Good day! I'm learning VR and Unreal from scratch and I went through older posts here. It's a problem related to the new VR template in 2.7. I need box triggers to work. In an older post from vr_marco here the problem has already been pointed out: The default player actor has no collision sphere. Here's the problem with the 2.7 template: The VR Pawn is in the starter content but not in the project outliner. It somehow works, I even did a Quest build where everything seems in working order. However, as soon as I add a VR Pawn with the aim of adding collision to it everything breaks. Do you have any hints?

[sonic lake]

It shouldn’t break, in any case use overlaps and not collisions. They are enough to make the trigger work.

[exotic basalt]

Thank you again for a world-record fast answer! 👍 I'll dive into that. This really helps for looking in the right places.

[dreamy ivy]

Hey everyone, I've had a lot of messages and requests to make a tutorial on how to create two handed weapons inside the new UE 4.27 Open XR template and in UE5. So here it is. I build onto the current template so it should be pretty easy to follow along.

I hope it helps you all out. Let me know what you think of it.

Link to the tutorial here: https://youtu.be/YVoftYIjU_U

[haughty pewter]

Hey there good people. Can someone help me out with something? I'm setting up an IK system for my VR Player, It was working fine when my player was a pawn but i changed it to a character for c++ and multiplayer reasons.

My character looks like this, but his feet should be on the ground. It has something to do with the capsule component, what should i do?

[royal wadi]

General VR question here that I'm hoping somebody can help me with. In a lot of VR games like Pavlov and Into The Radius, when the player presses the menu button, it loads up a menu scene that is separate from the actual ongoing game. This helps avoid having to mount the menu to the player's wrist or having the potential for menus to overlap the environment. Does anyone know what best practice is for this?

I have an idea on how to do this (I've tested it and it works at least in a single player scenario), but I'm not sure that this is correct, or how it would work if I decide to make my game multiplayer. I have a blueprint actor that contains the menu scene, widget actor, and a simplified player pawn with widget interaction components. I have this blueprint hidden beneath the map on each level. When the player hits the menu button, it finds this BP, pauses the game, and possesses the menu pawn.

Does anybody have thoughts on this? Is there a way just to do an overlay similar to the steamVR or oculus menus? I'd appreciate any guidance anyone can provide.

[ashen knot]

Hi guys, has anybody tried the new VR template in 4.27(OpenXR plugin) with WMR hmds? I have an acer wmr headset, and I cannot even get the play preview to work on it without using the Mixed Reality plugin or the SteamVR plugin. All I get is a black screen on my hmd. Any suggestions?

[cyan chasm]

Hi, I’m trying to build and run a VR simulation with the AirSim plug-in but it crashes. I’ve properly set the AirSim plug-in and it works without VR. Maybe I miss something. Any guidelines?
Moreover I found this advice, but I don’t know where to add the -vr argument

[dreamy ivy]

I created a tutorial showing how to create a dynamic pointer to work with the new 4.27 and ue5 template. https://youtu.be/Onnz9sv2dw0

[upbeat eagle]

Anyone try shrinking vr player? Had a cool shrinking mechanic I was thinking about prototyping but I’m wondering if it’s even possible with vr in UE

[zealous torrent]

hey everyone, anyone ever have the issue in 4.27 with open xr controllers not lining up with the physical controller? i know the tracking center was moved to the palm but it still feels very incorrect. im using index controllers and the offsets are quite noticable

[zealous torrent]

i think so, as long as you scale your capsule down it should work, you can then change the eye spacing using this node to make you feel bigger or smaller

[upbeat eagle]

Cool ill give it a try. Thanks. Hows the game coming along?

[zealous torrent]

getting there more or less, trying to update to OpenXR but so far its being a huuuge pain lol. the built in controller models arent lining up with the real world controllers and its driving me bonkers lol

[upbeat eagle]

yeah for oculus they are rotated 90 degrees and location off a bit. Also with open xr for some reason the buttons only give positive input for some reason. I held off on updating for now lol

[zealous torrent]

oh? like joystick inputs arent giving proper values?

[upbeat eagle]

no just the buttons. The A B X Y buttons. I have them set up as pos and neg axis. But it only gives positive. Disable openxr and just use the oculus plugin and it works fine lol

[zealous torrent]

oh i thought the face buttons were binary, do they actually have capacitive features?

[upbeat eagle]

they are as far as i know but you can still use them as an axis

just like you can with keys for an axis

[swift forge]

Hello. I've used this setup to pause VR game (Oculus) when HMD not on the head. But can't find a solution to pause game when menu button pressed. Any advice?

[upbeat eagle]

idk if you should be binding events on tick like that

[jovial hamlet]

I was wondering, how do people record trailers / screenshots for native Quest games?

I guess Quest would be fine with taking high res screenshots natively, although it would not be the most convenient setup. But how do you record a video? Is there a simple way to make desktop rendering look the same as Quest rendering? Or do you try and approximate the look?

[wheat holly]

One thing that comes to mind is maybe just doing it in the editor? I would be surprised if you can actually get high quality footage from a Quest it self.

I've also seen trailers with third person perspective shots and my guess to how those are made would be that they record the game in some way and replay that in the editor with a different camera that can also render in a higher quality than the Quest. But that depends on how your game works / if you want that I guess 😛

[jovial hamlet]

Well yeah, doing it from the editor would be the best way to do it, but desktop rendering looks very different from Quest rendering
Camera setup / actual recording is not the problem, I don't know how to reproduce the Quest look on the PC

[wheat holly]

What are you referring to with "Quest Rendering" though? The graphics in the game it self? Because you can change that in the editor, there's a settings menu for all graphical options such as shadow quality etc.

[jovial hamlet]

Even when everything is unlit, it still looks different in SM5 vs Vulkan Mobile

[wheat holly]

Maybe try this option? Although not sure if your exact option is listed in here, this isn't a Quest project I just grabbed so I can't tell for sure. But obviously you can take a look your self 🙂

[jovial hamlet]

yeah, I tried that before
at least it uses the same feature level in the shaders, but the final color is still different, so maybe I'm missing some postprocessing

left is native on Quest, right is Android Vulkan preview

[wheat holly]

I remember having the same problem with my packaged builds for the very first time but instead for PCVR, in my case I changed all kinds of settings to match them up which I think changed the packaged build rather than the preview which may not be so handy here 😅

[jovial hamlet]

just you wait for the update 😉

[wheat holly]

The lighting effects?

[jovial hamlet]

thanks! all lighting is faked with unlit materials, that was a lot of fun haha

[wheat holly]

Oh you actually played the game, ah alright xD

[jovial hamlet]

for context
looks similar on quest, minus the bloom ofc. Everything is unlit, lights and shadows are all fake (unfortunately shadows didn't make it into the megajam submission, but you have to cut something)
ah, and no textures as well, just some noise on the glowing thingy

[untold crescent]

We didn't know as well. First time playing with somewhat complicated shaders except for the logo lol

[jovial hamlet]

I guess we'll need to dig deep and do a proper study on how emissive materials are being rendered on Quest vs Vulkan Preview vs SM5. Unless I'm missing something obvious and all the difference is in the postprocess.

I at least suspect they handle emissive materials with >1 emission differently.
Also it might be possible to generate LUTs to make them all look more similar.
Haven't played with it myself, but oculus docs claim that vulkan subpasses apply LUTs in 0.6ms on Quest.
(maybe such LUTs already exist? anyone?)

but we are just starting, so it's probably something obvious

[urban niche]

Hey! Sooo. I am working on an archery VR game and I was wondering how I can get an arrow to respawn after they pick it up! I am using the handsvr template!
Thanks in Advance! (P.S: I already have the bow, arrow, and map!)

Ping me if you respond please!

[zealous torrent]

anyone know the best way to create motion controller filtering using blueprints?

like smoother motion

or interpolating

[sturdy coral]

@zealous torrent I think mordentral's plugin has the same filter the vr editor uses (1€ filter)

[tired tree]

they have a few different, but the 1 euro is by far the best yeah

[zealous torrent]

I have a clean project of 4.27. there isnt any residual steamVR stuff to my knowledge. should your plugin just work with 4.27? @tired tree or is there some C++ stuff that needs to be done?

[tired tree]

it would just work if compiled, but if you know how to make a c++ library you could pull the smoothing out

or for that matter, run some naive smoothing on something that you have follow the controllers on tick

and not hard lock to them

[zealous torrent]

Ah i see, It wasnt liking it when I tried building it as an engine plugin. putting it in the project plugin folder worked lol

[tired tree]

its better not at engine level

since it actually overrides some core engine level classes

project by project is smarter

[zealous torrent]

is there a proper guide to build through the IDE?

[tired tree]

https://vreue4.com/documentation?section=installation

[zealous torrent]

ah sick! thanks, this is much easier to follow lol

[jovial hamlet]

okay so apparently TIL that color spaces are a thing that actually matters and what a rabbit hole it is
even if it is not gonna solve all my problems, at least it seems like a step in the right direction

[lucid comet]

@swift forge

and you should use something more like this for the hmd on/off

[zealous torrent]

Is it possible to get finger curl and splay data for index controller using OpenXR?

not sure where the node is if there is one

[worn zenith]

hello

there

i have a doubt

i want to make vr games

but dont have one

can i create it?

[forest vector]

hey, have anyone used UE4.27 to binding the SteamVR ?

I am fail to bind.

[tired tree]

@zealous torrent you can GetMotionControllerData and it will provide a list of finger bone transforms if the tracking extension for openXR is active

however its a full transform, not just a curl / splay value

i have a C++ reference for posing and gesture detection from that in the OpenXRHandPoseComponent

[tired tree]

in the valve discord they were talking about some engines aproximating the curl values from that data

but not entirely sure how they would do that with gloves and the like having splays and the different hand setups of different apis

so not expecting it to happen

[marble frost]

Is it possible to switch off left/right screen of the hmd programmatically? Possible use case: shutting off 1 eye for VR sniper rifle

[quick dirge]

Maybe you can set a different texture on a stereo layer for a specific eye. But I'm no expert.

[wheat holly]

That sounds extremely disorientating 😅

[radiant garden]

I think you'd run into usability problems with this. If you go this route, make it so the player can choose which eye is covered.

Everyone knows about hand dominance, but people also have eye dominance. Being forced to shoot with your non-dominant eye is like being forced to write with your non-dominant hand.

[wheat holly]

If one of my displays went out I would legit think my headset broke, I would just quit the game to see if it actually still works.

[radiant garden]

Are there some recommended guides for lighting in VR?

My lighting is really washed out. Most the docs and videos I find about lighting is all the fancy toys us VR peeps can't use.

I'm also pouring gasoline on my situation because I'm doing a completely destructible voxel environment.

So baked lighting is out.

I've honestly considered turning lighting completely off and using emissive only.

[marble frost]

Thanks but I am not looking for design inputs, just wanted to know if it is possible or not

[upbeat eagle]

Whats best to use?

I think on clicked does not always work for me for some reason

[warm idol]

Hello Friends! I am unreal beginner and wanted to learn VR Oculus development, firstly from Documentations, i have 4.27 version and was reading also 4.27 version doc.
I cant get controller button nodes as its displayed in documentation.
First picture is my screenshot, second is from UE Documentation.
There is link: https://docs.unrealengine.com/.../OculusHowTo/SplashScreens/
What am i doing not right?

[swift forge]

Thanks for advice. I made this set up. When HMD on/off or on head or not game is paused. But when I press Oculus button it still not working, games continues. Made through Event tick

[fair timber]

Hey guys. I've been messing around with VR scouting for a while and using Unreal for rudimentary previs for sequences we shoot on feature films.

I've recently had a request though for the director to get more involved with with the VR side of things.

Am I right in thinking that the only way we'd be able to live edit a project as well as have the director interacting with a headset on. Multi user editing with two PCs?

There would be no way to use a single PC?

[sonic lake]

@fair timberyou can run two different VR headsets from one (very beefy) PC. Watch this: https://www.youtube.com/watch?v=Fi_OpRw4KwY

[fair timber]

@sonic lake Thanks cool to know that that's possible. What is be looking to do though is have VR mode deployed and still be able to work with and edit the project on the same PC.

I'd*

Deployed is the wrong word too. Activated.

[tawdry bough]

I’m trying to make the default VR controller grab a ragdoll

I have tried adding a socket to the torso and putting a collision sphere in that socket, but when I ppgrab it, the controller grabs the collision sphere but it doesn’t take the ragdoll with it

Is there any way I can make the collision sphere and ragdoll stay together?

[sonic lake]

@tawdry boughthe ragdoll is simulating physics while the motion controller is moving kinematically (following the tracked device), so you need to use a physics handle or a physics constraint to attach your ragdoll to it.

@fair timber what will you be editing in VR? The scene?

[lucid comet]

Everything before the last branch on the right should not be in the tick function and should only happen once when initializing (on begin play or something similar)

[nimble edge]

Anyone worked with the Vive Focus 3?

[nimble edge]

You're calling an Axis, not a button input.

[nimble edge]

Meaning, that Axis Value is a value of 0-1 of how pressed the trigger is. It's firing constantly. If you want Press/Released, you need it set up as an Action

(you set this up in Project Settings > Inputs )

[jovial hamlet]

okay, so we've spent two days tinkering with built-in tonemapper shaders and managed to trim it down from like 200 instructions to 15 instructions

now we can do "filmic" tonemapping on oculus quest when all materials are unlit
so now quest look matches PCVR look pretty closely, whereas before it was... different to say the least

here we disabled stuff like bloom and fixed the exposure for a more fair comparison, but you get the idea

man quest development is hard
but a lot of fun

now to learn about vulkan subpasses
I guess it should be possible to do basic tonemapping this way for lit materials too
does anyone have any pointers on how to do custom vulkan subpasses in unreal? 😅

[radiant garden]

That is amazing!

