running the double eye mirror or the direct compositor output between two projections should be "ok", little curious why you are trying to project eyes like that though
without the distortion and things and the ipd settings its not going to be perfect
the nvidia display thing would be a far better option if you are trying for a CAVE like setup
brisk spade
ok then i will invest some research into how nDisplay works
yeah its more like a cave
but without any interaction at all, only viewing people who wanna see it in stereo 3d
but it needs more pc, thats a problem
void raptor
does anyone here have any issue with "visibilitycommands" in stat gpu, its really high for me (3ms) and kills my performance, but only on oculus, my team with index and vive has no issue with it (they have 0.02)
however if we play in nonvr its at like 2ms for all of us
sturdy coral
@void raptor that is likely this issue: https://answers.unrealengine.com/questions/431377/gpu-performance-tuning-of-hzb-setupmips-as-seen-in.html
if you tweak things enough to get it to stop showing on visibility, it will likely just bubble over to something else

Hey guys, apologies is this is asked a thousand times a day. I'm relatively new to developing in general so I'm noticing a lot of core game dev concepts are wholly skipped over in VR tutorials on the assumption that this is an addition to a previously built aspect of a game.
I have no problem understanding and utilizing these tutorials, and I'm pretty happy with some of the neat stuff I've built for my game following tutorials that taught me stuff outside of the core mechanics, but I am fundamentally failing at core aspects, like getting a gun to shoot after picking it up, or how to make it so I don't constantly move in a single direction with smooth locomotion active.
That being said, is there a tutorial out there on how to make a basic VR shooter kinda deal?
I've found a couple that use guns that are in place of the motion controller, but implementing their code and adapting it to an external gun never seems to work and I feel very dumb and bad at this.
Any help would be awesome
void raptor
@sturdy coral ty for the response, maybe it is yeah, will look into it thanks 😄

I've been working on a VR project in 4.23 and have some wierd behaviour with the default spectator view in both build and in editor play. main issue is that the windowed view seems to magically decide it's own res and the top coordinate is off screen AND when I start the packaged game the game window doesnt automatically take focus so no audio can be heard until/unless I click on the window. You can put on the HMD and intereact with the whole build without having the window focussed and therfore no sound. Any ideas how to fix either of these problems?
rose totem
@tired tree cheers, though for clarrification the window bit, or the audio bit, or both?
tired tree
likely both since its not launching correctly
past tiger
For me, the framerate lock was happening when the game was running in fullscreen mode (I think technically it may have been "windowed fullscreen").
I got around that by forcing the game to run in windowed mode.
rose totem
I cant even seem to force fullscreen at all for the spectator view, none of the console commands seem to enforce it for me
though maybe I was using it wrong
past tiger
I may have also had trouble getting the actual fullscreen mode to work too. I don't remember now. 😕
rose totem
so in 4.23 I can cause a crash a few ways trying to force fullscreen. 1 - turn stereo off and then either setres or setfullscreenmode to force fullscreen and going back to stereo mode.... or 2 use r.setfullscreenmode on AND then hit F11. If I hit F11 while in stereo mode it looks like it tries to flash to fullscreen for the briefest of moments.
I'll try forking to a 4.24 project and see how I go
As a seperate topic.... Most of our VR projects (industrial stuff or sometime film previz stuff) definitely need to have dynamic lights. This is obviously a performance hit... its basically seems to be that as soon as we have a few dynamic lights we can say goodbye to 90fps. anyone have any tricky ideas / experience in faking dynamic lights for VR with any success.
sturdy coral
@rose totem the fix is just one line if you need to stay on 4.23
You should be able to get by with many dynamic lights, just not shadows
rose totem
@sturdy coral C++ line change? I've never recompiled any of the engine content but willing to give it a go. Just installing 4.24 if there's any issues with that i might need to stay in 4.23
sturdy coral
Yeah c++, probably worth just going to 4.24
rose totem
I'm using some experimental features of 4.23 which may be a bit broken in 4.24, hopefully not. Mostly its using actor sequences. Which are cool, but it tells me "here be dragons"
sturdy coral
Main thing is 4.24 changes vr input a good bit
But may as well transition to it now
rose totem
Hmmmm... project is likely needed next week for a tradeshow so....eek
dont suppose you can send me somewhere with that one line fix listed anywhere?

