Victory has a plugin to simulate keypress, and it half-works - it does generate the action tied to that key press, but it doesn't pick up the key release event

hallow knoll
#

That seems specific to your setup, that's not the case with the Action/Axis events by default

trail shale
#

I know that, it would be unreasonable for me to expect support on such a unique use case, except that I've been trying for 3 years now

hallow knoll
#

Did you see the VR Spectator Livestream I did? I showed off a hack on how you can add a menu to the spectator preview

trail shale
#

show me the link, I'm assuming it involves a scene capture and setting the spectatorscreen texture to the Render target tied to the scenecapture component

#

and basically point that at a 3D widget

hallow knoll
#

No I have a 3DWidget infront of the SceneCapture component 🤷

trail shale
#

Yes that's what I mean

#

then you get the mouse position and tick that relative to the WidgetInteraction

hallow knoll
#

Mouse X/Y, do a little transform math, and voila

trail shale
#

I'll take a look at your video, maybe there's something I'm missing

#

Someone had mentioned a way to apply the actual VR player's view to a render target as well

#

I'd like to try that and apply it to the background of that 3D widget, then I would have what appeared to be floating buttons

#

that float over the VR player's perspective

hallow knoll
#

I didn't walk it through in the video, but an example is part of the project. I was going to link that buuuuut those Forum links are broken T_T Will PM you direct downlad instead

trail shale
#

The other thing I tried was to do a simple local multiplayer listener/client setup but I am not thinking that will work unless I can make the VR one keep focus while running two instances on VR - I wasn't able to do anything with it because I was testing remotely

@hallow knoll I am working on a multiplayer Oculus Mobile app (for the App Lab) and want to create a listen server just to match up 4 people to play a simple game- It looks like I should probably use the Oculus Subsystem after reading the support page. I guess I am just trying to figure out what blueprints to make and where to put them (I think the host and join nodes go into the 3d widget interface buttons, and then I need an entitlement check I think, but still trying to figure out what to do)

hallow knoll
#

Yeah and you'd have to make everything work between host/client which would probably be a lot of work

weary swallow
#

When the Oculus Subsystem Creates a Session, does it open up a matchmaking pool that the OSS Find Matchmaking Systems can find instantly?

hallow knoll
weary swallow
#

thank you! I have been reading the page, stumbling through slowly just because it's lots of new ideas for me.

hallow knoll
#

If you haven't done multiplayer before, you're in for a ride

weary swallow
#

hahaha Aaargh!

#

aside from all the replication and RPC work, do you have any quick lookouts for a noob like me for just wanting to connect any 4 availible players to play VR horseshoes?

#

also another quick question- is there a difference between the APK file that is created by "Launch on Oculus Quest" and the APK that is produced by "Package Project for Android ASTC"?

hallow knoll
weary swallow
#

thank you!

hallow knoll
#

You can download the Collaborative Viewer Template from the Launcher if you want to look at how they did multiplayer

#

But that's a "this works"-setup. VRExpansionPlugin is doing it the right way for a game.

weary swallow
#

Thanks so much again

Is something wrong with Lighting on Oculus 4.25.4, having issues with following -

  • Piink HLOD textures after building.
  • No indirect Lighting, all the indirect surfaces are pitch black.
  • Reflection captures are messed up too.

#

Vive aciton mappings. Is there something required on the SteamVR controller binding side? For some reason I can receive input for Vive (R) Trackpad in the launcher VR template, but not in a level with a custom build. Same name in Action Mappings.

#

I been having an issue setting up a level for Architecture preview which i been doing through the game etc. I just installed it on my Quest 2 and I get the splash screen for a second then it 'loads' and the whole thing is just black and I can't see or do anything.

chilly pasture
#

have you packaged your map ?@lethal kiln

lethal kiln
#

I'm just packaing the whole thing through the android astc, is there something specific for map packing?

#

I get an OBB file with the APK

chilly pasture
#

Inside Project settings, Packaging, add your maps in the map list

#

@lethal kiln

lethal kiln
#

Yeah the same map is set for both Editor Startup Map and Default Map. Which is only map and I named it something unique to distinguish from default template name.

#

@chilly pasture

chilly pasture
#

you only have one map ?

lethal kiln
#

Yes, just an experiential kinda thing.

#

Okay it wasn't in there. thanks this might be the fix I needed.

chilly pasture
#

well, if there is just one map, then it should not be the problem, but try this and let me know, if this does not work, there might be something else going on, you can always send logs that will give more detail on that.

Usually if you have this issue, in logs it will say at some point, packagae, your map name cannot be loaded, something like that.

lethal kiln
#

Looking through the output log after launching the app on my quest gets me nothing. Still just 3 dots, and a black background. I really don't think the map is all that complex but could that be an issue?

#

@chilly pasture

chilly pasture
#

you are launching then map should not be the issue.
once launched and then you can see an apk installed in your unknown source folder inside quest, you can run it from there and while running use adb to fetch the logs and then send those logs here.

#

I don't see nay errors, I got a couple warnings about PNGs being used which I think is just for the splash screen.

Hi there, I'm having an issue where SteamVR is seemingly tracking the exact location of my motion controllers, instead of the location of my hands. When I enable the oculus plugin for ue4 (I'm using an oculus rift s), the hands track properly and the in-game hand meshes correspond to the location of my hands. However, when using steamvr, the tracking is different and instead the location of the hand meshes corresponds to the exact location of my motion controllers. This makes it so that when my hands are pointing forward, the in-game hand meshes point upwards because the motion controllers are being held upright. Is this a common occurrence? Any help is greatly appreciated.

sturdy coral
#

@warped quail which hand mesh

#

oculus hand sample or template mannequin

short laurel
#

@warped quail I often detect whether steamvr and apply an additional transform to compensate

warped quail
#

@sturdy coral I am using the ue4 vr template mannequin

#

@short laurel I tried that, but I couldn't get it working very well, especially with grabbed objects. I ended up just copying the motion controller blueprint from steam vr's sample project, and it is now working fine

lethal kiln
#

I finally did it... after cheating and looking up how to merge two levels and just merged the levels and copied them onto the tutorial level... I don't know what thing makes it work and i'll be honest I don't think I'll ever learn.

