what is the proper way of previewing VR rendering with UE nowadays without using actual headset?

looking to render single pass to some mock VR thing so I can see that the rendering works without having to put actual headset on and off

I tried r.EnableStereoEmulation cvar and SimpleHMD, cvar did nothing and simple hmd just rendered this

in Unity you get custom VR device named MockHMD that you can use for this, looking for some UE alternative to that

[zinc violet]

I mean this functionality in Unity now

[rocky nexus]

afaik there isnt one, why would you want one? shader dev is only thing that comes to mind, but actual device would still be better probably

[zinc violet]

for testing rendering related things

I've used that MockHMD thing heavily on Unity for this purpose

it's just PITA to put the headset on to verify individual fixes or fix attempts if you could just hit a button and visualize instantly on your screen

also used it in past for doing some benchmarking to see cost of individual effects in VR in general (but the Mock device has to be robust for this to make any sense and you essentially can make a setup with regular VR device where you just don't track head movement etc to get same consistent results)

it's also been convenient to be able to send VR rendering related bug reports when you can just visualize the issue instantly without pulling up the device

Very cool! Like that I could clone Half Life Alyx system with this. 😃

[idle osprey]

For those of you working on standalone Quest apps and you get the dreaded three dots on startup, what are some of the things you look for? I've no idea why I'm running in to this now. My level is just a basic Empty level in 4.27. All I've done is added some blueprint nodes that I'm porting over from a 4.25 project. It ran fine in Link mode and it used to run fine in the 4.25 project. I'm trying to learn what sort of thing I should be looking for when this sort of problem happens.

[rocky nexus]

that likely means that something early in startup is failing, like missing assets on first map. its essentially a crash, but quest fails to notice. run in development mode and check logs

[idle osprey]

Thanks. But very odd... All I added was a few blueprint nodes for movement. I'm going to try the nuke from orbit approach with my binaries, too. I shouldn't need to do a clean build when adding a few nodes, tho. 🤔

[rocky nexus]

regardless of the cause, guessing is usually poor choice

[daring pasture]

I'm in the same boat, moving my project from source built 4.27.1 to 4.27.2 has caused 3 dots issue. Nothing useful in logs or logcat

[idle osprey]

Hmm, I was already set for a development build. A full rebuild fixed it. Now, I am left not knowing. Where do the UE logs get written to on the Quest? I'm not finding them.

[idle osprey]

found them. adb shell "more /sdcard/UE4Game/<ProjectName>/<ProjectName>/Saved/Logs/*.log"

[wintry escarp]

does anyone know the timeline for ue5 working with VR?

[wheat holly]

Ue5 still supports VR just fine. If you mean Lumen and/or Nanite however then unsure.

[sturdy coral]

you can use -emulatestereo on the commandline, only for standalone; the editor and not just standalone/-game supposedly respects the option in latest ue5-main

there is also an hmd emulator built into the WMR runtime you can use to emulate everything including controllers I think

[sterile lake]

Any good resources for learning AR?

[zinc violet]

thanks, just tested and emulatestereo works but it kinda beats the purpose having to do standalone (would only need this for faster testing and doing slow standalone builds is the exact opposite). I read about WMR having that emulator too, you know how to enable it?

[sturdy coral]

there is a developer section of the Mixed Reality Portal app, I'm not sure if you have to enable the developer section or if it was just there by default, I think a tab on the left

[zinc violet]

I don't think the WMR app let me go futher without WMR device.. unless I'm mixing the apps here

but it's not a big deal, just wondering if UE actually had something like this built-in

kinda silly that they have emulation on standalone but not in editor

[sturdy coral]

-emulatestereo isn't great for testing most VR stuff; The main use of emulatestereo is for testing shaders and stuff that need to work in both eyes, I also use it for automated benchmarks to try and get close to VR (it doesn't use the visible/hidden area mask and the compositor doesn't run are the main differences in perf; also the default projection matrices are probably too low of an FOV to get the same results as VR). For gameplay it is better to create a mode of your pawn for 2d where can fly the motion controllers around in and stuff (the WMR one may be an ok enough substitute to making your own, but I haven't tried it)

[zinc violet]

yeah I have zero interest on testing any gameplay with that

just to see certain things render right

[ripe crypt]

Anyone used frame-sequential stereo with nDisplay on UE4.26/4.27

We are seeing ghosting, specifically on the left eye

[shut ermine]

Is UE4.27 or UE5.0 preferred for VR development these days?

Long story short: I tried VR in UE5 early access awhile ago and it was very broken (shadow artifacts only in right eye) so started developing a project in 4.26, now 4.27. Today I found out I could migrate to 5.0 but only with significant difficulty (was not as easy as using UE5 to convert it; required significant work), so would like to just pick 'the right version' and stick with it as I continue development.

Is there anything 5.0 gets me that I don't get with 4.27, other than a nicer editor? Lumen and Nanite not supported in VR so... what else? Is the performance of built projects about the same?

First Post

Hello there, I am having trouble setting up my Android SDK to be recognized by my UE5 project. Followed the ue5(4) docs online regarding this issue and I have had no trouble up to the point where I try to play the VR-Template file.

When I go to press play, the "VR Preview" is the only option grayed out. My Quest-2 is connected and visible by the project as it shows up on the list of devices (note, there is a m=small caution triangle next to the listing of the Quest-2 instance).

When I continue on and choose to play the level with the Quest-2 hardware, the level immediately fails and I get a message "SDK Verification failed. Would you like to attempt the Launch On anyway?" If I choose yes, nothing happens.

Again, I have followed the docs on how to set up your project for Android SDK/NDK and I believe I have followed them correctly. Please help Thanks!

[knotty folio]

Additionally, if I go to "Project Launcher" and select the Quest-2 instance, I get no errors on the tasks:

[knotty folio]

Here are all the logs when filtering for "Android":

been testing both ue4 and ue5 for vr here.. UE4 seems to be way more mature but the main concern here is that it's dead in the water

last ue4 update was from last december and it could be last ever ue4 version there will be

there hasn't been a single commit in ue github for ue4 this year

[shut ermine]

I guess if the current ue4 does what I need then I'm good...

[zinc violet]

it's mainly a concern if you have some bigger project that may need future SDK updates

Has anyone have had SkeletalMesh actors seemingly not spawn while in VR?

Seems like some kind of cullign going on

[jade kettle]

I have some spawning around a corner but I can't see them come around

Ah, I think i got the issue. Their movement through the world is based on root motion

But since they're around the corner, their skeletal mesh is not rendered, they're not being animated and thus they're not movign\

[sturdy coral]

Nanite works in vr now with one cherrypick from ue5-main

[maiden willow]

Can you elaborate?

[shut ermine]

Ah, cool. I won’t be using it in my project anyway (of the two, Lumen is what I’d love to have as my project is essentially 100% dynamic objects), but good to know!

[sturdy coral]

There is one git commit on the ue5-main branch that can be applied to 5.0.3 and fixes nanite with vr. I linked it in the past, can't find because discord search on mobile is breaking

Wow this is awesome. How's the performance?

Would I be correct in assuming this won't work on mobile VR anytime soon?

Best way to set the rotation the VR player is looking when the pawn is converted to a character?

[knotty folio]

Still having a lot of trouble with getting my UE5 to recognize the Android SDK. Can anyone help?

[clever iron]

When I use "Launch this level on Quest" I get a rock solid fps. When I package and install the game on the Oculus Quest, my fps goes into the gutter on the same level.

What gives?

For instance, PlayerController tick has 4 input events, it takes .4ms for "Launch this level on Quest" maps, and .8ms in packaged / installed versions of the same map

[knotty folio]

This (https://www.youtube.com/watch?v=i_eYPEylnTM) video shows you how to use the Oculus Link to show your project in vr, but still only a 2D version of the preview is accessible for me. The " VR Preview" is now available but do not get to experience the level in VR.

[knotty folio]

So I fixed my problem.. At this point I am just trying to document for anyone else who has this issue. In the Android SDK manager, There are 2 Android 10SDKs, choose the 10+(R) version.

[elfin stirrup]

Does it support simultaneous tracking of front and rear cameras in AR?

[neon oriole]

if i just have a general question about VR may I ask it here?

[neon monolith]

Hey guys!

Is it possible to make unreal engine bypass the 4k texture limitation on android/quest 2? For example, I need to put some 360 videos that are filmed at 5570xsomething something.. ahaha

But unreal only shows it at a cap of 4k on the quest... and that is noticeable enough to be annoying.

[willow fiber]

Does anybody familar with Android AR know why in Unreal the AR session appears to crash the first time it is restarted? It enters a FATAL_ERROR state that only recovers if you change the screen orientation or restart the app. Following that, all restarts work fine.

I've been trying to call the renderer functions that call when the orientation changes but with little luck, a lot of those functions have pretty deep protection levels in the engine.

[idle osprey]

My understanding is 4.27 for VR -- there's really nothing new in UE5 yet for VR. That said, 5.0.3 seems to be fairly stable now.

[idle osprey]

Why are you "choosing" one? The install script installs the right version for your editor.

[idle osprey]

Quest 1 or Quest 2?

[idle osprey]

I always use a Character.

@knotty folioBe careful with preview if you plan to make a stand-alone Quest app. It's not the same thing. You're using your GPU, not the Quest. Also, lots of people seem to get their game nearly done and then can't package. I recommend you regularly test on your Quest by packaging and deploying so avoid getting bit.

Preview is seductive and evil. 🦹‍♀️

[clever iron]

Quest 1, ASTC

[sturdy coral]

I haven't benchmarked well yet, haven't converted my scene fully to nanite (many meshes with translucent material sections). For mobile only maybe with the desktop SM5 deferred renderer support they have added to mobile, but I doubt nanite is working there yet

[idle osprey]

#virtual-reality message

You may find that useful. 🙂

[clever iron]

Oooo shiny. Will try that too.

[blissful rain]

Quest 2 height is busted for me. Based on a class that's based on Character class. My camera is set to "Lock to HMD". No matter whether I set my camera Z to 0, to 90, to CapsuleHalfHeight*-1, it's not right.

Either "Floor Level" makes you as high as 2 full people, or "Eye Level" makes you short as a 6 year old.

I don't know what to do. I've set my guardian in a standing position and a sitting position twice, still no success

I've tried this but it does nothing... I assume the "Lock to HMD" will disable any further modifications

If anyone could at least reply saying that they have no idea or that I missed something completely basic, it would mean the world.

[tired tree]

@blissful rain you don't set the camera to a height, as tracking overrides that

set the PARENT of the camera to -HalfCapsuleHeight

[blissful rain]

Thanks! I had just figured it out. There was no parent above the camera aside from the capsule component, but indeed, I added an empty scene and offsetted that to -88. Thank you!

