[real needle]

I have a Quest 2, Link cable, link app and Steam VR installed

I don't know if Steam VR is useful in this case ?

I Can run my PC Oculus soft in the Helm. I Can launch the Steam Room too

[tawny halo]

you have to use the drop down menu and pick play in vr

and I think there is an option inside project settings to start in vr

[real needle]

With the Oculus Plugin Enabled I imagine

So. It Can be done, wich is a good news for now

[maiden willow]

Keep in mind @real needle that this will show you how the game/app will play using your PC's specs and not how it will look and perform on the Quest 2

[wheat holly]

It finally works! Although it feels pretty weird, I think I should add a force to the rotation instead of directly setting the rotation equal to the controller rotation. Then when hitting an object it should flat out on the surface instead of keeping the rotation.
https://gyazo.com/14bf7a3edb295ea8f1727e7e4cc9bb57

And a second issue is that it doesn't snap back to the controller when not having a direct line of sight with the cube and the matching controller. (As you can see at 4 seconds in the GIF)

Although I suspect maybe real games do that as well to prevent weird ways of having to teleport it and then suddenly allowing users to go through objects.

[real needle]

Thank You, so what is the good way to work to develop for the OQ2 ?

[maiden willow]

Functionality can always be tested in the Preview mode - does the logic work kind of thing. But performance will always have to be tested by launching or packaging for the Quest 2

[blissful bear]

It's a very good idea to implement a desktop pawn for your project that you can use to test and iterate without having to put on your HMD (as much.) Trust me, it will speed up dev no end and you can explore the option of having a desktop mode in your final product (it can make sense for arch viz n stuff)

[balmy scarab]

Is anyone else having issues getting quest 2 to work on 4.26?

I have crashes on open level, doesn't seem to matter what level...

[short laurel]

@balmy scarab Yes - there has been a standing bug with Open Level for a while now. Some people have had luck using ARM7 instead of Arm64. There is some discussion on Oculus forums and UDN

[balmy scarab]

oh man I think I recall seeing that mentioned

[short laurel]

I think I am having the same issue opening sublevels on Oculus 4.25 branch currently

[balmy scarab]

I cant sign into UDN the 2fa email gets to me after it expires, haha

[short laurel]

yeah - signing into udn is always flaky for me too

[balmy scarab]

I tried Oculus branch, couldnt get marketplace plugins to work with source, apparently its a thing too

[short laurel]

i have a few plugins working - try copying them to the project instead of engine

probably depends on the plugin though

[balmy scarab]

they work in editor but will not package

[short laurel]

that is annoying - are they compile errors or literal packaging errors?

[balmy scarab]

they "skip loading" during packaging because they are made with 4.25.0 and not 4.25.4, even though I dl and installed to launcher engine 4.25.4. Launcher happily packages them...

The warning/error when I launch project: "The 'xxx' plugin was designed for build 4.25.0. Attempt to load it anyway?"

And when I package the log warning: LogPluginManager: Warning: Plugin 'xxx' is not compatible with the current engine version (4.25.0) LogPluginManager: Display: Skipping load of 'xxx'.

and then packaging fails because it can't find the plugins

[short laurel]

yeah - try moving the pluging to the project/plugins directory maybe?

[balmy scarab]

i have not tried that, maybe it will force it to package as its IN the project?

[short laurel]

btw - the open level crash is caused by an ensure failure (ensure(Scene->GetShadingPath() != EShadingPath::Mobile);) triggering a callstack walk which android disallows

[balmy scarab]

yeah i am looking at that right now

[short laurel]

if you copy to project, you can edit it more easily

[balmy scarab]

is the open level bug in oculus branch too?

[short laurel]

yeah

[balmy scarab]

F***

latest is newer oculus sdk too

[short laurel]

i think you could comment out the ensure failure to get past the XOM stuff...but not sure if there is another underlying problem

[balmy scarab]

2 point something

[short laurel]

to be clear - i had the issue on the oculus branch from around october

not 100% when it was last updated

lemme check the version

[balmy scarab]

pretty sure thats still the one they are on

4.26.0 is 1.51.0

latest oculus 2.something

[short laurel]

1.55.0 and 4.25.4

[balmy scarab]

hmmm

I think I heard a rumor UE4 has new engine version in a few weeks

maybe oculus will have new sdk in that

and all this will be a bad dream

I will try arm7

[balmy scarab]

arm7 does work, also vulkan works again in 4.26.0 which is nice

I feel like every other version vulkan on quest gets broken.

[short laurel]

good to know arm7 works

arm7 is slower?

[balmy scarab]

My understanding is that it is. I am not seeing any issues atm though.

Last time I made an AR app in unity, arm7 was awful performance, basically unplayable. arm64 fixed it

that was on a pixel 1...

trying the plugins in project, UE4 didn't like that so gonna have to do a rebuild I suspect.

Ideally I would prefer to be on latest sdk if it gives me arm64

[celest spade]

Are there any example VR projects using the OpenXR plugin? I've done a bit of VR dev in Unity (which recently added an OpenXR plugin) and wanted to take a look at Unreal, but it seems like the default VR scene relies on using SteamVR components, and I can't find a single thing in the documentation about how the OpenXR plugin works

the page for developing in VR doesn't seem to have been updated in a while either

[short laurel]

@balmy scarab Assuming its a c++ project, just copy the plugins from engine into /projectname/plugins. then generateprojectfiles.bat. Having plugins in project or engine is definitely 100% supported configuration

In order for Plugins to be found, they must be located in one of the search paths for Plugins, either in your project, or in the Engine itself.

[trail shale]

If you set a widget texture the special spectator screen, that's not really any more performance loss since it's already being rendered to the spectator screen itself right? you aren't doing a 2D render target or anything

[trail shale]

I heard the new steam VR beta works with OpenXR

[balmy scarab]

I am sure they will work in editor, whether they package or not is the question

still get the warning launching the project...

[short laurel]

ahh gotcha - misunderstood thought u meant they didnt work in project

[gusty cedar]

anyone know why im just seeing a brick wall when I try to launch on quest 2?

https://gyazo.com/cb4d006ac46b145ddaf86cc0b62da319

what version is best for vr dev

seems like everytime I run into a crash and google it is "Ah yea that happens on 4.x"

[sonic lake]

@gusty cedar I would stick to 4.25 right now. 4.26 is relatively "new" and you can expect still some issues with it.

To your other question, is that wall part of your level? Are you possessing your VR pawn properly? Otherwise what you see may be the standard fall-back pawn placed in a "random" location in your level.

[gritty ledge]

My Action Manifest does not seem to be generated correctly. As I understand it unreal should have also
automatically generated a vector 2 otherwise I can't bind the Thumstick position with the seamvr overlay. Did I maybe do something wrong with the naming convention of the axis names? I am using unreal Engine 4.26.0. Thanks for any help I can get.

[gritty ledge]

Same problem with Unreal Engine 4.25.4

[sturdy coral]

@gritty ledge name them the same

it looks for an x and y suffix

so instead of backward y and right x, name them 'Move_Y" and "Move_X"

the prefix before _X _Y has to be the same

for them to get combined into one 2d axis

[gritty ledge]

Works now thanks 😃 👍

[sturdy coral]

np

[marsh ether]

This mentions OpenXR, as well as MMR, Oculus, Steam, etc:
Seems generic and not too old (Nov 2020?)
https://www.unrealengine.com/en-US/onlinelearning-courses/getting-started-in-vr-with-unreal-engine
I'm about halfway through and it is - admittedly - oculus heavy.

[celest spade]

Thanks, taking a look at it now

[tired tree]

OpenXR is still early stages

its getting there, but it has some issues in engine still

[gusty cedar]

nope that wall does not exist anywhere in my level i don't even know where that brick texture came from

This is what my texture is supposed to look like:

this is what it looks like in vr:

I don't like how saturated that green is, anyone know why that's the case?

[celest basin]

Aight

Anyone here devving on an Oculus Quest 2?

I'm considering buying one depending on how it works with UE4

[paper epoch]

Hey guys I am using an Oculus quest 2 with a live link cable to use like a Rift S. My current project is giving me 3 FPS only while giving a good fps in non VR. What could be the problem here?

[blissful bear]

Q2 works great with Unreal. Or at least it used to! There are some teething troubles with the latest versions of UE but you shouldn't let that put you off.

[celest basin]

Just watching a youtube about it... seems to be very android focused

prolly not that interested in mobile dev tbh, would just want it for doing (making) PC VR

[blissful bear]

You can use a link cable that lets play and dev PC VR too. It works great.

[celest basin]

Sweet, so with the cable it's pretty much(ish) like with a vive?

[blissful bear]

Yes!

[celest basin]

Still adjusting to the idea of being cavity searched by facebook everytime I want to use my VR headset

[blissful bear]

I know. It's disgusting.

Great subsidised HW though!

[celest basin]

Those two lines seem to sum up everything I've been able to find out about it so far

Good to know that the PC side works but, ta 🙂

[blissful bear]

np

[celest basin]

How do you find the battery life on the controllers?

Had a HP MXR for a while, burned through batteries in a night... (a big night, but a night)

[blissful bear]

I've not had to replace them since I got it when they were first released... Good I'd say

[celest basin]

Sweet, I'd say that puts me one and a half feet over the finish line then

[blissful bear]

You only need the 64GB version unless you plan on having a game library. It's good value for money

[celest basin]

oh sh#t, forgot about that

don't really matter but, only really interested in PC VR

[blissful bear]

I'd recommend choosing a good 6m Link cable and you need a fast USB 3.x port on your PC

[celest basin]

I should just get the one from oculus no?

[blissful bear]

Yes, that's prolly safest but not cheapest solution.

While I'm recommending stuff, you should have a look into using the VR Expansion plugin for doing UE VR dev if you're not already aware of it.

[celest basin]

I played with that last year (on a vive from work)

Got out of my depth pretty quickly

And my hobby project is planetary terrain in C++ in UE4

[blissful bear]

Good stuff! You know that the new 4.26 sky, cloud and water system doesn't (yet) work in VR. Might be a problem?

[celest basin]

Cloud would have been nice but oh well

What about volume fog?

[blissful bear]

I'm not sure tbh. You'll have to choose between deferred rendering (awful AA but more features) or forward render (great AA but no fancy stuff) which probably matters for volume fog. You'll have to try!

[celest basin]

Aight, I'll do me some more googling... thanks @blissful bear

[blissful bear]

Good luck man!

[tawny halo]

Has anyone worked with multiplayer on Oculus Quest? Does Oculus provide some Online Services? Is the device even capable of running a listen server or are dedicated servers required?

[tired tree]

@gusty cedar that brick texture shows up as the default when shaders aren't fully compiled.

[quaint steppe]

I can't seam to get "Is Guardian Configured" to run true on Q2 with link. Is it rift only?

oculus subsystem is enabled

[paper epoch]

Guys I need some help. I am getting very low fps in VR in the editor but it runs fine in the build. Why could this be happening?

[maiden willow]

@paper epoch have you tried running just the default VR Template to compare? You may have too many triangles in the scene, or your materials may be too expensive, or your textures are too big, or any number of project specific settings. The broadness of your question leaves much for interpretation and no one would be able to assist directly and precisely. Start with the blank template and then add from your current project until you find the issue unless you get someone to actually look at your project

[paper epoch]

yes I did same issue

The exe runs fine and I checked shader complexity and its almost completely green

I used to work on my friend's rift S on the same hardware and faced no issues. I am currently using a quest 2 with a type C cable, my older builds , builds for the older version of the project I am working on and the current version work fine

disabling HMD via console also makes the lag stop

[maiden willow]

are you using 4.26?

[paper epoch]

25

[maiden willow]

I'm not sure then, I know others have advised issues with 4.26 and VR. There shouldn't be any difference between using a Rift S and a Quest 2 with LINK.