#

alright, this is driving me a bit insane. I've been trying to port a project to quest 2 for about 2 days now and everything I have tried has completely failed with next to no error logs

#

I've tried 4.25, I've tried 4.26, I spent 3 hour compiling the oculus branch of 4.26, I've tried blank projects, disabling all unneeded plugins, blank levels, everything, and upon launching the game on the headset through UE4 or installing an APK it just goes to white dots for a few seconds, and then straight back to home

#

the only two errors i have ever gotten were

5sX4aoc.png
#

and the first error vanished upon adding \oculusVR to additional asset directories to cook but the second error has been persistent

#

but no matter what it's the same thing, white dots and then back to the home screen

#

sometimes I can get the quest 2 to show me a screen with a button that says "app info" when it crashes but that just freezes my headset for a restart

#

I've tried uninstalling and reinstalling all android studio SDK's through different versions, I've tried every possible SDK and NDK number combo in the settings

#

I am just baffled as to how it somehow works for everyone else

#

I've followed every video and official tutorial I could find and searched up and tried all answers on the forums

#

I specifically thought installing the oculus branch, while painful, would atleast kind of help but it seems like it was just the biggest waste of time so far

polar valve
#

@chrome siren Have you checked logcat? I had that second error at some point but unfortunately don't remember how I fixed it. Also can you post the full log? Maybe there's something in there

#

adb logcat -s UE4 -s debug -s DEBUG

#

Also had that first error actually but fixed it some other way

#

Possibly by also removing binaries and intermediate from my engine install and doing a full engine rebuild. But if you already set it up from scratch that wouldn't do anything

Hi, i have a vr camera problem when playing as Client.
Basically I have VR setup that works fine if I play standalone or Listen Server, however if I click on play as client, the camera in VR si locked, so if I move my head, surroindings move with it. Does anyone know a solution to this? Thank you very much.

trail shale
#

So, after 3 years of trying to develop in VR - I feel like it's fair for me to think that the editor should open up the same SIZE of a VR screen , each time, instead of randomly doing it

brittle crown
#

UGH, so the learning module (4.24) has me creating a BP for the motion controller named BP_VRHAND.

#

The module uses Occulus but it is supposedly the same for Vive. When they add the motion controller they go to details -> visualization and select display model source and it automatically detects the occulus but it doesn't for the vive.

-_-

#

The input action nodes are on the VR Pawn in the 4.26 VR template map.

Also there's a surprising amount of spelling errors.

Hey guys. Using OpenXR, is there any way you can figure out the device that is actually connected? Or even just the platform? We would like to know for analytics, but also need to know it to determine the correct Eye Tracking API to use

#

Since we now want to support the Reverb G2, we have to use OpenXR instead of the WMR plugin..

#

But with OpenXR, there seems to be no way to even detect who the manufacturer of the headset is let alone the device name

sturdy coral
#

@twin heart I'm pretty sure they change the LOD amounts based on quality settings that they auto-pick when you first launch through gpu profiling

#

Unreal has a similar benchmarking thing built in

twin heart
#

@sturdy coral yes i imagine. Whats the Benchmarks name?

sturdy coral
#

@twin heart https://www.tomlooman.com/auto-detect-graphics-settings-ue4/

Tom Looman
Auto-detect Optimal Graphics Settings for Unreal – Tom Looman

Unreal Engine can auto-detect 'optimal' (graphical) settings per player based on a quick CPU and GPU benchmark. The functions are available in Blueprint to hook up into your game's options menu. Behind the scenes, the benchmark returns a performance index for CPU and GPU with a reference of 100.0 for "average good CPU/GPU". These values are then...

#

there is a command to adjust lod distances you could use based on the result of that

#

you'd probably want to know HMD refresh rate and FOV too, since that determines geometry burden

twin heart
#

Yes its a struggle, i try to get around 1.5Mil triangles and around 1000 drawcalls

#

@sturdy coral if possible

#

But for me i don’t get how much i can target for Ultra Settings... i have in my hmd rift s 5 million triangles and 2000 drawcalls and runs on 80fps when everything up. Are there games out there that have this “costs” on Ultra? Or will i create there a mess?

I dont think I would be able to test the motion controllers without hardware of my own but perhaps I could substitute mouse cursor input to set up the gameplay mechanics.

#

really weird issue here, running in VR on an Oculus Quest, getting horrendous performance when tabbed into the game (like 3 fps) but when I tab out it goes back to normal.

Also just getting unexpectedly shitty performance (20-30 fps) in a basic scene with a few trees and some grass

low bough
#

Could be a lot of things from size of textures used for the grass/trees, number of instances drawing at one time to using Mobile HDR (which will drop your fps right away by quite a bit)

#

I have to limit how much grass I have in my scene because it destroys performance

#

Are you using RenderDoc at all? It might give you some insight.

Anyone know how I could go about adding a fade to anything beyond the player when a menu spawns? I've been looking into render masking, but I'm wondering what the usual practice is for dimming or blurring a surrounding environment while an immediate object is accessed?

maiden willow
#

I could be wrong but I thought Quest 2 wasn't an option yet until 4.25.x

quiet dew
#

I too thought that but have seen it working with 4.23 so know it can be done

low bough
#

Do you have the option to compile the game engine from source code? The only reason I ask is because Oculus has their own build and its set up for quest 2.

#

I avoided doing it for a long time but ended up doing it because I ran into other issues with the normal game engine

quiet dew
#

Is that done by using GitHub? Think I read that somewhere, apologies I'm still a noob with the technical stuff.

low bough
#

It is.

#

And no apologies needed - nothing wrong with being new. I'm still figuring it all out.

#

Its a bit of a pain to learn to compile it but in the end it gives you a bit more freedom. It also can take a long time to compile depending on your computer so I tried to avoid it

#

but in the end I found it easier because they have things in there that aren't in the core version

quiet dew
#

Ahhhh OK thanks, well I'm running out of ideas to solve my issue so it surely can't hurt to try

I'm able to launch the project to my quest in UE4 but I just get a black screen (guardian boundary still appears however)

low bough
#

hmm..

quiet dew
#

Some tutorials use the android studio but when it comes to launching the .bat file I don't have the option, which I'm assuming is to do with the fact I'm using an older version of UE4.

Are you suing your own project or the sample vr project

Did you start it from the VR template?

not running mobile HDR, I'm using the VR Expansion Plugin and running on their template project so it should all be configured properly. It's not the scene i get locked at 36 FPS even in an empty scene.

that's only when it's performing at all, whenever I focus the window it acts like it's minimized. drops down to 3 FPS. I get the same performance drop when it's actually minimized, only time it runs normally is when it's on the desktop but out of focus

stat unit says it's taking 300ms GPU time when I focus the window, but stat gpu says it's taking a normal frametime in both cases.