[tired tree]

@blissful rain might want to add an additional -2.15 UU of offset, the capsule for the character hovers that much on average above the ground

its technically an allowed range but it almost always sits at 2.15

[blissful rain]

Good insight. Thanks, will keep it in mind

[clever iron]

That definitely helped my frame rate, but probably isn't root cause for my problem

Still drop about 25 fps from the launch map button vs packaged install

Hey, I have made a guitar with different box collision on the neck representing different chords and plays different sound in vr, I want my left motion controller to snap to the neck area of the guitar and holds that part and only be movable up and down the neck. currently the motion controller have free movement and can be moved any direction and plays the sound when it collides with the box collisions. I'm wondering what is the best way to limit the movement only when holding the guitar?
i tried changing the relative location once the player holds it, but that just resulted in floating hand stuck in air

[molten crow]

Hello everyone, after reading @wind yacht and @modest cliff 's conversation from a year ago about about the AR material passthrough and I am still having a bit of trouble figuring it out.

I am working in android, and my goal is to be able to control the camera passthrough by multiplying it with a parameter in order to fade to black, without affecting any game objects.

I saw for android I need to use a dynamic material, with external camera set to true. I'm struggling to understand which material to use out of the options inside the AR utilities plugin folder, and if it matters where I create it, so far I've attempted to create it on the AR Pawn .

Creating the dynamic mat on my pawn
Then testing it with a sine function to ensure its fading back and forth

This is a test i have set up to see if the effect works

So my main questions are, which material do i use for the dynamic material creation in this case, and does it matter where i create it. Do I have to assign to something? or does the passthrough material component handle that?

[molten crow]

Did you go to the ar session data asset and ensure that "enable automatic camera overlay" is checked?

[fading drift]

Don't know exactly where to place this, but I have decals in a VR UE5 game that ends up flickering pixels, any solutions?

[sterile lake]

It cannot be completely corrupted. because the camera works in ready projects.
Since I couldn't solve this problem, I deleted the ready project and I'm coding on it again. I don't understand why, but it may be something related to the map. I'm not sure exactly

[sterile lake]

yes

for some reason i cant use the vr editor in ue5 but i can do vr preview. any idea why

UE5 VR Template GPU Fatal Error - I haven't been able to fully bake, compile and play a single VR project using ue5's vr template. I always get the same fatal crash message on both computers. One has a 3090Ti, the other has the 3080 laptop gpu card. I'm using Lushuang GPU renderer to bake all lighting. No raytrace, no lumen and also no forward rendering, just standard bake. Largest size mesh at 1024 but almost everything set to 256 or smaller. I did however get things working when I baked using preview but as soon as I set production quality and compile, experience always crashes. Side note - I have noticed considerable crash issues when dealing with navmesh volumes being slightly too large. Any suggestions?

Hello everybody, I am a still enthusiast 58-years-old VR-addicted developer which worked with Virtuality stuff back in 1990 and with UE since latest versions of UE3 and Oculus DK1, so all this VR stuff sounds sci-fi to me. THANKS to everybody here for your work. It is AMAZING. Then: I am trying to get a hang on the XR Template in UE5 but there are several things I cant get. I am on UE5.0.3, latest MacOS. First of all, I searched for info and a tutorial-howto etc specific to UE5 and XR Template (also here in Discord) but I have found nothing relevant, am I missing something? On YT you can find stuff but is relative to 4.27 usage. So: I see that if I rebuild the lights in the XR Template, as is when just created, it does not work. I get very dark lights. I suppose I must revert to “old” UE4 static light baking, Nanite/Lumen is not supported on Oculus but it seems enabled by default in the XR Template (settings/rendering/global illumination). Changing that, settings lights to static and rebuilding seems not to work anyway, so: how do one reverts to “old” UE4 lights baking behaviour? Do one have to do that when deploying on Oculus or is there any other better usage pattern? Or, what am I missing? Or, is this a MacOS bug? Or, should I give up and get a beer and stop asking stupid questions? I am tagging @hallow knoll as the author of the template and the YT tutorial(s). Thanks again.

[tired hamlet]

Do everybody here still need to add "/OculusVR/Materials" to "Project Settings > Packaging > Additional Asset Directories to Cook" to correctly deploy the vanilla XR Template to Oculus2, or it is a misconfiguration of my system? I can see that, if I REMOVE the oculus packaging and get an executable running in a window inside Oculus, it shows a modal with a "PokeAHole material not found" error. I had this since 4.27, i.e, the new XR Template. This causes the dreaded "three dots forever" when you deploy and run an oculus-packaged executable without the fix.

[tawny halo]

is there a way to change betweend vr/flat screen in game?

[idle osprey]

Should be. I haven't tried. You'd have to posses a different pawn, most likely. Alex with VR Playground has a good video on how to handle it on startup by detecting whether or not the VR headset is connected. I think you could just disable the HMD, switch pawns, and you'd be ok. That's how I'd try it.

[jovial violet]

Hey everyone 🙂 Still quite new to programming but wondering how I would go about making an object in VR that I can hold onto and pull/ drag but keep the object constrained in space so it will only rotate on axis instead?

I kind of have half the logic down by having my VR hands grab the object and attach to it, and having the object constrained in space with physic enabled. But the problem is I cannot drag the object as I lose all control of the VR hand itself, then when I let go I have it so the VR hand snaps back to my controller location

am I going about this the wrong way?

[marsh crystal]

Not sure but I verified it’s a bug and happens with the default character so I submitted a report

Video of pressing jump button on standard controller. Works as intended.

Looks like our own wonderful vr_marco answered this question last year: https://forums.unrealengine.com/t/vr-mode-oculus-quest-controller-not-working/467790

Further down, someone says it's working in 5. 🤷‍♀️

Yeah it works in 4.7 fine I’ve used it. But my project is UE5 😅

[rocky nexus]

vr probably isnt very high on priority list when new fancy stuff is very heavy on consoles

[marsh crystal]

Unfortunately I did too much work in ue5 to change back now 😦

[ebon sorrel]

You have to have your SteamVR on and running with the quest in Rift mode BEFORE launching UE.
Then you also have to have the plugins turned on.

[ebon sorrel]

Oh no! The whole project I wanted to do was based on being able to assemble my objects in VR.
Can I migrate assets from UE5 into a 4.27 project?

[zinc violet]

ue doesn't officially support backporting, you might be able to do it manually but things could still break

one trick that worked on ue4 when moving backwards for actual levels was to copy + paste whole level contents from newer editor to older editor since the copy/paste was serialized the same way even if the physical map files weren't backwards compatible.. there's a lot more changes between ue5 and 4.27 though so stuff like that might not work anymore

you'd still need to have identical asset refs on 4.27 first for this to work

you could also try exporting the assets out of unreal 5 and importing them back to ue 4 with some DCC roundtripping tool

it's going to be pain either way

Hey guys, any idea why my controllers are rendering black after I build a game (exe), they are completely normal looking when I test in editor but it seems they do not have a material applied in game (might just be the world grid material as the game is unlit).

This is the controller setup code

NavController = CreateDefaultSubobject<UMotionControllerComponent>(TEXT("NavController"));
NavController->SetupAttachment(TrackingOrigin);
NavController->SetTrackingSource(EControllerHand::Left);
NavController->SetShowDeviceModel(true);

This is editor vs built game

actually i used both of them and it worked for the same internet connections correctly. But when we have different internet connections it gives error

[hallow knoll]

@ebon sorrel @marsh crystal VR Editor Mode works in UE5 but only with the respective native plugins (OculusVR plugin for Oculus device, SteamVR plugin for SteamVR device, and OpenXR plugin disabled). We're currently working on OpenXR support for VR Editor and Virtual Scouting.

[hallow knoll]

The VR Template's lighting in UE5 was baked using GPU Lightmass. While any GPU can render lightmap data generated by GPU Lightmass, only cards with Ray Tracing support can generate it. CPU lightmass works just fine with the settings in the default VR Template map (not dark), but I've never tried that on a Mac. I should note that while there are folks using Mac for VR development it's not something we actively support.

[supple lotus]

Hi!

I am running into lighting issues with UE5 - Oculus Quest 2 as well. I have set up a scene, baked lighting with GPU Lightmass, and when I deploy the project to oculus, the lightmaps are missing and pure black

[tired hamlet]

hi, you too are on MacOS? @hallow knoll was saying exactly that to me... I am on MacOS, when I create a new VR Template and just rebuild the lights I get a completely different result from the one you have in a brand new VR Template. I suppose that Mac HW works in a significantly different way than Windows one...

[tired hamlet]

Thanks @hallow knoll . But, what does it mean to use UE5 Lumen engine in a Oculus 2 native deployment? Is it supported? I remember someone saying it is not... Shouldn't be better to change the VR Template settings to SSGI, baked static lights etc (i.e, the UE4 setup) when deploying to Oculus native android? I am a bit confused.

[supple lotus]

It’s on a windows machine.

[celest patio]

Whats the best way to throw objects? It seems they throw fine if you don't weld them together, but if you weld them to the hand like in the VR Template, when you unweld them upon release, they dont have momentum and just fall down. Is there a way to copy the momentum to them after unwelding them?

[vagrant folio]

#virtual-reality message this should help you along

[alpine robin]

Does anyone else have problems with the InputAction event for Vive controller grab buttons? It seems like it fires twice on Pressed, and on Release it first fires Release and then Pressed again

Fixed it with this simple setup, but still weird

[white rune]

Has anyone tried multiplayer VR using VR Preview? I'm trying to teleport in one of the clients but the teleport trace doesn't even show up. It works when there's only one client tho.

[golden current]

I've only seen tutorials use the VR template, is there a resource that teaches VR from scratch?

[celest patio]

cool thanks

[supple lotus]

@tired hamlet @hallow knoll I have found the culprit in my issue. I have used megascans materials in my project. Just simple opaque ones, yet they appear black on Quest 2. Re-using their textures and making new materials from scratch, using the bare minimum of nodes works perfectly

[tired hamlet]

Maybe resolution too high? Did you to scale down the textures or use the lowest res?

[supple lotus]

Yup all lowest possible

[real needle]

inside ue, how do i let q2 let render the game?

[sonic lake]

To play directly inside the Quest you need to Launch your project to it

[real needle]

rendering it, not just playing in vr

ohhhh. q2 is android? but building the game every time is.. ridiculous

[sonic lake]

During development you typically use the Oculus Link to play from the PC but, yes, to launch inside the device it needs to build first.

[real needle]

that makes making standalone games so unattractive

[rocky nexus]

eh you dont need to run on device all the time, link is just fine for dev as Marco said

[scenic junco]

Anyone at all had issues with ue5 not receiving index knuckles axis input but getting every other button in "debugshow INPUT"

[real needle]

not if im testing if it can run on q2

[rocky nexus]

for that you need to build, like with testing on any other platform. still that usually is small part of dev time

[tribal lintel]

general rule of thumb: anything audio/visual deploy it to the headset every time. If your working on logic, you can just use VR preview to be quicker. you should still deploy to your headset frequently to test.

[idle osprey]

...general rule of thumb... package and deploy to the hardware you're going to release on. Don't expect PIE to cover your butt.

