptops I should be using for this specific use case? I thought my Macbook Pro would work, but I tried connecting my Quest Pro and saw that I needed to download the Quest desktop app, which requires an M1 chip and my macbook doesnt have that.
I dont mind buying a new laptop for this specific use case, and would love to hear recs on what I should get!
Also, has anyone built a super realistic experience using UE5 and the Quest Pro? I feel like I havent seen that combo a lot in my research. Would love to connect with those that have built this before!

Thanks in advance!

[sonic fjord]

lumen/nanite require more graphics compute capability than is offered in mobile devices like the quest 2/pro/3.

[jade kettle]

Right off the bat, VR with Nanite and Lumen doesn't work (yet)

[sonic fjord]

you may have to stick to pre-built lighting for now to get the maximum realism and lighting detail.

And on a 4090. Also performance and results have been rather inconsistent

[steel badger]

Yes tried with 5.1 and 4.27 using the vr template, even searched for a tutorial on how to configure for 4.27 and was not able to have anti-aliasing and with bad framerate. I'm thinking the game is auto scaling the graphics and settings anti aliasing off. But it's super weird cause if I'm Not mistaken the oculus home is done in unreal engine and has anti-aliasing

wired

[fiery gale]

If you are using Steam VR there is a resolution setting there somewhere.

[earnest willow]

right in the headset but it doesn't change much

[fiery gale]

I had the same problem, but then I swapped to a USB C to C cable and it was fine. At least I think that's what fixed it.

I'm always changing stuff lol. I also switched away from the SteamVR app to Pico's own.

And I'm always changing stuff around in the Unreal settings.

How to develop a simple vr multiplayer game in unreal 5.1

it's better NOT to develop multiplayer game being a beginner at all, VR or not

make a simple small single-player game first

[clear gyro]

Hello there! I want to create a mechanism where the player can inspect an object like in for example resident evil, where you can rotate the object or if its a letter for example the text will appear in a ui near the letter and stuff like that. I followed this tutorial --> https://www.youtube.com/watch?v=aR7PVYo2ZGo&ab_channel=MattAspland and I tried to adjust the blueprint for vr use but to no avail.

I want to integrate those 2 techniques in my game but I can't. I understand that those are 2 different kinds of blueprints but I want to learn how to create that kind of iteration.

Thank you beforehand!

[hushed shuttle]

What anti alisaing method do you recommend for Vr using Forward rendering with desktop ? rhanks

[hushed shuttle]

Check the aaxis inputs in the project settings and see if they are related to something

[hallow knoll]

MSAA

[hushed shuttle]

any idea why i would get such an grainy image with MSAA ? thanks a lot. I just have a Skysphere with custom cubemap

[sturdy coral]

after you load into your game run r.antialiasingmethod? on the console to see if it has been changed by something outside of project settings

I just tried and stat gpu shows TAA for me too even when I switch to FXAA though, but I can see the time go down a lot

[sturdy coral]

that image is all from a cubemap? the black specs look kind of like artifacts you see with tracing inside a shader if the depth prepass doesn't exactly match the main pass depth (like with POM at steep angles)

[hushed shuttle]

no sorry it''s just the light that's from a cube map

this is a classic mesh

tsr and other AA is working perfect

[sturdy coral]

what does it look like in unlit MSAA?

TSR and other TAA will hide single pixel noise a lot of times

[hushed shuttle]

ahha like this wow

[hushed shuttle]

yes that's maybe what's hapeingn since the unlit is returning only a color

really annoying because tsr is so crispy haha but so expensive right

[sturdy coral]

how about wireframe view?

[hushed shuttle]

by the way i have no idea why the one in the back is purple

Unreal is infinite

[sturdy coral]

yeah, it is definitely a full mesh with no kind of tracing going on in the shader it looks like, I'm not sure what could cause it

I did some raytraced spheres and stuff for something and saw black speckling like that and the solution was to make sure anything that output to depth was wrapped in precise() so that it would calculate the exact same way between passes

[hushed shuttle]

there are exact same mesh duplicated if that can help

can it be becuse i have 3 same materials ?

i wanted to delete them but i need to go the actual mesh

[sturdy coral]

when moving disoccluded parts of the screen may get full weight for the frame so the speckling stuff may show through even with taa

do you see it if you switch them all to something like default material?

if not, check if that stomach material has anything hooked to pixel depth offset

[hushed shuttle]

it seems better but not really clear

thank you so much

no its pretty basic

[sturdy coral]

I don't see the dark black pixels there

[hushed shuttle]

but isn't it because of the material ?

[sturdy coral]

in your screenshot you left the material unchanged on the front though, before it was lots of super dark black spots

the general noisiness will always be there without TAA I think because SSAO and SSR and stuff works stochastically (assuming that's what is causing it)

you can try turning both of those off if they are on

[hushed shuttle]

i'll make a video so it's more clear

[hushed shuttle]

ah great where could i do that ? i have no PPV btw

"stochastically " nice word 🙂

[sturdy coral]

I don't see any of these kind of black pixels in your second image:

[hushed shuttle]

yeah it's weird maybe the black pixels where caused by the overlap of same materials

[sturdy coral]

just means they shoot out rays kind of randomly in a noisy way, and with TAA they can smooth out the noise over multiple frames

[hushed shuttle]

oh wow ok amazing

and you see the "sky" has also weird artifacts

[sturdy coral]

the sky stuff kind of looks like lumen's noise

[hushed shuttle]

yeah no black pixels are still here

[hushed shuttle]

ill try the lumen visualisation

if ti can help

1.looking at the sky
2. looking at the grounnd

i disabled ssr with this command, : r.ssr 1 didn't do much

[sturdy coral]

There are probably some settings on the skybox to make it not receive any lumen light, I know there is stuff to have it render last and it should probably be fully unlit emissive

if you are doing full lumen and stuff the other noise could be from that and not SSAO/SSR, and I don't think most AA other than TSR and maybe plain TAA is expected to work with lumen

[hushed shuttle]

i see... What do you mean full lumen ?

[sturdy coral]

just lumen

one part of lumen is SSGI too which might have some of that fine grained noisiness

[hushed shuttle]

here is the mat of the sphere suurrounding the scene

i dont necesarily want to have lumen since i don't use directional light and few moving lights but i need to be in forward rendering to use VR with desktop

[sturdy coral]

I'm not sure what is going on with that, I didn't think unlit would do anything like that even with lumen on

[hushed shuttle]

yeah i removed it and the issue is still here

i'll send you the skybox details

you mean cube map?

[hushed shuttle]

ah so what should i use for a classic VR project ?

actulally find some sort of a solution by removing the skybox and adding a directional light

i unchecked the "cast shadow" but i'm still getting shadows where could they be coming from

[sturdy coral]

possibly screenspace shadows

you will expect parts to be dark if the normals are fully facing away from the sun too even without shadows, but it does look some stuff is casting them

[hushed shuttle]

hmm i see

[hushed shuttle]

ill try and disable them thanks

cause i want an even light everywhere

Hey guys
I make oculus app with hands tracking only
Maybe someone know... Is it possible to make custom notification BEFORE app starts? Smth like "put down the controllers and use hands" with ok button below

[rocky nexus]

if you select hand tracking as only supported method it would probably pop up

[glad cliff]

Thank you, for the first try it does not work for me, but I change "Auto switch between hands and controllers" = false and now it's pop up

[dapper token]

Hello! Is there a way of getting motion controller velocity without setting it's location every tick?

[hard wraith]

I am using the UE5.1.1 VR template with my Oculus Quest 2, and the controller has stopped tracking. I have tried verifying and reinstalling SteamVR, as well as restarting my Oculus and Unreal project multiple times, but nothing seems to work. I was able to get it to work on another UE5.1.1 VR template project. However, when I imported the original starter content pawn to the broken project, it also seemed to be broken. Is there a way to fix this?

[reef sierra]

Hello, I wanna add a damage indicator to the player similar to call of duty where the screen starts pulsing red, all the tutorials show it on tp or fp but none for Vr and I’m sure u guys know that widgets don’t work for vr so idk what to do and I’m stuck with a deadline coming up.
(I tried post process material and it didn’t work)

[hard wraith]

you could try to add a plane thats in front of your vr camera that has the blood effect on it

[lapis fractal]

My quest 2 on default VR template in UE5.1.1 is just works. It's nothing related with SteamVR. It use OpenXR runtime. Make sure enable it in oculus desktop app.

[hard wraith]

setting openxr runtime to oculus doesn't work and it has broken twice now on two different projects

i can make a new project and it will work but it will stop working randomly as what happened to two project now

[lapis fractal]

At least you could add your new project to the local source control (like git). That helps to tracking which part of asset or codes you just modified. If just broken randomly, I think may be you should focus on openxr runtime issue.

[hard wraith]

I restarted my Steam, Oculus app, headset, computer, and verified SteamVR. Oculus and Steam both say I have controllers connected and they work in other games. However, they are not working in my Unreal Engine project. I edited the base VR Pawn, so I re-added the original VR Pawn to see if it was my code causing the issue. However, it still didn't work.

I also changed my OpenXR runtime to SteamVR and Oculus, but it didn't make any difference.

[worldly peak]

Can the Upper Body IK plugin be replicated. When I try to use it the whole mesh disappears on all other clients. The replication works with my own custom IK solution which is similar to the plugin but just the basics so I know the values do replicate correctly

[fluid sky]

Did you have to install Android Studio etc first?

[zinc cipher]

How do you keep ui (spawned as actors) from changing colors based on light? Once I added a day/night cycle the colors of my uis keep changing

[sturdy coral]

there is a material node somewhere that lets you set a constant exposure adjusted brightness

they mention it in the gdc talk on integrating lumen with fortnite, that they use it for the glowy effects around chests and stuff so they are the same screen brightness whether indoors or outdoors

[zinc cipher]

Could disabling auto exposure (eye adaptation) be it?

[sturdy coral]

it might be this node , though I don't know if that covers manual exposure changes

disabling exposure changes could keep the UI the same, but between day and night that probably isn't feasible; I'm assuming you are doing something like an unlit material

[zinc cipher]

Yes, unlit shading

I thought that’s the standard way of doing a health/mana bar screen in vr?

[winged gorge]

Hello, when I build my project it won't launch in VR even tho start in vr is enabled

[sturdy coral]

Yeah, it is the standard way. That or overlays (with them you can avoid adjusting the brightness with exposure, and they should be clearer)

[sturdy coral]

Check the logs to see if it tries to load a vr plugin

Then Unreal Engine 4.27 supports Magic Leap2?

[vital oak]

There are no Axis Mappings. Should there be? 😬

actually it started working out of nowhere, did not change anything 😄

[hollow narwhal]

My game keeps crashing on launch on the Oculus Quest 2. I started trying to build empty scenes, but nothing works.

