And that's exactly the problem, what if the person playing is taller than for example a door in their way or what about a vent you're crawling through. People tend to stick their heads through the ceiling, some games don't care if you do that. For other games it might matter more 🙂

Ah true

#

Damn I hate developing for VR. I just can't deal with all these vendor specific software things running in the background Windows Mixed Reality sucks big time. SteamVR sucks moderately. Oculus sucks slightly less but still enough.

#

All these bindings but no, the player controller just doesn't respond to them.

#

Also, I still don't know which one to pick between HP Mixed Reality and Mixed Reality

#

Mixed Reality worked before when HP didn't, but only HP had a Grip Axis while MR only had "Grip"

and MR didn't have the face buttons either...

Hey, does someone know how to update the Azure Spatial Anchors SDK? I was getting this "You're receiving this email because you currently use a version of Azure Spatial Anchors that will become unsupported on 3 February 2021." before and in fact it doesn't work anymore for me.

Has anyone managed to make a multi-player game for Oculus Quest 2 where two people can play in the same room and not run into each other?

reef lily
#

@tribal lintel Thanks. I'm already naming my thumbstick axii with _X and _Y, and also using the HP plugin. (I realize now that the old G1 controllers actually never had face buttons, I guess that's why non HP WMR didn't have those mappings)

#

@delicate phoenix it's one solution, but in VR, with every solution there's a downside. In this case, tall players would feel like their feet were in the floor, and short players would feel like walking in the air and wouldn't be able to reach items on the floor

Very interesting! I'm not familiar with inside out tracking so I wouldn't know how you would set both players initial world locations and maintain their accuracy, but I do know quest 2 has bluetooth 5.0 which has around a 130 foot range, bluetooth can proximity check between 2 devices. I'd be surprised oculus didn't offer some kind of API that let's you interface with it's bluetooth.

Or maybe have the each player set a real marker down like tape on the floor, then have them stand on it to calibrate their location and start the game from there

or you could do something absolutely wacky like use the oculus cameras (from said API) to read QR codes that the players print out and tape to their shirts or something, if I had more time I'd love to go down this rabbit hole (I don't have an un-tethered headset though). Sorry if this is all useless nonsense!

I'm trying to decide which engine version to use for my project, I'm going to use SteamVR and I will be developing on the oculus quest 2.

#

My options are the regular ue4 26 and the ue4 oculus branch

#

Does using the oculus branch have any advantages for a pcvr game?

#

For example would the Fixed Foveated Rendering work?

clever iron
#

Maybe one of you know. I packaged my server for a build with Oculus OSS. When I run my build on my local machine it works, I get
LogOnline: Display: Oculus: FOnlineSubsystemOculus::InitWithWindowsPlatform() LogOnline: OSS: TryLoadSubsystemAndSetDefault: Loaded subsystem for module [Oculus]

When I run the build on my windows server I get

LogOnline: Display: Oculus: FOnlineSubsystemOculus::InitWithWindowsPlatform() LogOnline: Warning: Oculus: Failed to initialize the Oculus Platform SDK! Failure code: -5

And it's literally the same build. Aren't all dependencies packaged into the pak?

clever iron
#

Failure -5 is "ovrPlatformInitialize_UnableToVerify." Really hopin there's someone with Oculus OSS experience who knows lmao

#

Did you ever solve this?

does 4.26 "un-deprecate" some BP nodes that 4.25 had killed off or am I mistaken?

I'm wondering if Oculus App lab would become available for Rift developers at some point ?!
kind of disappointing how they're ignoring us 😦

wheat holly
#

Do we really need it though? You can already really easily run any game that supports the rift by having a download to the game. It would be nice to have it yes, as it's a bit more official. But it definitely didn't require third party software like the Quest did need to make it accessible for most users (intentionally leaving away the Oculus Link Cable here, as it was all about directly playing on your headset).

In that case it would definitely be nice yeah, I understand your feeling though.

Hi! Does anyone have a tutorial or example on how I can make pick up items like in boneworks or alyx?

median idol
# ember pumice For example would the Fixed Foveated Rendering work?

Hi @ember pumice the Oculus branch has the most up to date version of the Oculus SDK which is helpful if you want to use the latest Oculus features. However it always uses a somehow dated version of UE and if you use it from the branch you will always have to maintain it updated by yourself and start it by using Virtual Studio. So it's really a compromise here. I'm mainly developing for the Quest 1 and 2 now and I'm currently using the standard UE 4.26 which already allows me to use hand-tracking and most of the recent Oculus features. As for Foveated Rendering I know that you can use it already but I'm not sure if the standard UE version allows you to tweak it as much as the oculus branch. Hope this information helps!

Hello everyone crazy VR Unreal developer here. Has anyone dealt with Ambisonic audio in 360 videos within Unreal? Having trouble working with it and it seems that having to split audio and video just to have true Spatial Audio seems unoptimized. If anyone has had any experience with it please reply

@median idol you ought to ask in #audio. Several ue4 audio devs actively hang out and respond there 🙂

I don't think they've ever had an official C++ version of the VR template though.

#

I ended up gleaning some insight when looking at the config files.. I'm not exactly sure yet but I think I gained some cruft in there from a combination of updating the project repeatedly and maybe editor bugs that aren't reading and writing the config file properly

@serene ridge Is that the exact same template in c++ ?

Has anybody had trouble where a texture looks fine in one eye in VR, but just a "ghost" mesh in the other eye? I have a character created that looks fine on the screen and in the left eye, but the right eye the characters skin (only) is white. All other textures on the character (eyes, clothes and hair) look fine.

Has anyone managed to get an OpenXR enabled project working on an Oculus Quest(2) using 4.26.1? The release notes say that Quest OpenXR support has been added but no matter what I do, I end up with a black screen on the headset. I've made a blank project with a super simple pawn to test this out. The Project was built using Android platform 29, NDK 21.3, Vulkan and armv8-a. Plugins used were the OpenXR, OpenXRHandtracking and OculusOpenXR plugins with the regular OculusVR plugin disabled.

This is driving me nuts, this used to work fine in 4.25, but after the update, the grip state and type seem to reset itself to open/free, and I'm not sure why... Anyone is familiar with what kind of change could have caused that?

I'm trying to debug this but as far as I know there's no way to watch when a value is being changed? If I print type and state right after updating it has been changed successfully, but on eventTick right afterwards it seems to have reverted.

#

Okay I ended up figuring out that I needed to update the BP_MotionController's own "type" and "state" instead of the animBP directly

tired tree
#

@past tiger you can set which mode the motion controllers track to

#

or directly query against it, its one of the "source types"

#

by default everything is in grip (palm) which means that you don't have to re-align hands per controller anymore when using openXR in ue4

past tiger
#

@tired tree Interesting!
I am using the "Right" MotionSource for the right controller, and it is pointing basically up. (Which isn't what I would expect for either Aim or Grip)
R_MotionController->MotionSource = FXRMotionControllerBase::RightHandSourceId;

#

How would I access a different source type?

tired tree
#

with which controller?

#

I believe if I remember correctly that Right/Left default to grip pose

#

and grip is supposed to be your real life palm

#

so depending on what controller you are holding, the pitch would differ

#

however when laying out something like a mesh hand, aligning it to one controller would naturally align it to all then

#

as it is supposed to be the actual location of your physical palm

past tiger
#

I am testing with Oculus Rift

#

I don't see any way to select Grip or Aim poses

tired tree
#

the source is a name

#

those ID ones are just some old hardcoded ones

#

also it would make sense for rift to have a pitch increase on it in palm pose

past tiger
#

Thanks! I was able to get the right aim using FName("RightAim")

#

The aim is pointing forward as expected, but I don't understand why the grip would be pointing up

tired tree
#

is it straight up, or about 60 degrees which is where I would expect it?