[paper epoch]

I know

I have a 15 Jan deadline and I cannot test the app in VR which is important as all I was supposed to do was integrate REST API into a project which was worked on by another dev 😦 with crappy coding and a lot of junk files

[gusty cedar]

I created a facebook account just for my quest lol

[sudden glade]

Hey, guys, is anyone know why i opened the ARScene& ARPawn, everything is works, but the camera is keeps black? I'm using source code 4.25.1(ARCore on android)

[real breach]

Is anyone able to help me with Robo Recall mods?

[hallow knoll]

@real breach It's better to ask your question rather than just asking for help - if someone decides to browse the channel and they know the answer they can then respond

[real breach]

Why do some of my mods crash in game?

I have the Z saber mod and it crashes the game every time I load a stage.

[sonic lake]

If there is a crash there should also be a crash log. Did you look into it?

[real breach]

I always closed out

Lemme grab it then

And the lightsaber mod doesn't activate the lightsaber, I can't seem to fix it

[real breach]

Wait nvm Z Saber works

[celest basin]

Welp. I'm officially a brand new owner of a Quest 2

Take a week or two to get here of course

[abstract forum]

Nice

[tame lynx]

Hey guys! Running into an issue where Render Targets are showing as Black on Quest (android). My google-fu has showed me that other people are definitely experiencing this problem, but that it isn't solved yet.

Does anyone have any wise words?

It was apparently an issue in 4.9, and 4.11, and they've fixed it twice now. But it looks like 4.25 broke it again.

I've come to understand its busted on all android decides -not just the Oculus Quest.

[abstract girder]

Yep, I've done it in the past. I've only done it over the local network though. There's an Oculus online subsystem, I've not used it though. It can run a listen server just fine, I was hosting on the quest and connecting with other windows/android devices.

[tawny halo]

Thanks, thats good to hear

[real needle]

Hey, i have a 2d render target and it works great in ES3.1 simulation mode but on my quest 2 it renders upside down somehow
I haven't been able to find much information about this issue with google, im on 4.25.4

[tame lynx]

Hey @real needle I'm facing similar issue too -see my message just above this.

As far as I can tell, render targets aren't really well supported on Android, and keep breaking.

This doc has some interesting info: https://answers.unrealengine.com/questions/955665/mobile-vr-multiview-render-to-texture-is-black.html

I am looking into MultiView now

[real needle]

I was able to get around my issue with pre flipping the texture, but this isn't the most ideal solution
I'm using forward render and nothing else, because as I understand multiview, forward rendering, hdr and instanced stereo break each other, so you can try using one at a time

[tame lynx]

Are you sure the plane isn't just flipped upside down

[real needle]

it works great in the editor

[shy merlin]

What SDK and NDK versions are you guys using for deploying to Quest 2 in 4.25 oculus branch?

[shy merlin]

I switch to SDK 29 and now my app is building to black

[real needle]

@shy merlin with quest 2 you should set target sdk to 25 and im using ndk-19

[fair cairn]

I am buying a quest 2 for our studio. It's main use will be gamdev for our current project, but it'll also be used for some beatsaber when we erm..... feel like erm.... researching? yeah let's go with that.

Anyway, as gamedev studio, which version should we go for, 64 gigs or 256? For personal use I'd for sure take the 64gb version, but idk how space intensive vr dev is for untethered headsets.

[blissful bear]

64 GB is plenty of room for dev and taking movies/screenshots of your projects. It's Android mobile based and a 10 GB packaged install on the device would be a huge project.

[fair cairn]

Thanks!

[sudden glade]

Hey, guys, is anyone know why it's not create "UE4Game" folder in some Android devices but works on other devices ?
This is something very strange when i install the AR App on the Android? Is anyone ever meet this kind of problem？

[reef lily]

I recently got a hp reverb g2.Now I have an issue where my project only seems to run at 45fps capped instead of the 90 the headset is supposed to handle

The scene is super simple and it doesn't matter what settings I turn down, it always stays at 45fps

Previously it ran at 90 on my oculus CV1

I don't know if it has to do with UE4 or SteamVR? Heard mentions of reprojection in SteamVR doing that, but can't even find the settings for reprojection in SteamVR. Not sure if they've removed that as an option

Only way I can get 90 fps is to go into project settings and check "use fixed frame rate" and set it to 90

But that doesn't seem ideal

If someone has a vive it will be lowered from 120 to 90 for them

Okay even then it's just the in-game fps monitor I made that reports 90. It feels just like 45 if I wave my hands around

[shy merlin]

Has anyone encountered this crash with audio? Or see me doing something blatantly wrong with audio caching? https://answers.unrealengine.com/questions/1006202/quest-2-apk-crashes-from-sound-cue-with-random-nod.html

[mighty carbon]

Has anyone figured out how to use Quest 2 with UE4 wirelessly via VD? (so that when VR Preview button is pressed in the Editor, the project runs on HMD)

[gritty elk]

hey im very new to unreal engine and i have a problem that i cant seem to fix. im working on a vr project and my hand controllers dont seem to be working and i cant figure out why. i dont know if i did something to make them like that but idk

[sour charm]

Hello, we are trying to get networking to work in a VR game and whenever the client joins the listen server, the host can no longer move. We've paid for a couple networking blueprints and have searched for solutions online, but nothing seems to point to what the problem is. Anyone have any ideas? (Sorry if this is the wrong place to post this.)

[sour charm]

they don't work at all or is the issue only when you package the game?

[gritty elk]

when im working on a project and go to test how it works in vr mode my hands wont be near me and i cant pick up anything or move around

[sour charm]

if you create a new VR project, is it still an issue?

[gritty elk]

yeah it still wont work

[formal peak]

I have imported a 3d model into a vr game, and it does not show up while launching the game. It does show up when I press play in the veiwport though. Does anyone know why this is happening?

[sonic lake]

@gritty elk which HMD are you using?

[wheat holly]

I feel like such an idiot, I just figured out that I can pause the game when in VR and then look at all actors etc. xd

[tepid fossil]

Hey guys, has anyone succeeded in making XR loading screen work in 4.26 - 4.24?

[proper anvil]

hi guys, how's it going? I'd like to switch off my monitor while the HMD is on. Does anyone know the cmd for it? Thanks

[gritty elk]

i have an oculus rift s

[sonic lake]

Does it work at all out of Unreal? Are the controller batteries fully charged?

[opaque gorge]

Does anybody know how to have AI perception work with a Blackboard? This has been a thorn in my side for well over a month and I can't seem to have the AI see my VR character

[gritty elk]

yeah everything works outside of unreal

[sonic lake]

Is the oculus plugin active and all the other VR plugins not active?

[gritty elk]

i think theyre both active

[opaque gorge]

I'm going to go ahead and wait in line for a bit

[gritty elk]

actually only oculus and steam vr are active

[sonic lake]

You should try disabling SteamVR

[opaque gorge]

@sonic lake
Hello good sir can you help me with something

[gritty elk]

it looks like i have to have steam vr enabled. when i did it i couldnt load anything vr

[sonic lake]

@opaque gorge please ask your question here someone will help you

@gritty elk do you have the Oculus software installed? It should work without SteamVR and just with the OculusVR plugin

[sly elk]

I'm not seeing any of the cosmos bindings in 4.25.3. Were they added in 4.26? I can also manually type out the steamVR json but that will be cumbersome

[gritty elk]

i should have everything for the oculus installed

[sly elk]

@gritty elk You are doing PIE through the "play this level in VR" button, right?

if so, when you are in the game without working hands, and you press the home button, do your controllers suddenly work in home?

[gritty elk]

yeah im running it throught that. and yeah my controllers work outside of it as well.

i can double check

im thinking that im missing something with the vr pawn

because my controllers work in the vr editor

@sly elk

[sly elk]

I haven't made a VR template project since like 4.16ish but it should work unless you edited the pawn

or the motion controller BP

Do you have anything in the logs?

[gritty elk]

i think i mightve on accident and not realize what i did or that i did anything \

but idk how to check the logs

[naive fox]

Hey guys, I am working on a roomscale VR setup, and there are certain parts of the real world, which I want to line up with the vr world. I need a way to accurately align these through some kind of calibration step in vr. There is a table in the room, so I am thinking of maybe placing the controllers on 2 of the corners of the table. But how would I then move/rotate the player to line up?

(in BP preferably)

If its possible to do it just with the headset, e.g putting the headset down on the corner of the table, that would be good since I hope to use hand tracking

or maybe there is a way to align it with hand tracking?

[short laurel]

Maybe just position the table to the controllers? ( as the headset is already calibrated)

[naive fox]

I thought that yeah, but there is a lot going on in the game so it would be quite complex to offset everything.

[tepid fossil]

Hey guys, has anyone succeeded in making XR loading screen work in 4.26 - 4.24?

[urban igloo]

@naive fox Having player start line up with the calibration point irl isn't enough?

[formal peak]

Is there a way to change the maximum number of bones allowed in a mesh

[urban igloo]

@formal peak Doesn't sound like a vr question. You'll find anwers easier in a different channel

[formal peak]

Ok thanks

I was asking because it was affecting vr

[urban igloo]

Tried 4.26 anisotropy with a pimax headset, but only the right eye gets aniso shading. The left eye sees normal highlights. Send help.

[naive fox]

Putting on the headset means that the calibration point can't be an accurate point.

[spiral oasis]

does anyone know if there was a weird change with UMRMeshComponent no longer allowing you to change collision profile (or object type?) on 4.26? it worked on 4.25, but setting the collision profile in OnAddTrackedGeometry is breaking collisions on 4.26.

the custom collision settings are working fine with regular meshes. it's only when testing on device with UMRMeshComponent that it's broken. leaving the default collision settings works as expected, but we need the custom collision settings.

just tested the same custom collision profile setup on a new project - same results. no collisions after setting up the profiles and applying it to the UMRMeshComponent.

[sudden glade]

Hey, guys, is anyone know what's going on about this? I package the package for windows, there is no problem but also showing this message when i open it, and i didn't find that “GoogleARCoreCameraOverlayMaterialLoader”, is anyone can give me any advice to clear this one will be very appeciate

[sudden glade]

Oh, it might because the source engine 4.25.1, cause when i i try to open this "xxxloader", i can't find this file the explorer

[urban igloo]

Someone, please try:
1- Opening collabviewer in 4.26
2- then connect a 0.8 scalar to Anisotropy
3- with a vector of 1,0,0 connected to tangent

[urban igloo]

this will cause the highlight to appear only in the right lens, but you can use Instanced Stereo to force it on both

[blissful bear]

Get a 64GB Quest 2

It's the best value for money and does everything you need for dev.

Get a Link cable also for PC VR dev with it.

I also have a Vive but the Q2 made it obsolete.

[blissful bear]

That's a WMR headset? Good luck with that although I hear it has upcoming support for SteamVR maybe. It seems twice the price also and doesn't work without a PC.

Once your clients try wireless Quest 2 VR they will want builds that work that way, it's a much more client friendly product but presents dev challenges to optimise for the native mobile hw

[tired tree]

he is talking about editor tools

WMR if fine and a good price point for devving on that

he won't need standalone

[blissful bear]

Standalone is a bonus for 'free' but you are right it's not required. I've come across plenty of forum posts highlighting problems with WMR but I defer to your superior knowledge. SteamVR support must have improved since I last looked.
One thing that the HP has going for it is that no FB login is required, so there is that.

Sorry? I was agreeing with Mordentral

No problem. Good luck man!

Hey man no bother. I can be clumsy with replies, I'll try and improve. Let us know how you get on with whatever hw you decide to get!

[clever iron]

You also don't need to by a link cable, the 2.0 cable that comes with the oculus to charge also works as a link, been deving just fine with it.