The reason of the crash seems to be this:

05-02 17:53:55.121 10992 11084 D UE      : A texture was marked as a shading rate source but attachment VRS is not supported on this device. Ensure GRHISupportsAttachmentVariableRateShading and GRHIAttachmentVariableRateShadingEnabled are true before specifying a shading rate attachment.```
But I have no idea where it's coming from.

[jade kettle]

So how the hell did this guy get Nanite and Lumen to run stable on VR https://www.youtube.com/watch?v=G7xzlBv8r64

Oh, @left cedar is on Unreal Slackers too lol

[chilly ocean]

I'm curious too... lmk what he says. 5.2 preview can't package so I have to attempt it in 5.1. Will let you know if I get success with lumen in my environment in VR in a packaged build

[jade kettle]

I tried the demo and... it actually works! At least, I can confirm that lumen works because I can see its typical artifacting when shooting the gun. It's hard to tell if Nanite is working without the debug view

Regardless, it's a lot smoother and stable than my attempts with Lumen and/or Nanite

[shadow radish]

@hallow knoll not sure if you might be able to possibly help us.

We are using oculus branch of ue 4.27 and have openxr and steamvr plugin both enabled.

We shipped an update to our build on steam and the controller bindings are recognized on our index when we play on SteamVR with oculus set as the default "Current OpenXR Runtime" for SteamVR but when we set the default OpenXR runtime to SteamVR, it does not recognize our controller bindings for the knuckles.

Do we need to disable the SteamVR Plugin?

[ember forum]

@hallow knoll is there any way to use Distance based LOD's instead of ScreenPercentage. For VR its such a nightmare because every headset has a different resolution and therefore its extremely hard to level the playing field based on screenpercentage, whereas distance based would solve this in a much better way
consider this
the quest2 has higher resolution than a PCVR Index
obviously you can use android to override the screen percentage and get around this, but thats just a simple example, theres different mobile vr headsets with different resolutions as well
for example pico has higher resolution than quest, so now the screen percentage logic won't work to switch as fast on that headset

and then if i have a CV1 Rift, lods will switch faster than someone playing on a pimax for example

which really doesnt make sense, for praticality

[sturdy coral]

you can adjust this

[sturdy coral]

adjust for each platform, depending on how weak it is at processing verts; there is also some built in gpu benchmarking stuff on desktop for setting scalability stuff like that

[graceful turtle]

https://www.youtube.com/watch?v=2gH80dJdXfc

[ember forum]

its not a platform thing

lol

its a headset thing

think about it

PCVR = Vive/Index/Quest2 link/REverb/+ 100 other headsets

thats all Platform = Windows

they all have different resolutions

or are you suggesting that one could get the resolution of the headset per platform then set that value (that might actually work.. 🤔 )

its still incredibly hard to tune this for every headset without actually having those headsets, but its a start i guess.. just a system that clearly wasn't made with VR in mind

[sturdy coral]

Yes

Should have said device not platform

There is a per device override system for phones at least

[sturdy coral]

for desktop, steamvr already chooses a resolution based on a benchmark, so you may be best tuning LODs to the vert perf that works well with that resolution and it should mostly work across cards; I'm assuming oculus on desktop and others probably do that too or if not users adjust their resolution thing to work well with most stuff on their card; final panel resolution of the HMD doesn't matter, the game doesn't actually see that, it only sees the input resolution to the compositor

I'm not 100% the LOD system even takes resolution into account, in the past they had something hardcoded to 1080p for it I think, I don't see that now, but it does use projection matrix to change lods when you do things like zoom in with a scope

a long time ago LODs used to pop a lot when turning your head in VR, I think because they calculated the screen size more accurately depending on where in the FOV it was (at the edge of the screen something the same distance away takes up a lot more pixels in perspective projection, with large FOVs), but I think now they just treat every object as if it as at the center of the screen when calculating its screen radius. I don't see resolution itself entering in in the places I looked but it might be slipping through in a scale factor or something somewhere; there is one you can set separately for scene captures aside from the global r.StaticMeshLODDistanceScale (USceneCapture::LODDistanceFactor)

[sturdy coral]

@ember forum from what I can see with LOD coloration turned on, resolution has no effect on LOD. I think it's only FOV that affects it

[ivory juniper]

Starting very recently, our Development builds only (Shipping is fine) are crashing with UE 5.0.3 - I believe this is due to the Oculus Update. Testing with Quest 2. Anyone have any intel on the matter?

[jade kettle]

Are you using the Oculus branch?

[hollow narwhal]

Oh my! I didn't realize this was my problem as well. I couldn't get my builds to run, but on shipping configuration it worked. Thanks a bunch!

[ivory juniper]

You mean Oculus repo? I'm fairy certain this was just a source build from one of Unreal repo's tagged releases.

[jade kettle]

Right

Ohh, is it crashing on packaging or when launching on the Quest?

[ivory juniper]

Launching in the quest, immediately. And this is with older apks that were working totally fine months ago too, that's why I know it's OS related.

any solution?

[rocky nexus]

just refactored my pause handling to not use built in stuff as i found it pausing way too many things…

[sturdy coral]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Utilities/SetTickablewhenPaused/

Add that on any components involved, you may need some stuff on the UI elements too

[reef sierra]

my pointer isnt a component

[sturdy coral]

What is it? UI element? Are you using a widget interaction component?

[reef sierra]

no its a niagra system beam that spawns when i press B

[sturdy coral]

Niagara systems are scene components

Anything that can attach to an actor in the hierarchy derives from scene component underneath

Or there at least is a top level UNiagaraComponent

There might be extra stuff needed for the niagara timeline to not be based on gametime, but #niagara can probably help better

Hello,
I submitted my game for the Steam review and after reviewing my project they replied Windows Mixed Reality controllers are not working, although I added the Mixed Reality buttons into the input config, I don't have access to any Mixed Reality devices and today I found there's a plugin for Microsoft Windows Mixed Reality and I enabled that, Is there any other solution that I can add before submitting for another review?

[coral swallow]

Are you using all the seperate plugins, like Oculus VR, Steam VR and Windows MR or just using the OpenXR plugin

[stable shadow]

@coral swallow When I use OpenXR my project is not working properly with the Pico 4, Currently these are active plugins: SteamVR, OculusVR and recently Windows Mixed Reality

[coral swallow]

Not too sure about Pico4 or WMR really but I know that SteamVR and OculusVR plugins are deprecated in the latest versions of unreal so youd be best off using OpenXR. If there is an additional plugin for the Pico it should get used before going to OpenXR as far as i know

[cunning tangle]

Hi everyone, I'm new from unity and try to setup unreal engine and I'm not sure about one step : some video said that I should download Android studio in a specific version but the version they said is all different and the latest video who talk about it is in 2022 so my guess is that its probably changed since then. Does anyone have a recommended version I should take?

[coral swallow]

I have 2022.1.1 and i set that up fairly recently but i havent really been using it so it may not work anymore. Though i don't think the version really matters aslong as you have the correct modules included. Way easier than before atleast

I have a weird problem, I created a custom value for the hand model pitch to add to the hand model to make the hand location correct for different controller models and everything works in running as a standalone, but as soon as I package the project the Pico4 controller is not correct and I have to use VIVE's pitch value on the Pico4 to make it work!
It seems in the packaged project steam vr uses a different profile for Pico4 controller tracking!
VIVE, Index, and Quest2 controller working as a standalone and packaged project.

Hey all, the teleport from the VR template (4.27) fails pretty often for me, even when the visualizer is still showing up. Is there any well regarded alternative method? I assume it's because of messy nav data, so not sure if I can just increase the tolerance for that instead

[trail shale]

Getting day-breaking crashes - I had to replace my entire system and reinstall everything - project is 4.26 - I know this is related somehow to Steam VR - I've checked my controller bindings and done the regen action manifest thing - also made sure the json file is pointing to the correct action manifest - and my input stuff doesn't seem to have the binding that causes the crashes (it was some grip thing but I can't remember exactly it) - I can't do anything at all until I figure this out -

Open XR is NOT enabled, I know that can cause an issue with older steam vr

[trail shale]

In my case, it's the Right Trigger that is doing it - and the crash occurs BEFORE the break on the input event is fired

[trail shale]

if anyone comes after me, you have to find the offending entry in your input and remove it - in my case both the right trigger touch and right trigger touch capacitive (an axis event) was causing the crash

Hi guys, I am having an issue where previously fine APK files are no longer running on Quest 2. This is since the last update. They open fro a split second and then crash.
I know @ivory juniper had this issue but has since disappeared so I don't know if he found a solution.
Any help would be amazing as I essentially have a finished project for a client that will no longer run.

[chilly ocean]

Yes, I have. My experience on Valve Index (SteamVR headsets) works with it, but is janky from controller detection. Oculus works pretty well, both using OpenXR. However, I do have to change the pixel density to be about half (0.6) in order to get performance to be well without sacrificing too much resolution

With scenes that use Nanite and Lumen

[ivory juniper]

Hey Dave, I wasn't getting any traction with it - someone suggested to me I needed to port to OpenXR from the Oculus Plugin, which I'm neither confident about (or committed to doing if that is the case), so I've tabled this for now.

Hi, how to simply change the hands in the default 5.1 VR template ? I'd like to have hands not the gloves provided...