#

with how the hand holds those controllers

past tiger
#

It's basically pointing along the axis of the grip, like if you were holding a broomstick

#

Actually, I might understand now. It is pointing along the -Z axis in both cases as defined in the OpenXR specs

#

I finally figured out what the "tube formed by your non-thumb fingers" meant 😄

Well, we submitted to the Oculus App Lab yesterday, but just noticed that it can take 4-5 weeks for approval... Wow. It's very much a curated garden, but not far from a walled garden. SideQuest maybe the best hope for most Oculus VR indie releases as the App Lab is more locked down then they originally explained. Out of curiosity, who else has submitted apps for Quest, how long did you wait, or are you still in a holding pattern?

# delicate isle Has anyone managed to get an OpenXR enabled project working on an Oculus Quest(2...

If anyone runs into this issue, I managed to solve it by calling EnableHMD in my pawn blueprint. It seems as though this function isn't getting called automatically on the Quest in OpenXR - this got me past the black screen . I had another crash afterwards but I think its unrelated since it happens a few seconds after the scene starts. Unfortunately I can't debug it since I can't get the Android Studio debugger working and I think stacktraces have been nerfed on the Quest 2 due to XOM limitations.

Hi.
We have a big issue with Augmented Reality in UE4, 4.25.4. When the state of the AR Session is "Fatal error" I cannot continue handling It, It has no effect if I stop, pause or start the AR Session again, It simply remains in "Fatal error" and the screen goes black. This state appears in the following circumstances, as I have observed:

  • Put the application in the background and return to the application
  • Session is stopped manually and AR session start manually again
  • The mobile goes into sleep mode (either naturally or forced) and exits sleep mode

These tests have been carried out on Android.
Our game is based on Augmented Reality Unreal Template, so I am using ARKit and ARCore.
When I print the string that has additional information it tells me that I should login AR again, it matches what the Unreal documentation says, but it doesn't work.
How can we solve It?

Nothing off-topic about that if you ask me. It depends a bit IMO on where you want to release your game on, if you plan on releasing for Quest then you definitely need a Quest, same concept for PC. Ideally you would have all headsets you want to support, but that usually ends up being a bit expensive 😅
And of course depending on if it’s singleplayer or multiplayer. You can’t properly test a MP game with 1 headset.

Just dipping my toes back in to UE vr dev, considering to finally start porting my Unity project. I noticed that OpenXR is now supported, but disabling SteamVR (and Oculus) and only leaving the OpenXR plugin enabled leaves me with a greyed out VR preview button. What am I missing?

#

So...I'm stuck and I don't know where to go from here. I write apps for the Quest. I develop (mostly) on a Mac. Before you say "Mac's can't do VR!" let me point out again, I'm developing for the QUEST. Up thru 4.25.4, I didn't have any issues I couldn't work around. VSCode worked fine as an editor for C++, and Blueprint VR apps went on to the Quest, no problem. But with the release of 4.26.x, the VR Template is broken because the SteamVR Chaperone is no longer available. (see picture - left is 4.25.4, right is 4.26.1). Also, in 4.26.1, VSCode is once again broken and I can't get it to properly parse headers. Even worse, the code generation for the VSCode templates is calling cl.exe which should be clang on Mac. I don't know where to go from here -- I'm starting to feel like I am going to have to abandon Unreal if they're not going to support Macs anymore. I've submitted a bug related to the Chaperone issue, but it's been more than a week and it hasn't ended up on the list.

I doubt that the SteamVR chaperone is needed for the Quest. You can just delete those functions and remove the references to them from the Event Graph. (Make sure to link the node preceding them to the node following them.)

I see that as just a warning when SteamVR is disabled. That is just to make the controller rumble when touching something. You could remove that, or replace it with OnComponentHit of something else, like the HandMesh?

Oculus is already #ifdeffed out.

#

so even tho I have the plugins enabled, I can't get to the Oculus nodes in 4.25.x. Now I can't get to the SteamVR ones. I don't 'need' them -- I mean, I will later if I want to take advantage of Oculus specific stuff like Avatar or Entitlements. But a BP VR app was working just fine on the Quest. Now I can't work with it in 4.26.

Anyway, so I figured...whatever. I'll just make my own template. And XCode is the worst editor in the world. VSCode worked ok in 4.25, with some fixes. But they broke something new in 4.26.1. 😱

sturdy coral
#

usually things are set up so that even if the platform isn't supported, all the classes are still there for blueprints and stuff, just the implementation isn't defined, based on that STEAMVR_SUPPORTED_PLATFORMS variable, and probably something similar for oculus

serene ridge
#

I believe it has to do with UE not having enough VRAM available and needing to do too much swapping. Something along those lines. Other programs seem to be able to trigger the same issue in demanding games, but RTX voice is especially bad.

serene ridge
#

You can look in to actor clustering / blueprint clustering...

#

Trying to find the specific bad one

#

s.forceGCAfterLevelStreamedOut

#

There it is. Warning: if the level isn't garbage collected and you show it again too soon, it will be like a visibility toggled level (actors will maintain state)

#

The other thing you can do is not ever unload the levels fully, only hide/show them. That is a lot faster to stream.

#

But your blueprint/scripting needs to be set up properly to handle that

sharp thunder
#

memory isnt an issue right now, but even hiding and showing causes the hitch

serene ridge
#

Yep. It's probably the GC. Other than that, if you've got a lot of stuff happening on BeginPlay, (like actors spawning other actors), it can trigger big hitches

sharp thunder
#

will try out that

#

ty @serene ridge

serene ridge
#

Streaming is hard! Good luck.

sharp thunder
#

yeah, i've tried many ways and it keeps happening

serene ridge
#

There were some other console commands similar to that to change behavior while streaming but I can't remember what they were :/

#

When we got close to shipping our game, I did a search through engine source to find every console variable and made a big spreadsheet of them all to audit.

#

UE4.24 had 2910 variables.

#

and in that we found 10-20 hugely important ones that were not set well by default

sharp thunder
#

xD

sharp thunder
serene ridge
#

I recommend setting it to 0, what we found was that you don't want to ever force GC unless absolutely necessary because GC = hitch

#

What seems like a silly question, but I can't seem to find the answer.
I'm using the default VR Template in Unreal 4.25; working in the MotionController Map.
I'm importing some test geometry from Blender.
How to I make the new geometry "walkable" or really "teleportable".
I'll keep googling, but any hints or suggestions would be great.

serene ridge
#

The VR template relies on the nav mesh. You need to make sure that the geo you add is static mobility I think, and you will need to make sure the nav mesh is covering it (might need to rebuild paths)

#

You can press P in the viewport to show the nav mesh I believe

#

Also the collision of the mesh needs to be set up correctly, a lot of the time when you import the auto-generated collision for the mesh is pretty bad

#

@marsh ether ^

#

hope that helps

marsh ether
#

Ah - that does.
I did try to look for NavMesh but I don't know where to look.
It's a good clue, tho.
I'm trying to move over from Unity so there are lots of hangups that I have because I just don't know where things are in the engine.
Thanks!

#

I'll keep playing.

serene ridge
#

Just need to turn off collision on your light blocker

#

There's also a collision view mode which is helpful for diagnosing nav issues

marsh ether
#

It seems that the nav mesh doesn't like interior spaces ... and that was one piece of welded geometry.
I tried separating the "floor" as a separate piece...
And this helped a little...
But recast is doing something far too clever, and there's no actual geometry where it drew the new navmesh...
Humph!

#

I probably need to back off and learn what the heck is going on with the navigation system.