Hi there! I know you can VR-preview a non-VR project in the editor, and it works perfectly. Can you also Package that same project, to be used in VR or through a regular monitor?
real needle
hi guys, i have a weird issue.. i get these mini glitches in my game, like a twitching in the graphics ..no matter if its packaged or i play the vr preview in the editor.. i dont think it any material or anything like that im using, even in a lvl with almost nothing in it it happens. My graphics card (gtx 1080) is compatible w the headset (vive pro) but the gpu occupancy hits 100% almost all the time, i have two processors (Intel(R) Xeon(R), cpu e5-2650 v4@2.20ghz) any idea what might be causing this issue?
void raptor
@real needle did you at some point turn interleaved / asynchronous reprojection off?
tired tree
@void raptor actually that sounds like it is turned on and not hitting perf
real needle
@void raptor i did not.. where can i turn it off?
@tired tree thats what i was thinking too! how could i fix it?
tired tree
fix your performance generally?
do some profiling
right now if it is reprojecting that hard, turning off reprojection will just make it untestable
real needle
oh ok i see..so you do u think its something in the engine like some project settings or a problem related to my pc?
tired tree
its likely a problem with your project itself, an actual performance issue
you need to profile and see if you are having issues somewhere
though launching into vr preview from a blueprint graph can screw up perf royally as well sometimes
real needle
makes sense..thank u 🙂 how do i profiling? ive never done it before
void raptor
@tired tree might be... i just had the same ish symptom when i turned off AWS for profiling
@real needle

hey, I just started VR Development for Unreal with C++. I'm following the VR tutorial here but I'm having some problems: https://docs.unrealengine.com/en-US/Platforms/VR/DevelopVR/MotionController/index.html
I set up my Controllers within my Pawn. They are displayed with the Display Device Model Flag by the MotionControllerComponent, so I can see them ingame.
I set one as "Left" the other as "right". They are childs of the RootScene of my Pawn.
Now when I start the VR Preview, they are both on the ground. If i move my controllers, nothing happens.
I'm using Unreal Engine 4.24. Any idea?
I'm using Vive Controllers, tested them in VRTemplate and there they work fine.
iron zodiac
Add an input to your game, i had this issue aswell the other day
just any input, that uses the motion controller (might not even need that)
i also rebuilt the steam vr input bindings just incase
@limpid widget
limpid widget
omg, it works! Thank you so much!
I'll also report that so it can be fixed (or added somewhere)
idle osprey
That page you posted has a green Feedback button.

Did you also have the issue that the motion controllers are not in the same position as when you enter the steamvr menu through the system button?
there is a small position and rotation offset between both views, but I've set the transform of everything to 0,0,0
iron zodiac
no, but i had a custom setup

@signal pike you can try launching with -vr, but people often remove the plugin entirely

For anyone else having framerate issue with Oculus in 4.23 (capped at 70 instead of 90).. the fix is Alt+Enter to toggle fullscreen 💩

rigid bear
oohhh and i was wondering why my menu button wasnt working. it just magically fixed itself after a couple of days
quiet swan
yeah I thought I was going crazy
with the menu button
so is this it?
now how do I make the pushing down on the controller to sprint?
I see sprint there
rigid bear
i think you just have to click reload there and dont change any steamvr stuff
quiet swan
yes it works thanks
weird stuff this new steamplugin but I think in the long run its good

at least there is easy custom bindings now

@sturdy coral Alright!
rose totem
So I got my 4.23 VR project reworking in 4.24. Many headaches getting the steamvr inputs working in editor and then in a package but it seems to go looks like you need to add a line to the defaultengine.ini and then for packaging manually copy all the config files over at least that's what I had to do.
Next question though. Im now attempting to load a non VR landing level with basically just a UI and a load level button. How do I test this in editor and get the standalone game mode to do VR. I already have stereo on commands loading amd have even tried pushing custom game modes in etc but so far no dice.
quiet swan
@rose totem yeah the 4.24 update as been brutal for me to I almost got it working but I found some weirdness

Hey all,
I'm seeing a crash on game launch when -vr launch parameter is used with the vive cosmos. The crash appears to be within SteamVRRender.cpp and on the line:
// Increment swap chain index post-swap.
SwapChain->IncrementSwapChainIndex_RHIThread();
Within the function:
bool FSteamVRHMD::BridgeBaseImpl::Present(int& SyncInterval)
That said, it could easily of course be due to something else as it appears to be an invalid shared pointer, but I'm not positive.
Also I must note that I do not have this issue when I've opened the same game with the Oculus Rift S. Only the Vive Cosmos so far has demonstrated this behavior.
I should also note that I'm not doing anything custom or crazy with the rendering.
I'm linking the crash dump here as well as the requisite pdb file for opening it.
Crash dump: https://drive.google.com/file/d/1uMQx1qcNeU7zsnzGD08tnKzKb0DdZsns/view?usp=sharing

Is anyone able to check and confirm for me if it's possible to force the VR spectator view to fullscreen in 4.24? I've tried everything and it seems impossible....and once I've enable the HMD even when I go back to a first person view, disable all the HMD etc I can't get it back to fullscreen either