[delicate isle]

I am that one other person using Mac to develop VR 😅

[delicate isle]

I am also experiencing the same issue. At the moment I think that static lightmaps on MacOS are broken. I have been testing this using an empty project and a variety of static lights and the scene always ends up black. However, the lightmap textures underneath World Settings seem to have the lights visible in the baked textures - they're just not getting applied to the scene during the render stage.

So this is a less a problem with the VR template and Mac, and more with static lightmaps not being rendered properly. The lightmaps will also not show up on the headset so it seems to be an issue stemming from after the baking process

Here's a quick example of a test scene (pre-bake) with a portion of the resulting packed lightmap texture. The scene goes black immediately after baking (all lights are static) and I'm just using default cube static meshes from the engine, so all of their lightmap UVs are set to index 1.

When packaging for the Quest 2, these lightmaps are still not being picked up by the Vulkan renderer on the headset. I am unsure if they are even getting cooked and packaged along with the level when pushing to Android.

[tired hamlet]

Same conclusions here. I hope they fix it. I am asking myself if this has something to do with the new defaults for the templates, using Lumen, and if reverting to SSGI and mangling around in the settings could fix it, or if this is totally broken in UE5 on MacOS. I will do some tests if I get the time. Sure it would be bad to be confined to UE4, but knowing I am not alone to experiment on Oculus with MacOS is something at least 🙂 . In fact we do small custom stuff for which it is not mandatory to embrace a officially-supported environment (read: I can't stand Windows, having used it for decades...)

[delicate isle]

I've tried baking with pretty much all of the Dynamic GI settings including Lumen and screenspace and got the same result

[tired hamlet]

ok... not going to reinvent the wheel. Thanks, let's wait and hope for the future and stick to UE4 in the meanwhile.

[cold sluice]

Starting a VR project with the VR template in UE4.27. When I try migrating assets from other projects to it, they don't just show up in the VR project. Some migrated materials don't work too.

[thin hearth]

Which online subsystems are supports VR with different internet connections

[abstract blade]

Have you looked at the scene in editor using Vulkan/Android preview? How does it look there?
The scene goes black because the lights are set to static and you are using lumen I presume? Lumen does not like static lights.

[ember meadow]

I tried to use media player in vr, but it did not work

In other project without vr it works

[delicate isle]

Lumen is disabled. For dynamic GI and reflections in the project settings. Lightmaps have baked data in them but they aren't being applied to the scene.

[trail basalt]

Did you figure out what the issue was? I'm having the same problem.

[chilly pasture]

I am having a weird problem with only some users, but not all of them, and i have noticed if we fix the guardian of the quest device, it gets fixed. so sometimes, Camera start with a relative offset from the Pawn WorldLocation, which creates problem, like actor looks out of the seat or something like that.

Does anyone what should be the best approach to fix this problem
Thanks

Exponential height fog error in vr template project while building new level

causing a black bg

[hallow knoll]

If the "other projects" are created with a newer version of the engine, you won't be able to load assets created in the newer projects, in an older version of Unreal

[hallow knoll]

There's no difference between a VR project and a regular project when it comes to online subsystems. However, if you're creating a multiplayer game for the Oculus Quest (standalone), you should use the Oculus Online Subsystem

[hallow knoll]

Please file a bug report and/or post your findings on the Forums

[marsh crystal]

Ohh ok thank you I'll try this later today! Is there any update on the issue I posted here? Im pretty sure its a bug and submitted a ticket. I cant proceed with my project now because Ive upgraded to 5.0.3 and it was fine in the previous version.

#virtual-reality message

I dont really know what to do cause using this button is very important to what I'm working on.

[dreamy ivy]

Can you show the blueprints. I doubt this is a bug tbh.

[copper zenith]

Looking at the 1st picture, am I correct that this frame in unreal insight shows a bottleneck in the render thread and not the CPU and GPU?
I'm working on a VR game and I have terrible performance in a small room, with static lighting, stationary lights, and a 440k mesh.
The 2nd picture shows my framerate/frametime throughout the VR session in the editor.
I'm running a AMD Vega 56 OC and a AMD Ryzen 3900x

[thin hearth]

I tried to use oculus OS. but I couldn't found any documentation. Then I tried to use the nodes and create a basic session. It gave some errors

[mighty carbon]

Has anyone tested Chaos in most recent ue5-main branch ?

I wonder if it's usable yet (there were a ton of issues with Chaos physics in VR)

[abstract blade]

If you move your lights when the scene gets dark and then press revert, does the light come back?
How does it look if you change your posprocessvolume GI setting to none, still dark?

[copper zenith]

Does anyone know why would the framerate cap at 11ms (90fps) or 22ms (45fps) in VR? I'm running UE5 in editor with Oculus Quest 2 using Oculus Link.

Could it be my USB not being 3.0?

[thin hearth]

Hello, I used the web browser plugin of the unreal engine and I can use it on a PC successfully. But I tried it on VR I can only see a white blank screen

[hallow knoll]

This issue is known: https://issues.unrealengine.com/issue/UE-150021

[thin hearth]

There isn't any solve for this right ?

[hallow knoll]

Not currently. For clarity this is only a problem on Quest Natively, not if you're using Quest w. Link.

[thin hearth]

Okay thanks

[thin hearth]

I have a question too. You know there are some plugins for the web browser. If I use these will my problem continue

[delicate isle]

Since I'm targeting the quest I don't have a postprocess volume. I think the lights come back when reverted but I'll check.

[sand raft]

does anyone know how I can change the audio device unreal outputs too so it uses the headphone in the VR headset instead of the windows default speakers?

[marsh crystal]

Ok so I fixed the issue but it is something that wasn't an issue before 5.0.3 and now it is. What the issue was is this. I had made a custom axis input named something other than "Jump" with the jump button assigned. This way when I held the jump button down for a specific time It would open a gate to allow the axis value of that to flow through. But instead I just removed that whole axis thing and now I'm just having the jump button go into a looping timeline that only opens when the jump button is held a certain amount of time. Which I probably should have set it up like that before tbh. But yeah , my fault but definitely not an issue before the update as well. And the problem only occurred on oculus touch not any other controller.

[tribal shore]

So i'm super new and following some tutorials. Im getting hung up on should the player have an actor?

Im just building off the demo, but I can't figure out how to damage the player.

[round cliff]

Hi! Has anyone used Shared Spaces?

[somber pulsar]

whats thaty

[cold sluice]

Unreal Engine 5 doesn't ship with the Oculus OpenXR plugin? I can't see the option there although it's available for 4.27.

[ashen dome]

Thats not an unreal thing. Its a windows taskbar speaker icon change audio output setting

[sand raft]

For this project I need to be able to set the audio output different than the windows default device. Is this possible? I couldn't find any documentation on how unreal sets it's default device. I assume it's in engine.ini but I didn't find it there

[radiant garden]

The Lyra example has some settings for switching audio output device. Could look at it to see how they did it.

[sand raft]

Thank you! I will check it out

[radiant garden]

The settings are on the front end. If you hit play, then hit escape -> "Quit Game", you'll arrive at the front end and can see the options I referred to earlier

I don't recall if the "in-game" options have the audio settings.

[sand raft]

Even in an ini file would work for me. I'm not developing a game but making an application to interface with a flight simulator. Unreal is driving the VR system and audio output is being use for haptic feedback. Another 3rd party program is handling in cockpit audio.

[radiant garden]

I'm sure it ultimately ends up in the player settings somehow. I haven't actually shipped anything with UE yet so I haven't handled that production detail. You've undoubtedly had difficulty finding anything about it because it isn't a particularly fun topic for youtubers to make tutorials about (most hobbyist developers don't know or don't care).

[sand raft]

Yup when using tools in way they were never intended documentation is very scarce. Thanks again for the help!

[thin hearth]

I've built a package from ue5 for VR (quest 2). When I exit from quest 2 's safe area and if the application is opened. The build is broking. I mean, I can't open the game. Just a black screen appears

[sinful grotto]

Can anyone tell me why unless Steam VR is running I cannot test with VR? Is there a setting somewhere or did steam VR take control of the OpenXR Runtime?

[glossy jackal]

I'm trying to add Index support to my existing product made in UE4.17 and considering installing "SteamVR Input for Unreal" plugin. However, I've read some complaints about inputs working in editor but not after packaging. Does anyone have experience with this plugin in 4.17? Was this issue fixed?

[covert ferry]

Hey guys,
Can I please get some advice on settings for nav mesh so that I can walk around the van in vr more freely ? as you can see there is only a lottle spot in the nav mesh, I have been playing with cell size which seems to have helped

[real needle]

Make the van "does not affect nav mesh" and place invisible walls that block the navmesh where you want it. an alternative would be to use a custom collision mesh with no roof and doors for example. @covert ferry

[gloomy crescent]

Is there a way to control a vive tracker that doesn't involve live link?

Also, is there a way to keep my live link binds everytime i restart the project?

Is livelink even supposed to be used in a shipped application?

[sinful grotto]

@gloomy crescent Not sure if this is what you need but it includes info on using Vive trackers. https://varjo.com/vr-lab/recipe-using-motion-trackers-with-unreal-engine-projects/

[gloomy crescent]

I've cheked that briefly

But i need a solution that has tracker roles that aren't in SteamVR

[sinful grotto]

https://developer.vive.com/resources/openxr/openxr-pcvr/download/latest/ maybe? or am I following the same leads you did?

[gloomy crescent]

Right now my problem is

I need to track a set of objects and track them in UE4

But i need a way to assign these trackers in a shipped build

and livelink doesn't exactly seem friendly for shipped stuff

[sinful grotto]

can you add them as additional motion controllers?

[gloomy crescent]

I'm gonna try that next

As soon as I get home

But I was wondering if there was a way to add custom tracker roles to steamvr

[sinful grotto]

It looks like there are basically the same entries in the Steam VR SDK. GetTrackedDeviceClass, GetTrackedDeviceProperty, the Steam VR tracking HDK might help as well

https://partner.steamgames.com/vrlicensing#DevKit

[somber pulsar]

Not sure if this is a vr issue but when i run my game it opens and the map flickers for a second then changes to this I have tried changing the map to the right one in console and it goes back to this any ideas what could be causing this

[worthy quest]

Hey, has anyone worked with the Focus 3 yet? My application (PCVR) works well with the vive controllers and I was wondering if it would work with the Focus 3 controllers but I don't have a way to test it yet and can't find the controls in the project settings/input section for it? Any suggestions? Thanks 🙂

[hallow knoll]

The Oculus OpenXR plugin was only temporary in 4.27 to provide OpenXR support for Oculus Quest. It's no longer needed in UE5.

I'm assuming you're running in to this on a Package of an EXE?

[mortal spire]

i do not know what you mean?

well... I went on a limb and restarted my UE4 but this time with admin privillages and the error went away... 🤔

hah, ok. I was going to guess it might be a permissions thing.