Anyone knows why render texture painting doesn't show up on quest 2?
I have a system to draw on a paper. Works fine in editor, but doesn't show the drawing texture on the quest apk.
Maybe it has to do with the fact I'm creating render target on the bp?
Maybe it had to do with render texture format?
Tried turning on use full precision on material, tried changing formats. Nothing works.

When exiting VR preview, steamVR will "hang", the last image is stuck in the last HMD orientation, only going transparent when looking away. I use desktop+ to keep my headset on, and I've found the only solution is to either kill the game from steamVR overlay (picking controller up to go through this process each time is unrealsonable), or I just turn my head far to the side before hitting escape, but the image still floats around the display. Is there easy way to kill the VR preview from desktop?

Okay this should be a simple problem. On UE 4.25. My game outputs its audio through my PC speakers, not through my Oculus headset. This occurs both in editor as well as a packaged build. Beat Saber, and other Oculus store games, plays in the Oculus headset.

Where do I set the audio to come through the Oculus headset?

Anyone developed a drawing system for oculus quest?
I'm using a system similar to this :
https://youtu.be/DBWzGgJEi1Y

It works great in editor, but the color doesn't show up on my canvas when deployed to the quest (apk, standalone).
It may have to do with creating render target in real time and not setting it to the right format, but I tried changing and still, nothing...
My canvas texture is a png from photoshop. Tried tga as well.
Again, works well in editor /rift mode, not on deployed to quest.
Anyone knows?

Anyone have any experience with this error: "LogHMD: Error: ovrp_BeginFrame4 41597 failed (-1000)" ? It happens about 10-15 seconds into starting a VR preview. On version 4.24.3. Causes a freeze with an hour glass in the bottom right. Picks up after 20-30 seconds and doesn't occur again.

Why does my audio not play when I use spawnsound or attach, but it always plays when I use 2D sound - I've widened the range on attenuation but the sound seems to change whenever I am in VR, so I'm assuming Steam VR is affecting it somehow ?

I'm trying to implement Oculus Achievements.

I've set up the achievements on Oculus' Developer Dashboard and set up the blueprints to Write Achievement Progress (see attached image)

I've also added the following to DefaultEngine.ini

[OnlineSubsystem]
DefaultPlatformService=Oculus

[OnlineSubsystemOculus]
bEnabled=true
OculusAppId=xxxxxxxxx

The entitlement check works but for some reason the achievements don't despite the code executing through the success pin (the play sound executes - see attached image)

I've tried both launching it through the editor and installing it through the Developer Dashboard release channels.

Has anyone experienced a similar issue? Any ideas on how to fix it?

Btw, I'm using version 4.23

Quick question on Forward Shading...
I enabled it, built the new shaders, and everything is pitch black. If I disable my FogAtmosphere, a single frame is rendered. Now all I see is that frame until I re-enable FogAtmosphere and re-disable it... rendering another solitary frame. Anyone experienced something similar?

#

are there any good resources for working with VR in UE4? I've found a handful of not-horrible tutorials but there doesn't seem to be a goldmine of information out there.

sonic lake
#

@bitter temple beside the official documentation and the VR template, which you can study/reverse engineer, there are few videos on YouTube you can watch. A VR introduction from Epic, the channels of DownToCode, CodeLikeMe, Matthew Palaje and your truly if you like (Marco Ghislanzoni). M72TheLaw is Mordentral's channel with updates on the VR Expansion Plugin.

#

There is also the book by Mitch McCaffrey: Unreal Engine VR Cookbook: Developing Virtual Reality with UE4

#

This is another book by I haven't read it: Unreal Engine 4 Virtual Reality Projects: Build immersive, real-world VR applications using UE4, C++, and Unreal Blueprints

bitter temple
#

that second book looks interesting

#

the first one does too but I am just wondering if it's dated already

#

I think I'm going to purchase the second one

#

It seems like it is a good fit for where I'm at

#

I will let you know if I like it

#

Thanks Marco

#

The issue I have with a lot of tutorials is they tell you what to do, but not WHY

#

Give a man a fish, he eats for a day. Teach a man to fish, he eats for a lifetime

sonic lake
#

@bitter temple tutorials are necessarily a trade off between content and duration, otherwise they would be too long for the media. I do my best to explain the why in mine (see for example my tut on room scale snap rotation) but from the statistics I can see that most people tend to skip that part and jump directly to the how. So you are one of a kind.

Hi all,

​​​​​​​I'm beginning work on developing an AR game, but I lack an Android device and while I have an apple device, I lack a developer's license so I can't build to it. How can I build and test my game without these? Can I test in editor on windows? I'm very new to AR dev so I have no clue what I'm doing and the documentation hasn't really been too much help. Any clarity would be much appreciated. Any resources that could point me in the right direction would also be appreciated.

I'm sure there is, just build it for windows and port it to mobile later

Hey does anyone know what I would want to use to create a 2D start menu that the player accesses prior to starting the VR portion of the game? As in are there specific terms I should be searching for?

rustic cargo
#

er yeah, i was saying that in the context of a blueprint only project

#

you can try deleting just intermediate first

solid haven
#

Yeah, I've done that dozens of times, so will try deleting Binares, Build, DerivedDataCache, Saved and Script as well

civic brook
#

I'm not sure if there's a definitive list somewhere, but AFAIK:
Binaries - "built" game (well, the closest that exists before packaging. Runs when you PIE or play standalone)
Config - Project settings
Content - BP Assets & other uassets
Derived Data cache - idk, but it gets regenerated if you delete it
Intermediate - Temporary files used for building the game in the Binaries folder
Plugins - Game-specific plugins not installed to the engine. You'll rarely ever see this folder.
Saved - Saved game data. Stuff like save files, key bindings, graphical settings. Wiping this will clear your save file and stuff
Source - CPP code

#

@brittle crown Add to Player Screen / Add to Viewport might work for you. If you are looking for tips making the 2D screen itself, look up the UMG system

brittle crown
#

Oh I'm good(ish) on making the 2D menu, I'm just hoping to have the player transition between the computer monitor and the VR headset.

civic brook
#

I don't know how to show a separate image in the headset from what's on the screen, but you you add something to viewport then it should be clickable on-screen, even if the VR Headset is still connected. Of course, that will block the VR Headset's entire view once the menu appears, so use carefully.

#

Once you remove the menu from viewport, the headset's view should be back to normal.

#

Unfortunately still the same error even after deleting all the folders above

These two are the errors I find, it seems to be an issue with gradle

thats just input binding, use the same button for walking as teleport

every other movement mode is better with cap rather than holding stick down

@midnight tree It depends on how your teleport is implemented. I implement mine with a custom trace channel that I apply to things that I can teleport on. (In my case, I call it SbGround, which the engine maps to ECC_GameTraceChannel3 in DefaultEngine.ini).

midnight tree

@tough silo thanks bud about 2 seconds after i posted that i came across something that talked about trace channels 😛

i got it sorted

Cool.

i took it one step further and made it a custom object type since the base VR teleport uses object type as its filter

Is this exposed to blueprint? FSteamVRHMD::GetStereoProjectionMatrix creates the projection matrix. Width is by default FPlane((2.0f * InvRL), 0.0f, 0.0f, 0.0f). The 2.0f is the +/-1 of clip space - it is scaling view. Change the 2.0 up or down and you change the fov. (The second line is the vertical one).

#

I'm trying to find it in the docs but I can't seem to find there

Nope, only exposed to native. Originates in the IStereoRendering Interface

@solid thorn Are you trying to load the VREpxansion sample scene or have you integrated it into your own project? I'm using VRExpansion on the Quest 2 just fine, but I'm only using the VRExpansionPlugin part, not any of the OpenVR parts.

solid thorn
#

@delicate isle It's my own project. It worked for Steam VR just fine but launching it on the quest gives me that error. I'm pretty stumped lol. Perhaps it's the engine or VRExpansion version? I think I'm going to try and upgrade and see if that fixes it.