.... kind of got a solution myself, seems that if you're doing anything with the HMD you really need to use Set Fullscreen mode AND Apply fullscreen mode. even though non vr projects let you use r.sutfullscreenmode once the HMD takes over that doesnt seem to do anything

Why does the Scene Component attached to the Motion Controller follow one tempo late if Render Capture is enabled in VR?
This phenomenon has been discovered since 4.22.
is it unreal bug?
mellow flint
@iron zodiac thanks
iron zodiac
@simple gust I might be wrong, but I think that's because the motion controller, in order to appear to exactly match where it is in real life, is using something called low latency update

@tired tree I'm using VRExpansion plugin for my VRCharacter but trying to look at an object on a table - when I lean my head(HMD) over the table to get a closer look, the collision capsule follows and I get pushed back from the table. Is there a simple fix for this?
iron zodiac
no, the capsule will always be directly below the HMD
tired tree
@digital musk don't collide with the table? Or inset the collision, or use the WalkingModeOverride so that collision only happens when in locomotion.
there is also some lean detection in the arm IK stuff in the beta branch but its not incorporated yet.
digital musk
@tired tree Thank you very very much - I didn't think of using the walking override this way. I'm gonna try that

@iron zodiac the capsule is never "directly" below the HMD, there is a neck offset by default that is changable
but yeah there isn't any movement radius that it lets walking out of a bit

@ebon scaffold I typically dont have 2 Ue4 projects open when doing VR as it always seemed to break the steamVR side of things, but if you're opening a project to check how you did something in another project I'd expect it to not lock up 😦
I'm currently experiencing a bug in 4.24 VR projects where if I launch into a VR mode and the motion controllers are off the scene will crash as soon as I turn them on. Might be realted to me getting full screen working but not sure 😦
sturdy coral
@ebon scaffold you can make a shortcut to launch second instance with -nohmd as a workaround
This bug may mess things up but I think since it is uniting as an overlay at that point in the code it won't actually conflict with the other process: https://github.com/ValveSoftware/steamvr_unreal_plugin/issues/106

@tired tree should I then manually toggle it on and off during runtime based on movement inputs? Or does it switch between the normal collision profile and the WalkingModeOverride profile by itself if it detects lateral movement without getting movement inputs?
tired tree
@digital musk it switches automatically
if there is no locomotion then it uses the walking override
if there was some, then it switches to the normal collision profile
that way you can be blocked during smooth locomotion on something that you can walk into when not

You could use "Get HMDWorn State"

both rly helpful thank u guys 🙂
Im trying to teleport but the teleportationring istoo close to my hand, like its around it abd wont go anywhere further than that.. any ideas how to fix this?
nimble edge
Sounds like it's "detecting" the hand as the teleport location. You'll need to have the raycast(?) ignore the hand.
Anyone else have problems with "Reset Orientation and Position" behaving differently for Rift S and SteamVR?
real needle
is that a setting ?
nimble edge
Are you using the teleport provided by the VR Template?
real needle
no im using a different one.. so i found a backed up version where it still worked, imported the pawn and used the migrated pawn and asame thing

Is it looking for a Nav Mesh and can't find one?
Or any other method of finding a valid teleport location...

ahh i found it.. a huge object that had collision turned on

But yeah @daring pasture I have also not been able to get them working in my own project with new bindings.
past tiger
That's a good point BambusBo. The template does have _X and _Y for the axis mappings. I will try that for my own project.
I still haven't gotten the thumbsticks to work in the template, but I was able to get the trackpads to work by adding them to the inputs.
sturdy coral
@quiet badger yes you can just restore that removed line and it should fix
or you can look at how they changed it for 4.24 and bring that line over, I think it is a change to that same if statement
tired tree
@sturdy coral you sure it still requires X/Y now btw?
they have actual mappings that can be used to infer axis's
shouldn't require the action name to also have it
sturdy coral
@tired tree yeah pretty sure, I'm not sure why it can't be inferred from the bound keys:

I guess if you had 'MoveForward' and 'MoveRight' it would have to then pick between the two to get the name of the 2d mapping, or concatenate them and then be careful that an action with the concatenated name doesn't already exist

Has anyone been messing around with Stereo Layers? I got them working great, however for some reason they render a good margin darker than they should be. Can anyone think of any reason for this?
To confirm, this is the case either from a umg render target or from a texture input. Renders noticably darker than its umg counterpart

@carmine yoke stereo layers don't receive lighting
you are likely comparing to a widget component in the level?
those will receive lighting

it should be fairly close to what the texture actually is

having a bit of a weird issue (using 4.24.1) with playing video. i'm playing video in my game (both on a wall and on the inside of a sphere I created in blender with inverted normals). the problem is that when played natively on the quest, it's like its bumping the resolution down. lots and lots of jaggies. same video played on the quest in Gallery has no jaggies. Same game played on the quest using oculus link has no jaggies. Any suggestions? Pretty new to this and might miss something obvious. Thanks.

