HMDPluginPriority is only used if the OculusVR and/or SteamVR plugins are enabled. If they're only running OpenXR and OculusOpenXR then it's only going to be OpenXR.

[limpid widget]

Oh, interesting, thanks for the info

[hallow knoll]

Np, and that priority list was removed when we removed the OculusVR and SteamVR plugins

[limpid widget]

In terms of other plugins, like PicoOpenXR and MetaXR, how does it decide which to use?

[hallow knoll]

It will use all of the plugins that are enabled, but the OpenXR extensions that are included in the plugins are enabled if the runtime supports them

PICO's runtime(s) actually supports some of Meta's vendor extensions

Not sure if they have support for them in their UE plugin though 🤔

If not yet, they most likely will

[limpid widget]

ah alright, I was just curious, because I also have all of them enabled all the time and I can use the same apk for pico & quest and also the same configuration for windows & psvr2. Kinda like it that it's like that, when packaging I don't need different targets and can just use the same thing.

[hallow knoll]

That's the whole point of OpenXR and Khronos way of developing open standards. I'm super glad to hear it's working for you!

In a (can't come soon enough)-future all runtimes should also support the same OpenXR Android loader, at which point you should be able to deploy an .apk that was only developed for Meta Quest to a PICO or HTC HMD, and vice versa 🙌

[neon geyser]

I guess it works with 5.3, can't upgrade, we are using 4.27

[rocky nexus]

could be anything, build dev mode and check logcat for errors

[rocky nexus]

sure, its an android device

[latent belfry]

Hello, does anyone have a good VR tutorial to make a VR Vignnette to reduce motion sickness in people? Like the one they use in among us vr

Like this, where the whole world is encapsulated in a circle, and at its sides there's like another world that doesn't move

[novel gorge]

Put a plate mesh with a material in front of the character's camera? 😉

[atomic drum]

I was writing a step-by-step for a friend for setting up Quest 2 in UE5.2.1, maybe useful for people starting out: https://dev.epicgames.com/community/learning/tutorials/1GxB/unreal-engine-5-2-1-for-meta-quest-vr

[latent belfry]

But the plate mesh will show what? the world? Cause I believe the problem relies in making the extra-cube-painted world in the back

[limpid widget]

what I usually do is I connect the device to the pc, use the Meta Quest Developer Hub and there you can see a live log of the device in a nice window, where you can also do search etc of it.
Then once you start the program, red errors should pop up telling you about any issue

[limpid widget]

It's probably just a plane mesh in front of the character's camera, where the material has a circle in the center masked so that it's alpha 0, and besides that it's just a regular texture

[limpid widget]

why do you get the metaxr plugin from the meta xr simulator instead of the official page for the plugin? (https://developer.oculus.com/downloads/package/unreal-engine-5-integration/)

[atomic drum]

The plugin is part of the Meta Branch of UE5.2.1, the Simulator is for visualization when not using a headset

But it does look like they posted that yesterday, 😂 I’ll give it a try 👍

[novel gorge]

The plane shows this (with a translucent gradient to the center). Maybe it shouldn't be a plane but a ring so that you don't need translucency in the center of the ring, because it's very expensive for the GPU.

I mean this.

Or vice versa, I don't know yet 😄 I think you know what I mean.

[hushed shuttle]

hi there did you ever have an issue where when you tried to grab an object with a grab component it disapeared the first few times? thanks

[sonic lake]

@hushed shuttleit's probably not "disappearing" but flying off due to collisions with the hand/motion controller. Make sure it has the same collision setup as the other grabbable objects which are not flying off.

[hushed shuttle]

thanks for oyur answer

i actually solved it by replacing it with a grabable cube

but i still get this crazy error

when i test with the vr headset
i can test once in the viewport with the headset one but the second time i open the window it crashes and give this error

[sonic lake]

@hushed shuttlehard to tell what the problem is since you don't have any debug symbol loaded. You can try to clean up your project and see if that solves it. Close the editor. First make a full backup copy of your project then delete all folders except Content, Config, Plugins, Source and the uproject file. Finally open the project again in the editor.

[hushed shuttle]

ok thanks a lot ! i'll do that
Yeah the error is really not helping..

[latent belfry]

thank you! I'll try that and see how it goes

[grand kayak]

i have problems with my rendering in vr...
on one eye, it does show things just like shadow in this beautiful blue

[rustic plinth]

anyone replace the vr hands with a metahuman ?

to have full body IK

[atomic drum]

Also heres one for 5.3.2: https://dev.epicgames.com/community/learning/tutorials/3Vx6/unreal-engine-5-3-2-for-meta-quest-vr

[real needle]

So I've been messing with Heterogenous Volumes lately, but they only render in one eye. I know there's a name for this, I see it a lot, but I can't remember. Anyone willing to enlighten me? I assume that I can rewrite the rendering code to make it work, which does sound difficult, but I've heard of it being done, am I mistaken?

[real needle]

I'm assuming i'd do this, but for UE5 instead of Unity?

[novel gorge]

Thanks, is there any good reason why these methods are protected?

[neon geyser]

This is regression introduced by the last Oculus app update

https://communityforums.atmeta.com/t5/Unreal-VR-Development/UE5-Crashes-when-playing-in-editor/td-p/1101711

@hushed shuttle I don't think you'll be able to fix this issue, this is on Meta side. There are workaround like using SteamVR or the Oculus fork of Unreal Engine worked for me

btw don't hesitate to post on Meta forum, the more people post, the more chance they fix it rapidly

this issue is a nightmare

someone also fixed it using UE5.3 I think

[sonic lake]

@neon geyserthanks for the info. Seems to affect only the Quest 2 though. I did quite some VR development today on 4.27.2 / Quest 3 and no crashes. Would have to try with the Quest 2.

[neon geyser]

Yes it seems very specific (Quest 2 / UE27, 5.1, 5.2 / only with the epic launcher UE)

also make sure to try 2 times, the first time it always works fine

[sonic lake]

@neon geyserBeing an engine crash the only way to seriously debug it would be to build from source and trace back from the exception

Does it only happen with the launcher version of the engine though?

[neon geyser]

I didn't really had the time to investigate much, had to find a quick solution and what has worked so far for me was to switch to 4.27 Meta fork with Oculus VR plugin

[neon geyser]

yeah but i have a very important project i need to finish and i tried to put in 5.3 but it just doesn't want to package for an other issue ahah i'm stuck between isssues

[knotty wyvern]

Hey guys, my character in VR sinks into the floor when I start the application. Is there a reason for this?

It sinks halfway into the floor

[charred drum]

Diving back into UE + VR with 5.3.2 and am having some odd performance with the built-in Blueprint Virtual Reality Template. Framerate is great, but it's laggy, both in-editor VR Preview, and packaged using the shipping profile. Doesn't seem to matter what framerate or resolution I set, and I've tried both AirLink and Virtual Deskop (with SteamVR and VDXR) with Quest 3. Don't have this issue in any other VR apps.

[charred drum]

It's not just laggy, it's somehow extra jittery, like the micro-movements that your head makes when you think you're holding still are being magnified. Yet when you turn your head, the view does end up pointing in the correct direction.

Hand tracking is fine though, feels quite responsive.

Created a new level in the project, threw in a few cubes and a light, and still has the same issue.

[sonic lake]

@charred drumThe standard VR Template works fine for me on 5.3.2 / Oculus 2.

Can try the Quest 3 as well.

Zero issues also with the Quest 3.

[vivid spade]

I didnt do metahuman but did setup and am using full body IK

[rustic plinth]

any tutorial on how to do it by any chance ? 🙂

[vivid spade]

No there is nothing good at all and I'm not making one lol

can easily share the basics of the setup though if you want, whats your sticking point on setting up full body IK?

[rustic plinth]

learning away bit by bit basically , pretty new to making ik rig in ue tho

would you say its a fairly advanced to do ?

like if i put in a ik rig from blender would there be a fair amount to change to make it vr compatible

[vivid spade]

Its stupidly simple

I prefer IK rig over Control rig, both are solutions though

Create a full body IK, add in goals for head and hands

On tick, get the location of the controllers and camera, set target for head and hands to be the camera /controller locations

My feet goals are for foot placement on uneven terrain and I created neck & shoulder goals and set them to a location relative to the camera to ensure they stay pinned behind the camera and dont get in the way

Heres an old vid of this (bit unpolished at the time) in action:
https://www.youtube.com/watch?v=y1jSCJ4w8iQ

And heres the animation blueprint where I use a state machine to determine if the base animation is a run/walk/prone/jump/whatever animation then the IK takes that reference pose and ensures the head/hands/feet are where they should be based on camera/controller inputs and some line tracing for feet

[rustic plinth]

Found the issue, having OpenXR Toolkit enabled is causing it.

i cant deploy an empty project to the quest 3, i just get a generic error, platform android is not a valid platform.... can i link my setup and you give me a hand?

presumably i have a wrong version somewhere, but i followed the setup and it is incomplete. this is my SDKs

vs2022 has these, not sure if relevant...

as in i think it was on the meta dev area. was last week, forgot

[real needle]

how is this a fix

just delete the user variable??

[atomic drum]

Yes, delete it. It’s so the SetupAndroid.bat will run without errors (you can put the path back later if you like). I just don’t like editing .bat files 🙂

JAVA_HOME has been deprecated for awhile, but some apps still use it (I’m looking at you Minecraft) 😂

[olive ferry]

Tried that yesterday but app crashes when using MetaXR plugin + OpenXR
When disabling Meta or OpenXR The app works just fine

[sand abyss]

question. how are firearms usually made in vr? is it a combination of static meshes and components or similar to 2d where its a skeletal mesh and only have things like charging handles and other grippables be their own meshes for components? im not sure if theres some kind of standardish workflow for them

[tranquil geode]

Does anyone have good resources for starting in vr development?

@tranquil geodelike this? https://www.youtube.com/watch?v=vT1T2unF8EI&pp=ygUedW5yZWFsIGVuZ2luZSA1IHZyIGRldmVsb3BtZW50

[tranquil geode]

Yes sir, I have watched that one. I’m looking for more info on building general vr game mechanics. Such as how to make grab able components

[sonic lake]

@tranquil geodedid you take some time to analyse the VR Template which ships with the engine? That has the basic logic you are looking for.