Hi everybody, I'm using UE4.25 and been dealing with a strange bug. In the input mapping I created an "Action Mapping" named "FireWeaponButton" and choose "Vive (R) Trigger" and "Oculus Touch (R) Trigger" to trigger this "FireWeaponButton". So a player using HTC Vive controller will call this when they press trigger or a player using Oculus Touch controller will also call this when they press trigger. However when testing this out with HTC vive controller, when I press trigger the weapon simultaneously double fires (player uses 2 bullets), when I take out "Oculus Touch (R) Trigger" it uses 1 bullet. Why does pressing the Vive trigger also doubles as pressing the Oculus Touch trigger?

hey @split steeple, you were working with SteamVR plugin if I remember correctly. Sorry if this is the wrong person. I'm trying to get which input is pressed with Any Key node. But Any Key only fires if that button is set up in the bindings. This doesnt happen with OculusVR. Is there a way to get whatever pressed in SteamVR without setting it up in the binding?

#

Somehow I screwed up the VR spectator screen texture to be locked to a different render target - I've done a "find all" for the Set Spectator Screen Texture but none of the ones I removed have fixed it ( I can tell it's set to the wrong render target because it is showing pictures of assets that aren't even loaded, like it's cached in the editor) - Any other place I should look?

#

Weird - for anyone encountering this problem in the editor, you will literally have to run a command while running the game to set the spectator screen mode to something different, which I'm guessing will reinitialize the internal Render Target the editor uses (I know it's not a RT but you know what I mean, it's outputting the VR player's perspective )

#

I really hope Epic fixes it's VR editor preview tools in Unreal 5 (but I'm not holding out any hope) - really sucks to have this happen and have console commands do absolutely nothing to the preview mode

#

Right now I am forced to ALT-ENTER the window (but it doesn't want to redraw the correct resolution, it still only takes up the same size that the windowed version did) and then when I close it and run it again, for that one time only, it is full-screen like it should be )

Seems like it could be related to the hands/controllers switching - and no, I've never come across that, but I also haven't done anything resembling production development with hand tracking - just goofing around

dusky moon
#

ah no I'm not using hand tracking - just with Rift S using motion controllers ... they track just fine even after re-spawning

#

the issue which is strange is just button press

hallow knoll

that requires to toggle oculus dashboard button to re-enable it

Hey does anyone use blueprint for both VIVE & Occulus?

viscid moat
#

@hallow knoll is there any reason for the bIsTracked bool on motion controllers to still be accessible? It appears to me that it's returning true even when controllers are off, so it might be legacy? It seems to have been replaced in favor of an enum for the controller status which appears to properly say NotTracked, unless I am mistaken?

sly elk
#

@hallow knoll Have you moved over to VR stuff now?

trail shale
#

Does VR have different rules for collision because they want VR to fail?

Not trolling - I don't understand why this Last Hit Actor is NEVER any of these items - even though this motion controller CAN interact with these objects, and even the laser pointer CAN, when I override it's visibility to ensure it is on

unknown.png
hallow knoll
hallow knoll
hallow knoll
#

I always use overlap for anything attached to the motioncontrollers, especially since hit is more expensive and fires every time two primitives touch (which can be quite common since your hands shake slightly)

trail shale
#

Basically the gameplay is for firefighters to do incident command (strategic thinking of complex incidents) - so outside of the truck, I want to have the laser pointer ON - but inside, I want it OFF, (that's LS Draw Laser Pointer Bool) - So when they ARE in the Firetruck, it sets the "show pointer" (which literally is used to draw visibility of the pointer) - however, if it is pointing at one of those actors listed, it should show them

#

As far as I can tell, that second screenshot is where the relevant LastHitActor is set

trail shale
#

@hallow knoll as far as I can tell, being "inside" of one actor is making the collision system not poll again and check to see if it is colliding with one of these other actors - in fact, if I debug move my player away from that truck, it will actually interact with the items - (but oddly enough, not toggling visibility of the laser pointer)

hallow knoll
#

yeah hit is only for the immediate >|< hit, not overlap etc

trail shale
#

So my issue is I guess I have to filter out that collision channel of the Truck itself

#

The problem is sometimes I need to interact with the truck (the truck handle)

#

and I really don't want to just filter it out, it seems like a brute force way to get some functionality at the cost of future functionality later

This might sound a little odd but I'm wondering if there is easy ways to distribute a VR game/apk/experience so someone can do a really simple download or go to a website see a QR code and get a link or something for Quest.

4.26.2

viscid moat

Try 4.26.1 or a later 4.25

after adding DLSS and fixing a few things, getting 117 FPS

novel sigil
#

So does anybody now how I can size the collision for a character based on the location of the hmd irl? I have been having a lot of trouble and would like any sort of assistance I can get

neon geyser
#

What are the important metrics to profile regarding textures optimization?

#

The memory?

#

@jade axle would be best off checking performance without DLSS prior

to make sure the baseline is solid

does the quest support cloth physics?

Anyone else having problems showing a texture on the spectator screen in 4.26?

(or can test and see if it works for you?)

viscid moat

viscid moat
#

Not really sure what you're referring to?

nimble edge
#

There’s a “set spectator mode” node. If you set it to texture. Then do a set spectator texture mode and set it to any old texture: it should show that texture

#

In 4.26 I’m just getting black, instead of the set texture.

viscid moat
#

Yes, I built a camera last night and it works just fine. It uses a render target that is set up properly.

#

Call these in this order: UHeadMountedDisplayFunctionLibrary::SetSpectatorScreenMode(ESpectatorScreenMode::Texture); UHeadMountedDisplayFunctionLibrary::SetSpectatorScreenTexture(SpectatorRenderTarget);

#

Change the gama on the RT to 2.2 or else it's too dark

#

And make sure the size is correct

nimble edge
#

Hrmmm. Thanks.

#

I have it working in several projects, but it won’t work in any of my 4.26 projects

viscid moat
#

I haven't had this set up til last night so I can't speak for previous versions.

nimble edge
#

I’m setting it to a widget, instead of a RT, but no textures are working for me... so it’s not a widget problem.

viscid moat
#

Won't be able to help without code/bp screenshots really. If you follow the tut everything should just work

#

I also can't speak for 4.26.2

#

Bind things to keys so you can try them at runtime instead of prefab.

nimble edge
#

This is a simplified version of what I'm doing:

unknown.png
#

That works in my 4.25 projects. But not my 4.26 projects.