This is what I see when I build:

So I'm guessing either a different user installed UE on that system? Or you ran out of file descriptors? For one reason or another, you didn't have read access to the file.

Why even use a navmesh for your player, are you using teleport movement?

[gloomy crescent]

Anyone has any experience with vive trackers?

I can't seem to get them working under special_1 through steamVR

[polar valve]

You need to use the WaveVR plugin for the Focus3 https://hub.vive.com/storage/docs/en-us/UnrealPlugin/UnrealControllerButtons.html

[hidden crest]

I believe the template in UE5 defaults to Forward Rendering now so it doesn't support SSR.
If you must have SSR you can switch to Deferred Rendering (Project Settings/ Rendering/ uncheck "Forward Shading") but it will require a lengthy recompile.

[tranquil nexus]

got it! thank you

without MSAA it looks pretty bad, can live without ssr 😄

[worthy quest]

thank you very much!

[strange agate]

Late, but, I noticed with my vive setup at home, (I assume I've forgotten to set some setting somewhere) I have to put tape over the interior light sensor on my headset/put it on for any of my controllers to properly work, that's kind of my first step troubleshooting if something is acting weird around peripherals. I've disabled sleep mode and a couple of other settings but haven't fixed that yet.

that may not be related at all but I figured I'd shoot a maybe out there

First try with image tracking AR in UE5 https://youtube.com/shorts/Td4F9IExObw?feature=share

[hidden crest]

I tend to agree but with UE5 you can turn on temporal upsample and "r.Tonemapper.Sharpen 1" and you get reasonably close to MSAA clarity suing TAA.

[inner gust]

Hey everyone ^^
Can anyone help me with a problem i have with my project. Basically I'm trying to restrict the player motion once it grabs a specific object ingame. I want the motion controller to snap to a certain position and only be movable in one direction which is up and down of that object. I have tried adding a physical constraint to the motion controller and the object but that did not work. Any other ideas or method to achieve this ? 🙂

[vivid spade]

Whats up guys I wanted to talk about recoil in FPS VR games. Has anyone found a solid system for implementing recoil? Looking to get ideas improve upon what I've got.

[strange agate]

My first thought on this is just to make the real motion controller invisible during this interaction, and then on the actor being interacted with, have a model of the controller on it already that is set to not visible, and enable it during the interaction, with code that ties it to the vertical movement of your now-invisible (but still tracking) motion controller.

[strange agate]

I think most VR examples I've seen are the common ones in FPS games; I guess your design question to start with is if you want players to be able to learn a recoil pattern and adjust, or if you want a continuous stream of fire to always get more and more inaccurate as you go, or some other behavior. Also take into account that moving your mouse to compensate isn't the same thing as aiming controllers, as the real-space physicality means the gun needs to reset to "accurate" while mice can just be neutral input wherever they ended up, and controller sticks reset to center.
Some games choose to have a widening cone of fire, so continuous fire with guns that aren't configured to have a limited effect on this, or don't have bipod support or something, will get less accurate the longer you fire.
I think Onward just makes the bigger guns rotate physically upward as you fire, hilariously shooting yourself if you ignore it for long enough, but effectively meaning you really need to let go after a few shots to remain effective.

Passed that, visually if you have single shot weapons you can add a lot of seen recoil in but limited gameplay impact (A shotgun can return to "accurate" by moving a ton after the shot but returning to neutral before its firerate cooldown is done).

[elder nimbus]

is it possible for me to play one of my normal levels in vr mode?

its greyed out for me

[vivid spade]

I want a randomized recoil pattern, but even before I implement that my real question is how are people handing the logic of bumping the gun upwards and to the side and breaking away from where the hand is actually pointing. Since I cant "force" the motion controllers to kick upwards I'm curious what kind of logic people are using in their BP's to mimic a recoil effect.

[strange agate]

Depending on how your interactions are set up, if your gun fires a projectile from its actual muzzle, you can wiggle the gun itself/projectile emission point around, but that will be VERY inaccurate very quickly.

I remember hearing a long time ago a dev describe their recoil pattern on a game (and am filling in a few blanks as I've forgotten who or what game)... they had a plane that projected out from the camera (the gun in VR would be better) at a set distance based on their level design, and the logic would cycle through an array of xy coordinates on the plane itself, projecting bullets from the gun to that plane point, after which point gravity began affecting them. Which means at close range there was very little loss of accuracy, the "plane distance" and points on it were known quantities which could be balanced with reliable data, and at further distance past the "plane distance" it got very inaccurate. By adjusting the xy coordinates of each aim point and distance to the plane point, you could have guns that recoiled in unique ways very quickly iterated on. That could easily be hard coded or mathematical formula.

That's one real specific way to do it, I think a big question is what range and what kind of weaponry do you think you'll be dealing with, (realistic and you're trying to make the gun's performance match a real life reference, or not concerned there) and how do you want the player to be able to interact with your recoil mechanic (Do you want them to be able to compensate for the recoil, or feel like at distance they need to burst fire, but close range they can sweep the muzzle without worrying about it, etc)

Sorry for the essay you really got my brain going thinking about it

[somber pulsar]

does anyone know how I can stop steam vr from taking 60 - 80% gpu and 20 - 45% gpu on idle is this a bug or a setting making testing the game impossible

[strange agate]

Not sure if this is what's causing it for you but on some relatively lower end PCs, steamvr running "Home" when idle causes higher than expected usage. Can disable it here:

if it's not running home tho, dunno

[somber pulsar]

its running the screen where thers like white circles on the ground and the background is dark idk if thats home or not but ill try this

Anyone ever have an issue with Oculus Developer Hub saying it detects multiple accounts when you only have 1 account signed in and even on the device? Was oculus just being their typical self and letting Jr programmers push to production again? Probably.

Hey guys, I would like to make my vr character's head invisible to the camera but I want other players to see it, how can I do it?

[shy steeple]

There is a boolean called "OwnerNoSee" under Rendering section in the details panel. That would do the trick 🙂

[real needle]

Thank you very much

[real needle]

I did that but because my character is one mesh I cannot see the character now, is there a way I can only make the head invisible. I have tried hide by bone name but then other players cannot see it :P

[maiden willow]

You will have to separate the head from the rest of the mesh then. I don't know of a way to do what you are asking on a single mesh

[real needle]

Yea working with one mesh really sucks tbh, thanks for your message. Have a great day!

[mystic token]

Hi, does anyone knows how to get a reference/pointer to the instance of IXrTrackingSystem?

I want to call that function but its not static

IXRTrackingSystem::GetPlayAreaBounds(EHMDTrackingOrigin::Stage);

[tired tree]

@mystic token IXRTrackingSystem* TrackingSys = GEngine->XRSystem.Get(); if (TrackingSys) {

[mystic token]

Thanks

[shut flicker]

hey all, whats the best way to calculate the body direction in VR?

[hard relic]

Hi there, i'm not able to see may Cg_element in my Quest. It display Black. Any idea? Maybe it's not compatible in forward Rendering and without HDR?

(it's like a CCTV)

[ember forum]

does quest2 just not support ue4 landscapes? my maps with landscapes all crash but maps without them run fine

did you find a fix for this, having same issue

[sullen kite]

I’m on 4.27 I don’t use 5 for vr btw unless the get nanite to work for vr I’ll move to it. So I’m 4.27 landscaped are fine

[alpine robin]

Does anyone know if it's possible to set the roomscale root to some other component than the root component? I'm trying to parent the root to a capsule for physics based movement.
Edit Nvm, apparently it's not even based on the root component

[native wigeon]

Does anyone have any good resources for setting up a vr pawn with a body? I've been trying and it isn't going well.

[ember forum]

im on 427 as well.. i managed to get it working with smaller landscape but it sucks its so many triangles being drawn, im going to switch to meshes

RoundRobinOcclusion has anybody used it, know of documentation about it?

[real needle]

is there no way to to level design in vr?
i cant put on and off the quest 2 every 20 seconds.

has anyone written "gorilla tag movement" aka walking with hands and can share the code? marketplace has it, cost 80 euro.

just look at this. i sculpted this in vr. https://images-ext-1.discordapp.net/external/dedBBtOVC_VGTA_Tv_DjLhXRbAXzFK9_vv_tmO-50qE/https/i.imgur.com/Z1zHiMn.jpg?width=705&height=358

if i would just have 10 rock assets and then try to make environment with these 10 asset, it would have never have such a interesting layout like in the pics here.

How is UE5 for VR dev or is it better to stick with UE4 for now?

[vivid spade]

Yo I'm using UE5 and love it

Currently have full body tracking + hand tracking, Ladder climbing with physics, and picking up + firing a gun with recoil implemented and its all been straightforward

Currently I'm making a shooter so movement, jumping, climbing, shooting, and going prone/crouching are the bread and butter mechanics that I felt would be the hardest to implement but I've got them all knocked out in 3 weeks (everythings a little rough obv but mechanically there) so I'm confident at this point that UE5 is a good choice for VR dev

[vivid spade]

@native wigeon I've got one set up and its working nicely, what are you struggling with?

[native wigeon]

It's almost like my camera component is detached from the physical pawn. When I turn around I see my own body so to speak.

[vivid spade]

Whats your component setup in your pawn?

@native wigeon

Anyway assuming this is in UE, yeah the camera does what it wants regardless of the pawn, I've got a VR Character instead and it has similar initial issues. You've got the get the cameras position + rotation and likely do some rotating + moving of your pawns components to get it to match the camera.

[native wigeon]

Component set up? Sorry, I'm still a fledgling dev. 😅 Just trying to experiment. Could you tell me what, in particular, you're referring to and where I can find a visual representation of it?

[vivid spade]

Yeah for sure, Actors are individual "objects" within the environment, and are made up of components. For example, your VR pawn is an actor that contains two controller components, and a VR Head component. Heres my VR actors component setup

Where components are placed in the heirarchy can determine their position in-game. So for example I've got two hand components underneath each controller component, and now those "hands" will follow the position of the controllers they are children of.

[alpine robin]

Does anyone know where on the HMD the tracking data is located when you get its location and rotation? I'm trying to match it so the head of my character rotates like the head of the person wearing the HMD. I think I will need to offset the head from the HMD for it to work.

[outer flicker]

Something like this?

[alpine robin]

No, I meant like the physical location on your HMD. When you get the location and rotation of the HMD, you get a single location and rotation pivot. Where on the physical HMD is that located (at the front, top, center, players eyes, etc)?

[outer flicker]

I see, thats a great question actually. Id love to know myself.

[alpine robin]

From my testing it seems to be somewhere near the eyes, I managed to offset the head pretty well through trial and error.

[covert ferry]

Hey guys,
When I create a user interface BP in UE5 It does not have a canvas panel by default.
but all the tutorials I am watching have it in there the moment it is created.
I am asking this because I do not know what size I should be making the canvas panel

[real needle]

guys where do you do version control?

aws is too expensive with 30 euro monthly

[strange agate]

Has anyone been experiencing issues with OpenXR in unreal 5 and it not tracking Vive Wands correctly?