Including grabbable components, basic weapons. teleportation, spectator view, etc. All basic elements of a VR experience.

[atomic drum]

Make sure to set: General/XR API: Epic Native OpenXR with Oculus vendor extensions. It’s in Project Settings for the Meta XR plugin.

[limpid widget]

I have to correct myself. I updated to 5.2.1 and now MetaXR Plugin & PicoForOpenXR does not work together anymore, as both implement the same function.

as the pico dev told me, it's known & cannot be avoided, so I'm using seperate targets for this:

[olive ferry]

I'll try that now ! Thank you

[olive ferry]

This time app launch perfect but the PassThrough is lost as MetaXR isn't prioritize. thank for the tip 👍

[rocky nexus]

how did you setup diff targets? just build files with conditional plugins or something fancier?

Hello.
I am studying Unreal 5 in Korea.
I bought Meta Quest 3 for the first time in my life because I wanted to create vr content.
The Oculus program perfectly connected the computer.
When I tried to run vr preview mode in Unreal Editor, the button was disabled, so I couldn't run vr preview mode as desired.
May I know why Meta Quest 3 and Unreal Engine Editor don't connect in vr preview mode?

[limpid widget]

Just add more target files and unreal will detect those. Later I can post my example to avoid the "unreal detected multiple game targets" error, but there are also youtube Videos about that

[real needle]

Hey @autumn matrix, I heard you have access to bleeding edge VR features that are going to be deployed on 5.4, i didn't want to shoot you a DM unprovoked, but any chance you can share how you did so?

[limpid widget]

Connect your quest to your pc, make sure the oculus xr runtime is active in the oculus app on windows, afterwards start unreal

[limpid widget]

Is that now the way to go instead of the other option?

[atomic drum]

Dunno, it was the only option that worked 🤣, also the tooltip text says it’s the way Unreal and Meta heading.

Does dynamic resolution and the other features by meta still work with that?

Would the Quest 2/3 struggle with "Simulate Physics" in their games?

[bronze holly]

Angry Birds VR relies heavily on Physics Sim for the tower blocks. so I guess is just a matter of how you balance the resources you need for your game.

the basic Unreal VR Template also has a few Physics Simulated blocks. so to answer your questions, I don't think it would struggle any more than a phone would.

I have the Vive connected to my computer via USB. after watching a tutorial i had the impression that it should work out of the box but it doesn't. my SteamVR Home just get's super laggy when I open the Unreal VR template and at some point Unreal just shuts down. It's also not showing any error log. Can anyone help?

I really don't think your headset should be overheating that much...

What sensors are you using?

Vive Trackers have pogo pins you can wire up

[royal thorn]

Hi ! Sorry, what are the pogo pins ? Also do you recommend any specific steps for setting up the HMD? Like in oculus I have to launch the link from inside the head set? Do I need also to “maybe” enable specific plugins?

It's those small metal things on the bottom, you can connect buttons to them and they can function the same as certain controls

Anyone working with the Meta plugin for 5.3 please note the weird requirement that you have to turn off OpenXR to use VR Preview 🫣

[neon geyser]

oh so it was on purpose. VR Preview crash since the previous oculus app update

anyone using 4.27 now needs to use UE source Meta fork to use VR preview..

[rare tulip]

I've been enabling the plugin only for android builds and then disabling it again to do any work because I'm very grumpy and my index is more comfy than my quest haha.

[weary pulsar]

i've had this issue and the workaround for me was to create a new project and migrate source code/content

I'm having an issue with standalone meta quest 2. Both XR APIs have significant issues of their own and I'm not sure what's causing it. When I use OculusOVR Plugin + OpenXR backend I get an infinite loading screen with the splash screen and my game will not load. When I use Epic Native OpenXR with Oculus vendor extenions my game loads just fine, but my motion controllers are unresponsive. Is anyone here able to point me in the right direction in solving this issue?

this issue really bugs me because my game did work in the past with the OculusOVR plugin, but it just died on me and I'm not sure what caused that

[real needle]

Is there a auto leg IK solution that anyone knows of, or does anyone have any resources I can use to make one? I haven't worked on mine in a while, but it was all over the place

[rare tulip]

Anyone else having trouble getting the VRNotifications component's VR Controller Recentered / HMD Recentered delegates to work on Quest 2? I'm on 5.3, MetaXR and OpenXR plugins enabled, MetaXR is using Epic Native OpenXR with Oculus Vendor Extensions. Both the recenter events are hooked into my recenter function (since some threads said that HMD recenter works in VR preview while only Controller recenter works on packaged builds). I've tried with VR Tracking origin set to both Floor and Stage in the VRPawn.
Been digging through quite a few threads and apparently this was fixed in 5.2. But no luck for me in 5.3.

[rustic plinth]

how do you do this part? 😄

doesnt seem to have the goal positions under the ik rig

[tranquil geode]

does anyone have a good recourse to for making custom snapping to weapon handles? im having trouble figuring it out

[rare tulip]

The VRTemplate has snap-grip to the gun handle using the template's custom actor component for gripping. I'd say take a look at how that's set up, it's very good.

[tranquil geode]

Yes I’m using the grab component on my model. But I’d like to make the grip on the hand a different shape. Am I able to change the grip animation for separate objects?

[tranquil geode]

is there a best practice for adding recoil to a gun in vr? Ive seen people do a good system by adding rotation to the bones in the third person template. But what is the best way to do it in the openXR?

[vivid spade]

So go into the IK rig, and for each goal in the details section, you have checkboxes that indicate "expose position" and "expose rotation"

Hey all, im trying to make a splash screen at the start of the screen, however the solution here: https://docs.unrealengine.com/5.3/en-US/using-splash-screens-for-the-oculus-rift-in-unreal-engine/
does not seem to work. anyone have any tips on how to accomplish this?

[drowsy lotus]

Hey, I asked on #mobile but I guess virtual reality is more appropriate for this

Has anyone here ever made an application that displays media that's stored in /sdcard?

Rather than from a .mp4 file stored in the packaged application?

It's quite odd how little information there is on such a simple and versatile feature

[hallow knoll]

The VR preview crash issue has been identified by Meta and they found a fix that'll go out with one of their updates

Oh glad to hear it, thanks for the update

Anyone finding a 5.2 project that ran builds fine in VR no longer opens in VR as a 5.3 build, even with -vr as a launch parameter ?

[limber mortar]

Anyone recommend an VR framework already created for Unreal? I'm slowly transitionning between unity and Unreal and if there is an Unreal VR framework that already exist that work well I might as well just do that haha

[rocky nexus]

https://github.com/mordentral/VRExpansionPlugin perhaps, there are some paid ones as well i think

[limber mortar]

Thanks! I will look for it. Have you use it before? I saw it but I don't have anyone that I know using it

[rocky nexus]

i am using it

[dense geode]

Has anyone encountered Passthrough only working the first time you do VR preview and after that it's black?

[mighty carbon]

I updated my 5.2 Meta project to 5.3 Meta (VRE) and hands are now rotated differently

any idea how to fix ?

[neon geyser]

controller pose alignment setting that changed?

this is from 4.27, so no idea if this setting is actually similar in MetaXr plugin

[dreamy ivy]

any chance your keeping the headset on your head when pressing play in editor. If so, take it off wait for the play in editor window to open and then put it on.

[dreamy ivy]

does anyone know why unreal cant communicate with Oculus for some reason. This was all working perfectly fine last week and now there is nothing. Event tried with diffrent engine versions.

hands with all the Developer Runtime features in Oculus desktop. disabling it makes it go away but it's needed.

[cerulean lichen]

Do Haptic Feedback Sound Waves work with Meta Quest controllers? I've created an asset and selected a soundwave as input, but using "Play Haptic Effect" using the haptic soundwave asset gives no feedback through the controller, whereas it works fine using a Haptic Feedback Curve

[quiet swan]

I dont know if I am alone in this but my VR project that worked perfectly in unreal 4.27.2 is having serious issues in unreal 5 (5.3.2) many crashes, only reason I came to 5 is because my EOS system stoped working for multipler in 4.27.2 because they dont offer support for "old enginines"

has anyone faced these issues?

[mighty carbon]

nah, there was a bug in VRE.. The author already fixed it a few hours ago. Will be testing after work, again.

[dense geode]

Thank you! Will try this 🙏🏻

[quiet swan]

What was the vRE bug?

[crisp scarab]

Not sure if this is the right channel to ask this, but is anyone using FSR2 with VR? I'm seeing some significant quality issues that aren't covered by the guides on GPUOpen and am wondering if anyone is seeing similar, or has any tips or tricks about what I can do about them. TL;DR version: visual quality is more or less fine so long as the headset isn't moving, even if the camera itself is moving via artificial locomotion, but as soon as the headset moves everything gets real messy real quick. Best I can tell it seems like headset movement isn't included in the velocity pass that FSR2 uses. TSR works fine, but also has a massive frametime hit that FSR2 doesn't.

[quiet swan]

is everyone really on 5.3 in VR?

[sonic kindle]

Hi, has anyone experienced lightmass failing to bake in the 5.2 meta branch (build from source)?
Any help is highly appreciated! 🙇‍♂️

Error message:
Unreal Lightmass executable is outdated. Recompile UnrealLightmass project with Development configuration in Visual Studio.

[limpid widget]

I am on 5.2.1 epic source and it runs fine on all platforms so far

[chilly pasture]

Build LightMass separately

1. Open UE5.sln file.
2. Find LightMass in Solution Explorer, Right Click on LightMass - > Build. Should work after that

[foggy brook]

totally wild:
we upgraded a 5.2 project to 5.3, and all of the sudden when packaging it it wouldn't open in VR.
we tried everything to identify the issue.
the solution? get it out of github.
yes, that's right, if we copy the entire directory (minus .git) to another location and build, VR works. But make a build from the GitHub directory? VR doesn't work.

[chilly pasture]

usually if it is not starting in VR, you need to setthe device correctly and start in vr should be enabled

[plain fossil]

Does anyone have experience on Lumen reflection artifacts on translucent objects on VR . It all works beautifully now with ue 5.3 but I have having some artifacting on glass objects.