#

ooo, false. It doesn't work in THIS project....

viscid moat
#

Sounds project specific then. Not sure if there's some settings you may have opted into that are preventing it from working, but if you make a blank 4.26 project, and it works, then you have some personal digging to do.

#

Don't mean that in a bad way, just that I can't help much without source code.

nimble edge
#

Found it. OpenXR

#

OpenXR on - No texture. OpenXR off. Texture.

#

cruuud. I need OpenXR for this project.

#

Or maybe it's WMR. I'll check later today.

viscid moat
#

Glad you were able to fix it! Always the dreaded check boxes that ruin things in UE far too often lol

#

And yea, OpenXR isn't quite ready, so I'm not using it yet. Going to use it in the future when all the kinks are worked out.

nimble edge
#

Looks like it's not openXR, it's WMR.

#

As soon as I turn on the WMR plugin, or the OpenXR plugin the texture stops displaying

#

Which is no good fro me. This project is WMR only

viscid moat
#

Yikes... I have no experience with WMR unfortunately so I can't help any further. Might be better off filing a bug report somewhere to try and address it.

nimble edge
#

where do I file bugs?

#

I've never done that for UE

#

found it. I should have googled first.

jade axle
#

seems DLSS is per eye so it's running twice, still getting a minor performance boost from it though

jade axle
#

is there any way for it to like, not do that? I would have figured it would run both eyes as one image and upscale the whole thing. Doing it this way seems slower.

How do VR games move a character rigs hands then?

obtuse spruce
#

@neon geyser I've done some software occlusion. Have you set r.SO.VisualizeBuffer to 1 while using the mobile preview renderer to see it's working? Occluders show up as white in the visual

#

You can also use stat softwareocclusion to get hard data on what it's doing

#

@tacit solstice That seems pretty simple. If all you need VR-wise is a pawn with a camera following the HMD, the VR template project has you covered

low bough
#

You can do some limited bone transformations in an animation blueprint but if you are just trying to have hands that are attached to the motion controllers, its better to break the model up into separate body and hand/arm models.

#

You can also add arm/elbow/hand movement if you want full arms using IK in the animation blueprint.

If you have a graphics card that can support the rift you can use oculus link to view your Unreal project through VR Preview. You need the oculus software and plugins installed.

im getting some weird behavior while using vr headset with skylight, left eye shows skylight but also has some image overlayed and right eye does not show skylight. what should i look into?

hallow knoll
#

@nimble edge Spectator screen in 4.26 with OpenXR doesn't work - fixed in 4.27

#

@jade axle Each eye is a separate camera and post-effects like that need to be processed for each eye. Nvidia might be able share data between the cameras and do DLSS but not currently. Remember that only tensor cores can use DLSS so it limits your market if it only performs with DLSS on.

uneven python
#

so... no one has any problems with skylight flickering? also, do volumetric clouds appear ok in both eyes?

wheat holly

I believe I've heard people in here before 'complaining' about the clouds not working, not sure about the skylight though.

low bough

I haven't had any issues with skylight. I have it set to static though and mainly use it for baking. I'm also using the Oculus build of 4.26 so I wonder if something from the Epic build wasn't merged into it.

Is there a trick to getting this audio device to default to NOT muted? Valve Index - I need to find a way to activate this from the engine automatically if possible - because I'm recording audio and it won't work if it is muted

I don't think my mic on the Vive is automatically muted

I know that's not helpful, but I would check to see if it's a Windows setting vs an engine setting.

I know you can turn the mic on via cpp or bp, as I had a hell of a time figuring out how to get the submix to record properly without getting audio feedback.

I would imagine turning the mic on via the engine should default to being unmuted? That would be logical.

solve 3d position and rotation from fake mediapipe depth, then you have a normalized looking straight face

from there is just record min max a few times and train from that

For more than 2-4 player setup, take a look at VR Expansion Plugin. It comes with exposed data frequency parameters and client side interpolation - which allows for less bandwidth-intensive transform replication

Anyone got a good method of making sure when you push forwards the vr character will always walk in the forward vector of the the mesh or an arrow ref like I made .

I'm having a bit of an issue, I'm using an Oculus Rift S, and when I go into VR Preview, The headset works just fine, but my controllers aren't appearing/tracking. The only thing that works is when i press the menu on them it does bring up the menu. I've tested the controllers in other games and they work just fine. Its only in UE's VR Preview that they don't show up at all. Anyone by chance have a fix?

hallow knoll
flat goblet

I've tried both. The project I originally was working on was working and then I'm not sure what happened but it stopped.

#

Thats good to know about the blank project though! As that would explain why it isn't working.

hallow knoll
#

Working with VR is somewhat notorious of occasionally having things not working - whether performance related, black screen in the HMD, or controllers not working. If you're testing with a newly created VR Template and it's not working, a PC restart is my go-to

sturdy coral
#

@ashen dome you can set bAbsoluteRotation on scene components

#

and then location can be in relative space and rotation in world space

#

there are some tricky things with characters and control rotation because rotation is applied pre-tick during input handling, in APlayerController::PlayerTick

flat goblet
#

@hallow knoll I'll give that a go and hope for the best.

Hi, Im making a Vr game, where players character moves a lot in a space (flying). Now I have a question regarding optimalization. When im high and I see whole world and I have certain speed, FPS drops. Im thinking the reason is that lot of pixels are updating so bigger the speed and bigger the world I currently see causes FPS drop. Now im not sure, so can anybody tell me if Im right with my assumptions?

  1. If i correctly set cull distance and LODS, game will be more optimized, since player doesnt see everything
  2. If I dont look somewhere, so pixels are not updating on camera, unreal does not calculate this by default (I dont know if its true or not)
  3. I want to limit peripheral vision based on speed, that way I dont see whole world just. Does limiting peripheral vision based on speed increases optimalization and how can I achieve it?

Thank you very much for your help.

Anyone ever had the problem where changing levels (using Open Level node) in a packaged build changes the lighting? This strangely only happens in a built project but not when changing levels in editor. Also, the lighting is normal when starting up the packaged build (this is the default map) but changes when the map is reloaded (opening the same level) or changed to another. It appears to be turning off the Skylight, because deleting it in editor and using PIE makes it look identical to this.