#

It's good to know that it works though so thank you for that.

delicate isle
#

Quest does not support OpenVR/SteamVR

#

Upgrading the engine won't fix it, its just that you're using components of VRExpansionPlugin that aren't whitelisted for the Quest platform.

#

You'll need to find what assets you've included that are referencing SteamVR. My bet is a blueprint node

#

I'm using VRExpansionPlugin on my Quest 2 using OpenXR at the moment, so it can definitely be done

solid thorn
#

hmmm interesting. So what it's affecting is my character blueprint and that one is just the base one from the example project that I just added stuff too. I will have to take a look at it now then.

delicate isle
#

The VRCharacter from VRExpansionPlugin shouldn't have any SteamVR dependencies as far as I know - I'm using that pawn as a base as well.

solid thorn
#

It's just odd how it says it can't find the file for package rather than it is whitelisted or something

delicate isle
#

You could try turning off you SteamVR plugin if you're making content for the Quest, it'll remove any nodes you might include by accident

solid thorn
#

I turned it off already. I can make sure though lol

I spent several hours trying to track down a problem like this before and realised that I had was using a SteamVR enum on the Quest which failed at runtime

@solid thorn that module actually is supposed to be able to be left on for testing on Android, it compile time removes all steamvr code. However during 4.25 I forgot to whitelist android again after some testing so the module wouldn't package out to it

When the engine is openxr entirely anyway it won't matter as the controller detection code in openxr is universal

whats the best way to check that

#

im using an example project for the weapons

sturdy coral
#

you can look on the weapon mesh and see if simulate physics is set

#

but it may be getting toggled off in code when you pick it up and changing into kinematic

midnight tree
#

simulate physics is unchecked for all components in the weaponBP

sturdy coral
#

mordentral's plugin supports physics grips that would probably work better for your situation

midnight tree
#

gotta be a way to dampen the physics on that

sturdy coral
#

kinematic stuff is going to not respond to physics itself and have no leeway

#

and can just cause stuff like that to explode

I've got an issue with my game, has anyone found this or have a solution? If you start up the game without Steam VR, Unreal will start it for you. The problem is, Steam VR is started in such a way that it steals application focus from the main game - cutting the audio as it's out of focus.

#

It doesn't happen with Oculus native.

#

It's probably my number 1 source of support emails / returns for the game.

iron pine
#

@elfin edge You can disable the steam vr plugin

elfin edge
#

Not really an option as it's a VR game. I probably should have mentioned that

sonic lake
#

OpenXR should eventually get rid of this mess about multiples platforms/runtime/plugins

#

If you have both the Oculus Runtime running but also SteamVR installed, launching Unreal with both plugins active results in a conflict between the two. SteamVR is also invoked and tries to take over. If you are using the Quest/Quest 2 over Link the result is that the key inputs are totally gone. The solution may be to stick to the SteamVR plugin if you are distributed through SteamVR and to the Oculus plugin if you are distributing through the Oculus Store (so basically two different versions).

What in the heck is this error? I click on a button to load a pretty light level and it streams in the bigger level with the loading widget i have. It's worked before. But i'm on a different computer. Not sure what causes this. It freezes for like 20-30 seconds, then actually loads the loading screen with the streaming in level.

#

Reading from the above comment, is it possible there is a conflict with SteamVR and OculusVR plugin? I don't remember setting those before, but the oculus plugin has an auto splash screen thing. That's what the error looks like almost. I don't think there's any splash screen. Unless the transition screen shouldn't be set in the maps and modes section.

sturdy coral
#

@elfin edge there is an option somewhere to not change out of focus audio

# 
[Audio]
UnfocusedVolumeMultiplier=1.0
#

it can still be a good idea to detect if focus is taken from the game and prompt the user about it, because windows will priority boost the focused application

#

(don't make prompt impossible to dismiss without focusing though, because streamers and stuff don't necessarily want it focused)

#

You can have Oculus and SteamVR plugins enabled - it's only if you're pushing to the Oculus store that you need to disable SteamVR and remove any Steam relevant logic from your BPs

#

Like Mordentral mentioned above, OpenXR will fix a lot of these problems 🙂

Hi, in AR when tracking images, is it possible to check if ARTrackedImaged is still in view of the camera? I need a solution for both ARCore (Android) and ARKit (iOS).
I tried using GetTrackingState() of the ARTrackedGeometry, but it is always set to "Tracking" (even when the image is covered or not in view), for both iOS and Android.
Please, is this supported by the plugins?

# torpid sandal Hi, in AR when tracking images, is it possible to check if ARTrackedImaged is st...

I found this in GoogleARCoreResources.cpp

ArAugmentedImage_getTrackingMethod(SessionHandle, ImageHandle, &TrackingMethod);
switch (TrackingMethod)
{
  case AR_AUGMENTED_IMAGE_TRACKING_METHOD_FULL_TRACKING:
    // The Augmented Image is currently being tracked using the camera image.
    TrackedGeometry->UpdateTrackingState(EARTrackingState::Tracking);
    break;
  case AR_AUGMENTED_IMAGE_TRACKING_METHOD_LAST_KNOWN_POSE:
    // The Augmented Image is currently being tracked based on its last known pose,
    // because it can no longer be tracked using the camera image.
    TrackedGeometry->UpdateTrackingState(EARTrackingState::NotTracking);
    break;
  case AR_AUGMENTED_IMAGE_TRACKING_METHOD_NOT_TRACKING:
    // The Augmented Image is not currently being tracked.
    TrackedGeometry->UpdateTrackingState(EARTrackingState::StoppedTracking);
    break;
}

I guess someone had a right idea of setting the tracking state when the image is occluded. However UpdateTrackingState() is being called all over the place and probably setting it back to "Tracking". Unfortunate.
But I managed to get it to work by just calling ArAugmentedImage_getTrackingMethod() myself and not relying on the TrackingState. So this solves it for ARCore at least.

torpid sandal
# torpid sandal I found this in GoogleARCoreResources.cpp ``` ArAugmentedImage_getTrackingMethod...

ARKit seems to be a different problem. There is also an idea of setting the TrackingState in AppleARKitSystem.cpp.

FoundGeometry->SetTrackingState(AnchorData->bIsTracked ? EARTrackingState::Tracking : EARTrackingState::NotTracking);

No idea if something is overriding the tracking state, or the ARKit by iOS is just not updating it. But it is difficult to check, cannot get a reference to "ARAnchor". "AllAnchors" is private in the AppleARKitSystem and NativeResource is not set for the UARTrackedGeomerty in ARKit plugin. Unfortunate again.

hi what is the easiest way to get smooth locomotion and gravity in vr? the default vr template has only teleport.

Easiest way would be to add world offset till your player hits the ground

And add world offset until player hits obstacle to have a smooth walk

Hi, does scene reconstruction work in UE4.26.1 using ARKit? I tried to use:

IsARSceneReconstructionSupported(EARSessionType::World, EARSceneReconstruction::MeshOnly)

It returns false for each combination of the input parameters. When I try to copy-paste the content of the function to my custom function, it returns true.
Does someone encountered this problem, please? Am I missing something? Do I have to enable something in the Engine?
I am using iPad Pro (12.9-inch) (4th generation), it should be supported, LiDAR works using other apps from AppStore.