Simplest thing sounds like you're video file is too large? How big is it? Gallery would be heavily optimised.

does anyone know if I have to bind this in steam
I had this working perfectly in 4.23 and now the same set up doesnt work

@quiet swan you have to bind it to each controller model now, and moveforward moveright won't wor, the axis name has to end in _X and _Y now for 2d bindings

@carmine yoke let me get a screenshot. I've had it on two different videos, one 1.5gig but the other 225meg. It copies the video over to the Content\Movies folder on the Quest when it deploys. Same file that I open in Gallery that plays fine.

But I've also put it on a plane just to make sure that's not the issue, and I've had it small and giant as well with no appreciable difference
and just to repeat myself, it only does the jagged low res look when running natively, not over oculus link
quiet swan
@sturdy coral when you sau the axis name has to end in _X and _Y like in this example it should be moveforward_Y and moveright_x?
damn it I spend so much time reverse enginering a blue print to work in VR and of course they break something right when I need to display the game to people
I tried it like you said and it didnt work
sturdy coral
@quiet swan yes, _X and _Y, you have to regenerate bindings and manifest afterwards through the steamvr toolbar button
and don't bind trackpad right/left/up/down, bind trackpad X and Y

how do you properly replicate the "drop and socket" on event overlap with two client side authoritive objects in the vrexpansion plugin? i read online that there were problems replicating the weld attach in 4.22, is that still the case? is there a proper workaround?
tired tree
@rigid bear drop and socket replicates for you, and in current engine plugin the weld is handled by it as well so that should work too
the engine by itself doesn't replicate welding for some silly reason with attachments
even though it would be a 1 bit cost to do so when replicating the attachment data
pretty sure its just an oversight
its not a 4.22 thing, its engine wide since...well forever afaik
have it in my notes to submit a pull request fixing that some day, haven't gotten around to it yet
rigid bear
@tired tree when i socket something to the base gun and free grip it, the object isnt in the right place anymore on the other client(that is watching). it is in the right place and welded on the server and the holding client though. and when i let the welded-on object collide with something it spazzes out on the client that didnt do the welding. on the server it worked and the collision is connected to the basegun
tired tree
sounds like on an older version of the plugin then
I reported the weld issue hoping it would get fixed
when it wasn't I had to work around it in the plugin and fixed it
granted I don't remember if I ported that fix back as far as 4.22
rigid bear
does it only have to be done on the server only or for everybody separately?
tired tree
only on server or only on gripping client
the events replicate
I can test on simulating proxy though, its possible the attachment replication ends up overriding in that case
i'll continue in PM with you

Stupid question, but do games made with the SteamVR plugin require Steam? So, if you're making a game for the Quest, should you avoid using the SteamVR plugin?

@past tiger if you are only making it for quest (not quest link) just disblae the plugin. If you want to ship to both most of the stuff is wrapped in #if STEAMVR_SUPPORTED_PLATFORMS which should be false for android, so should just turn into a no-op

@real needle you are getting a hand from a null pawn, casting it to a pawn, and the getting the hand from that, can’t work like that
You are basically trying to cast a nonexistent hand into a hand
Do ‘get all actors of class Newpawn’, and use that to get the hand
At begin play of the level it is possible it isn’t spawned yet though too

Are there any good VR games in development on ue4 atm?

@real needle for a for loop on Out Actors, or if you know there is only one, grab first index; each actor should be the target of the get hand node

I own a PlayStation VR and I know you can use a software
called TrinusVR to use the PSVR on PC, but are there any steps to set up the PSVR to test VR games in the Unreal 4 Editor
quaint orchid
Trinus doesn't natively support motion controls, you'd also need Driver4VR running with playstation 3 eyes cameras as a tracking mechanism for them, which would cause significant roadblocks with set up and troubleshooting errors.
It's possible but easily the second least ideal setup next to mobile VR
Just the cost in software and hardware alone would be about as much as a secondhand windows mixed reality headset tbh

Oh the games I'm focusing on is just using the VR Headset only, no motion controls in the game I develop just a stander Xbox control or Keyboard.

@carmine yoke i want to have it versatile. maybe it shouldnt be attached just follow the camera

For this instance, I would still have a springarm on the HMD and you can attach/detach it as necessary
oh but if its floating you want it to face the camera too, I get you
It must be that your xyz of your vr sub actor isn't correct
like its looking down the +ve z axis or something and not the +ve x axis? or whatever find look at rotation assumes
@brisk spade Yeah I think it wants to be looking down the +ve x axis

@carmine yoke my sub is set to the position of a spring arm, that is attached to the camera

I'm thinking of buying an HTC Vive Pro, any gotchas I should be aware of, I'm currently using 4.24.1 which may not be the most stable for VR, So I've heard.
carmine yoke
@brisk spade What I mean is the actor has a set orientation when you make the actor. For example, this text render's origin is at the bottom left edge and the orientation looks down the positive x axis
carmine yoke
That's the root component right?
carmine yoke
Hmm ok

hmd doesnt know if its backwards or forward?