Are you using all unlit materials?

I'm trying to figure out how to light things on the Quest. It's so hard. Everything is way blown out.

[jovial hamlet]

yep, and for now we just slap a material function with this tonemapper at the end of each material
there must be a better way to do it, but it works for now lol

[radiant garden]

Is the tonemapper setting emissive color for the material?

[untold crescent]

Yeah, I thought it might be related to your issue. Maybe you'll get a proper preview in editor if you disable tonemapping

[jovial hamlet]

yeah, our setup looks like that, but I'm not sure if I'm ready to recommend it yet haha

[radiant garden]

I just starting learning about UE4's lighting system last night. Is tonemapping related to the exposure settings? And are the exposure settings in the post process volume?

[jovial hamlet]

we are just learning too, so I don't think this is a good advice

[jovial hamlet]

as far as I understand it, tonemapping basically maps the color from the values that you get in your materials to the screen color space; it is usually a part of post processing
and exposure is a separate topic
the color management livestream is a good overview of this stuff

and the filmic tonemapper feature highlight stream was great too

[untold crescent]

Yeah, it's set in the postprocess volume under Film settings. There're cool interactive comparisons for different parameters:
https://docs.unrealengine.com/4.26/en-US/RenderingAndGraphics/PostProcessEffects/ColorGrading/

[radiant garden]

Awesome! I will definitely check these out

This is PIE on the project I'm taking to VR. It's super washed out everywhere. I changed exposure on this way way low last night to get the color a little closer:

In my authoring tool, it looks black

[sturdy coral]

@radiant garden probably a gamma problem, are you doing it all with vert colors?

[radiant garden]

Essentially yes. Only setting the Base Color.

I was able to replicate the same look on the building minus the window color with a single color node going directly to the BaseColor

I set the color value to the same code as in my non-UE editor (magica voxel in this case)

So I know the color values are coming across correctly, it's something I'm doing weird with lighting

The lighting is a basic static light source, static skylight, and post process volume

I'm certain this is coming down to my inexperience with UE4

[sturdy coral]

what does it look like in unlit view mode?

[radiant garden]

Unlit looks a lot closer actually

The bluish box on the left is notable because that is the standard cube in my graphics editor

[sturdy coral]

the only thing that should be able to change saturation like that is probably specular from skylight, if the base is pure green and red and not at all desaturated

[radiant garden]

Yeah the base of the building is super saturated

[sturdy coral]

is that pure 0,255,0 green?

[radiant garden]

The cube on the left has rgb values 153 204 255

Not pure green, just a sec and I'll get it

102,255,51

I'll switch the colors to more pure spectrum, red, green, and blue and test again

[sturdy coral]

before base color try putting the color into a power 2.2 node

[radiant garden]

That sounds familiar, is that the conversion to sRGB?

[sturdy coral]

yeah, close to it

[radiant garden]

Wow. Now it is dead on in unlit.

[sturdy coral]

yeah, so it is a gamma problem

[radiant garden]

Awesome, thanks for helping me with this

I have some formal training in GPU programming, but it's quite dated at this point

[sturdy coral]

np, I'm not sure where you should put the fix

[radiant garden]

I haven't learned much about sRGB, etc yet

In the gif I'm doing classic texture packing to get the data to niagara

[sturdy coral]

if using proc mesh you may need fcolor instead of flinearcolor

ask on #graphics and they can probably tell where in pipeline it is going bad

[radiant garden]

Yeah makes sense to ask there, I was going to do that after sorting some other things first

[sturdy coral]

2.2 isn't exact srgb correction because srgb has some linear portion near zero, but it is close

[radiant garden]

Ok. I will research this a bit then ask in #graphics . Thanks for the help! That would have taken me forever to figure out.

[sturdy coral]

np

[upbeat eagle]

I had an issue something like this a while back and it was something to do with the camera auto exposure settings. Not sure if that’s what you are dealing with though.

[idle osprey]

Does anyone know how to get the motion controllers to show up in a non-VRTemplate project? I tried following what Victor said in the OpenXR Template video stream from a few weeks ago, but they just won't show. I also tried adding a small sphere as a static mesh on one of them, and widget interactors. Nothing shows up.

[idle osprey]

Nevermind! Got it...silly mistake.

[ashen vector]

When I am loading a level a sand clock appears on screen for a moment, is there a way to disable this icon somehow?

I mean in the packaged project, it is running on PC and this happens when changing levels.. I just want a black screen, but a clock icon appears.

[chilly pasture]

hey guys, anyone know any process of doing tcp dump on quest2

[trail cedar]

what was the mistake if you don't mind? adding a static mesh seems to cause that issue of all the other pawn components not working for me atm.

[idle osprey]

Well...turns out it's only half a mistake, half a problem. My silly mistake was I wasn't using my GameMode, so my Character wasn't loading. I figured that out when I added some logging for the position of the controllers and got silence....

The other half, the more serious 'problem' is ...now, let me point out that I'm building for the Quest and Quest 2.... When I build my project from a Windows box, it's fine. If I build it from a Mac, the controllers will not show up. Same code, same project.

I haven't checked to see if there's a size difference in the APKs yet.

[formal ridge]

Hey folks, so I’m packaging a project for shipping and I’m not sure this morning what I touched, but I’ve completely lost the ability to move my hands in VR they are stuck praying, does anyone have any quick insights on areas for sanity checks regarding this?

Launching the editor now to grab screenshots of my settings for the motion controllers

[lofty iris]

could be a collision problem. also make sure you spawn your player with its feet at zero Z axis somewhere outside the actual level, delay and then teleport him to your start position. @formal ridge

[formal ridge]

It’s a bit more complex than traditional VR player characters, this is my player BP, it’s actually a third person character mesh which I’ve added a motion controller onto, previously I had it working before I had to fix a different bug, I touched something and it busted my ability to move the hands

These are the class defaults for each of the different areas of the motion controller / motion controller pawn

[formal ridge]

I think it’s a setting I unticked as it was previously working

[lofty iris]

hm there was somthing with the player index causing issues, but the 4.27 update fix it. but you use the old one I guess.

[formal ridge]

Only using hands for widget interaction and yeah I’m on 4.26 it’s too far into the project to migrate sadly

[lofty iris]

sorry man, maybe someone else knows, but double check collisions and try spawning it outside or on an empty map.

[formal ridge]

I’m giving a few adjustments a shot

But yeah if anyone looks at the above images and is able to identify the settings issue please tag me!

[lofty iris]

Auto possess player is disabled on motioncontroller maybe that?

[formal ridge]

Yeah I’m testing that now but I can’t remember if I disabled it prior or not due to conflicting controller issues with the third person character

Sadly I have to package it for shipping each time to test so it will be about an hour before I’ll have that answer

[glad ocean]

I've made an app using a plugin that accesses the local storage on a oculus quest 2 to play 360 videos. But for some reason it runs at around 33 fps. The entire scene only has 4 actors and I've tried optimising it by removing tick events wherever possible. But low fps is still an issue.

Does anyone happen to know whether accessing the local storage is a demanding task?

the gpu is on 29ms even when a video isn't playing? It's a black empty scene. Does anyone know what might be causing this?

[formal ridge]

Fixed my issue it was the possession
Broke my steam subsystem though without even touching it 😅 so onto the next bug in this rabbit hole 😁

[wheat holly]

You'll need to look at what is actually causing your game to run at low FPS, we can't guess the problem 😛
I would suggest looking into the GPU profiler if you're sure that's what the problem is.

[glad ocean]

I'm using a plugin that accesses the local storage of the quest 2 headset to play 360 videos. Do you happen to know if that is a demanding task?

[wheat holly]

Reading files (videos) especially big ones can take time and is overall not the cheapest operation, I'm not sure what your plugin exactly does though. If it's a high resolution video it could also be the case that the quest can't render it fast enough regardless of reading the file it self, it's after all just a mobile device. So if you see your GPU giving a spike consistently look at it with a profiler, for all you know it's something else 🤷‍♀️

I see you for example have a Post Process Volume as well, may as well be that a setting in there takes a good amount of your performance away.

But again, we can't guess what the actual issue is without you looking at it.

[glad ocean]

https://www.unrealengine.com/marketplace/en-US/product/video-player-360-2d-180-360-stereo this is the plugin in question. The gpu being on 29ms is a constant issue. Right from when the app starts and no video is even being played.

The PPV is there because I read online it helps performance to place one and turn things like bloom etc off

[idle osprey]

I've got a question for all the Lefties (like me) out there!

Do you prefer to use the Rightie's movement controls (left-hand steers, right hand turns) or would you rather have that swapped?

[radiant garden]

It sounds like you aren't using source control. You'll want to remedy that ASAP. Among other things it is great for regression testing issues like this. You can revert to earlier known stable states for testing.

[tired tree]

@idle osprey option to use either, not that hard to setup input to allow for that

[idle osprey]

That's what I was thinking. I'll just have a bool for swapping hands for movement.

I'm so used to the Rightie way now, it doesn't matter...but still, I'd like to provide as many options as I can.

[rancid bolt]

Sup peeps! Anyone know how to fix Nav mesh problems? My NavMesh doesn't seem to want to appear even though collisions are off and I placed a pefectly sized NavMesh Bounds Volume

SIKE I FIGURED IT OUT

NavMesh doesn't seem to like planes (wether with or without collisions). Use cubes instead -- This applies to indoor environments, idk if it's also the case with outdoor ones

[winter needle]

Shizz all trailers about Ar glasses are kinda fake nothing robust for ar yet and unreal support for ar is almost non exist

[formal ridge]

Found the primary issue but not sure what solution there is here is the post I made in the sub system area

Steam Sub System

Steam Sub System works with Launch(Default), but when choosing one of the VR Launch options, I have 4 different launch options set, none of the VR Options have the Steam Sub System Enabled.

Again, the Steam Sub System Does Work with Launch(Default) Desktop Mode, Playername gets configured, and players can Host / Join. However, when say Launch Oculus SDK VR App or Launch SteamVR App are used, the title will not register that it has a working Steam Sub System.

Here are supporting articles of developers having the same issue
https://steamcommunity.com/app/358720/discussions/0/1353742967809614133/
https://answers.unrealengine.com/questions/675889/steam-initialization-problems-in-vr.html

I've tried disabling SteamVR Home, however, this no longer works as a viable option.

I've spent the last 72 hours attempting to figure this out(created 9 different builds to attempt to find the fix), searching all of google, forums, discords, and beyond to no avail.
The only two articles relevant are the ones above, but I've gone through thousands of topics related to Steam, Steam Sub Systems, Steam Documentation, UE4 Documentation, also someone recently vandalized the Wiki page for all of the VR Documentations, which has hindered all VR Developers recently in the last month. There is even a post about this within the Steam Dev Community.

This is on UE4 4.26 Shipping Build for the title as additional information!

[tired tree]

@formal ridge have you tried in packaged?

its normal for the engine to not load the steam subsystem outside of stand alone

also that steamvr home issue is from 2017, I remember when it happened

shouldn't be the case anymore

if your packaged version isn't loading the steam subsystem then its just a misconfiguration on your end

[formal ridge]

Aye, I have it packaged for shipping

I’ve packaged 9 different variations

It works packaged if ran as launch default(opens as a pc game)

But when launching with SteamVR App launch option or even Oculus VR launch option with shipping build it doesn’t register the subsystem exists

And to clarify

The same build used works in desktop play, sub system shows properly, just when VR launch is used, it doesn’t work

So I know my configuration works in terms of functionality just not with VR 😤

When packaging a VR project for SteamVR you should be using windows yes?

[formal ridge]

~

[tired tree]

yes, but I will note that I have dozens of users running steamvr and steam concurrently on 4.26 just fine

what does your log say? just attempting to init and then shutting down the subsystem?

[formal ridge]

When I package the logs read off like normal I have zero errors, the sub system initiates and is working, I’ll have to figure out how to pull the logs from the latest packaging

[tired tree]

i'll take this to PM, its likely vr unrelated in the end

[formal ridge]

Copy!

[swift forge]

Thanks. Seems it work except media. My experience plays video after user choose one. But simple Player's Pause doesn't work.

[lucid comet]

Yeah. I had to set the play rate to 0 on my media player to pause it

[swift forge]

Ha. That's an idea. I'll try it. Thanks a lot!

