@real abyssyou need a Nav Mesh for the teleportation to work properly

[real abyss]

Is this the thing?

[real abyss]

But I can only teleport a little at a time，It's like moving slowly

Hey!
I have a few Vive Trackers that I need to use in VR in pair with some vr gloves in urneal engine 5.

I have succesfully been able to install the livelinkxr plugin on a Visual Production default Project, because it's the only one that shows the "visual production" option in the engine "window" tab.. I set it up to control a camera and it works there..

But I am trying to make this work on a sample VR project.. and I cant even find the live link tab so I can source my trackers...

in the screesnhot you can see, that there is no "visual production" or "live link" option... where do I find this tab in UE5?

I have livelinkxr and the steamvr plugin installed.

thanks guys!

[neon monolith]

So, I got it... Was missing a plugin.. all good..

But my right and left controller are not using my trackers as controlers...

But, replicating the camera setup, i created a blueprint that tracks on of them and put it inside the vr pawn.. and it is working.. i have a cube as my hand to test.. and i can flip the tracker around and it translates to the engine ok..

The ideal is for them to be considered controllers.. any ideas what A m i missing?

[glad matrix]

what i dont get is why there are so many low poly objects for standalone? https://i.imgur.com/3sc573M.png
in the wc room the q2 only renders what is visible. q2 can do 750k-1m tris per scene. so where is the issue?

they could have easily put 10k tris on that toilet.

[lean depot]

Hey does anyone know how to prevent models from drifting when looking away from a tracked image?

[tribal lintel]

That's true, in a completely blank experience, blanker then the unreal default level, you can handle 750k-1m tris per scene

[glad matrix]

culling???

[tribal lintel]

sounds like you haven't experimented much

[glad matrix]

not with performance on standalone vr, no. but i guess i can expect the worst nightmare ive ever experience in my life?

so what is meta talking with 750k tris per scene if q2 actually cant render that at all?

are they talking about a scene with 62000 minecraft blocks. each block has 12 tris. total 750k tris. lol and very simple materials

[tribal lintel]

yes you absolutely can expect a nightmare, but coming out on the other side with lots of valueable experience that caries over outside of mobile vr. your not going to find any answers to those questions. everything depends on everything else. what game logic, engine features, materials ect are happening will change how many tris you can handle, it's not a good baseline for measuring perf

[royal slate]

Does anyone have a good lead on why my Oculus-Vr/Unreal build using a quest 2 deployment will only work if I disable my meta plugin? Otherwise, I get a splash screen then a crash right to oculus home screen.

This is Ue5

And the default VR template

[white gulch]

Attempting to export a rather large VR experience for the Focus Plus and 3 units. I've been through a lot of tutorials on reducing overall package size, but even with all available known packaging options, I'm still looking at a 5 GB export and a failed cook as a result.

Is there ANY way around this limit? The experience has something like 60 levels.

Currently attempting ASTC export as an APK/OBB

[slender lynx]

I have the same problem with UE5 on android. On iOS with an iPad Pro there is almost no drift. Maybe an hardware problem?!

[sullen vortex]

OBB Limit is 4gigs, you will have to split it into more OBBS, DM if you need help on how to do that

[slim raft]

Does anyone here know what motion source to select on a motion controller component to correspond to a vive tracker that has been set to 'held in hand' and 'right hand?'

I can't get any motion from it in this role, but no other role seems to let me bind inputs correctly.

[slim raft]

Actually, I just wrote a simple blueprint to loop through all the motion sources. None work while the tracker is set to held in hand. Setting it to camera in steam vr, causes motion to appear when camera is set as the motion source in the blueprint. Perhaps Steam VR doesn't forward the pose along in this case?

[fathom temple]

Thanks for the feedback! That's the impression I had, glad to hear I might have a good pulse on it.

[sinful goblet]

Guys any body faced this kind of error using VR?
OpenXRHMD_Swapchain.cpp Line 93,
Failed to wait on acquired swapchain image. This usually indicates a problem with the OpenXR runtime

[slim raft]

Just to answer my own question, you have to manually turn all the poses on in Steam VR input binding UI for the held in hand role.

[unique plover]

Running into an issue with the packaged version of my game...runs fine in VR Preview mode, anyone have any ideas on what I could try? The right eye looks correct, but the lights are distorted in the left eye. I've tried adjusting a lot of the render settings (e.g., turning off InstancedStereo) without any luck.

[unique plover]

This is what it looks like in VR preview mode. The render issue above is actually there for both the packaged version of the game and when running in standalone.

[real needle]

Hey there folks, has anyone encountered problems using the passthrough API (on oculus quest 2) in Unreal 5 (the oculus branch from github)? following the instructions from here https://developer.oculus.com/documentation/unreal/unreal-passthrough-overview/?locale=en_GB, I can do everything except add the "Oculus Passthrough Component" to my VR pawn - the only vaguely related component that shows up for me is the similarly named "Oculus XR Passthrough Component", which doesn't seem to do the same thing (in that it doesn't have the same properties - eg the 'positioning' setting - and with it added and activated I only get black where the passthrough layer should be). Weirdly I can open other projects in which I already set up Passthrough and they build and run fine with the passthrough component that is already added to the pawn - but as in my recent project, I can't find the "Oculus Passthrough Component" in the add component dropdown. Any advice would be gratefully received! Thanks, Tim

(I'm on the oculus-5.0-v46 branch if that helps any)

[brave trellis]

Friends! Who knows how to make the same MENU but only under VR? I can't figure out how to switch between widgets in VR? Maybe someone knows the link to the video with the lesson? Or maybe someone wants to record such a video? I searched the internet but unfortunately I couldn't find anything. Help me please.

[muted scarab]

Hello All, I am in the process of migrating my game to UE5. 1st issue I have encountered is some of Oculus Touch Controller inputs not working.

I have activated Steam VR and Oculus plugins. Currently the trigger mapping (and buttons) work but thumbstick don't. I use 1st gen Rift. And tests been done in VR Preview. Any pointers would be great.
(Input listing lists both X and Right/Left for the thumbsticks I have tried both)

[distant spoke]

hey guys, i am developing a VR experience and i'm trying to display correctly scene capture 2D on the headset, so far unsuccesfully.... anyone have any idea i could i work this out ?

[muted scarab]

Can you explain a bit more in detail what you want to do?
You should be able to do it via UMG for example. Or just map it on a card.

[distant spoke]

hey ! so im experimenting with portals in VR and am trying to display scenecapture 2D correctly in VR, i figured i need two scene captures compunent per portal one for the left eye and one for the right. but i cant get the position of each eye to get the stereo image of both eyes to match up

in the shader mat of the portal i am able to display one texture per eye using a custom node with 'return ResolvedView.StereoPassIndex;' and a lerp afterwards

[unique plover]

One thing I'm probably going to do before release is move to the OpenXR plugin - I don't have any experience with it, but one of the things it provides is to "fill in" the mappings for controllers you can't test with (e.g., specify the Index inputs and it will, theoretically, map the Oculus Touch inputs as long as you haven't explicitly added them). Might be worth looking at?

I will say that using only the SteamVR plugin (I didn't install the Oculus plugin), I was able to get the Oculus Touch inputs working fine with a Quest 2. I'm not sure what differences might arise when using a first-gen Rift instead.

[sinful goblet]

Guys how can play vr in viewport instead of launching another standalone?

[dapper turtle]

hi all,
how does one account for different screen resolutions in VR? i'm using a stereo widget (from VR Expansion Plugin) and it shows in landscape mode on the quest and in portrait mode on the index. how do i dynamically figure out the draw size?
here are my current settings

[ashen dome]

Hey quick question. I made mirrors in UE4 so I could see my VR character with the planer reflection method. But Now In UE5 everytime I launch with the planer reflection plane in the VR template the editor crashes 😦 Anyone know What I need to do. or what the Issue is. Thanks.

[valid pine]

hey all trying to use vr in a project but the vr preview isn’t working

im not able to click on it

using an oculus quest 2 and i cable linked it

[tribal lintel]

make sure your oculus PC app is open and your device is connected first, then restart your project with that open

[valid pine]

I did that

But it’s not working

[tribal lintel]

make sure you activated oculus link in your headset before opening the project, and also download ODH oculus developer hub

[valid pine]

Are you sure oculus developer hub needs to be installed

[muted scarab]

thanks, all leads like this help in trouble shooting.

Turning off steam VR plugin fixed it. Now I just need to figure out why UE5 forces seem so much weaker (physics based controls are very sluggish)

hi there, i been having difficulties trying to get a driving wheel to rotate properly, when i grab one side of the wheel it works completely fine, but when grabbing the other half it rotates the opposite way, does anyone have a good solution on how to rotate a driving wheel in vr?

Probably not a good idea to migrate to 5.1 just yet

[grave wren]

Hey,
does someone know how to re-enable Opengl ES 3.1 for Android/Quest 2 on 4.27?

When I package for Quest 2 with ES 3.1 enabled, and Vulkan disabled i only get 3 dots and no game loads, if I enable Vulkan the game loads.
The reason why I want to switch is, that 8k 360 degree videos play with 20 fps on Vulkan and 72 fps on ES3.1 (Quest 2 has dedicated cores for playing media files in 8k, which works in 4.26 on ES 3.1)

Thank you

[muted scarab]

do you mean 5 in general is bad idea? I am using 5.0.3
(it looked like 5.1 because I said 5 and continues with 1st...)

[mighty carbon]

if you are building for mobile VR, yes, 5.x is kinda bad idea (if it's something super simple, maybe it's not too bad). I can't say much about PC VR but I've heard it's okay'ish for PC VR.