The HMD shouldn't matter, because its just the location you're using

Hey is there a more dynamic way to do collision for the teleport?
I'm using a giant voxel world and I can't just put a huge nav volume around it

well, i should say, not really because it is cheap

Hey everybody, I have a quick question. I make archviz projects for oculus rift, but have had a lot of clients interested in Quest (unlinked) I like how I can get instant feedback in VR by just hitting play in the editor and putting the heaset on. Is their any process to do this with Quest? I understand that I can use the link cable, but won't that just give me the Rift/Windows experience? If I want to test the project in Quest/Android mode do I have to build the whole thing and then side load it each time I want to do a test? Thanks!
carmine yoke
@void root For any functionality, I just use it with link or another headset. To see lighting/materials and things like that, I use the preview rendering level with Es3.1, its not perfect but it gets me 70% of the way there. Then lastly Launch/Make a package and look at it on Quest to make sure everything's still functional and looks good.
That's what I do personally, don't know if anyone else has a better workflow
steep kite
I'm developing for Quest using Unreal with Vulkan. Project setttings are using mobile settings. No HDR, no post-processing, forward rendering, etc.
I have a material which adds some fake lighting by calculating the distance from a flashlight object which uses a blueprint to pass the position into the material.
This material works correctly on Rift, PSVR and PC-based VR platforms. It does not work correctly on Quest.
What is happening is the light position appears in two different positions depending on the eye. In the left eye it appears that an object is lit but in the right eye it appears that the material is lit as if the object is moved a small distance to the right. This creates a mis-match between the two eyes.
The material uses an Absolute World Position node plus it does a bunch of other calculations for light direction, etc.
I suspect that the Oculus HMD code in Unreal is offsetting the meshes for the right eye differently for Quest than it does for the Rift.
If anyone has experience with this or similar issues related to Quest I would appreciate your help. Thanks!

I think Vulkan is undercooked - having a lot of issues with it myself

there actually is documentation on the website, but no its not a plugin intended for beginners
dull mulch
i mean its pretty dumb by itself that you don't have gravity and collision
void root
Is there any resources or tutorials on how to get the default rift hand and controller models into unreal? I do archviz stuff and the users/players of my projects are generally unfamiliar with the equipment. If I could show the hands and controllers in the hands like they do in the setup part of the rift that would be a huge improvement for me. I am willing to buy stuff, but am an artist, not a dev so not sure if I could build the whole system from scratch.
dull mulch
also what's archviz?

Hi. I have just enabled the Windows Mixed Reality plugin and the HMD seems to be working as normal. But when I hit play, my motion controllers are not appearing, and therefore I can just move my head around the space.
This is with 4.24.1
tired tree
@dull mulch you need to hand set it up, use one of the templates that already did it for you, or derive from a character
or use a physically simulating root
don't know why you would expect VR pawns to default have gravity and collision, when its not standard practice still