I've come across something weird. I've set up input axis mapping for Oculus touch controller Trigger and the axis seams to interpolate over time rather than give a 1to1 axis. anyone know how to turn this smoothing off?

latent ferry
#

https://imgur.com/a/YW9phtt

in that video I'm scaling the mesh directly off of the axis value coming from the trigger input and you can clearly see the value interpolates rather than snaps, its particularly clear when releasing the trigger and seeing the mesh scale shrink over a few frames rather than snap to 0

#

I believe Oculus Touch also has an action mapping input that would appear more like a button press.

latent ferry
#

@past tiger Yup, understood, I just feel some kind of interpolation on that axis

I think I see what you mean. Like the values are being interpolated after you've released the trigger.

Hey you beautiful people. I've created a part 2 to the VR fuse box puzzle tutorial I released last week. I was asked how we could upgrade the fuse box by adding static meshes to the current blueprints and how we can set it up so the player can place objects in any location but only have the win state fire if it's in the correct position.

There's a lot of possibilities for this set up and i'd love to see how you guys implement it into your projects. Remember It doesn't have to be for an escape room, maybe it could be used for:

  • Weapon Rack
  • Using a Key to unlock a door (might be a video soon)
  • Attaching items to the player (Hint, Update the fuse actor location on tick)
  • Create a VR tablet which can attach to locations to read data.

Just to think of a few, There's so many possibilities. Let me know what you all think.

Do you have your oculus app open? Open oculus app 1st then unreal and see if it works

@past fulcrum that one above was 4 you

I am pretty blocked. Stereo layer depth question. On VR preview my stereo layers respect depth but when I cook they render on top of everything.
Documents suggest that oculus would “always” respect depth regardless of checking the checkbox on the stereo layer. And all the topics I can find fight with the opposite problem 🤦‍♂️

Any and all clues would be appreciated.

Hey. Technically, this is a "non-vr" question, literally taken. Our app can be used in VR and non-VR, which is determined based on whether a HMD is connected - However, Oculus and Mixed Reality Portal still open up on launch when using non-VR. Do any of you know where that is initiated, so that I can prevent it? We use engine source, so I can fiddle around in there, but I can't seem to find where thats done

Did you do anything to the template, or is it literally a fresh template project that crashes?

serene ridge
#

Does anyone know of a VR foundation project? I saw someone post something a few weeks back. It came with typical movement and multiplayer already built up

tired tree
#

@serene ridge what about it? And VR Foundation Project is actually a good name

serene ridge
#

I was trying to find it (but then managed to find it in my browser history). Wanted to check out if it would work for me. I don't think it will work just stock, but it may have some stuff I can use still

#

After checking out the demo project, I'm quite sure I've played some released games based on this though.

#

@tired tree Ah, you're actually the author of that project aren't you! 🙂

#

I suppose I have a question for you in that case.

So the default behavior in the demo for this project is that when you try to put your head through a wall, it pushes you back. In my last game what we did was let the player put their head through, but then we would prevent them from sliding further in that direction if doing so would put them even further through a wall...

So you could stick your head through walls and you could slide back into the "allowed" space, but it would prevent you from sliding further out. Is there something like this available in your plugin?

#

It's hard to explain this very well, but we basically had a collision proxy for the player which what the player input really moved, and then that movement would get mirrored onto the HMD offset (and in between player input, the proxy would keep trying to reach the HMD so if you weren't in a wall it should be equivalent to moving normally)

@past fulcrum has your quest worked on any games on PC? I think you need the oculus software to begin with

#

@serene ridge I have a seperated walking and locomotion collision setup that is available where you can walk IRL into a wall but cannot locomote into it (sounds like what you were doing mostly?). I do not have seperated collision no as I try to maintain as much of the default engine character intact as possible.

#

that being said, the character is just one part, and the other parts of the plugin don't require it.

serene ridge
#

Cool. I'll have to check out your approach then. Locomotion in vr is hard! 😂

tired tree
#

@serene ridge the way mine works is two seperate collision channels, if only walking roomscale it uses one, however if locomotion is active it uses the normal character collision setup

#

if you want a wall roomscale walkable you would ignore the roomscale channel

#

but if locomotion is active it would still block, even if walking in roomscale

serene ridge
#

Would you be able to physically walk through the wall, and then keep locomoting after that? Effectively phasing through the wall?

tired tree
#

yes unless you ran some logic to lock locomotion

#

its mostly for tables the like

#

as most users want the push back

serene ridge
#

Right that makes sense

considering its becoming fairly standard

Makes me sick when it happens but yeah I've been seeing it in more games

push back does throw an event btw

though its a bit complicated to setup from what I understand

#

I wrote this in the unreal engine channel, but surely this is a better place to put it (I didn't find this before as there are so many channels), I won't repeat the whole thing BUT, in short.

Do you guys know any good tutorial in how to make vr multiplayer games in blueprints ?

#

I have foudn either multiplayer (networking) or VR but not both

serene ridge
fading jay
#

I'll check it out

tired tree
#

@fading jay VRE aside, vr networking is no different, you just need to handle some extra client side controlled objects. So learning engine networking at the base level is going to be important

fading jay
#

I was checking videos in youtube about how the whole networking thing works, my main issue with this, that got me to come and ask for help, is that usually the engine / game just crashes, there is no helpful error or anything to maybe point into what's going wrong

#

and given that I didn't really find a vr video that explains the logic behind initializing vr on the engine / pawn etc

#

I am a bit lost 😄

tired tree
#

there are quite a few vr tutorials out there, including the official documentation

#

as for a crash, the engine writes out logs, its actually fairly hard to force a crash from blueprints rather than a infinite logic loop or something

fading jay
#

well, it turned to be quite easy for me :D, to be fair in the last 3 days of development the crash screen has been a big part of it, and yes, there are logs, and I have found them, but they don't really say useful things, nothing seems so terribly wrong as to crash the game or the editor.

serene ridge
#

If you can't figure out why its crashing sometimes attaching the debugger can help to catch it before you get to the crash report screen and get you some more info.

#

But that does get into looking at engine source and deep engine debugging real quick. 🙂

fading jay
#

I will keep that in mind, but I am looking at the videos from VRE and this looks like it is 100% what I am looking for

#

I am new to unreal, I used unity a lot, but I can't just deal anymore with the networking changes, I just can't

#

so I want to learn more UE, beyond the tutorials, I actually want to do something

#

we'll see

#

I'll stick around in this discord tho, it was very welcoming

tired tree
#

@fading jay VRE is my plugin actually, I just don't recommend it to newcomers to the engine usually. It has a dedicated discord for direct support for it as well

fading jay
#

I saw that

#

not that it is yours

#

but that there is another discord, I will watch the videos, and see what that gives me.
I have a couple of hundreds of hours of tutorial and course videos on unreal

#

I just never managed to do anything with it

#

then again, I am at the stage that I will continue learning only if I run into problems

#

(I was kind of expecting something that wasn't a crash window tho 😄 ahjhah )

#

In terms of damaging the headsets, no I haven't had any issues with it... Sometimes the drivers/software I think gets confused though and it does require a reset occasionally. Ideally you want to set your work up so that you're not needing to go back and forth very much.