[grave wren]

[mighty carbon]

you can have Nanite + Lumen in PC VR with UE5.x if you happened to have 3090 🙂

and with deferred you can pretty much have all the bells and whistles as pancake games get using UE5

I don't have 3090, so I don't know for sure, but based on the experiments posted on Twitter by some UE VR devs, it works fine

btw, how is this still a thing https://forums.unrealengine.com/t/native-microphone-input-support-for-android-with-full-exposure-to-blueprints/132973/2 ?!

any solution for this issue ?

[silver brook]

Shouldn't this?

Query these assets here?

The drop down doesn't show anything other than Default and Custom

[hallow knoll]

Nanite and Lumen is not yet performant enough for VR Games, but it can be used for other purposes

[glossy jackal]

For VR projects do you guys enable "smooth frame rate" or "fixed frame rate"? What do you think is the optimal framerate setting for VR? Also do you guys use a frame rate cap?

[spiral marlin]

Is it possible to send inputs from the VR controller to a widget in a similar way as gamepad inputs are sent to wigets with setting focus

I believe I've tried it and the vr motion controllers disappeared when I set focus

[ashen dome]

Does Planer reflection NOT work in vr in UE5 its all distorted for me. But It worked in ue4.

[ember forum]

LODS based on screen size does not work for VR because of DRAMATIC different screen sizes difference for headsets

what is an alternative

didn't there used to be a distance based thing in ue4

[ember forum]

another alternative is to use ODH (oculus developer hub) which is an official tool for quest2, but I also use both myself...

[mighty carbon]

used to be.. And I was arguing with one of the Epic's devs that it has to be distance based for VR (Gear VR days)

they said nope, Fortnite isn't a VR game

[ember forum]

omg thats so ||fucked||

Yeah

There gotta be a good reason for going with screen size vs distance

[ember forum]

anyone here using openxr with Varjo aero and confirm it works with an unreal engine project?

What's the goal though?

[tiny shoal]

Heya, could anyone here help me with snapping the MotionController (the player's hand, in my case) to a certain component, for something like snapping the hand on door knobs? This is what I'm currently trying, but it just makes the controller fly up?

I'm using an Oculus Quest 2, with Link Cable, if that matters

[tiny shoal]

Actually, I created a copy of the VRPawn (I'm using the VR Template) and made it inherit from Character instead of controller, as I wanted to use smooth movement instead of teleporting, but this caused everything to move up - the camera, controllers etc) probably due to the collider of the Character actor. I've just made the character collider really small and planned to fix this later on, but maybe it has something to do with that?

[idle osprey]

@hallow knoll The VR Template fails to open at all in 5.1 on an intel Mac (by default). Is this intentional or just an oversight? Manually editing DefaultEngine.ini to turn off vr.InstancedStereo seems to work (still compiling shaders).

It's interesting that I get this error now because I didn't before with 5.0.3, 4.27, etc... I hope it's just a preview thing.

[silver maple]

Is there something special to do to enable an Unreal game to write to its Saved folder on a Quest 2? FFileHelper::SaveArrayToFile() doesn't work with a path set using FPaths::ProjectSavedDir() + TEXT("Filename"). I'm deploying the game directly from the editor if that matters.

According to their release notes yes.

Rendering Feature Parity (Experimental)
We added initial stereo support for Nanite, Lumen and Temporal Super Resolution. Currently this is only supported on PC while using the Deferred renderer.

Volumetric fog is fixed let's goooooooooooooooooo

[wind yacht]

Is it finally a safe idea to jump my 4.27 PC VR project to 5.1?

[fringe blaze]

I've been using 5.1-Preview2 and haven't had any VR-related issues.

On a week-old project though

[wheat holly]

Honestly not sure. They did just deprecate all non-OpenXR plugins in 5.1 though.

Deprecated Oculus VR and SteamVR Plugins
We deprecated the Oculus VR and SteamVR Plugins in 5.1. Use the OpenXR plugin and the appropriate OpenXR runtime for your Oculus or SteamVR projects.

Refer to the OpenXR Prerequisites documentation for more information about installing the OpenXR plugin and runtimes.

[tame forum]

So the framerate is better in 5.1 but now I get strange black shadows whenever I move

[wheat holly]

Is that just default UE? Or is Lumen / Nanite enabled?

[tame forum]

lumen, nanite VR

no raytrace

[wheat holly]

I'll let you know how mine looks like in an hour or so, still downloading everything 🥲

[tame forum]

gotcha. Yeah strange, preview didn't have these shadows. it was a just a bit slow

[wheat holly]

So only in packaged?

[tame forum]

i meant 5.1 preview 2

[wheat holly]

Ah, I see.

[tame forum]

vs 5.1 official

[spice edge]

Got it running as well, for steamvr use r.RHIThread.Enable 0

[wind yacht]

I guess I'll wait a little longer to wait and see what the overall feel is

[warped timber]

Are you using 4.27 Oculus branch or 5 with new metaXR plugin for this? I seem to have issues with the latter getting Quest Pro to be a valid android build target. Not sure if you’ve run into this?

[spice edge]

nanite and lumen in VR feels amazing, runs pretty good too

[wheat holly]

Just don't try it with the Epic sample projects though 🤣
Got a whole 2-3 FPS..

[fringe blaze]

Is there a way to exit your game and open the web browser on the Quest 2?

oof, updating project from 5.0 to 5.1 even copied the VR Template from 5.1 project's .ini over and made sure to set up proper start up map again and I just get a blank screen with three dots...

No errors in log this time

Packaged VR Template project works fine no issues

Might be a plugin issue.

[warped timber]

Having issues with new MetaXR plugin?

I have been all day

[silver brook]

What's this?

[warped timber]

https://developer.oculus.com/downloads/package/unreal-engine-5-integration

[silver brook]

@warped timber Is this just for store release or also an alternative to the recommended OpenXR Plugin?

Also looks like that hasn't updated to 5.1 yet

[silver brook]

Narrowed it down to some aspect of the config causing the black screen with three dots on quest. Broke the temp project by just copying over my Config folder. so if it isn't anything inside the DefaultEngine.ini since I replaced that already it's something in the other files...

Ah it was the Start in VR UE5 for Pico didn't need it but since Pico doesn't have their plugin updated to UE5.1 had to test for Quest and it needs it. "Facepalm"

[silver maple]

How does one make Motion Controllers work on a dedicated server? I'm using the Collab Viewer template as a basis for my pawns and logic. When I'm in the app's main menu it works fine, but as soon as I arrive on the server, my controllers are no longer detected; the Controllers are spawned but they lie clasped beneath the pawn. I tried making them replicated variables, to no avail.

Is there a good resource for understanding how to make Motion Controllers work on a dedicated server? I tried looking up unreal motion controllers multiplayer on Google but there's very little information out there and much of it seems outdated.

Can anyone else confirm terrible media playback performance on Quest 2 with UE5 and 5.1?

Hey there guys I was wondering if anyone could help me out. I am creating an augmented reality tower defence game where AI must run towards a castle the player needs to defend however the AI move to always seems to be failing when I test it on my tablet. The AI move to never fails in the editor so I am wondering where I am going wrong. I have attached a screenshot below of the AI blueprint. My AI is only spawned in when the player clicks on the screen to place the castle with a plane attached to it. The AI spawn on this plane. So far I have checked that the locations are correct and that a nav mesh is included within the scene. However I am not too sure if the nav mesh could be causing issues when packaging to android? Any help is appreciated!

[mighty carbon]

on 4090 ?

[tiny bolt]

I don't think you can attach the motionController to anything in this way. Instead have a fake hand as a child to the controller, and attach the fake hand to the object you want to snap to. Hide the motionController during the grab.

The motionController moves in the same relative space as the hmd. If you attach the motionController to anything else, it'll move relative to the new parent. Hence it pops up in the air because it's now relative to the door knob.

[hallow knoll]

Which keys are you binding to the Input Actions?

[tiny shoal]

Mhmm, I kinda found that out the hard way... Appreciate the answer anyway though!

I do have another question, though - Why is my camera randomly reset at a different height every time I play my game? Sometimes it starts waaay up like I'm a giant with tiny arms, sometimes it's at what I believe is normal, and sometimes it starts at the level's floor?

These are the tracking settings I'm currently using, but sometimes these don't change that much

https://www.reddit.com/r/unrealengine/comments/at7me4/comment/hobfwul/?utm_source=share&utm_medium=web2x&context=3 This points to a few settings when using a character (my case) but these don't seem to change much

Has anyone ran into the issue of after using a Widget Interaction component in VR, none of their motion controller inputs get sent to the game unless they minimize/maximize and click on the game window again?

I figured it out!

c++: FSlateApplication::Get().SetAllUserFocusToGameViewport();
blueprint: https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Focus/SetFocustoGameViewport/

Upon closing the menu/widget, I had to invoke this to get focus back to game viewport so that the inputs weren't being consumed by the widget

Hi, I’m using a mixed reality headset (Varjo) and I’m trying to get it so that the mixed reality seen in the headset is also visible on the desktop monitor. Right now only the 3D geometry is displayed and the “real world” MR areas are just black on the monitor. Is it possible to get the camera feed seen in the headset to also display on the monitor?

[wooden chasm]

??

[dreamy ivy]

Sorry dude, I forgot I posted that here or I would have removed it. I had cloned the VR Pawn So I could modify it but figured out it messed up the cast nodes for the hand animations, had to re do them and then it worked while also changing some project settings for the enhanced input content.