hi guys, im looking for a hand template/mesh kinda like the oculus home one , any idea where i would get smth like this ? preferable for not too pricey
karmic bay
Any AR experts in here 😛
I have a noob question related to an idea and I'm trying to see if it's something I can do before diving in further
I want to create a "game" but use a camera to track a hockey puck on the floor, and build an interactive game with a projector to practice stick handling
So I just need to know if tracking an object can be done in real time
Hopefully that makes sense.
wary charm
With the VR Template and 4.24.1, the TouchPad of the WMR Controller doesn't seem to be working.
With the 4.23 and the same VR Template, it does work. Any ideas what could be going wrong and where to get it fixed?
desert saddle
@wary charm do you have your input set to _X and _Y
if you have steamvr input thingy
Vector2 Actions - As Unreal doesn't have a concept of a Vector2 action we auto group two vector1 actions with names that end with _X and _Y. For example, to create a mapping for MoveLeft you will need a MoveLeft_X and a MoveLeft_Y that you bind to their corresponding controller axis. See the sample inputs for an example. (SteamVR Input Menu - Add Sample Inputs)
and for some reason the _X named axis needs to be on the x input of the controller
wary charm
@desert saddle I am not sure. I just noticed this SteamVR binding configuration here. Not sure if setting a binding on this page automatically adjusts it inside Unreal or do I have to export and import to Unreal somehow?
past tiger
@wary charm I had to manually add the inputs for the trackpads myself because neither the trackpads nor the thumbsticks were working. https://cdn.discordapp.com/attachments/221799478364078081/667149846066626570/unknown.png
Then at least the trackpads worked for me.
wary charm
I have a PlayerStart that is pointing towards the direction of the screen, which is where I want it to be looking at first. But whenever I press play mode or run a cooked version of the project, the camera is looking at another direction, highlighted in Red. Rotating the Capsule does not seem to fix this one. Any tips?
hallow knoll
@karmic bay You can track objects in real time through CV or other means (like SteamVR tracking with Vive Pucks). But there are limitations on how fast you can move the tracked object while keeping the tracking data accurate
For an "off the shelf" solution I'd say SteamVR tracking is the only viable option, but it might not be enough
karmic bay
Gotcha
I'm trying to make something like this https://www.youtube.com/watch?v=rgaH-5m8ETY&feature=emb_title
but in unreal so I can make multiple kinds of games. Maybe include twitch interaction. I figure if I can get the base idea working, the sky is the limit
also this would be a one off setup for myself. I'm just trying to figure out a way to track puck movement or do something with an Arduino and some sensors
This looks promising https://www.youtube.com/watch?v=WHmPvZvRyxc
mighty carbon
@hallow knoll by chance, are you aware of any ES3.1 render distance limitations in 4.24.x on Quest ? With mobile Vulkan (device) and SM5 (preview), my 10 km^2 level renders whole. However, with ES31 I get black fog that covers entire level around camera at certain distance (a way smaller than 10 km^2). That's on the device only - looks proper in preview.
hallow knoll
I'm not unfortunately. Can you repro it?
mighty carbon
I'll see if I can make a small repro project without adding that terrain into it
I kinda reproduced it with clean project, but I am gonna double check..

@past tiger I'm deploying to an Oculus Go and none of the trackpad axis bindings behave like axis bindings. I'm unable to register touch of the trackpad (not clicking, only touching) and no amount of googling has turned anything up. Do you or anyone else know what's wrong with the bindings in UE4.24.1?
tame locust
I've been testing every permutation of controls I can find for Oculus Go controller bindings and nothing except clicking in the trackpad is registering.
I'm thinking UE4.24.1 defaults to some other incorrect hardware which will not allow the bindings to function as intended unless configuration files are modified. That or this is a bug in the latest release.
sturdy canyon
@tame locust it is bugged
If you are compiling engine from source i can share my changes I made to fix it
No one cares about UE4 Go support, so i don’t think anyone ever tested it..

@sturdy canyon Thanks for the response. I had my suspicions.
I've been compiling the Oculus fork of UE4.24.1 hoping that at least was tested, but any additional material you can share will be extremely helpful.

You may have to build the UE4 project with your IDE. Alternatively, build using UnrealBuildTool with the commandline:

Anyone have any idea how to fix this or what to google?

Hey fam, why perfomance of the Render Target drops significantly if I put off my Oculus? When I put it back on it goes back to normal.
I used "r.SceneRenderTargetResizeMethod 2" console command and it works great when the headset is enabled/on the face. The moment I put it off everything lags for the monitor player.
I assume it has smth to do with rendering or game threads maybe, like the Oculus SDK reduces the rendering budget or smth when it's off. But couldn't find any answer.
P.S I also render a 3D widget for the monitor player.

I have a problem with stereo layers, If I attach it to a moveable object (like for example an Ipad style tablet) it seems to lag behind the tablet. I assume this is because its being rendered after the tablet is, on its own pass, but its really noticable. Is there anyway to get it not to lag behind or is my solution just make the screen stationary?
This post also highlights the problem - but it's strange, he says it wasn't happening on the Quest for him

Oh my bad
But yeah that's the only way pretty sure
Just make a maths expression if there isn't a ue4 node for it
eternal inlet
i might add it to a c++ bplib later down the line
also adding in a way to tell if it's on the left or the right side... the cosine rule doesnt really answer that
so by crossing vector1 with vector2 and dotting that against the plane normal, i get a sign that tells me if it's x deg to the left or the right

@uncut silo If it's local multiplayer where one is a PC and another is the Quest, why couldn't the PC act as the server and the PC user continue to do their thing. The Quest user would have their world updated from current server info when they put the headset back on

it's basically a battery saving thing. don't want to take off your headset, then have it completely drained because some app decided they wanted to keep cranking through the cpu cycles.

Is there a way to start casting my own (unknown sources) app in the Oculus Quest without using the quest menu?

Easiest way is to control it from your phone

@uncut silo The default behavior is that the game continues running when the headset is removed (as in the vanilla VR template). You would have to implement a pause if you want that.