[short laurel]

@small grove Thought I'd toss in my two cents - I've got both a Quest 2 and a Valve Index. Both are pretty awesome. Can easily recommend either one. I typically use the Index for any PC VR .. the link cable / Wifi Virtual Desktop, while impressive, still not quite as good in terms of latency imo. But untethered the Quest 2 is simply awesome.

[sly elk]

Index grip input appears to have changed in 4.26..

getting my index setup now. Anything I should know?

[tired tree]

They just renamed the button

Have to replace it though, old binding crashes the engine

[jade kettle]

Is there support for the Index controllers in 4.24?

[sly elk]

not really

VR input totally changed in 4.25

Has anyone here set up vive cosmos controllers? We don't have any to test with but I am trying to come up with inputs for our VR players. Setting up binds is easy enough, it looks like a rift controller. What im not sure about is the controller angle. It looks like a rift controller but does it have the same origin transform?

[somber storm]

Hi there, I'm new here. Are there any VR emulator for Unreal? I wanna learn to develop for VR but I don't have a headset.

[gentle hamlet]

I got this error when launching to Oculus Quest using UE4.25.
I have support for Vulkan, Multiview ON, and using MSAA.
The same project settings works fine in 4.24.
Anyone get any idea about this?

[sonic lake]

@somber storm short answer: no, there is no VR emulator in the engine. However if you need to build a VR environment you can do it with the regular tools and explore it using a regular (2D) pawn. Eventually though you will need to test using a real VR headset and motion controllers.
Long answer: a VR experience has 3 main components to it:

1. being able to watch the world you are in by turning your head or moving it in any direction.
2. interacting with the world using the motion controllers (or bare hands), for example picking up and throwing objects.
3. moving inside the world (with teleportation or other ways) or moving in real life and expecting the same movement within the virtual world (room scale).
   I think you can easily reproduce (1) by controlling a regular camera with your mouse or a gamepad. (3) you could also emulate to a certain extent by "faking" it with the keyboard or other controls. (2) is really difficult because you would need to emulate 2 hands each one with 6 DOF, plus the grab/release controls. It can be done but I would not call it a VR emulator.

Hi, is someone here using Azure Spatial Anchors for AR? I'm curious to know how to update to version 2.7 as the current version apparently won't work after February.

[rich canopy]

If you need one, do apply for the oculus start program. They will send you one of their refurbished headsets for development purpose. Might take a while to get delivered to you but you will get it.

[real needle]

Im trying to use AZure Spatial Anchors. Im not sure about the update. I do have question in regards to having anchors found through the watcher. it seems that after a ASAAnchor Located Delegate is activated and a watcher is created, the watcher is not located the saved Cloud Anchor. If anyone has insight please let me know. the bound event to the Delegate dosen't seem to do anything.

[mortal surge]

I'm also trying to get Azure Spatial Anchors to work (on Hololens). The node "config session" changed to "config session 2" and behaves differently and I can't get it to work? Anyone know if there is a different method with this new node?

[worthy quest]

What exactly doesn’t work?

[mortal surge]

When I try to save a pin to the cloud it says "constructCloudAnchorFailed"

[worthy quest]

I‘m writing a thesis about it and have thus worked with ASAs quite a bit now. I can send you a working example if you want. It‘s however untested with the hololens

[mortal surge]

That would be great thanks, that way I could at least see the correct method and check mine against it

[worthy quest]

I‘m at work right now but you can hit me up later today or tomorrow 👍

[tame lynx]

Does anybody know how I can minimize the VR Spectator Screen?

The best I can do is set it to a black texture.

[mortal surge]

Thanks will do!

[nimble edge]

I have most headsets, and if you are looking for a tethered PC headset, the G2 is really nice. The resolution is really good. I haven't had any problems using it with SteamVR. I still prefer to use my Index as my daily driver because of the 144hz refresh rate - It makes a big difference in comfort for me.

[modest cliff]

[ARKit/IOS] Could someone from Epic or the mods please verify that only Apple devices with the A12 Bionic Chip or newer are supported with engine version 4.26 when using AR Kit?
I wasn't able to get our previously well working Apps running with 4.26 on older Apple devices and would be happy to spare the time trying to get it to work, when it's not possible in the first place.

[quiet swan]

someone please HELP! I think 4.26 BROKE VR. I am working on a VR game and saw my character wasnt moving in client mode, now it turns out unreal did something with the way the VR is played back on multiplayer! For example, they told me to put this code in the tick of the character to see if it updates and it did NOT update in client mode.

as you can see it does NOT update for the second picture which was taken in client mode. the numbers stay as x =-50.000 y=0.000 z = 170.00. They said unreal did something with this 4.26 and broke things in VR. So I need to know, is 4.25 going to be the last working VR engine?? what a nightmare if it is, as we wont get the updates anymore

[tired tree]

@quiet swan ???? its working fine in 4.26

engine doesn't handle multiplayer vr at all anyway

[quiet swan]

@tired tree does VR in 4.26 use editor window and not stand alone window?

[tired tree]

it uses its own launch still, but you should be able to test local multiplayer with it

local multiplayer with vr straight up didn't work before 4.26 anyway

aside from dedicated server emulation tick

[quiet swan]

I dont understand, I have been testing VR in client mode in 4.25. I would just play as client and test in the editor to see if things were replicating, but in 4.26 my character is stuck in client mode

[white gulch]

What's the best way to load a packaged game on an all-in-one headset? Is there a "best headset" for this sort of thing?

[trail shale]

How do I murder steamvrtours.exe?

[arctic saddle]

Is there still no good way in detecting if the user has the headset on or not? It causes problems if the user already has the headset on sometimes, and it doesn't switch scenes to a idle 2d screen half the time when the headset is not on somebody.

I've tried, worn state, vr vocus, and valid tracking. None seems to be working consistently... I have it setup to check every 30 seconds or so if the headset is on or not via tick. if state has changed, go to idle screen. in the idle screen it just detects if the headset is on without delay, as soon as they have the headset on or moves, it goes back to main menu. But it seems it's not as easy as it seems...

[trail shale]

@arctic saddle have you tried getting the velocity of the HMD

[arctic saddle]

@trail shale How does one do that? Never thought about that way funny enough. Would it be the forward vector?

I'd assume that would be the velocity of the VROrigin/Camera itself?

[trail shale]

@trail shale sorry, I was thinking this the actual motion controllers - I remember I needed them to be detected movement or not, not the HMD

@arctic saddle

[arctic saddle]

Hmm. Ya. Not so much help with controllers. But I do like your idea of maybe the pawn velocity itself. I wonder if that would work the same way? GetMotionController()->GetVelocity() kind of deal and have it within a small margin

[kind echo]

Does anyone here have any tips on how to get dynamic shadows posably Modulated shadows working with mobile VR and Vulkan?

[clever iron]

I would caution that dynamic shadows are super intensive for mobile VR. Superhot has a video about how they handled shadows just to get their game working under 72fps

er, above 72fps*

but besides that, no tips

[kind echo]

I only want it for one or two objects but I'll keep trying to figure it out, thanks.

[proper cedar]

Hi, I have been programming for years on VR with htc vive but I would also like to take an oculus quest 2.
Can I also program without the oculus link cable?
And what changes if I have it instead?

[blissful bear]

Yes you can. You need to package for Android and be aware that you are now running on mobile hw rather than pc. You may need to optimise your scenes. 4.26 has problems currently, hopefully fixed in 4.26.1. Good luck

If you have a cable then your projects may work as is under SteamVR but you'll need some changes due to controller differences etc

[proper cedar]

OK thank you very much!

[willow trail]

My post process material has stopped showing on both eyes (now only on the right one).
Anyone knows why that could be? It's been working fine for a while, but after switching to 4.26 and attempting to use GPULightmass (turning on raytracing and virtual texture, and then turning them off again when I realized GPULightmass doesn't work with forward rendering at all), one eye just stopped working (solid black). I had to disable instanced stereo to have both eyes again, but the post process remains broken

[quiet swan]

can someone tell me which node is causing the issue? When I click the branch at the end of the error it brings me another area of the code of the is valid

it takes me to this node

[rocky nexus]

is there a way to make stat unit and friends be sorta usable in vr? especially on Q1 its quite hard to read :/

[daring pasture]

@trail shale steamtours is steamvr home. Disable home in steam vr settings and it will stop opening automatically.

[viscid moat]

@willow trail if you can reproduce that in a fresh project I would submit a bug ticket for them to try and get the fix in for 4.26.1 if possible.

[viscid moat]

Here to save some people some time/headache with an unknown crash in 4.26 when switching off the "Run Under One Process" in editor settings. You will need to go to your DefaultGame.ini and change "bStartInVR=True" to false. Reported this issue to epic in a bug ticket I had opened a month or two ago.

The crash would occur when testing multiplayer with 2 clients

[pastel pendant]

Hey all! Im learning VR Dev and I am hoping you guys can help me grasp what makes VR different from flatscreen (besides the obvious). For example, can a sniper asset for flatscreen work for the player in VR? If not, can it be converted to a VR asset? How does the CG/modeling differ in flatscreen to VR? How does rigging change? How to optimize these assets for VR (besides your normal low poly)? Thanks!

[rocky nexus]

the way i see it, its not very different than regular flatscreen 3d dev. main difference is the way you interact with the world, assuming first person game. dunno what a 'sniper asset' is. for vr you need to run at very high refresh rate and resolution. you need to use every possible trick to get stuff running as efficiently as possible, especially for mobile vr

[pastel pendant]

Sniper as in a gun. So your saying you could use a very well optimized wall asset, for example, for both a VR and nonvr game?

[rocky nexus]

both are 3d

not a whole lot difference between regular first person 3d and vr, but one can run at 30fps and other minimum 72

as far as the sniper rifle goes, you can probably use the model. but you need a way to hold it with controllers and reload it and stuff like that

it cant just float in front of the camera

[pastel pendant]

right so you would just have to attach it to a socket on the player hand and rig it for a reload animation or something. I only wonder how you would blueprint when you put the clip close to the gun to play the animation... I can think on that later though. Thanks!

[rocky nexus]

most likely all of that should be physics based

play with https://vreue4.com/

and some actual games :p

[quiet swan]

is it possible to test VR games playing as listen server? I can test with 2 players, but if I add 3 or 4 it crashes,

I have 1 headset

for example I am trying to see what happens when 2 VR players spawn in the game, as they keep spawning in different places

is this something that can be tested this way?

[clever iron]

with two headsets?

or just one?

[celest basin]

So... I've installed the VRE plugin... migrated the Vive_PawnCharacter and Steam_VR_Player_Controller into my project

Setup all the action and axis mapping

But when I play the head movement is all wrong

Goes in reverse direction, can't turn all around... it's almost like it's loosely tethered in one direction

Where do I find the bit that controls the camera/head rotation to check it?

When I play the VREP demo project it's all fine

Mmm... something funky through my game mode, ditched that and it came right

[celest basin]

Nah, I'm ditching VREP

Welp that was a fun night. UE4 VR stubbornly refused to let me stand any taller than a freaking hobbit.

[twin heart]

Hi Guys, i work with a fullbody mesh vr character. The Problem is i see trough his head... how i can make the head invisible for me but not for other multiplayer?

[viscid moat]

If you had a separate mesh for the head you simply check OwnerNoSee to true so that you can't see it yourself. If it's all one big mesh you can scale the head bone down to (0, 0, 0) and that should work as well.

Or you could have two meshes one with a head and one without and do OwnerNoSee on the one with.

[twin heart]

Ah nice i try the second one, bit how i can apply 2 meshes to a player pawn?

