Good to inow

#

Know

sturdy coral May 21, 2020, 12:11 AM

#

and that should tell you the per-eye resolution there too and be the same as UE4 uses

eternal inlet May 21, 2020, 12:11 AM

#

Yeah so mine was set to 106

sturdy coral May 21, 2020, 12:11 AM

#

unless you change pixel density in ue4 from 1.0

eternal inlet May 21, 2020, 12:11 AM

#

I keep it at 1

#

Some profiling tomorrow will hopefully tell what the problem is

sturdy coral May 21, 2020, 12:12 AM

#

yeah, just make sure what you are comparing from vive is same size when you multiply WxH

#

I don't know if they remember your manual setting per device, but if not 106 might have been your vive selected resolution and be too high for index or something

eternal inlet May 21, 2020, 12:12 AM

#

Yeah i’ll try

#

My vive is 142%

sturdy coral May 21, 2020, 2:47 AM

#

@eternal inlet I think the percentage is the total pixel number and not linear dimension number, so 142% on vive would be much less than 106 on index

#

index has 77% more pixels than vive, so vive at 177 should equal pixel count of render target of index at 100, but that also depends a bit on much much more 100% is than the screen pixels

#

it can vary by HMD because of the lens warp, more extreme warps need more to hit ideal res

#

and then WMR threw out all the rules and just chose a 100% to equal the same pixel count as vive 100%..

#

just try to compare using render targets that have the same pixel count by multipling width and height and make sure the result is roughly equal between headsets (auto res should pick a multiplier that is, but may have some other heuristics based on FOV for estimating geometry burden, I'm not sure)

quiet vector May 21, 2020, 3:30 AM

#

man isn't vr dev fun?

knotty tusk May 21, 2020, 7:40 AM

#

Does anyone know how i can detect if my games launched in VR or window mode? im trying to render a different HUD depending on if your in the vr headset or not

tired tree May 21, 2020, 1:16 PM

#

@knotty tusk GetHeadMountedDisplayEnabled and GetHeadMountedDisplayConnected are supposed to handle that.

They have had periods of not working correctly, haven't tested in awhile.

knotty tusk May 21, 2020, 1:18 PM

#

are those blueprint actions?

#

only i cant seem to find them

tired tree May 21, 2020, 1:58 PM

#

They are, under headmounted display library, can access in c++ too

celest basin May 21, 2020, 2:44 PM

#

why does RTX kill VR?

#

60 fps @2560, 5 in vive

#

(on corsair with 2080ti)

eternal inlet May 21, 2020, 2:53 PM

#

@sturdy coral about checking how much that's getting rendered. Do you happen to know if there's a stat cmd or similar that will dump what resolutions the rendered rendertargets are at?

quiet vector May 21, 2020, 2:58 PM

#

jonas did you have an oculus or vive before the index?

#

sorry that is totally unrelated to your question

#

curious how index compares to other headsets, especially in terms of input mapping

eternal inlet May 21, 2020, 3:01 PM

#

@quiet vector i still have my vive, and still trying to get an impression of the quality difference, tbh, i haven't used the index much yet, because im stuck building levels atm.

#

but my initial impression, is that it looks much more smooth, somewhat darker in the colors, the audio is amazing, though i usally don't use it, i must say, after having tried the headphones, i feel like using them more when i play alone

#

i've had the knuckles for a while before i got the index, so they're not really new, but about input mappings, well... i actually still have that on my todo list to sort out the mappings for my game

quiet vector May 21, 2020, 3:02 PM

#

what is the alternative to not using the headphones?