For the past while I've been getting problems with certain screen-space draw operations in VR. It looks like the projection from world space into screen space is just failing horribly, causing things like DrawDebugString or widget components set to draw in World Space to be in the completely wrong spot, which is affected by head orientation. (As in, they fly around the world wildly as you look around trying to find them) It's making it really hard to debug stuff since being able to write debug messages to the screen is super important in VR. Is anyone else having this trouble, and is there a known fix?
tired tree
don't use screen space debugs? those are considerably worse in VR anyway than a stereo layer or actual physical display
honest imp
These aren't screen space debugs. They're world space debugs. But the game needs to project ther world location to screen space when rendering them, and it's failing to do so, so it looks like the debug messages are just at some random spot in the world that has nothing to do with where I told them to draw, and they fly around when I move my head.
tired tree
the screen space is split, its the same reason that rendering widgets directly to screen don't work right
in VR
honest imp
They used to work in 4.22 or 4.23 or thereabouts
tired tree
or why the debug messages and stat windows have been all over the place in every engine version as they keep having to correct them
honest imp
It makes sense that the screen projection stuff would break when your screen is split. But it used to work. They just stopped supporting it, or what? Has someone made a plugin or anything to fix the calcualtion to draw separately to each eye?
Debugging stuff in VR is hard enough as it is.
tired tree
which is why in game debug objects are pretty nice, drawing directly into the screen space is usually worse in all cases
there are a couple of vr debug plugins out there that offer that kind of setup
and open source code for making your own
unless you specifically want arrows or look direction or something projected
then I can see your point
honest imp
Often I just want to verify that some blueprint logic is running which relies on player interactivity. So I toss in a draw debug string to draw something over the object, and then I remove it.
But now the strings don't reliably show up since they draw god knows where due to the projection failing
mighty carbon
sooo, Epic apparently can't repro the bug I am having with the project I provided (which obviously I tested several times and the bug was there). Can someone with Quest (and UE 4.24.1) test it and see if you are getting the same issue I am getting ?

shy merlin
Yes
mighty carbon
@shy merlin do you use stock UE4's PP or rolled out your custom solution ?
shy merlin
@mighty carbon So I use some post process materials for the fog and cel-outline. Other than that, it is what is available in the mobile post processing stack. I'll link some documentation.
This shows what is available on the mobile platform.
mighty carbon
I see, cool
I was told that stock UE4's mobile post process is too heavy for mobile VR
sturdy canyon
Just clicking the Mobile HDR checkbox doubles your render costs
And each PP pass will eat up a couple ms even if you just add 1 to each pixel
Maybe not quite 2ms
so it is recommended that people not use it. But apparently it works. I'm surprised it worked at all on the Vulkan branch
shy merlin
Vulkan handles the depth calls and other passes differently than es3
Mobile hdr is essential for Vulkan
mighty carbon
I think you are misunderstanding, or they misspoke - Oculus said many many times not to use Mobile HDR
every time I report performance drop Oculus tells me to make sure that Mobile HDR is off
sturdy canyon
If it works and he can get good enough perf, cool

just skimmed through that video and nowhere in there they say Mobile HDR is essential for Vulkan

it needs to be on for developing in vulkan

I'm pretty sure that no released Quest games are using mobile HDR right now. If you can pull it off, you would have a unique look 🙂

right
there has to be games using mobile hdr

tame cypress
Is there a right way to make a VR mirror for best quality/performance? planar reflection, scene capture cube, render to texture? Currently using a 2d scene capture with an orthographic camera with flipping the texture rendering, and tex coord to size how i want, but having difficulty figuring out the material math to make it look right with all distances with the orthographic camera. Perspective cameras aren't really giving me good results because no FOVs settings make them look like a real mirror. Currently my orthographic mirror really only works from one set location, and not when i move it around. Since I'm trying to fix this, just wondering if i shouldn't be wasting my time with it, if there's a better/different way...

@tame cypress use the normal way to do it but curtail when and how its rendering based on the player

pine nimbus
Planar reflections on Oculus Quest put the framerate under even with extreme scene optimizations.
I'm quite sure if the whole scene was rendered twice or even three times it would run at frame, yet a planar reflection tanks performance. Has anyone achieved a performant true mirror on Quest / mobile VR?
woeful sundial
@odd garnet did you configure the SessionConfig in the AR project? there are settings for automatic mesh and collision generation in 4.23 and later. (Earlier version require to use a procedural mesh.) Worked on ARKit at least. ARCore is in general very broken in Unreal Engine. Development seems to have stopped. ARKit also incomplete and buggy. See bug reports for more info https://issues.unrealengine.com