[zinc plover]

Hi everyone, so, i've been working on a VR project for some time, its a gallery that you can walk around, has some levels and you can try on some clothing on yourself, etc. Im using a VRF plugin, with inverse kinematics for your body and legs. All good. Untill i tried to add Multiplayer functionality. I tryed at first multiplayer, with 2 computers, running the app from the editor, and it does not work, then i packaged the project, and tryed again. Now it works, but i have the following strange issue:
As the host, i can move and play around normaly, create a session with the node, and all good.
Now i go to the second computer, find the session and join, i can see the host (So far, so good), move around and all is good.
Now, the problem is, when i get back to the host, i have no controllers any more. My hands appear on the ground, and i cant do anything.
I read around the internet for it, and it seems to be a fairle common problem while doing VR multiplayer, and i even found a solution, that has to do with possessing the player before spawning, and possesing the controllers too, the thing is, i have no idea how to do this hahah

by any chance anyone has had the same issue, and can point me in the right direction?
Another thing that i forgot to mention, as i can see the other player moving, his hands do not move, and are just glued to the character's head, but from the second player point of view, my hands work normally. (so, its like the controllers are not replicating, and i dont know how to implement that eigher xD)

[sturdy coral]

This might have changed over time, I think they put some workaround in for it, but set the motion controller player index to -1 by default, and only change it to 0 on the player after it is determined to be locally controlled

I'm not sure if that is your issue or not, usually I think it would cause your hands to move a remote player's

hmm, i read about that too at some point, but it doesnt appear to be my issue, my hands just die. Still i would like to give it a try, how would i have to go about it? where can i find the motion contrller player index to change it to -1? sorry for my noobines hhah

video 2

oh god sorry for the obs screen on the second video

tell me if you understand from there what is happening

lol i mistaked the channel, but still i think its alright, if it serves for clarification and some charitable and smart soul has some insight into what could be the problem xD

[worldly peak]

When Im not in the play mode I get about 110 fps but as soon as I play it in VR the performance drops to 20-24fps. Even in new map which has nothing but few cubes the fps drops just as much. I tried packaging it with development and shipping modes but the issue still remains

Using UE 5.1. Do others have the same issue or is it just me

I can easily run Half Life Alyx and other vr games with 90-120fps so I know the problem is not with my PC specs

[noble stump]

how do i make a widget intractable interact with static mesh

[sturdy coral]

you have to modify it, I made a subclass of static mesh and added to interaction component trace params:

FCollisionQueryParams Params(SCENE_QUERY_STAT(WidgetInteractionComponentTrace));
+                       Params.bReturnFaceIndex = true;```

and get the UV of the hit with (requires a project setting because it uses more memory):

```cpp
bool bUVResult = UGameplayStatics::FindCollisionUV(TraceResult.HitResult, 0, TraceResult.LocalHitLocation);```

and then convert that from uv space to widget coords
```cpp
TraceResult.LocalHitLocation *= HiddenWidgetComponent->GetDrawSize();```

"Support UV From Hit Results" is the physics setting you need to enable on the project

you have to modify a bit more stuff than that, to have the widget interaction component look for meshes of the subclass

Did you happen to ever figure this out? I'm just starting out on VR development in Unreal 5.2 and hitting this same issue with the Reverb G2.

[burnt folio]

I can't seem to get further than World Tick > Self when trying to profile it

[radiant sundial]

No, i ultimately downgraded back to 4.27 tbh. Didnt have nearly as many performance issues as i had with ue5 for vr.

[burnt folio]

Ah, dang that's a shame. Thanks for getting back to me.

[hollow apex]

Anyone got any suggestions on the OpenXR plugin and the Quest 2? I enable the VR editing but controller inputs don't work.

I'm trying in 5.2

[cursive wigeon]

Hi, has anyone encountered/solved the issue of Stereo Layer components w/ Supports Depth enabled rendering a black quad on Quest 2 Vulkan? Thanks! (UE 4.27/Oculus Fork)

[burnt folio]

So far I've narrowed it down to this code block:

// @todo vreditor: In the VREditor, this isn't actually wrapping the whole frame. That would have to happen in EditorEngine.cpp's Tick. However, it didn't seem to affect anything when I tried that.
if (GEngine->XRSystem.IsValid())
{
GEngine->XRSystem->OnStartGameFrame( GEngine->GetWorldContextFromWorldChecked( this ) );
}

[sage gulch]

do emissive material lights work in forward shading?

[hollow narwhal]

Hello, does anyone know if Oculus Hand tracking work on 5.2? I couldn't get it running on 5.1, but I know that 5.0 does work.

[burnt folio]

@radiant sundial just some progress.
So far tracked it down to here:

// TODO: We could do this earlier in the pipeline and allow simulation to run one frame ahead of the render thread.
// That would allow us to take more advantage of Late Update and give projects more headroom for simulation.
// However currently blocking in earlier callbacks can result in a pipeline stall, so we do it here instead.
OnBeginSimulation_GameThread();

[coral swallow]

anyone got a way figured out for camera pushback when trying to stand with something blocking the way? I have a rough idea with a sphere trace above my capsule collider to detect it my resize will clip with the object and block that but i cant get the camera root offsets and such right...

[hidden crest]

Does anyone know how to set or ignore "VR Focus State"?
I'm seeing a new behavior in 5.2 (OpenXR Plugin enabled, HTC VIVE) where controllers don't track until VR Focus State=True.
This is annoying for developing when you are testing inputs and don't want or need to constantly wear the HMD just to test a button press.
It seems covering/uncovering the proximity sensor triggers VR Focus State. I haven't found any info for setting this in Unreal or SteamVR.

RESOLVED: For those having the same issue this fixed it for me: https://forums.unrealengine.com/t/unreal-engine-5-10-enhance-input-doesnt-work-with-htc-vive-controllers/732620/18?u=thejturner

[shadow nimbus]

Hi, how does the "VR mode auto-entry" setting work? I'm trying to enter VR by pressing the UE (5.2) play button, but nothing ever shows up in VR, and I just spawn at the default location with nothing happening, even with the default VR sample test project.
I tried with Virtual Desktop, Air Link, wired, with SteamVR running, SteamVR off, it never works.
Can it work via Virtual Desktop? Does SteamVR has to be running? Is there a specific order in which I must start things?
I enabled the setting as you can see here

[sage gulch]

that's to use the hmd sensor to enter vr, you need to choose vr preview if you want to launch via mouse

[shadow nimbus]

Alright, managed to get that working with Air Link. The view is shaky but at least it shows up in VR now. Thanks!

[rain hemlock]

Hi, to use a wireless headset with Unreal do we mendatory have to use software such as Air Link, Virtual Desktop, ALVR?

[silk lodge]

Figure this out yet? I have done this a bunch of times, and I can send you a sample project. It's complicated

[coral swallow]

If you’re using air link and the view is weird it might be due to the steam vr plugin which has issues when working with oculus. It’s best to just use the OpenXR plugin and disable any of the standalone platform plugins

[gleaming oriole]

does the meta xr plugin come with matchmaking?

[hoary inlet]

matchmaking?

[gleaming oriole]

multiplayer

[burnt folio]

@radiant sundial
Figured I would update, just let me know if you don't want to be tagged

The problem seems to be that when Garbage Collector runs, it throws off the xrWaitFrame function somehow, causing it to wait much longer for all frames following it. The effect can revert back to normal, but it can also get even worse on the next garbage collection if it hasn't fixed itself before that happens. It then gets to the point where xrWaitFrame is waiting even longer than the frame time.

Trying to see if I can figure out a fix for it.

[radiant sundial]

no, i'm fine being pinged. it's useful knowledge and you've done a more in depth review of what's going on then i did at the time. I just probably won't respond to the pings.

[burnt folio]

cool, I'll keep you updated if I find a solution

[radiant sundial]

thanks

[hoary inlet]

no, sorry the Meta XR plugin is for the actual XR stuff (VR , Audio control, AR-passthrough)
If you need match-making, you would implement it through a normal non-vr library as that side of things works completely independent of what is displayed onscreen

[coral swallow]

anyone got a way to get the forward vector and right vector from the camera for use in adding player movement but have it not get affected when looking up or down / tilting your head. I tried negating the corresponding rotation from the vector but it has issues when facing backwards and with certain tilts

[radiant sundial]

right vector = normalize(cross(camfwrd, globalupvector)); fwrd vector= cross(globalupvector, right vector);
(might need to swap the parameters around).

[hardy glacier]

Does anyone know why this flickering coming in GI shadow ?

[burnt folio]

@radiant sundial So, I found that if I measure the time xrWaitFrame takes and it is over a threshold (I set mine to 2ms), and I make it immediately return on the next pass, it fixes the issue. Though obviously not fully ideal since every time GC is run you will get a 1 frame skip. If you have GC running once per minute, you'll notice the skip every minute. I combined this with extending the "Time Between Purging Pending Kill Objects" setting to 10 minutes and now don't really have any issues. Just that once every 10 minutes you may or may not notice a frame skip. Would be better if instead of skipping it was able to sync the timings up another way, but still need to figure that out. Runs great now though...

this is from editing the Unreal Engine 5.2 code

[gleaming oriole]

okay, thanks for the info!

[shadow radish]

Hi UE4 vr devs, we have an issue we are trying to get to the bottom of which we are not fully understanding.

We are packaging our project and have an issue of really poor tracking performance and jitteriness when playing on steamVR with the SteamVR openXR runtime.

We have tried both the unreal 4.27 oculus branch and unreal plus branch of 4.27.

When we play on SteamVR with the oculus openXR runtime, we get perfect performance and the game runs as smooth as butter.

Has anyone run into a similar issue?

We are driving ourselves a bit crazy with it, trying to use different combinations of VR plugins.

[burnt folio]

is it hmd tracking you mean? like it feels like your view is lagging behind your head movement?

[shadow radish]

@burnt folio the hmd somewhat but mostly the hands. Our game is a climbing game and arm swing running game so it seems very noticeable during climbing that it's jittery when running with SteamVR runtime.

[burnt folio]

ah ok, I hadn't really noticed the hands, but I found that if using OpenXR Toolkit with unreal engine 5.2, I have an issue with the HMD view lagging behind my head movement. I then noticed this effect return when I was trying various synchronization strategies in the FOpenXRHMD::OnBeginRendering_GameThread() function so I was wondering if it was a frame timing issue related to what I was working on fixing. Not sure about the controllers though.

[sturdy coral]

use dot product to find how much down/up the player is looking, then lerp from using forward vector (forward from headset) to instead using up vector (top of head) when looking down, down vector (through chin) when looking up

project it down to plane and normalize to get the orientation for walking movement, for flying or swimming you might want to just use pure forward vector of the hmd

[alpine arrow]

hey guys, does anybody have any idea how to make volumetric fog to work in instanced stereo in VR? It seems like it's been an unresolved issue for a long time, and I was just wondering if anybody found a way around this bug.

[sturdy coral]

which engine version? I fixed it here: https://github.com/EpicGames/UnrealEngine/pull/7114

and it got merged a long time ago

[alpine arrow]

I am on UE 5.2, but it didnt work in UE5.1 either

does this only work for source build UE?

[sturdy coral]

it is working for me in 5.1, I've just merged to 5.2 but haven't tested VR yet. what specifically is happening?

I think what I fixed was it used to get drawn in left eye twice and not in right eye

it shouldn't require a source build

[alpine arrow]

Well, i'm trying to follow along with this demo https://www.youtube.com/watch?v=Xd7-rTzfmCo&list=WL&index=3&t=1226s but it doesnt seem to render for both eyes

someone told me to go to settings > Engine > Rendering > separate translucency but it doesn't seem to work

[sturdy coral]

I'm not using the same lighting setup so there might still be issues with a dynamic sun like that or something, I'm mostly all static + some dynamic rect lights; I've tested with dynamic shadowed spotlights and stuff and they worked but I don't think I ever tried directional

[alpine arrow]

i think the lighting is working well, it's just something to do with material's translucent mode that messes with the instanced stereo rendering

i'm still new to ue so i'm not certain

[sturdy coral]

I mostly only use a global fog density lit from the baked volumetric lightgrid and don't have many placed things putting out fog in localized areas, but I have one:

is that what you are using for the settings?