[olive ferry]

Did you managed to get it working with OpenXR + MetaXR with that fix ?

[dense geode]

It works! Thank you very much ❤️

[sonic kindle]

Thank you!! This would be the way. However, after re-building the UnrealLightmass the error persists.
Could it be that adding the GPU Lightmass plugin messes up this engine branch?
Even if so, disabeling GPU Lightmass and rebuilding Lightmass from source does not fix anything. I reckon I'll try building the entire engine (this time the new 5.3 oculus version) from scratch again and see if I get any further. 🙂

[mighty carbon]

5.3.x was suppose to be a chosen release, so to speak

[quiet swan]

here is my last hal311 oldvalue-newvalue crash

how do we even figure out what is causing it? I mean, we are here....on the discord of the epic studio who makes this engine and its just going to stay broken?

at @mighty carbon is there anyway to figure out how to fix it? How can anyone even release a game on UE5 like this? How?

[mighty carbon]

@hallow knoll ^^

[foggy brook]

Yes! It works fine now. OpenXR still can’t be enabled when playing in editor but everything works with everything enabled (including OpenXR and MetaXR) in packaged builds

[foggy brook]

High quality translucent reflections don’t currently work properly in both eyes… but maybe you’re describing something different. Screenshot?

Anyone know how long it takes for a submitted VR game to be published on the Epic Games Store? I’ll also ask in another channel but curious if it takes longer for VR vs a normal game

Hey anyone experienced issues with deferred shading on the oculus quest 2 leading to a flickering on only one eye? Works fine using forward shading. Only when switching to deferred shading since I wanna use Nanite

[hallow knoll]

Can you reproduce this in Vanilla UE 5.3? If so, please provide repro steps

[plain fossil]

I cant get my hands on to it atm. In my case its having a green pixelated mess where there is reflections of translucent object or multiple layers of glass. I know it doesnt sound really optimized :D. Single plain glass surfaces are perfect and clean. works super beautifull and doesnt kill the perf. FINALLY can create some amazing stuff for vr

now when I think of it I believe it is lumen reflection issue. but I am also rocking dlss 3.5 so could be combination of those.

[hallow knoll]

Doesn't look like it can be reproduced in a new project. Have you tried removing intermediate and all previous binaries before packaging?

[mighty carbon]

hmm.. no, but I will try doing so and will report back

[rocky nexus]

you are not using either on quest

[hallow knoll]

You can't use Nanite on mobile platforms (yet), but you can use our Mobile Deferred renderer on Quest. However, I've only tested it briefly and we have some work to do to hit our performance targets so it's not a path I'd recommend.

[foggy brook]

restart computer? try swapping openxr runtimes (oculus / steamvr) and see if the same thing happens? what about in a build?

[quiet swan]

yeah it looks nice, but I dont understand how they arent crashing like crazy

[vivid spade]

Build failing with an unknown error so I'm scrapping that right now and just focusing on getting standalone execution working.

[quiet swan]

because when I wave my gun with a beam now, it lags like crazy

[vivid spade]

So I use steamVR, can I swap to occulus runtime with my valve index? not sure if thats possible

[quiet swan]

also my headset has some kind of motion sickness bug where it now jiggles back and forth

[quiet swan]

can nanite cause VR issues?

what about lumen?

[foggy brook]

ah right, no you can't use oculus with a non-oculus headset

[foggy brook]

they are expensive features, as is being in deferred rendering path, so yea that can definitely slow things down

has anyone with a Meta Quest Pro gotten face or eye tracking to work in their Unreal Engine 5.3 plugin ?

[mighty carbon]

nah, UE5.3.0 is trash, sorry to say that

@hallow knoll so, after deleting Saved and Intermediate, I don't see the same error in the log, but the game still doesn't work

crazy thing is that if I press this to run the game from the Editor - it runs!

standalone build - crashes

[quiet swan]

@mighty carbon do you still have the hal311 crash? I do to and Im going back to UE4

that hal311 crash has been on UE5 since it was born and they arent fixing it

@mighty carbon what c++ plugins are you using?

maybe we are using the same one causing the same crash...

[mighty carbon]

no, I don't have it anymore

still get a crash though

now it's a crash without any error report :/

[wraith gyro]

Alright thanks 🤝

[foggy brook]

UPDATE! Confirmed that the MetaXR 5.3 plugin a) breaks face/eye tracking over Link and b) will not package correctly if it's using .git (you won't be able to enter VR)

The fix (really workaround) is you have to use the MetaXR fork of Unreal Engine 5.3. Then those problems all go away.

And before you ask, yes, I tried packaging up the version of the 5.3 plugin specifically from the fork to see if it was different than the one on their download page, but no, it produces the same problems.

[vast eagle]

hey all, I have a splash screen for my loading screen, but when i hide tghe loading screen, my own stereolayer i use for some ui is no longer visible. Is there any way to prevent this from happening?

Yep, using it

[foggy brook]

Sorry I’m only using Quest Pro

ok, lemme correct my statement - 5.3.0 Meta fork is trash

if I use OVROpenXR - everything works, but if I use Epic's Native OpenXR, I get a crash.

Android Studio 4.0

found something?

[neon geyser]

I'm getting an unknown error with no log..

[mighty carbon]

scroll up, maybe there is more

[quiet swan]

Do a search for error

[neon geyser]

yes that was the problem, the error was not flagged as error, so when searching for errors could not find anything 😅

I fixed it, now I got a new one

but I noticed that 5.3.2 require some more specific changes regarding Android studio version and sdks

Found a forum post saying I should install jdk 17

@mighty carbon if I read correctly, you use the software occlusion culling made from FastTravelGames?

[mighty carbon]

switch to JDK-17 vs JRE 1.8.x

[neon geyser]

alright, because I'm porting from ue4 to ue5 and we heavily depend on occlusion culling

is it good?

[neon geyser]

yes it worked just now, build ended

[mighty carbon]

yeah, FTG's software occlusion culling is tested in the field - their new Vampire Masquerade game for Quest 2/3 is UE5 and uses that plugin

[neon geyser]

cool, i'll try that now

spoke too fast, it build but I got the three dot of death

Thanks.

[neon geyser]

is there a way to use the epic engine but 5.3.0? it only shows 5.3.2, the second option is 5.2.1

that must be my issue

[mighty carbon]

You could always download source and build whatever version you want

[neon geyser]

yeah but I also have artists working on the project, quite a mess to make them work on source version

i guess i'll have to wait

[mighty carbon]

[dreamy ivy]

I made a video showing how to fix this. and just uploaded it.
https://youtu.be/k7DKfeeomr0

[exotic pewter]

So, after some thinking, I realize there's a common mechanic I see in VR/AR games, that I truthfully have no idea how to create - for anyone who's played BAM, you have the ability (at least in AR) to size up/down the arena, and move it around. However, it seems more like it's just changing the render size, rather than effecting any physical properties of anything. Pavlov has a similar mechanic when you're spectating a game, although my guess in their case is that they are scaling the camera rather than the actual map. Anyone know how to properly achieve this effect?

[dreamy ivy]

There is a variable in world settings which you can modify to do this, I can't remember the name of the top of my head. But you can use the distance between the controllers to add and subtract from the scale variable. Then make a flying character and use the motion controller position to where you want to move. Similar to a climbing system but your not using a surface.

[exotic pewter]

Interseting, thanks ill have to look

[neon geyser]

yes I was able to fix that issue, I dont have any errors anymore but still only a black screen when building for Quest

I tried on 5.3.2 though

[sturdy coral]

https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Input/HeadMountedDisplay/SetWorldtoMetersScale/

that should scale the world up and down and do the correct IPD adjustment to scale it along with headmovement

[dreamy ivy]

What number are your ndk set too. Both should be set to 32. I show it in this video for the ones to set in project settings.

https://youtu.be/CRDDgFKuPh8

[neon geyser]

Yes I tried with 32 for both

[quiet swan]

I was able to pack my quest 2 with the newest version of android studio using a different install location

I was able to get it to work but now it’s opening up as an android game

[sudden moat]

This is happening to me on 5.2 as well? No clue what to do

[rocky nexus]

im still on 4.27.2, everything works as expected, pure bliss and happiness! and engine crash here and there

[mighty carbon]

If you build for Quest primarily- use Meta fork

[neon geyser]

btw this has been tested on 5.3.2? or just 5.3.0?

Did you had a successful Quest build with 5.3.2?

[tranquil geode]

Can you apply a rotation to the controller on trigger pull to simulate recoil for a gun model? Idk the best way to call that out in blueprints

[ashen dome]

Question, Anyone got both a Quest 3 and a Quest Pro, and which one do you find better for VR development,

[tired tree]

@tranquil geode just adjust the relative transform of the gun that is attached

[tranquil geode]

Does a relative transform let the hand move with the model?

[tired tree]

@tranquil geode if its attached to it yes

you can attach the weapon to the motion controller

[tranquil geode]

Nice! Thank you so much man!

[granite eagle]

Can anyone recommend some VR marketplace stuff? Mostly looking for a general system that would be good for handling RPG type gameplay.

[glass yoke]

Turn off motion blur right?

[mighty carbon]

What does logcat tell you?

[foggy brook]

You have to pull your project out of a directory with a .git folder. Meta also broke face and eye tracking with the 5.3 plug in. We’ve unfortunately moved to their 5.3 fork where everything is working

[foggy brook]

If you care about face/eye tracking or comfort, go Meta Quest Pro, otherwise everything on 3 is better

[neon geyser]

I couldn't get anything meaningful from the logcat. I reverted back to 4.27 for now, I'll wait the meta xr plugin for 5.3.2 and try again

[dreamy ivy]

This was all done with 5.3.2

[neon geyser]

ok i'll give it another try

[vivid spade]

Hey guys so I just wanted high level opinions on wall running in VR

https://www.youtube.com/watch?v=YdwOVpoN9C0

I've hit an issue I just cant quite solve:
When wall running around a curve, I feel that I MUST orient the camera to adjust for the curve. So as you wall run around a 45 degree angle, your player/camera also rotates 45 degrees to keep you facing perpendicular to the wall. Otherwise you'd hit a corner and suddenly you're just facing directly into the wall.