tired tree May 21, 2020, 3:03 PM

#

@eternal inlet index is a much better experience yes

eternal inlet May 21, 2020, 3:03 PM

#

i usally plugin a speaker to my pc, ie. when i play pistolwhip or beatsaber

quiet vector May 21, 2020, 3:04 PM

#

oh

#

that's so weird! I guess it could make sense, I'm not used to that concept though since I mostly played Echo VR so you need the positional audio there

eternal inlet May 21, 2020, 3:05 PM

#

ah right... that makes sense

quiet vector May 21, 2020, 3:14 PM

#

I need to get this project farther along so I can justify buying an Index also, but man $1k is so much

tired tree May 21, 2020, 3:29 PM

#

@eternal inlet index speakers likely better than your desk speakers

quiet vector May 21, 2020, 4:09 PM

#

If primarily developing for oculus touch/quest do you guys recommend using steamVR plugin anyways? I'm thinking maybe I should so that later I can support knuckles controllers on vive or index (regular wands don't have enough buttons to really work I don't think). Or maybe I detect the hmd and swap the tracking method accordingly?

rich canopy May 21, 2020, 4:48 PM

#

@quiet vector it really depends where you want to release the game. If oculus then don't use steamvr. If steam then steam vr. If both then you need to have both working separately

quiet vector May 21, 2020, 5:02 PM

#

I see, thanks. For some reason I didn't quite understand that before but now it makes sense.

#

so for both would it be two builds? or one build that picks based on headset (assuming you didn't want to use oculus sdk on steam version)

#

hmm, then there is epic launcher itsellf

eternal inlet May 21, 2020, 5:36 PM

#

uh, just had a brainfreeze, how the heck is it i figure out which motioncontrollers are connected?

tired tree May 21, 2020, 5:52 PM

#

@eternal inlet not really a brain freeze, there isn't a built in way really

#

the new steam input you can sample the action source

#

which provides a model string

#

which you can compare too

eternal inlet May 21, 2020, 5:52 PM

#

oh, thought i had slept through the class hehe

tired tree May 21, 2020, 5:52 PM

#

I can give you an example node though that does it

eternal inlet May 21, 2020, 5:53 PM

#

that would be great

tired tree May 21, 2020, 5:53 PM

#

GetOpenVRControllerType in this source page from my module, there isn't a BP method really.

You can use the same string compares with valves plugin source check though.

Is there a way to disable Oculus and Steam VR from starting up every time a project is launched? There are times when I'd like to be able to preview in VR, however, both processes tend to make my 2080Ti overheat, and also changes my audio from speakers to the Rift S headset. Would love to figure out how to disable this, then turn in on when i need it. Thx.

How do I know/ test that my project has good performance for pc vr and possibly the pculus quest ?

I would really appreciate some guidance on this, please @ me

sturdy coral May 21, 2020, 7:36 PM

#

@real needle launch with -nohmd; but there are several bugs in it that make it not always work

#

one problem I found with steamvr is it forces off vsync I think even in editor or 2d, that requires a fix too to keep it from constantly maxing out your gpu

blissful bear May 21, 2020, 7:45 PM

#

Any idea what the steamvr vsync fix is?

sturdy coral May 21, 2020, 8:24 PM

#

for my game I just fixed it by issuing console cmomands, steamvr will only overwrite it at startup

#

the main thing was if you try and put the console commands into [SystemSettings] or [SystemSettings.Editor] it will end up still overriding them

#

the right way for them to fix it is to make a custom present class with SyncInterval = 0; // VSync off like the oculus plugin does

blissful bear May 21, 2020, 8:32 PM

#

Thanks. So issuing r.Vsync 1 should solve the noisy fan problem with my packaged builds. I'm gonna try now.

#

Worked a treat, many thanks!

@real needle launch with -nohmd; but there are several bugs in it that make it not always work
@sturdy coral Hey, i'm an Unreal noob, can you tell me how and where to execute the launch with -nohmd? I typically launch a project from My Projects in the Epic launcher. Can't seem to locate a command line for input. Thx!

sturdy coral May 21, 2020, 9:48 PM

#

@real needle go to Engine\Binaries\Win64 , right click ue4editor.exe and do create shortcut

#

then edit the shortcut and add C:\path\to\your.uproject -nohmd

real needle May 21, 2020, 10:02 PM

#

@sturdy coral Ok, shortcut created, now, where do i add this? In the Shortcut Properties? I can't find where to "edit" the shortcut.

sturdy coral May 21, 2020, 10:06 PM

#

@real needle yes

real needle May 21, 2020, 10:08 PM

#

@sturdy coral Where? In the Shortcut->Comment section? Also, this is only a stopgap for a particular project. I just want Oculus and Steam VR to not start at all unless I choose to. EDIT: Ok, i did a quick Google search, and see that i have to edit in the "Target" area.