[idle osprey]

I've got a C++ problem I can't figure out. When I set up my VRCharacter in blueprint, I set my VR Root to -88 and the Camera is then a child of it. This works fine if I do this in Blueprint. But when I set this up in C++, my floor is always way below my real floor. ```c++
AVRCharacter::AVRCharacter()
{
// Set this character to call Tick() every frame. You can turn this off to improve performance if you don't need it.
PrimaryActorTick.bCanEverTick = true;

Have you checked if

        UHeadMountedDisplayFunctionLibrary::SetTrackingOrigin(EHMDTrackingOrigin::Floor);
```actually runs? The docs mention "using" which makes me think if your headset is not actually actively used it won't work.

[ashen vector]

I am working on a Rift application but it doesn´t look as good as the editor, I know the resolution is a factor here, but is there a way that I can force some quality enhancements to the HMD and make it look better?

[modest kestrel]

When you say editor, you mean VR preview in the editor vs a packaged build? Also, a few screenshots/examples could help people understand better what the problem could be

[ashen vector]

I am sorry I can't share anything because of NDAs 😦 but no, I mean the edito window on the PC screen, I know is not the same as the optics in the HMD but I feel I am missing some configurations that can make it look less bad.

[modest kestrel]

Mm without seeing it it would be difficult to tell, this is a blind shot, but something that in my experience is a lot more noticeable in the headset vs the flat screen and could make the same picture look worse in VR is the antialiasing, try increasing it to see if you see a difference

[ashen vector]

how can I do that?

one of the things I tried was increase the pixel density, but it didn't help that much and performance was not good. so I revert that back.

the most noticeable things are as you say, edges not smooth enough so I guess antialiasing will help, just not sure how to configure that..

Also contrast is not as good, and most things are smudgy or not crisp enough.

[modest kestrel]

there's a command that you can introduce to change that in game, I'm looking for it

r.MSAACount

assuming you are using msaa of course

[ashen vector]

I think I am..

mm no I was wrong..

[modest kestrel]

Mmm OK, so that could be the issue, run the game and use r.MSAACount 4 in the command line

you should see a difference

TAA is basically VR Myopia experience 😅

[ashen vector]

I guess I should change the anti-aliasing method first?

[modest kestrel]

I think the command should do it in runtime, that's only the default method

[ashen vector]

ok

[modest kestrel]

but yeah, you can change it there

[ashen vector]

let me try it

mm yes I think it is slightly better. thanks. anything else you can think of?

can I go higher than 4?

[modest kestrel]

I think so, but antialiasing is performance costly, so you will see a big drop in GPU times

btw, you can switch back to TAA in runtime with the headset on to compare by using r.MSAACount 0

and r.MSAACount 1 turns off antialiasing altogether

[modest kestrel]

As I mentioned, without seeing it it's hard to know 😅 , but I would recommend you to check the Unreal documentation for the recommended settings for VR, if TAA was on, it's possible another undesired setting is also on that could be hindering the experience

like idk, forward rendering (which should also be turned on)

[ashen vector]

mmm it is not turned on, but I am afraid it will break the look that I already have :/

[modest kestrel]

hehe yeah, it could change the way some things look compared to referred, but it's the recommended method for VR, so you should see a lot of improvements in other areas, so the change in my opinion should be definitely worth it

[ashen vector]

I think I was wrong, when turning msaa it looks like no antialising.

will make a backup and try to change to forward rendering tomorrow.

[modest kestrel]

👍

[ashen vector]

thanks

should Forward rendering should be activated even for a PCVR experience?

[modest kestrel]

It's recommended for any Unreal VR experience (not mandatory tough) https://docs.unrealengine.com/4.27/en-US/TestingAndOptimization/PerformanceAndProfiling/ForwardRenderer/

[idle osprey]

Yes, it's executing the code.

[idle osprey]

Solved...another silly mistake.

[trail shale]

After trying to get level streaming to work without experiencing big hitches (I have plenty of time so I could make it load 'slower' but smoother so there wasn't a hitch on the current level when another is streaming in) - I'm giving up and **switching to just using a blocking load for VR/ - so I need to use a VR splash screen instead - **

I'm assuming the docs are a good enough reference to accomplish this right (using Steam VR) - I mention the level loading in case someone magically knows a way but every time I bring it up someone tells me it's an engine limitation or something

[arctic saddle]

does "AnyKey" on the input work for VR controls like the headset being idle?

[radiant garden]

I thought the point of level streaming was that it was suppose to prevent hitches. Is there something special about VR causing issues with this, or are there inherent flaws with level streaming?

[jade kettle]

Is there a way to launch in VR mode if you connected your headset after startign up UE4 Editor?

Without restarting the editor

Asking for a colleague (not me) who accidentally borrowed his colleague's headset without plugging it back in (once again I didn't do it)

[trail shale]

I don't think it's related to VR - when I don't have the headset switched on, I have a boolean that disables the loading of any VR aspect of the project, the hitches still occur there - what I'm doing the VR loading is it swaps you completely out of the game, back to the Steam VR environment, so you still are moving around smoothly

best work around I can think of, but I'd be very grateful to anyone who can help me with hitches

[real needle]

is there any documentation/talks about ProjectEverywhere (Unreal geospatial AR sample)

[daring pasture]

Are you packaging out and testing? From my experience the hitches don't occur in packaged builds

[trail shale]

mine do but I think my settings are wrong, particularly the loading async not being ticked

[trail shale]

Also, does Steam VR block dialogue boxes sent from Unreal?

[vast thunder]

Anyone here have a valve index or htc vive that could litterly just test if they can walk using joystick in my game

I will send google drive link with packaged game file. I just need to know if you can move

IF you dont and you know anything can someone explain why this input bindings will not work?

@hallow knoll I know you are usually active in here hopefully you can help

My game SafeZoneVR was trending on steam and has nearly 20k downloads in one month so it would be great if I can finally add support for index and htc

[untold crescent]

dm, I have a vive pro
Edit: going to get some sleep, but can help after that

[idle osprey]

Nice trailer video. Did you do the whole thing in blueprint?

My latest problem is I can't seem to add motion controllers to my Character. When I start the app on the Quest, it just exits. I'm not seeing anything obvious like a null pointer in the logs. ```c++
AVRCharacter::AVRCharacter()
{
// Set this character to call Tick() every frame. You can turn this off to improve performance if you don't need it.
PrimaryActorTick.bCanEverTick = true;

// Create the objects we'll need
VROrigin = CreateDefaultSubobject<USceneComponent>(TEXT("VROrigin"));
Camera = CreateDefaultSubobject<UCameraComponent>(TEXT("Camera"));

LeftMotionController = CreateDefaultSubobject<UMotionControllerComponent>(TEXT("Left Controller"));
LeftMotionController->SetShowDeviceModel(true);
LeftMotionController->SetTrackingSource(EControllerHand::Left);

RightMotionController = CreateDefaultSubobject<UMotionControllerComponent>(TEXT("Right Controller"));
RightMotionController->SetShowDeviceModel(true);
RightMotionController->SetTrackingSource(EControllerHand::Right);

UWidgetInteractionComponent* LeftWidgetInteractionComponent = CreateDefaultSubobject<UWidgetInteractionComponent>(TEXT("Left Widget Interaction"));
UWidgetInteractionComponent* RightWidgetInteractionComponent = CreateDefaultSubobject<UWidgetInteractionComponent>(TEXT("Right Widget Interaction"));

// Attach all the objects to their locations for a VR Character
VROrigin->SetupAttachment(GetRootComponent());
Camera->SetupAttachment(VROrigin);
LeftMotionController->SetupAttachment(VROrigin);
RightMotionController->SetupAttachment(VROrigin);
LeftWidgetInteractionComponent->SetupAttachment(LeftMotionController);
RightWidgetInteractionComponent->SetupAttachment(RightMotionController);

}```

Is there a subsystem I need to add like I do for the HMD and UMG?

[surreal marsh]

Hi guys, got a quick question, we are building pvp vr games. wondering what's the best voice chat tool for unreal engine?

[real needle]

trying to deploy on hololens 2 from Unreal 4.27. getting this:

AutomationException: Device connection failed: Requesting operating system information

using both ip of usb connection or wifi, same error.

hololens device is visible in device manager

[idle osprey]

Solved this one, too. I saw my BP_VRCharacter was referencing VROrigin(VRRoot). I'd renamed VR Root to VR Origin. But apparently cleaning and rebuilding the project from source wasn't enough -- something was stuck in the BP. So I deleted the BP and re-created it and my app is working now.

[hallow knoll]

@vast thunder you need "_X" and "_Y" at the end of the axis input mappings

[spare yew]

Still getting LogGoogleARCoreAPI: Error: ArSession_create returns with error: -2 with my Android 11 Device after the 4.27.1 Hotfix 😦

Anyone had any luck with ARcore on Android 11 with the hotfix? It listed UE-123593 Update ARCore SDK to 1.22.0 and I assumed this would have fixed it.

[spare yew]

I'm glad we don't get many AR projects in anymore or else I'd be on the chopping block for convincing the company that we didn't need to rely on Unity for AR projects 😫 This lack of support for ARCore is starting to stress me out

[vast thunder]

Yes I did, thanks for the compliment, I do trailer work for freelancing to so lmk if u need a trailer (:

[vast thunder]

What do you mean by that?

[wind yacht]

@spare yew Yeah I have no idea what's up >_< these black screens have been a nightmare for me

[sturdy coral]

Your axis name can't be like "MoveForward" "MoveRight", it has to be "Move_Y" and "Move_X"

it is due to steamvr's 2d axes not mapping exactly to ue4, which does everything 1d mostly

it looks for _X and _Y on the end of the name so that it knows to map both to one single 2d axis in steamvr

[vast thunder]

Wow thanks much Charles

I looked everywhere on google and couldn’t find that along with vc

Surprised that’s not in ue4 documentation as far as I could tell

[twin elm]

does anyone else encounter the problem of the AR App developed with the unreal engine not opening in the Samsung Galaxy S series phone?

[spare yew]

Yup.

[wind yacht]

The example project for 4.26 had a lot of problems for me when I ran it on Android so I'm kinda bummed to hear it may still have problems with the new template in 4.27.1

[hallow knoll]

@twin elm @spare yew is that still the problem in 4.27.1? We updated the ARCore version just read your message further up

We were unable to launch on Android 11 prior, but after the update we didn't come across any issues

[wind yacht]

What is your version target set to? I'm wondering if that is my problem currently

[vast thunder]

Anyone got an index willing to download my game rlly quick and see if they can walk, I got the file on google drive ill share with you

or htc

should take about 2 min

[hallow knoll]

@wind yacht XRQA is targeting 24, and they also mentioned that the camera issue can be solved by enabling "Support Arm64" in project settings

We have the issue logged and are looking into it but hoping that can unblock you in the meantime

[wind yacht]

Thanks, I'll take a stab at it later today. I do have "Support Arm64" enabled but my target was set to 30. I'll try 24 and see if that fixes things overall.

[rancid bolt]

Anyone know how to fix this ?

I'm pointing at a specific spot (right blue line) and it seems to teleport me to another location (left blue thingy)

[tribal lintel]

check your nav mesh, press P in editor viewport to make sure green is covering that area, then check collision view to make sure something isn't blocking in front of you

[rancid bolt]

Nav mesh seems perectly fine and collisions are off

Btw thanks for trying tho (honest thanks, no sarcasm)

Plus the problem occurs all throughout the map

Like this :

[tribal lintel]

hey no problem 🙂 I wish that was the issue! is it happening everywhere in the map? can you teleport anywhere at all?

the next thing I would try is to go into your pawn, find where the trace is happening for the teleport (IIRC search for project arc to nav or something) and put a print string off the trace and try and print what your hitting with that trace

[sturdy mirage]

Is anyone in here able to get hand tracking for Quest working in the editor? I'm building from various different sources (including taking projects that should work) but am unable to see my hands in the editor, regardless of my configurations

Only way I have been able to see my hands yet was in a packaged build, and they didn't even have a texture

[rancid bolt]

I can teleport but rarely to the right location. As for the trace and other stuff, I'm new to VR so I'm not too familiar with it, but I will look it up. Thanks for the headstart

[rancid bolt]

Btw what does IIRC stand for? (Or what do you mean by it?)

[rancid bolt]

Have you tried copying from VR template and importing (or pasting) to your scene?

[spare yew]

IIRC = If I Recall/Remember Correctly

[rancid bolt]

Thank you

[sturdy mirage]

VR template does not have hand tracking enabled

VR Template only supports controllers.

[rancid bolt]

Ye I just noticed. Sorry 'bout that

Let me know if you find something though

[sturdy mirage]

The weird thing is I know something is picking up my hands since I can see the Home/Quest symbols when I turn my hands toward me but I have 0 model, not even the default hands

[rancid bolt]

https://www.youtube.com/watch?v=sSdpPtlEk20&ab_channel=Just2Devs

Have you tried this tutorial?

[sturdy mirage]

Yes, that's one of the tutorials I tried but something seems to be missing

I have found a project where I see the hands, now to find out what is missing/different

[wind yacht]

Gave it a go with still seeing a blank camera view. Works fine in 4.23 though with no changes

[rancid bolt]

OK so for anyone with NavMesh problems, here's some steps that've helped me troubelshoot : 0) Before starting, duplicate your scene and rename the new scene "TEST" 1) Are your collisions on or off? Turn floor collisions on and wall collisions on and replace wall collisions with nav modifiers. 2) Do you have a skybox or hdri? Try deleting it 3) Are your floors planes? If so, try replacing them by cubes. 4) Do you have a Recast NavMesh in your scene? If not, drop a Nav Mesh Bounds and it'll automatically make one (which'll in turn, recalculate your NavMesh) 5) Do you have groups of objects? If so delete them and check if they were the prob.

[rancid bolt]

Anyone know how to use this? (And where or how to plug it in the VRPawn graph)

[spare yew]

Can confirm enabling "Support Arm64" has finally fixed the issue for me! Handheld AR Template now launches on my Samsung Galaxy S10+

[wind yacht]