The problem is:

• Smooth turning triggers insane motion sickness for me and I've got some serious VR legs. It just doesn't feel like a viable option.
• Snap turning to adjust for the change in wall run direction doesn't make me sick in the slightest, but its incredibly disorienting in that its hard to keep track of where I am, whats going on in the heat of the moment when the wall run "takes over" my camera in order to rotate it around a curve.

I really cant find a good solution for wall running around curves in VR, nothing I've tried so far feels quite right when it comes to solving "What to do with the camera when the player wall runs around a corner and the wall run direction has now changed"

[sturdy coral]

How does it feel with just rotating your head to rotate (wireless + swivel chair or stand and turn around)?

[rocky nexus]

+1 for smooth turning being awful, the problem is forced rotation, not you directly rotating one way or another. guess its like another 10 vr levels above smooth walking lol

[vivid spade]

This works, but just feels wrong. Its like in some VR games how you can be riding a car and turn the car, but your camera doesn't turn with it and you can end up facing sideways if you turn hard.

Similarly if you're running against a wall and suddenly you hit a curve and are now no longer facing alongside the wall, it just feels janky.

I don't really have a solution for this so I might just really limit curved wall surfaces in my games playable area. Don't even know what other option there would be between the two but both just plain don't feel good in VR.

[sturdy coral]

Have you tried out the Jedi Knight II VR port? I remember that game had wall running, not a lot of direction changes but some control, and people seem to like the VR port, but I haven't tried it

[vivid spade]

Huh no I haven't, I'll look into that and see what they did

[glass yoke]

For working with the Quest 3, is there any information about the Texture Streaming Pool size?

starting in 5 to sort stuff out first is a decent plan

[oak ridge]

well, I updated it from 5.2 but it seems like these function nodes have been deprecated

just verified the engine and made an empty project and cant find the function

thats why you never update stuff, 4.27 for life!

perhaps there is something interesting in change log

ok, fixed it, there is a new optional plugin called XR Base where these functions have been moved to

Do I need sidequest to put the app on the headset? Or is there another way to get the files across from PC to the headset?

[rocky nexus]

that is certainly easy, you can also use meta quest developer hub app to do that. they both use adb to do that

when you make a release build there will be .bat file to install it on connected device

you must enable developer mode on the device, probably did so already

[autumn current]

Cool thanks, sorry I'm a bit clueless, my supervisor suggested the idea of using unreal as if it was easy but turns out they'd never even used it before😅

[autumn current]

I tried to package but got the exact same error I showed before🥲

[ashen dome]

Anyone using a quest pro for development? Thinking of picking one up over a quest 3 . and did you manage to get eye tracking working in Unreal ?

[quiet swan]

can someone help? I am getting 35 fps in a packed occulus quest 2 game in unreal engine 5.3.2. I was able to get 72 fps in the headset in UE4

I tried to install the meta VR plugin to see if it help but I get this error

LogOVRPlugin: Error: [XRCMD][failure] [XR_ERROR_LIMIT_REACHED]: xrCreateInstance(&createInfo, &instance), arvr\projects\integrations\OVRPlugin\Src\Util\CompositorOpenXR.cpp:2002 (arvr\projects\integrations\OVRPlugin\Src\Util\CompositorOpenXR.h:315)

[quiet swan]

also steamVR and meta seem to be fighting each other for control of my VR in UE5 crashing the editor

It just crashed my ox

[foggy brook]

MetaXR 5.3 plugin is totally broken. Regular OpenXR should work without the Meta plugin. Unfortunately if you do want to use the MetaXR plugin you really need to go to their fork of 5.3 for the moment

---

I can't believe it's taken me this long to try this, but has anyone found that if they try to launch an Unreal Engine 5.2 or 5.3 experience that has the MetaXR plugin enabled using SteamVR that they get either a totally black screen or an outright crash? Here's the log.

two things that caught my eye in the log:
[2023.11.29-03.54.01:094][ 0]LogOVRPlugin: Display: OpenXR runtime name: Oculus, version 2.1.4 LogOVRPlugin: Display: Support Non-Oculus runtime: NO

so not only does it think Oculus is the OpenXR runtime (it's not), it also explicitly says it won't support non-Oculus runtimes. What?

[silk lodge]

I've been seeing the same stuff. Makes dev with a bigscreen headset impossible with the metaxr plugin

[real needle]

Hello, all. I'm not getting VR Preview to work in 5.3 with a quest 2. It works just fine with a Rift S. I've tried just about everything, plz halp

[silk lodge]

did you try unplugging the rift, and were you in link mode on the quest 2?

[quiet swan]

@real needle unreal 5 crippled for vr

I get lower frames now because they removed mobile software occlusion

Unreal 4 preform better had less issues

Basically unreal 5 is like going back in time to the year 2015 back when unreal 4 was born with all the issues and bugs

The openXr plug-in doesn’t work with the meta plug-in and now all my VRE stuff don’t work in ue5 quest because meta breaks openXr

[silk lodge]

You can try the third party occlusion plugin

[real needle]

Oh yeah, tried a series of unplug and plug back in configurations. Running Meta Quest Dev hub too with link cable enabled and headset is confirmed detected. I disabled the MetaXR plugin and now it works but ONLY in passthrough mode wtf

I've been at this on and off for WEEKS

First it was trying to get the link cable to actually register

This is hell. I'm in hell.

does anyone knows how to set the log verbosity when running on quest2?
i know how to set it in the config for one log category but i need all.

[violet garnet]

Hello, question about the Oculus Quest 2 controllers not moving...

I am new to VR, and I have a question and wonder how to solve it…

In Unreal Engine 5.2, when creating a new VRTemplate and adding the Oculus VR plugin, packaging it into an APK, and uploading it to Oculus through the Meta Quest Developer Hub, it was found that the camera can move with head movement and the buttons A and B on the controllers are responsive. However, the controllers cannot follow the movement of the hands and remain on the floor directly below the camera, as if there is no offset. Has anyone encountered a similar issue and can offer assistance?

Thanks in advance.

[neon geyser]

Fast travel game ported software occlusion culling to ue5

[dreamy ivy]

you shouldnt be using the Meta XR plugin with big screen anyway, its a steam headset. Meta XR should be disabled for steam.

[dreamy ivy]

you say Meta Quest developer hub, you need the Oculus Desktop application for your headset to communicate with unreal.

[dreamy ivy]

are you using the OculusVR plugin or the MetaXR plugin as you need the MetaXR plugin.

[scenic warren]

Hi all,
Has anyone encountered the error "AutomationTool exiting with ExitCode=1 (Error_Unknown)" when assembling a build on UE5.3?
I can’t find a specific error in the log that is causing the crash.

[chilly pasture]

Anyone here knows how OpenXR, calculates FOV for VR headset

[silk lodge]

The bigscreen beyond is a way nicer headset to use for pie testing.

[dreamy ivy]

As long as your not doing quest specific content, I imagine it's really good. Unfortunately I'm not able to get one to try out just yet.

Although I'd love to get one eventually.

[silk lodge]

there's a lot of VR tests you can run without needing to be on specific hardware, and it's much more ergonomic. Besides the glare, it's a really fun headset.

[real needle]

Yeah I have Oculus desktop app running as well, and no dice. Also uninstall/reinstalled that.

I launch link cable and now its just 3 blinking loading dots, infinite load

[sturdy coral]

maybe this will work better https://www.meta.com/experiences/5841245619310585/

seem to support eye tracking, not sure about hand tracking

[rocky nexus]

will hopefully make more people play pcvr!

[sturdy coral]

hand tracking didn't seem to work at least in my unreal project, it does work with ALXR

it made you grab controllers to even launch it so I think it doesn't have it

[hard sparrow]

also what version of unreal are people using for VR stuff? is there a certain version that works the best?

[scenic warren]

Has anyone worked with Meta XR Platform?
After turning it on, it gives the following error in Quest 2. Does anyone know what this might be related to?

[quiet swan]

@hard sparrow I think UE 4.27.2 plus is the best version . Using us5 is like going back to the year 2014 with all the issues.

No software mobile occlusion in UE5

[limpid widget]

I am using ue 5.2.1 and it works fine

Official branch, not meta one

I can develop for all platforms

And I am facing no issues so far

[real needle]

I think my issue may stem from migrating my project from 5.2 to 5.3, because now my Rift S is having the same problem in this version as the Quest 2. I start VR preview and nothing happens in the headset but on my desktop it loads the pawn, you can see the hands covering the view.

Is there something I should be doing extra in 5.3 to get it to function? Something I have to change in the pawn???

Ok, disabling the MetaXR plugin returns a functional pawn. This didnt work for Quest 2 but it helped get Rift S working. What a shitshow

[dreamy ivy]

do the other way around disable OpenXR and keep metaXr plugin enabled if your targeting Oculus.

[real needle]

Oh, brilliant ok.. Hadn't thought of that, will test eventually. Cheers

and this is an expected message to pop up when doing so?

[dreamy ivy]

Yeah. Just press dismiss for now.

[real needle]

Ha, thanks so much. I'm like tip-toeing since UE has been putting up a fight with me recently. Trying not to anger the beast.

[terse vapor]

same here from mac os if it matters

[hard sparrow]

thanks I am thinking i may just go back to UE4 for this

im dealing with the screen fade not working issue because of mobileHDR or whatever

i prefer to be on UE5 but quest native games aren't going to use most of the features anyway

[dreamy ivy]

Put a plane infront of the camera with a dynamic material it's how I do it and it works greet.

[hard sparrow]

you may have read my mind lol, i was in the process of making a 3d widget component that just sits like 1 unit in front of the camera

i just saw that

i want to stick with UE5 for this since its for fun. not working at a studio where i have to stick to a version

i feel like i have seen GDXR somewhere

oh the VR template i saw online!! i tried out your product on my quest 3, it was really cool

how can we get logs for unreal quest 2 adb logcat -s UE4 or adb logcat -s UE5 doesnt work

[quiet swan]

anyone know the code to get the logs of quest 2 on unreal 5? adb logcat -s UE4 and adb logcat -s UE5 arent working

[wheat holly]

Would recommend downloading the 'meta quest developer hub' as it has some built in integrations for these things. It worked better for me then constantly messing around with commands.