[alpine arrow]

hang on i'll double check

[sturdy coral]

on the gear click on 'show modified properties only'

[alpine arrow]

yup it's modified like that

[sturdy coral]

that should be right

[alpine arrow]

i don't know if it this is important, but I made a material instance... could that be a problem?

[sturdy coral]

do you see the general fog in both eyes and just not the placed particles?

I don't think an instance would be the problem, but I'm not sure

[alpine arrow]

I dont know how to go to stereo view mode, but to visualize it, it looks like this

[alpine arrow]

i see exponential height fog properly, if that's what you mean

[sturdy coral]

which one is it supposed to look like, if you had instanced stereo off and both were working right?

[alpine arrow]

oh, i meant one is the left eye, the other is the right

[sturdy coral]

yeah, when volumetric is on, exponential height fog has like global density settings that are as if you had a big particle everywhere within the max distance

[burnt folio]

ive noticed the same thing with instanced stereo for all translucency, especially water. The effects show up in the left eye but not the right eye. I have noticed that if I angle my headset in a way that the body of water is far to the left of my vision, the effects suddenly work in the right eye

at the moment, i just have instanced stereo turned off

[sturdy coral]

oh ok, that seems like a different problem

[alpine arrow]

I switched off instanced stereo, but it's taking some time to recompile

[sturdy coral]

I've heard of people having that with water but I haven't tried it

[burnt folio]

also rain and splash effects

[sturdy coral]

water is different than normal translucency and has its own extra depth pass I think (to avoid sorting issues looking through waves)

[alpine arrow]

I did some googling, at seems like a prominent problem for translucent materials

[sturdy coral]

it might be a niagara specific problem, I notice mine is using cascade

[alpine arrow]

oh do cascade fog effects work properly in vr?

[sturdy coral]

that's the only difference I see, you could try that and see

and if it is applying to all translucent particles it might be a bigger issue with niagara

[wheat wyvern]

hi, I used to have a stationary sun in 4.27 for main directionnal light (sun) and had no problem with movable objects (obviously VR hands are movable objects). Now in 5.2, hands are lighted with stationary sun and not shadowed when in penumbra. Any idea of the thing I could have missed ?

[alpine arrow]

May I ask what this issue was specifically? was it the old particle system or niagara?

[sturdy coral]

narrow it down though and make sure with volumetric fog on and some global density on the fog actor it works the same on both eyes with instanced stereo, then figure out the particle thing after you are sure that is working

[sturdy coral]

I can't fully remember but I think it was just that particles were drawn twice into the left eye and never into the right eye

in the diff there is this comment I made:

[alpine arrow]

ah, i was just reading thisXD

[sturdy coral]

I never found the actual bug, and instead just turned off instanced stereo for fog particles (and justified it as in that comment, because it is already instancing many slices for each eye in little split up batches)

[alpine arrow]

so, if i understood you correctly, I have to make a tradeoff for either the instanced stereo or fog?

I just checked confirmed it works well with instanced stereo off

[sturdy coral]

I think there's not much tradeoff, if you rendered in both eyes at once you'd want to optimize your slice batching size thing to be smaller so that the draw calls ended up the same, but if it was some really small particle or in the far distance with few slices, it might turn out to save a few draw calls

but fog particles aren't expected to be a lot of the draw calls ever I don't think

[sturdy coral]

try with instanced on an no particles in the scene, just increase global fog density

to make sure it is a particles-only problem

[alpine arrow]

so, there is no frame drop, but it seems like the GPU is doing some heavy work

[alpine arrow]

yeah, with instanced on, no particles, and high fog density it works fine

[sturdy coral]

there are lots of parameters you can tweak to get that time down

[alpine arrow]

im sorry, i'm not quite familiar with the terms likeslice batching. could you elaborate a little more?

[alpine arrow]

oh, really? everybody told me that fog particles are super heavy in VR, do you have any tips for bringing the gpu workload down?

[sturdy coral]

the fog is a like a pyramid of slices extending out from your eye, and the particles have to rendered into each slice

[sturdy coral]

that's the settings I'm using; with historyweight=0.98 it will be really slow to update if you have it on moving stuff or have shadowed fog with moving things through the shadows though

lowering the history weight will increase the responsiveness, but also increase aliasing/flickering

[alpine arrow]

oh, that's pretty neat! i'll try tweaking them. Do I just add them in the defaultEngine.ini?

[sturdy coral]

yeah, under [/Script/Engine.RendererSettings]

[shadow radish]

we disabled steamVR plugin and may have gotten better performance now. We haven't profiled but it seems to feel slightly better packaging the project without the steamvr plugin.

[sturdy coral]

are you using virtual shadow maps?

@alpine arrow I tested in 5.2 just now and the particle system I have works in both eyes. are you on nvidia?

[alpine arrow]

Yes, im on nvidia. Does it work with instanced stereo on? cuz it would be even more optimized if it works

[sturdy coral]

yeah instanced stereo is on

I guess try moving your particle system to cascade and see if that works, that seems to be the only difference

[alpine arrow]

alright, i'll definitely check them out!

[sturdy coral]

that's the only one I have, just drawing a single sphere of fog somewhere with all the animation of it in the material itself

[wheat wyvern]

no VSM are not activated

[alpine arrow]

I cant find cascade particle system, do i have to add a plugin?

[sturdy coral]

they might have hidden it from the UI since cascade is deprecated, I'm not sure how you can create a new one without copying an existing one now

you can maybe migrate one from a legacy sample project if there is no other way

[alpine arrow]

i see, I'll figure out a way

do you by any chance have more tips on optimizing in VR? if I go along with instanced stereo off, I hope to improve the lost performance. My project might get heavier with niagara added to my chaos destruction

[sturdy coral]

if you are using forward rendering that might be another difference from me with respect to the particle thing, I'm using deferred

you can try that too and see if it fixes

[wheat wyvern]

I'm using deferred, should I activate VSM ?

[sturdy coral]

I'm not sure, it had bugs in vr in the past but I think they are mostly fixed, but if you are using stationary there are a lot of caveats with VSM I think which is why I asked https://docs.unrealengine.com/5.0/en-US/virtual-shadow-maps-in-unreal-engine/

search stationary in there

[wheat wyvern]

Well, I can set my dir light to movable, perf impact is quite low on PC VR

otherwise it's just more than quite annoying for movable objects....

I am converting a copy of my project to give this a try

[alpine arrow]

oh yeah, I have forward rendering enabled. Wouldn't disabling it cause significant performance drop though?

[sturdy coral]

yeah, but just to test why you are getting differences from me

[alpine arrow]

ok, i just got everything compiled and check with the forward shading off, but it still renders differently for each eye

Also, I just checked with the cascade particle, and it seems like it doesnt get rendered at all. Plus even more performance drop than niagara

[sturdy coral]

that's strange, does the cascade one work in the 2d editor viewport view of your level?

[alpine arrow]

yeah, it appears in the 2d viewport, but it barely makes a difference, even though they have the same settings and material... I had to toggle the visibility a couple times to see the difference

[quasi loom]

Do I need to wait for oculusxr plugin to get updated to 5.2 before I switch my project over to 5.2?

[coral swallow]

not sure if you've found a fix or if im reading this right but If youre running an oculus headset through unreal with the steam vr plugin the view gets really wishywashy. Both the SteamVR plugins and OculusVR plugins sorta dont work and are deprecated now in UE5 so it is best to just use the OpenXR plugin by itself and disable the other two.

[radiant sundial]

I see, well done in tracking it down!

[sturdy coral]

that's strange, maybe it is feeding alpha into material from the particle system differently somewhere

[shadow radish]

thanks simply--yeah we have been seeing that we seem to have better performance disabling the steamVR plugin, I think that was our holdup.

[shadow radish]

it was steam devices that were having poor performance for us with that actually, the oculus ones were working fine.

[quiet badger]

I'm using 4.26

[wraith sky]

by OpenXR you mean Pico OpenXR plugin?

[stable shadow]

@wraith sky No just the default OpenXR plugin comes with engine

[wraith sky]

yeah, Pico only added support in Feb 2023

Sorry, have not noticed you're on 4.26

[stable shadow]

No problem, I'm just thinking of enabling those plugins and ignoring the PICO,
Last time I sent my project for Steam review they said Windows Mixed Reality controllers are not working, and I don't have access to any Windows Mixed Reality devices

hi, does anyone can help with changing the default manequin XR to another model (I need hands not gloves) ?

I just do not know what to do, the open xr thing is new and complicated for me

[alpine arrow]

well, i guess ther's nothing i can do... thanks for helping out tho

[sturdy coral]

I just tried in 5.2 creating a niagara system from scratch in the vr template and only see it in the left eye, but with my cascade system migrated in from my other project it works:

(niagara is the sphere, cascade is the cloudier looking thing)

@alpine arrow would have to debug to where niagara is rendering differently than cascade, but I won't have time unless I ever have a real need for a niagara volumetric fog system; see if you can see your cascade test better when you put a big value (like 10.0) into your extinction pin in the material

and then send them a bug report if you can get cascade working too

[trail shale]

How is VR (Using Valve Index) in 5.1 (I know 5.2 just came out) - I'm still on 4.26 but I'd like to start the process of updating my project to an engine version released in the last 2 years

[wraith sky]

for me 5.2 just stopped to work completely, mentioned above...5.1.1 works fine (even with lumen)

[trail shale]

saw that - was this from a hotpatch for 5.2? or did it not work EVER for you?

im trying to do capsule rotation similar to how i have the capsule follow the camera but running into a weird thing where if im off from my origin point whenever i rotate my head my hole actor move in a direction relative to the distance from the vr origin... i thought maybe doing rotate around a point would fix it but it just sends me off the map for some reason. Any ideas on how i could fix it with my setup here? https://blueprintue.com/blueprint/kyvpxdrb/

[wraith sky]

TY for the tip, but it seems it's not enough, it also require active HMD connected (i.e. powered on Index in my case)

[jade kettle]

Looks like you're applying the rotation the actor rather than the capsule in particular

As adjusting the VRCalibration will affect its children too

hi there! has anyone else run into the issue that their ue5 vr template does not recognise button, stick and trigger inputs?

I booted up the vr template and for some reason while the head and hands do move to match the motions of my headset and controllers none of the inputs work at all, I cant grab onto objects, the fingers dont move and I cant teleport either

[silk lava]

Creating a new level, added a static mesh floor i modeled, and also tried the base level template. Added the VRGamemode the nav mesh and the player start and I can not teleport around the map. I get this error when ever i try to teleport. (Unreal 5.2, using the VR Template as the base, no modifications to the blueprints other than new level). Getting Error

LogHMD: Warning: GetPlayAreaBounds xrGetReferenceSpaceBoundsRect with reference space XR_REFERENCE_SPACE_TYPE_STAGE failed with result XR_SPACE_BOUNDS_UNAVAILABLE. Returning zero vector.