@spare yew can you share a screenshot of your settings for Android? I have a Galaxy S10 and am having issues even with Support Arm64 enabled

[spare yew]

They're just default, only thing I changed was Support Arm64

[wind yacht]

WHat is your target and minimum sdk set to?

[spare yew]

24

[wind yacht]

for both target and minimum?

[spare yew]

Yup

[wind yacht]

hmm ok I'll see what's up. I think I did that but still was getting issues

[spare yew]

Are you having trouble building or are you getting the "AR Session Create failed -2" error?

[wind yacht]

I am building fine, but when I run my AR session the camera shows just black

it worked fine in 4.23

[spare yew]

Have you tried tweaking privacy settings on your phone? Just a thought.

[wind yacht]

I can see but I'm unsure why it worked before and now dowsnt work

[spare yew]

Yeah that's not an issue I've had before (among the many)

[wind yacht]

i'll look at your suggestions and see what's up

huge headache

[vast thunder]

Ok so i have a really complicated question but to anyone who helps with an answer Ill tag you when I update my game next (currently has 20k downloads in first month)
Question, so basically I need to regenerate action manifest and controller bindings, I can do this in project settings but the problem is when I click the button to do so nothing happends, no output log text either

those the buttons I press and nothing appears in output log

Engine verion 4.27.1

I have tried disabling and reenabling plugin didnt work

same problem with another 4.27 project also, I need a fix asap so I can release index and htc support for my game (:

[eager pine]

Hey!
Does anyone have experience with having livelink data shared across network? For others to use the same tracking data
Got it working

[hallow knoll]

Thanks for following up with an update!

@vast thunder you can just add Index and Vive Keybindings in project settings in 4.27

[hallow knoll]

You can execute Set World to Meters anywhere and it'll work. VRPawn Begin Play works just fine.

[rancid bolt]

@rancid boltyou should be seeing the Oculus Rift in Unreal and be able to Play in VR. Did you install the Oculus software?

[rancid bolt]

Hey! Forgot to take the post out. Turns out the problem was the Start in VR checkbox. Thanks for answering tho

[sonic lake]

@rancid boltyes, that is a common pitfall. Glad you solved it.

[red grove]

Hi, I have GetTrackingOrigin() set to eye level and I correctly ResetOrientationAndPosition with EOrientPositionSelector::Type::Position on a click on a button, when I call OpenLevel, this settings resets to default or something else. Does anyone know 1) if setting changes in Headmounteddisplaylfunctionlibrary stay persistent across levels? 2) Is there some override for engine class so I can save this calibration? 3) Are there other better libraries for me to use. Thank you

[vast thunder]

I do not have a steam vr manifest file in my project config folder or when I package though

I need like a new one

If you could victor or anyone else just call me on discord that would help alot just a few min

Im in urgent need of help asap

[sonic lake]

@red grove what is preventing you from calling those functions (I guess you meant SetTrackingOrigin()) on Begin Play for each level you load?

[red grove]

@sonic lake I have two options, floor or eye level, I dont how that will help me

@sonic lake When i call resetpositionandorientation I get exactly what I want, hdm is reset and I know the cameras location is at 0,0,0 and its also in Mainroot (scene comopnent above it)

@sonic lake I thought that floor trackingorigin means that its calculated from floor, probably from oculus, but I might just know what its for 😄

[sonic lake]

@red grove what I meant is that you can automatically call the settings you need and the reset from your Begin Play of each level you load, there is no need to have the player do it with a button

Floor tracking origin is for most VR experiences where the player is standing / moving in the playarea and for which knowing where the floor is is key to the experience (and for safety reasons).

[red grove]

@sonic lake ok, but I need the player in position where he stands, if for example he loads another level, in that time he bends or sits, when the begin play function is called i will set wrong height

[sonic lake]

Eye level tracking is usually for seated experiences and for intermediate loading levels where it doesn't matter where the floor is

[red grove]

In the game im making it doesnt matter where the floor is, I just need the player to stand and confirm. Then the player is playing with expected experience

[sonic lake]

@red grove you usually manage that in an intermediate loading level. And you still give the option to the player to reset their position.

[red grove]

@sonic lake ok, now I have to find some docs on intermediate loading level, because that I havent done yet. Thanks a lot!

[sonic lake]

Basically it is a mini-level which you use to tell the player how to position themselves before you proceed to load the real level.

You can even detect the movements of the HMD and of the motion controller and proceed only if the player stands relatively still.

We do this in our VR platform to do an automatic "calibration" for a seated experience.

[red grove]

@sonic lake nice, using velocity of hmd and controllers its actually a pretty good idea. Id probably use moving average of those velocities to check it

[sonic lake]

exactly

[red grove]

but I just need them to stand

[vast thunder]

Anyone got any idea on my question ):

[red grove]

@sonic lake so just final question, if i use intermediate loading level, im able to share level metadata or properties?

[sonic lake]

you mean among levels?

[red grove]

yes

[sonic lake]

You can store what you need in your GameInstance

[red grove]

@sonic lake thanks alot 🙂

[sturdy coral]

no manifest you need to click

[vast thunder]

@sturdy coral nothing happeneds when I click that

that was my original problem

I checked output log and nothing writes when I click and of those 4 buttons

[sturdy coral]

check log for Error trying to generate action manifest

on thing you can really do is search around and find someone else with a common reason it might fail, or put a breakpoint on:

#if WITH_EDITOR
void FSteamVRInputDevice::RegenerateActionManifest()
{
    this->GenerateActionManifest(true, false, true, true);
}

and step through the code until you find where it fails

maybe make sure you have steamvr running and turn off all other HMD plugins temporarily

[sturdy coral]

also, try with a very simple project first like the built in vr template, try something like deleting the manifest if it comes with it already there and make sure you can regenerate it. If you still have problems there you know it isn't something specific to your project.

[vast thunder]

Ill do that rn

just tested on other 4.27 and same problem

The buttons dont post anything to output log

someone I talked to yesterday said same thing for their 4.26 project

I need to release the full vr support update asap and this is making me very not happy ):

[sturdy coral]

{
#if WITH_EDITOR
    FSteamVRInputDevice* SteamVRInputDevice = GetSteamVRInputDevice();
    if (SteamVRInputDevice != nullptr)
    {
        SteamVRInputDevice->RegenerateActionManifest();
    }
#endif
}```

[vast thunder]

C++?

[sturdy coral]

if (SteamVRInputDevice != nullptr) that means if input device not created because of another plugin, it won't run

I'm pretty sure

[vast thunder]

So what do i have to do

What other plugins would be in the way

[sturdy coral]

turn off the oculus plugin or launch with -hmd=SteamVR (latter might not work there have been various bugs over time with forcing hmd plugin)

[vast thunder]

Ok turned of oculusvr plugin

Im assuming that means game must be played now with steamvr open

no matter what platform

OMG IT WORKED

[sturdy coral]

you can turn oculus back on after

[vast thunder]

@sturdy coral you are a legend, where did u find the info for that I did like 100+ google searches

Bet!

Im posting a forums post rn for others, I couldnt find an answer anywhere and this has to have happend to others before

[sturdy coral]

@hallow knoll the engine should make it pop up an error dialog for that case, might have been supressed when that other annoying regenerate warning was supressed or something

[vast thunder]

Yeah me and my other friend got no output log entry

[sturdy coral]

I think it used to be if the oculus plugin was taking over then the steamvr input toolbar button wouldn't show up and that used to trip people up. Not sure about after it moved to Project Settings

[vast thunder]

I think this is something that needs to be passed on to steamvr plugin devs or ue4 devs

[sturdy coral]

this whole panel should prob be replaced with a warning if oculus or other hmd plugin is interfering:

https://media.discordapp.net/attachments/221799478364078081/898371471590686791/unknown.png

they closed all pull requests on steamvr now though so I think it may just not get fixed since everything is moving to openxr by default

[vast thunder]

Thank god for openxr

I got to do some reading on that

Does everything work rn with openxr? Like why couldnt I just do that rather then deal with steamvr api or is it not working yet for all headsets?

[tired tree]

openXR currently has some oculus platform issues

and anyone running through steamvr with oculus over openXR will just straight up not having a working application

its not translating correctly atm

[kind palm]

Does changing the open XR environment not fix that problem?

[topaz plank]

Oh ffs, they still didn't manage to fix the stereo layer issues for Oculus Quest in 4.27.1? Depth now works with Oculus VR plugin, but alpha is unsupported (black opaque background instead of translucent). And with OpenXR it doesn't work at all...

[neon geyser]

Hello everyone, there's been a big issue for a while now with UE 4.27, you can't use the VR preview as a client (no hmd orientation applied) which makes debugging really hard for an online game.

Could you give a little upvote to that issue?
https://issues.unrealengine.com/issue/UE-122229

[raven dome]

Hi so I’m wanting to buy these character models on unreal engine but it doesn’t show if I put steam vr support on but I thought that wouldn’t matter since you have to code it to your wanted movements if it was in vr can anyone please help me out don’t really wanna risk buying if it doesn’t work for vr

[spare yew]

Didn't realise until digging through the BPs that there was supposed to be a visualisation of the scanning plane. The material doesn't seem to work on Android - from my testing, it appears the "Get AR Texture" node doesn't work on Android but is also not returning an error meaning the fallback material is never chosen.

[spare yew]

Correction: texture sample type needs set to external. "Camera Image" works but the others do not.

[spare yew]

I'm going to assume I'm just doing something wrong. Would be nice to have some more concrete examples of how to use the various cross-platform AR features

[daring pasture]

@raven dome it's not really optimized, it uses like 20 separate materials on each character, so if you plan on using several in a scene it may cause some performance hits

[raven dome]

Ah that makes sense how else do you think I could get a character like that?

[daring pasture]

Outside of paying someone I'm not sure, there's not a whole lot of options out there for ww2 characters

[sonic lake]

@raven dome I don't own that asset, so please take this with a pinch of salt. Unreal has a powerful skeletal mesh optimization system through automatic LOD's, caching, baking of materials, etc. With some work you may be able to make those characters work in VR as well. One way to test whether it would work or not is to try out, for example, with one of the many Paragon characters which are available for free from the Marketplace. They are very detailed and run some complex Blueprints/Animgraphs as well, so if you can make one of them work reliably, chances are you can make also those above work. It also depends on your project, which VR technology you are targeting (PC/mobile), what else goes on in your level, etc.

[sturdy coral]

I think there is a texture baking tool somewhere in engine that can usually combine everything down to one material

[pulsar roost]

Hello everyone! Hope you are having a nice day.
I was wondering If we can walk in VR Mode 🤔 I am using virtual scouting interactors

[idle osprey]

I'm not quite sure I understand your question, but I think you're referring to room-scale VR? Where you can walk around in your play space and the headset properly updates your position. @dreamy ivy did a great blueprint tutorial of my VR movement system on his GDXR YouTube site for both UE4 and UE5. Physical walking and crouching (thanks to Marco!) work great.

[pulsar roost]

Oh I will take a look into it! I am pretty sure is that. I would like to walk in the space instead of always flying.
Thanks a lot!!!

[neon geyser]

Thanks to everyone who voted, it has been such a pain in the ass to debug clients those last weeks

[sonic lake]

@pulsar roostthere are various ways to move in VR.
Teleportation (which is what you may refer to as "flying") is widely used because it is quick, rather intuitive and it is known to limit the possibility to get motion sickness. The destination position is chosen by the player by positioning a target on the floor using the thumbstick. Usually the movement which is about to be performed is visually represented by an arc connecting the player to the target location.
** Locomotion ** is more similar to walking within the VR space. It is slower for the player and in some individuals it may induce motion sickness (especially if there a fast continuous rotations or accelerations). Usually you control the movement/direction with the thumbsticks on the motion controllers or by following the direction of sight, but there are other ways (for example by moving your arms back and forth). There are a couple of tutorials on my YouTube channel on how to switch from teleportation to locomotion (thumbstick controlled) for the old VR template. Didn't update to the new one yet.
** Snap turning or Snap rotation** this is a technique related only to rotations and it meant to avoid motion sickness for the player. Basically instead of turning in a continuous way, you turn by fixed angles (90 degrees = 1/4 turn or 45 degrees = 1/8) each time. It is the equivalent to teleportation but for rotational movements. I made a tutorial on this technique as well.

[idle osprey]

She's looking for a way to walk around while editing in VR.

[sonic lake]

@idle ospreyah, got it. That would be the "old" VR Editor then. Or a custom experience specifically built for that, as it is typical in ArchViz.

[idle osprey]

Yes...not really something that I'm that familiar with as I do most of my Unreal work from a Mac.

[sonic lake]

@idle ospreyyep, you are not giving up on that! 😉

Kudos to you on your perseverance despite the problems/limitations.

[idle osprey]

Nope, works fine...except controllers don't show up in a Mac build on the Quest...quite odd, but that's the only thing I know of that doesn't work.

[sonic lake]

Meaning the controller meshes don't show up?

[idle osprey]

Yes.

Same project built on a Windows machine, running on a Quest, the controllers are present. Build the APK from a Mac and they're not.

[sonic lake]

Weird. They should come from the plugin anyway. I am sure there is a reason. Any hint within the build/packaging log?

[idle osprey]

Nope. Nothing.

[sonic lake]