It also does allow you to use commands though.

[granite eagle]

I'm using a Pico 4 in SteamVR. In my VR project I'm finding that texture shadows and details look pixelated / low detail. Any idea what might be causing it? Also do VR headsets themselves do anything hardware wise to alter the quality, I'm running Pico on ultra settings and I know this HMD can handle better quality (seen it in other games).

I'm thinking maybe it's launching in mobile quality or something. I have Forward shader enabled with high render project settings, not sure what else might be causing it.

[quiet swan]

@wheat holly thanks I downloaded it , its asking if I want to change my ADB paths

[quiet swan]

so there is more then 1 ADB I will try with this new one, to see if it gets the logs, I can see the logs when I put it on, but its spits it out to fast

hi there
How do you cast to the right hand on collision ?

i've been trying a ton of stuff

but i either get failed cast or weird collision ( its colliding before it's hitting)

thanks

[rocky nexus]

print yourself the other actor/comp, see what it hits

[real needle]

Quest 2 started working with MetaXR on and OpenXR off, thanks GDXR for sharing the doc notes I've missed. A few new issues I'm having: hands/touch controllers decoupling completely if I 'reset view' and I cant change sound output from going into the HMD. Say, I just want it coming out of literally any other source besides the headset, the sound out is only going through the headset, even though I set the output to be different (RealTek card, monitor speakers, etc)

As a side Q: any idea how I can prevent objects that I grab from going through collisions? If i drop the object it responds to the collision with normal physics, but say I'm holding a screwdriver I can just pass it through a surface, let go, and usually just glitches out because physics kick in while inside of the other object.

[hard sparrow]

i feel like this should be showing a newer SDK for me

or is that the NDK version?

i have 34 and 33.0.1 installed for the SDK but 25.1.8937393 for the NDK

[cerulean lichen]

I've been using Physics Constraints to do this. Added a constraint component to your hand, and when you pick up an object, rather than attaching the object to the hand mesh directly, use SetConstrainedComponents with component 1 being your hand, and component 2 being the object you want to pick up. Then when you want to drop the object, use Break Constraint. This should stop objects you pick up from passing through geometry

Looking at the VR template, I’m confused how the camera knows to move itself. It appears that it’s attached to a blueprint with a Pawn parent and I don’t see blueprint updating the camera position every frame.

[grand otter]

Has anyone worked with VR yet, i got full body moving beautifully, but my arms just are not right. i cant put them down by my side, and when raising my hands they straighting out far to quick, its almost like there not leveled where they should be.

the only thing that is SORT of a fix is changing VR root to -60 but it doesnt seem like the right way to go about this and its kinda janky lol. also when i stand up from a crouch the hands and arms raise higher, and cant go as low again, then when crouching they go backwards and i need to reset position with controller

This is my basic set up

I have another set up with fabrik nodes instead does same thing only joints pop out more with it

[rapid saffron]

Hi everyone. I ask you for help. I don't understand which version of Unreal Engine I need to install to develop apps for Meta Quest 3. Should I compile the fork edited by Meta, which is older than 5.3.2? Or do I simply install 5.3.2 following the directions on the official Unreal website?

[sonic fjord]

you need a sufficiently old version of android build tools, and this is not documented. I think 427 works with both 30.0.1ish and 33.0.1ish, while 425 requires 30, so logically, I'd try 30 for 426.

ndk 21something? that part should be documented.

[sonic fjord]

any camera on a pawn has bool "attach to HMD" (or something like that) set to true by default, so it will use that camera if VR is enabled. if I recall correctly, the parent component of the camera gets set to the playspace floor center, while the camera automatically moves relative to that behind the scenes in engine C++.

VR Expansion plugin has the logic needed to work around that with it's own character class and movement component, but I've also managed to build my own based on the native character class in the engine, lol.

I know PSVR2 has this but I don't think it works for PCVR or standalone like that

Ah cool, thanks. I’m aware of Haptic Studio but had been hoping to achieve the same effect without using the Meta XR plugin. Appreciate the info!

Hi guys. I try to implement relatrively simple VR hands with preventing colliding into enviroment. Im using this setup: https://www.youtube.com/watch?v=bBykiDW1wbw
I add physic asset to hand models, but the problem is that if physic type for phys asset is set to Default or Simulated, hands doesnt collide into static meshes, but they no longer response to animation blueprint.
If phys asset type set to Kinematic, then animations are work properly, but now hand will only properly collide with physical actors, but will ignore static meshes.
How to solve that?

[tired hamlet]

Hi everybody, I am a long-time user of UE4 and I am migrating to UE5. My typical usage is deploying Android Virtual Reality stuff to Oculus headsets (which are Android machines), and I work under MacOS, so I have Android Studio installed, etc etc. Everything Works Fine So Far.
Now, I would obviously like to keep a 4.27 working version when migrating to 5.3.2, but I must update Android Studio etc as stated in https://docs.unrealengine.com/5.3/en-US/how-to-set-up-android-sdk-and-ndk-for-your-unreal-engine-development-environment/ . So, I should be able to do what is stated a bit later in the page, "Manually Target SDK Paths", but for the life of me it does not work. If I change any path in Edit > Project Settings > Platforms > Android > Android SDK section, in ANY version of my installed UE (4.26, 4.27, 5.3.2 ....) it will change EVERYWHERE, in ALL UE installations, as if those settings were saved in a "super" BaseEngine.ini configuration file, which I cannot find (I am running grep all around for hours now). Changing the settings by editing a specific BaseEngine.ini file as explained in the page seems to have no effect. So, I am actually unable to set different Android SDK paths for different UE4/UE5 installations. Do anybody here has done something similar? Please note, again, I work with MacOS, not Windows. Please note also that i CAN find trace of my manually configured paths in files like CookedIniVersion.txt and in the Saved/StagedBuilds/..../BaseEngine.ini , but I cannot understand where the SOURCE of those modifications is located, and why is shared between all engine versions...

[sturdy coral]

[junior halo]

You can have collision without enabling physics. Either don't simulate physics in your hands to make the animation work, or if you want to set individual constraints for each bone, add Physical Animation Component to your hand actors.

[summer linden]

The main goal is to have each object in the world (both physic and static meshes) reacting properly to phys. asset capsules, but with keeping animation from animation blueprint working. If simulation are disabled, hands will not collide with static meshes. Is it possible with phys. animation component, no?

[junior halo]

Hands should collide with static meshes with physics disabled, enabling physics is to have the physics asset take care of the contraints, but I guess you already have a contraint that joins your hand mesh with the motionController location, right?

It should collide but if the mesh is static it should push your hand back instead of moving the mesh

[summer linden]

With disabled physics and physic asset? In my case disabling physic simulation will make static meshes "transparent" to hands 🤷‍♂️
My current setup look like this: so 2 meshes with constraint. left_meshMC is hands model with physic asset.

[gloomy cairn]

Ok in that case try adding physical animation and play around a bit until you find a good mix between physics and animation. Check this tut: https://docs.unrealengine.com/4.27/en-US/InteractiveExperiences/Physics/PhysicsAssetEditor/HowTo/ApplyPhysicalAnimationProfile/

And it doesn't work on quest 2... Well it does, on the left eye. On the right eye seems like it's broken (the overlay is always rendered so it seems custom depth or scene depth simply return wrong values)... Does anyone have any ideas? Is this because of mobile multi-view?

would anyone know why my niagara particles do not show on a quest 2 device. but show on the editor? using unreal 5.2 branch from meta?

Hey guys. Whats the best way to fade a VR camera to black and fade out again?
I wanna do it between swapping out dynamically loaded levels, however the normal way of using "Start Camera Fade" from the Player Camera Manager doesn't seem to work.

I tried attaching a widget to the player screen and fading a black border on and off, however the widget is desynced between the two different eyes inside the headset, leaving a weird effect.

Is there a better way?

(I'm running on a Quest 2 using Airlink from a desktop)

nwm... I'm an idiot

I didnt delay the fade in/out between them, so they would instantly cancel eachother out

[hot rampart]

I think it should be CPU Sim to work on Quest

[mighty carbon]

GPU particles are disabled for Quest, but you can re-enable them via Device Profiles.

Any template to attach left and right controller with real time extinguisher in ue4

[mighty carbon]

GPU particles work on Quest, but I guess there some cases where they can cause instability and crashes. I personally haven't experienced those kind of issues.

[royal thorn]

particles works in quest but dont know why some cause issues.

[sage gulch]

if you burst too many at the same time it overloads it

thanks a lot ali and @mighty carbon

Any leads here

[chilly pasture]

Anyone know why GPU Sim Particles not working in Quest2 Android Vulkan ?

[chilly pasture]

thanks

[foggy oxide]

my intuition is that maybe the gpu is too overwhelmed by other processes +overhead. considernig is stereo rendering and mobile.
in my previous project every time we spawned particles there was a big hitch. we needed to use some pcg that never worked well.
so meta prolly decided is best to disable.

[rocky nexus]

there is a hitch for cpu particles as well, perhaps it is even bigger for gpu ones

[chilly pasture]

yes makes sense, i never saw hitches, my particles system is pretty simple. but i see we have other GPU stuff and our CPU is pretty free so decided to switch to CPU particles.

[foggy oxide]

awesome! it's only my idea though. take it with a pinch of salt.
but in the projects i worked the gpu is always overwhelmed and cpu not so much.

[tired hamlet]

OK. Anybody here which managed to get the 5.3.2 OpenXR Template ON MACOS (M2 MacBook Pro) compiling, deploying and correctly running natively (I mean as an Android app) on Quest 2? I installed the suggested Android Studio stuff , SDK etc, I can compile it and deploy it, it starts on my Oculus but as soon as I wear it it crashes with this stack trace:

I am now playing with some rendering parameters etc but with no luck

BTW, is there anybody AT ALL developing Quest native stuff on MacOS? 🙂 I am used to, I have quite a knowledge about what works and what does not in 4.27, but there is a time one must move on, and I am trying to get something running on 5.3.2...

also because CPP compilation is now broken for 4.27 and I will need to develop some C++ stuff soon, so I must find a solution

(at least, is broken on my machine. I should probably try to install an older XCode, but Apple is always a pain when you try to downgrade stuff)

Hello, Does anyone here know how to make it possible to interact with a widget, not with a "laserpointer" but with the actual finger of the Hands meshes, like the index finger?

it feels like such a...natural and obvious way to interact in VR, yet I can only find things about doing it with a laserpointer from the controller.