[viscid moat]

Attach two skeletal meshes to the character capsule and set them as regular and headless mesh

Then click owner no see on the full one

Or you can attach the headless one as a subcomponent of the regular mesh

[twin heart]

Thanks that should work 👍🏼

Hello,

I am having issues with the Index Output.

On the oculus there is no lag at all with the HMD but on the index it seems to be an issue that the head movement lags.

Any help is appreciated thank you

[dense tendon]

Hi all,
I'm trying to display stereo camera as passthrough cam in unreal engine, the stream is in 720p SBS output. I don't know how to post process and split the output and display the corresponding image on corresponding eyes. Google gives me old technic and I'm sure there is all optimized and simplified functions in unreal. Thank you for your attention.

[wheat holly]

Do you know how much frames the Index you use needs? I believe the Index can be set to for example display 120 frames per second. Oculus can't reach that amount, so are you sure the PC you're using can handle the amount of frames the index needs?

[grave wren]

PC specs are:
i7-9700k 3.6 GHz
16Gb Ram
and an RTX 2080 Super
So personally that should handle 120fps without a problem

Within editor 120 fps are reached as well

[limber plank]

Quick q: How can I tell whether the player is using HTC Vive or Valve Index? As far as I know, there's a function called "GetHMDDeviceName" but it returns the platform (SteamVR), not the device

[quiet scaffold]

I followed a Full body VR setup, and everything works except for the position of the hands, they are not exactly where my motion controllers are. I'm guessing it's something with the IK setup, but not really sure how to go about troubleshooting that position. Any ideas?

[quiet scaffold]

It looks like the IK setup has the wrist as the point for the motion controller where it actually is from the knuckles. So there's another joint in there that I have to solve. Some progress, just not sure how to do the double joint in the IK now.

Taking a break for now, if anyone has any experience with this, feel free to ping me.

[marble kiln]

Looking to hire an experienced Unreal VR artist for consultation / lessons one hour a week for $50.

[sturdy coral]

@limber plank if (GEngine->XRSystem->GetVersionString().Contains(TEXT("holographic"), ESearchCase::IgnoreCase))

that will tell if it is wmr (if using steamvr, not sure what it would return for wmr via wmr native driver or openxr)

first determine plugin (oculus, steamvrro, wmr, openxr) through GetHMDDeviceName which actually returns plugin name

then use GetVersionString at least for steamvr to determine headset type

for openxr and others GetVersionString might not be the right thing, I haven't tested

GEngine->XRSystem->GetVersionString().Contains(TEXT("oculus"), ESearchCase::IgnoreCase) to test for oculus headset if forcing steamvr driver

you'll have to test if it distinguishes vive and index well, I'm not sure what strings they give. I just used it as a stopgap for WMR to guess controller type if the controllers aren't on yet

otherwise I look at controller model name, because it is possible to use e.g. index controllers with WMR

with openvr space calibrator

[tired tree]

i have the openXR version up @sturdy coral

of the controller type detection

[sturdy coral]

ah nice

[limber plank]

I am using blueprints

[sturdy coral]

@limber plank it isn't exposed but I think we found some hacky round about way in the past through a different string you can query that also includes getversionstring

but you could use mordentral's plugin and get it through blueprint

@limber plank Private/HeadMountedDisplayFunctionLibrary.cpp 68:FString UHeadMountedDisplayFunctionLibrary::GetVersionString() 73: VersionString = GEngine->XRSystem->GetVersionString();

that should be exposed actually there

    /**
     * Returns name of tracking system specific version string.
     */
    UFUNCTION(BlueprintPure, Category = "HeadMountedDisplay")
    static FString GetVersionString();```

[limber plank]

Considering Vive and Index have completely different controllers, I'm surprised there isn't a simpler/BPexposed method. This is helpful though. GetVersionString returns what, the device?

[sturdy coral]

the controllers aren't guaranteed to be different

and there is a different way for checking controller type

index can use vive controllers and vive can use index controllers

[limber plank]

I didn't know that. well then I'll need to know what controllers are being used

hmm

[sturdy coral]

getversionstring I think will have some kind of vendor driver info I can't remember exactly, it could distinguish wmr through steamvr from vive through steam vr, but I'm unsure if it can distinguish vive through steamvr from index through steamvr

I would use mordentral's methods as it is used by a lot of people and he has probably solved the biggest issues

for controller model I had to modify the engine a bit because old disconnected controllers will still show up and getting it from actions wasn't reliable and the engine's default stuff for distinguishing disconected vs not tracking is broken

I have a fix for that here:
https://github.com/EpicGames/UnrealEngine/pull/6990

[limber plank]

is this the plugin you mentioned? where can I get that

[sturdy coral]

okay thanks, I'll check it out in the morning

thank you for the help

Anyone here have opinions about VR and 4.25 or 4.26 and engine stability? I’m thinking about updating, but I’m hearing more and more about editor crashing.

[dusky moon]

Hey all, anyone uses OVRLipSync with 4.26 ?! seems like oculus is not updating the plugin anymore ?!

[opaque adder]

Hey has anybody else had issues with bindings not working in the packaged version of a game? Not sure how to fix it. It works fine in the editor, but not in the build

[opaque adder]

My keyboard bindings are working as they should but there is no response from the controllers

They are tracking fine but no inputs

[obtuse spruce]

@placid spear I abandoned upgrading a Quest hand-tracking project from 4.25 (the Oculus fork) to 4.26 (Epic release). Fixed a build error, then I started getting crashes during play I never managed to debug. Can't speak to any general consensus on whether upgrading to 4.26 is "safe"

[placid spear]

@obtuse spruce thanks for the feedback

[wheat holly]

Until now I've only heard bad things about 4.26 whenever I look in this channel to be honest 😅

[sly elk]

anyone here messed with raytracing in VR?

[proper anvil]

tried it in 4.25 ryzen 9 32gb and a gtx2060. it worked, but wasn't great, around 20 fps on avg. Oculus Rift

getting D3D crashes it both VR and RTX is on, but not too bad

just wondering, where do I find info about what headsets are supported by 4.25.1 by default?

[sly elk]

We have options for raytracing and some of them perform well enough on my 2070 super when DLSS is on. I can't get RTAO to work though and it is the one I am most interested in.

[placid spear]

@wheat holly same here. I’ve seen similar opinions in other channels and some think it’s due to due to relatively new features (chaos, etc).

[urban igloo]

@sly elk Do you use instanced stereo and forward shading?

I can't get my archviz scenes to perform above 30fps on a 2080ti

[wheat holly]

Depending on how large your scene is instanced stereo can from what I've heard make a pretty big difference. But the problem is that not everything works correctly with it. Such as Niagara 😔

[urban igloo]

@wheat holly That's interesting because I found anistropy would only have correct shading in the right eye, and only with Instanced would the shading work on both lens.

[wheat holly]

It wouldn't surprise me yeah, but in my little amount of experience I had issues with it being turned on. For example like I said Niagara, I had to revert my Niagara system to Cascade otherwise I couldn't use it. But issues the other way around wouldn't surprise me as well like I said 😅

Also question, does anyone know if it's intentional or maybe a bug that if you don't have your VR headset on your head regular controllers (like in my case a xbox-one controller) do not work? It only gives an input when I wear my headset, when I pull it off my head it disables the input for the device again. Any way to fix this?

[urban igloo]

@wheat holly Maybe it's HMD specific? I use a keyboard and I haven't noticed losing input with the hmd off.

[wheat holly]

Well that's the fun part, my keyboard works.

But I'm trying to support both regular controllers and keyboard as it's an asymmetrical multiplayer mode. So if people want to use keyboard, go ahead. More comfortable with a controller? Use that! Or it would even be possible to assist someone.

It's not the biggest issue, but it's a bit weird to test with. For people playing I would imagine it not being an issue as you would need someone in VR anyway, otherwise you're not playing the game the right way xD

[violet spear]

https://www.youtube.com/watch?v=Wd5W42HjHxw

[sly elk]

@urban igloo no we are on deferred. We do run instanced stereo.

[viscid moat]

@wheat holly niagara issues are resolved in 4.26. I reported them a while ago and they fixed it

[wheat holly]

You sure? The issue page says it's target fix will be for 4.27 and is still unresolved https://issues.unrealengine.com/issue/UE-78764
Also then there's still the issue that many other problems seem to be in 4.26 compared to 4.25.

[opal prawn]

Hey is there an easy way to switch from first person blueprint to VR? There's no VR character so I'm a tad confused...

Like the First Person Character BP has VR options

[urban igloo]

@opal prawn Check the Collaborative Viewer sample scene. That has what you want. It's gotten a bit bloated though.

[opal prawn]

Awesome will do! thanks!

[viscid moat]

@wheat holly that's a different issue than the niagara issue I submitted. If stretching is an issue then that's something I haven't yet experienced and I am running a lot of niagara particle effects.

[wheat holly]

But do you have Instanced Stereo on?

Also that issue was an example, there are more issues. Translucency for example didn't work for me.

[viscid moat]

Ok well then I guess there are a lot more things than what I reported. I just haven’t run into any of them. And yes I do believe I have it turned on.

[shadow radish]

anyone try out distance field shadows in VR? I have a directional light with some short range dynamic shadows that seems to do okay for performance, but for longer range shadows into big caves I was thinking of trying distance fields

wondering if that is a viable option or if I should just make caves a separate level with static lighting instead

[opal prawn]

Is the index not supported by UE4?

I can't seem to get collab view to work with my headset

oh wait I got a runtime error

[opal prawn]

@urban igloo collab viewer is absolutely brilliant. You're right, it's got a ton of junk in it - but I've gotten my old project to go into VR mode easy. And I think I might actually understand casting slightly better now! Thanks!

[visual steppe]

[crystal ingot]

Hi everyone! I'm having some pretty annoying problems with VR in my project. I've made a post in regard:

https://forums.unrealengine.com/community/general-discussion/1856725-need-help-start-position-in-vr-in-editor-is-correct-but-not-in-packaged-build-4-26

To sum it up: I'm setting up the starting location of the player. Everything works fine in Editor, but when I make a packaged of the game, the starting position is completely off. Anyone have any idea what is going on?

[spiral marlin]

I am looking to have dozens of explosions briefly light up the surrounding area (they do not need to cast shadows). I know this is not feasible in forward rendering. Is there a way to achieve this? Perhaps something that fakes a dynamic light? It doesn't need to be high quality or "correct", as it is a momentary light that flickers with an explosion or bullet.

Desired result: https://youtu.be/97NVvWgRNCA?t=7

[obtuse spruce]

@crystal ingot Unsure why that would be happening

Do you need to use a PlayerStart? Might be worth trying another way, like auto-possessing a pawn instance in the map, instead to see if that fixes the issue

[crystal ingot]

Ok, apparently the build decide NOT to use the game mode I set as the default one. I also set it in the level I'm currently interested in. But when I build, the game is being set with another game mode. How's so?

[sturdy coral]

@frosty osprey check maps and modes section of project settings

may have something different for editor vs packaged

otherwise make sure you aren't opening the level with '?game=[gamemode]' through something you've included

[real eagle]

Is there any way to test a AR application on desktop? using the desktop cam or anything similar? Thanks

[crystal ingot]

Already set that up, the mode is correct and I'm not opening any level using '?game=[gamemode]'

[sonic lake]

@crystal ingot is your startup map set correctly? that may be different from the editor map. Usually the log files contain some indications regarding to which map is being opened.

[crystal ingot]

yes, it's the correct map. After some attempts, I think that MAYBE I've found the solution. I say maybe because I'm not sure at all if this was actually the solution or if it's the right one, but apparently it work.

Despite the fact that the map was being included in the build, doing this fixed the problem. It was weird, because someone tried it on Oculus and it was working, but not on Vive, and now it work... I really don't know, I'll just remain blissfully ignorant and be happy that it's (apparently) fixed.