It randomly physically tracks them when I press buttons but the model doesn't show up and no buttons on fire off an input event

[strange agate]

Hmmmmmm steamvr beta might be the solution

I'll have to go test in the lab tomorrow but at home on emulation seems like its working

[hard relic]

hi there, still stuck with scene capture 2D that render Black on my Quest. Anybody know if it's possible to use that inforward rendering, when HDR is off?

[narrow thunder]

Does anyone know how to setup a Unreal Game using the Guardian System? I want to make a full room scale game for the Quest 2 and I need a way find a way to make sure the player starts at the center of the playspace.

[hard relic]

I tried something like that in the past. The problem was that you can't disable the home button that recenter and reorient the view....

[strange agate]

Sure but you'd have to think pretty hard about how you want that to work.

Think of Wind Waker's song system, up down left right neutral. That would be pretty easy to implement.
For your linked gif, it depends, that looks like downupdownup backhold-forwardhold. Adding the 3D dimension to it could work, but will be trickier. Then you have to think about the feedback for the player to know what to do and when they're doing it right, especially if the controllers leave their vision. And what does this system result in?

You could create a pattern tracing mechanic, where you select the spell and then it walks you through putting your wand in the right patterns, that's just saving coordinates and visualizing them.

maybe have a timed component on each "section" of the pattern, and a bonus to damage or whatever if they go through it quicker

VR multiplayer tutorial please ?

Recommendations

[whole zenith]

Hello, I'm developing VR with Unreal for the first time, what docs are must-to-read?

[sonic lake]

@whole zenithIf I can offer a suggestion, create a project with the VR template, play with it, then start analysing how it works, modify it, break it, fix it

This process is worth reading many documents in my opinion

[whole zenith]

I already started with that template, i'm reading articles while it builds the first time

[sonic lake]

Your starting point in the official doc is here: https://docs.unrealengine.com/5.0/en-US/developing-for-xr-experiences-in-unreal-engine/

[trail shale]

how do you make the game load switch to steam VR while it loads so the game doesn't hitch and make them motion sick

[manic tapir]

My ODH isn't recording my device screen
It stops recording a few seconds after I start it

Hey all, I want to make objects so they don't pass through other objects. Is there a way to make it other than collisions or physicsconstraints?

[wind yacht]

Is it smart to start using UE5 for Quest development or should I still stick with UE4.27?

I have a big project I have coming up for the Meta Quest 2 and I have my most recent Quest 2 project in 4.27 and was thinking if UE5 is ok I'd transfer it up and use some blueprints I made in the old project

[trail shale]

SHOULD I still be using this to start my game, - mainly the dynamic resolution and pixel density stuff?

[idle osprey]

My own opinion is that you should stick with 4.27. There's nothing in 5 that is for VR and there's some changes to lighting that may cause you grief.

[wild depot]

Anyone have any good resources for level streaming on quest? I’m using streaming to create a procedural dungeon (spawning random rooms) and everything works on my computer but fails when packaged to quest natively.

[mighty carbon]

@mild hamlet by chance, do you happen to know why?

it's like as if Epic decided to make it even more annoying to dev for mobile VR using UE5

[hard relic]

any idea why displaying ES3.1 is darker?

[mighty carbon]

probably bug that will not be fixed 😅

[jovial hamlet]

screenshots would be helpful
but if I had to guess, I'd guess exposure settings

[hard relic]

thank you, i'm capturing screenshot asap

■ If I'm previewing Android ES3.1
· The weird is the first one. (with unsupported HeightFog)
· The second is the right one.

■ If i'm previewing in SM5, Then it's reversed.
· The weird is the first one. This time Brighter, (with unsupported HeightFog)
· The second is the right one, with better contrast.

■ My project:
· I do not have PostProcess Volume.
· Exposure EV100 do nothing.
· It's HDR Disable.
· It's Forward Rendering
· It's Unlit

** Do not look at groud's Color. It's procedural. So each launched game is different.

I think it's exposure too. But Where?

[covert ferry]

Hey guys,
I am using Air link to dev with UE5 but it seems I lose connection to air link each time I take the quest 2 off my head.
is there a way to stop that ?

I think find the "Turn auto-sleep" setting from Quest 2 and change it to longer might help

Hey guys I have a one mesh character except the hands. I want to attach it to the character arm mesh so the work cocurrently. Atm the hands are seperate from the arm. But I want to attach it to the arm. How can I do that?

[thorny rover]

is there somehow a way to use lumen and nanite in vr?

somehow only one image to stream on the glasses and not 2 or so whatever

[hard relic]

Nanite and Lumen are not supported features in VR.

[thorny rover]

yes i know.😅 but is there no workaround?

[hard relic]

Sorry, i do not know any workaround, and i suppose that there is not for this kind of major features.
The only way i can imagine, is running the game on a PC and viewing with a workaround VR display.

[thorny rover]

thank you for your answer

[mighty carbon]

did we suddenly lose all community managers from Epic ? :/

ODH will let you disable the sensor while you're developing.

Hey guys anyone else getting weird offsets with controllers?

I've got an FABRIK body whose hand transforms are linked to my motion controller transforms, but they're weirdly offset

Any clue why this might be happening? The Grab Locations are just scene components attached to the motion controllers

[wild depot]

i had to do some shifting to make everything line up using FABRIK. i think it is just due to the different objects having different relative rotations. These are the settings I used:

i used this super helpful video to help me figure everything out, so i can't really take credit. https://www.youtube.com/watch?v=EKR8ogonD68

[reef cave]

thanks!

[vivid spade]

Still need help with this? Just cracked it myself, seriously tricky IMO

[scarlet mantle]

Hello guys, my team have released a VR plugin for the UE4 which simplifies the development. I want to leave a link here in case if someone is interested. Plugin provides features such as physics base Player Pawn, physically based hands and a lot of interactive objects etc.
Also you can try a free demo. We'll be really grateful for any kind of feedback. 🙏

i'm having trouble getting level streaming to work on my headset (quest 1). it all works perfectly in editor on my computer, but not when packaged on device.

anyone have any experience with that or know if there are nodes that don't work the same on headset?

[clever iron]

I use level streaming on Quest 1, the thing that killed my performance originally was that you have to build the persistent level instead of individual ones

lighting becomes dynamic if you dont

but once you have the map built for lighting it's all good

then it's just about non-blocking level streams and being smart about when you can unload

[chilly pasture]

Text is aliasing alot inside quest, and we dont use stereo, Is there any work around then using stereo.
In our test with stereo, it was taking too much FPS using stereo, am i doing something wrong with stereo.

can someone give me an approach to fix it ?

[flat quarry]

As of ver5.0.3, TAA/TSR does not work in VR view, except VR template. Anyone know the reason for this?

[flat quarry]

yep, I understand. r.TemporalAA.Upsampling 0 solves the problem. Of course I'm trying this deferred.

[sonic lake]

@scarlet mantlelooking really good! Did you test it also on UE5?

[wild depot]

Well I finally fixed my level streaming issue (there was something broken with my blueprint interfaces / sub-level blueprints, so I just tore them all out and made my own system to handle everything) but now my lighting all looks terrible haha.

Going to have to spend some time learning how to do it the right way so it looks half decent (or go for a pseudo flat/unlit/Untitled Goose Game look if I can't figure it out).

[clever iron]

Yeah there's a "workaround" for building lighting by sub-level instead of as one big level, but it's not recommended lmao. I went with a good enough light build for mine since all of the sub levels stream with the same origin. I'm pretty sure we're supposed to be using it to load levels that aren't on top of eachother, which means lighting isn't competing

[scarlet mantle]

We have test it, there are some issues due to the new physics. We'll update to the UE5 version but it might take some time

[maiden trench]

Is it possible to switch between VR and Normal Desktop mode in game without restarting?

[manic tapir]

my ue4 game doesn't allow me to change volume with the volume buttons on the headset.

[sonic lake]

@scarlet mantlethe Chaos Physics solver is based on a different approach than the PhysX solver, so your whole physics may need reworking. Also some "tricks" that worked well with PhysX are no longer supported by Chaos. What are your major issues?

[dusky badger]

I've heard the physics vr problems persist in v5.1 too.

[scarlet mantle]

Yeah, looks like it. There are issues with physics constraints so the doors, drawers and other interactables such as levers etc. behave unexpectable

[sonic lake]

@scarlet mantlea current issue is that constraints are not able to wake up rigid bodies

so the constraint seems to be broken, but actually it is the rigid body which is sleeping and cannot move

you can try disabling sleep globally in the solver and see if that makes any difference

p.chaos.solver.SleepEnabled 0

of course this will affect performances until fixed

[scarlet mantle]

@sonic lake
Yeah, I tried this one
It worked but it doesn't fix all the issues
If I get it right, this is actually an issue which Epic devs going to fix?

[dusky badger]

I dont know if more efficient/equivalent, but I put an event on sleeping to wake again. I am new to UE after a long time off, but could even get a pendulum to work in UE5 with a constraint.

[sonic lake]

If it anyway keeps all the rigid bodies awake, it is like turning off sleep altogether.

[sonic lake]

Yes, they should fix it.

[dusky badger]

Just the character ones, not all.

[tired tree]

Depenetration forces are also very badly set at defaults

[kind vortex]

Can someone help me? I've been trying to set up my oculus quest in unreal 5.0.3 but it cant find my device in the platforms tab. It can be found in other software that uses it though.

[sonic lake]

Do you have ADB installed? Is your Oculus in dev mode?

[hushed laurel]

I'm trying to package my quest 2 game, but I keep getting this error? How can I fix it? UATHelper: Packaging (Android (ASTC)): ERROR: cmd.exe failed with args /c "D:\FingerPongVR\Intermediate\Android\arm64\gradle\rungradle.bat" :app:assembleDebug
PackagingResults: Error: cmd.exe failed with args /c "D:\FingerPongVR\Intermediate\Android\arm64\gradle\rungradle.bat" :app:assembleDebug

[kind vortex]

what is adb? and yes my oculus is in dev mode

[sonic lake]

Android Debug Bridge, is what is used to talk to the device once it is connected to your PC

[kind vortex]

i have android stuido

[sonic lake]

if you open a command prompt and type adb devices you should see the Oculus listed

ok then you should have it. Do they test above.

[kind vortex]

k

here:

C:\Windows\system32>adb devices

• daemon not running; starting now at tcp:5037
• daemon started successfully
  List of devices attached

C:\Windows\system32>

im going to assume that is bad

that it isnt listed?

[sonic lake]

check inside the device

is there any message?

[kind vortex]

nope

its just blank

[sonic lake]

you should see a message in the device saying to authorize USB debugging

adb will first show the device ID and say unauthorized

[kind vortex]

ok

[sonic lake]

then after allowing in the device it will tell authorized

check again the Oculus app on your phone

make sure the device is in dev mode

[kind vortex]

it still says unauthorized

[sonic lake]

but it shows the ID?