After changing levels (to the same one):

Quick question. Does anyone have any particular preference for adding motion controllers to a character as individual components or separate actors?

wheat holly
#

Why would you make them completely separate actors?

ember pumice
#

I prefer separate actors as it's more flexible and not tied into the character class

orchid oak
#

Thats reasonable

delicate isle
#

I've been using components for my motion controllers up until now and was considering changing to actors. However, does this mean that both actors will then need to replicate independently of the pawn and is that going to be a future performance issue?

sturdy coral
#

I put them as part of the player controller and attach to character

#

So you are interacting with menu, or interactive grab able ui stuff it doesn't break down if pawn is killed

#

No player controller on non-owning clients, so I replicate positions for them separately though

frigid osprey
#

I started putting my game under the "performance" microscope trying to sort out what was the source of 50FPS.

#

I have remove everything except controllers and a skybox

#

The controllers are have 500 vertices and are mapped to an 8x8 pixel texture with 1 UV slot to eliminate that as a culprit

#

with controllers alone it runs 90FPS

#

I have adjusted the default skydome material to have no textures during they day.

#

I have remapped to the interior of a cube

#

when the cube is on screen without the controllers it is 90FPS

#

as soon as the controllers get in front of the skybox it drops to 50FPS

#

do other people have this problem with skyboxes/skydomes? Kinda at a loss of what to do

trail shale
#

so how is it being called, or maybe it first checks the key event then looks for the event tied to it?

#

AH

#

thank you for explaiining that

daring pasture
#

Had that happen once before as well on an input that wasnt called. Same thing I had a deprecated binding set. Probably steamvr's fault, but regardless should solve it

trail shale
#

Thanks man, if this works I'll owe you a drink

daring pasture
#

Haha, no thanks happy to help.

trail shale
daring pasture
#

Should just be able to regenerate the bindings and manifest. Do you have the steamvr input button enabled on your toolbar?

#

Sometimes it just wont work for me, so I have to restart steam vr. Never had to restart the editor though.

trail shale
north tapir
# trail shale These maybe?

yea they are deprecated. Basically, if it has _ in the name its highly likely its depretaced And as someone else mentioned, its SteamVR's fault. This doesnt cause issue on Oculus

daring pasture
trail shale
#

what's a good way to test it?

#

Because I can't get the grip to fire, fuck I hate steam vr/Unreal's implementation

daring pasture
#

Did you generate the bindings and all using the steamvr button?

trail shale
#

I did all of those buttons using Steam VR

#

Just do these all in the order they appear?

daring pasture
#

These?

trail shale
#

yes

#

I change my bindings in project settings then start at the top and do all those regens

#

my default input isn't updating

daring pasture
#

They should just work for the most part then. You may need to bind directly in steam using the dashboard

trail shale
#

and I'm doing this right?

unknown.png
daring pasture
#

I dont know if theres a specific order, but yeah i do the same thing

trail shale
#

the default input says in windows it is being modified but adding ANYTHING to it I can't find it changing

daring pasture
#

There should be a steamvr input folder generated i believe. Contains jsons for each controller type

trail shale
#

Why the fuck were they all WRITE PROTECTED

#

I can't get the trackpad to work - the button you actually press down - it's this one right?

unknown.png
sturdy coral
#

pretty sure that's it, there is a separate touched one for when it is touched

trail shale
#

Why doesn't these events UPDATE

#

Literally killing myself trying to save lives and this shoudln't be what stops me

daring pasture
#

In steam vr edit the bindings. They may need to be specifically set to click, touch, ect...

trail shale
#

Why doesn't Epic with it's 15 billion dollars have a write check to make sure the bindings were actually written to file instead of just allowing windows to do it's read only bullshit - this seems to be the problem - it is showing the bindings listed in the project settings but they don't match what's in the json file, until I set it to writable

#

this is killing me

Can you not change them in steamvr directly using the dashboard while in preview?

trail shale
#

no

#

they don't appear

mighty carbon
#

folks, do you recall how to make UE4 launch Oculus instead of Steam on start-up ?

sturdy coral
#

@trail shale why do you have stuff read-only? because of source control?

#

to change them from steamvr you have too turn on a developer option

#

I think you have to have this on:

#

or that may just be for displaying the input debug overlay, I can't remember

#

but there should be an option to export back to original file once you have one of the right settings

#

unfortunately unreal's json generation is done differently than steamvrs and so you can't diff the files, it is all out of order and formatted differently

Hi,
I’m using UE4.24 and I packaged my game to steam. Whenever I try to play it using Vive or Index, the game crashes in the beginning and saying controllers not detected.

When trying to play it using Rift it worked fine.

I have deleted the steam plugin and then added it back (because my game intended to be on Oculus store only)

I'm assuming it's read only because of source control but what keeps throwing me off is the parts that I have checked out I'm guessing now are not the actual files that unreal is trying to write the new binds to - the idea was to keep the various input files more or less checked out all the time but every once in awhile submitting aversion and then immediately checking it out again - I'm starting to lean heavily towards the actual issue being when I switch to a new device I haven't yet checked out the proper Json file

hello, I just noticed that on a project I have based on the VR Template, my VR hands have their rotation offset when on SteamVR while everything is perfect for OculusVR. Is it normal or did I messed up something without noticing?

#

@sturdy timber I have the same issue. I’m not sure but I think it’s because steam vr tracks a different point on the hands. Oculus gives you the wrist position while steam vr gives you the palm location

sturdy timber
#

I see! thanks 🙂 now I just need to figure out if it's a problem or not 🤔

north tapir
sturdy timber
#

Ok thanks! so basically an offset must be set for each platform ?