Is that using the new VR template?

[idle osprey]

And the models are present, I can see them in the editor. If I manually assign them as the mesh, they show up. But not letting OpenXR determine the headset and assign the right controller.

Yes, or doing it myself in C++

[sonic lake]

Ah ok. So they are in, but for some reasons they are not retrieved or associated by the OpenXR plugin.

[idle osprey]

My guess is there's an #ifdef in the OpenXR plugin.

Something about supported platforms.

[sonic lake]

Could be. Engine version?

[idle osprey]

4.27.1

[sonic lake]

ok let me check the source code

[idle osprey]

Well...4.27.0. I haven't tried in .1

I pinged Victor about it and submitted a bug.

But anyway, as I said, that's the only oddness I've found doing Quest dev from a Mac.

Since I'm going to be using UBIK in the end, it probably won't matter to me.

[sonic lake]

I am sure it can be solved. UBIK! Yes. 🙂

It has been a fun project.

[idle osprey]

Yes, I want to do full-body...animating the lower-body. Not sure how to do that yet, but I'll get there.

since I won't have foot trackers, animation is my plan.

It's what I did with Final IK in Unity.

[sonic lake]

The lower body is tricky without foot trackers. The kinematic chain is rather long and you would need a biomechanical model like we have in UBIK for the upper body.

Ideally you could use Deep Learning to devise the leg position from the overall movement and from the other sensors.

[idle osprey]

Seems a bit much for a Quest.

[sonic lake]

Once the NN is trained it is surprisingly fast. This is how hand tracking it is done inside the Quest.

Of course animation and a bit of heuristic are much simpler.

[idle osprey]

Yes. It's a challenge for another day, tho. I am learning about dynamic maze generation now and rewriting all my blueprint stuff in C++

[sonic lake]

Really cool! So you are going to have an infinite number of maze configurations to explore in VR?

[idle osprey]

The game is simple. You're a rat (figuratively). Find the cheese in the maze to win. I'll add a timer. Eventually multi-level and multi-player so you compete against other "rats".

I'm just finding it hard to get a block of time to work on it since I recently changed jobs and have a learning curve there. I'm doing Golang for the first time and parquet files.

[sonic lake]

That's a VR rendition of the "rat race" I guess

[idle osprey]

Yep. Pretty much! 😉

[sonic lake]

LOL! Never looked into Golang so far.

I stick to Python.

[idle osprey]

It's...different. Yeah, I'm much more comfortable in Python.

[sonic lake]

Oh it has curly braces. Good. 🙂

[idle osprey]

I'm doing a lot of stuff there, too. Mostly with pandas, pyarrow and AWS

So very NOT vr related. 😦

[sonic lake]

Nope, but fun! Same here. Working a lot on NLP lately.

And wondering about the next VR tutorials.

Any suggestion?

[idle osprey]

I've a few ideas. One I'd really like to see is how to switch from a 3rd person character to a vr character and back. Either at runtime or on startup. I know that has to be in the GameState or GameMode, but when I tried to do it with Multiplayer, I could only get it to choose one controller or the other at startup and only the Host worked. The selection was ignored by the clients.

[sonic lake]

The switch I can definitely cover. VR multiplayer from scratch would be a challenge though. Unless I make it super basic.

[idle osprey]

Kind of an advanced topic, tho. VR Multiplayer would be interesting. UMG interaction in VR.

[sonic lake]

UMG I can definitely do.

[idle osprey]

Just the switch would be great. Multiplayer isn't easy, by itself.

A tutorial on UMG showing how to save Player Preferences. Like selecting smooth or snap turning.

[sonic lake]

It is relatively easy to bring two VR players into the same environment and have them wave at each other. But direct interaction and co-interaction requires a lot of extra custom code.

Player Preferences yes, that is also pretty straightforward. Not VR specific though, but it can be adapted.

[idle osprey]

Yes, I've been learning about it...and ownership. Network relevance. Events that need to be replicated and ones that don't. LIke, does the guy outside need to hear the door open from someone inside opening it? No...but they need to know the door is open and not closed when they get near enough to it to matter.

Physical hands would be interesting, too...so your hands/controllers don't pass through walls or drawers. Let's say you have a book in a locked drawer. You shouldn't be able to reach into the desk and just pull the book out. The drawer has to be opened.

[sonic lake]

Surprisingly enough the best explanations about multiplayer (networking) in Unreal are those from the Unreal Tournament documentation. And the original write-ups by Tim Sweeney himself.

Yes, realistic physics in VR has become mainstream after Half Life Alyx

[idle osprey]

A holster. How to attach inventory items to your body and grab them to use them again. Like a flashlight on your belt you can remove and use...leave behind...pick up again, and re-attach to your belt.

[sonic lake]

It has a couple of challenges also thanks to some long standing bugs with the physics

Yep, holster and equipping is also something I got requests for

Thank you for your suggestions!

[idle osprey]

I'll be looking forward to my next YouTube ping that you've posted a new video. 🙂

[sonic lake]

I still owe my audience a follow-up to the climbing tutorial

How to launch yourself and grab while falling

[idle osprey]

oo, yeah, I would like to see that, too!

[sonic lake]

It is also not that difficult, just combining vectors, but I have had a hard time explaining it in writing

Better to show it

[idle osprey]

Diagrams are good. Have a good day! Nearly 1am here, so I'm signing out.

[sonic lake]

Yep, good night, sleep well!

[brave trellis]

Dear Colleagues!
If it's not difficult, please tell me how to adjust the position of the camera in VR in such a way that while playing while sitting, you can move around the stage as if you were playing while standing? If someone knows, please do not consider it a great work, enlighten me! Thank you very much in advance for your help!

[sonic lake]

@brave trellissimply you take the VROrigin the VR Camera and the Motion Controllers are parented to and you give it a positive relative offset along the Z axis.

That will make the player feel higher above the floor.

[brave trellis]

Dear Marco!
Many thanks for your help! It worked really well. I am very grateful for your responsiveness! I respectfully shake your hand.

[real needle]

I guess this goes here, im having trouble getting a VR character to work right, it looks fine at start but when i spawn into the map from player start, im a lot taller than what its supposed to be, idk how to get the actor to spawn the right height and all. ive also tried having a cube where the camera is parented to and that spawns the cam in the correct position but the hands are way above the camera still, which is assume only the cam component moved and not the capsule.

anyone know why this is happening?

[pulsar roost]

@sonic lake Hello Marco! Thank you so much for your help 🙂 as Corysia said I’d like to walk while editing. You mentioned it would be with the old editor or build a custom experience. Would you mind to share some resources to check on?

[sonic lake]

@real needlecan you show the hierarchy of your character?

@pulsar roosthi Marissa. What you are asking is typical of ArchViz aka Architectural Visualization. In ArchViz you would typically create the environment and then let use walk inside it, placing or moving furniture, changing the colors of the floor/walls etc. Is that what you are after?

[real needle]

every time i hit play the camera goes above and ahead of player start for some reason

[sonic lake]

@real needlebecuase it has the wrong setup. You may want to take a look at my tut here: https://www.youtube.com/watch?v=EtEYIh9ndkc

See how the character is structured in it.

[real needle]

ima try and see what happens brb

[real needle]

that doesnt work

if i attach it to the origin and move the origin to the spot where the head should be then itll be in place where it needs to be, but then u cant freely move your head like to peak around corners, it moves the map with it

[pulsar roost]

Yes… as long as I am in the VRMode. No runtime at all 😅

Right now It seems that by modifying the VRScoutingInspectors template may work.

I somehow could make it by modifying the position if there is a floor under our inspectors. I was wondering if there is another way to do so. 😊

[sonic lake]

@pulsar roostif you want to use the Editor in VR that is the only way. Unless you use something like Virtual Desktop, but then you are in VR editing a 2D screen.

@real needleif you want that kind of behavior then you need a different approach. I'll give you some general pointers. You always need a Scene Component, which is usually named VR Origin, in between your pawn/character's root and your Motion Controllers and VR Camera components. This is the standard setup.

If you need more advanced features like having a body which follows you as you move in real life and graceful handling of collisions, then there is much more to code. In this case you may consider using the VR Expansion Plugin or some other VR frameworks which implement these advanced functionalities for you.

You may also consider taking the free course Getting Started in VR with Unreal Engine on learn.unrealengine.com

[real needle]

i got it to work, i guess there was something wrong in my other character i tried to make, only issue now is i cant rotate, trying to figure that out now

[sonic lake]

@real needlekeep in mind that if you walk "out" of your VR character and then rotate it, you are going to orbit around it. You need to implement room-scale rotation.

[real needle]

ok ill figure that out, i got it working

[sonic lake]

Cool

[real needle]

my issue now is this, when i move my head and look around, it kinda pulls a bit at the world. if that makes sense. i can move my head freely but the whole world and map kinda move in that direction with me

the whole map doesnt stick to the head, but when i look to the left i def see the world around me move a bit towards that direction.idk if that makes sense

[sonic lake]

did you change the hierarchy or what?

I think your character is being pushed back by collisions

[sonic lake]

can you make sure that the static meshes attached to your motion controllers are set to NoCollision

[real needle]

they were, but the flashlight i was spawning into my right hand had collision and the mesh component in the pawn also had some as well

once i set all those to non it worked better

[sonic lake]

👍

[real needle]

thank you, that was annoying, now to handle all other things XD

[pulsar roost]

I see I see. I was thinking right then hahaha ooof. Thank you so much Marco! I really appreciate it 😄

[gritty basin]

Hey there everyone! Hope all are well. I've been running into an issue with quite heavy aliasing in a media texture when deploying to Quest 2 using codec h264. In the editor I don't see any aliasing, but when deploying to Quest, there's significant aliasing and jumping of pixels. Have tried a variety of things, and set Full Precision highp for the shader, but still this issue.

If anyone has experienced this, or has any tips on how to get around it I would be super appreciative!!

[sturdy coral]

if it is undersampling you can manually add extra samples into the material. make sure to test in editor at same resolution as hmd and beware of the foveated stuff that might run on device and cause more undersampling in periphery

to be sure that is it test with a lower res video

[gritty basin]

Thanks for the response! Should I just disable FFR entirely? I had done that already but was still experiencing the issue

Might you have any resources that show how to add extra samples?

[sturdy coral]

instead of a texture sample node with texture in place, you hook one texture object node to two or more samplers, and adjust uvs to half texel offset, or something more intricate to avoid blur when not undersampling

I would confirm with a lower res video first because it might be something different

generally you should be able to have a video sized up to 2x per dimension of your eye buffer (not panel res) and will start reading down beyond that

that is if it is filling full view

[gritty basin]

Ah, I see

I think that might be where it's going funny. When I resized my plane to larger, it seemed the aliasing started to disappear

[sturdy coral]

you could also bake mips into your video somehow and change the uvs to a different mip based on ddx ddy calculation

[gritty basin]

But was obviously too big. The lower res might just do it

I see. Luckily the video is viewed from a static place, so if I get the resolution right it should hopefully just work?

[sturdy coral]

yeah, it should

the ffr regions will have more aliasing as if eyebuffer is at an even lower res there

[gritty basin]

Yeah, that makes total sense hey

As I was turning my head the aliasing would become .ore aoparent

*more apparent

What's strange is that I had disabled FFR and it was still there

Maybe after changing to the lower res video it will work out though

Forgive me, but what is the eye buffer vs panel res?

[sturdy coral]

eye buffer is what game renders to, which can be higher or lower than the screen

it gets scaled and warped into place for the lenses before finally making it to the screen, but they should be themselves adjusting how they sample if your eye buffer is too big, so that part usually isn't a source of aliasing

[gritty basin]

Ah, I see! So plane res is prior to warping?

I guess for quest eye buffer would be 1832x1920?

[real needle]

having a vr issue, i have room scale movement and rotation set up, but now i need the main capsule thats inherrited from the character base to not collide with anything, i need a different capsule that follows me to keep me from falling through the floor. but i also need it to constantly follow the camera, which obviously causes issues. how can i fix this?

[idle osprey]

What would be the c++ equivalent to the bp node Print string?

[sturdy coral]

@gritty basin no, that's just the screen res per eye. eye buffer res is what your game draws to before sending to the compositor

it depends on r.pixeldensity and other stuff, I'm not sure what all on quest

in steamvr you can find it what it will be at pixel density 1.0 by looking in the steamvr settings ui, not sure on quest. it may log it too

[idle osprey]

I'm trying to convert this bit of my blueprint code to C++ and I can't get it to rotate. If I put my rotation value (15.0f) in to the roll, the character spins. If I put it in to the pitch, the character will look straight up. But when I put it in to Yaw, nothing happens. The entire blueprint block is here: https://cdn.discordapp.com/attachments/744990258655133816/892638930233614336/unknown.png. And my C++ code is simply: c++ void AVRCharacter::SnapTurn(float Scalar) { if (FMath::Abs(Scalar) > TurnDeadzone) { if (Scalar > 0) { UE_LOG(LogTemp, Warning, TEXT("Snap Turn Positive %f"), SnapTurnAngle); SetActorRotation(GetActorRotation().Add(0.0f, SnapTurnAngle, 0.0f)); } else { UE_LOG(LogTemp, Warning, TEXT("Snap Turn Negative")); SetActorRotation(GetActorRotation().Add(0, SnapTurnAngle * -1.0f, 0)); } } } My log lines are printing as I expect: LogTemp: Warning: Snap Turn Positive 15.000000 But my character isn't turning like it does with the blueprint code.