[idle osprey]

It's not really "bad". That was more of a joke. It works. I just wasn't happy with the result. But it will teach you a ton about doing this sort of thing. https://youtu.be/qBooEZnlAA4

Hello there, i making a small app for VR devices where i need to display a json-formatted string. While converting it to a text and displaying on windows works perfectly (i get the breaklines and indents), on android (Meta and Pico), my text is displayed as a single line which is not readable.
I tried replacing and adding breaklines and indents myself but it's still ugly and ruins the windows display

Does someone had to deal with this ?

[sonic lake]

Is that for debug reasons or what? You can always use a widget for that.

[maiden seal]

Well the app is meant for debugging purpose, but my ui contains a text bloc where i'd like to display my json string

[idle osprey]

I'm rebuilding my dev machine. Should I stick with VS2019 or go to 2022?

[tiny bolt]

That's probably the cases of the hmd state when setTrackingOrigin is evoked.
-hmd sits on your desk when its origin is reset, you pick up the hmd and now you're too high.
-hmd already on your head when the origin is reset, might send you into the floor, might send you to the correct height, who knows. This is different behavior between the Oculus Rift and the Vive although I haven't tested in 5.1 yet.
-hmd is not being tracked when the origin is set, then the trackers find it after you pick it up: This is probably the case where you're correctly positioned.

Anyways, the issue is mostly avoidable by not doing this on begin play. You can make a timerbyevent that repeatedly checks if the Hmd is on (being worn) and then set the origin if true (and cancel the timer).

[sonic lake]

You can just split the long text with CR to display it properly in a widget. Not sure I understand what the problem is. Can you show a screenshot?

[maiden seal]

@sonic lake This is on windows, the text is formatted as expected (don't pay attention to the red drawn line)

And this is on VR (android)

Here is my blueprint, Display Scan being my text area

[sonic lake]

@maiden seallooks like Android needs a different type of CR+LF

Did you google it?

[maiden seal]

yeah but i'm having a hard time finding something usefull as nobody try to display json but rather use it to format tables or lists...

I shall mention that i'm neither and android dev nor an Unreal Dev, so i'm a bit overwhelmed when combining both ahah, it's possible that i missed something simple

[tiny shoal]

Huh, interesting that the template actually does it the "bad" away 🤔

Anyway, I'll try out something like that - Thanks!

[silk lodge]

ping me some time about replication of controllers. It's a mess

[crimson ingot]

Does anyone know the fix to the issue i'm having.
I'm working on an AR Project for iOS, For some reason, in Development builds the camera will function, in shipping builds, the camera will not.
I've tried the basic AR Templates too and same results, I'm using Unreal Engine 5.0.3
(I've also posted this in #mobile) (Reverted back to 4.27 and this fixed the issue)

[tiny bolt]

I think it's supposed to automatically reposition you during play but I've never not had to change the logic in a new project. 🤷‍♂️

[tiny bolt]

That sounds like a permissions issue. My web app has to make an api call to ios to ask the user to use the gyro. Haven't done this in an unreal project tho...

[crimson ingot]

it's weird because it does request permission to the camera, it even shows that it's enabled but the visuals don't appear on the screen

it will only appear in development mode

[tiny bolt]

Curious if there's a template you could try that works. That issue sounds painful to debug

[glad temple]

How do you display camera video from your device to the pc monitor?

[silver maple]

Thanks but I switched to using VRExpansion, which just works out of the box. 😄

[silk lodge]

that's great

[hallow knoll]

It sounds like you don't have Guardian set up properly, that's not default behavior with SetTrackingOrigin = Floor, which is the configuration you should have for room scale VR

[tiny bolt]

For sure but I'm developing on Oculus Rift and Oculus Quest II and it works on quest and is ever inconsistent on Rift. So that's my workaround.

I do be writing some pretty gnarly workarounds tho

Is this the correct place to ask for some VR input mapping help? I can't seem to map the trigger button for Valve index, the second stage trigger. "Trigger axis" works, "Trigger touch" works, "Trigger" won't - the action will be triggered on "trigger axis" instead, even though it's not mapped. All i'm changing is the option from the top down menu.. Is there something special about this input button in particular?

[prisma sapphire]

Hey guys, does anyone know why I’m seeing two different textures on my character based on which eye lens I’m looking through in VR?

[brisk sun]

Hey guys! I'm currently running into what seems to be a known issue with Motion Controller Overlap events firing off every tick. (https://issues.unrealengine.com/issue/UE-36103). The bug report says 'Resolved' 2017 But I'm still seeing others reporting it as an issue since then, I was wondering if any of you have ran into or got past this issue.

The overlap events work as expected until I attach a component to either of the motion controller components, then the overlap Begin and overlap End gets called every tick.

[dreamy ivy]

Has anyone here had issues with Motion controllers suddenly stop tracking for the project your working on? I was in 5.1 yesterday and everything was fine. then my project detected my actual hands, not controllers and now it wont track the motion controllers of My quest 2.

Testing in a default template works as they should. but my project now has now tracking or inputs. I've been at this for two days with no luck. tried the standard stuff like checking:

• Auto receive input
• Player Spawn (I'm def possessing the spawned character)
• Deleted intermediate folder
• Only using Open XR Plugin
• Checked Enhanced Input (Don't think this would effect motion controls)
• replaced Defaulteditor.ini, Engine.ini, game.ini, input.ini with those from a default template and nothing changed.
• Checked Gamemode in project settings and world settings.
• checked OpenXR input in project settings> Plugins.

I also haven't touched the motion controller components at all.

I'm really confused and I cant progress without controllers so any help would be fantastic.
The controllers just spawn on the floor and don't move In VR preview.

Thought when righting this to check the output log, I'm getting this error and the editor hangs when opening.

Also getting this one.

going through the CPP it mentions XR_ENSURE(xrCreateActionSet(InInstance, &Info, &Handle)); on each one of the lines.

[dreamy ivy]

figured it out. Enhanced input is a damn nightmare. if your motion controllers stop tracking, make sure your Input mapping context has a new description or none at all. Dont duplicate.

[silk lodge]

good info!

is it just me or msaa looks better than tsr in vr? much sharper for sure

Hey! Does anyone have experience with Oculus/Meta API implementation? More specifically the Subscription API. I need some help on this

[mighty carbon]

I hear that VR looks as good in deferred with properly tweaked TAA

Maaaybe slightly less sharp than MSAA

But with a lot more eye candy

[daring pasture]

TAA just has too many issues in vr. FXAA looks significantly better in UE5 compared to UE4, especially with MSAA not being an option for me.

[mighty carbon]

Why is it not an option in UE5 ?

[daring pasture]

For my project it's not because I need deferred, not that it cant be used.

[mighty carbon]

What about that new fancy AA method in UE5? Has anyone tried it in VR?

I am waiting on 5.1 NvRTX fork to try DLSS2.0 in VR

[daring pasture]

Tsr? I tried it but it tanked performance for me.

[mighty carbon]

Yeah, that one

[daring pasture]

I'm not a good test case to compare though since my main level is pretty large with a ton of foliage

[daring pasture]

I'm hoping virtual shadow maps gets fixed in vr. 5.1 seems to have broken them

You right 🥲

Hmm, I'll give that a try

[left cedar]

yea atleast in vr editor it does. also tried in 5.2 same thing

[daring pasture]

I haven't used msaa since 4.24 i think. Don't even remember how it looks to compare

[left cedar]

oh dude its def sharper

u just get those weird sharp dots in some areas

[daring pasture]

I would use it if I could, but my foliage would take a massive hit

[left cedar]

ahahah yea got cha

[mighty carbon]

@left cedar have you tried NvRTX branch of UE5 ?

[left cedar]

maybe..... hahaha lets just say the 5.1 is coming and its gonna be a big one

I am wondering if RTXGI/DI + DLSS2.0 is faster than Lumen

and perhaps more scalable ?

So I'm trying to use the web browser plugin on the Oculus Quest 2 and it doesn't render anything at all, unlike windows where it does... Seems like this is a problem that has existed for a while looking at forums. Anyone try anything with this?

Or an alternative method is to just open up the browser in the quest, anyone know how to do that?

[spiral marlin]

This is probably a dumb question but what size should my UMG be for a near-fullscreen HUD that sits in front of the viewer's VR camera?

[marsh crystal]

I check back every once in a while but is there any way to render ui widgets directly to the HMD yet?

[chilly ocean]

Isn't that what Stereo Layers are?

Don't render it in the main rendering pass since that messes with anti-aliasing and whatnot

[marsh crystal]

wait i didn't know about stereo layers

[ashen thunder]

in ue 5.0.3, how to disable openXR but keep OculusVR plugin?

I would like to use the Hand Tracking features but it doesn't display the hands mesh, it only shows the two menu buttons. I have read that this is caused by OpenXR plugin and disabling that, it also disables OculusVR plugin.

[remote sandal]

Good Day,

I downloaded the "Oculus Lipsync plugin 29.0.0" and followed the instructions given in the document.

As per the documentation, I copied the the "OVRLipsync" to "UE4.27-Engine-Plugins" and also into "UE5.1-Engine-Plugins".

But when I open a project in both the versions, The plugin is throwing an error saying the plugin is compiled for different version.

I also tried to copy the plugin directly to the project folder, Still same error.

Please sort the issue for me,

Thanks,

I'm using Polygon assets for my game, but I'm replacing the textures with 256x256 copies of Quixel textures (albedo only). The Polygon assets use texture atlases for performance.