#

Some of the others I've worked with just used multiple machines if they needed to be switching more frequently

#

But that comes with its own set of challenges

short laurel
#

Yeah - havent decided if I wanna target quest native or pc vr... once I do I guess it will make sense to just leave one connected for the majority of time

multiple machines is good idea - have a laptop on desk too

and the laptop gpu is pretty iffy

sage gulch

you can use other pawns fine afaik but they may or may not have support for HMD or Motion Controller built in, etc, then you may face integrating that functionality somehow if desired

So VR pawns need to be set up in much weirder ways to deal with the physical hmd offset from their room centers

sage gulch

is there a trick to setting the Oculus audio buffer or something? It stutters so bad the game crashes but if I build it to start without VR then it's fine

sage gulch

if I build with the OculusXR plugin, the audio playback correctly but it's coming out of the desktop speakers...

sage gulch
#

on a whim I've got OculusVR plugin, Oculus Audio plugin, Oculus XR plugin, Steam VR, Open XR.... all enabled and it still plays OK but from the desktop speakers. If I whittle back plugins until the audio is sent to the HMD then it's stuttering like mad

@icy laurel That D3D-crash has been the plague for a long time. It's specific to hardware/driver combinations. Make sure Windows and your GPU drivers are up to date, and appreciate it if you hit "send" on the crash reporter every time (it's important even though it might seem redundant).

sturdy coral
#

@hallow knoll fwiw the most recent drivers (at least as of a couple days ago) have a window blanking issue and were blacklisted

#

I was having it and had to roll back to something earlier

#

ah the title of that commit is a typo I think, it says 462.40 but the commit blacklists 461.40; a new driver is out today so maybe that addresses the issue

#

I had rolled back to 460.89 based on an answerhub answer someone found but I'll try with t he latest.. totally separate from that d3d crash but looking at the stack trace in his screenshot I think did a work around to fix that issue too

#

if you turn off depth submission, that will see that it is off and prevent some part of the depth texture swap chain that was causing a crash

Is there a way to set an input ReleasedKey event, so that it is still listening for that ReleaseKey event, even after the input is lost?

I have an application where I am using a 2nd screen (Spectator screen) to score the VR Player. It is setup to immediately return input back to the VR player, but when it takes it, any logic tied to the Press/hold & Release, is interrupted -

I tried setting up some logic to prevent the event tied to the ReleaseKey button (when it gets unintentionally triggered when the BP loses input for a split second) but the problem is, when input is restored back to that same BP, the ReleaseKey will never fire, because the system has recorded that it already has, even if it really hasn't.

If I could initiate an event from that spectator screen TO that blueprint that basically said, "Okay, flag this button as pressed now" so the system would start listening again for that OnRelease, then I think I could make this work.

#

I just need to be able to say, hey, this "Button1" set it to "Pressed" now, that way the system will be listening for the "Button1 Released"

serene ridge
#

Ok... so my crazy plan for handling vr locomotion and collision detection is either...

  1. Make the player collision proxy a separate actor from the player pawn / vr camera, and let the player pawn drive it and mirror movement from it
  2. Keep the collision proxy and camera in the same actor, but make them share a common scene root that will always be at 0,0,0... and then I would move the vr origin and the collision proxy components independently inside the actor...
#

I can't decide which of these is more sensible. I like option 2 because it keeps it all in one actor, but there's still some weirdness to it. I'm not sure if there's some other advantage to having the collision proxy be it be a literal actor rather than just a component.

tired tree
#

singleplayer?

serene ridge
#

Ah. Multiplayer, but it's co-op so player positions won't be critical. I plan to force the co-op player's avatar to show at the collision proxy, not the literal location of their head, so the avatars never go through walls

tired tree
#

then all in one will be easier

#

if it was single player the other way around

#

going to be some huge syncing issues decoupling local perspective and remote though like that

#

unless its literally puzzle solving

#

and no real interactions

serene ridge
#

The desync should only happen if people stick their head through walls, otherwise the two positions should be identical.

#

That's my theory at least

tired tree
#

say they walk into a wall, travel a bit at the right angle

#

and walk back out

serene ridge

#

are you having the remote perspective follow at the wall, or snap to the new position

serene ridge
#

the collision proxy will keep trying to reach the player while they are out in the void, so it should slide across the wall

tired tree
#

and if they walk through a gate or something like that?

#

in the wall next to it

#

guess you'll have to keep the local player blinded until the collision body can re-sync

#

within some threshold

#

i know that MuchCharles is / was using a setup like that

#

for his multiplayer setup

serene ridge
#

Cool, I'll send him a message too. I did something similar to this in Gnomes & Goblins, but that was a singleplayer game. It wasn't done as well in terms of the hierarchy though as I'm thinking of doing now, so there was a lot of special case rewinding positions during movement to ensure the components would move independently (which then caused issues with overlap triggers).

tired tree
#

there will always be a ton of special cases with a setup like that

#

but is doable

serene ridge
#

Yeah. I'm not sure yet how I will handle moving platforms

tired tree
#

in non action games no real reason not to handle it like that

#

same way as the std character

#

find the floor object and track it

#

if its something you can stand on

#

it just injects in your offset calculations

serene ridge
#

I imagine you need to make sure the floor movement is happening before the player's tick?

tired tree
#

all of your hmd to collision offsets should be done in relative space anyway and converted to global

serene ridge
#

floor object*

#

otherwise you'd sink into it a little

tired tree
#

you are free to run your player tick during update or something, doesn't sound like you need much physics interaction

#

but yeah you could also manage ticking when it detects a new movable floor

How the heck does the game thread work on different windows? Can't I make a bind event to losing/gaining input? if I did, I could find a workaround with this

unknown.png
#

sorry, that's a bit confusing - but the moment I click that second screen (the orange box) it fires the event on Released, even when they are still holding down the player

#

I understand that losing input does this, I just can't figure out how to reset that key, so the split second loss of input, when it regains input (that control window has a function that immediately returns input back to the VR player) and then I can set that key to a PRESSED state, so the input manager will keep listening for the moment the player actually does release the key

same controller inputs and bindings and everything

#

(and the audio plays ok on XR, but out the desktop speakers, but building for Oculus native it's sent to the HMD headphones properly but dropping audio even when at good fps)

any way to manually adjust the buffer or latency on Oculus audio?

#

@serene ridge I have the character just walk towards the head when not using the joystick on the controller, and follow input when using the joystick

#

only main issue was with turning due to how that is done at an early stage of pre-ticking input or something, originally intended for mouse responsiveness or something I think

#

I also do a bunch of heuristics on reaching the head to let you lean around and stuff without walking the character, for full body ik stuff

#

basically just the taller you stand the more tightly I try to match the head (because you can't be leaning when standing tall), and I give more slack for leaning forward than side to side and expand the threshold the lower you go

Hey guys, don't know if anyone ran into this issue, but our game runs perfectly in the editor, but when we try packaging it - the input system just doesn't work, no matter which headset we try. Did anyone run into this? or have an idea how to solve this?

serene ridge
#

I like that idea though. I think it would be pretty easy to add to what I already have... move collision proxy towards the head like I'm already doing, and then as long as the proxy is close enough to the head apply the Z offset to the player camera as well...

#

But your video does identify another piece that I am working on, which is that I want to smooth out any fast vertical motion so the player doesn't get sick.

#

I think that is important, although it may be better handled by just hand crafting the player collision rather than trying to do something fancy in the code. Otherwise I would be trading off responsive movement (going up ramps) to smooth out the jitter (up/down movement would get delayed slightly on ramps)

serene ridge
#

@sturdy coral That really is a very cool idea. It was really easy to add to what I've already got too. Great stuff. 🙂

From a developer point of view what do you think is likely the best VR headset for being able to fully utilise the hardware in Unreal or just in general? HTC Vive or Valve Index? Do they both allow you to add on trackers for your own custom motion tracking solution for example ... I am not buying occulous as it demands facebook use and because they cancelled their go api support after 2 years which seems ludicrous to me. Not a fan of their business choices right now. I heard that you can use add on controllers interchangeably between HTC and Valve which sounds good. If anyone has a good link to a more developer oriented article that weighs the pros and cons of the two I would appreciate it.

@vivid summit @short laurel

My experience on the Oculus quest and quest 2 with link cable was horrible. I tried two different cables and it just kept crashing. The only reliable way to test my games were to load them to the quest and launch them from there. The crash wasn't about the device going to sleep mode or anything either.