#

I mean, each combo headset/platform

sturdy coral
tired tree
#

@sturdy coral @sturdy timber with every controller in OpenXR there are multiple poses, but the "default" pose is the center of the IRL palm facing inward for the tracked location. When engine is fully openXR this will just solve itself.

tired tree
#

its around 30 from vive wands difference

delicate isle
#

I was surprised the other day to find that SteamVR provides a full hand pose with animations when holding the controller. My hand tracking/controller tracking code thought I was using hand tracking and animated the hands which was awesome

tired tree
#

I have a full suite of offsets per controller that aligns them

delicate isle
#

@tired tree Are you the author of VRExpansionPlugin?

tired tree
#

but throwing that all away in 4.28 or ue5, whenever openXR is the default

#

yes

delicate isle
#

Just wanted to say thanks to you - your plugin is amazing

tired tree
#

you are using it or referencing it? you said you were making a template

delicate isle
#

Making a template project for my VR course

tired tree
#

ah

delicate isle
#

I've been using it to handle gripping and replication

tired tree
#

it has controller profiles

#

you can use them to align those controllers

#

and solve most of your problems

delicate isle
#

Just spent the last few months changing everything over to OpenXR

tired tree
#

mmmm

#

openXR isn't entirely ready

delicate isle
#

I'll have to take a look - I found the controller profile option earlier but didn't look deeply enough into it

#

I have hand tracking working on the Quest and Hololens right now

#

Made a pinching system that tracks the pinch location and passes it as a pivot to the grip interface

#

The only thing I'm missing in OpenXR right now is the Oculus hand tracking cursor pose

#

Just trying to make sure I'm ahead of the curve for transitioning to OpenXR rather than having to deal with it later

#

@tired tree Do the controller profiles offset the whole grip motion controller's transform? I currently have static/skeletal meshes attached to the motion controller to represent the hands

tired tree
#

yes

#

on the tracking side

#

to align to where the hands would be

#

essentially works like openXR will

#

lets you offset tracking to a palm position

delicate isle
#

Just found the controller profile option now - do I have to set up new ones for each controller?

tired tree
#

the template has a bunch already defined

#

though since you already have a gripping system setup

#

might be easier to start from scratch

delicate isle
#

Yeah

tired tree
#

whatever your dev controller was is the base, then you assign offsets to align all other controllers to that one

delicate isle
#

I'm waiting for XR_MSFT_controller_model to get picked up by the main OpenXR spec

#

Will just have to rock offsets in the meantime but that's fine

#

My goal is to give my students a template that has controllers/handtracking, gripping, and locomotion (teleport and free movement) already implemented so they can focus on making VR content without reinventing the wheel

tired tree
#

sounds cool

delicate isle
#

Oh, and they're developing in a Mac lab sigh

You should be utilizing the hit actor component out node

I'm not a fan of vibrating controllers anyways, and I believe it pertains to that function

On a lighter note, can I pick your brain again, with some ACTUAL blueprinting this time? I have a scene with some blocks to climb, but my player isn't "ungrabbing" my blocks when I let go, and I can't "re-grab" a block I've already "grabbed"

Ironically, my brain sees the blueprint layout the same way a coder sees code, although I know 0% C#/C+(+) at all.

#

@eager sunthat's a very nice tutorial, good choice! 😉

#

At 16:47, after the line trace, we set up the condition for falling. As you can see it is connected to the false output of the Branch node. Make sure you didn't connect it to the True output.

#

Also double check all the booleans at 13:56 to make sure the true/false values are set exactly like shown in the tutorial

#

At the beginning it is normal to mix things up and perhaps get confused with what does what. Eventually you will develop an intuition for it.

Bend your knees/jump 😛

next aspen
#

ha. But like fr.

eager sun
#

No. As in the game Blade & Sorcery among many others, you calibrate the height before you begin playing so the player is drawn at your height so everything matches

#

Otherwise you might have lanky alien garbage scoops for arms.

The thing is my game revolves around picking up small things on the ground so if youre standing up its a lot to bend down. I want to make the game accessable.

haha, no thats what I want to avoid.

By repeatedly forcing the user to stoop?

I fail to see your logic, but continue.

next aspen
#

well if I can make the player shorter you wouldnt have to bend down as much/at all.

🐌

#

But then the player would feel very short no matter their height, making it a cat simulator.

#gladimnotshort

next aspen
#

eh kinda? I think making it adjustable, maybe even on the fly, might be good. Then youd be like a smol flying robot.

What exactly are we picking up? Part of breaking a VR experience is having to do real-world painful bending during "VR happy time"

Some gummy bears. My concept is that youre defending... something? Im still not 100% sure but I guess ill go with a honey pot. Anyway, the idea is you pick them up, and throw them at other gummy bears so they go flying.

they walk around, that would be... strange. But also not what im making the game about.

eager sun
#

Well, Doctor Seuss would be proud.

#

Perhaps pick them up with a vacuum gun?

#

then shoot them!

#

I would get annoyed with tapping my controller on the ground picking them up tbh

#

It's already cracked from the death of my lamp

next aspen
#

one idea ive had is to have multiple enemies that work to change how you interact with other enemies. So I might make an enemy a vaccum that picks them up easier.
But to your tapping the ground point, they are big enough you dont have to get your controller right next to the ground, you have about a foot and a half of clearance I think.

#

But also making the player shorter would help that.

#

@eager sun you know how to help or nah?

eager sun
#

Not really in this scenario, sorry

#

I only know that mine always behaves as I described.

next aspen
#

figured it out. I actually found it a while ago, there's a part in the code where it initalises the height of the HMD and you can change that from "floor level" to "eye level" but I was editing the wrong thing.

sturdy coral
#

@next aspen most games have settled on some telekenesis (rec room, alyx (more extreme than you may want), etc.)

definitely don't go for precise pickup of floor objects because a good portion of users will have their floor misconfigured by +-6inches

I'm having a rough time. I finally remembered that perhaps someone here in discord could help. I am trying to package the simplest VR app and get it installed locally on my Oculus Quest 1. After three days of dependancy hell in Java, Andriod, deleting build folder, intermediate folders, updating and downgrading java versions, upgrading, uninstalling an d downgrading gradle i've finally conceeded defeat. Frustratingly, just a day before all this i was able to package just fine, but i was having issues with the 'keystore format' that the keytool application was generating as per instructions on the u nreal website.

Now i've given up, i just want to create a new VR project using the default template, and publish that with a local key or, uploading to oculus to publish to 'app-lab'.
Just now, the JAVA, andriod & gradle bullshit seems to have... desisted momentarily, and i'm back to this error upon packaging my andriod package:

com.android.ide.common.signing.KeytoolException: Failed to read key MyKey from store "C:\Users\timothy\Documents\xx_teststuff\asshole\Intermediate\Android\armv7\private_key.pepk": Invalid keystore format

This keystore "private_key.pepk" is my latest attempt, after being told that the keytool app wasn't generating the latest acceptible security standard. I managed to get this keystore by opening the Andriod studio app and creating it from there and placing it in the appropriate place in my project.