[kind vortex]

yeah

[sonic lake]

ok good

now wear the device, there should be a message in it asking to confirm USB Debug

if not, then the device is not in dev mode

[kind vortex]

yeha i clicked allow

[sonic lake]

ok cool

you are good to go

now open Unreal and the Quest will appear there

[kind vortex]

its still not there

[sonic lake]

restart the editor

close completely and restart it

[kind vortex]

ok

its still not there

[sonic lake]

do you have the VR/XR plugins enabled?

[kind vortex]

ill check

yes

its there

it say platforms are writable

[sonic lake]

so you see it now?

good

[kind vortex]

no

i dont see it

[sonic lake]

still no?

[kind vortex]

yeah

[sonic lake]

adb devices is still showing the device and saying authorized?

[kind vortex]

all it says is device

C:\Windows\system32>adb devices
List of devices attached
1WMHHB67HQ1517 device

[sonic lake]

ok

but in Unreal you should see this

[kind vortex]

i see this:

[sonic lake]

did you authorize the Android plugin?

is it all green?

[kind vortex]

yes

thats the one in the backround

[sonic lake]

honestly I am running out of ideas

maybe reboot the Quest

[kind vortex]

me 2 i have two other devices i followed the same tutorial for and it works on there except the other pcs aren't strong enough to use unreal without getting like 1 frame per second butit still shows the quest

ill restart

i still dont see it

after restarting

[sonic lake]

which plugins are turned on?

should be the default ones in the VR project

[kind vortex]

im sorry im very new to unreal where can i find that?

[sonic lake]

if you opened the standard VR template it should be fit for use

they are under Settings -> Plugins

[kind vortex]

i used the template

and i see the android plugins enabled

[sonic lake]

these two

[kind vortex]

yes

they are enabled

[sonic lake]

which Quest do you have?

[kind vortex]

2

[sonic lake]

I am testing with a Quest 1 but it should work in the exact same way

[kind vortex]

yeah

uh i still have my quest one

should i try?

is there anything i need to setup or can i just plugin

[sonic lake]

try it

just to check

[kind vortex]

it still dosent work

[sonic lake]

you have to put it in dev mode from the app

switch it on

[kind vortex]

it is

[sonic lake]

confirm inside

[kind vortex]

ok

[sonic lake]

USB Debug

[kind vortex]

its enabled

[sonic lake]

the new Quest 1 appears in ADB devices?

it says authorized??

[kind vortex]

it says device like the last one did

[sonic lake]

device ID shows?

[kind vortex]

yes

[sonic lake]

a number and authorized

ok

[kind vortex]

C:\Windows\system32>adb devices
List of devices attached
1PASH9ANTE0231 device

[sonic lake]

now close Unreal completely

restart it and create a new VR project

[kind vortex]

ok

should starter content be enabled?

[sonic lake]

you don't need that

[kind vortex]

ok

done

[sonic lake]

now authorize the Android SDK so it is green

[kind vortex]

ok

[sonic lake]

but the device should already show

as Quest (long ID)

[kind vortex]

nothing.

[sonic lake]

ok, then the only thing is to try with another computer

[kind vortex]

ok

[sonic lake]

I don't know what is wrong with yours

ADB seems to work properly so the device is visible

[kind vortex]

would it be possible to use a different version

[sonic lake]

I don't know why Unreal doesn't see it

I assumed you are on UE5

[kind vortex]

yes

[sonic lake]

It should work just fine

[kind vortex]

ok

[sonic lake]

I have the same setup as you

[jovial hamlet]

you could also try setting the android sdk folders in the project settings manually

[kind vortex]

ok im uninstalling and reinstalling unreal and seeing if that helps first

[jovial hamlet]

also just to confirm, did you follow these steps?
https://docs.unrealengine.com/5.0/en-US/how-to-set-up-android-sdk-and-ndk-for-your-unreal-engine-development-environment/

[kind vortex]

i followed a youtube video that did these wxact steps execpt i used android studio 3.5.3

ill trey using 40.

[mortal spire]

whats the difference between the two options for launching on my physical oculus quest?

[kind vortex]

you only have on quest device so i think they will do that same thing.

[kind vortex]

holy shit it worked. uninstalling and reinstalling fixed the issue thank you Marco for helping

[reef cave]

Yo, I read a few people have managed to get full body movement working

Current working on that myself, how did you guys figure out how to lock the HMD to the pawn?

So for instance, when the character gets moved by ingame forces, how do you make the HMD move with them?

[idle osprey]

One problem can also be ADB getting ahold of the port and not letting go. For example, if you have SideQuest, Oculus Developer Hub, Unity, etc...all of those have a copy of ADB. Android Studio also does. If they're not all using the same executable, and you've got any of them running, Unreal will be locked out. At least, that's been my experience. You can point ODH to use the same ADB that Android Studio has, so you can avoid that. As for SideQuest or Unity, just don't run them at the same time.

[idle osprey]

I don't recommend Launching. I've had a lot of trouble with it. Even if you do a "by the book" build, I'll often get the cursed "three dots". I recommend Package.

Anyone else experiencing problems when trying to use OculusVR OpenXR support? It does seem to struggle with SteamVR installed,, but the current problem I'm having is that it picks up motion controllers, but head tracking and stereo isn't working. This is on a project based of the CollabViewer template, and it used to be more reliable in UE4.
EDIT: just checked a fresh CollabViewer project from UE5 and it seems to be working okay.

[trim hemlock]

guys

[chilly pasture]

Is it okay to change pixeldensity to 1.5 or its not okay.
I am trying to make app look sharper, mostly UI. using stereo costing too much FPS.
Using mipMaps for 3dWidgetComponent, seems blurry, this seems the only option right now.
costing us some fps, but not that much , anyone have thoughts about it ?

[jovial hamlet]

shader-based super-sampling in the 3DWidgetComponent material can help a bit with blurring
also try playing with different filtering options and mip biases

Where to learn AR ??

[reef willow]

Turns out the cause of this behavior was that another person edited the BP_BasePawn > Camera Component > Camera Options > Lock to Hmd = false in the project when attempting to change the Character Model.

[reef willow]

Which type of device did you have in mind?

[ruby bronze]

does anyone know a good solution to stop being able to poke your head through walls? im using a capsule which scales with player height (to account for irl crouching) and that collides with the world. it works ok, but doesent "update" consistently

also going underneath a shallow ceiling, then standing up so i wouldnt fit into it means i cant move, but it doesent force me to stay in the confines of a small area

[formal ridge]

camera affects nav perhaps or you can just setup a collision trace channel for the walls and prohibit clipping when called for the camera collision

[late willow]

@reef willow android

[ruby bronze]

ok i have no clue how to do any of that lol. ive only been using ue5 for a few days :/

one thing id rather do, is to stop the hands from phasing through walls. ive managed to attach hands to the controllers, and gave them gesture animations

[formal ridge]

Camera - https://www.youtube.com/watch?v=jMyl5vvi76M
Coverage of collision - https://www.youtube.com/watch?v=bG6V-AAdfLU - 28 mins in

[ruby bronze]

Thanks, i have actually seen all of that 2nd video

i used it to add smooth turn, snap on the right controller and smooth loco on the left with a ui toggle

does spring arm work for vr cam then?

[formal ridge]

I don't generally use spring arms for my vr chars/pawns - the second video at 28 minutes in covers the concept of collision which will help you with walls and objects

[ruby bronze]

Oh thats a different one

i just realised, i saw one from the same channel but it slightly newer i think

ill check it

[ruby bronze]

hmm the biggest issue im having right now (and i dont think was covered in the video) is how to make hands not phase through walls? to have them sort of 'splay' against them if you push your irl hand too far through where a wall would be

im not sure how to implement that. like i need to take the hand meshes out of the parent of the motion controllers, instead updating their position towards where the controllers are?

[neon geyser]

UE5 is not ready for VR

Safer to work with 4.27, it's more stable. Pavlov had to stop support for Quest1 when switching to UE5 because of performance issues

[obsidian blade]

ok so if i was to do vr in unreal engine you think i should work in ue4 as i have been getting a few bugs with vr and unreal 5 while trying it all which have been anoying me

[neon geyser]

I would, yes, less risky. You can still convert to UE5 later when it's more stable

[obsidian blade]

ok it is only becuase i was using unity for vr development but i hate coding and really perfered the blueprint style of unreal engine so i wanted to give it a try and see what i could make

[rocky nexus]

bps are still code, just harder to make syntax error

[obsidian blade]

yea i know but having it in a visual way made it a lot easier for me to develop a flat screen game in unreal as a tester

i am just stuck in a dylemer as i dont know what engine to use

[idle osprey]

Unity now has Visual Scripting, too. They purchased Bolt some time ago and integrated it.

[idle osprey]

Glad it worked for ya. 🙂

[obsidian blade]

Yea I know I am just not sure how well it integrates into vr

[idle osprey]

You won't find a lot of tutorials for it. I think I know of one. Bolt was pretty powerful because it could use reflection to build its nodes. So, it's probably fine. But you'd be on your own if you run in to problems. In Unreal, most tutorials are done in blueprint and if you want to convert them to C++, you can relatively easily.

Another wonderful thing about Unreal is, they don't change the freakin' API every release!

XR Rig -> XR Rig (Action Based) -> XR Origin -> XR Origin (VR) 🤯

[arctic fern]

Making a fast city scene optimized for VR, and working on one building in blender now. Is it better for performance to:
Use a single model with UV textures with 10 or so windows on it and a mask for roughness etc ..or should i just separate the model into different parts like walls and windows to apply materials to separately in UE

[idle osprey]

Not an expert here, but I believe a single mesh is more efficient in most cases. It depends on culling. You can't cull part of a mesh. If the buildings are modular, instanced static meshes are the way to go, I think.

[arctic fern]

Ok thank you @idle osprey

[idle osprey]

I think the smartest thing to do is make modular pieces and import them. You can combine the meshes in UE. https://youtu.be/H0tTjYnzIRs?list=PLAKh_Qeh5kTz4JHEfb8lQKj9xODb2UIx2 was a good video on that.

[arctic fern]

@idle osprey thanks so much

Is there any specific setting I have to change in project settings in order for the quest 2 to be able to tell me where the error occured exactly?

[rocky nexus]

afaik you need a source build for full stacktrace, perhaps debug symbols are enough but i had no luck with that... i dont think bp would crash with out of bounds, so probably c++ if that narrows that down a bit

[crimson sapphire]

I am using a source build already

Im not sure how to enable debug symbols for the quest 2

and I have no c++ code in the game

[reef willow]

Haven't worked much with Tablet AR.
I would recommend looking through the CollabViewer Template and Handheld AR template.
CollabViewer might have its Handheld AR functionality disabled but there is still supporting blueprints.

You would have to make sure the template are installed, then you should be able to create a new project using them.

[chilly pasture]

Thanks i will try this and see if this helps.