My current plan is to redo the UVs of the assets and use multiple material slots instead. Since the new textures will only be 256x256, will the performance of my game be largely unaffected?

[severe delta]

I can't find it either. I'm installing 4.27 to try making it work again. Any news?

I'm praying this feature will be restored and compatible with Oculus quest 2. I teach at USF Tampa a course called Envisioning Sustainability and we are using Gravity Sketch on the Oculus to build worlds to teach climate mitigation technologies and would much prefer to develop in Unreal. Right now we are able to create and edit on the PC and then Play on the Oculus but as you know, the intuitive way of creating "in-world" with one's hands is so much more powerful. Any ideas when we can expect VR edit back?

[marsh crystal]

I forget I keep asking about the vr editor too. Honestly I haven’t had any luck getting it working in any version of ue5. The button becomes available in 5.0.3 only when I enable th steam vr plugin and disable oculus. But that doesn’t work because my headset is oculus so I can’t even use it because the controllers don’t detect. Idk it’s just been a nightmare for me trying to use the vr editor. But it sucks because it works so well for vr development

[marsh crystal]

It’s funny I did the same thing last night. Almost debating making my levels in 4.7 and migrating them over now 🤣

[pearl hare]

Thanks!

[severe violet]

Anyone ever had this with VR when using Screen Space Global Illumination?

This is UE 5.0.3

[outer flicker]

Increasing material slots will likely increase your drawcall count. So keep an eye on that.

[mighty carbon]

Screen space effects never worked in VR

[severe violet]

Ssoo.. what kind of reflections am I seeing then?

[mighty carbon]

Dunno, but you have one eye and other eye showing different things

[severe violet]

I am using the Skylight as the scene reflection capture. So Naturally I do see the other car in the reflections but. On the Hotrod I also see the inside of the wheel reflected on the chasis of the car... weirdly enough I don't see any car reflections in the mirror of the Impala?

I am seeing similar in VR

Granted you have to turn off "Forward shading" to be able to enable it. Lumen works in VR too with UE 5.1.

[mighty carbon]

I don't have much experience with deferred 😅

[hidden crest]

It worked quite well for me with TAAU enabled. Almost gets me to the sharpness of MSAA with Forward Shading.

[untold knoll]

I have some very high quality 180 stereo images that I captured with my camera, and viewing them on my quest 2 using an image software (immerGallery) looks infinitely better than on Unreal. I have a project where I drop my images and package to my quest. The difference is night and day!

Unreal can load the 8k images fine but it just makes them look much much worse for some reason

[golden current]

Have you tried thinkering with the compression settings?

[fringe blaze]

I have a master material with 1400 instructions, but it means that I don't have to use any lights (baked or realtime) in my scene. Would this be good performance-wise?

[foggy oxide]

does anyone knows how to run a console command on an oculus quest ? (thats a game packaged as apk and installed)

[foggy oxide]

you're awesome thanks, and thanks for the link.

you wouldnt happen to have a link to profile a game while it's running on the oculus right?

(ive already searched for the ovrmetricstool )

[chilly ocean]

You enable persistent overlay on the OVRMetrics tool and it should run over your Unreal Engine game

I'm on 4.27-Oculus though

[distant hill]

Yeah I don't see it in an Epic Games build on 5.1 at least, might be specific to the Oculus branch?

I get flickering in screen space reflections in VR using UE 5.1... can you do anything to fix that?

[mighty carbon]

Don't use screen space effect in Vr @flat shoal 🥲

[flat shoal]

Aww... but it's so close! No artifacts, works in instanced stereo... it's just that little bit of occasional flickering.

[mighty carbon]

If you read Epic's Getting Started guide, you'll see that even deferred rendering isn't recommended

So all these fancy features aren't officially supported in VR

So, either live with glitches or don't use the feature

[flat shoal]

Ehh... it does? I had a call with someone from Epic a few months ago and they were adamant that we should dump forward shading and just go for deferred instead. 🤣

[mighty carbon]

Official when it's in writing

I talked to Tim Sweeney on Twitter and with Epic's engineers, about them fixing occlusion culling performance issues on Quest 2.

Nothing has been fixed since then 🤷‍♂️

So, official is in writing

[flat shoal]

Well, with nanite + lumen in VR in 5.2 this will be rendered moot (for us) anyway...

[mighty carbon]

Also Oculus Meta still advises to use forward even with PC VR

Meta knows hell a lot more about VR and optimizing for VR than Epic 😂

[flat shoal]

Hmm... input mappings have gone haywire in 5.1 compared to 4.27...

Damn, the VR template doesn't even use them... time to learn something new again, I guess!

[gusty ridge]

So Im a bit confused. If I want to target Quest headsets, is the OpenXR plugin enough or must I use the MetaXR plugin for 5.0.3? since theres no support for MetaXR in 5.1 yet

[jade kettle]

So how's VR + Nanite + Lumen in 5.1?

I tried messing around with it in the VR Template Project but I don't think it's exactly working as I'm expecting

And I'm wondering if there are any project settings I'm overlooking

[dreamy orbit]

Amazing. I am running a lot of experiments - trying to see what gives the most performance balanced with amazing looks. It does require quite a bit of power to run it smooth enough to enjoy, but the future looks fantastic.

Haha I have done a project in pico. It was a real hassle to get it to package. Once it worked it worked really well though.

[uncut needle]

Have you also tried to package an empty project with the correct sdk, ndk locations and versions?

[sullen vortex]

ndk looks to be the same as oculus quest...and crash is unknown which doesnt help

[reef willow]

Anyone know where to post about some of the features in the Architecture CollabViewer template being broken in 5.1?

[uncut needle]

It might have to do with the sdk or ndk versions you have installed in android studio. If you have a lower version still installed it can give this error.

[reef willow]

The issue was related to SetPositionInViewport() and will be fixed in next patch.

Is anyone familiar with index controller inputs? I can't seem to get any input values for features that are index controller exclusive. For instance I can't get trackpad force or grip force axis inputs even though they are present in my bindings drop down.

[frank shell]

Alright, I've figured this out and it doesn't have anything to do with VR stuff.
I'm using Enhanced Input and I wasn't aware that if you want an input to be available to enhanced input you need to bind it to some arbitrary action/axis input in the Project Settings.

Hi everyone, I have a question.

I’m working on an android VR app in 5.1 but every time I turn on Mobile Multi-View I get a fatal error when I cook that appears to be related to a shader compilation error. Anybody have experience with this and whether I might be missing a related setting that’s causing it not to work?

I feel like it was working fine in 5.0. I checked it on two projects (one just the plain VR Template) with the same results on both.

[brittle salmon]

im wondering what are the bare minimum files ue 4.27 needs to do an android build for a vr headset

edit: after installing stuff as per ue documentation (every single step), apparently you only need the SDK, jre and NDK folders, which you can find from Local/Android and the android studio installation folders, and then you can copy those into one place and remove the rest of the things you installed.

the guide says to install everything through android studio, but does it need studio itself or just the sdk, ndk and a path to jdk?

my client has a strict firewall and they dont seem too happy to dig through all the addresses the studio installer uses, so they want just the necessary files

i'll tinker around and post an answer to myself if i figure it out 😅 , but if anyone knows it would help a lot

---

Which would make sense, however.. I have Android SDK 33 installed. 29 is set as my min SDK and my target SDK in project settings per Oculus documentation.

I have android 33.0.1 SDK Build tools, NDK 25.1.8937393, and CMake 3.22.1

It only just broke with my update, and I haven't changed my SDK/NDK path. I ran SetupAndroid.bat as well and restarted my computer several times but it still sees it as 29 in the engine.

[brittle salmon]

call "%SDKMANAGER%" "platform-tools" "platforms;android-28" "build-tools;28.0.3" "cmake;3.10.2.4988404" "ndk;21.4.7075529"

does the setupandroid bat have the arguments as version 29

for you

[red oxide]

Thanks, one sec I’m restarting my engine and I’ll confirm

[brittle salmon]

to me the setupandroid seems like redundancy, or i'm just completely missing something

[red oxide]

This might be the issue - in SetupAndroid.bat we run this SET command

--

SET PLATFORMS_VERSION=%1 SET BUILDTOOLS_VERSION=%2 SET CMAKE_VERSION=%3 SET NDK_VERSION=%4

But since the build tools have now gone into the 30's I don't think it's setting it correctly. It's capping at 29.

Right? Looks like it's just appending the correct number to the '2' prefix

Whereas we need a different prefix

It does also have this though (after)

rem hardcoded versions for compatibility with non-Turnkey manual running if "%PLATFORMS_VERSION%" == "" SET PLATFORMS_VERSION=android-32 if "%BUILDTOOLS_VERSION%" == "" SET BUILDTOOLS_VERSION=30.0.3 if "%CMAKE_VERSION%" == "" SET CMAKE_VERSION=3.10.2.4988404 if "%NDK_VERSION%" == "" SET NDK_VERSION=25.1.8937393

[brittle salmon]

i mean the %SDKMANAGER% seems to take whatever packages you want as arguments, so you could just replace them with the versions you need

when its called

[red oxide]

Hmm… I think I’m a little lost here actually.

[sterile sandal]

Hello, Does anyone tried Metahumans on quest2 / quest pro ?
How it looks?

[red oxide]

They're ok. It's better with TSAA on (I think) instead of MSAA but it's expensive.

[sterile sandal]

ok. Are there any apps on the Meta store which are using Metahumans?

[red oxide]

Probably on App Lab

[brittle salmon]

figured out my problem, added a solution as an edit

[jade kettle]

My company is looking into the Vive Focus 3 for our next productions, does anyone have experience with that with UE?