real needle
Hello! Do you know how you can scale the content in AR?
When designing a full-size map ... I would like to place it on a small-sized plane ... like a board game ...
real needle
I'm new to Unreal, what kind do you see developing an AR game with Unreal? Its viable? there are implementation failures .. etc?
woeful sundial
@real needle yes if you scale down a level with "Set Level Transform", all actor positions will be scaled down, BUT the actors themselves would stay the same, so these need to scale down aswell. The scale-factor could be saved at one place (game instance or player controller), then every actor can looks it up and scale itself down in the constructor. (Easy, but Downside: unit-dependend things like physics and movement components using mass, force, velocity etc. will not all scale accordingly.)
A better method maybe would be to set "World to Meters" in the World Settings. But i did not try this yet. It does work for VR, but for AR it might not.
@real needle hurts me to say that, but Unreal is not a good choice for Mobile AR. Nothing but trouble, bugs, as usual no documentation. Much better off with Unity who care.
Unless Fortnite gets an AR mode, it will stay painfull.
You can search the forums to find out more about all the problems
real needle
I have seen the game The Machines, which is made in unreal, and looks great, it hurts to move on to Unity .. since I come from there .. xD
woeful sundial
The team behind The Machines surely had an Objective-C/iOS dev in the team to fix stuff like icloud saving. UE4 only has it's limits. Also this was ARKit 1. You could use older UE4.22, but no ARKit 3 features. Have a look at Apple's Reality Composer. AR Graphics are more efficient than UE4 on iOS!

Then maybe you advise me to use Unity for AR games .. right? 😦

The Reality Composer app from Apple uses fake ambient occlusion, scene-capture, realistic lighting, post processing to match the camera footage (bloom, motion blur, grain) and the device does not even get warm. With UE4 even newer devices get warm and throttles.
@real needle sadly, sadly, this is the current state, yes. There are no infos how this will continue, UE4.25? the roadmap on trello only says something about "Standardizing AR in UE across devices." Try it for a few days and then decide. But if you want latest features (people occlusion, ai scene understanding and cross plattform with android) i advise against UE4 😔

The idea I have is to make a shooting game .. as if it were in the first person .. Develop it as if it were for mobile, and then implement the scenario with AR on a plane and use the camera as if it were an FPS .. Would it be much problem adapting any game to AR mode?

@real needle Depends how experienced you are with Unreal and AR. If this is new to you, you will get results several times faster with Unity, as Unity provides documentation, instead of awkward live streams.
real needle
The problem is that I want to focus on AR and VR development ... and I understand that for VR it is better unreal ... but for AR it is better Unit ... xDDDD. It is difficult to decide on use a single xDD platform
woeful sundial
I know.

Ok, thank you very much for your help 🙂 I will try to continue with UE4

@real needle are you developing for Oculus Quest?
for AR you definitely might want to stay with Unity (unless you are working with Hololens 2)

I made an ARCore app in UE4 last year and it was fiiine
but epic seems to take a bit longer to get the latest AR features integrated
tired tree
@mighty carbon have you even tried to make anything AR?
woeful sundial
@sturdy canyon I have to disagree. Last ARCore update branch is 4.21. November 2018!
That is not just a bit longer
both ARKit and ARCore have quite more features since then.
ARkit 3 -> Unity SAME month, working with Apple and Google. Unreal release post claims support. But camera footage bug and only some feature supported without (as always) any documentation. (Going through blueprints and sourcecode, as if time was an endless resource...)
oh and also environment capture for lighting makes any app crash. UNUSABLE
mighty carbon
@tired tree nope, but seeing how ARCore support hasn't been updated for a long time (and new AR devices not even having UE4 SDK or integration), it's safe to say Unity would be a better choice

A look into forums, answerhub and bug reports shows the sad state of mobile AR with Unreal Engine.
spare yew
It's worth noting that while the ARCore plugin hasn't updated, the SDK has and so the updated features like realtime image tracking do work (I have tested this and actually had better results out the box with UE4 than Unity)
(I also made the mistake of assuming that ARcore plugin still being on 1.7 meant that no new features were available since then)
A fix for the aliasing of the camera image is coming in 4.24.2
hybrid plume
Hey there fellas, so for the Quest I can set CPUandGPULevels (maxed out) with a node, does anyone know how to return back to dynamic power throttling?
woeful sundial
@spare yew ok, but the problem is not about support for image tracking. Let's rather discuss problems than smooth down critique. This is no bashing, we all love Unreal. ❤️ But there are problems and we can point them out to make things better, at least i hope so.
There is more to making a full AR game than just spawning a mesh or image.
Several AR bugs marked with target fix 4.24.2 have been already been marked for 4.22 and delayed again and again. More current bugs: Camera rotation bug, cannot get video format for AR, and even starting ARCore Session bug. How to create an ARCore app if the session does not start? ARKit list goes on further. I also don't want to use Unity, it is just a fact, that it leads in this.