#

@sturdy coral Sorry, still confused. How do you add the extra "C:\path\to\your.uproject -nohmd" to the already existing "C:\Program Files\Epic Games\UE_4.25\Engine\Binaries\Win64\UE4Editor.exe"? Originally, i just added the -nohmd to the end of this original line, but it still opened both Oculus and SteamVR when I double clicked the shortcut.

sturdy coral May 21, 2020, 10:40 PM

#

add it outside of any quotes if there are any

#

@real needle I think oculus has a bug where it won't work, it looks up your audio device and starts the oculus service even if you pass -nohmd

#

I'll try and put my patches up on github for it when I get a chance

#

steam is broken too because it queries which graphics adapter to use and starts up steamvr

real needle May 22, 2020, 6:24 PM

#

In the Unreal VR game starter using an Oculus HMD, there's a narrow focal length for the camera where objects in the distance are blurred. I'm not seeing this in the Post Process. Any idea how to reduce this?

If you started from a different template, you can try bringing the VR template's scalability inis over to your config folder

@sturdy coral Ah, I guess I'm just seeing the textures reduced with a tiny bit of AA. It's not bad on organic looking textures, but my initial grid had soft lines

Hi! Does any Go/Quest/GearVR dev know if you can use the native Oculus virtual keyboard in UE4 apps, in a similar way you can use the Android virtual keyboard in non-vr mobile apps? I can't seem to "summon" it when interacting with UMG text blocks.

@nimble adder Thanks!

nimble adder May 24, 2020, 3:38 PM

#

Np! You're stuck with reflection captures and cubemaps unfortunately

eternal inlet May 24, 2020, 6:24 PM

#

@sturdy coral i did some testing, and these are the numbers i came up with after switching around a bit

#

Index: 2400 x 2668 (142%)
Vive: 1852 x 2056 (142%)

#

raw resolutions with pixeldensity both set to 1.0

#

i grabbed those numbers from the GPU Visualizer, by looking at what the PostProcessing was reporting

#

📎 unknown.png

#

so im thinking that in order to get a sort of reliable way of benchmarking the miliseconds (which i've been doing on the Vive so far only), could be to downscale the Index to about the same raw resolution and then playtest to see if it hits about the same miliseconds... does that sound like a reasonable way to proceed?

#

according to my calculations, vive renders 3.807.712 pixels vs. index 6.403.200 pixels. Which corresponds to 168% pixels relative to the Vive.

#

so in other words, im guessing i should multiply pixeldensity with the reciproc of that 1.68 (0,5946576711644178) to get the same resolution

sturdy coral May 24, 2020, 8:31 PM

#

@eternal inlet yeah that sounds about right. You will probably still expect index to be a bit more expensive due to fov and less stereo overlap (less efficient instanced stereo), and hidden area mask

eternal inlet May 24, 2020, 9:04 PM

#

i'll run some tests with it over the next week and let you know if it seems reliable

eternal inlet May 24, 2020, 9:43 PM

#

@sturdy coral interresting, if i set Pixeldensity < 1.0, engine crashes (4.24.3), so in order to hit the same amount of pixels as Vive, you were right with the 77%, which i now set with r.ScreenPercentage instead

Hey im having an issue thats got me stumped wandering if anyone here might have a clue, ive added a tempry camera rotation to my game with 'add controller yaw input' and it works fine on an xbox controller, however it does not seem to work with the index control. both are mapped to the same input axis.. when i set it up to print the axis value to screen when you move the joystick the values show up fine for the xbox controler but it doesnt seem to print anything for the index? im confused as to why this would be ...i had the same issue with my movment stick but then it miraculously fixed it self ..leading to even more questions

#

i can get it to print axis values from the left index controller fine.. completly confused

junior grove May 25, 2020, 10:26 PM

#

Consumes the input?