[brittle salmon]

i do

[jade kettle]

What SDK is that? Vive Wave?

I've also read that you can't access the pass-through camera imagery

[brittle salmon]

OpenXR, OpenXREyeTracker, OpenXRHandTracking, WaveOpenXR

waveopenxr basically

those are all the plugins you need to build for it

i havent done a build for it for a while though

[jade kettle]

Alright, because we're currently using Vive Pros but that's practically a complete different ecosystem right?

[brittle salmon]

it is

its pretty similar to quest, but you need to do some focus specific stuff

there are some resources on the vive developer forums

[jade kettle]

Thanks, yeah I was tripping over the Vive branding

[brittle salmon]

yeah, its a standalone android headset instead of a pcvr one

[jade kettle]

And little to no relation to SteamVR

[brittle salmon]

yeah actually you need to disable steamvr and other desktop vr stuff once you do a build for it

in unreal editor plugins

[jade kettle]

Yep

Argh now I do remember I did an experience with it in Paris with it connected to a VR Backpack and it was using SteamVR

[brittle salmon]

yeah it can connect to a pc too, probably was doing that then

it has a wireless streaming app built in too

[jade kettle]

So that's an option

Oh it does?

[brittle salmon]

it does

[jade kettle]

Wireless to PCVR?

[brittle salmon]

yes

it needs the vive business streaming app on pc to stream to it

[jade kettle]

Ah, more expenses 😅

[brittle salmon]

its free

despite the name

[jade kettle]

(This is the Paris VR experience I did https://www.eternellenotredame.com/en)

[brittle salmon]

nice, im under an nda 😅

[jade kettle]

Hah I can imagine, the Vive Focus 3 is not really consumer level

But thanks for answering!

One last question, the map sharing function, is it easy and stable to work with or is it a nightmare?

[brittle salmon]

just to save a bit of time for you, you'll need android sdk build tools version 29.0.2, and ndk version 21.1.6352462 for the focus 3, once you start installing the android studio stuff

[jade kettle]

if you've worked with it

[brittle salmon]

i havent heard of that

[jade kettle]

https://forum.htc.com/topic/12744-map-sharing-lbe-features/

https://www.youtube.com/watch?v=Nwj5hkg35dQ

It's pretty cool, I was in the same space as around 30 other people and I was able to see their representations very accurately

[brittle salmon]

yeah i haven't done anything like that with it

[jade kettle]

Like even hi five my colleagues while wearign the headset

Which is why we're looking into it

[red oxide]

Did a fresh install of the engine as well as android & all it's accompanying tools per the Epic instructions and I'm still getting nowhere 😦

[odd shadow]

Had someone same problem with AR session config in UE5?

[brittle salmon]

you only really need a sdk, ndk and jre to get it working, the unreal instructions makes you get the wrong versions

i'd try installing the right sdk version in android studio so it matches whatever quest needs, and see if it works

and not use the .bat since it downloads some old versions and sets them as the sdk

the .bat sets the windows environment variables, which is what unreal uses as a backup if you dont manually specify a sdk or ndk path in the editor

idk if android studio updates those if you install a new sdk version

[subtle raft]

Whenever I use this node the engine crashes (5.1) does this happen for anyone else? I have a feeling this might be a Quest Pro exclusive issue

[quick dirge]

Don't know, but this node was implemented for OpenXR in 5.1 (before that, it just wasn't working at all), so new feature + new headset might be an unlucky combo. If that's any help, I think I posted a workaround on the forums to basically implement the same thing with just a few BP nodes.

[subtle raft]

What video card do you recommend to program things in virtual reality? I have a 6600xt and its performance is fatal

Hello group! I have a problem that I can't create the APK, when I try to do it I get the message "SDK NOT SETUP", I've tried everything and everything looking in Unreal forums, Unreal Discord and hours of videos in English, but no solution to this. I want to export to create the APK for my Meta Quest 2.

[real needle]

Hi
Can multiple vr headset be used in one game??🙄 ue5.1

[tribal lintel]

That button is there to detect if your thumb resting is on it, to drive hand poses. If I remember correctly it's just a true or false so it's not actually under input, so you would use their BP or C++ function to check for it from the oculus plugin. most likely requires their source build or their new standalone plugin

[tribal lintel]

yes

[real needle]

Can u give me doc or help??🙄 its very important for me 🤦🏻‍♂️

[maiden willow]

This isn't VR specific but it will give you all you need to know in order to understand the fundamentals for replication within Unreal Engine 5. It won't matter if you build the game as VR, 3rd person or even 1st person - it all works the same at that point.

hey, everyone. Has any one had an issue with 5.1 were the oculus app opens in a window and is saying it's missing the OpenXRHMD Module? First time it's happened and I'm a a bit thrown.

I can successfully build the APK, and get it onto the headset but opening it just creates a window which then closes the app.

[tribal lintel]

are you using 5.1 launcher? have you downloaded the new meta standalone plugin that is the replacement for their oculus source branch?

[dreamy ivy]

I am and I have, the plugin wouldn't load saying it was missing some additions.

I only needed to enable it temporarily for testing so I used the old deprecated plugin in ue5.1 but if there's a way of making the metaxr plugin work with out source I'd live to know.

[distant hill]

I haven't been able to get the MetaXR plugin working but the regular OpenXR one works just fine

[keen prawn]

whats like default setup for VR these days? used to be forward shading and instanced stereo and stuff like that... but now with UE5 and FSR 2.x anything changed?

The way I instantiate and use it works great on Windows and Mac builds

VoiceCapture = FVoiceModule::Get().CreateVoiceCapture(CurrentDeviceName, 16000, 1);

Which gives me a TSharedPtr that I store on my ActorComponent which is on the main player Character

Something bizarre I've noticed is that I'm getting supposedly 268435456 bytes of audio data... at once... which is insane because that's 268 MB. Actually, looks like I'm just hitting some kind of maximum there lol. And then the encoder can't encode any of it, so seems like it's invalid data.
And again - the entire implementation works great on Windows and Mac.

Hey guys, does anyone know if Google ARCore face augmentation detection works with UE5?
The last reference I could get of it was from a tutorial made with version 4.26 that used the GoogleARCoreFaceMeshComponent to work. But that component is marked as deprecated in UE5 and I can't see it in the Blueprint Components drop down either.
Apart from that, it seems like ARFaceComponent is the new way to go forward, but I can't seem to find a way to make that work? Does anyone know how to get face detection to work with ARCore?

I ended up writing some platform specific code and directly using the "GoogleOboe" module that underlies the Android implementation of AudioCapture. (which is hardcoded to 2 channels of floating point data at 48khz... so i couldn't use that sadly) But using Oboe directly works great.

Update: turning off texture and level streaming fixes the freezing!

[winged gorge]

If you have your vr headset connected to your pc it should work automatically. If you have steamVR or Oculus home started up it will work.

In the camera settings of your player character, make sure this box is checked (It should be by default)

And in the project settings, tick this box (this is for when you make builds, wont change anything in editor)

[zinc violet]

@worthy quest@ashen thunder not sure if this was mentioned already but current Oculus runtime doesn't anymore do editor check for Quest handtracking.. so it can technically work on PCVR runtime. I haven't tried this on Unreal but at least on Unity you can just read the hand tracking data from OpenXR extension. Microsoft has XR toolkit that implements this API for handtracking (and they have this SDK for both Unreal and Unity).

There isn't anything Unreal or Unity specific here, only mentioned this because I've only verified this data to be available on Unity's standalone builds through OpenXR api itself

Looks like what comes in the template isn't what is accessible through the dropdown for some reason.

i changed the VRtemplate folder location and did some modification to the blueprints. now i cannot rapidly shoot balls but only when the previous ball disappears and after i select an option in the ingame menu i can no longer move and interact using the controllers. where could i look for a solution?

[uneven python]

found something more about the problem. it seems that when using the menu and clicking on it, UE looses focus of the game window. if i left click with the actual mouse, things start working again, till i use the menu with the vr controllers

[sturdy coral]

It's a known bug in the widget interactor in 5.1, I think you can find a pull request fixing it on github

[uneven python]

but it does not happen in the original vrtemplate. what changed when i modified it?

@sturdy coral

[sturdy coral]

Oh wait, sounds a bit different

There is one where widget interaction sets focus of the real slate user instead of the virtual slate user to the widget

That may remove window focus too I guess, but I'm not sure. It makes motion controller presses stop working though since they try to get routed to the virtual window instead of the main window -> viewport -> player controller

[sturdy coral]

Did you change anything in the ui blueprints? If they didn't capture focus before it may not have happened

[uneven python]

if by the ui blueprints you mean the ingame menu with: reset,restart,qui then yes i did

I have 8 level in project and should switch level to level in same reality space and 5 players should be switched to the next level at the same time.

what is the best level switch way to do this?

I put the two levels in to the one level for try..!

[jade kettle]

I specifically work with the Vive Focus 3, but I'm guessing this might be applicable to other standalone headsets. Lots of these headsets have device specific features, but if I wanted to use it mainly in the context of PCVR, can I still get access to these features?

For example, hand tracking, does that work with a PCVR package or do I have to specifically make a device specific package to be installed on the headset

[candid cape]

Anyone know how to fix this?

This is a nanite scene with lumen

I tried 5.1 and 5.2 but it didn’t fix the issue

Does anyone have the proper export settings for Quest 2 in 5.1? I’ve been trying everything I can find online, but keep having issues (mainly an extremely red saturation after installing the apk).