But then I have another issue to which I would like to bring your attention to, gentlemen:

https://forums.unrealengine.com/community/general-discussion/1854309-need-help-flashing-meshes-when-teleporting

It's about Occlusion Culling. In the video that I've posted you will be able to see the problem and maybe suggest me an alternative that is not straight up disabling Occlusion Culling

[sonic lake]

@crystal ingot Looks more like some kind of Z-fighting to me. Does it do it also with a different mesh as floor? Or with a different material on the original mesh?

[crystal ingot]

Not sure, I can try. I'm assuming it's Occlusion Culling because if I disable it, then problem it's fixed. But Occlusion Culling it's a nice thing to have since we are in VR, so I would really prefer not to disable it.

But I'll test my luck and see if changing mesh and material yield the same results

[opaque adder]

Hey guys, I have replaced the hands in the Motion Controllers Pawn with two gun models. However I can't seem to get them lined up right compared to my real world controllers. Any tips on how to do this properly?

[crystal ingot]

based on how you describe the situation, I would say just move the static mesh slightly off the center until it feels right.

[real needle]

Hi, I´ve realized that bloom doesn´t work on mobile-VR (Quest), but I´d really like to add this to my game. Does anyone know of another method to fake some kind of glow with a shader (on a separate doubled and slightly bigger mesh) ?

[chrome elk]

Anyone have issues with VR preview being off center from what the headset is looking at? I thought I was going crazy so I added a cursor at the dead center of the HMD view and sure enough it's way off in VR preview:

anyway, it does this both in-editor and in a production build

[thin lion]

I tested out the sample default VR project and they worked fine. Then I make a new level and pawn, and new action bindings, but the new action bindings don't work

Hey guys, I am having a issue with movement in VR. When i try to grab but nothing is around my movement gets all messed up any ideas why?

I haven't made any changes to the default pickup/grab function

[compact kayak]

Hi everyone! 😃 Has anyone had any luck running a game in unlit mode on the Quest? Is it even possible? Thanks

[wheat holly]

I believe the preview on a monitor is based off 1 eye, so it would make sense in that case to be off centred. I'm not entirely sure how badly you need it to be centred exactly in the middle?

[chrome elk]

That @wheat holly , that's the conclusion I landed on as well. It's not the end of the world, I think it was more jarring because I swear it wasn't like that in earlier versions of UE4

[wheat holly]

Are you sure your pawn is having input? Have you tried binding it to a different button and just print a message to see if that works?

You can fix it, but that costs a ton of performance unfortunately.

[chrome elk]

and by 'that' I meant 'thanks.' Early morning I guess!

[wheat holly]

Haha no worries xD

In case you're curious, this is how you would do that. But since it's a complete different "camera" you're basically rendering another 30 / 60 or so frames on top of what the HMD is already rendering... So it's not worth it if you just want to fix it for being a bit off centre. https://docs.unrealengine.com/en-US/SharingAndReleasing/XRDevelopment/VR/DevelopVR/VRSpectatorScreen/index.html

Especially not when you've a bigger scene, then it's just really throwing away performance 😅

[wheat holly]

Are you sure that when you're in the VR preview your VR headset is selected as the audio device and not a different one, or that it at least sends the audio from your pc to your VR headset?

[wheat holly]

I don't have a quest my self, but your question seems a bit vague. Do you mean having a material that is unlit?

[tame stream]

I'm trying to get oculus mixed reality running for my game (rift s)... however i dont really know to activate it. is there anything more apart from this i need to do?

[thin lion]

@wheat holly My pawn does receive input, and I am trying to print to the screen. No luck

It seems like a major glitch

The default VR pawn works with print statements on the existing controls

But if I add new custom input mappings, none of the new mappings work. Even if I remove all the previous mappings, so I can be sure it's not a problem with consuming inputs

But keyboard mappings DO work, so the mapping are updated, and the pawn does receive input

It's so strange

[wheat holly]

Is it possible to share some screenshots of the code or blueprints and of the bindings?

[tired tree]

@thin lion steamvr correct?

your manifest wouldn't be generating correctly

[thin lion]

Yeah, SteamVR

What manifest file are you referring to?

@wheat holly I will come up with a simple re-producible example

[compact kayak]

Appreciate you replying @wheat holly. The PCVR version of the game runs in unlit mode. That means that it calls the console command "viewmode unlit" on beginplay and I've also added "r.ForceDebugViewModes=1" to the [/Script/Engine.RendererSettings] section in the DefaultEngine.ini. For some reason this doesn't work when I package it for the Quest. Any idea what could be going on?

[weary swallow]

I am having issues creating a VR interactable object that only translates and rotates on a single axis. I am using a linear physics joint on the BP that is like the BP_PickupCube but the movement is diffferent than expected

[tired tree]

@thin lion in project settings under steamvr they have some buttons for Regenerate manifest and regenerate bindings, hit the manifest and then the bindings

there is also the option to show those as a button at the top of the toolbar there

[sonic lake]

@weary swallow if you are doing it from scratch there are a number of tutorials on YouTube which can put you on the right track

My preferred approach is to track the hand but not link it directly to the interactable

In this way the interactable enforces its own movement and limits

[weary swallow]

@sonic lake So i found a reddit comment about creating an interface and then breaking apart the Xpos and Xrot, then putting them per frame to the pawn

[sonic lake]

I have a tutorial on a pushbutton, you can start with that one

[weary swallow]

@sonic lake that would be awesome thank you

[sonic lake]

It shows the basic approach: https://www.youtube.com/watch?v=l9hjb7kt854

[weary swallow]

@sonic lake thank you! really appreciate it!

[sonic lake]

You are welcome!

[sly elk]

Is the unreal engine VR template now a mobile project?

looking at the settings, it seems like a bunch of mobile stuff is configed

[weary swallow]

@sonic lake That tutorial is awesome! Thank you for pointing me in the right direction. I was able to get some results for that pretty quickly!

@sonic lake If I were to change the interaction from BeginOverlap to Grip button pressed would I have to make an interface in the motion controller BP with a branch for IsOverlappingComonent?

[sonic lake]

@weary swallow you can have the button check on overlap if the motion controller has the grip button checked before reacting to it

Check GripState if I remember properly

[hallow knoll]

@compact kayak For Quest I have Unlit materials on all of the models, I don't think viewmode wil work, and is a bit of a strange way to do it. Much better to just change all of the materials to be Unlit.

[trail shale]

I'm listening audio due to attenutation - the same sound plays in VR preview if I remove attenutation - somehow the VR system or steam audio changes the distances - I understand how the attenuation works but VR throws a wrench in it

[desert rivet]

I just had a friend test my VR project on his Vive Cosmos and he said none of the buttons on the controllers work. The motion controller move ok and he can see his hands, but no input from the sticks or buttons. Any thoughts on how to trouble shoot this? I personally have a oculus and a Index, which it works fine on

[desert rivet]

Ah, I just noticed the WMR plug-in which isn't loaded by default. If the Vive Comos is classed as WMR, then I think I found the problem

[outer hearth]

Hi guys. Anyone successfully deploy an AR app to an iPad or iPhone? How do I get started? Trying to build a configuration app in AR. Should I switch to Unity instead?

[sudden glade]

@outer hearth I think might be you can try with the default project about ar, it works on ipad& iphone, but it need arkit, a plugin inside

[little scaffold]

is 4.26 stable enough for AR projects on Iphone and Android or should I go with 4.25?

[celest basin]

Hey everyone, bit stuck, nagging everywhere till I can find someone who can help

I got this here VR Pawn and an ALSv4 Character

I want to use the ALSv4 dude as an IK body for the VR Pawn

But if I put him in the same place as the VR Pawn it kills him

Don't want to possess him because when I teleport I want him to run to the teleport point first then jump the VR pawn to it

[reef lily]

@celest basin You just need to make sure their collision volumes don't react to eachother then

Right now I guess both are set to Pawn, and Pawns collide with eachother

Dang... I spent like the whole of yesterday getting a Fade Screen to work in my UGameViewportClient, but now when I actually tried the project in my HMD it seems UGameViewportClient doesn't even run in VR.

None of the breakpoints trigger

[polar valve]

Are the Vive trackers suitable for enterprise use? For a turnkey system. Seems quite finnicky so far.

[gusty plume]

I'm building for Oculus Quest. I used the reccomended settings for the renderer but the build i'm getting is so aliased and the fps is too low. I'm not sure where or how to start for doing optimization. Is there a good source you can recommend?

[wheat holly]

Do you already have an entire scene, or just an "empty" one with perhaps a couple of things?

[polar valve]

Mobile MSAA on, Mobile HDR off, forward shading on,mobile multi-view on, instanced stereo on?

https://www.youtube.com/watch?v=JvMQUz0g_Tk

Hello 🙂 I have a question about building for the oculus quest 2. Video content (Media textures) sometimes don't work (after building), and if they don't work it's just a black material. Any ideas?

[weary swallow]

@sonic lake Thanks for the help on this! Now I just have to figure out a better fix for the physics because the ball behaves unexpectedly half the time

[sonic lake]

@weary swallow VR fussball, nice! 🙂

Come to the #legacy-physics channel to sort out the ball issues. Probably you need to turn on CCD or enable physics sub-stepping.

[opaque adder]

Hey does anyone know how to disable SteamVR Input and use the old input system? I'm using 4.25.4 and my games won't work with SteamVR Input

[languid narwhal]

So like i wanna make a vr game but when i go to Program Files(×86) > Epic games > launcher then i dont see the extra's folder?

[compact kayak]

My materials are all unlit, the difference is the bottom image is the default forward rendering passes and the top image is the Unlit viewmode/ignoring all lighting pass data. I can't get it to look like the top image in a packaged game for the Quest. Any suggestions?

[tired tree]

@opaque adder you can't

its built in with the new input setup

legacy input is gone

you need to remap to the steamvr action manifest now

[opaque adder]

@tired tree I'm having issues with the inputs not working in the packaged build. Not sure whats happening, but I cant progress at all until this has been solved. I have posted to the Valve Software Github page https://github.com/ValveSoftware/steamvr_unreal_plugin/issues/178

[tired tree]

@opaque adder is your config/steamvr directory packaging out?

also its fairly easy to load up the steam input overlay and check out what is actually bound and what isnt

[opaque adder]

Thats the wierd part. When I open the "Show bindings on controllers" menu everything is mapped right

this happens in the default Motion Controllers Map too

clean project

works in the editor but not in build

[tired tree]

when you open it in packaged?

[opaque adder]

yes

[tired tree]

yeah thats strange

[opaque adder]

I want to reset all locally saved input profiles in the SteamVR app, if I've accidentally messed something up there

[brittle crown]

Im trying to capture audio via a vive internal mic. I'm getting blank wave files. I'm having trouble finding any documentation on audio submixs

[ember pumice]

Can I use the steam VR plugin with my oculus quest?

I'm not sure what the plugin does

[maiden willow]

You would only want to use the Steam VR plugin if you will be using the Quest as PCVR. If you are developing a native Quest app you would not want to use it.