#

I had the same issue with vive controllers that took me a while to figure out, since you have two controllers you need to always keep that in mind unless they are two different classes

Hi ! I use the stereo layer to make my interface vr. I want to give information to the player as if he could read it in a cosmaunaut's helmet. But I have several concerns:

I've tried different distance and size settings, but I still don't think it's great for the vision.
I tried to make some parts of my HUD transparent but they turn "black" instead of transparent.

Do you have an idea?

frigid kite May 26, 2020, 12:24 PM

#

@steady sparrow I believe that for the transparency issue, you have to assign a transparent material to your 3D widget

carmine yoke May 26, 2020, 12:26 PM

#

@steady sparrow Stereo layers are pretty bugged I've spoken about them quite a bit on here, what headset are you packaging for?

steady sparrow May 26, 2020, 1:08 PM

#

@frigid kite thx for advice i'm gonna check that.

#

@carmine yoke at first it will be for oculus rift but eventually it will be for steam vr.

#

But even when I launch the VR preview the problem of transparency is already there. So it is not a packaging issue atm

#

It's all about my incompetence i think lol

mighty carbon May 26, 2020, 1:15 PM

#

what is "PokeAHole" material? Is it a masked material ?

#

Asking cuz I saw this https://github.com/EpicGames/UnrealEngine/commit/5a533acfdb4432b2030378e5fe49e2a18bd45eb2 and I am wondering if that's related to alpha to coverage not working on Quest

frigid kite May 26, 2020, 1:33 PM

#

You should also be aware that stereo layers are different in Oculus vs SteamVR, @steady sparrow

steady sparrow May 26, 2020, 1:37 PM

#

He has a more "universal" way to make a HUD appear in vr? Stereo layer is the only way i had found (thx mitch on yt)

frigid kite May 26, 2020, 1:38 PM

#

You can use regular world widgets, but they're a lot less crisp than stereo layers

#

which is why stereo layers exist

#

However, on Steam you can't have anything rendering in front of them, at least you couldn't when I last used Unreal

tired tree May 26, 2020, 5:36 PM

#

@steady sparrow the plugin has a stereo layer widget component by the way

Does anyone know how to find out why the textures in this free prototyping asset pack show up as white on an Oculus Quest? https://www.unrealengine.com/marketplace/en-US/product/supergrid-starter-pack

SuperGrid Starter pack by ZeOrb in Environments - UE4 Marketplace

Super Grid is a pack of materials and modular meshes designed to make level prototyping faster and easier!

#

I'm only using it because it's listed as supporting Android, but the benefit of the materials scaling properly is entirely gone due to the assets showing up as solid white on the device

#

I switched from ES3.1 to Vulkan and repackaged, and it still shows as white, even though the Vulkan ES3.1 preview on desktop looks normal

thin solstice May 26, 2020, 6:14 PM

#

Look to see if Bloom is enabled for the project. Bloom is not recommended for quest, but you have to have bloom in order for emissive materials to work

#

I'm guessing the materials in the pack are emissive

bright drift May 26, 2020, 6:19 PM

#

Bloom was definitely disabled. I'll try packaging again. Thanks!