Whoops, I pasted the wrong Set Actor Rotation node from the larger BP, but you should be able to get the idea. They're essentially the same.

[sturdy coral]

@idle osprey where do you call snap turn?

[sonic lake]

Also make sure your character isn’t set to follow the controller’s rotation

[sturdy coral]

yeah, main thing to watch out for is use 'controller rotation yaw' (controller there is referring to AController/APlayerController), and also just the order of events around that (because of FPS origins of the engine they do a weird thing where they apply all input rotations prior to other movement in APlayerController::PlayerTick in a somewhat weird way if you aren't making an FPS or need to rotate around a point other than the capsule)

[somber marsh]

helloo, can you publish VR games on the Epic store?

even if your game uses steam VR to run?

[real needle]

can i get some help witha vr issue? i dont know how to fix it

having a vr issue, i have room scale movement and rotation set up, but now i need the main capsule thats inherrited from the character base to not collide with anything, i need a different capsule that follows me to keep me from falling through the floor. but i also need it to constantly follow the camera, which obviously causes issues. how can i fix this?

[summer geode]

@real needle a new collision object channel called Floor set to block the pawn capsule?

[real needle]

that wont work, i need the capsule to follow the player, with room scale movement, you could be away from initial spawn point in 3d space, so if you wanted to go up stairs for instance, the capsule wont be with the camera to do that. itll still be at spawn

[summer geode]

why aren't you making the capsule set to be blocked only by "Floor" collision follow the camera?

[real needle]

your not understanding what im saying. i need the capsule to follow the character

i need to attach the camera to the capsule to keep from falling out of the map, but i also need the capsule to follow the cameras movements to move the capsule with the camera.

[sonic lake]

Not easy to help you out without seeing exactly what you are after. You should be able to set the root capsule of your character to query only and set its collisions so it is not blocked by any world actor.

You can also move the character to match the position of the VR camera (horizontal plane) and then offset the VR Origin by the opposite amount so everything stays in sync.

[real needle]

idk how to do this,

that sounds like itd help but im not sure how to do this.

[sonic lake]

I am on my phone so i cannot show it to you, but basically if the camera moves from A to B and you want the root capsule to also be in B, you need to move your character to B. But since the camera is parented to the VROrigin which is parented to the root, when you move the character the camera also shifts. To bring back the camera to B you need to move the VR Origin back to A.

If you draw it it will become apparent to you.

[real needle]

i kinda understand what u mean, but idk how the code would go. i understand ur busy, but i was in special ed lol def need a little extra help with learning it

basically id need to see a bp to understand it better

[sonic lake]

We worked out the same thing with @idle osprey maybe she can help you

[idle osprey]

I can point you to a good VR movement tutorial

[sonic lake]

Oh there she is!

[real needle]

that would be lovely.

[idle osprey]

I'm on the phone with my mom ATM. Once I get off, I can show you.

[real needle]

ok dope. until then ima try some coding i found

see if it works

[idle osprey]

Where should I check that?

[sonic lake]

Character and Character Movement Component

Use Controller Rotation Yaw iirc

[idle osprey]

Someone else recommended that, too. I'll give it a try.

[summer geode]

Of course it works 💯

[idle osprey]

What I saw last was it got set from 0 to 15, but next frame it was back to zero.

[sonic lake]

It’s reapplying the controller rotation which is stuck onto 0

[idle osprey]

void AVRCharacter::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent)
{
    Super::SetupPlayerInputComponent(PlayerInputComponent);
    InputComponent->BindAxis("Turn", this, &AVRCharacter::SnapTurn);
}``` This is my WASD hook for SnapTurn.  A comes in as -1 and D comes in as 1.

@sonic lake @sturdy coral Looks like AddControllerYawInput(SnapTurnAngle); is the fix.

Thanks!

[sturdy coral]

I'm not sure why the BP version worked, unless it wasn't set to follow controller yaw

[idle osprey]

I still don't know where that setting would be.

[radiant garden]

UseControllRotationYaw is on the Pawn/Character under the "Pawn" category

[idle osprey]

I definitely didn't change that in the BP solution.

[radiant garden]

There is also an OrientRotationToMovement bool on the CharacterMovement component

[idle osprey]

Yeah, I didn't set any of those.

[idle osprey]

What is considered realistic values for crawling, crouching, walking, running, and sprinting? I'm putting in 50, 200, 300, 600, and 800 as guesses, but I was wondering if there's any sort of standard used for movement speed?

[uneven sonnet]

Hey, do you know how to force display the Steam VR controller binding section via UE4? Normally you would open Steam VR, go to controller section, show controller bindings

[sturdy coral]

@idle osprey you can look up human values, but 2d games usually go a lot faster. It's in cm/s. VR you may want to go even slower if you are doing smooth loco

you can also measure your animation, distance from footplant to footplant, to reduce sliding, if you aren't already doing some kind of IK speed scaling

[idle osprey]

I was thinking of doing the math to figure out cm/s for the average human walk speed of 4mph. But I thought I'd ask. No, I'm not doing any IK yet. Going to be, but not that far along yet.

[sturdy coral]

just put it in google like "4mph in cm/s" and it will convert, sometimes it gets tripped up and you have to reword the units, or try wolfram alpha

[idle osprey]

wow, wolfram alpha is cool

179cm/s btw

[ashen vector]

how can I setup the engine to render this way?

[sturdy coral]

learn tab stylized rendering example project

[ashen vector]

thanks.. I meant the side by side to be able to display diferent images on each eye.. do yo know if that projects does that?

[sturdy coral]

@ashen vector vr does different images per eye by default

you can change mirror mode to make the mirror display it similarly

[ashen vector]

I am following this information https://www.youtube.com/watch?v=VfuQv_5RDRA I wan to display a stereoscopic 360 image, but I have an issue at where just a stripe at the center on the HMD is on stereo, everything else is mono.. not sure what is happening.

If I close one eye I see the screen is split in the middle, same for the other eye, I suppose it should be displaying a full image for each eye instead..

[sturdy coral]

it depends on many things like instanced stereo, but you can do it all from a custom node and looking into view uniforms parameter or something like that

View.StereoPassIndex

[ashen vector]

mmm no idea what I am doing sorry.

Instanced stereo didn't work since it renders the same thing on both eyes or thats how it felt.

the problem I see is the engine is rendering both images (left-right) on both eyes at the same time, and spliting both eyes in half instead of showin the left image on one eye and the right image on the other eye..

[ashen vector]

HMD mirror mode is not recognized on v4.27 I think

Left eye should be yellow, and right eye should be purple.. any ideas what is wrong with this?

[sonic lake]

A very fast walking speed for a human is 5 km/h which converts to 1.38 m/s hence 138 cm/s. 179 cm/s is more (slow) running.

An average walking speed which most people tolerate in VR is 1 m/s or 100 cm/s.

[kind palm]

I have a question, could unreal engine handle switching between VR and PC in application during runtime?

[sonic lake]

@kind palmyes. Just disable the stereo mode on the HMD and it will revert to 2D/PC.

[somber marsh]

how do you package a project for oculus rift? is it android astc?

or windows?

[wheat holly]

The Rift is a regular PCVR headset it doesn't use android, that's the Quest that uses that. Windows is I believe the most common used platform for the Rift (I'm not even sure if Oculus supports Linux and perhaps even Mac?).

[idle osprey]

Rift would just be a windows app.

[idle osprey]

Seated VR. Would that be Eye tracking instead of Floor tracking? My next challenge is to get my movement code working for someone in a seated position. I'm thinking about people who are perhaps handicapped or bedridden or for some other reason unable to stand and crouch physically. This means I'll have to implement crouching and crawling via button presses rather than just tracking the height of the headset. I know UE has a Crouch() and Uncrouch() call. I need to figure out how to use those in VR.

[void parrot]

Anyone know why SteamVR can spawn you at a negative value height wise?
Having real trouble with this and its working fine on Oculus, its just SteamVR refusing to play along

[sturdy coral]

Oculus defaults to eye level, everything else floor level

There is a node to change it, tracking origin

[void parrot]

Yeah its set to floor level for both devices and works fine on Oculus
Reset Orientation and Position might be doing something to it as well

[idle osprey]

Are you sure about that? Rift did, but not sure any other Oculus does today.

[sturdy coral]

maybe not quest, I haven't done any dev for that

[unreal pelican]

Hey I was wondering if anyone here has experience with WMR, windows mixed reality. I am using a samsung odyssey, and I am having issues with basic locomotion via thumbsticks. I've got the WMR plugin and steamvr plugin.... not quite sure what the issue is. Any advice is greatly appreciated!

[idle osprey]

@sturdy coralkinda goes back to my question above....is Eye level for seated vr? Definitely floor is for room-scale

[sturdy coral]

@idle osprey yeah, eye is primarily for seated, main thing is they can recalibrate seated position through system menu

[idle osprey]

I'm not sure what to do with the capsule...or the camera, I guess. With roomscale and floor tracking, I put the VR Origin at -88, so it's at the bottom of the capsule. I'm thinking that's probably not right for seated.

My whole camera height and crouch detecting goes wonky if I go to eye level tracking, so I have to figure out what's happening.

[sturdy coral]

@idle osprey for now I have everything at floor origin. what I do on start is:

prompt for standing/seated preference.

if standing: prompt to stand still for height calibration (just for scaling avatar)

if seated:
-prompt to enter real standing height.
-prompt to calibrate seated position.
-Then based on entered height, raise up the origin by enough to make seated height == entered height

for all that I have some estimate of eyes are Xcm below top of head/height

[idle osprey]

yes, I chose 10cm for that.

[sturdy coral]

I will probably switch to eye origin for seated at some point instead, recalibrating eye origin I think has had bugs in some runtimes in the past

[idle osprey]

I don't have a UI yet. So far I'm just setting bp exposed variables in my VRCharacter header that I'll hook up to UMG eventually.

I'm going to have to figure out height calibration, too. So far, it's been working fine for me, but...I know I'll get bit eventually.

[celest swan]

anyone know a good tutorial or way to make a Physical UI for VR?

[sonic lake]

@celest swanlike in pressing buttons etc.?

https://www.youtube.com/watch?v=l9hjb7kt854

[celest swan]

as in i have a tablet that i would like to hold with physics and stuff and also reacts to button presses

[celest swan]

okay it works

its kinda janky but it does the job haha

[sonic lake]

@celest swannice

I don't have a tutorial on that specific subject, but glad to hear you are getting there

[steady shoal]

hmm... decals are still not properly supported in ue4 mobile/vr ?

[dreamy ivy]

no, there pretty expensive. But a good trick. If its on a specific surface and wont need to wrap, just put an image on a plane and then place it into the world. If its blood splatter and stuff then its way more difficult.

[limpid widget]

Did anyone ever get this crash when running a vulkan build for quest 2?

Any good Fake Glow tutorial for forward rendering? (I mean glow effect whithout hdr on)

[jovial hamlet]

Haven't seen any tutorials, but one way to fake bloom is to put a camera-facing sprite near the object that you want bloom for. I'd imagine it requires a lot of tweaking and doesn't work for everything.

Also, we've made a lightweight (11 instructions) tonemapper that handles high emission values the same way as the default filmic tonemapper, but without HDR. Might be useful if your emissive materials become oversaturated with LDR.

[jovial hamlet]

looks like this (the spheres have different emission values)
https://gist.github.com/da-molchanov/85b95ab3f20fa4eb5624f9b3b959a0ee

[hard relic]

Thank you for your answer. I need glow over every luminescent things in my game. Every bullets, enemies, etc…
We are agree that your « facing camera trick » will not help for this case?

[jovial hamlet]

I think it might look good for small things like bullets, small distant lights, or for quick explosions. As for the enemies, I guess the glow can be baked into the textures, but its is not true bloom of course and will look flat. I don't think there is a good general solution that works in LDR.

How to make Unreal editor VR mode to work on hololens 2?

[hallow knoll]

That's not supported

[dire juniper]

Thanks @hallow knoll for the webinar 👌

[novel hollow]

Does Unreal support Simultaneous Front and Rear camera tracking.

[hallow knoll]

Eyyy you're welcome! (and for those who missed it, the VOD will be available within a day or two)

[hallow knoll]

Does ARCore or ARKit support that?

Seems like ARKit does, but not ARCore

[novel hollow]

Yes, you are right. ARKit does

[hallow knoll]

AFAIK we don't have explicit support for that, but theoretically you should be able to

[novel hollow]

Thanks, I was going through Unity ARFoundation Forum, in Unity there is some flag that needs to be switched to enable Face tracking while using Rear AR Session. Anything in Unreal that could help?

[trail shale]

How do I ensure that when I load a level, the Steam VR icon DOES popup (basically block on load) - I'm getting hitches in the level and without messing with project streaming settings, it would be easier to just shift to a loading screen (even the native Steam VR is fine) so that when it is done, the experience is smoothed out - is it just a matter of using "Block on Load" or is there another setting I can do as well
**
Basically looking for a "Keep Player in Steam VR environment until this is all loaded and running normal"**

[hallow knoll]

The startup engineer in me would say "execute something that keeps the game thread just barely chugging along" 😅

Level streaming improvements for VR is something I've added to the long QOL-list, but it's apparently not low-hanging fruit. I opted in to not use level streaming to get around it.

[gentle timber]

@radiant garden I noticed your posts about the android views looking different to the Shader Model 5 views and was having similar problems - was wondering how you dealt with it in the end?
I happened to see this old post in the forums - https://answers.unrealengine.com/questions/117405/view.html
and find that when I gamma correct a screenshot of the Shader Model 5 view to 2.2 I am pretty close to what the android view provides.. Bit confused as to which is incorrect, or needing the correction!