Could anyone shed some light upon my latest issue?

I should mention that i'm a complete noob at the security signing and packaging and publishing stuff. (That's actually why i'm trying to practice it)

# oak pawn Any folks here have specific recommendations for a headset for development in UE...

I've had quest 2 and Rift. I really don't think there is a real difference between the two of them visually wise to someone who isn't really looking for the detail etc. I'd recommend the Quest 2 for the wireless capability especially since the CV1 isn't available anymore. But I think an Oculus headset has its advantages because they're the biggest market share, you can use the Oculus headset with Steam VR pretty easily, While I think Index controllers are pretty important for the future etc I don't think buying an index and developing specifically for those controllers has enough of a market to be worth it.

Of course I've never used any other headsets. But I like the Quest 2, I don't enjoy the facebook part but it's fine.

Alright this is a very annoying process I did it successfully the other week basically what I did was follow a video which I'll link below. You essentially will do a command line and just make a really simple alias etc. From there you go to the Keystore settings in the project settings insert what you did before and then try to package it.

Then just drag the keystore file from the directory into the project folder and it'll work there.

Hope everyone's doing well. Thought I'd post this here for those that might be interested. My latest tutorial premiers over on YouTube in 30mins. Showing how to setup Half-Life Alyx movement system using Blueprints. The video itself includes extras such as having to physically crouch bellow objects to get past, stop the player going through wall, Jump, Snap Turn, sprinting and Room scale movement. So there is a lot to cover in this one. This video was made possible with help from @idle osprey who was able to figure out the crouch, snap turn, and room scale fixes required for this all to work. I hope you all enjoy it.

Hello, hope you’re doing well! I’m Gabe Mukobi on behalf of StanfordXR (Stanford University's virtual/augmented reality student org), and I wanted to let you know about Redefining Reality, our annual VR/AR Conference happening soon! On Saturday, May 22nd at 10 AM PT, we’ll have an exciting day full of speakers, panels, networking, and socials. We’ve invited numerous speakers and industry leaders at companies such as Facebook, Unity, Epic Games, HaptX, and many more to discuss the exciting future of XR.

Historically, our conference was held in person and has attracted 400+ attendees including professionals, researchers, students, and the general public. This year, we’re moving to an online format, which means we are able to invite anyone with access to an internet connection! We are hoping you would be willing to share this free event with people in your organization and anyone else who may be interested. In these difficult times, our goal for this conference is to bring together our communities to learn, inspire, and encourage all things XR and have fun while doing it 🙂

The speakers and panels will be held on zoom and we will transition into a social/networking event in VR through VRChat (connect via VR headset or via flatscreen if you don't have a headset).

You can RSVP and find the full details of our event including speakers, panels, and socials at our website: RedefiningXR.com

If you have any additional questions or concerns please reach out to me or email admin@stanfordxr.edu. We hope to see some of you there!

What's the simplest way to determine if a motion controller is moving? am I just ticking it's possition and checking to see if it's more or less the same (to that realistic margin?)

sand abyss
#

question, whats the common way to setup a VR character? currently im using a character for the base class and have its hierarchy as

capsule:
  vr component (scene component)
    CameraComponent
  CharacterMesh
  Right/Left Motion Controller Component

so i can use the character movement component for moving around the world along with replication and interpolation without creating my own system. everything currently is working fine except for room scale as i can walk out of my capsule which is obviously a problem

maiden willow
#

maybe 6 or 7 🙂

sand abyss
#

well i completely overlooked that lol

#

thank nyou

trail shale
#

Ugh, there's no rhyme or reason why new binds added to input don't seem to update - restarting editor, restarting stream VR, the rebuilding the action - i've checked the json files and those new input events are added - the blueprint in question has input and breaks fire on the other keys there - this is a brand new input action so I can't see the inptu being consumed by anything else (i'm not sure how the input stack handles the same key tied to different input actions)

sand abyss
#

well thats nearly the same setup i have now lol as that of his video

maiden willow
#

Did it help you out though?

sand abyss
#

negative as it doesnt help with roomscale. the current issue i have now is since the capsule is the root and the camera is the child, when you walk around (lets say i walk left 4 feet) i am then outside of the capsule which is whats being used for the character movement component. need to figure out some way to keep them together. changing the root to the scene component with a capsule as a child of the camera doesnt work either as the character movement component just moves the capsule and not the entire actor (same deal if you set the updated component in the character movement component to be the root scene component)

i see their working on a new VR template for 4.27 so hopefully that will come soon, i didnt see it in the dev branch yet

#

well one thing i didnt try was updating the x/y position of the capsule to match that of the camera within a tolerance and see if that helps it track together

trail shale
#

Are the InputAction FaceButtons now deprecated?

tired tree
#

@sand abyss the new template doesn't have anything like that in it

#

and for syncing you would roll back the HMDs relative offset and apply it to the characters movement

#

generally for that to be networked you'd have to do it in line with the character movement components saved moves

trail shale
#

Can you not have the same key tied to different events in this? I assume that you can be just you need to realize which one will first consume input? I am running into problems and I suspect this is happening internally, because I'm not even calling these action events anywhere

tired tree
#

by either directly injecting the offset, or applying movement input that relates to it

#

my two vr character classes take two different methods, one locking the camera in XY and moving the character with the hmds movements, and the other entirely decoupling the capsules location from the actor and literally moving it with the HMD. There are blueprint solutions as well by moving the camera root inversely to the cameras relative position.

trail shale
#

sorry didn't realize this didn't come through

I can't for the life of me get any of these events to fire

They are all getting updated here so I'm not sure what is happening -

Unless there's some order if I missing here, I think I'm going to lose my mind soon

unknown.png
#

It's okay to have multiple entries in this right? jesus this is impossible to iterate on, there's no rhyme or reason that I can figure out

#

Can ANYONE please please please explain this to me, why is this event I've made NOT firing, when the key works with other events?

unknown.png
maiden willow
trail shale
#

Why does this one work

unknown.png
#

I can literally restart someone's heart but I can't make a goddamn action binding work like I want to

#

If it were consuming input, the bottom event should still fire if I remove the top one from the blueprint

#

and if they have the same key binding to their action inputs, it can't be that one other blueprint is consuming that key for one action event but not for the other - they use the SAME key bind

#

Why did THIS happen??????? I'm using the Valve Index -

#

WHY DOES THE EDITOR THINK I'M USING THE VIVE?

tired tree
#

it doesn't matter

#

it throws any key from that action

#

the openXR like action system doesn't actually care what button triggered it

#

you can't rely on that

#

even more so since end users can rebind keys on the runtime side, so all of those faux "keys" in engine are meaning less for checking against

#

they are just used for the default manifest generation

trail shale
# tired tree it doesn't matter

Can I not have the same hardware keyed tied to multiple events? I can make it work just by using the action event that worked but I'm worried that there is something fundamental about the way the input handles VR (particularly steam vr)

tired tree
#

@trail shale you can't really with vr buttons

#

if you have trigger on two actions at once it can throw other actions

#

its a bug / limit of how they jury rigged the new input methodology in

#

which should be getting an overhaul

trail shale
#

It's so confusing to figure out what is what

#

your advice is just delete the ones that don't work and stick to the ones that do?