Trying to figure out the correct aspect and resolution for a VR hud. It's pretty dang hard. 😮

Especially when different HMDs have different resolutions and FOVs

And it depends on the depth at which you render the 3d widget

[wheat holly]

@reef lily I had to do that but for an asymmetrical game and then to be more specific the PC player UI, since you can't use widgets on the screen it self. I found a topic on the forums with someone who made some functions to get the width and height from the camera at a certain distance. It's C++ code though, not sure if you're using Blueprints. https://forums.unrealengine.com/development-discussion/vr-ar-development/1579732-how-to-measure-frustum-at-a-given-distance-from-camera

[reef lily]

@wheat holly Ah nice! I'll check it out

[reef lily]

@wheat holly thanks again, that was super helpful

https://imgur.com/jXJRSIv

[wheat holly]

Glad I could help :D

[reef lily]

An oddity is that you'd think that you should make the HUD at 4320x2160 for the Reverb G2, as that is the official resolution

but with that aspect ratio it stretches pretty properly to the sides but leaves top and bottom

So you need to stretch the vertical by around 1.5x for it to be the correct aspect ratio

so the HUD resolution should be like 4320x3240

[sly elk]

Did anything change in 4.26 with touchpad inputs? we get a hard crash on vive when clicking the touchpad now

and I think it has to do with code we had before to click inputs

[quiet swan]

@sly elk 4.26 broke VR for me, my body for VR doesnt work anymore in 4.26 like it did in 4.25, over all I heard 4.26 is the worst update for unreal, and it doesnt look good for VR moving forward, at least thats what they said on the unreal forums

[tired tree]

Whoever said that is too reactionary and flat wrong

[quiet swan]

I dont know I asked on the forums and it didnt seem like 4.26 was that good for VR, I know it broke my set up, maybe another update will fix it, me I have to stay on 4.25, I am not happy but what can I do

[sly elk]

We resolved out 4.26 input issues. Overally, VR has been minimally impacted for us

the touch click actions being removed were part of the issue

[gaunt pumice]

Anyone else having issues with the three dots loading screen in the oculus quest after installing an apk vom unreal?

Not sure why, but every time I have to delete some folders inside the UE project folder before packing to make it work...

[reef lily]

Anyone figured out a clever way to do interactive loading screens? Where the player can still look around and move about in a small area or something while a map is loading?

VRChat has one that displays tips while a map is downloading for example

[viscid moat]

I believe you just make a transition map

[reef lily]

I'm thinking level streaming should be great for this. But I'm not too keen on having the entire game in one persistent level

@viscid moat sure, but the game would stutter horribly while loading the new map on the main thread I reckon

If even playable at all

[viscid moat]

I mean you could technically put the player in the map they are supposed to be in, put a white box around them and fade them into it and do whatever you want in that box, then fade again when ready and hide the box.

[reef lily]

Yeah... maybe not a bad idea

I think I'll try something along those lines 🙂

[viscid moat]

If it works for you would love to see the result! GL

[wary thunder]

:triangular_flag_on_post: Grey flamE#2085 received strike 1. As a result, they were muted for 10 minutes.

[reef lily]

@viscid moat your method worked out pretty darn well! This is just a mockup of the actual implementation, everything placeholder and only fake loading with delays instead of streaming, but should work in theory!

[grand kiln]

does anyone have an good tutorial on how to make a physics based ik for vr in unreal engine?

[reef lily]

I wish.

Been watching Nimsony, @grand kiln ?

[grand kiln]

who?

[reef lily]

He's done a fair number of videos of physics based IK for Unity

But I don't know of anyone who's achieved it in UE4

[grand kiln]

oh )=

[viscid moat]

Awesome! I have to do this myself, so good to know thanks

Oh wow it didn’t load the gif at first that looks amazing!

[reef lily]

I just spawned a hollow sphere with a collision box floor at (0,0,-50000) in the BeginPlay of the new map, SetActorLocation the player there, then sublevel with all the maps assets would begin streaming, then once that's done, tp player to the PlayerStart in the map and get rid of the loading sphere.

along with some PlayerCameraManager->FadeScreen and delays

Preferably I'd like the loading sphere to be at the PlayerStart and then just dissolve once done, rather than fade to black and fade in again, but I don't yet know a way to make that happen without the map floor and other close objects poking through the sphere

[sonic lake]

@reef lily consider that you do not need the loading pawn to be the same as the playing pawn. You can create a dedicated one for the loading phase (without the possibility to move or collision handling for example) and then switch to the complete playing pawn once the level has loaded.

In this way there is a lot you can simplify in the process.

[tame stream]

i'm currently trying to use the oculus mixed reality capture. when i start my game using the command line parameter -mixedreality however, the application crashes with a fatal error. here's the log:

has someone managed to run this successfully? or does someone know what i'm doing wrong...

[reef lily]

@sonic lake Good point. I probably want the main menu avatar to be different from the in-game avatar (like just a pair of flying hands or something). Though the main point of all this loading shenanigans is that I want the transition to be as seamless as possible (especially between game levels). So keeping the pawn then and just toggling if locomotion is allowed etc would be ideal.

[sonic lake]

If you fade the camera to black then posses the new pawn and finally fade back the transition with be totally seamless for the user. Just something to keep in mind.

[sly elk]

We are seeing weird stuff with the cursor being offset in desktop play modes. Might be related

[sly elk]

Has anyone else ever had issues getting unreal to generate steamVR input jsons with all the inputs in them? Most of them generate correctly but vive cosmos is essentially empty:

We don't have a vive cosmos and are trying to set these up kind of blind. I can't edit them in the steamVR tool without the controllers

[reef lily]

Anyone know if there's a place to get hold of the mesh representations for various VR controllers? Can't find the ones for the HP Reverb G1 and G2 controllers

And the plugin for Oculus VR only had static meshes for the quest controllers rather than skeletal meshes

Also can't find meshes for the Knuckles 😛

Hmm, found a lot of controllers in .obj in the SteamVR folder. They're cut up though, so like buttons and triggers are their own objs. Have to recombine them into skeletal meshes I suppose

[celest basin]

Still trying to move my VR pawn inside a mannequin after it ran to a teleport but UE4 just won't let me

It's really really annoying

Is there "Just effing go where I effing told you to go you effing ef" node?

[sonic lake]

@celest basin can you share a bit more about what you tried and what is happening instead? Do you get any error? Unreal doesn't do what I want is not enough information to try helping you out...

[celest basin]

I managed to smash through that

I have to do lots of turning collision on and off

[sonic lake]

@reef lily usually you can find them in the content of the various plugins, but most of them are just static meshes. For Oculus you can find animated ones in the demo projects on their Github.

@celest basin good to hear! Yes, collisions may interfere with spawning and teleporting.

[celest basin]

If I want to see the navmesh in VR, is that just a command line thing?

[sonic lake]

P in the editor

you should see a green floor

[celest basin]

yah, that work in editor

can you see it in VR preview too?

[sonic lake]

good question, I never had that need.

there may be a console command, let me check

[celest basin]

Cos I got it so the dude runs to teleport, when he get's there I teleport there too

But the navmesh is terrible, so there's lots of places he can't get to

[sonic lake]

Try with Execute Console Command "show navigation"

[celest basin]

that's via nose typing yah?

[sonic lake]

That with a Blueprint Node called Execute Console Command

[celest basin]

ooh 🙂

[sonic lake]

which you add to Begin Play

so your nose is safe 😉

[celest basin]

Ok, I make video, cos it's sort of cool even if it's still pretty clunky

cos dude has ik hands too (when not moving)

[sonic lake]

sure, show it

[celest basin]

which is going to be a whole new bucket of pain to fine tune

[sonic lake]

You need IK with constraints to do it properly

[celest basin]

yah, that part is actually surprisingly easy

that'll be a trickier design issue trying to calibrate the mannequins joint positions with different players

[sonic lake]

I wish I knew upper body IK was so easy before we worked on a dedicated plugin for it... 😉

[celest basin]

heh heh

hey, what's the best way to record vr preview with OBS?

Display Capture?

[sonic lake]

Dunno. I don't use OBS.

[celest basin]

Aight

This is pretty rough (it's my first time recording VR)

But you can see what I'm trying to do...

c'mon youtube

https://www.youtube.com/watch?v=VqUruI8H-ig

I think with a bit of tweaking it might a playable form of navigation

[tired tree]

@celest basin yeah I have that as an exampled movement mode, and so far no-one really has used it in their projects

VRChat uses it as their sickness reducing mode and its fairly common in there at least

[celest basin]

yah I can't handle sliding 🙂

But I played (way too much) skyrim in teleport mode and... well, you're basically the flash

I figure this is the best of both worlds

You'll be happy to know I finally got my head around room space VR @tired tree 😛

My brain was stuck in seated VR thinking

[reef lily]

Has anyone tried locomotion where it's like free movement but also teleportation? So you press the stick forward, and every, oh lets say 1-2 seconds you tp forward an appropriate amount

And if you let go of forward after holding it 1/2 sec it just teleports you 1/2 of the way

[tired tree]

@reef lily pavlov has something kind of like that

[celest basin]

hmmm interesting...

[tired tree]

its not the best

[celest basin]

maybe have like a radial timer on the teleport?

further is longer etc

[tired tree]

in the end a lot of people are going to have more issues with disorienting blinks than not

some people actually can't handle teleporting due to it confusing their spacial recognition

"some"

[celest basin]

lol

that remind me of a lady I used to work with

[reef lily]

Yeah, I'm fine with sliding unless it's done poorly with lots of up and down or acceleration

[celest basin]

she tried to say we couldn't use any red or green cos of colorblind people

[reef lily]

In what kind of work?

[celest basin]

visualizations

[reef lily]

Could be a valid constraint if it's important, like government, stuff

[celest basin]

trick is to have multiple indicators

so you can still use red and green

as long as there's also something indicating diff (i.e icons)

<something else>

[tired tree]

more options is always better

though dash teleport is generally preferred over staccato blinks

[celest basin]

What's your opinion on snap turning in room space?

[tired tree]

nessecary for many

[reef lily]

Funnily enough something that... while it doesn't nauseate me, it really really drops the immersion factor, is edge fading

[tired tree]

though a lot prefer smooth, offer both, for some reason smooth turn is the only VR movement that i can't handle

[reef lily]

Yeah, snap turning is mandatory if you use Oculus Rift or Vive or anything with basestations

[celest basin]

ah, yeah

I'm spoilt, I got a brand new quest 2

[reef lily]

Smooth turn is as MordenTral described in the VRE demo, barf machine 😛

[celest basin]

Anyways, ta for the advice and patience 🙂

I'm bailing...

[reef lily]

I'm trying to make sense of making good multidevice-capbale input mapping. It shouldn't be this complicated. Reading up on OpenXR right now and how it works with UE4, but still clueless as to whether it's ready for use yet and if I can use it in conjunction with SteamVR Bindings and what will happen with my Action and Axis bindings etc... so many question marks in this area.

[tired tree]

steamvr copied the openXR input methodology

[reef lily]

I just figured I'd set up my action bindings correctly and that'd make it work with multiple forms of controllers, so I don't understand the need for OpenXR and all that...

[tired tree]

they work hand in hand

when the engine switches to openxr fully it will "mostly" work as is

[reef lily]

So I don't need the OpenXR plugin then? Or does it handle more things than just the input?

[tired tree]

the steamvrinput module has some auto generation quirks, so a lot of the time you will need to finish mappings in the steamvr overlay, but that won't be any different in full openXR

openXR is going to be the engines default soon

and you should totally use it (when finished and stable)

bit early still though

[reef lily]

Just wish there was some documentation on all this outside of hour long Epic youtube videos

[tired tree]

well mostly right now its just putting different controller keys in actions

steamvr has such complex bindings that you just need to finalize them in overlay

can't imagine that being any different down the line, so worth getting used too

[reef lily]

Oh wow

"Epic will exclusively support OpenXR with Unreal Engine 5 in the official download version. The native interfaces like Oculus, SteamVR, Hololens etc. will be available for a while, but only via self-compliant versions, not in the official version. Epic explicitly recommends OpenXR as an interface."