Any ideas ?
I am now booting 5.1 to try the same and see if it works there.

[gleaming oriole]

does quest 2 support EOS?

[silk lava]

Looks like it happens with 5.1 as well, added the meta XR Plugin and it stopped giving the error, but now hands are off and the teleport isnt working. I must be doing something wrong with the teleport so i will debug that.
Thinking the errors might be with the Oculus 53 drivers.

Your play area bounds is not set up, or you've disabled it. That's an error returned from the runtime, so not related to UE

[hallow knoll]

You're very unlikely to receive help by just asking for help. Post the question and if someone sees it and they know the answer, they might be able to provide you an answer. If the question is vague and doesn't contain enough details, very few will ask follow up questions. Also, check out the PICO VR Developers Community: https://discord.gg/E7E3WHJh

@hallow knoll just because this crash has plagued me and many others lately, I have a 5.2 project with lumen, nanite, virtual textures and substrate that has been killing my will to live over the last few weeks, dxgi device removed or hung. Today, I came across a post saying to change these two settings

I have not been able to crash it since

Would be interesting if this solved the issue for others and maybe it could be made default for UE

[hallow knoll]

We don't manage the users Nvidia settings. I'm curious though if both of those settings are required or just one?

[hidden orchid]

Yeah, know that GeForce experience set stuff for individual games and apps and they'd probably sit up and listen to you guys. So the nvidia driver threads on reddit has this guy who always gathers really good info on nvidia issues, down to bios, driver and registry settings, he got me on to set prefer maximum performance which helped a bit, but went deep into the rabbit hole today and found the low latency mode one and that's the one that finally solved it. Incidentally it also fixed the infamous pc last of us port

It's one that I wouldn't have tried tbh, because I dont do competitive multiplayer much these days

This is on a 4090 btw

Hi! Does anyone know why hand tracking does not seem to work whenever I export my game as APK and load it onto my Quest 2? In the editor hand tracking works just fine

[silk lava]

When I add the MetaXR Plugin this error disapears, which leads to say it could be in the OpenVR plugin. I have gone through resetting the guardian and bounds, both stationary and roomscale and have the same issue. Tested in Unreal 5.03 VR Sample freash template and it works fine.

[little terrace]

Hi there! I'm new to unreal engine and VR development and For my school project, I am developing a warping system in virtual reality (VR) using the Oculus Quest 2 and Quest Pro devices, along with Unreal Engine 5.1.1. The objective of this project is to create an immersive experience where the main camera image is dynamically warped around a black dot that can be positioned at different locations on the user's eye. I have already attempted an initial solution by adding an extra camera that captures a 2D scene and renders it onto a render target. This render target is then used as a material on a plane mesh, which has predefined morph targets to warp the image around a predefined position, such as the center. This could probably be achieved in a much better way as well.

However, I would like the warping system to be more dynamic, allowing easy adjustment of the black dot's position for flexible warping around different spots on the user's eye. I am looking for guidance or suggestions on how to achieve this dynamic warping effect within the given hardware and software setup. Are there any specific techniques, APIs, or Unreal Engine features that could help me accomplish this goal efficiently and effectively?

The first image is the mesh I use, the second is without warping and third with warping.

Hey guys, quick question - how do we check if the player has a VR connected or not?
Is the node "is head mounted display enabled" enough? Thanks

perhaps in wrong place? you can open the build folder and check if its in proper spot

that should be enough.

[worldly peak]

How do you control 2 clients with the same headset in the VR preview mode or is it even possible? The motion controllers and the headset are both locked to the first client and they can't be used with the other one separately

[dreamy ivy]

not possible, you can only preview with 1, it's why multiplayer dev is such a pain. Last I heard though, they were fixing this with 5.2

[worldly peak]

You heard it might be already fixed in 5.2?

[dreamy ivy]

I think @hallow knoll mentioned it during this video but i could be wrong. https://www.youtube.com/watch?v=vT1T2unF8EI&ab_channel=UnrealEngine

[spiral marlin]

sometimes my 5.1 project doesnt detect my motion controllers. the only solution I've found is to restart computer. I am using Valve Index controllers. Anyone know of solution that doesn't require restart?

[serene ridge]

I'm running into an issue with audio going out my computer speakers instead of the Rift headset. Is anyone else with a Rift experiencing this, and do you know a fix? This is with OpenXr & UE5.

My UE4 VR project works as expected -- audio goes to the headset. But that is running through Oculus, not OpenXR

[hallow knoll]

We implemented a switch in Editor Preferences that allow you to pick which client gets poses and input, so you can test as the 2/3/4 client that joined. But you can't control two at the same time, or switch between them at runtime

[hidden crest]

I've been interested in this as well (simply altering the VR FOV) but never uncovered anything conclusive. I was imagining a similar approach to what you are taking but also thought there must be a better way. I hope you report back with any interesting findings and will do the same when/if that part of my project happens.

[little terrace]

I'll do my best, but since the project is coming to an end within a couple of weeks, I can't guarantee how much progress I will make.

[dreamy ivy]

That makes sense, thank you. I knew you wouldn't be able to control both but wasn't sure if you could select a window and switch. Good to know you can do it before testing though.

Hi Guys, i have an interface that is invoked by the player with a button. The problem is that when the player invokes it, with some element very close to him (a box), the modal comes out and is interfered by this element. Is there a way that the interface is not covered by any element of the level when it is invoked?

[ionic tulip]

Hi there, currently trying to work on a project for quest 2. I packaged the project and installed the apk and was working fine couple hours ago, now when i open the project it does the loading 3 button icon then just return to the quest 2 home screen. How can I access the crash logs within the quest 2?

[sturdy coral]

you can render it translucent with depth test off

or if it is an xr overlay I think there are settings to choose if depth affects it

[round cliff]

If I disable depth, the interface becomes translucent but is still obscured by level elements.

[sturdy coral]

blend mode must be translucent

for disable depth

[round cliff]

How can I do this? in widget options

is here?

[sturdy coral]

no, in the material. you can undo any changes you made on the widget, that's the wrong place

[round cliff]

ok ty

[round cliff]

works !! thank you

[round cliff]

By doing this my pointer no longer works in the interface since it is now behind. Is there a way for the pointer to be over the interface?

[shadow nimbus]

What would be the proper way to move VR hands to a third-person camera and back to a first-person one? Is there a way to set the new origin of the VR hands?
It kinda works by doing AttachActorToComponent on the other cam, but attaching that way causes hands to move when moving the head. (I'm on UE 4.27)

[sturdy coral]

you need to change the trace channels around, I don't remember the details but you want one that isn't blocked by world, there is a built in UI one that might work

[round cliff]

[smoky pollen]

I'm seeing a weird artifacts in VR under a specific condition. When there's a foliage under the wires and I'm closer to the foliage, I get a 'ghosting' of the cables and several other parts.
I use forward rendering and I tried MSAA and TSAA but I see that on both. Anybody knows what it's caused by? (Quest2 on link) (there picture doesn't show the ghosting/artefacts I am unable to screenshot that.. but it's like a jittery ghosting)

[smoky pollen]

Ah I see, it might be a framerate drop

[smoky pollen]

DO somebody have some good DefaultEngine.ini rendering options for PC VR (UE 5.2) to go from?
I've found these on the internets, but I'm sure there's plenty more

[sturdy coral]

try the settings from the vr template

[smoky pollen]

Ah, I haven't realised that it might have different config than the other templates. Will do, thanks

[sturdy coral]

yeah that sounds like it was probably the motion reprojection stuff that happens during framerate drops, it's motion estimation isn't as fine grained as the resolution so it can warp thin stuff and silhouettes around a bit

Hey Everyone, trying to figure out how to use UBIK on the new VR Pawn in 5.2
Got this here tute is quite good: https://www.youtube.com/watch?v=k4AJcwSbPZw

Watched the twitch stream by victor and alex from a month or so ago talking about subtle changes in the vr pawn to better track play space but I can't quite get my head around where to put thing in this new hierarchy :/

[celest basin]

Ah... nvm 🙂
Easier than I thought it would be

I can't see any button to press to enter the VR editing mode.
Any tips? The documentation seems to me like it's just supposed to work without any way of entering the mode.

Hello Guys, Is anyone developing for ios(Arkit) using Unreal Engine ?
I would like to know the challenges in building & publishing on the App Store.

[steady fern]

Dear community, I am curious to know about the best practice of matching the VR and physical environment(roomscale) through calibration of the coordinates between virtual and real.

I'm considering the following scenario:

• Playback of UE5 content using oculus quest 2 via Oculus Link
• I have several physical objects(300 x 2000 x 700 mm(WxDxH)) which are placed in the roomscale of 10 x 10m.
  I'm aiming to interact with physical object described above, primary to get haptic feedback.

I found so far following attempt in forum:
https://communityforums.atmeta.com/t5/Unreal-VR-Development/Room-scale-matching-IRL-location-How-to-manage-Quest2/td-p/973463

Which seems to be one good example working pretty well.
At the same time the setup seems to be a bit bulky.

I'd be really appreciated for any suggestion or insights.

Hi, I have a problem with the integration of OpenXR Vive Tracker plugin in the UE 4.27.3, I can't compile it.
An function AddActionsSets in the OpenXRViveTracker class try to override an function AddActionsSets in the IOpenXRExtensionPlugin parent class.
But this function doesn't exist in OpenXR Lib on UE 4.27.3 but exist in OpenXR Lib on UE 5.0.3 . I can't update it.
I try to comment this function and i can compile it, the component is here but of course it doesn't work.
I check the GIT repo and this is the only version of the plugin OpenXRViveTracker and this is UE4 version.
https://github.com/ValveSoftware/openxr_engine_plugins/tree/main/unreal_engine/ue4/OpenXRViveTracker
Anybody have and idea please ?

[dusky sedge]

Hi,
I'm writing a ball game that has a score system that I implemented using a state machine. The score is dependent on the interaction between two players, the ball and the court. I am wondering, is there a go-to method for creating tests that require multiple interactions with players and the world?

Ideally, I would like to simulate multiple games, with a pre-defined score, and see that they do no fail. Kind of like unit-tests for UE VR.
Is there a go to plugin or anything for that?

[hallow knoll]

We natively support ViveTrackers in 5.2 now: https://dev.epicgames.com/community/learning/tutorials/LdR2/unreal-engine-how-to-use-vive-trackers-in-ue-5-2-and-later-versions

[hidden orchid]

Btw this ultra latency crash solution was a red herring, it helped, but the underlying problem was vertical pcie cable, havent had a crash since, left it for 24hrs to prove the point

[gray karma]

But for the 4.27.3 ? This is dead ?