[deep pike]

What would be the best practice for faster debugging on iOS devices? Right now I'm developing on my workstation with a 7700K iMac 2017 for remote building + 2017 iPad Pro for deployment. A very simple ARKit scene took ~2min to deploy and test.

Wondering how much time would it save if I upgrade to iPad Pro 2022 M2 + M1 Mac Mini? Or any other practices for faster testing on iOS devices. Thanks

[pseudo tusk]

Hey guys, what UE5 features would it be reasonable to have in a VR game supposed to run on Quest 2?

[pseudo tusk]

I'm more about which are the ones to not have. I'm guessing Nanite will be out of the question, what about Lumen?

Okay, anything else?

I never used UE4 really, so I'm not sure what to disable or enable for VR

Okay, so no Nanite, use forward rendering, Lumen is outta the window, otherwise work as normal, got it

I wonder if this stuff could work using PCVR

I mean, Lumen and stuff should work with PCVR, right?

Nanite might be a problem - is there a way to un-nanite a mesh depending on the user's settings?

Oh god I just realized I'm gonna have to use LOD... oh my god

[pseudo tusk]

I don't think that Quest 2 supports DX12, and that even if it did, it wouldn't be powerful enough to support Nanite

[gritty yew]

anyone know of a specific reason that a normal character HMD would control it's camera, but when possessing a pawn in a multiplayer game, the HMD stop controlling the camera? it is trying to move the camera, but the view stays the same no matter what. only way i can rotat view is with the controller rotation.

when i play normal standalone, works fine, when i possess the pawn in the multiplayer server as client, it sets the camera at floor and i can no longer control camera rotation with the HMD

i just can't wrap my head around, why it works fine in standalone, but when i join server as client, i can't controll the camera anymore...

[atomic drum]

This is probably been asked a billion times. Can anyone tell me how to set the forward direction of the HMD so I can orientate it to match the Player Start?

[pulsar fox]

Hello! Has anyone using hand tracking in 5.0 had Oculus System Gestures not working? I cannot open Oculus Menu with classic pinch while using hand tracking and i cannot figure out why

[silver brook]

Anyone here ever tried to make or is making or perhaps just have an opinion on fast paced VR games that involve wall running, jumping and just heavy on movement mechanics in general?

[wheat holly]

If you just want an opinion, it doesn't really matter too much. Some will dislike it because they can't play the game because of it, others will love you for it. But in the end it comes down to how well it works and how good the game is.

Stride had great success with it because it was fun to slide around, jump and what not but it was also mixed with some other fun stuff. Although I personally never bought the game because they went mostly a PvP / multiplayer way at some point. Can't be bothered by that 😛

But the biggest downside to it in specific is probably that new VR players will stay far away from your game. My brother recently got a headset and we haven't played anything yet that doesn't involve teleport locomotion for him. But again, some of the most played VR games are an absolute disaster for new VR players but they instead focused on making their game great and were able to do so because of those choices.

[silver brook]

@wheat holly Seems reasonable, I guess there are two perspective, make what you love and those who see it how you see it will gravitate to it and make something to target as many people as possible.

[hasty smelt]

Has anyone figured out a way to use hand tracking over Airlink yet? I have see a few mentions of OpenXR now being able to do it, but no confirmation.

[idle marten]

YES

[idle marten]

yeessss

use the OculusVR plugin, in the project settings.. change the OculusVr Api to Legacy.. also.. in the Oculus app.. you need to go to settings->beta->enable runtime features.. and enable it

ill link the video tutorial i found on this
https://www.youtube.com/watch?v=BdY8eGCwexQ&list=PLbgD2Tk2QUnkYVdDN-EMSiinyKpWXRpIR&index=14

[slim estuary]

Unfortunately this still does not work over Airlink when you package for Windows... it only works in the editor. Hopefully they will allow us to use hand tracking over Airlink one day before the Quest 2 is obsolete. Virtual Desktop is able to do it, so it is possible.

[idle marten]

ooohh

gotchya.. you're packaging a windows app

i thought you were asking about testing a quest app in editor with airlink

[slim estuary]

Yeah, hand tracking has always worked fine in the native headset... but going over Airlink has never worked outside the editor. Shame Epic refuses to give us this very simple option as Virtual Desktop can do it.

how to reset world origin rotation on HoloLens2 in UE5.1?

[dire citrus]

Hey! I'm currently encountering a problem with a VR project : Shadows are show only in left eye
-I have 1 directionnal light movable
-If i disable instanced stereo Right eye is full glitchy
Any ideas to fix it? Thanks! 😁

[woven dragon]

I just started trying out lumen and my new character pipeline in VR last night and the first most noticeable issue is the grooms only rendering in the left eye. This is with a Vive 2 Pro. Also some glitchy shadows overall.

[woven dragon]

Yeah shadows are super glitchy in both eyes. I tried using "-norhithread" as suggested here but it didn't help: https://www.youtube.com/watch?v=L8t_pOjYVz4&ab_channel=iBrews

[woven dragon]

I increased the shadow scalability to High and that fixed the flicker, but introduced some stutter, particularly around the outside edge of the viewport. Cannot see it in the preview window but for sure in the headset. This is Vive Pro 2 and 4090.

Side note, I recommend turning off SteamVR Home in the settings, it was eating up 5GB of VRAM

[silver brook]

Only thing that comes to mind is him being on a 3080 mobile. Also these features are still experimental for VR.

[woven dragon]

I was able to resolve it by increasing the shadows to High but again that introduced stuttering

Without the groom its a moot point, the shadows still look like crap at the moment, maybe by 5.2 it will be better 🙂

[silver brook]

Hence the experimental part

Yeah hope they keep working on it

Will be exciting

[real needle]

I'm having a hard time making the microphone of the Quest 2 work on our game.

DefaultPlatformService=Oculus
bHasVoiceEnabled=true

And with that when I use Create Audio Capture it always fails with "Error: Failed to open oboe capture stream: ErrorInternal"

Anyone got an idea of what I'm missing ?
Edit: the solution was to ask for permission on android

[vocal crater]

Apparently it was epics decision 4.27 works fine. 5.0 kinda breaks slightly and as of 5.1 with the new ik full solvers it completely breaks the vr body set ups. Cannot do it with out plug ins. I’ve tried but I’ve already upgraded don’t wanna go backwards so just hands will have to do for now

seems like they could have left the legacy solver in place until there was a new 1st party implementation :/

[unkempt steppe]

How would i make frame rate visible in VR?

[sonic lake]

The engine FPS or the HMD frame rate? The latter is available through the debug HUD of each device. The former can be easily displayed in VR using a Text Render component and having it show 1/Delta Time

You can also do stat fps but it is not very visible

[clever forum]

i have been trying for the idk how long to make vr hands that have physics. basically i want the end result to be vr hands that dont pass through walls and can push stuff like small cubes. but i have no idea how to do this.
i tried using this BP to constraint a phys constraint to the motion controller to the "left hand collision" which will just be my virtual hand. doesnt work, any idea on how i should do this?

[vocal crater]

The crazy part is you can use the old mannequin as a work around right…. But once you enable the openxr plugin the camera refuses to attach the skeleton because of the vr height and rotation set ups so the vr origin node is one reason its breaking so as of now the camera never stays where you place it you can attach it. Get a scene component set the transforms and the camera will never ever ever attach to the skeleton or act accordingly in vr once you disable the plug in, and uncheck the hmd , it acts like first person or third person cams again I’ve tried everything . No dice… the messed up part about all of this is the 4.6 and 4.7 meta vr plug in for unity and the open xr plug in for unity both support full body avatars ….. I’m highly disappointed I really looked forward to it but I guess until then I could just keep my project going until solution arises.

[jade kettle]

Is there a way to unlock FPS in the VR template? Right now I'm testing performance but it's either 45FPS or 90FPS

[sonic lake]

@jade kettlethat's how VR works, the FPS is locked to match what the HMD is requesting. What you can actually do is test the performance using the own HMD performance monitor. That provides the best metrics about the real user experience.

[jade kettle]

Ok thanks!

I've got the performance graph in SteamVR, but is there a more indepth performance monitor?

[sonic lake]

@jade kettletypically each HMD has an own performance monitor. I am familiar with the Oculus one.

For good metrics you want to get as close as possible to the device.

You're looking for vr.PixelDensity if you're in a more recent version of Unreal Engine.

[radiant sundial]

is changing world scale a good way to deal with people of different heights? for example i'm 6', so 100% world scale is being built for my height, so if someone sets there height as 5', should i set world scale to somewhere around 80% for them? secondly is there any resources/tables for good world scales for people's height?

[sonic lake]

@radiant sundialthat's not usual nor ideal, unless you have a particular use case for it. We all see the same world from our own respective heights and this is what you want to make for a natural feeling. The world is always the same regardless of your height.

In other words, you don't scale the world to match the player's height, you just ensure that they can perceive the same world from a vintage point which is as close as possible to their real height.

Plus you need to cater for seated vs. standing experience.

[radiant sundial]

well the problem is the height the models is built is for 6' player, i would basically need to scale these down for someone smaller.

and only along the z axis ideally.

[sonic lake]

Ok this is a different need. You have an avatar and you want to make sure it is proportioned for different player heights.

[radiant sundial]

yes

[sonic lake]

There are various possible approaches depending if they can see themselves in mirror like surfaces or only look down at their own bodies

If they can see themselves reflected you need to avoid distortion, so you may need different avatars, pre-scaled for different height ranges

Or scale the avatar at runtime to match the height

This in general works fine expect for the physics/collisions

[radiant sundial]

yes, i could probably scale easily. there are no mirrors to worry about for my game.