[tired tree]

yeah

thankfully

finally happening

[reef lily]

Always feels like I'm working with tech that is gonna be finished a month from now 😛 Same with replicated physics

Perpetually one more month

[tired tree]

what part of replicated physics?

its generally stable in engine for most uses

though the chaos version is better

[reef lily]

Well that's the thing, it feels like it's on the cusp of being 1.0. You can technically use it right now with the plugin, but there's only sparse documentation and examples and not super battle-tested yet

Same with Chaos

So you're on the bleeding edge if you use it

[tired tree]

chaos itself isn't ready

but engine default physics replication is functional for most uses

and recently was improved

[sonic lake]

Chaos is a bit a case on its own, if you think about it replacing an established physics engine is not an easy task, but eventually it will get there.

Yes, still few gaps but it is going in the right direction.

[tired tree]

chaos doesn't even change the core replication, its the same system, they added a sync system on top of it for easier directed movement and force syncing

also though, having fixed tick is going to help a lot

[reef lily]

@sonic lake Definitely. I just wish they'd focus more on those things over things like live video, keying etc. I may be wrong or biased but it feels like those features only benefit a tiny subset of users, while things like Chaos would benefit many more

Though maybe that part of the market pays more, I don't know

[sonic lake]

@tired tree did you also look into the NetworkPrediction plugin?

@reef lily in general the overall engine documentation may benefit from some dedication. I believe they have hired extra people to take care of it recently.

[reef lily]

"Oculus OpenXR" plugin. Uhm. Isn't this just the sort of thing that OpenXR is meant to combat?

[sonic lake]

That should be meant as the OpenXR implementation on the Oculus side.

So you can "talk" to an Oculus device using OpenXR, while internally they take care of bridging OpenXR to the Oculus API.

[reef lily]

Yeah that is what confuses me. I thought that you only would need to add the OpenXR plugin, and then it would have all the functions built-in to speak to devices from all manufacturers. So working in UE4 I would just have to do OpenXR->IsStickPressed() for example and it would convert that into checking that for an Oculus controller if one was active

But I'll look into it more until I understand!

I have like 10 tabs with the stuff, so the info is out there. Just have to find and compile it. 😛

[sonic lake]

Yes that is the case. But it is the same with other standards like Bluetooth. Internally each device works differently, but from the outside you can talk to them with a standard language.

The device manufacturer guarantees that the device "talks" OpenXR and you, as a developer, take advantage of it.

[tired tree]

@sonic lake yeah that is what i was talking about

also pretty sure the oculus openxr plugin is temp

[sonic lake]

Yes eventually any VR device specific plugin should disappear from the engine.

[spare crown]

Hey guys, i'm having a problem with multiplayer spawn. I'm trying to have 2 players spawn on 2 playerstart. When i use a defaultPawn or a character everything is fine but as soon as i set my pawn to be a vr character from VR expansion plugin, my two players start to randomly spawn on the same playerStart. I guess i'm missing something. Does anyone have an idea ?

[brittle crown]

@spare crown have you looked at the Collab View template?

Players spawn at separate locations, I've been using it as a jumping off point for some really entry level VR stuff - that's the most help I can really provide unfortunately.

[tired tree]

@spare crown you didn't port the example game mode over did you?

also that may be the collision check

[spare crown]

@brittle crown i will look it up thanks !

@tired tree by "example game mode", do you mean the game mode from your VRPluginExample project ?

[tired tree]

yeah, the player controller from that selects a random player start

but if you didn't, then its spawn collision not firing off since the collision is wherever the roomscale is

[spare crown]

@tired tree I tried putting a second playerstart in your VRPluginExample project and spawning 2 players and they sometime spawn at the same location

[tired tree]

yeah its entirely random in there

i don't bother to check proximity

[spare crown]

oh ok

[tired tree]

it checks if it should be an FPS pawn or a vr one

spawns the player, and selects a random start

its not a game so it doesn't matter in there

[spare crown]

So i should use the spawn collision to change the targeted playerstart ?

[spare crown]

That sounded like it was already implemented but i can't find where. Am i misunderstanding ?

[tired tree]

in the player controller

[spare crown]

i can see the random start in the player controller but no spawn collision handling and i feel like that's what you said before by saying "yeah its entirely random in there, i don't bother to check proximity".
But then i don't understand how using that player controller would help me avoiding a double spawn on a single player start which is what i understood when you said "but if you didn't, then its spawn collision not firing off since the collision is wherever the roomscale is".

@spare crown you can literally just capsule overlap check at the start

that is what player starts do anyway, but they hard code off of the actor origination

i'll just pm you

[brittle crown]

Hey my main menu is taking up the whole screen when I'm using VR

The level it's sitting in is completely empty. I want to use it to enter in a Username and then enter the VR enviroment, the explanation I keep seeing is to pull the widget away from the pawn camera - but the menu still appears the same via the headset but looks normal in the viewport

[maiden willow]

are you spawning the UI attached to the VR Pawn? You may need to adjust there rather than the editor view

[brittle crown]

hmmmm

The widget moves with the headset

so that it's always in the same place

[maiden willow]

Try increasing the 80 value to like 500

or more if needed

[brittle crown]

Yeah the part of the widget stays stuck

but its weird It's like fixed to the screen moving around the menu remains in place

I'm using the Collab Viewer Template as my base

[maiden willow]

It doesn't push the widget out if you change the value on the Place Component in front of VR?

[brittle crown]

@maiden willow Nope

[latent ferry]

have any of you guys got any favourite examples of how to handle players moving their HMD through in game geometry like walls? Not sure what the best approach is?

[tribal lintel]

Check out some gameplay of budget cuts, and half life alyx. Half life they put sphere over the players head, and use a material to show the direction you entered the wall in. budget cuts 1 has a much simpler system, both have been great approaches, HLA is probably best, you can then press the movement/teleport stick to snap back to where you were before you entered the wall. IMO whatever you do, don't enable collision on the HMD so that putting your face into a wall pushes you back, I absolutely hate that

Also, it looks like there is no VR C++ template for 4.26, correct?

[viscid moat]

Yes, that is correct.

[tribal lintel]

Cheers!

[latent ferry]

@tribal lintel Cheers I like the sphere Idea but found the orange of HL Alyx a bit much. I think I'll try the head sphere with black and the exit direction prompt + a bit of fade in when you are getting close to the geometry. Thanks again, just mentioning the head sphere has put me on the right path I think.

[tired tree]

@tribal lintel the push back is getting to be the most common method now, and you can still darken / blur or point out the vector to get away from it with

[ember pumice]

What I did was

When your head is inside a wall

Theres a sphere that shows the direction you came from

If you go the opposite direction the sphere goes smaller until it just prompts you to teleport back to your location

[celest basin]

Aight

I've got my character dude running around in VR now, but the navmesh stuff seems really flaky

i.e. I got this corridor leading down to the bridge on my ship

all hooks up

but when I try to send my dude to points on it, sometimes he'll just run down it normal, other times (randomly) he'll try to run the other way out of the ship : /

here's the navmesh with the ship hidden:

Is this normal behaviour for navmesh? Can you tell it to take the shortest path somehow?

Also, is there a better channel I should be asking this in? I just assumed cos I'm doing it in VR

[polar valve]

@celest basin It's possible the navmesh is too thin in places so your ai can't reach it. Probably more relevant to the ai or blueprint channel.

[celest basin]

ooh, AI, didn't see that 🙂

[quick salmon]

Hi all can anyone recommend VR videos or references to trigger objects when looking at them with HMD?

I’m stuck

And I need help

[celest basin]

phrase you're looking for is "gaze control"

youtube's got a bunch

[polar valve]

Long shot but can anyone confirm if delta time works on the Pico Neo 2? Using 4.25 and it's just fixed to 13.8ms regardless of FPS. Not using framerate smoothing or fixed framerate. Does work on the Quest.

[quick salmon]

Nice thank you I will look into it

[celest basin]

that is effectively what gazing is 😉

https://giphy.com/gifs/images-monkey-drums-Xvz7fb8rEWZtS

[obtuse spruce]

edit: I am fake news

@quick salmon The VRExpansionPlugin has a component for gaze interaction, if ya don’t want to make it from scratch. It was bugged when I used it ~1yr ago, which I patched over w/ BP code — don’t know if that was ever fixed

[tired tree]

@obtuse spruce no it doesn't

might be confusing a different package

[obtuse spruce]

@tired tree And just who are you to correct me on this? 😉

Must have been thinking of the Runeberg VR plugin

[tired tree]

@obtuse spruce the author of the VRExpansionPlugin?

oh sorry, winky face ;p

long day

[idle osprey]

Does anyone with Epic 4.26.1 on Win64 have time to test something simple for me? I'm on a Mac right now. In 4.26.0, I was having trouble with the vanilla VR Blueprint template compiling. It was choking in the BP_MotionController with the SteamVR Chaperone and GetBounds. I just want to know if that basic template compiles now. Or if this is an OSX issue they introduced in the 4.26 series.

[obtuse spruce]

Haha, no worries m8 👌🏻

[untold knoll]

sorry I am kinda late for this one but I have been facing thee exact same problem. I don't want to do level streaming. i am trying to understand what you did here. what exactly are you fading out? the material of the box?

[hoary talon]

Anyone ever done a grab and hold onto a physics actor and have it pull you wherever its going? be it via physics or other?

[tired tree]

same logic as climbing

if you go the non physics route

[urban igloo]

@idle osprey It works fine for me

on Windows

[quick salmon]

So guys I've been testing the gaze interaction which worked for doing a rotation of an object after 5 seconds, what i'm trying to do is to display a widget after with an image, and I'm inside the VRPawn trying to delay between rotating the object and spawning the image based widget, any ideas how can I get a delay node?

The node needs to be placed where the white small comment is

if I connect the two functions, the time and the image gets displayed together

[quick salmon]

guys any ideas please?

[polar valve]

Create a custom event in your pawn and put the delay and the rest of the code there? @quick salmon

[sonic lake]

@quick salmon or use a timer

[quick salmon]

so do I collapse the code and make a custom event in my event graph and connected to the collapsed function with a delay node?

[quick salmon]

set a timer between the variable and the isvalid node

?

also when i use set timer, I get many of them, do you know whats the exact name of the node? or under which category ?

[polar valve]

yes

[polar valve]

Is there a specific reason you'd use a timer instead of a delay or is it just preference?

[polar valve]

I assume he means this

[sonic lake]

https://docs.unrealengine.com/en-US/InteractiveExperiences/UseTimers/index.html

With a timer you have much more control of the flow. There may be cases in which the player starts and action then wants to stop it. A Delay won't allow you that. A Timer can always be reset.

Especially with gaze selection/interaction you have to give the player some time to confirm their choice. It should not be immediate.

Typically it goes like this:

1. overlap detected with the gaze interaction system --> start timer
2. overlap ends --> reset the timer
3. timer completes --> run interaction code and reset the timer

[polar valve]

Right, I didn't really pay attention to the context. If you need to cancel it then it should be a timer. I personally prefer to use delays for simple scenarios when I can. For clarity

[sonic lake]

Agreed. Also Delay has not equivalent in C++ while Timers have, so when you try to port your BP code to C++ you have to solve that anyway.

[quick salmon]

Thank you Macro I will look into the link

[quick salmon]

Thank you Joost I will check

[polar valve]

You can also use this if you don't want to use a custom event. But I'm not a big fan of manually typing in a function name.

[quick salmon]

I tried this but didnt work 😦

[polar valve]

I'll show you an example

[quick salmon]

Please

[idle osprey]

Thanks. Looks like it's just OSX. 😞

[quick salmon]

The first one is inside the function and the second one is inside the eventgraph?

[polar valve]

yep

[quick salmon]

Am I doing it correctly? its not doing anything in the scene

Even this is not working

[polar valve]

What event are you calling?