Multi Sampling works awesome. Even if i dont use mipmaps, i can see results clearly. with mipmaps, its almost perfect

but i am having some issues at the moment with mipmaps, for 3dWidgetComponent, where size of the 3dWidget Changes afterwards, they get disappeared after a distance, I think i have to re do the mipmaps, each time i update the size of the mipmap.

[timber pawn]

Is anyone aware of a free VR friendly water material tutorial?

[ripe crypt]

Hello all i am trying to detect QR code on HololLens 2 (UE 4.26.2. The QR code gets detected and are being updated.

However when i close the app and restart, even if i do not look at a QR code, OnARTrackedGeometry is being called with older QR codes.

As per Microsoft documentation all QR codes remain active and are updated untill the Hololens is restarted

and they have suggested to use the TimeStamp to discard calls to older QR Codes

I need help understand what is the reference this timestamp is based on, it is a 8 digit number like : 17571616 (this is not from Unix Epoch which should be 10 digit).

[jovial hamlet]

You might need to call RenderTarget->UpdateResourceImmediate(false); every time you redraw the widget, because it doesn't get called by the 3DWidgetComponent. That's the call that regenerates the mips.
Also regenerating mips every frame for multiple render targets might get a bit expensive if you are on Quest native.

[ruby bronze]

hello, im having trouble following this tutorial: https://www.youtube.com/watch?v=E16JFQdiiGk&list=PLbgD2Tk2QUnn2eq6OSXPkD3uW10URi4D3&index=1

im using UE5 instead of 4 which is what he is using on the video, and ive tried to follow his steps exactly up until 8:15 when he tests. my vr hand just sticks to the bottom of where my player capsule is instead of following the physics constraint

my VRPawn parents ^

he is using BP_MotionController which doesent exist in UE5 i think

he claims it still works in 5 but i have no clue how adapt it

[tired tree]

@ruby bronze well they are wrong in one sense, UE5 uses Chaos Physics and it is very buggy in current binary release of the engine

constraints don't wake up sleeping simulating objects with the binary release of ue5

you have to manually wake them up or turn off sleeping as a workaround for now

the constraints applied forces aren't considered towards keeping them active

[ruby bronze]

right.. how do i keep the hand "awake"

i think someone said the 'physics material'?

[tired tree]

there are many other chaos related issues in ue5 though, so much in that you would be better off developing in 4.27 and migrating to ue5 once it is more stable

[ruby bronze]

ok, well for now ill look into keeping the hand awake

[tired tree]

you can bind to their sleeping event and wake all bodies, but what you will be holding with them later will also have the same issue

can totally turn off sleeping in chaos but that has performance impact

p.Chaos.Solver.SleepEnabled 0

[ruby bronze]

is it a major fps loss?

[tired tree]

sleeping is to some extent the least of your worries with chaos though, most physical interactions across the board have issues with constraints and clipping

depends on how many objects are simulating in the scene no longer able to rest, its not a "you lose 10 fps on average" type of thing

[ruby bronze]

ok ill try the command. how do i run that in a play preview?

[tired tree]

`

and type it

[ruby bronze]

ah gotcha

well guess what even with sleeping disable my hand still doesn't move lmao

[tired tree]

if its still not moving then you didn't simulate physics on it

[ruby bronze]

nah thats ticked

[tired tree]

or the constraint isn't actually setup correctly

[ruby bronze]

i mean.. i followed that guys video exactly

i set the constraint up just as he did

is this alright?

if you have something childed under something else, does that mean it will always move exactly with its parent

(im just testing with the right hand btw)

[tired tree]

yes unless its simulated

constraint settings in chaos are also going to be way different if its using stiffness and damping with drives

[ruby bronze]

should i just use 4.2.7 instead?

[tired tree]

@ruby bronze I pretty much said you should yes, 5.1 should be more stable but its very early on and UE5 has some growing pains still

[fathom temple]

Everyone is always after the new "shiny". But what does UE5 give VR devs? Nothing but pain. I think this is a common pattern for new devs. They're chasing the latest bleeding edge, and only getting in to trouble. I really haven't seen much significant change in UE for VR since 4.23. Quest support is about it.

[ember forum]

anyone been able to use ASW with oculus 427 on quest2? I've followed all the steps on their docs but never get ASW frames to pass 0 (I have the ODH tool that shows asw frames + normal frames)

I can use the device output to check asw and it shows that its enabled even, but it never turns on

[chilly pasture]

yeah i am going to do that.

Thanks

[orchid elk]

How do you set the icon and display name of a game packaged to the Oculus Quest 2?

[reef willow]

Maybe Project Settings > Platforms > Android > Icons and Project Settings > Platforms > Android > Icons

[bronze sand]

Hey folks. I've been given the order to change my project from a high end vive project to a portable quest 2 project.
I have never devved for oculus, I'll be going over beginner guides and documentation for quest 2 stuff, but are there any specific pitfalls one might think of for making that swap? All models and materials will be downgraded or flattened, I'm assuming I need to abandon translucency

[dreamy ivy]

Hey, the main thing would be to disable the steam plugin and enable the oculus open XR project if you started with a 4.27 or ue5 project, set up inputs. From there its convert your project to forward shading and begin optimizing everything everywhere.

[rocky nexus]

depending on the project design it will go from bad time to very bad time

[bronze sand]

Appreciate it! Yeah I'm in 5, already have it converted to forward shading.

And @rocky nexus oh yeah. Ohhhh yeah. It's been a bad time this whole time man. But I'm a freelancer so, hey, what can you do

[rocky nexus]

if you never touched mobile dev it would be a good idea to get a vr template working and see what graphics settings it uses

hopefully it is Q2 only, that makes it a bit easier

[bronze sand]

I think I can control that aspect, I'll be sure to dictate Q2 only if that's gonna help me

[rocky nexus]

Q1 is a lot slower and i suspect it will be deprecated by meta october when they reveal the new pro stuff

getting your project to run would be first step, then fix any graphical issues that probably will happen, after that its a lot of optimization most likely

[dreamy ivy]

recommend Q2 also, and make sure to start with a blank template when setting up your android studio sdk and ndk so you know any issues which might pop up are only related to your engine and android settings.

this saves alot of time.

i have a video on how to do all that if you need it. https://youtu.be/nixc8NF_97s also works for 4.27

[marsh crystal]

What’s the best method for doing sequence based or even just level based camera blends when you have vr controllers attached to the player cam? My only 3 solutions have been to attach the camera to the cam in the scene or sequence with a trigger (reattaching and detaching can get tedious) , attach the vr controllers to the player controller right from the start (which works but I’m getting inconsistent results during blends.), or spawn a new set of hands on each camera and kill the old ones.

[rotund badger]

How would i make a turnable knob in vr, I cant find any tutorials or posts on the forums

[sonic lake]

You get a lot of levers and buttons tuts, but no knobs. In any case it is like a lever, just it rotates around a different axis.

My way to approach is to first sense the interaction with the hand, then have the knob rotation follow the hand rotation and finally sense the end of the interaction.

It is basically a link and track mechanism. There are other ways to implement the interaction but this is the one I recommend for simplicity.

[rotund badger]

Oh wow thats super useful thanks :)

[radiant wind]

Using the default openXR plugin, and a nav mesh, my teleport is going through the ceiling and teleporting me up to the 2nd level. Tried everything, can't fix it. Any ideas?

The visual teleport beam is literally being blocked by the collision, but it's still crossing above

[marsh crystal]

Anyone know how it can get the world position of the end of vr controller?

is it just the forward vector of the controller + whatever value you need in front of it?

Oh I think I found it

[marsh crystal]

Is it possible to build a screenspace UI via "add to viewport" that works in both vr and non vr? Currently I have 3d widgets placed just in front of the player camera but I dont want that anymore cause environment meshes can clip and stuff.

[daring pasture]

@marsh crystal not that I'm aware of, but you can make your widget material transparent and disable depth on it to prevent any clipping

[marsh crystal]

I actually didn’t know about that depth thing! I did figure out a way to get a screen space widget where my touch controller is point however. But it is not displaying on both eyes in the hmd. Other devices work great.

[daring pasture]

Yeah screen space widgets wont render in both eyes i believe.
I've always just disabled depth on world widgets since stereo layers are lacking for most cases

[reef willow]

Does anyone know any good tools to auto generate images of motion controller input mappings?

[marsh crystal]

The only other issue I was having with 3D widgets placed in front of the camera were that they were receiving post process effects and made them look ugly

Is there a way to stop that?

[trail shale]

You could easily take an image as a background on an image and make Text Variables that you pass in the controls - (actually there would be two text things, but only one would be variable, the constant text would just be the normal button, like Thumbstick, and the variable text might be "Movement" or "Fire"

[trail shale]

Try to get the location of your collision event - you might need to add a Z offset to your teleport function

or in this case, a negative z offset

[coral dock]

[marsh crystal]

Anyone know why whenever I attach my vr controllers to another camera it inherits my HMD rotation? It happens even if I set Attach Rotation Rules to Relative. It also still happens when I turn off Use Pawn Control Rotation as well. The only way Ive found around it is to make sure the root of the VR Controllers is on a spring arm and that arm has Use Pawn Control Rotation Enabled. (which is weird). But that still doesnt work well. You can see the hands jittering when I rotate my head.

[jade kettle]

Is that flag "Follow HMD" on the camera disabled?

Not sure if that's the right name but it's something in that genre

Hey Guys, On a quest 2 is it possible to have one app open up another, so kind of create a "Launcher" app

[hollow tiger]

When testing the VR test map with my Vive cosmos theres a blue rectangle on the floor and i cant teleport.
Im only able to bring a menu up that says restart or real life?

[hallow knoll]

Which version are you using? This is during VR Preview in Editor yes? Is SteamVR set to the OpenXR runtime?

[hollow tiger]

5.03 and yeah if I preview in VR it’s like a little blue rectangle. I can see the teleport ring, just doesn’t move.

It’s like the initial issue where cosmos bindings aren’t set and I can’t workout where they’ve moved

Oh see steam VR doesn’t open and if I do the preview closes.

That was gonna be my next question

[trail shale]

How would you go to "slow" a VR controller down - I'm sure it involves a tick, I'm trying to tear off tags and I want it to slow down the controller so you don't see it moving much to simulate the resistance of pulling something - I'm not sure how to override the MC tracking

[formal ridge]

There is a tutorial online that is used to create a drag using a scene comp on the object to create the "slow" or "weighted" effect

[trail shale]

thanks - does it involve the motion controller? it's that which has me stumped - because I can't just override the tracking, (otherwise I'd just set a world pos via tick) ideally it would be something like "Get MC Tracking info, divide by 10 )

[formal ridge]

https://www.youtube.com/watch?v=E16JFQdiiGk

[trail shale]

perfect this is exactly what I asked for!!!

[formal ridge]

Yeppers 😄 No worries ^^

[trail shale]

crap - the thing I'm doing is like the one exception to this - these are just little tiny tags - so the resistance wouldn't be physics based would it?