[jade kettle]

4.27 should have support via the SteamVR plugin

unless you're going for OpenXR on 4.27

Then the OpenXRViveTracker plugin is only officially integrated in 5.2

[real needle]

Does anyone know why my LODs stopped working in 5.1 on Meta Quest?
It seems like the MinLOD is always 1, no matter what I do. I can't get LOD0 to work.

Found it. It was the View Distance Scalability setting 🙂
Didn't know it had an effect on LODs

Do Motion controllers not update their rotation/Location after beginplay?

When set as an attachment to a scene component

[cinder widget]

Is there a "virtual" VR headset that you could use to fool SteamVR into thinking there was a headset? What got me thinking this way is that my Pico 4 has been flakey to keep UE Play VR launch button enabled. Sometimes I want to launch the play button but not actually use my headset. If we had such a simulator, the next feature would be to capture headset and controller data from the real Pico 4 and replay it back with the simulator later to replay test data. Sorry if this is a really dumb question.

[tired tree]

@still basalt they update on tick

begin play is too early often anyway to get relevant tracking, depending on how you have things setup in app

[flat shoal]

Is it normal to get 7fps in VR using lumen on a 3090? Never tried it before 5.2, but since it now supposedly works I wanted to see... however, it's catastrophic performance. In editor viewport I get 40-70fps which isn't great either though, so I guess it's a bit optimistic to expect similar VR performance...

[jade kettle]

It is? Nanite and Lumen performance is rather inconsistent, I never got it to work properly with good performance

But then I saw and tried out this demo https://www.youtube.com/watch?v=G7xzlBv8r64

And it had really good and stable performance. I asked the maker how he did it and he was just rather 🤷‍♂️

[flat shoal]

That's probably just a huge 3D scanned mesh. I have hundreds of smaller meshes (Datasmith imported).

[still basalt]

So why am I unable to set controller or camera relative location/rotation?

I do have my camera using pawn control rotation

But whenever I turn the playspace origin that the camera and controllers arae attached to, the Controllers turn, but not the camera

                      HMD
                        |
LController------- PSpaceOrigin--------RController

Rotation of the PSpaceOrigin doesn't rotate camera or controllers

Unless it's the root component, then it works for controllers only

Or should I not have the Camera be using the Pawn control rotation and instead have an input action for all that?

[lofty wagon]

Hi, has anyone encountered an issue that stops you from closing the virtual keyboard as shown in the video attached? I do not show the widget I am editing but I selected an editable text field on a widget. I have tried the same thing with other widgets, and other text fields. I can't close the virtual keyboard if I update the text on any editable text fields on widgets. This is running on a meta quest 2, built on UE5.1. Thanks

[coral swallow]

anyone figured out a way to prevent player rotation spinning out of control if you are looking straigh down or into your physics chest? Ive got the player rotating with the hmd nicely but i just want it to not freak out when hitting that specific point

[lofty wagon]

I've discovered that the issue only occurs when there is a preview bar of what you're typing. When the text field is a password or if the keyboard language is not english, then there is no preview bar and the keyboard closes normally. Does anyone know how to remove this new preview bar or override the keybaord language? Thanks

[sturdy coral]

when looking down (dot product against -z down to see), lerp from the forward vector of the headset to the up vector of the headset for determining direction

in other words, as the player looks more and more down, gradually shift to using the vector in the direction out of the top of their head to determine forward direction instead of the vector in the direction out of their face

[sage gulch]

when you localize a stereo sound asset does it get submixed to mono or what?

i doubt it will be the game changer everyone is expecting... It'll be similar to the quest but with the price of a cosmos. and with apple making developing on their platforms so annoying its probably gonna lack content

Does anyone have experience working with the HTC vive Focus 3? I have a project that can be packaged and transfered to the headset via cable, this build is built in UE 4.27 using the openXR-android plugin vive provides. I am trying to get the template for 5.1 to work on the headset. One error I get is the headset is built for occlus. When I remove the occlus builds from the list in the advance build section. The project will open but the player is stuck upside down. And the screen is basically broken. Any thoughts would be helpful!

[zinc cipher]

Hey, I want to work on the map of my vr project while I don’t have my googles with me, can I use a normal pawn in a vr project?

[cinder widget]

I am curious about this as well! One thing I've heard is for fast iteration times, it is better to break up your project into multiple small projects. If that is true and a common practice... I guess you could have a flatscreen FPS project and work on your assets there.

[hidden crest]

Yes.
I always develop my VR projects using a VR pawn and a FP pawn that mimics most of the VR interactions. It makes developing a lot easier but of course you can't properly simulate VR without actually using VR. I also use the Character class as my base class for both pawns so it makes sharing functionality between the pawns pretty easy.

The other really big positive is that you can potentially release your project with a FP mode, expanding your user base substantially, also making it easier to share with non-vr people, etc.

[zinc cipher]

I just want to be able to walk around the map to check materials and world partition settings so no blueprint stuff

[chilly yoke]

Well, it looks like Apple teamed up with Unity on the Vision Pro. Hopefully there is room for UE - but who knows what will happen with the glasses at $3500.

[silver brook]

Very well done presentation and captures a lot of the end goals I'm sure we all hope for

But no OpenXR collobration? No Unreal Support?

Also what is the FOV?

Can't wait to see how it performs real time and not in an Ad

[cinder widget]

Definitely light on details. Looking forward to more of a roadmap about SDK, simulators or other ways to dev w/o a device

[coral swallow]

why would they team up with the company they are in an active lawsuit with over unlimited software

[silver brook]

For the same reason competing companies teamed up and formed OpenXR?

[coral swallow]

this is apple we're talking about

they dont do "open"

[whole nimbus]

Anyone know of any tutorials that go over climbing or vaulting in vr? Mostly the vaulting, not sure whether to approach with motion warping or somewhere in the grab component.

And another huge one, if anyone knows any resources that go over 3 axis motions as input, so like if the player draws a circle in the air, etc.

[whole nimbus]

Like for hand or head gestures

[jaunty yew]

No unreal support for Apple VR?!?!?

[whole nimbus]

Theres still time.

[atomic drum]

It’ll have an sdk, Epic just need to give some real resources to VR/AR tbh

[jaunty yew]

No mention of any sdk for unreal here https://developer.apple.com/visionos/?elqTrackId=c36920530dfb405e9b087e64bbc9583c&elqaid=4647&elqat=2

only unity SDK!!

[coral swallow]

the 10's of users will have more to worry about other than content

[jaunty yew]

Can we sue apple again please

[coral swallow]

and make them hate epic more?

[sturdy coral]

I'm sure it will eventually support it but they were snubbed out from the lawsuit. That commit + recent foveated nanite from 5.2 could be good with it

[subtle raft]

Can the Vision Pro even render anything but a 2D plane for a screen? That's all they showed it can do...

[jaunty yew]

Apple needs to accept unreal support for their new VR OS now!

Unity isn't even open source

[atomic drum]

Epic make the plug-ins not Apple.

The Unreal leadership team probably needs to take a closer look at the progress of AR/VR within their engine tbh.

[undone coral]

Yeah, but they can't use them or submit to the Apple store if Apple says no. It's Apple payback for the Epic lawsuit on fees. May change though. I'm wondering if they'll even allow proper immersive 3D VR experiences anyway. They showed nothing that you could really call a proper 3D VR experience. It was all 360 videos or floating 2D games and screens. Bizarre. Why would you plug in an XBox or Play Station to play "2D" games in a powerful headset? All that power and all they want you to do is watch TV or browse the web.

[atomic drum]

We don't know what Apple has said to Epic regarding Vision. From looking at where UE5 is for AR/VR, it's not great.

I’m sure Vision can do 3D, kind of a given isn’t it?

[undone coral]

True. But they are not the best of friends.

[undone coral]

Of course, you're right, but Apple seems to want to skip that entirely. It's very weird. We've made the most powerful headset with the best resolution in the world. Now let's just watch movies on it...

[atomic drum]

Who cares if they're not friends? They're tools. Politics shouldn't get in the way of a product's day-to-day. If Epic doesn't bother, people will move to other engines.

[undone coral]

I hope you are right.

[dense geode]

They showed 3D content in the presentation. The heart, the F1 car etc.

[undone coral]

Do you remember when Steve Jobs was annoyed with Adobe though about Flash. That impacted a lot of development/support for years...

[atomic drum]

Flash was trash tho

[undone coral]

Yes it was.

[dense geode]

That trash made me a lot of cash back in the day 😂

[atomic drum]

They killed it then hired the dude to do iWatch 😂

[undone coral]

Is that true? that's brilliant!

[atomic drum]

He got um with supporting that joker Swift language, fun times Apple

[undone coral]

Yeah. But that's it for an entire presentation about a VR capable headset! Crazy if you think about it. The rest was just floating screens or 360 videos.

[dense geode]

I think they’re right on with the things they showed. It was very people and productivity centric. Not gaming first like Meta.

It’s true tho they could’ve showed more cool 3D stuff

[atomic drum]

You think Unity really runs on it yet? That team is even more dysfunctional than Epics.

Apple needed to show stuff that iOS App creators make, that’s mostly 2D apps.

Excel in Vision is like a waste of tech, but they needed to show it.

Its a private video player "wink wink" privacy "Safari is the only incognito browser that's for real privacy", say no more 🤣

[dense geode]

[dense geode]

Tim and Sydney Sweeney Collab when? 😦

[jaunty yew]

we need apple VR support now, apple can't do this to us

[atomic drum]

Tim needs to continue supporting the UE team in creating a great engine. Additionally, he should persist in pushing forward as monopolies are not cool.

Apple created the HW, up-to Epic to support it.

[jaunty yew]

How will epic support it if the SDK won't support unreal engine?!?

the apple sdk

[subtle raft]

ahh I only watched a short recap video

[undone coral]

Unfortunately it's Apple computer vision algorithms support, nothing to do with the new headset 😦

I wonder if there will be support for it eventually. Unity already had an edge in vr (in popularity) so this news kind of sucks. I don't want to go back to unity, I like ue better.

Is there a way to smooth the Head (camera) rotation for screen recording purposes (PCVR)? I tried to add a Spring Arm with Smooth Rotation, but I couldn´t see any difference.

[vale ridge]

Hello everyone, you’ve any advise for me?
I'm having problems with the height of my VR player.
I can never get it to be the same height, it always spawns with the camera at a different height.
Do you know any way to block this height and make it always spawn at the same height? Regardless of whether the player is standing or sitting.
Thanks!