#

Still odd that it wasn't reflected in the mobile preview, though

#

@thin solstice bloom didn't help 😦

thin solstice May 26, 2020, 6:41 PM

#

Hmmm. Are the materials emissive?

bright drift May 26, 2020, 6:43 PM

There's a base color, roughness, and normal, but that's it

Hello! I'm having a horrible time just trying to get everything setup so I can simply Launch test levels to my Oculus Quest. I've followed the updated documentation, and jumped through a few of the hoops (missing repositories.cfg file, remove the lldb;3.1 steps) and now having problems just running adb when it is clearly installed in the specified path. This is with version 4.25. Also, i don't know if it makes a difference, but i'm running on an AMD Threadripper. Any help would be greatly appreciated! https://answers.unrealengine.com/questions/961570/view.html

#

between those 3 links, you should be good to go

real needle May 26, 2020, 11:36 PM

#

@bright drift Yes, i've read them all numerous time. I follow step-by-step, but there is always some little hiccup and then nothing works. For example, adb is clearly installed at the proper path, but when i try to use 'adb devices' it doesn't even recognize the command. How is the environment variable not set correctly upon installation? Also, i have no idea how to properly add the correct path. Any guidance there?

bright drift May 26, 2020, 11:37 PM

#

I just followed those links a week ago and set everything up just fine

#

adb wasn't in my path either, so I just navigated to where I installed it and used it from there because I was too lazy to add it

#

but to add to your windows path, hit the windows key, type env, hit enter, click Environment Variables, etc.

#

add a user var so you don't have to reboot or anything

#

er, edit your path var I guess

real needle May 26, 2020, 11:39 PM

#

@bright drift That's where i'm stuck - i get WHERE to edit the variable, i just don't know how to specify it properly.

bright drift May 26, 2020, 11:40 PM

#

click Environment Variables, click PATH under User variables, click Edit, click New, then paste in the directory your adb.exe is in

#

And if you don't know where it is, then search your C drive for adb.exe using Explorer and it should tell you

#

just right click it and click Open containing folder and then you can copy the path from there

real needle May 26, 2020, 11:41 PM

#

@bright drift Yeah, i'm there - do i create a new USER variable, or a SYSTEM variable?

bright drift May 26, 2020, 11:42 PM

#

I already said click PATH under User variables 🙂

real needle May 26, 2020, 11:43 PM

#

@bright drift Sorry, there is no "PATH" in that winder. Only the options "new", "edit", and "delete". I'm in the NEW window, and trying to add it there.

bright drift May 26, 2020, 11:44 PM

#

You don't have a PATH user env var already? I thought Windows had it by default. Did you scroll down?

real needle May 26, 2020, 11:44 PM

#

@bright drift d'oh - sorry, i see it. Was confused for a second there.

bright drift May 26, 2020, 11:45 PM

#

Np

real needle May 26, 2020, 11:47 PM

#

@bright drift Ok, that worked. Now when i type 'adb devices', it started up a daemon, then listed my Quest, but is says "unauthorized" even though it's been set to Developer Mode pretty much since i first got it a year ago.

bright drift May 26, 2020, 11:47 PM

#

I think you have to put the quest on and enable usb debugging each time

#

Maybe each time you turn it on, or each time you connect it, I don't recall

#

Man, I feel stupid about trying to run that damn demo earlier...

real needle May 26, 2020, 11:51 PM

#

@bright drift I'm using an ANKER USB 3.0 to USB C cable. I finally see that "Allow USB debugging" and clicked "always for this computer. I then enable the beta for Link. Now, adb devices shows "device" where before it was "unauthorized"

bright drift May 26, 2020, 11:51 PM

#

It's like 200k tris in every direction when Quest is supposed to be absolute max 50k

#

I'm not sure why you enabled the link beta if you're trying to do stuff in standalone @real needle

#

I dunno if it will let you copy stuff like a phone if it's in Link mode

I just checked and mine shows up as "device" too so I guess you're good to go

real needle May 26, 2020, 11:54 PM

#

@bright drift I thought you need to be in link mode to be able to PreviewVR and also to send over to the Quest from UE4?

bright drift May 26, 2020, 11:54 PM

#

I believe link is for pc vr only

#

you mentioned standalone earlier

#

if you're using Link, then you're previewing PC VR not standalone

real needle May 26, 2020, 11:55 PM

#

odd thing, now when i put the headset on (Quest) i get the three dots, then it stays black. It doesn't pop into Oculus Home like my Rift S does.