[bold ledge]

Hey,

how can I use my Quest to as a PC VR Headset?

Connected it with Link but I can't play the VR Template. I can see it but it never takes over any control from the quest 2 ?!

[civic wharf]

have u set the OpenXR Runtime in the occulus app as active?

[rocky nexus]

Make the laser pointer really short and attach it to finger. Press on overlap with widget plane and collider on a finger

[civic wharf]

could I use the widgetineraction component for that? I tried searching the widget interaction component to look what it does exactly, but I cant find it in the content drawer

[rocky nexus]

Thats how you press the widget, its a component you add to your actor

[sage gulch]

make sure the preview window is fronted to the OS

[civic wharf]

figured it out, thank you

[civic wharf]

Hello, I have a problem with widget focus (I guess). I have set up a WidgetComponent, and a WidgetInteractionComponent. If I click once on the Button in the Widgetcomponent, everything is fine. The button then switches a Widget in the MainWidget via a widgetSwitcher to an InventoryWidget. If I now click on one of the Inventoryslots (where the items are displayed), the InventoryWidget(that contains the slotWidgets) isnt reached, and therefore the slotWidgets arent aswell. If I now click on another InventorySlot, it does reach the InventoryWidget, but clicks on the SlotWidget I previously tried to reach. So it doesnt take the first hit on the InventoryWidget, but for every other click after, it uses the click location from the previous click, alsthough the new correct click location is calculated correctly and passed as a customHitResult, before it actually executes the click and release sim

This is the click and release input on the WidgetComponent which runs everytime I click on the WidgetComponent.

This is the WidgetComponents WidgetClass, with the switcher, that switches to "ButtonInhalte" if clicked on the Inv Button .

[sturdy coral]

might be a different bug, but try the console command "Slate.EnableFastWidgetPath 0 and see if it works

[sage gulch]

do you guys use Precomputed Visibility on mobile?

[civic wharf]

sorry for the late reply, was off my pc. Tried that now but it doesnt work...

I also now plugged in a second trace right after the setCustomHitnode and it literally now

Does a trace, passes the result as custom hit to the interaction component, does a trace again with the last hitresult of the interaction component. while the first trace is always correct and doing excatly what its supposed to be, the 2nd trace already gets false data. the hitresult is set one node before the 2nd trace, yet by getting the last hit result Im getting wrong values

on first click, the first trace reports the right hitresult, the 2nd trace returns 0, on 2nd click, first trace returns correct hit result, 2nd trace returns the correct hitresult from the first click and so on.

[sturdy coral]

Instead of passing the same trace points from the result, try lengthening it incase there are rounding problems

Start into start, ((end-start) *1.01+start) into end

[civic wharf]

But a rounding problem wouldnt cause the first hit result to become 0 wouldnt it? Alsothe 2nd trace returns the correct hit but from the click before the current click. Obv then on the first click there is no "previous" click so it returns 0.

https://imgur.com/a/WYRFCMQ

for a weird reason tho, the first click on the Inv button registers correctly despite supposedly having no hit result set

[sturdy coral]

I'll have to look closer at what you are trying to do later, I know they do some weird stuff with replacing the hit result in the widget interaction component, and if you are doing cylinder geometry it gave you a point as if you had hit a plane joining the left/right sides of the cylinder section

[civic wharf]

im not using the cylindric shape

@sturdy coral If I cache the hitresult and use the cache for the 2nd trace the trace it correct, just like the first trace but the set custom hit still uses the previous hitresult, despite having the cached hitresult pluged in.

setresult is updating and not updating at the same time...

[civic wharf]

@sturdy coral I figured it out. After looking through the c++ implementation of the WidgetInteractionComponent and its functions, I still had no idea what exactly the issues was, because I have no idea of c++ xD, BUT, what I could figure out was that SetCustomHitResult literally only does customHitResult = HitResult, so it was unlikely that that was the issue. Looking into the PressPointerKey however, revealed to me that suspicious things are going on when it checks for a last Widget Trace, which, if no LastWidget exists, calculates one by performing a trace. If one exists it does a whole lot of things on it for some reason I think are unnecessary, but Im not a programmer sooo. I think what it does there tho, is messing with my previously setCustomHitResult.

So what I did now to solve it, was not using a customHitResult at all and turning the interaction source back to World instead of custom. This way, whenever press or releasePointerKey is called, it cant find a LastWidget and does its own trace, which works.

So essentially, at least rn, Unreal doesnt seem to want me to define my own custom hit to detect a "virtual touch", but wants to do it itself. I still think this isnt how it should be, since the press and release pointer key nodes should just simply use the custom set hitbreak and straight up calculate it into widget coordinates to simulate a click. Anyway. It works now (just took me all night to figure out.....). Just wanted to thank you for your help and tell you what I found. who knows, may it becomes usefull for you some day.

🙂

[sturdy coral]

Nice, there is some obscure code in there, I ran into a lot of issues getting it to work with custom mesh shapes

Tried to get touch based pointer events working for multitouch and better dragging of lists and stuff (touch vs tap) and had a lot of issues too but that might be fixed by now.

It got into some kind of touch gesture detection code that didn't work right with virtual slate windows.

[civic wharf]

How do I have a 3d Widget rotating based on the headset Rotation but without the up down rotation? Like the quests pop up window that turns up saying we need to set a roomscale or stationary when the headset is powered up but put of the bounds from last session?

[mighty carbon]

LookAt node?

[civic wharf]

probably, D you have any idea how ?

[civic wharf]

ok so I figured it out without look at since that gave me wrong values. Technically its working now as I want, but whenever my headsets world rotation becomes smaller than -180 or bigger than 180, the Yaw Value switches to 180, or 180 to -180, which messes us my calculation for rotating...does someone know a way to fix that?

[mighty carbon]

Do you folks have YouTube on your planet ? 😂

Could have watched a video or two about LookAt

I use it all the time

[sturdy coral]

You can check if it is negative and if so add 360 degrees to the value but you are probably still going to have problems

What you need to do is get the head direction by not just the forward vector, but lerp to the top of head vector as the user looks down. Then project that to the ground and normalize. Then have the UI face the opposite direction of that vector with lookat or similar method, or more complicated if you want it to move up and down and pitch too but never roll

the stuff with lerping the forward vector depending on how down you are looking is so that the forward direction doesn't accidentally reverse when they look down too far

[civic wharf]

figured it out aswell...

@nova rock you might want to ask at VD discord about that issue

Someone here who could help me with the physics constraint component?

I could constrain a static mesh successfully, but cant do it with the skeletal meshes of the template hands.

[sturdy coral]

ALVR/ALXR works best I think, virtual desktop is best image quality but too slow to reconnect when the headset has gone idle

at least on Pico

[civic wharf]

please someone who can help me out with physic constraints. Im going insane...

[novel gorge]

Code it by yourself with interpolation of rotation and location of the motion controller.

[civic wharf]

got it already to work. I had a test static mesh where the motion controllers are which caused the issue because I made it hidden in game and it was so small it got covered by the other meshes in the pawn bp. It had collision and physics on aswell, so it messed with the other things

[digital cave]

You can save a lot of time by using the free VRExpansion plug-in for this

[civic wharf]

yeah, ive heard a lot about it. I've never used Plugins tho, because I feel like, if I get problems with a plugin, its much harder to get actual help for it, since it requires other people to not only use it but be good enough with it to help.

and usually the amount of people being good enough to help out, especially with niche questions is much larger for base UE than a plugin. VR aswell, since the VR com is still relatively small compared to traditional flatscreen.

[turbid plank]

new to working on vr in unreal (was using unity for a couple of years till september drama), it seems to me that unreal definitely require more peer to peer help, rather than just pure google and chatgpt (chatgpt not great for unreal)

[civic wharf]

yo, can someone help me with hit events not firing?. Im trxing to hit a tree with an axe, both have physics on and generate hit events ticked, they block eachother as expected but neither of them generates hit evens from eachother.

ok the tree does generate hit events from the axe, but only if im not holding it (via the custom setting of the grab component)

[whole nimbus]

Use print string to isolate the problem

Bugs fixed

[civic wharf]

wdym? Im using print strings to check if a hit event is firing, Its just not firing when hitting it with the grabbed axe

it does fire when the tree collisdes with the axe while Im not holding it. But looking into the grab component to see if it changes anything while grabbing, theres nothing too. The axe gets attached to my pawns hand skeletal mesh, physics remain on. I thought maybe the hands kinda ovveride the axe when attaching it to them, so I enabled everything on them aswell, but still no hit.

hmm, It triggers the hit if I attach the axe to the motion controller instead of the hands skm. Is this intended? Can skelatal meshes not trigger hit events?

[wary bridge]

Hello !
To export my ue5 game to my Meta Quest2, which run on some kind of android, can I just package to android following a random tutorial, or is there specific settings needed for Quest2 ?

[tired tree]

@civic wharf UE5 has multiple issues with skeletal mesh attachment currently where it is merging the body instances to the parent and SKM bodies are very buggy in engine

the skm will likely need hit events thrown for that axe to throw them when attached to it

but you'll run into other issues I assume

with events throwing on the parent and not the child and other such oddities

[civic wharf]

@tired tree good to know, I already assumed there are issues tha go beyond me just not understanding why it doesnt work. What would then be the way to go for such a mechanic? Theoretically, it does work, if I use the default attachment macro of the grab component from the template which makes the parent of the grabcomponent the motion controller component. But because I wanted to have weighted hands that become slower the heavier the object one is holding is, I used a physics constraint to constraint the default VR Hands to an empty static mesh parented to the motion controllers. So to have the Object Im holding follow the weighted hands properly I thought attaching the Object directly to the skeletal mesh hands would be the easiest, to keep the physics being simulated for f.e cutting a tree, or mining an ore, because I need the Impact force the Event hit gives me. But event hit only works with physics enabled, which seem to not work with the skm hands...