[sonic lake]

ok so that could be a good approach

but don't scale the world

[radiant sundial]

ok, thanks for the advice.

[real needle]

Would someone kindly tell me how the HTC Vive is supposed to run in UE5.1 without SteamVR? Everyone tells me to use openXR, but what exactly is that? I have activated the OpenXR plugins in UE, but what else? I can't even use VR preview because it's greyed out. Anyone?

How am I even supposed to set up the vive without SteamVR?

So I guess the application SteamVR is still needed, but I have to disable the SteamVR plugin in UE and use OpenXR plugin instead?

[wheat holly]

but what exactly is that?
OpenXR is a way to interact with devices through an open source standardized system. Before OpenXR all platforms had their own systems. Steam had (has) their own API, Oculus/Meta had (has) their own API's and when a new headset comes out they have their own stuff as well. OpenXR aims at removing the need to constantly have to update software to support a certain headset and instead relies on those device manufacturers to support OpenXR and 'just make it work' from the perspective of a game developer.

The Steam, Oculus/Meta and Windows Mixed Reality plugins were deprecated in UE5 in favor of OpenXR.

I don't exactly know how it works with the Vive though. But so far OpenXR is far from perfect if you ask me.

• Users need to define their own OpenXR runtime in menus no one ever goes to. It does get a default assigned though, but sometimes this causes issues when having both Oculus/Meta and SteamVR headsets. Or previously used one of both.
• Not everything that was previously there is still implemented because it's rather new.
• No 32 bit support so far on Steam's platform (I personally couldn't care any less, but is a deal breaker for some).

[real needle]

That sounds like I should keep using Steam VR plugin until it doesn't work anymore.

[wheat holly]

Having worked on a Unity game that ported to OpenXR, I wouldn't recommend it so far. The old stuff works just fine and may not be an ideal situation for new headsets but OpenXR just isn't either. The idea is wonderful of OpenXR but it needs more time IMO.

Yes I'm aware this is the Unreal Discord. 😛

[real needle]

Doesn't matter to me. I just need VR to look at projects in VR preview, I don't even export them. I just need the VR preview to work.

Looking around and teleporting is all I need.

[wheat holly]

Not sure why it's disabled though. Regardless of which one you use it should still have the preview.

[real needle]

I have reinstalled and set up SteamVR and the preview is working now, so that's solved. I've already run into other issues by now, but at least VR preview is working again. Thanks for replying.

[zinc violet]

bit old message but I mentioned earlier here already that Meta did remove the editor checks few versions ago from oculus runtime. Actual UE and Unity integrations probably have those checks still in place but you can read the hand data from OpenXR extension directly and it works, even at runtime on packaged PCVR build. Virtual Desktop is different, afaik they actually run the hand tracking on Quest app side, which was never restricted.

see #virtual-reality message

I don't know if they plan to keep it this way in the future, afaik it wasn't officially announced but happened around same time when they added eye and face tracking settings for Quest Pro's PCVR access

Hi I have made a basic VR Pawn using C++ but when I load into the simulation it doesn't track my height properly and I am really low to the floor is there any way to sort this?

[wheat holly]

Try adding this node to your begin play. (Don't remember what the C++ variant is, also won't really matter anyway I guess). Should fix any weird offsets. Do note that if your pawn's origin is at the zero mark and you use player starts it will still be too high, I usually just move the player start half way in the ground.

[slate frigate]

okay thank you

I will give it a try

[wheat holly]

In at least 4.27.2 I have both the X and Y in the input settings for the trackpad. Not sure.

Are you using an older / newer engine version? The new input system?

[tame forum]

yeah, new system 5.1

[wheat holly]

Perfect example of OpenXR being weird. I just enabled it to see how it was right now and SteamVR was the main runtime on my PC. When I wanted to use Airlink with my Quest it greyed out the launch in VR button because it required the Oculus/Meta runtime 😅

I hate both versions so much, non-openxr is just so much more stable, but openxr provides some really nice stuff like actual proper hand rotations based on the device playing instead of manually having to mess with those things... :/

[tame forum]

[wheat holly]

Create a regular pawn, attach a camera to it and make sure to launch it in the VR preview. Perhaps that you also need to enable "Launch in VR" in the project settings. Then set that pawn in your gamemode to be the default and that should be it.

To my knowledge console stuff is usually under a NDA, not sure if you're going to get an answer here honestly 😅

That's great Will give it a try and will update you

Thank you

Any Tutorial on how to install basic wasd movement on my VRPawn instead of teleporting? Or using the thumbsticks for walking? All I can find is for Unreal 4 and it works differently in UE5.1. The blueprints are different, so the UE4 Tutorials are useless.

[jade kettle]

Yeah it's weird. You can activate it to use Meta runtime somewhere in the Meta Quest Desktop app settings. But yeah, I thought OpenXR would auto-negotiate which headset and platform it would use but it doesn't

Granted, we are probably in the 1% who switch between platforms

How I understand OpenXR, it now works as the following

              _Action_            _Actions translated to target runtime_
Unreal Engine ---------> OpenXR ----------------------------------------> VR Runtime (e.g. SteamVR)

where it used to work as

              _Action_         
Unreal Engine --------> VR Runtime (e.g. SteamVR)

With the latter having the drawback that the action would work on a SteamVR headset, but not on a Meta headset

[wheat holly]

I don't really care that I have to do it, but the game I used to work on had issues with this that people who previously had either a SteamVR specific headset or a Meta headset bought a new headset from the opposite stuff and had their setups wrong which sometimes would cause issues within the game. By far the biggest flaw of OpenXR if you ask me that this kind of stuff can happen.

And because most people have absolutely zero clue how that works the best case scenario is that they found the Discord for it or made a forum post. Worst case they just refunded 'because the game didn't work'.

[jade kettle]

Ai that sucks

So basically what was happening, if the user switched from SteamVR to Meta, was OpenXR sending SteamVR specific data rather than Meta

Without a clear indiciation that this was happening

Because the OpenXR set-up was still set to target SteamVR

[wheat holly]

For example, or the other way around. And nothing warns the user about perhaps having the wrong selected runtime yup.

We also had cases where the entire runtime would not load and boot up in a PC mode instead.. But I'm not sure where that came from so I'm not necessarily blaming that one on OpenXR 😛

[jade kettle]

Yeah, my company wants to update and transition away from our Vive Pros so I've been checking out the Vive Focus 3 so this week has been filled with that

There are several SDKs for it but they're all specific to a certain use case

[wheat holly]

The wonderful world of VR 😄

[jade kettle]

e.g. one specific SDK is for standalone app on the headset itself, the PCVR implementation uses OpenXR, there's also an OpenXR SDK for standalone

And each one doesn't have the same amount of supported features and the documentation is rather vague on it

Yep haha

Sorry had to rant about that a bit

[wheat holly]

Neh all fine, I think every developer that had to deal with this is frustrated about it. There's currently just no simple solution that "just works". Hopefully OpenXR improves things over time and companies stick to it but it's definitely not too great atm.

[real needle]

Anyone have an idea how to setup simple wasd movement while in VR preview?

I'm talking about moving with wasd (or thumbsticks) instead of teleporting. Using the HMD only to look around.

[jade kettle]

Just add those inputs and transforms to your VR pawn? You'll probably need to finagle with it a bit

[real needle]

I'll gladly create a blueprint and add it to my VRpawn but I need a tutorial on how to create such a blueprint in the first place in UE5. I can't even look up how they did it in the FPS template because I don't know where to find the input related blueprint.
Actually I think I'll go back to 4.27 for my simple tasks, UE5 has given me nothing but trouble so far. UE was always hard on beginners, but with 5 it went completely through the roof.

[marsh lily]

i need some help i can't get vr locomotion to work?

[quiet swan]

is there any like early release programs for oculus quest?

like how test flight for apple or google play console for andriod?

[cedar spindle]

It would be so cool to have my music in a VR/AR game. If anybody is going to finish a project I can write music for it just to get a foot in

[sonic lake]

Break it down into simple steps. What is the first thing that doesn’t work or that you need to implement?

[jade kettle]

EVERYTHING

[sonic lake]

That’s a good start 😉

I forgot to tag @marsh lily

We are talking about VR locomotion

[zinc violet]

is there some specific reason to use 5.1 for Quest 2 dev now?

also as a side note, last "fully featured" custom branch from Meta was for 4.27, with all their goodies

like AppSW, late latching and tonemap subpasses

[pearl lava]

Has anyone tried using Lumen in VR with the HDRI plugin?

This gives me a huge performance boost. (well almost)

Here is how that looks like.
The black glitches appear in the direction of head rotation.

Looking around very slowly doesn't have those glitches and they only appear in VR, not in the editor.

[tribal lintel]

all of that is coming to 5.1, instead of using their fork of unreal, they are moving everything to the standalone plugin for ue5. currently no there is no specific reason, it depends what exactly you need, you will have to compare the current state of the 4.27 fork, and the plugin. At this time their 4.27 branch is probably their most full featured unreal product currently, and is most likely still the best bet for shipping

[marsh lily]

@sonic lake hi i tried this i can't get it to work

[sonic lake]

Ok. Does your Pawn have any movement component?

In other words, what does your pawn look like in terms of hierarchy of components?

[hallow knoll]

Linking Enhanced Input/OpenXR related conversation from #enhanced-input-system as it may be relevant to ya'll: #enhanced-input-system message

[marsh lily]

i'm using a character and it has character movement is that it

[sonic lake]

Ok. Next thing to check is that the input events are working properly. You can place a Print String after each event to write a message to the log file. Did you do that?