[warped mesa]

Yes, on the spectator camera. There was a bit about this not long ago, sec

https://www.youtube.com/live/vT1T2unF8EI?feature=share&t=950

So you would record using a spectator camera, and you'll just be the camera man 😄

[unique cloud]

That's brilliant! Thanks a ton!! I'll definitely check how to do this recording while in airlink. 🙂

[whole nimbus]

Does anyone have a best practice idea of how to do gestures in VR? Like, say head movement triggers a function, by looking up. I could use the dot product with a vector sticking off the top of the head, but running this calculation on tick cant be the best way of doing it. Im trying to figure out how to do hand and head gestures as input. There are a few marketplace assets that do this, but they seem similarly convoluted, using machine learning to verify the gesture.

Maybe the keyword would be gesture input or gesture locomotion

[prime eagle]

Hey. Absolutely brand new user. Been tinkering 5.2 for about a week. First question. Is Edit in Vr still functioning? Is it worth pursuing. Very curious. Thanks.

Also I am messing w the VR template and can’t get rid of this weird shadow. Any tips?

[magic abyss]

@prime eagle I don't even see a light in your scene. Did you bake then remove a light? If you are brand new I would recommend going through a lot of tutorials https://dev.epicgames.com/community/unreal-engine/learning . Lighting/shadows can be a very complex topic.

[prime eagle]

Hey Tim. Thanks for responding. Maybe is a baked light from VR template in 5.2. Yeah im new and have gone through a lot of tutorials…I’ll check out more and see what’s up. Any thoughts on VR Mode editing? I’m coming from an in VR building program so am hoping it works. For rough strokes at least. Cheers!

[magic abyss]

In the 5.1 release notes it says:
Access to the built-in editor VR Mode has been removed. Virtual Scouting is the recommended alternative for all users going forward.

However, in the Editor Preferences under General, I still see a VR Mode. So maybe it works, I've never tried it.

[prime eagle]

Thanks again Tim. Have a good one.

anybody want to humor me for a conversation about vr inventory systems / slight rubber ducky session?

I've been chewing on this half baked idea about setting one up inventory based around fragments or json data so it can be flexible for mods or something.

I really dislike having hardcoded / closed ended systems for something like an inventory. Think about the practical purpose this serves in vr and the real world right, it's a friggen bag you put shit in. Just need to keep that idea in place, have some sorting and simple logic, save load, and convenience for gripping stuff.

[burnt folio]

Anyone know if the FSR2 plugin works with OpenXR? When I set the quality modes, the screen itself gets smaller inside the headset without upscaling to the full resolution. So it gets smaller and smaller with each level.

Have temporal upsampling enabled per the instructions.

Example:
Quality level 1 and Quality level 3

[exotic carbon]

I certainly hope so

[burnt folio]

Seems like it only affects the landscape visibility... the skybox is actually visible outside of it unchanged. I tried it with the default VR project and don't have as much of a problem, but the shadows are misplaced for objects and only appear at the top left of the view.

is there actually anybody that can say they prefer hand oriented locomotion the head oriented? if so, why?1

[flat shoal]

This was a CAD import via Datasmith, exported as FBX to Blender and then converted to USD from there.

[coral swallow]

the open xr plugin finds which vr system you have set as primary and will use that data rather than needing a bunch of diferent plugins. if you go into the oculus pc app you can set the default openxr runtime to oculus if steam vr has changed it

[ember forum]

right what i mean is, i dont have to do that for pavlov it seems.. but maybe i didnt try i have both oculus and index, im going to try using oculus openxr with ym index and see what happens

hey guys, I'm a total beginner with Unreal Engine Never used before, I want to make a 360 VR world and present it live, I have oculus vr so I can make a VR streaming server and everything, can someone tell where can I find free to use VR worlds or generate easily maybe.

Any help or advice is highly appreciated

[coral swallow]

the reason you dont need to do it with pavlov anymore is because they use only the openxr plugin in unreal

[quiet swan]

Is anyone using landscape and foliage for their maps in VR? Or is it to much power

[granite willow]

Will there be an announcement regarding to Apple Vision Pro support?

[wary bridge]

Hello, I’m new to Unreal Engine and im trying to make a first person view game that runs on a PC but that supports a VR headset to be plugged in. I dont need to use the VR controllers, just the player to be able to move his head around.

Is it possible by default or do I have to do something? I dont have an headset to try

[granite willow]

Yeah it's possible. Just check LockToHmd on first-person camera and should be good to go in most cases.

[iron barn]

Hello. I'm trying to do something that involves adding and removing widgets after a number of inputs, but I can't go from one widget to second widget without the VR blacking out on one of the "eye". Here's the example of what's happening

Is it enough for me to add and remove widget from widget blueprint, or do I have to do the adding and removing from the 3d widget blueprint?

[vocal knoll]

Hello everyone, hope you are doing good.
I have a problem. I have an basic cube in my VRTemplate of UE 5.1 scene and I have added a sphere collision to it and made it OverlapOnlyPawn.

It still doesn't detect collision when I have a print node at begin overlap for the cube.
Can anyone please help?

[hallow knoll]

You can't use screen space widgets for VR. You have to use a 3DWidgetComponent. You can look at how the Menu in the VR Template is put together as an example. These docs from 4.27 is still relevant as well: https://docs.unrealengine.com/4.27/en-US/InteractiveExperiences/UMG/HowTo/InWorldWidgetInteraction/

[hallow knoll]

Does the pawn have collision? If you're using the VR Template and the VR Pawn, there's no collision by default

[vocal knoll]

Yeah I tried adding a capsule collision and setting the collision to use pawn, still doesn't seem to work

[iron barn]

I did, was able to use 3DWidgetComponent, then I faced a problem when I wanted to load another widget. Basically I want to call widget B from widget A, but 3DWidget doesn't allow me to pull widget B from widget A

I was able to solve the problem by casting VRPawn from widget A's BP after I set widget A as the 3DWidgetComponent, tho I wish it can be easier

[hallow knoll]

Did you attach the collision capsule to the camera component?

[vocal knoll]

No I didn't, I thought the capsule would move with pawn by default?

[hallow knoll]

The Pawn's root component won't move when you walk around in your physical space, only the camera component will

[vocal knoll]

Oh I get it now, let me try this. Thanks a lot for helping me out btw.

[sturdy coral]

MotionControllerL->bDisplayDeviceModel = false;


warning C4996: 'UMotionControllerComponent::bDisplayDeviceModel': bDisplayDeviceModel is deprecated. Please use the XRDeviceVisualizationComponent for rendering instead. Please update your code to the new API before upgrading to the next release, otherwise your project will no longer compile.```

What's the right way to disable this now?

just not attaching a UXRDeviceVisualizationComponent on your own, or does it attach one somewhere based on some other setting?

[sturdy coral]

well just removing that line still seemed to keep it disabled so I guess it was already the default

[iron barn]

I'd like to show one camera in my VR and another camera in monitor viewport. Both of them shows different things but is displayed at the same time. Is there any way to do that?

[iron barn]

I tried using VRSpectator as well as VRPawn, but when a widget is shown using the spectator camera, the input to the widget is very laggy and sometimes it doesn't register the input at all

[hallow knoll]

We kept the "old" Device Visualization functionality in the MotionControllerComponent as we don't remove features from one engine version to another. But you're correct that the "proper" way to use/not use it is to add/not add XRDeviceVisualizationComponent. In 5.4 we'll remove the visualization functionality from the MotionControllerComponent. The benefit w. the new component is that it works as one would expect a PrimitiveComponent to work w. collision, materials, etc.

[sturdy coral]

nice, will be good to be able to change materials on it more easily

[ionic tulip]

hi currently trying to detect when the user removes their oculus headset so to pause my game, i used the event for HMDRemove from head delegate back in 4.27 and it worked fine. but now I have upgraded my project to 5.2 and now it does not work, it calls HMDPut on head delegate once when project starts but thats it, anyone may have a sugestion on how to fix this?

[hidden crest]

If I'm walking, running, driving, playing basketball, etc... I don't move in the direction of my head, I move in the direction of my hands.

[trail shale]

I'm upgrading to 5.2 from 4.26 - can someone give me a link to something that is a primer/update guide for the whole Open XR and Enhanced Input System - I've been using Steam VR on Valve Index for the longest time

[opal harness]

Question: What is the purpose of using "XR Device Visualization Component" when we can use Static Meshes instead?

[rocky nexus]

it probably is a bit fancier than simple static mesh

[dreamy ivy]

https://youtu.be/m4SKzpJfATc

if anyone needs it.

[hallow knoll]

It automatically picks the contoller model based on the interaction profile returned from the runtime. It was initially added as a "simple"-solution to have controller models "just work". In the future it'll be converted to use the OpenXR render model extension.

[vivid spade]

Hey guys has anyone here done procedural VR hand grabbing? Procedural fingers were easy to implement, I am suffering trying to figure out how to procedurally position items within the hand. So that you could grab it at whatever rotation it was at when you triggered a "grab"

After 3000 hours in MS paint this has been my best possible solution which works in most cases but not all, cant think through a foolproof system,.

[solid vortex]

does unreal eos support mobile now ?

[shrewd geyser]

I asked this in the EU5 channel, but was told this would be a better place to ask
There's some videos from about 6 years ago showing how you can develop games from within VR in UE4, mostly placing props in scenes. I just wanted to know if game development from inside VR was still possible in UE5?

[whole nimbus]

pretty sure this has been put on ice, I was reading up on that a few days ago. Maybe the same wave of algorithm inspirited suggestions hit us both, my takeaway is that it was shelved for now and has been asked about for years since it was mentioned

[shrewd geyser]

I was just thinking about it cause I was hearing about the bigscreen beyond, which tries to fix comfort and resolution, which were my biggest problems working in vr.
But them shelving makes since, I imagine there's still not a lot of demand for it.

[exotic carbon]

hey, is there a function to run a VR game in PIE without a headset connected, with a stand-in first person pawn or something?

[jade kettle]

VR Editing was shelved yeah, but a new framework is in development for XR development in the editor

So plugins can be developed for virtual scouting, level editing etc...

My impression is that Epic wants to shift these features into plugins rather than baking them directly into the editor

[delicate isle]

You can check if a HMD is connected then get the gamemode to return a different pawn if needed

I just use the same VR compatible pawn but add the HMD check inside it and handle keyboard/mouse inputs instead of XR controller inputs

[glad tide]

I asked this in another chanel, but thought this was a better fit when I found it. Currently UE5 crashes whenever OpenXR is enabled, even when I create a fresh project from the VR template
e: It was because of SteamVR, when I set Oculus runtime to be active all the problems went away

[slender grail]

Hey, I was wondering if any of you know a way to smooth controller movement/rotation? Currently there's a tiny jitter, which is accurate with the tracking, but it looks strange if you're holding a heavy object so I wanted to add very small amount of smoothing. Like a camera lag.