[tired tree]

@civic wharf its because without physics enabled you have to sweep the movement which doesn't happen with attachment

and like I said, pretty sure the parent (hands) would need the simulation generates hit events turned on for it to work with UE5 currently

[civic wharf]

I tried that, but it didnt work either

[tired tree]

UE5 does some really funky things currently that UE4 didn't, lots of bugs and not sure how many of them are intentional or not

it doesn't route a lot of things to the correct body instance

in my example setup i take the reverse route and attach the hands to a simulated object that is constrained

that setup doesn't have this issue

but i do have to remove the hand collision for now when attached due to the SKM bugs ruining the collision

[civic wharf]

huh...thats smart...didnt think of that

[tired tree]

have 4 or 5 bug reports and reproductions submitted but they haven't been touched yet

[civic wharf]

Theres a few things I find a little too...complicated for the standard they should be in VR.

Hello, does anyone know of a good tutorial on how to access virtual reality with OpenXR directly through C++? My idea is to make a C++ plugin, without using the OpenXR Template.
It's amazing how difficult it is to find something on this specific topic.
Thanks in advance.

[rocky nexus]

there rarely are tutorials for stuff like that, you dig into existing examples and source and figure it out

[uneven vortex]

Yes I know. Yes, I have almost all the frameworks there are, VRTemplate, VRExpansion Plugin, VRGK, VRPhysicsBrawl, but none of them convince me for one reason or another. Too bad VRGK didn't end up using cpp; On top of that, the author has abandoned the project not only for cpp but for the current one that was already good in Blueprint.
I was just looking to see if there was something on the most official channel, but it shows that VR is not a priority.

[novel gorge]

I guess then you have to use it like any other third party C++ library... Download, include, build, link libraries etc. But usually it's better to use the wrappers Unreal offers, because they are made by experts from Unreal.

https://www.khronos.org/openxr/

[uneven vortex]

Maybe I didn't explain myself well: I was asking if anyone knew of a good tutorial or course with a practical, step-by-step implementation on how to implement a basic VR with OpenXR from cpp, since I intend to make my own cpp plugin to take care of it with maximum performance; I imagine Unreal Source is the best place to find out if such a thing exists. Obviously, I know the OpenXR home page by now.

[novel gorge]

Ah, I understand now. When I started my VR project, I also searched for something like this and did not find an C++ example for the current engine's version. I had to translate the BP example project. At first it's a bit complicated, but it's not really much.

[uneven vortex]

As a first step, the first thing was to see if there was already something done, so as not to reinvent the wheel, I am surprised that it is not.
Well, as I said, I have many frameworks where I can find out, I think I have almost all the ones available from the marketplace and the free ones, with their code in blueprint or cpp.

[amber needle]

the time between visual feedback touching a button in my VR template, and a beep sound I play for testing, has some gnarly micro delay, that makes the who idea a non-starter because I can't do rudiments with that delay 😦

Hello Guys,
Does anyone have any tutorials on how we can optimise the graphics in UE 5 for quest 3 ? Like Asgard wrath 2.

[digital cave]

some topics to look into are static lighting and trim sheets

[sterile sandal]

Thank you 😊

[digital cave]

If you are new to graphics you might want to start without doing optimization first. perhaps build a scene to the level of fidelity that you want, then work on converting it to perform on quest 3. there are a lot of hard lessons to learn, like how you basically can't use decals on quest

[sterile sandal]

Ok. I'll check

[rose spoke]

there is a specific branch of unreal that have a lot of VR extras, this includes changes to engine source, likely you'll find good stuff there
https://github.com/Oculus-VR/UnrealEngine

and here's the docs related to it
https://developer.oculus.com/documentation/unreal/unreal-compatibility-matrix/

[novel gorge]

Lesson 1: translucency is evil.

Really... For VR try to avoid it as much as possible.

[rare tulip]

Disclaimer: I'm speaking from experience working with Quest 2, I have not done dev work for Quest 3. Some of these pointers are also just good practice for mobile.
+1 on Translucency is evil. stylistically do everything you can to avoid it.
Draw calls are a concern always, you will find them more of a concern than when making non-vr games.
On that note, by default Dynamic mesh batching is not enabled on mobile. You'll need to enable it in your ini files if you want to use auto-batching to save draw calls. But this does have overhead, and will not be wise for every project.
Culling: Dynamic occlusion culling will not be performant, as the option for CPU occlusion culling on mobile is removed in UE5 and you don't want to do GPU culling on mobile VR.
On that note, your GPU is precious. Particle systems with GPU emitters are to be avoided. When building materials, favor doing logic in the vert shader over the pixel shader as much as you can, such as when manipulating texture UVs. Your texture samplers within materials are also precious.
Baked lighting is your friend. You will have to do a lot of extra optimization work if your style requires even a single dynamic light, for the sake of your sanity just don't. You can fake self-shadows within materials and use blob shadows controlled by Material parameter collection if you need to kind of fake dynamic lighting. Material based lighting solutions are absolutely your friends here.
Enable Dynamic resolution scaling if you're able to. Meta's current requirement is that you don't dip below 85% screen resolution for extended periods of time, which means you can down-res quite a bit if you are heavily pixel bound to get frames back.
A lot of this is just "best mobile development practices" in general, so lean heavily into related documentation to that.
This video from Tom Looman has a lot of extremely good information on optimizations you can do, especially when he starts to talk about the signifigance manager and skeletal mesh optimization: https://www.youtube.com/watch?v=G51QWcitCII
Again, I don't know how much extra headroom the Quest 3 gives you over the Quest 2, I've been focused on Quest 2 projects thusfar.

[sterile sandal]

Thank you for the suggestions 🙂

I know it and I will end up using it when the project is almost finished, so I can use hand tracking and any other Meta changes, but it always updates much later and it is better to use MetaXR or even OpenXR in the meantime, since with MetaXR I already had some problems with versions with bugs. That's why I'm more interested in directly using OpenXR now.
Besides, it's not like it's going to be an exclusive Meta project.

Tom Looman is my favorite teacher. In theory, his new specialized course on optimization for Unreal Engine should appear in a short time.
In any case, he already has an excellent guide on his website.

[uneven vortex]

I had been told that VRGK “Lite” worked completely and the full version had some small drawbacks, but it seems more like a workaround for VRGK lite to work, eliminating the things that cause problems, instead of fixing them. Sorry for the created expectations.

In any case, here is the Community project of VRGK (lite): https://github.com/VRGK-Community/VRGK-Community-Project

Hi!

Can I develop a VR game using C++?

I'm asking this because I've found a blueprint template, but there isn't a C++ template.

Thanks.

[novel gorge]

Yes, there is no official VR C++ template. But of course can you make a C++ VR project.

[lusty whale]

Thanks. So, I have to use the Blueprint Template, and then add a C++ class, isn't it?

[novel gorge]

I forgot how to make a C++ project out of a blueprint project (I started my project about 10 month ago), sorry. But there are sure tutorials somewhere how to do that.

[little marsh]

Hey can you get finger splay from Meta's handtracking example? Or are they punks and keep all of it hidden?

[uneven vortex]

Exactly, you can create a project from the Template and add a C++ class or you can create an empty C++ project and then add the Template, as you prefer.

[proven bronze]

Hello guys, im looking at the market place for environnement assets which filter do i need to use for quest 2 and 3 support?

Does Anyone Know How To Make A Ragdoll Character In VR that i can lift up and interact with like in bonelab?

[crisp wasp]

vr expansion has exactly what you want you can find something there

also hi, i wanted to ask if anyone is having these issues with unreal engine after packaged to quest:
some objects and widgets are interestingly shifted on one eye but normal on other
also sometimes the objects are disoriented completely.

also it can be reproduced with a simple height fog, it also shifts silightly right on the right eye.
does anyone have a solution and thank you in advance

[unreal oar]

Thank you

[rocky nexus]

stuff like that often means it is simply not supported on quest

[crisp wasp]

so it is not a setting problem or so? it is fine then thx

[rocky nexus]

obviously widgets are supported and should work, in that case some setting they you are using is the cause

many things do not work, and it is a pita to deal with

i dont recally hands shifting around in that template, might be some general graphical setting you are using

[crisp wasp]

kinda frustrating if not solved

[rocky nexus]

afaik the problem is mobile multi view, it might be required for quest, but not all shaders support that resulting in stuff being in wrong place (or something like that, tricky stuff). or maybe it was instanced stereo? at any rate, having to render stuff twice is the problem. that also means it should be possible to fix, even if difficult

[violet spear]

My meta quest 2 left eye was turning to black and Changed some settings and it fixed it!
You can test it as well.

Enabled openGL, Mobile Multi-View, MSAA, and disabled vertex fogging…, which solved the left eye black problem, and also improved the anti aliasing issue I had with the FXAA

Hi there! I have been trying to generate PSOs for my project and I have been able to "generate" them but, I just keep getting a failure message that the PSOs were unable to be saved on Meta Quest 2/3 for UE 5.3

android.permission.READ_EXTERNAL_STORAGE
android.permission.WRITE_EXTERNAL_STORAGE

I also saw that some people found luck in adding the checkbox in the Project Settings:

Use ExternaFilesDir for UnrealGame Files?

I also had no luck with this either. Is there any other way to get this to work? I'm still under the assumption this is some kind of permissions issue as when I navigate to the Saved/Logs folder it is empty. Any help would be appreciated.

[meager thorn]

Anybody have ideas why the VR template behaves like this in my Reverb? On the monitor the view is smooth, but in the headset it's all choppy

[rocky nexus]

that a preview? have the same on quest link/vrd pretty mich. fine in build...

[meager thorn]

Yeah thats preview. Hm I'll try a build then

So the jitter stops when I change it to low scalability. Even medium is pretty bad.

[novel gorge]

Try another - don't know how you call it - I mean the software like Oculus, SteamVR, WMR etc. For me I get the choppyness with with SteamVR. I have to use the Oculus software.

[meager thorn]

Yeah I think I know what you mean. I've only got OpenXR plugin enabled right now

[oak sandal]

I am currently testing a scene in desktop VR on the quest 3 using some raytraced shadows. They are not being denoised in the right eye! I'm using 5.3.2, deferred rendering. I have tried enabling and disabling Instanced Stereo but it has no effect. Any ideas?