No dude, I appreciate it, I at least know I'm not crazy - if you get bored feel free to look, maybe there's something obvious I'm missing - It may be a limitation of the current implementation that I wasn't aware of, that's exactly why I asked

My tutorial shows how to implement it and make the capsule follow the players head so room scale works. I recommend checking the time stamps.

@dreamy ivy i probably overlooked that from skimming through it so ill rewatch it again. ended up getting it working by setting location and offsetting the VRComponent back, now just have to figure out some form of replication for this movement

void AVRTestCharacter::Tick(float DeltaSeconds)
{
    Super::Tick(DeltaSeconds);
    TickTimer += 1.0f * DeltaSeconds;
    if (TickTimer > 0.01f && !HasAuthority())
    {
        Server_UpdateHands(LeftControllerComponent->GetComponentTransform(), RightControllerComponent->GetComponentTransform());
        TickTimer = 0.0f;
    }

    FVector CameraLocation = CameraComponent->GetComponentLocation();
    FVector VRCompLocation = VRComponent->GetComponentLocation();
    FVector CurrentLocation = GetActorLocation();
    CurrentLocation.X = CameraLocation.X;
    CurrentLocation.Y = CameraLocation.Y;
    SetActorLocation(CurrentLocation);

    VRComponent->SetWorldLocation(VRCompLocation);

    CameraLocation = CameraComponent->GetComponentLocation();
    FVector ModifiedCameraLocation = CameraLocation;
    ModifiedCameraLocation.Z -= 170.0f;
    ModifiedCameraLocation.X -= 12.0f;
    FRotator Rotation = FRotator(0.0f, CameraComponent->GetComponentRotation().Yaw - 90.0f, 0.0f);    
    GetMesh()->SetWorldLocationAndRotation(ModifiedCameraLocation, Rotation);

"now just have to figure out some form of replication for this movement". might try and switch to addmovementinput

just sending the offsets to the server won't be sync'd with the character movement buffer

#

yeah you need to inject it as part of the movement process

#

if you are in 4.26 that is fairly easy now

sand abyss
#

what changed in 4.26?

tired tree
#

they have an overridable network archive stream now

#

you can pass any data into it

#

a lot easier than overriding the movement rpcs

sand abyss
#

how do you do that?

tired tree
#

no docs on it yet, since its new

but it involves overriding a network data container and passing in the new subclass in a virtual override

#

/** Default client to server move RPC data container. Can be bypassed via SetNetworkMoveDataContainer(). */
FVRCharacterNetworkMoveDataContainer VRNetworkMoveDataContainer;
FVRCharacterMoveResponseDataContainer VRMoveResponseDataContainer;

#

the section around ServerMove_PerformMovement

is where its using the new overrides

@tired tree yea im just saying screw it for the time being, i read through the code and it made some sense. for now ill be using your plugin 🙂 btw i noticed when i create a blueprint class off of the VRCharacter i have issues with the camera being in the floor upon spawning, but if i create a c++ class derived from VRCharacter and then create a child BP class from that its fine

isnt floor for steam vr? im on the vive and tried all the options with the same result

yes it is

that should work though

thats all that the template does is bp subclass the vrchar

also that is no literal difference from you subclassing it in c++ and then bp

thats what made 0 sense because there is no change. either way i needed to make a c++ class for it so its all good

This is slightly off-topic, but my Quest 2 constantly disconnects / reconnects to my PC while I'm using it, while it's plugged into my desktop (and therefore makes Oculus Link unusable).

You need your Oculus account to have developer mode enabled, and then also enable developer mode in the headset. After you've installed UE4 you also need to follow the directions for installing the Android stuff (found on Oculus developer websites). Then you need to have the Oculus desktop app installed and connected to your headset prior to launching your UE4 project

#

There are several tutorials you can find on Youtube though that walk you through the process

@fringe blaze there used to be a way, the oculus hand sample used it I think, you can look through the blueprint there

and these values are type boolean and are set to true when you pickup the item and to false when you drop it, so function grab actor and drop

the problem is these values keep reseting or so it seems as if i put a print string in the beginning that prints the falue of the variable it goes false all the time and when i pickup the item its false, true, false, true all the time

We use it because our game relies heavily on dynamic shadows and ssao

Technically on forward you only need to do a single pass for many things

I know how to set up the animation, if I know what I am looking for. I just figured out that the pawn is not using the HandMesh in the Pawn. It gets turned off or deleted, and replaced with the GraspingHand. I still see the HandState with the Enums I created in the Pawn BP.

This didn't work. I tried several areas, and many at the same time. I tried block all the areas in the pawn, and only got results when I started blockign things in the GraspingHand BP. This is a problem for me, since the Grasping hand has only one solid row of contacts. The right hand components can be dragged out, but during the construction script, it creates a left hand, and also adds sufix to each name. I have not done this type of search before.

The Oculus button should be straightforward. It's either going to be called A or Primary (I don't have Unreal open in front of me). Choose the right touch controller, primary button.

What's the best way to lock the player's camera into a fixed position in vr? We're looking at having a first person view while flying a vehicle (no cockpit, think of it like first person drone racing) and we'd like the HMD to be totally locked, just like it would in FPV drone racing. So turning their head would just have the view follow them and not rotate the camera on the pawn.

you could try to uncheck "lock camera to hmd" on the camera. Locking the camera will cause a hell lot of motion sickness though

@mystic tinsel Instead of locking the headset, I would recommend keeping it free, and then have some UI or other elements near to the user sp they can use them as a point of reference when physically moving their head around