[glad tide]

Most common way I've seen it done is to have the object move towards the controller position like you would any other object, then you can control the damping etc.

[glad tide]

Has anyone done cockpit games in UE5? I am pulling my hair out trying to get the VRPawn to inherit the movements of my vehicle, it keeps being aligned with the horizon, every thread I find on this is empty

[slender grail]

Ohhh I didn't think about that, thanks!

[trail shale]

Where can I learn more about converting from SteamVR to Open XR? Finally upgrading to 5.2 from 4.26

[trail shale]

specifically, which engine version deprecates these but has a recommendation for which to use

[jade kettle]

Hey, when updating a project multiple engine versions, I suggest taking it version by version

if you didn't do it

Also always keep a version of the original on hand for reference, I'm afraid that'll be hard to figure what went into those pins without an educated guess

[exotic carbon]

Thanks for this

[jade kettle]

Not UE specific, but has Valve changed SteamVR's behaviour to always require Steam running iin hte background?

It used to be that you could run SteamVR without being logged into Steam

[trail shale]

I guess VR is different - Epic says they just recommend biting the bullet and updating as far as you can - backups notwithstanding - I'm using perforce so I should be able to diff to see the pins - though I'm not sure what it does if the function is deprecated - I'm assuming it shows it as normal since it's not be executed

[jade kettle]

ah hm, I just found the same documentation

i stand corrected then

[hearty herald]

Are there any requirements for 3d models for vr i should look at?

Im asking cuz i did create a simple vr demo with almost 3 meters tall containers u can stand close to, the container models looked ok, also looked ok on flat screen, but when i did go vr to check the scene it was kinda bad, seems like for a 1:1 scale i need to have better models as they will look bad up close.

When u find/use 3d models in your vr projects, do u have some up front set technical requiremnts for them?

What to look for to be sure it will be looking good up close in vr, especially if it is a large object?

Hey. Is ultra dynamic sky functioning in VR? Is it worth the $50?

And unsure of 5.2 compatibility

anyone know why the Mappable Input Config for OpenXR wont actually allow my inputs to work in UE5.2? I made sure it was set in the projects settings and set the contexts to my Input mapping config, specifically it wont work for my controllers, only for inputs such as a keyboard and mouse. im super confused as ive followed quite a few tutorials regarding this but the inputs dont do anything for VR controllers.

[past citrus]

Anyone knows why model with semi-transparent material cannot display correctly in quest MR model? Thank you!

[lost grove]

Is it posible to Access world outliner from PIE after pausing a session of VR PIE?
I have this issue where I start PIE session in my VR headset and I wanted to check properties of particular actor.
So I thought I would just pause the game, hit f8 to unpossess/eject and click on the desired actor in world outliner.
However it seems that f8 does not work at all for VR PIE sessions 🤔

Is there any way around it?

[jade kettle]

So what's your set-up exactly? Is it PCVR via a cable?

[lost grove]

yes
it is a quest 2 via cabel exactly

[jade kettle]

I don't immediately have issues with that, though I've never tried pausing

I also usually just use Shift+F1 to get my mouse to appear or alt+tab

[lost grove]

For me the PIE appears in brand new window/viewport, not the same as editor. Is it the same for you?

[jade kettle]

Yes it is the same for me

[lost grove]

Then it seems like the outliner from editor is not bound to the desired viewport, but to the level opened in my editor (some startup level, MainMenu most of the times)

[jade kettle]

I'm not 100% sure on that

I was under the impression that the Editor Outliner is oddly bounded to the new Viewport

[lost grove]

I will have to make sure

[jade kettle]

If that's not the case, you could use the Blueprint Editor to check the instance of your actor

[lost grove]

Could you elaborate on blueprint editor thingy?

[jade kettle]

So the thing I highlighted in red allows you to select a specific instance of a blueprint

That way you can check its flow, values and so on

[lost grove]

I never noticed it. Much appreciated

[jade kettle]

You're welcome!

So for example, if you have two gun instances, and one is shooting properly but the other isn't, you can specify which gun instance to watch and figure out why one is working and the other isn't

And you can do that while in PIE

[tender gate]

Can anyone point me to an example on how to get index controllers Finger tracking working ?

5.1+ by the way 😇

[woeful glacier]

is there a way to test VR performance without plugging in a headset?

usually when running in editor i can get smooth fps (75fps) but plugging in a headset is when the performance dips

[jade kettle]

To get a ballpark idea wrt rendering performance, you could set the new viewport resolution to match your headset resolution

Has anyone here have any success with upscalers such as DLSS?

afaik, DLSS still crashes in VR

[somber warren]

hello, i've been using playfab authentication for my Quest app til now, but i would like to make the proccess as seamless as possible.
so, is there a way i could use meta's authentication directly since its already loged in the system? or there is no way to retrive that information?

[jade kettle]

Are you by any chance using the Meta branch of UE?

[somber warren]

been considering changing into it, does it have the solution?

[jade kettle]

Possibly, I'm not familiar with what you're asking but it does sound like a very Meta specific question

Oh, PlayFab isn't Meta

[somber warren]

playfab is the solution i have now, i would like to change from it to using Meta's native authentication if possible in anyway.

[woeful glacier]

do i use one eye res or the combined resolution

Quest 2 should be at what, 4k?

[jade kettle]

Combined resolution

[sturdy coral]

You can make a benchmark with -emulatestereo, should cover everything but the compositor cost which is pretty minimal these days; you may have to manually adjust its projection matrix if you want it to match a given HMD

[burnt folio]

Even the latest version for 5.2 I still crash in VR with DLSS

[jade kettle]

Yeah, on the nVidia Dev Forums there's a thread on DLSS crashing in UE5 from January and there hasn't been a fix

[burnt folio]

Are you able to get any upscaling to work? Fsr / temporal upscaling on 5.2? Or does it glitch out and shrink the distance view as screen percentage goes down?

[jade kettle]

That's what I was asking here haha

[burnt folio]

Because I think it is actually an unreal engine issue that is causing the problem. Dlss only crashes because it checks for that problem and crashes before it happens

[jade kettle]

I haven't done a deep dive in it yet

Just DLSS in hte beginning this year

[burnt folio]

Ya, not at my comp atm, but the depth vs velocity extent bounds become mismatched. The velocity one correctly resized but the depth one doesn't. Dlss has a check that purposely triggers a crash if they don't match. I commented out the check and it does the same weird behavior as the others

[jade kettle]

Sounds like you did a really deep dive

[burnt folio]

Going to look into it more tomorrow and see if I can fix it

[jade kettle]

https://forums.developer.nvidia.com/t/dlss-in-unreal-engine-5-1-and-vr/237749/44

The DLSS+VR bug thread on nVidia, the devs actually respond to it occasionally

[burnt folio]

Ya I read that before, but I think the issue is on the unreal engine side. May be why they haven't had any progress on it

Since it works for them when they set the screen percentage before start, it likely starts the depth bounds at the correct value, but changing it at all during runtime will crash it because it will hit the mismatch check

Velocity extent bounds will update but not the depth

[jade kettle]

https://tenor.com/view/dis-belief-surprised-oh-gif-10085527

[burnt folio]

Will update if I find a solution tomorrow. Hopefully it's something simple like triggering the depth extent resizing at the same spot the velocity extent is being resized

Ah it's InSceneDepthTexture->Desc.Extent and InVelocityTexture->Desc.Extent specifically

[hidden orchid]

@hallow knoll do you know if dlss-fg is coming to vr at all?

[flat shoal]

I suspect DLSS (and foveated rendering) is the reason that Omniverse can run raytraced VR as well as it does (because I saw a lot of shimmering not visible in Unreal)...

[hidden orchid]

Hope that's a good sign, electric dreams went from 50-55 to 100+ fps with third person game mode with dlss 3 for me

That's with cinematic scaling in 4k

[zinc cipher]

Is there a way to know if a pcvr project can work on quest? I have a very big map so I’m worried about performance

[rocky nexus]

you run it on quest (or any other target device) and find out, there are no shortcuts

if the 'very big map' is a large landscape, than almost certainly it has to be replaced with meshes. landscapes perform poorly on quest in my experience

[bleak blade]

Can someone help me with this? im watching this video and he uses a node that doesent exist anymore can someone tell me how i can get it click on the vid to see the node the video is timestamped allready do it will show you where i mean https://youtu.be/fkW-svEaF-w?t=765

[vivid spade]

I used this tutorial as the base for my VR hands, hes just checking if the hand source is the right or left hand.

[bleak blade]

It's fine now I fixed it I just downloaded unreal engine 3.27 copied the thing and pasted it to unreal 5.1 they removed it for some odd reason

[vivid spade]

Does it still compile? The blueprint?

Might just want to refactor that into checking if the controller is equal to the left controller object or right controller object.

[bleak blade]

Yes it just created it when I pasted it it works fine

[vivid spade]

Hey if it works it works, nj

[bleak blade]

Yep

[slender grail]

Hey guys, my controllers stopped working for seemingly no reason at all. I can still view the scene with my headset (quest 2) but I can't do anything, it's like the engine doesn't see the controllers. The head of the player also is placed strangely lower. I do possess the player blueprint because my view is where the blueprint is placed.

Restarting the engine, pc and even updating from 5.1 to 5.2 didn't help. I've seen people online have that problem but there's no clear solution anywhere.

I've also updated nvidia drivers.

Well, it seems that I can't in fact possess the player. Just created a new VR template project and it works fine

[slender grail]

I've just migrated the VR pawn from example project and that one works fine, but I'm comparing every single checkbox and everything inside of the blueprint and it's all the same 🤯 wtf

[wicked flint]

Yeah and its solved now thanks bro 😇 be blessed

[hidden orchid]

Does that happen if you set antialiasing to none in project settings? Atm for me it's not crashing, but I'm getting weird behaviour where it's only showing the top half of the screens

Or 67% I suppose, which is what the blueprint sets it as, I've got a blueprint keyboard shortcut to set screen percentage, if I do it manually via the console, it crashes

Which is very weird

[burnt folio]

DLSS requires temporal AA enabled with temporal upscaling i believe, so I'm guessing it's not active and you are seeing the partial screen glitch. The partial screen issue is related to issue I described and seems to be an Unreal Engine issue. DLSS just has a check that exits the application if those extents are mismatched.

[hidden orchid]

I seem to remember a note in the dlss docs saying that there's a conflict with taa and dlss and that it won't work if it's activated

Or tsr I suppose

As in ue native temporal aa

It does make some sense that software taa would be an issue with dlss, they're sorta doing the same thing

[burnt folio]

ya, not temporal super resolution, but needs temporal anti-aliasing set as it requires "Temporal Upsampling" to be enabled which it can't be unless temporal AA is set as the anti aliasing method