[radiant garden]

Ultimately I was being a bit of a noob. I didn't realize unreal engine's rendering engine uses sRGB. The pow 2.2 fix helped me realize I needed to check the sRGB box when importing my textures.

I no longer do pow 2.2 in my material

[gentle timber]

hmm so in my case, what am I experiencing?

that's the android view on the left & the shader-5 on the right

it's mostly random megascans stuff & the textures have all got srgb checked

or is this actually all correct...?

[tired tree]

@trail shale in steamvr there is an API call to force keeping the overlay active

specifically to allow for application loading

nothing native in engine currently runs it, but its a minor function call to turn it on/off in c++

[hard relic]

Aahr i just understand what you are saying.... it is already what i'm doing... And i have to deal with dithered transparency because of sprite are rendered in front of every mesh. never behind. So the result is... well.. dithered.

[radiant garden]

I'm not sure. I haven't used megascan assets.

[trail shale]

Well crap - that's at least good to know so I don't go spin my wheels, if someone like you can't get it to work smoothly, well, I'd probably better do likewise - I couldn't find much on the project streaming settings, things like "components registration granularity" but find specific explanations on how changing it to this number will do this

[lean yoke]

Hi lads, pretty much new with UE development and VR development. I got this semester long school project and what I plan to make is like a very primitive in-game map editor in VR. Kinda like UE's VR editor but more simplistic.

What I want to figure out is how to have the player place an asset (or prop) by pointing at a spot on the floor, pressing trigger, and it spawns.

[chilly ocean]

How do I improve text quality in VR? Currently, the text kind of jitters and shakes when I feel like that shouldn't really be happening

Specifically in my game using Unreal Engine

[real needle]

Is hololens MRTK works on unreal 5?

[real needle]

Does VR unreal editor mode works with Hololens 2 streaming? What would it take to make it work if not?

[brave trellis]

Hello guys, dear colleagues!
I have one big question. How and where can you place a finished VR game? I have developed a small VR game. I want to publish it, for example, in the Epic Market and on the Oculus Market, so that everyone can download it for FREE and install and play for themselves. I don't want to make money on this, I just want people to be able to get it for free, whoever needs it ...

If someone can help me? Please write to me personally. Thank you very much in advance and shake your hands!

[agile marsh]

what is the best PC spec for oculus quest

[agile marsh]

HP 15 Core i5 8th Gen - (8 GB/1 TB HDD/DOS/2 GB Graphics) 15-da0077tx Laptop (15.6 inch, Sparkling Black, 1.77 kg) will i be able to develop using this laptop

[sonic lake]

It depends on which kind of VR you intend to develop for (PC or mobile) and which VR headset you are going to use.

Since most mobile (stand-alone) VR devices can work in tethered mode, which makes it faster to develop with them, if your budget allows you should go for a VR-ready laptop.

If you don’t care about that and just want to develop for mobile VR, plus you have budget constraints, any laptop that has a USB-C 3 port and meets the Unreal Engine specs will work.

Before buying anything check online what people are reporting and if anyone is using it with VR.

[agile marsh]

my laptop has usb 3.0 and I am arable to develop games other than VR , I only have budget for a HMD right now ,I have checked in few websites but was not able to find the exact spec required for oculus quest

before I invest in HMD I want to know if I will be able to develop with the laptop that I have right now

[sonic lake]

With those specs you should be able to develop for mobile VR by launching directly to the device.

If you get a Quest 2 for example, Oculus Link won’t work but you can launch your VR experience directly on the device and run it there.

[agile marsh]

what HMD is the best for me then?

[sonic lake]

You are limited to standalone VR devices. I am familiar with the Oculus Quest 1/2 and the Pico Neo 2/3. There could be other options.

[agile marsh]

thank you very much

[sonic lake]

Check anyway if others are using the device you want to buy with a PC similar to yours, just to make sure it works (it should though).

You are welcome

[worthy quest]

Hey guys, does anyone have some experience with the mixed reality capture framework and would be up to answer a few questions? Using the calibration tool results in a lot of pain and the results are pretty bad.

[marble lantern]

Hello everybody 🙂 does anyone here who tried the vr 4.27 template with an htc vive 1? The haptic feedback is actually buggy, my Vive controllers in every grab and trigger event starts vibrating a lot and for a long time not following the input duration! In some cases I had to turn off the controller to stop it. Has anyone here experienced something similar?

[fiery cloud]

As far as I know, haptic seems broke in UE4 for a long time for vive wands. Force feedback seems to still work. I will take a look and see if I can find an issue

Specifically, broke in UE4 for vive wands.

[raven dome]

idk if anyone will know this but if i wanted to get somthing similar to the onward body physics with like crawling, turning crouching (1.7) on a custom character in my own unity project is that somthing that was brought from the assets store or was it privately coded by dpi

[urban ruin]

hi guys, what file format should i export for testing in HTC VIVE and Oculus Rift S ?

[sonic lake]

@urban ruinyou need a format which can be run on the host machine, usually you would package to an EXE

[urban ruin]

hmm i have never done that b4

right now my problem is oculus = export in android ; how abt htc vive= ?

[lucid forge]

Hey, does anyone know how to get Enhanced Input to recognize HP Mixed Reality inputs?

[sonic lake]

@urban ruinYou mentioned the Rift S, which is a PC based VR system. The experience runs on the PC and the HMD is just acting as sensor/display unit. The Oculus Quest/Quest 2 on the other hand is a standalone VR system, but can also work as PC based VR through Oculus Link. If you intend to use it as standalone VR system you Launch (a kind of install) the VR experience to it, after which you can disconnect it from your computer and play it standalone.

[urban ruin]

oh wow nvr know abt it, thx marco

[sonic lake]

You are welcome.

[hallow knoll]

It’s not really supported anymore, I suggest you use a third party tool like LIV

[hallow knoll]

There are no haptic events on trigger pull in the VR template 🤔 I have experienced “poor” haptic effects but that’s only on my vive pre controllers that are as old as the vive

[hallow knoll]

Have you enabled the HP controller plugin? That said I don’t know if enhanced input works with motion controllers, it probably will in the future though

[twin heart]

HI anyone know how to set for the VALVE INDEX Fingertracking? Woud be great to get an advice

oh hi @hallow knoll was before misvnthrope. Didnt know youre here.

[marble lantern]

There is trigger tactile feedback in the interaction with the gun when firing 🙂 Do you think that is a htc vive 1 controller issue only?

[marble lantern]

with previous version of vr template I never had this type of problem,it's the first time. What do you mean to "force feedback"? It works... but too much and too long. 😩 anyway thanks for help 🙂
Edit: I discovered the ForceFeedback node that you intended, thanks 🙂

[weak dirge]

does anyone know how to get body movement on charachter in unreal engine without a body suit

[trail shale]

ugh, if you are a masochist and like suffering, you could manually do it with motion controllers strapped to parts of you body (or the vive trackers) - you'd have to break it up though, you wouldn't be able to do it all at once (probably) even if you had that many tracker/controllers

[spark stag]

Anyone have experience getting a usable AndroidManifest.xml that Oculus dev hub will accept?

[fierce oriole]

Hello world! Unreal newbie here.. The onboarding with the VR Template is awesome in 4.27.1 - love that I just plug in my Quest and I can preview on device without any hassle.

What’s less clear to me is how to actually deploy to the device? The OpenXR docs in the manual don’t cover it. Should I still follow the Oculus VR plugin pathway instead?

Much I’ve found online still seems to detail manually installing Android Studio or SDK. I’ve been through a similar process in Unity..

[sonic lake]

@fierce oriolefrom Unreal, with your Quest connected and set to development mode, you Launch to the device instead that Play in VR. That triggers the packaging for Android/Quest, creates the APK and pushes it to the device.

For this to be possible Unreal needs to have access to the Android SDK/NDK. There are many guides around on how to set it up: https://developer.oculus.com/documentation/unreal/unreal-gsg-quest-quickstart/

[fierce oriole]

Ah ok, thanks. I’m just trying to locate the Android SDK/NDK as I must have it from my Unity install so then I can just point UE there

[fierce oriole]

Hmm, looks like I need to install Android Studio and follow the Unreal Android install guide :/

The batch file they provide to do the setup requires it

[frigid geode]

Hello everyone. I just upgraded to UE4.27.1, and it's broken my VR project, which was not using OpenXR. The development build crashes as it tries to enter the game, and the logs just stop - sometimes in the middle of a sentence, or otherwise with what appears to be the start of a stack trace. I'm not sure what to do to figure out what is going on, or what could have changed; I noticed that they added a bunch of OpenXR plugins that could conflict with what I previously had set up, I tried disabling them, but it didn't seem to make a difference. I'm not sure how to debug if anyone has some ideas...

[clever iron]

Draw calls will be the death of me on Quest development T_T

[sonic lake]

Yes, especially if you have too many of them. 😉

[clever iron]

Make level -> reduce the hell out of level to eliminate as many draw calls as possible

Then realize the multiplayer game that should hold 32 players can only hold 9 cuz of draw calls

damn hardware

design decision, how important is it to see someone else's hands in multiplayer? cuz that's two draw calls per pawn + network bandwidth

[sonic lake]

It depends on what those hands are for

@clever ironalways found this inspirational: https://80.lv/articles/optimizing-robo-recall-for-oculus-quest

[clever iron]

I use hand positions to cast skills, so it might look cool for that reason, and for coms. But not an essential gameplay feature so... I think it's gone

I'll have to watch it!

[clever iron]

lmao "when I first started doing this I felt like I needed a support group, you see those 100ms spikes and you're like there's no way I can do thissss"

Truth

[sonic lake]

Right. But eventually they released it. That's part of the reason why I find it inspirational.

[clever iron]

Does anyone have advice for using rederdoc with Vulkan? I can't seem to get it to show frame by frame draw since vulkan pools it all and then draws at once (as far as I've read)

[wheat holly]

Wait, that game is on Quest? I would imagine the graphics have gotten a big downgrade on it, but that’s a good job they have done there xD

[sonic lake]

Yep. I have played both the PC VR version and the Quest version. They have done a great job with that port.

[clever iron]

"(paraphrasing) When talking to the artist it was can we make this material additive? Or else it's gonna be deleted, your choice"
There's a ton of optimization that went into it, very useful video

[wheat holly]

I’m watching it now yeah, I’m surprised they also had so much issues with blueprints. According to them converting it to C++ with nativization saved them on average 2ms up to sometimes more 😅

[clever iron]

that virtualization layer can be big for something as limited as mobile, I need to lookup the auto nativization function and do that too lmao

[sonic lake]

Last time we benchmarked it blueprint nativization led to a performance very close to native C++, just 5-10% slower.

[wheat holly]

Just finished the video, they did a really good job explaining the topics. Some things go a bit beyond me, but they still shared a fair amount of good ideas. These are the things we should have pinned in here honestly 👀

[wheat holly]

I mean, that’s probably a still a lot better than before right? Even though it's a little slower than manual written code.

[sonic lake]

You mean respect to the Blueprint VM? Definitely.

[clever iron]

Yea I can't figure out a good way around it, goodbye hands, goodbye healthbars that are always visible, hello single material character mesh and party based visibility on character names. 6 minimum draws down to 1 minimum, 4 max

Optimization is so much fun

[charred blaze]

Hello, I have this issue where when I enter the VR preview mode, the location of the headset within the VR world is very far up in the sky, away from the world origin, any idea what it is caused by or how I can fix it?

Oh, disregard, I had the "current camera location" checkbox checked :D

[lofty iris]

@charred blaze if you use set tracking origin floor level, you need to spawn the player with the bottom of the capsule at Z zero that´s the floor level and then teleport the player to the position you want him to be.

[quick kiln]

Hello, I'm using OpenXR with Oculus Quest 2, and I've some weird issue with it. On the input mapping, when I chose Oculus Touch (L) X Press to detect that the button X on the left controller is being pressed, any input is detected anymore. In other word, I can press/touch/trigger/grip so any input is being received / captured by the game.
When I remove Oculus Touch (L) X Press from the Input mapping, everything work as usual.
Note: I tried to remove any other input mapping, thinking that it was conflicting, but it didn't solve the issue

Do you have any idea??

[quick kiln]

Btw, This issue happens only with the `X press'. If I set any other button it works just fine.

[sonic lake]

@quick kiln apparently it has been reported before: https://forums.oculusvr.com/t5/Unreal-Development/Quest2-Key-Binding-Issues-4-27-1-Binding-X-Key-breaks-all-input/td-p/889857

[quick kiln]

@sonic lake Yup, I saw it and replied too. I wonder if that forum is active. Do you have an idea if the oculus OpenXR plugin source is available?

[sonic lake]

@quick kilnthe engine ships with the client side of OpenXR, the specific device implementation is part of the Oculus software stack and I don't think they share the source code for it.

[quick kiln]

@sonic lake Ok thanks!

[fierce oriole]

Hmm, still not quite there it seems. First I had to edit my Android install to look for a dx.bat and associated jar file rather than the provided d8.bat. With that in place I now get this. I'm just attempting to deploy the 4.27.1 VR Template to my Quest 1:

@real needle How did you install the Android tooling?

[real needle]

I used version 3.5

before that I tried 4.0 and 2020

I clicked the android setup bat as well

Also started a new blank unity project just incase

[fierce oriole]

I just successfully deployed the 4.27.1 VR Template to my Quest 1

I used Android Studio 4

[real needle]

Do you need visual studio installed as well?

[fierce oriole]

no

[real needle]

some tutorials mention it and others dont

gotcha, taking a break, will try later on again, take care

[fierce oriole]