I got a chance to try the rift s. This headset was literally plug and play. It did not lag/stutter like the quest+link and it didn't crash once. For a different project using Unity* I tried the rift s but the controllers were constantly vibrating for some reason I couldn't yet solve.

I also temporarily had access to a vive pro which was even better than the rift s. But I had to deal with base stations.

Now I ordered an Index for myself and I think either an Index or Vive will do great for development. In my experience, if you want solid development, stay away from the quest.

#

@short laurel
I wanted to get a Vive pro first but I thought getting an Index with warranty would definitely be the better choice.

Getting the Vive Pro second hand is also really hard. Chances are you will find the headset alone (without controllers, basestations etc) for an absurd price. And if you find a full kit, it's going to be priced high without warranty.

fathom temple
#

I use a Rift and the Quest. If I am working on a Quest project, I test on the Quest without Link as often as possible. I would like to get a Vive or Index to use for testing, but can't justify it yet.

tribal lintel
#

I would say valve index checks the most boxes, with one more box checked over HTC, finger tracking. there is a repo out there on github that allows you to access the 3d passthrough of the index, enabling it to develop AR applications, the only thing you might be missing is eye tracking from the hololens. Index you can add base stations, other trackers for full body. HTC Vive or index, most headsets are pretty interchangeable with parts, but if you wanted to use HTC controllers with a index, or vise versa, you will need to track down some good dongles with a specific chipset. The index has 2 dongles in the headset, 1 per controller, this is standard, but it would allow you to buy an index, buy HTC controllers, emulate the HTC vive on the index

Hi guys, I'm trying to think of the way to implement 3d widgets (especially curved screens like one in Oculus Home, or floating text). My config: Oculus Quest 2 with 4.26, Vulkan supported toggled
My main problem is for the widgets the default anti aliasing for the platform isn't enough ( I have "jittery" lines and such). What I've tried already :

  1. Stereo Layers with depth support - text is very crisp, but everything else is black and isn't rendering, I'm guessing this is because it isn't supported on this platform yet officially. Without depth support it just renders above everything else
  2. Since it is not advisable to turn up the AA more then MSAA 4x (and it is already hardcoded into the settings) and everything else looks fine I can't solve it that way
    Maybe anyone had this problem before?

Hey, has anyone worked with WorldToMeters and had problems with the controllers taking time to return to their original position?

@hushed nova controllers only update their positions on their tick, you would either want to set worldtometers directy before their tick, or manually in c++ call thier PollTracking function after changing it.

Hey does anyone know how the big vr games have those hand poses for each object? Do they adjust the fingers manually for each object or what?

@tired tree so I should use AddTickPrerequisiteActor in the motion controller actor, and the prerequisite should be the actor/component that is setting the world to meters right?

@hushed nova yes

when it polls current relative transform it uses world to meters to calculate it

you could also manually set the controllers relative transform based on the difference, but this would likely be easier

this is a few frames, controller location and worltometers keep changing

back and forth

because I'm setting worldtometer based on the controller location

tired tree
#

oh

#

well thats going to be a bit different

hushed nova
#

I'm trying to do something like the VR creativity apps where you grab the world and resize it

tired tree
#

you need to alter your offsets as well when you change world to meters, or base it off of a percentage of difference biased around the HMD

#

you don't want to base it off of the controllers last and current position without accounting for the new scale

hushed nova
#

so I should offset the controller location based on the previous world to meters and the new one right?

tired tree
#

this is also unaltered position I beleive

#

ah, no that also uses world to meters, never mind on that

#

and yes you would have to either account for the changes, or base everything off of the hands relative to each other

#

or relative to the camera in percentages

#

@hushed nova you could also get the current world to meters and divide the position by it to get everything to base line and work off of that

hushed nova
tired tree
#

@hushed nova you shouldn't be working off of actor location, roomscale is in relative space, you are adding in the actors base location to that

#

you want to work with the controllers relative position and then convert to world if you need it in world

#

also I think that dividing by world to meters and working with baselines is going to be easier for you

hushed nova
#

@tired tree I should get the controller relative to the pawn or the HMD? and also divide what by world to meters? If it's the controller location then I'm essentially already doing that in the code above and multiplying the location by the new world to meter

hushed nova
#

I'm trying to change the controller location based on the position of it in the last frame and on the world to meters but it's also not working that well

tired tree
#

@hushed nova you don't need to multiply, when tracking positional change just divide down to get the base and work off of that from frame to frame

# nimble raven im developing in Unreal 4.26.1 and I am attempting to launch to the Oculus

I've got bad news for you. Ever since 4.26 came out, I've been unable to deploy a Quest app from my Mac. The basic VR blueprint doesn't compile due to the Steam Chaperone being removed (mac only). Creating a C++ app from scratch also doesn't work. All I ever see are 3 dots. I did some looking, and buried way, way down in the Unreal 4.26 release notes, I found: New: Removed VR support for Mac. No longer supported and not compatible with current/future Mac updates. They're at https://docs.unrealengine.com/en-US/WhatsNew/Builds/ReleaseNotes/4_26/index.html

The Oculus libs aren't compatible with Mac -- even tho we're building to the Quest. You can't access them and they won't build from source. You can see for yourself in this image. There's no "Oculus Library" section.

@worthy cave the only real way I know of is check out your old 4.25 revision from source control, upgrade it to 4.26, then use the blueprint diff tool against your real 4.26 version. Looking at the diffs, manually backport the changes by hand to a second checkout of the 4.25 version

#

probably much easier to just stick with 4.26 and wait on a stereo layers fix, or comment out the stereo layers stuff and use the generic base class implementation (which is only rendered in game and not through the compositor, so won't work for loading screens)

# idle osprey I've got bad news for you. Ever since 4.26 came out, I've been unable to deploy...

The VR template wouldn't work on the Quest anyway due to SteamVR dependencies. I managed to push Quest apps from a Mac last year by #ifdefing the Oculus blueprint function bodies out and whitelisting the plugin/modules I needed. This let me place Oculus specific blueprint nodes that would then start working when I pushed to the headset. I haven't dug into the 4.26 Oculus plugin changes yet since I'm trying to shift to OpenXR but I will attempt the same trick when trying to push OpenXR content from a Mac to a Quest.

dreamy ivy
#

the vr template works fine on the quest.

delicate isle
#

Oh does it? That's good to hear

#

I've been rolling my own using VRExpansion plugin

dreamy ivy
#

yeah, it works fine. in some cases though you need to disable to steam VR plugin and disconnect the room scale function but other than that it works great. Also you mention MAC im pretty sure vr development on mac has been stopped on 4.26

delicate isle
#

I mainly stuck to the OculusInput module when exposing the nodes to mac since I wanted my students to play around with hand tracking

#

Again, I'm not targeting a Mac, I'm targeting a quest

#

The cross compiler handles all the VR stuff

dreamy ivy
#

yeah, but building your game on a mac for quest is not possible anymore. I could be wrong though.

delicate isle
#

The thing is you're just building for Android, any Quest specific stuff just gets packaged along the way

#

I can't render VR on a Mac but that's not the problem

dreamy ivy
#

but your unable to access the Oculus plugin settings within unreal since the oculus desktop isnt supported.

#

unless you know of a way to show the oculus plugin without having the desktop application installed

delicate isle
#

Open the project on Windows, change every Oculus plugin setting at least once to store them in DefaultEngine.ini then use that config on Mac when pushing to the Quest

#

Just because the plugin doesnt load doesn't mean it won't respect the settings during packaging

dreamy ivy
delicate isle
#

That's how I got the hand tracking working from the Mac

#

Yeah, I get it but we're not talking about running VR in a Mac, just packaging on a Mac for a Quest...