[cursive wigeon]

Hi all,

Since SceneDepth/CustomDepth seem to be broken in mobile VR (with Mobile Multi-View) on the right eye, I thought I'd try to circumvent this somehow by using the (correct) values supplied for the left eye and just reusing those for the right eye.

Would it be possible to write SceneDepth/CustomDepth to a custom parameter somehow in the left eye pass using ScreenPosition or StereoPassIndex and then just read those values for the right eye? I'm aware this wouldn't be perfect due to the minor perspective difference but it's better than nothing (SceneDepth/CustomDepth always return the maximum value for the right eye as of UE 5.3.2 at least).

Thanks!

[sage gulch]

any fix for 5.1 sending audio to the desktop output instead of the hmd? it persists in packaging and I can't seem to get it right via settings

[hallow knoll]

That's a system setting and not UE

[sage gulch]

[rare tulip]

Anyone using UE5.3.2 and currently trying to ship to App Lab? I'm having a little trouble meeting cert due to failed recenter behavior and could use an extra opinion, perhaps there's something simple I'm missing.
Testing The VRNotificationsComponent Recentering in UE5.3.2 on a for-distribution shipping build on Quest 2. Both the HMDRecenter and VRControllerRecenter Dispatchers are connected to a Reposition function. The VRNotificationsComponent has been added to the VRPawn in this project created off the VR Template.
OpenXR enabled, MetaXR disabled: Neither recenter events fire
OpenXR + MetaXR v. 60 enabled, Both the OculusOVR+OpenXRBackend and Epic Native OpenXR + Oculus Vendor Extensions XR API: Neither recenter events fire
MetaXR enabled, OpenXR disabled: recentering does function successfully! But the image is washed out and only rendering to the left eye. Disabling Mobile Multiview causes the image to only render to the right eye.

[sage gulch]

what an annoying bug to get hung up on

[limpid widget]

I think VRNotificationsComponent needs to be on the PlayerController for the OpenXR enabled part, but I could also be wrong, haven't checked this part for quite some time now (and I'm also only on 5.2).

[rare tulip]

Doesn't seem to be the case for 5.3 at least in my testing, I tried shipping builds with the component on the player controller, made builds with both of the Meta XR API's and still could not get the recenter event to fire.

Tried a build with the MetaXR plugin removed entirely, OpenXR only, with the component on the player controller, and also couldn't get the Recentered events to fire.

[hallow knoll]

I've reproduced it, not sure when that broke I feel like I was testing the notifications component not long ago. We're most likely not doing another hotfix for 5.3 but I will provide the CL on Main when it's committed. As a note, you don't have to do the "reposition" logic yourself once the event is called - recentering should "just work". The recentered delegate is there if you want to do something specific in your project when the user calls recenter.

[rare tulip]

Thanks for looking into it! Very much appreciated.
And good point on the reposition logic, I'll give a try at adjusting my main level to utilize the default logic instead of my own.

[neon geyser]

how can I generate the debug symbols for a Quest APK?

I checked "Include debug files" in project settings but I'm only getting an APK when build completes

Hi do anyone how can I resolve this issue?
this is screenshot of how level looks when I run packaged build on VR headset (oculus quest)
NOTE: I have changed some of the values in defaultengine.ini but I don't know which settings caused this issue.

[limpid widget]

So Recentering still works, it's just the event that is not called?

[rocky nexus]

thats Quest1? afaik stuff looks fine on Q2/3. dont remember what setting exaclty did that, maybe vulkan

[desert laurel]

yes thats quest 1

[desert laurel]

vulkan is enabled

[rocky nexus]

q1 is no longer supported, running stuff standalone on it wont be a nice experience sadly

[desert laurel]

but Its what I have right now to test things.

[rocky nexus]

use link

that looks like ue5 screenshot, dunno if you even can use opengl there, might need to downgrade to 4.27 if you really must support Q1. been long time since ive used one

[desert laurel]

I did some settings changed in default.ini because earlier when I packaged it and run on VR headset it shows that 3 dot loading screen for 4-6sec and then it crashes.

[rocky nexus]

settings you did are fine, q1 is simply no longer supported, nothign to do about that

[desert laurel]

yes it is ue5.3

[desert laurel]

I have disabled the opengl in my project settings

[rocky nexus]

try to use it instead of vulkan

maybe that will help, i dont remember what was the cause but it did see the weird colors long time ago when ive still tested on q1

[desert laurel]

alright thanks will try do and see if it helps

[zealous cradle]

Anyone have this issue

i get this the moment i start the VR template

[hallow knoll]

It's specifically the "user recentered"-callback from the Oculus Mobile runtime when you're notusing the MetaXR plugin, and your Tracking Origin is configured to Stage. It works w. the MetaXR plugin, and without on PC, or if you're in Local (Tracking Origin = Eye). The Reset Orientation and Position function works when called, but we're not receiving the delegate that the user has requested to recenter. We're looking into it!

Hello. For a third Person VR approach, wo0uld it be better to create a ThirdPerson Project and alter it for VR, or create a VR Template and alter it for ThirdPerson??

[onyx urchin]

Is anyone using UE5.3.2 with Meta XR plugin v60? Online docs mentioned that the MetaXR plugin don't play well with OpenXR in 5.3. I cannot get VRPreview or the hand tracking to work with OpenXR enabled. Can anyone advise their workaround? How do you iterate quickly in VR without the preview? Also, how do I enable my hand tracking? Thanks!

[rare tulip]

Yup I'm using it daily right now. You disable the OpenXR plugin and MetaXR will still function. It will default to the OculusVR + OpenXR backend XR API option in the Meta XR settings, you'll lose access to some of the new motion controller positions, and some nodes will no longer return successfully, such as the GetMotionControllerLinearVelocity / AngularVelocity etc. Also IIRC there's some settings weirdness with mobile multi view when testing in engine, check the online docs for details.

[whole nimbus]

would really appreciate if anyone can suggest where I should go from here trying to make a fbik player character:
I used control rig to build most of the IK, the arms and legs, but I left the arm twist section because I don't really understand it.
So now I don't really know how to connect the hands. If I should use cast nodes like they do in the tutorial to animation sequences that are blended between each other, and whether I should do this on the full mannequin or create a separate rigged hand asset and socket it to the fbik body. Hope that makes sense

Basically got the fbik working with manny without hands, and don't know the best route forward

Obviously my twist joints are terrible, but I don't really understand what I'm doing in control rig beyond tying some ik nodes together.

Hello I'm using a phys constraint for a lever. So only the movement to pull the lever up and down are allowed. In 4.27.2 the same code works perfectly fine. If I pull the lever in 5.3.2 i can also move the lever in all locked directions. If I let the lever go, it will snap back in the right position, but this breaks everything.

If i lock everything in this example, it can also move the lever in all direction. If I let the lever go it will snaps back to its locked position like a spring.

How can I fix this weird behavior?

Alright who wants to team up and try to make a character controller similar to assassins creed nexus? Looks like the days of the boneworks hexabody ik rig are over, AC Nexus feels like a basic character controller with animations. If anyones interested in trying to get this to work over the next few weeks, or to collaborate with me on it, feel free to reach out

[whole nimbus]

looks to me like the chest and legs would be a part of just standard anim bps blended with procedural animations on a control rig, which help for planting feet against a wall when climbing. The arms are made of two parts, the lower arm which has the standard degrees of freedom, and the upper arm which secretly isn't quite attached to the forearms. This is very noticeable when you rotate your forearms, notice the upper arm doesnt move at all, and does an incredible job of following the target effector, in control rig terms, meaning you don't get any twisting or weird elbow behavior typical of a generic fbik vr setup. You can see through the character model in the opening cutscene and see how they carved the arms out of the chest, and basically socketed the VR arms into the animation body.

the upper arms dont even move forward or backward, its like they only have one degree of freedom

here's what I'm going with

of course control rig to govern the feet on the anim bp

Hi!

I'm reading this https://docs.unrealengine.com/5.3/en-US/vr-template-in-unreal-engine/ and it says: Before you can use the VR Template, your device will need to be set up for development in Unreal Engine. See the documentation in XR Development for your device to ensure it's set up correctly.

But I can't find it. How can I set up the first HTC VIVE model for development?

Has anyone figured out how to do alpha masking in standalone VR? Basically I'm trying to create a portal in the walls in passthrough, so I want to block rendering of objects that aren't visible through the portal door. I've tried a number of tricks, such as having an invisible wall render to depth only, or using custom depth and a post process material. These work great in the XR simulator, but when I actually run the game on the quest it doesn't work. It seem like my wall doesn't render depth on quest, and I don't think the post process material runs either since mobile HDR is disabled.

Hi!! Do you guys use the forward renderer or deferred? I would want the performance gains of forward but I feel like for a solo dev the workflow enhancements of nanite and lumen are so good!! If you use deferred renderer, do you find the performance acceptable?

[rocky nexus]

if your targer is 4090 you can use all of that for vr i guess

[sacred nacelle]

thanks y'all. My main thing right now I can't figure out is that I want to use lumen and nanite less for graphics and more for creative workflow. I want to be able to sculpt assets in vr and not have to make multiple versions for LOD, and also potentially gain performance by using nanite?? Also, lumen would allow me to be so creative with lighting, shifting lights and changing things and not having to bake every time?
I'm a noob so not sure if I even understand everything correctly - like maybe with forward renderer there is a workflow where I don't have to make multiple LODs and bake lights?

Do you got hand tracking working in a packaged game? I`m using this plugin btw:

Check everything: Does it work in a packaged game? Correct Android SDK / NDK versions? Disabled all OpenXR plugins? Enabled Meta Plugin? Enabled Hand Tracking in Project Settings / Meta Plugin? (Hands Only / HIGH / V2) Using a proper data cable with enough bandwidth? (I think you can check this in the Meta Quest Developer Hub Software for Windows) How do you put on the headset? There is a bug, where you should wait for the VR preview window to fully load before you put on the headset, or it won`t show hands. Also my problem was my Ultraleap camera interferring with the OpenXR layer.