all I needed to do was this https://docs.unrealengine.com/4.27/en-US/SharingAndReleasing/Mobile/Android/Setup/AndroidStudio/

Thanks! I'll try it out this after noon

[rocky nexus]

on somewhat related note, how do i debug quest project on quest? im getting native crash when i load a level with not very helpful error. im using this guide https://docs.unrealengine.com/4.27/en-US/SharingAndReleasing/Mobile/Android/AndroidDebugging/ but it doesnt seem up to date. for one LLDB Startup Command file seems to be missing in 4.27, but perhaps it is no longer needed. worse the app fails to launch, crashes on startup without debugger being attached. signing is also different requiring reinstall, which might be the issue

[rocky nexus]

meh seems the issue was that i had 'for distribution' checked, which makes sense i guess, but its not mentioned in the guide :<

[fringe blaze]

How do I get the controllers to vibrate? I tried the async "Play Dynamic Force Feedback" node and it doesn't do anything.

I have a CV2 but I'm looking for a platform agnostic solution.

[rocky nexus]

im using Play haptic feedback in Playercontroller

LLDB stuff seems to be available in gh repo but not in distribution, nice.

[tired tree]

@sonic lake for the record on that input X button bug if you have to answer to anyone else i nthe future

epic has mentioned that they think it is a runtime issue on Oculus's side

as the openXR json appears correct

[dawn lark]

does Oculus Quest have its own RenderEngine?

Guys, this is a tough one. I need to get Nreal Light AR/MR headsets, and i need to know if its possible to compile .APK's for android phone and run them through the (phone) then the headsets. The goal is to either see markers and 3D models on the ground, or atleast to see AR models through the glasses
The problem is i dont know if the Nreal Glasses can run unknown apps or not. And im thinking of buying them. I was suggested to get the developer kit
but i wouldnt need the developer kit, if i got the normal consumer version of the headsets and if it accepts and runs .apk's compiled with ue4

... i figure if i compile a apk that would work on phone... it should work on glasses too

but this is a big guess that will cost me $500 or $1200 depending on the headset i need

please help

Anyone ?

... oh wonderful, i just found out Epic games sued Nreal for sounding too much like Unreal. ..

[real needle]

ok so i got a reply from Nreal community. ONE person said its possible. I hope im not making a mistake.

is there no return policy?

just return it if it won't let you deploy a build and there was no way to figure it out beforehand

Hey guys, anyone having trouble unlocking developer mode in the latest version of the Oculus Quest 2 app?

I can't find the same option that existed before they changed the setting menu.

[sonic lake]

@obsidian anchorit's on the first screen of the device settings once you connect to the device from the app

[obsidian anchor]

It's been removed from the the app, I've just found a video talking about it, I'll post it here if it works

[sonic lake]

Really? I still see it, but I have a Quest 1 not 2

Otherwise from the Oculus Dev Hub

[obsidian anchor]

Hm. I can't see a way to do it in ODH either, ODH still says "toggle on dev mode" without saying where.

[obsidian anchor]

Looks like it was that headset specifically with issues. Couldn't factory reset it without the app, then when I did I couldn't get it back to developer mode.

[sonic lake]

@obsidian anchorok so you can see the option on other Quest 2

[obsidian anchor]

I can't see the option on any actually, the other headset worked before I connected it to the internet

Nobody else seeing this issue?

[sonic lake]

Did they take it out with an update? I guess by mistake. Oculus does that from time to time, like when the blocked all Rifts worldwide with a bad update

[sturdy coral]

they turned on some verification requirement, not sure if related

https://twitter.com/ID_AA_Carmack/status/1452664427132510211

John Carmack (@ID_AA_Carmack)

For @RNKinsenquera and anyone else that recently had side loaded apps stop working on Quest, the issue is that this just started getting enforced (much later than announced): https://t.co/wjcTlZqVKr If you finish the verification process, "unknown sources" should come back.

Is it expected that 427 vr template runs at 20fps on quest 1? It seems to be using quest friendly settings, stat unit says the game takes most time…

[mortal fable]

Has anyone experienced lag or warping issues while running the
VR Template for Unreal 2.47 (PCVR)? I'm experiencing this on two separate computers (one running an GTX 1080 and another running a RTX 2070 Super). I've used both an HTC Vive 1 and Oculus Quest 2 (with a link cable).

[rocky nexus]

perhaps its for similar reason as the perf issues i encountered, but i didnt test on desktop

[primal sluice]

This is more of an UX question, but I did not find more appropriate channel. Are there any decent materials or advices on UX of player's movement in tactical VR game?

Seems like movement with controller's stick is troublesome, so I was wondering if there are good snap-point approaches where player could select a point to run towards (to next cover).

[tribal osprey]

You could probably just use a teleport system that snaps the trace to cover if it's available. The only thing is I'm not sure that kind of locomotion will go well with vr

Would be an interesting concept to try though

[tired tree]

pretty sure you would lose more players to a lack of smooth locomotion than gain from that type of setup

[idle osprey]

I think Wands is a teleport-type of game. Robo Recall is. Personally, I won't play them because I want smooth locomotion.

And troublesome in what way? Motion sickness? Hard to implement? Difficult to move and shoot?

[idle osprey]

I have a lot of trouble with the VR Template. When I use it, my FPS drop to 25 if I look down, even in an empty scene. Victor said Epic is aware of it. I decided not to use it and I'm getting great FPS having started from a blank project.

Has anyone any insight on how to toggle crouching in VR?

[sturdy coral]

just move vr root down, but if attached to capsule and crouching with character movement component, crouch shrinks the capsule too , so you only need to move half as much down (midpoint of capsule will lower by half of crouch amount when the capsule shrinks, you lower vrroot by the other needed half)

[idle osprey]

Hmm, that easy? I'm making this much harder than it needs to be, then.

And....my Mac reboots for a security update ...sigh

[primal sluice]

Dificult to move and shoot. Maybe it is a good idea to snap player’s zone when there is a combat encounters, but let him move with stick otherwise?

[sturdy coral]

there may be a bit more to it than that

also, I think it takes engine modifications or at least heavy character movement component subclass overriding if you want capsule to follow along with head, as the player phsyically crouches, rather than just a crouch button

[idle osprey]

Nope, solved that one with Marco's help earlier this year.

It's actually pretty easy.

[sturdy coral]

ah cool, I should clarify with rollback networking support though

mordentral's stuff probably solves that

[idle osprey]

I think you'd just have to replicate the capsule, but yes ..I haven't done networking yet

[sturdy coral]

it is stuff like when you replay a move from packet loss you have to redo the crouch state fractionally and stuff, otherwise if you were ducking when you went under something then standing, when it rewinds/replays you are standing then hit the edge and your client rubber bands. CMC already handles it for crouching as a boolean state but not gradations

[idle osprey]

I can see that would be problematic. I know the theory, and have done lots of networking, but haven't done replication in Unreal yet. That's coming, tho. Maybe next year.

Instances static meshes are my bugaboo today. Nearly have it, but not quite.

[wintry jewel]

Hey hey, I'm just trying to get the length and width of the play area currently on a Quest. Using OpenXR. Every time this runs, a value of 0 prints. Have I done something wrong? Thank you for reading 🙂

[sonic lake]

@wintry jewelhow are you using the Quest? Via Oculus Link or standalone?

[dreamy ivy]

Thank you, so glad the videos are being helpful.

[wintry jewel]

Link!

[sonic lake]

@wintry jewelfirst check, I am not getting any value either

[wintry jewel]

Am I doing it the right way? This was the only documentation I could find, so a bit puzzled! Thank you for testing anyway, really appreciate it 🙂

[sonic lake]

@wintry jewelI think it may be a problem on the Oculus side with the OpenXR implementation. Also not 100% sure 4.27.1 has the latest version of it.

[orchid adder]

Wow, so little focus on VR/AR, do you think Unreal is a good focus for it or should I stick to Unity for the time being?

[half reef]

Hi, what do I need to do before I can enable the VR editor mode, I can play in VR but the "VR mode" is greyed out

[tribal osprey]

What device are you on?

Index, Quest, Vive, etc

I believe if it's anything but an Index you just need to set the base software for that headset as your openXR runtime. Also, you'll probably want to pick up the Headset's specific OpenXR plugin. Quest has an Oculus OpenXR plugin which works better than the default one.

If it's an Index I believe there's some resources online for how to setup the SteamVR input, which I think you have to do alongside the openXR runtime stuff. Do not quote me on that though, I do not use an Index

[half reef]

oculus quest 2

its linked to desktop via link

[tribal osprey]

Nice, that's my setup too

Just open the Oculus software, go to Beta settings, and set it as your openxr runtime

Then go to Unreal Engine and pickup the Oculus OpenXR plugin

Once you've done that you should be able to use it

[half reef]

hmm just opened 4.23 instead of 4.27 and vr mode is available now

[tribal osprey]

Probably because it's not using OpenXR

[rocky nexus]

You can also use virtual desktop

[tribal osprey]

Does it work? I was having trouble setting it up

Do you have to set Steam as your openxr runtime?

[rocky nexus]

You need to open editor via streamer

[tribal osprey]

From the desktop right? Not on the Quest 2 app?

Because it doesn't show up as an option on the Quest 2 app

[rocky nexus]

Like this
Additional Notes
You can launch games that aren't part of your Oculus or Steam library by right-clicking the Streamer icon in the system tray, selecting "Launch Game..." and locating the executable. Alternatively, you can inject games through a batch file (.bat) by using: "C:\Program Files\Virtual Desktop Streamer\VirtualDesktop.Streamer.exe" "[ExecutablePath]"

[tribal osprey]

Yeah yeah alright

I remember seeing that on their updates page

[rocky nexus]

I do the bat, open project file

Doesnt work if you use editor to select, new window

[tribal osprey]

I'll give that a go when I get home, would be awesome to charge my headset while working

Thanks!

[dark nacelle]

Can anyone help me out? I'm following a tutorial using the VR template in UE5 but the code for room scale movement is causing my character to fly in the direction of the headset constantly. Here's the function in question. If I turn it off the problem goes away.

[tired tree]

@tribal osprey its not that the oculusXR plugin "works better" than the openXR module, the oculusXR module is fixing gaps in the openXR implementation from oculus, its not a reimplementation of the openXR module. You have to have both enabled

oculus is / has been lagging behind on openXR implementation api side

[sonic lake]

xrGetReferenceSpaceBoundsRect(Session, Space, &Bounds) seems to return 0,0 regardless

[hallow knoll]

Oculus Quest w. Link has a bug in the runtime where no data is returned. If you launch it on device, or use an Oculus Rift S the function works

[sonic lake]

I suspect it hooks up to nothing on the Oculus side of the API

Ah ok, thanks Victor

[hallow knoll]

And afaik "stage" is the only reference space that's been implemented in the specification

[hard relic]

Aarg... problem. Any idea why my video file is playing correctly on a mesh surface but become black when exported into the Quest? ...

[hallow knoll]

VR Editor Mode doesn't work with OpenXR yet, but the editor team is working on it

[sonic lake]

I tried all of them anyway

FVector2D FOpenXRHMD::GetPlayAreaBounds(EHMDTrackingOrigin::Type Origin) const
{
    XrReferenceSpaceType Space = XR_REFERENCE_SPACE_TYPE_STAGE;
    switch (Origin)
    {
    case EHMDTrackingOrigin::Eye:
        Space = XR_REFERENCE_SPACE_TYPE_VIEW;
        break;
    case EHMDTrackingOrigin::Floor:
        Space = XR_REFERENCE_SPACE_TYPE_LOCAL;
        break;
    case EHMDTrackingOrigin::Stage:
        Space = XR_REFERENCE_SPACE_TYPE_STAGE;
        break;
    default:
        break;
    }
    XrExtent2Df Bounds;
    XR_ENSURE(xrGetReferenceSpaceBoundsRect(Session, Space, &Bounds));
    Swap(Bounds.width, Bounds.height); // Convert to UE coordinate system
    return ToFVector2D(Bounds, WorldToMetersScale);
}```

[hard relic]

Find it!
Files can't be .mov
They must be renamed as *.mp4

[sonic lake]

The Quest (and Android in general) does not like to eat Apple stuff

[rocky nexus]

connect to vrd and start like that "C:\Program Files\Virtual Desktop Streamer\VirtualDesktop.Streamer.exe" "D:\DEV\ue\UE_4.27\Engine\Binaries\Win64\UE4Editor.exe" "D:\DEV\ue\projects\UE4271Template\UE4271Template.uproject"
tho it seems it doesnt work with openxr, so theres that

[sonic lake]

UE5 main branch, is it supposed to already work properly with VR?

[sturdy coral]

I think nanite still doesn't does it?

looks like they are getting close to release with possible feature lock downs

 * [new branch]                ue5-release-engine-staging -> EpicGames/ue5-release-engine-staging
 * [new branch]                ue5-release-engine-test    -> EpicGames/ue5-release-engine-test```

[sonic lake]

Even without nanite I am getting crashes

Didn’t try hard though

[sturdy coral]

I haven't tested it in a while, the ue5-main does allow migrating from 4.27 to 5 now, so a bit easier to test with current projects

[sonic lake]

Took the lazy approach to just test the built in VR template

Crashes as soon as I hit VR Preview

Now it’s rebuilding with the latest commits

Not good C:\Users\marco\source\repos\UnrealEngine\Engine\Plugins\Experimental\NeuralNetworkInference\Source\ThirdParty\ONNXRuntime_2021_08_22\Private_DML\Windows\core\providers\dml\DmlExecutionProvider\src\MLOperatorAuthorImpl.cpp(488): error C4458: declaration of 'value' hides class member

[sonic lake]

nothing to do with VR of course

[rocky nexus]

half of this stuff doesnt work on 4.27 either so 🤷

[sonic lake]

4.27.1 works well in general

OpenXR is still in the make on the Oculus side

[sonic lake]

This is what happens when I press the Play in VR button in UE5 main

Rendering thread exception:

with a fresh project based on the VR template

[sonic lake]

For the records, UE5 main, Forward Renderer, OpenXR --> Play in VR from an empty project --> no crashes

[fiery cloud]

You may need to disable lumen, it's the default even in the vr template I believe

[sonic lake]

I assumed it would default also in the Base template

I am going to check

[fiery cloud]

Also, probably want to make sure that shadow method is set to "shadow maps" instead of the new virtual shadowmap system, if that has been set on by default

project settings -> rendering somewhere

[sonic lake]

ok thanks, as soon as it is done with the shaders

[fiery cloud]

Haha, time for a drink