#

If that means that they no longer whitelist the HeadMountedDisplay engine module for mac that might be a larger issue

#

Sorry, I'm on my phone right now so I can't delve into the source

dreamy ivy
#

no worries, I took the screen shot from the 4.26 release notes. but surely if they are discontinuing VR support on mac then you can assume they will eventually get rid of the HeadMountedDisplay content or it will become obsolete.

@idle osprey Are you packaging the Oculus plugin to the quest using "Additional asset directories to package"?

I mean, I'm not trying to do anything oculus specific.

#

@idle osprey I'm working on it since I have to upgrade our class lab to 4.26 with Quest support otherwise I'm in trouble :/

#

Hence why I'm putting all of my eggs in the OpenXR basket

idle osprey
#

Also, Mojave is the lowest OS they'll now support, so that target's moving, too

delicate isle
#

We're on Catalina atm

idle osprey
#

I'm on Mojave. I'll upgrade when I need to.

#

But please, keep me informed on your progress? Take notes! 🙂

#

I really don't want to be banished to ||Unity||.

#

I actually know it better than Unreal, but I just spent the last year learning 4.25 in my spare time.

@idle osprey Give the plugin packaging thing a go. I found that I couldn't push a vanilla project to the Quest from a Mac around June 2020 without adding /OculusVR to the Additional asset directories to package option. It was because the plugin at runtime was attempting to load a pokeahole material which was never cooked and copied. I don't know how you managed to get it working without that option, but its worth a try. I only found out about it by perusing the verbose adb logcat output in depth until I found errors about missing materials

idle osprey
#

No, never had that problem at all. Neither in a Blueprint nor C++ project.

#

I've done the GameDev.tv's C++ VR course on a Mac. I had far more trouble with VSCode than the Quest.

#

sure, the postprocessing didn't work...but that was all.

#

This is where you go if you have issues with vr stuff right?

idle osprey
#

One place, yeah.

hasty wing
#

Ok cool. I'm having trouble with getting the pawn to rotate with the headset

idle osprey
#

C++ or BP?

hasty wing
#

BP

idle osprey
#

And you didn't start off with the template?

hasty wing
#

i did?

idle osprey
#

That should work right out of the box. Quest or Rift or ?

hasty wing
#

quest. ill look into the bp's real quick

#

yeah there isnt anything with rotation

idle osprey
#

k, it should just work.

hasty wing
#

just teleportation. I can look around just fine but im trying to get the pawn to face where the player is looking

idle osprey
#

ok...let's clarify a few things

#

when you say turn...do you mean if you turn your head?

hasty wing
#

yeah

idle osprey
#

or do you mean snap turning and smooth turning?

hasty wing
#

turning my head

idle osprey
#

because you have to add those yourself. But you should be able to look around all you want.

hasty wing
#

Yeah I can look around fine but the player pawn isnt turning with my head

idle osprey
#

ah, yeah. ok, no it won't.

hasty wing
#

why not?

idle osprey
#

You have to add a lot of code.

#

Well, because the VR template sucks, actually.

#

it's very bare bones.

hasty wing
#

yeah lol

idle osprey
#

How's your C++?

hasty wing
#

I haven't done much with it

idle osprey
#

k, there's some "free" courses you can take. both a C++ class and a VR C++ class.

#

After taking that class, I started to work on a new VR template that handled room scale properly, smooth movement, smooth and snap turning, etc.

#

But then this mess you'll read above happened, and I stopped working on it.

hasty wing
#

oh

idle osprey
hasty wing
#

ok cool. One more thing, is there a quick and/or easy way to get the players height?

idle osprey
#

you can get either the camera or the hmd

hasty wing
#

ok cool. Thanks!

#

@hasty wing if you turn your body in the real world then the player will turn and when you move your head to look around you also turn. I'm a bit stumped on what your trying to do.

Is it possible to increase the size of "Print String" text in VR without straight-up creating a new widget? I literally can't read it when it's all the way in the top left.

idle osprey
#

not with that debug node, no

Your own strings that i know of

delicate isle
#

I like that idea, I'd love to place the log in world space

real swallow
#

Hi I want to spawn Normal pawn in PIE and VR pawn in VR mode?
If there any way to check whether player is in playing in VR?

agile grotto
#

What component is getting translated when you look around in VR? Like where can I find the rotation, is it just the characters camera component?

tired tree
#

@delicate isle there is an engine plugin that renders the output log and I seperately also have an opensource file that renders the output log to texture (console too)

#

then you can just display in world as you wish

#

@agile grotto yes its just the camera component, the camera component acts as your hmd proxy in game, with its "root" components position being the center of your tracked playspace.

agile grotto
#

@tired tree If i wanted to reset the rotation, I thought I would just use SetRelativeRotation to zero - but this doesn't appear to actually be doing anything?

tired tree
#

@agile grotto the camera will always track the hmd by default unless you turn bLockToHMD to false

#

so it would just reset itself again

#

or applying a manual offset to the cameras root

agile grotto
#

I'm trying to include an option that switches from VR to regular view on a monitor, so I set EnableHMD(False) and then subsequently try to reset the orientation to ensure that there is no unwanted roll or other rotations

#

Any ideas if I have to set bLockToHMD false if I were trying something like this? @tired tree

#

thanks for the tips so far

tired tree
#

if vr mode is off it should no longer track yes

#

shouldn't have an issue at that point

agile grotto
#

hmm, yeah I'm still having issues and can't work out why

I'm having issues where my user is accidentally activating his binoculars - the normal use is to bring them both motion controllers to the head collision - each one increments a variable and every time a collision event is checked, it checks if that increment is 2, if it is, then it activates them -

**Am I wrong in assuming that the issue is probably tracking related? **These are on a custom collision channel, so nothing else can be triggering them. But i was thinking about it and if the tracking isn't perfect, the intertia of the collisions might keep the mesh moving even when they don't, and cause it to collide falsely. (but in terms of the game engine, it IS colliding)

tired tree
#

@trail shale would be better off manually checking bounds between the bino's and a head collision zone than relying on hit/overlap events generally when you are handling things with controllers

#

its a fairly cheap calculation and one you would only have to do when the binoculars are held anyway

#

if there isn't an actual binocular model than that is a bit different of course

#

but yes there will be some jitter in and out

trail shale
#

And also I toggle the binoculars viewpoint that just sets the a plane to spawn right in front of their eyes, and the plane is set to a texture of a scenecapture that is projected ahead of the player (all control meshes are hidden when this occurs)

@idle osprey The patched Oculus plugin? I have one for 4.25 but haven't had a look at 4.26 yet

idle osprey
delicate isle
#

@idle osprey From a quick cursory overview, I can see that Oculus have actually implemented exactly what I did to get the plugin compiling on the Mac originally, which is to wrap all Oculus specific code in #ifdef OCULUS_[MODULE]_SUPPORTED_PLATFORMS conditionals. The #platform define is set in the module interface header.
What I did to get the modules loading was just to add Mac to the list of whitelisted platforms for the modules that I wanted to expose functions for - in this case I focused just on the Oculus Input module since I wanted hand tracking nodes. Here's my 4.25 branch with my tweaks if you want to take a look. https://github.com/Mystfit/UnrealEngine/tree/mac_oculusinput/Engine/Plugins/Runtime/Oculus/OculusVR

#

Just to reiterate, this was just to expose Oculus blueprint nodes so that I could get the project packaged on a Mac for a Quest android platform, not to run on the Mac iteself.

Haha, it's absolutely fine, I'm just writing that for anybody who searches for this conversation later on