You can click the inputs while previewing in VR and check the log file afterwards.

[marsh lily]

yeah i did that but nothing came up in the logs

[sonic lake]

Which means your input events are not being triggered. Victor has posted above a link related to the use of inputs in VR.

You may also want to check how inputs are handled inside the standard VR template.

[marsh lily]

ok thanks for your help and sorry i'm new to this

[sonic lake]

Nothing to be sorry about. You have learned some debugging skills which may be useful going forward.

[thorn flare]

Hey, i'm trying to get a game working with the oculus online subsystem, but it immediatly crashes on Quest unless google play's online subsystem is enabled, what do i do here?

[rocky nexus]

did you set oculus as subsystem to use? afaik google one is the default. its in .ini somewhere

[thorn flare]

Oculus subsystem is on and it's default in ini

[rocky nexus]

in androidengine.ini as well? if it crashes something wants it to be there, perhaps you are using something that depends on it by accident? got to check stacktrace to see exactly where it fails. running with debugger might also be useful, if quite annoying to do

[thorn flare]

based on what i've deduced, it's crashing because of something called androidplatformmisc.h

that being said, i'm new to this and i dont know how to exclude it from being in the packaged build

[thorn flare]

I dunno how to fix this, it should be easy to disclude androidplatformmisc.h from my package

I keep seeing people saying they included it but I dunno how to even remove it?

[stone lark]

Can anyone enlighten me on how motion controller MotionSource is used in 5.1? Specifically, in the VR Template the VRPawn has motion controllers set to "Left" and "Right" as I'm used to, but in the Menu class it's checking for "LeftAim" and/or "RightAim" to set a ref to the pointer hand. So presumably MotionSource is changed at runtime but I can't find where.

[cerulean wigeon]

this is just off the top of my head, but i believe the pawn has another motion controller component that has the source set to aim

[stone lark]

ahah you're right, should have noticed that, thanks a lot!

Could you explain the underlying concept here? Does the WidgetInteractionComponent require the 'aim' motion source or something?

[cerulean wigeon]

doesn't require it, but it has a different transform to better align the WIC as opposed to the transform for the grip

[stone lark]

got it, I see it's also used for aiming the teleport target, makes sense, thanks very much

[zinc violet]

any source for this? asking because would be surprised if they managed to make AppSW work as plugin

they didn't even manage to make that work for 5.0 or 5.1 on their custom branches

and yes 5.1 has custom branch from Meta too

(although it's marked preview atm: https://github.com/Oculus-VR/UnrealEngine/tree/oculus-5.1-preview)

[tribal lintel]

hmm I remember testing and using spacewarp, I thought it was for 5.0, but maybe it was their 4.27 branch

https://developer.oculus.com/documentation/unreal/unreal-quick-start-guide-quest/

here, their landing page for new developers, they direct users to use the plugin for both ue4 and ue5, while here:

https://developer.oculus.com/documentation/unreal/unreal-gsg-quest-quickstart/

they list it as a second option

https://developer.oculus.com/downloads/package/unreal-engine-5-integration/

late latching
Application SpaceWarp
mobile tonemap subpasses```

[silk lava]

Agree having issues getting any information, and becuase the docs are so bad, there is also no tut's online for it.

[sonic fjord]

oculus UE got messed up ever since the move to openXR. I really hope they're able to actually move everything back into a plugin that updates in lockstep with mainline UE, instead of having a source build that's 2 versions behind. without source builds, it's not even at parity with the pre-openXR plugin.

[quiet swan]

Does the oculus have any early release programs like TestFlight or Google play console?

[sonic fjord]

Quest apps can be Early Access. You can also use App Lab, which has less stringent requirements for release.
Failing that, SideQuest is the last option, but everyone using your app has to set up Oculus Developer Mode.

[hallow knoll]

They're working on making the MetaXR plugin have feature parity w. OculusVR: https://www.unrealengine.com/marketplace/en-US/product/8313d8d7e7cf4e03a33e79eb757bccba/questions

The goal is to reduce the need for the Oculus fork, so that you can work and ship w. Vanilla UE

[sonic turtle]

Does anyone know equivalent of UOculusFunctionLibrary::GetDeviceType() in OpenXR? I want to check if the player device is Oculus Quest, Rift or something else(not vr).

c++

[quasi goblet]

Does anyone know how to solve this to be able to build for oculus quest 2 on ue5. Went through every tutorial. Have visual studio, android, every sdk, everything tutorials said linked up, restarted multiple times, nothing works. What is this circle of hell

If noone figured this one out are you even building projects in unreal5. Do lower versions have this issue?

this is my android setup... maybe if anyone has it working they can check if some of this is checked or unchecked for them

[sonic fjord]

in 4.25, I had to uninstall Android 13 to get it to build lol. but if I recall correctly, 5.1 was working without doing that

If I'm looking to create a low-poly game with high performance at high player counts in mind, would Unity or Unreal Engine be the best choice?

I remember hearing that Unity has better general performance, but after doing some looking around, the answer doesn't seem so simple.

[quasi goblet]

is it possible to package a game for vr for oculus quest in 5.0

[sonic turtle]

anyone?

[sonic lake]

In general if you click continue the packaging log file will show you where exactly the error comes from.

[silk lava]

I have several apps running on the OQ2 all done in 5 and 5.1

[sonic turtle]

I guess you are replying to different question. My question is what the equivalent of GetDeviceType() in OpenXR is.

[sonic lake]

Apologies, wrong OP indeed

@quasi goblet See if this helps. You may be missing the dot net support. https://youtu.be/52jI7Sxt3Kw

[tribal lintel]

I can’t look right now but within open xr there is something that returns the device string only if a successful open Xr call was made

So you’ll get null if no open Xr is present but then you can handle it there

Hello, I had a question, im opening my VR project after a few months

and the "motion controller pawn" is gone, it doesn't show up if i try and add it again. But in a clean VR project it does

I checked the files and its there, but in UE its just gone.

In a fresh project

my project

they are both running UE 4.25

i start building a level from VR TEMPLATE . i need to run from Oculus Quest 2 in standalone mode. I build the apk and all work great. 1 thing i cant get it work is the reflectnions, SSR , and reflection capture dosent work at all , anyone have some experience ?

hello there, anyone else experiencing an issue when switching to the spectator vr view and it looks completely different than the original vr camera? The spectator view looks bad and blocky compared to the OG vr pawn. Thanks in adv

[pearl lava]

Is there a way to set the IPD for the virtual camera? I found the "Eye offset for fake stereo rendering device" setting but it seems that this won't affect OpenXR.
Setting vr world scale to meters also seems wrong because that would affect tracking too.

[royal thorn]

Working on Oculus VR UE5.1 unable to see light build data and scene is darker. Put my skylight and directional light stationery now I can only see skylight more but can't see build data

[eager pine]

So has anyone followed the guides to get headless steam vr tracking?

I've done the setup 100 times about now, but heres a hiccup ive never figured out.
Most stationaries (95%) the headless method for steam vr doesn't work.
Mostly have to use laptops to setup the tracking, but suddenly they stop working as well.
When im saying it doesnt work, the controllers or trackers doesnt show up in steamvr anymore, but they are connected with a dongle and successfully paired.

Theres a weird error in the web console when this happens.

Yeah it's a headache, despite the fact that it's headless

Sorry wanted to make that bad joke. xsens, a mocap system, had a feature in its software that can activate the headless mode with a click of a button. I've always wondered how they did that because it was the only time it worked for me

[eager pine]

Well i figured a "fast" fix that worked actually, totally random and done it on three differnent machines.

https://github.com/TriadSemi/triad_openvr/blob/master/example_default.vrsettings#L3

Paste these into steamvrsettings in the first steam folder, then connect your devices, then you restart steamvr. You will see that it says you need a headset, just find the vrsettings file inside the steamvr folder this time and change "enabled" to ture

[slate frigate]

Does anyone have any good VR C++ tutorials I could follow?

For UE4 that is

[sonic lake]

@slate frigatenot a tutorial but back in time someone turned the standard VR template, which was BP based, to C++

I think if you Google it it may pop up

Found it: https://github.com/Sombusta/UE4_VRTemplate_Cpp

@left cedar

I really need your help with an issue I’m facing in unreal engine

It seems like I tried everything

But nothing helps

You may remember I reached out to you on YouTube about my shadow flicker issue

And you told me to decrease the shadow quality

And so I did

I went to the scalability settings and changed the shadow quality but it didn’t help

It just increased the shadow flicker

I also have a question

Do you remember what commit you built unreal engine 5.2 from

Because for me updating to 5.2 didn’t fix the issue as I said, and changing the scalability settings didn’t help either

Any insight you have on how I can fix the issue will actually mean the world to me

It’s very frustrating when you try fixing an issue for more than 3 weeks and nothing helps, so if you can tell me in detail how you fixed the issue I would be overjoyed

[left cedar]

im not sure tbh im using vive pro first gen and the flickers went away for me using 5.2. I didnt do anything special tbh

[candid cape]

So you just updated the engine

That’s all

Did you do it from the ue5-main branch though

Or did you change some of the settings on the default vr scene

If you changed any of settings do you remember wich

That would be very helpful

Aside from disabling forward shading so that lumen can work

Could you send me a scene with some basic free mega scan rocks or something with lumen and nanite that doesn’t have shadow flicker, like that I would be able to compare my project setting with yours