You also shouldn't give functions and custom events the same name btw

Also I'd try to make your function names more descriptive

[quick salmon]

So I am trying to delay the good sign from the loading bar that executes rotation

this is the code that is responsible for you to gaze on the object, get the loading bar

I wanted to add the widget afterwards
[4:44 PM]
but they are presenting together and when they are gone they are gone together

[tired tree]

@sonic lake one caveat with timers is that if the trigger time is too fast when compared to framerate, it can trigger multiple times in one "frame"

I always bring that up when talking to people about timers vs tick/delay/timelines

lots of people read the fluff about tick and throw low duration timers on everything and end up screwing their logic

[sonic lake]

@tired tree Fair point. The max resolution of a timer is capped by Delta Time anyway. I don't think it matters in this case since I understand the time span is in the order of 2-3 seconds.

[tired tree]

yeah, just see a lot of newer people try and timer to 100htz or something when hitting 60 fps, then getting multiple triggers

[sonic lake]

that would be physics sub-stepping for the poor man (which doesn't work anyway) 😉

[keen oasis]

Looking for guidance on how to use setup an Oculus in UE4 without using Touch Controllers. Struggling to find anything online that doesn't rely on them.

[maiden willow]

https://www.youtube.com/playlist?list=PLbgD2Tk2QUnkYVdDN-EMSiinyKpWXRpIR

[urban igloo]

If I use CollabViewer and include a planar reflection, it seems "owner no see" is not applied to the reflection. which means I see filckering reflection on the name plate. Anyone seen this?

I don't even want a solution. Just tell me I'm not crazy.

[keen oasis]

Thanks this looks v cool and I’ll check it out in the future. For this project though I only have access to an oculus rift, one sensor, a remote and Xbox controller. Looking to purchase touch controllers soon but for now I just want to setup a camera for the headset without controllers

[maiden willow]

Ahh I apoloize I assumed when you said no Touch Controllers that you were talking about hand tracking. You should be able to map the Xbox controller just as you would any other project though.

[long citrus]

Can I have more than one actionset in steamvr input plugin ? I know I can add more by editing manifest but it doesn't seems to be handled by plugin.

[tired tree]

@long citrus no it doesn't support multiple action sets or switching between them

[ember pumice]

I'm developing for the oculus quest and I've enabled forward rendering

And so I have mobile hdr disabled.
Is there a way I can have post process materials using forward rendering?

Because they aren't working

[covert ferry]

Hi guys,
I want to record some mixed reality footage of my app.
Is this something I have to enable in unreal engine ?

If so, how ?

[keen oasis]

No worries! Ok I’ll keep searching around thanks!

[hushed nova]

Hey, does DrawDebugString not work properly in VR? It always displays the message some place other than what I specified and with the wrong duration

[upbeat marsh]

Hi all,
Anyone knows how can I switch between hand and controller meshes?
The auto switch for quest hands/touch controllers works great, but the controllers are empty (don't get the mesh that the oculus hands do).
How can I make the meshes appear on the controllers as well?

[upbeat marsh]

@ember pumice
PP doesn't have work in Forward, as most.
There's a good table with detailed info: "Supported Rendering Features | Unreal Engine Documentation" https://docs.unrealengine.com/en-US/RenderingAndGraphics/SupportedRenderingFeatures/index.html

[ember pumice]

This is so sad

Thank you

[long citrus]

That's very sad and annoying. Thanks for answer.

[reef lily]

Sorry for being late too, I never saw a mention! :S
I am in fact using level streaming, but it's not a persistent level from the main menu to the game map. I have each game map be a completely empty persistent game map, apart from the loading box/sphere far below 0 on the z axis. That map will load instantly from the main menu with a normal Open command. Then while the player is in the box I stream in the sub level for the map with all the content. Once that's done I tp him to the normal start position for the map.

As for the fades, I simply use GetPlayerCameraManager->StartCameraFade

[reef lily]

@tired tree I'm still trying to figure out the right way to set up input mappings that will be future proof with OpenXR (or at least easily portable), and I'm looking through your VR Expansion Plugin, but there's so many things that are commented out or in a TODO state, and I know this field is evolving so fast right now that things from just a few months ago can be terribly outdated, so I was wondering if you think it's still a good idea to use your plugin example as a guide for how to set up the input or if there's any better way now?

I still can't find a good definitive guide for how input should be set up for the OpenXR plugin

The Oculus Connect talks etc I saw regarding it and UE are outdated and have a now non-existing preferences submenu and use actionbindings "that/look/like/this", which I think now is something they are trying to move away from?

[tired tree]

@reef lily I don't handle input anymore really since the engine ported to the openXR methodology, you should be pretty safe in just using the engine itself as of 4.25+. I originally handled custom per controller mapping to prep people for OpenXR but now that the engine has per controller bindings I commented that code out (left for reference for now).

I assume that is what you meant for the commented out code, there isn't much commented in the plugin otherwise.

I still have some controller realignment code in there, but when OpenXR is standard, they use a palm origination for the default tracking that should be controller agnostic, so that won't be required anymore.

[viscid moat]

Oh god I really hope they do that. I’m tired of having custom offsets.

[brittle crown]

So I'm trying to set up an audio capture component that responds to vive trigger inputs, the trigger input actions I have on my Pawn work - but my audio capture BP doesn't seem to recognize them. If I set audio capture to start and stop using the spacebar its fine though.

[tired tree]

@viscid moat its already done when running openXR

everyone is going to have to refactor their hand setups

[ember pumice]

Are you saying if I map the inputs to my own controller xr will handle remapping inputs to every other controller?

[tired tree]

you need to put the seperate buttons down for each controller

and for steamvr at least, some effort is going to have to be made cleaning up the auto bindings due to the complexity of options

[viscid moat]

When is it expected that OpenXR will be full released for UE4 to start doing such updates? I heard it's still not quite ready.

[tired tree]

well its "functional" right now

in 4.26

but considered default is ue5

[opal compass]

How do I get openXR working in my project?

I got it booted up and it is rendering my sight onto the screen

but not into the HMD

[tribal lintel]

Sorry for the ping, but my searches in this discord brought me here. If you were offering to share your C++ code, I would really love to see your implementation for reference, as I am currently in this same boat, and had a little different approach but yours makes much more sense. If not no worrries. Cheers!

[nimble edge]

I have the same issue. When using OpenXR the spectator screen pulls up but the HMD stays black. I'd love to know how to get this working.

[tired tree]

with oculus right? they should have fixed that in 4.26.1

[opal compass]

I don't even know how to get SteamVR set up

can you help me out a bit?

[sudden lotus]

In 4.25 are you unable to pick a an object that you dropped if it has a scene component as it’s root component?

[ember pumice]

Hello, I need some advice.

• I have an Oculus Quest and I've been fiddling around developing as a hobby for some time.
• I have just got a job as a VR developer/programmer and I'm looking to buy myself a budget friendly/mid tier headset that won't need all the hassle the oculus quest needs.

I've been looking at the HTC Vive and the Oculus Rift S, which seems to have a reasonable price.
What do you guys think?

[polar valve]

Rift S is alright but it's pretty annoying if you have to take it off and put it on often (which is the case when you're developing for VR). I'd consider a Quest 2.

Don't really see any reason to buy a Vive anymore.

[sonic lake]

@ember pumice you can use the Quest with Oculus Link, basically it acts like the Rift S (which is being discontinued btw)

[ember pumice]

My oculus quest always has connection problems, I guess that's special to my device?

Also I would rather have something with less screen door effect

[short laurel]

Ive got a Quest 2 and Valve Index... Both are pretty awesome. Quest 2 works great - untethered is really sweet. I am really impressed with some of the native titles. The Wireless Virtual Desktop works well too. That being said, for PC VR gaming I still prefer the Index. It has higher refresh rate and is more comfortable. The Knuckles are amazing. Overall, both work great for UE development. Quest 2 is definitely the better value for your money.

[ember pumice]

I want to get the index once I have the spare money haha

Thanks everyone for the help

[cosmic shoal]

the quest2 has almost no screendoor

What I like about the vive is the robustness of it all, playspace is hardly ever lost, the tracking still the best and they seem less fragile

[ember pumice]

I realized I can't find any vive with a good price though

[covert ferry]

Has anyone here set their project up for mixed reality capture before that can advise me on how I should do it ?

[winged ridge]

Hi I’m new to development. Anyways my Entitlement passes but guardian isn’t showing as configured in unreal engine. I’m using an oculus quest 2 with link and have configured my guardian in the app but nothing seems to be working. Any ideas?

Essentially I want the quest 2 to act like a rift via link cable but can’t seem to get it working with guardian configuration

[nimble edge]

I love developing with my Rift S. I removed the entire Halo band so it's easy to simply hold it up to my face with one hand.
The Reverb G2 is a good headset. The resolution is best I've used, but the facial interface is a little too small/tight for my glasses.
The Index is my go-to for actual use, still. The frame rate and wide FOV do a lot for my comfort.

[ember pumice]

Haha I do that too but I haven't took out the strap

Does the rift s have any advantage over the quest 2?

[nimble edge]

I haven't used the Quest 2, I've moved away from FB products.

But the idea of a little USB C connector seems like a failure point.

[frail hemlock]

Anyone here with ARKit experience? I'm having issues with how the SetAlignmentDeltaTransform works and could use some help understanding it.

[marble junco]

After painstakingly porting an AR Project line by line from 4.22 to 4.26 because it didn't start up in 4.26 (it actually did, but defaulted to a black screen and an error "GetAndOrCreateGraphicsPipelineState RenderTarget check failed with: 185") and after some 40h of work I was left with the conclusion that it wasn't actually a problem with my code, but rather with the Pawn used. Well okay.. Time wasted.. But what I don't get is.. why? They are the same. Every single setting and component are identical, they use the same Pawn class as parent class, they are placed in the same plugin folder, yet my Pawn from 4.22 does not work while a newly (in 4.26) created pawn does work. Does anyone have any idea on what happend here so I don't run into this kind of thing again?

[tribal lintel]

I'm having trouble finding if unreal supports Vive Cosmos controllers. the cosmos controller has a joystick instead of a trackpad, but in the input there is only options for trackpad under the vive category. I have a different headset so I can't test this, does anyone with a cosmos know if the vive trackpad binding will work with the cosmos joystick?

[proper anvil]

hey, how's it going guys?
I keep getting d3d errors using my Oculus headset, even if I disconnect my 2nd monitor. I remember there is a cvar or a config file setting, which I can use to give more time for the GPU to respond, to prevent crashes, but I don't remember the name of it.
Tried setting rhi to dx11, and followed steps from here too. https://docs.unrealengine.com/en-US/SharingAndReleasing/XRDevelopment/VR/DevelopVR/ContentSetup/index.html

[humble spoke]

Are there any easy solutions for Locomotion + Roomscale? Basically I want the functionality of a "Character" class, but when you do this, your can move around in real life which naturally brings you outside the capsule making it's collision useless.

[reef lily]

@humble spoke Not that I'm aware of. That kind of problem/exploit is something that a lot of VR games have, and just something that you have to decide how to best tackle for your game

If it's a singleplayer game, who cares, really. Let the users exploit if they want to

Or you can fade the view if they poke their head through a wall etc

Or shove them back in worst case, but that can cause nausea

[wheat holly]

Tons of games have that fixed on a horizontal level though.

As in, when you collide with a wall you get indeed for example pushed back.

[reef lily]

HL: Alyx doesn't ever shove you unless you move the thumbstick

You can walk right through walls otherwise

[wheat holly]

However you are definitely going to need to be creative when it comes down to height, some games snap you into a certain height. Others try to do all kind of crazy stuff to get you back, Budget Cuts for example changes your vision with all kind of different colours on different objects, which indicates you should not stick your head through the roof xD

[reef lily]

If it's roomscale, I think the height is not an issue. It will always reset to the users real height (if it's configured correctly in the Oculus/Steam software)