[formal ridge]

hmm

you could apply weight at the range you wish to emulate the latching effect

and then release the weight if pulling continues after that point is reached + continued

it's all about illusions with vr and ar

however you can simulate the movement to trick the mind

[trail shale]

Yeah I'm going to see if I can take some of this - i don't need all the angular limits he has but just getting the weight hooked up and then ending it on end overlap, toss in a sound of paper tearing and it's good to go

[hallow knoll]

Which runtime are you using if SteamVR isn't running?

[trail shale]

is this grab physics restraint on 4.26?

[formal ridge]

oof, not sure I'm on ue5 now a days

[hallow knoll]

@trail shale if this is a one-off and you're not looking to provide a bunch of physics based objects I would just drive the location of your object by interpolating it towards the motioncontroller

[hollow tiger]

Viveport?

[trail shale]

I posted a video - the object is a little tag - should I just hide the MC and spawn in a proxy (I'm doing that away)

[hallow knoll]

Isn't Viveport using SteamVR as the runtime? I've never used Cosmos but all of the Vive/Vive Pro's etc use SteamVR (with an addon)

[hallow knoll]

Yeah, you can't (and shouldn't) override the transform of the motioncontrollers as that's set by the runtime

[trail shale]

I did this once for the headset, to isolate the axis - it worked but did feel very weird

[hollow tiger]

I’d normally agree.
However haven’t used them in a while.

Tonight I had viveport open and completely forgot about steam VR as it always used to open anyway.

Anyway, vive was always open, I’d preview, try open steam and preview would close.
I’d try have steam VR running and it would close when opening preview.

[hollow tiger]

I’m assuming the steam Vr still controls the binding issue which is why it playing up right?

[hallow knoll]

The OpenXR runtime will try to pick the best matching interaction profile if one doesn't exist for the device. We don't have FKeys for Cosmos, so no profile for that is set in the VR Template, but SteamVR should be able to rebind to Cosmos. If not, that's a runtime issue. However, your situation with SteamVR seems sus, but I don't have a Cosmos to test with.

Use this tool to verify (and switch) which OpenXR runtime is set to be active: https://github.com/maluoi/openxr-explorer

[trail shale]

I know I'm interpolating this wrong.... I know these are big numbers - but it either stays at the location or disappears -

trying to think it out - if the MC moves 100 units, I want this item to move maybe 10 of them

just need to convert that to world units

[trail shale]

anyone? I'm still stuck on this and I'm certain it's a problem others can point me in the right direction on

[hallow knoll]

@trail shale Vector Lerp to the rescue

[trail shale]

I'd use this on tick to update the world location of my slowed down mesh?

tick is delta time and interp speed is the % I want, so .5 would be halved movement speed essentially?

[idle osprey]

...I see what you did there. 😉

[tacit quest]

hey, has anyone successfully overridden the virtual keyboard? i want to use my own custom keyboard on all platforms (hololens/vr/windows)

[marsh crystal]

Has anyone successfully got a VR HMD to follow a pre set sequencer camera? I have this sequence animation that works fine without vr but in vr it doesn’t use that view target.

[rocky nexus]

doing that sounds like a great way to make someone sick

[marsh crystal]

It’s very slow

[rocky nexus]

the entire point of hmd is to match users head, moving it directly will probably not work. attaching hmd to something and moving that sounds like something that could work

[sturdy coral]

you might want to look into what they did for showdown; that was matinee but I think it did use a camera within a matinee track

[marsh crystal]

Yeah I'm only wanting to update the location and possibly yaw

[marsh crystal]

Weird I tried to open the showdown project earlier and everything but the matinee sequence was available for me to see. Like the matinee is there in the level and I can click on it but I can’t browse to it cause it doesn’t exist in the content browser

[sturdy coral]

which engine version did you open it in? matinee is gone from some later ones I think but maybe can leave a remnant

[marsh crystal]

4.24

[sturdy coral]

looks like needs to be 4.23 and below

[marsh crystal]

Ohhh ok! Thanks!

[formal ridge]

yeah I do it all the time - did it in the epic megajam this year

but on 5.0.1

[marsh crystal]

Would you be able to help me understand the setup because nothing has worked for me.

[bold spear]

I am new to game development, let alone VR, but I'm diving in. I am trying to develop for my Quest 2 using Unreal on a Macbook Pro with M1 chip. Should I be following the UE5 documentation to develop for Android or UE4.25 documentation which is specific for Quest on Mac? Or Any other path you would recommend?

I've set up the Oculus Motion Controller (L) Thumbstick as an Axis Mapping, which works fine.
Now, when I try and use the Oculus Motion Controller (L) Thumbstick Up as an ACTION Mapping, it gives off no response whatsoever... Anyone any clue how I can resolve this? My menu requires simple action mappings to function

[clever iron]

There’s an option for allowing override that might help, if you click on the input events. I can’t remember which you need to do it on though

[brittle bone]

Im not quite sure I follow... I've got an Input Event in the Project Settings -> Input, that has been set to Oculus Motion Controller (L) Thumbstick Up. But that does nothing. Is there a setting on that screen to magically enable it??

[clever iron]

Sorry I’m not able to provide screenshots at the moment. If you added keyboard event A to a blueprint and then clicked on that event, there are settings to override. If you have that event somewhere else, one always takes precedence over the other so unless you add an override or whatever the primary event consumes the input

I've been working on an updated version of the VR Template and made a short video of the features I've included / built.

I'm using Windows Mixed Reality Plugin for Holographic streaming to Hololens2.
Currently, my application will crash if i execute console command "open MapName" to ln 57 inside WindowsMixedRealityCustomPreset.h ( if (StereoDepthTexture != nullptr) )
How do i maintain holographic streaming on map change?
can i pass -vr -HoloLensRemoting=192.168.1.71 -RemotingBitRate=25000 somwhere in bluerpints?

[tropic kestrel]

Yo how do you peeps typically handle color grading for VR

Seems so infuriating because you color grade it in editor, you put headset on and it looks shat

and every headset seems to have a different Gamut so it can look great on Vive, washed out on Quest

super annoying

[shadow radish]

hey snaps, you can customize the ue4 editor to view what it looks like when processed via vulcan

@tropic kestrel https://www.youtube.com/watch?v=8RGKausR3Bk

[tropic kestrel]

Yooooo thx!

Ah but would this actually work for desktop level rendering to see disparity? I think this just emulates rendering with the vulcan shader options right? I doesn't actually match the color space (and I guess it can't because the Gamut of monitors is usually different)

[jovial hamlet]

there is also some more info on oculus devices specifically here

Hi, would you people advice Unreal 5 for a new sim racer VR project? And if so, why?

[wooden chasm]

if nanite and lumen are working i will give it a try

but as far i know is not working

[lyric swift]

No, those features are not supported in VR

[trail shale]

My collision sphere is a child of the Animated mesh but it is not moving along with the mesh (so when the hand grips, the collision are still in the same position (though they move with the controller like normal) any ideas ?

[solar bobcat]

I'm learning VR dev myself and I can say it's been a real pain in the ass so far to simply pack a project for Oculus 2

don't know about the other devices, but for this specific headset UE5 is a no-go in it's current state of the engine

[rocky nexus]

its a pita on ue4 as well, mobile devices have a lot of hoops to get stuff to run on them

[tired tree]

@trail shale attach it to a socket or bone in its properties

it will follow the animation then

[trail shale]

Thanks, I knew it was something simpler than I was making it out to be

[idle osprey]

I really wouldn't bother with UE5 now for VR. Experiment with it, certainly, but I wouldn't commit to a big project with it yet.

[hushed laurel]

How do I add SteamVR inputs to Ue4? The default Oculus Touch inputs do not work on my quest 2. Some of them work, but the thumbstick axis’s, and a few others just don’t work

btw, I tried a plugin, but it isn't for 4.26

[silk lodge]

by the time you get well along in your project, unreal 5 will probably be better than 4.27 for development.

[spark root]

getting an issue for UE5 trying to build for quest here's the log files

I'm a newbie with ue so bear with me

[sturdy coral]

Manifest merger failed : uses-sdk:minSdkVersion 23 cannot be smaller than version 28 declared in library [:UltraleapTrackingServiceBinder:] C:\Users\eknow.gradle\caches

remove the Ultraleap plugin

or disable for android

[spark root]

K thanks @sturdy coral Also do you have a suggestion as a replacement for ultraleap as a hand tracker?

[sturdy coral]

Doesn't quest have something separate for hand tracking?

you just need to disable it for the quest build somehow, or up your min sdk if possible

[spark root]

idk im extremely new like first project new

[sturdy coral]

just turn it off then esp. if you don't own a leap motion/ultraleap device

click on plugins... and search ultraleap

[spark root]

yeah I already turned it off

just need a replacement but Ill look for the quest version thank you

[sturdy coral]

just try and get a build going first and then you can try handtracking if you need it, I don't know if they have their own plugin or if it goes through the openxr hand tracking plugin

(you can run ultraleap through openxr hand tracking too with some work and a driver from them)

[spark root]

ok sweet

[sturdy coral]

I doubt it works on quest though

[spark root]

then ill just find a way later thanks though still lol

[sturdy coral]

np, some one else can probably tell you how to get oculus's handtracking working

I've recently done some android stuff but not quest

and I've done ultraleap on PC through the openxr driver

[lyric swift]

Can you explain a bit why?

[wooden chasm]

Hi i'm developing apps for standalone VR devices, is there some examples of photorealism or project settings to adquire the most realistic viewing? pico neo 3

[wooden chasm]

🙃 🙃 🙃 🙃 🙃 🙃

[turbid wyvern]

hey everyone ! is there something similar to UltimateXR for unreal engine ? To facilitate hand poses greatly ? https://www.ultimatexr.io/

[rotund ruin]

Anyone know how i add NavMeshBoundsVolume in AR? say i want an AI to randomly walk around but it needs a Navmesh to walk around right?

So if i track the plane and then put out my AI i would want an Navmeshboundvolume to be put at the place the AI is placed so the Blueprint will make it randomly walk around there

[idle osprey]

Mostly because there's nothing special about UE5 for VR devs right now. The VR Template is basically the same. And UE5 is a 5.0 release, while UE4 is a 4.27 release. It's going to be more stable, more predictable. The new shiny thing is not always the best thing to work with -- especially if you're new to UE. If there's not currently and features in the engine you can take advantage of yet, why select the one that is potentially less stable? Will you know when it's your bug vs a bug in the engine? When I was first starting, some very wise people in this channel told me to never work with a x.0 release. Instead, wait for a .2 or a .3 before upgrading. UE5.0 is that far along, yes, but it still comes back to -- is there anything specific in UE5 I need for VR? No, not yet. So why upgrade? 5.1 may be a completely different story, so I'm waiting for that one.

[austere fern]

whats up, im trying to light a scene with a stationary light in vr, but my shadows are only working in the left eye, similar to what happens with translucencies. Anyone knows how to sort this out?

do dynamic shadows work in vr?

[idle osprey]

Depends on the platform/hardware.