#

I recall it working in the past though. Weird.

bright drift May 26, 2020, 11:56 PM

#

it's still in beta

real needle May 26, 2020, 11:57 PM

#

hmm - so, is it different then is i were to use the originally supplied USB-C to USB-C cable to the PC? I recall being able to send some test projects over to the Quest from Unity back in February, and it just worked.

bright drift May 26, 2020, 11:58 PM

#

My understanding is that if you use the public test channel of the PC oculus software, you can use any USB cable for Link

#

But if you put your quest in Link mode, your PC will treat it as a connected VR headset

#

So if you're trying to preview VR apps meant for Quest standalone, you're going to get the wrong impression of what that's like, as you'll be previewing your game running on PC and not on the Quest

#

Basically, "Link" is a Quest app, so you can't run another Quest app while it's up, as far as I know

real needle May 27, 2020, 12:00 AM

#

Hmm. So, i can plug back in my Rift S, do my testing and PreviewVR with that, then when it's time to try and Launch a test, hook up the Quest and go from there?

bright drift May 27, 2020, 12:01 AM

#

I suppose

real needle May 27, 2020, 12:01 AM

#

also - is it advised to have both the Rift S and Quest plugged in at the same time?

bright drift May 27, 2020, 12:01 AM

#

all I do is dev and test on PC, then package for quest and deploy on its own when I wanna test

#

advised? I doubt it

#

I've had issues using VR with my vive while my quest was plugged in

real needle May 27, 2020, 12:01 AM

#

yeah, i'd kinda like to do that all with just the Quest

#

when you test on PC though, are you able to do the PreviewVR on the Quest?

bright drift May 27, 2020, 12:02 AM

#

I haven't tried it, but if you're in link mode, you can do a pc preview on quest, and otherwise, you should be able to do an android preview

#

but taking out the long cable is a pain so I just deploy and test standalone

real needle May 27, 2020, 12:03 AM

#

yeah, i know i've gotten it to work before. I'm also testing out a PC Laptop and was able to get it to work over there.

real needle May 27, 2020, 1:07 AM

#

Ok, here's an odd one: My Quest is attached (confirmed by 'adb devices') however, it's not showing up in UE4 4.25 Device Manager. So, I can't launch to it. I've tried manually adding it, but neither it's MAC address, or device number (from adb devices) seems to work. I know that the Quest should automagically appear in the list just right to the Launch tab, but no go. Any ideas?

#

Hey, I'm currently working on a multiplayer VR game and I have a small visual problem when connecting to a server.
When I join a server, the image inside my RV helmet freezes and if I move my head everything that was out of my field of view is black and artifacts appear.
I would like the screen to go black during loading. Do you have a method for that?

Hi all, I'm using the VRExpansion plugin and I have a lever that is rotating along the Y axis only. When I grab the lever, I can rotate it just fine but if I move my hand in real life, it "comes off" of the lever even though it still moves the lever, if that makes sense (i.e., the hand is still gripping it even though it's not virtually attached). How can I make my hand "stick" where it remains on the lever At the point of the original grip while the lever is being gripped?

@thin solstice see the grasping hands in the latest 4.24+ template

@tired tree I looked at the template and everything is working great in the Rift. However, when I compile for the Quest, for the "standard" hands, the collision sphere is shifted for both hands to the right of the hand, and when I change the hands to either of the grasping ones (with or without physics), the right hand is blue and is rotated 180 degrees where the thumb is pointing down, and both hand still have the collision sphere displaced. Have you run into this on the Quest?

tired tree May 29, 2020, 2:04 PM

#

@thin solstice you are on an older template?

#

a community member ported the left hand to a new model and I merged it in, but he used a steamVR only enum

#

it fails in quest builds

#

I had to revise it a week ago to use a generic controller identifier

thin solstice May 29, 2020, 2:22 PM

I'm pretty sure I'm on the newest template. I'll check to make sure. This didn't fail the quest build, only got skewed.

thats what i meant

it can't figure out the correct hand

because it was using an enum that doesn't work with quest

One thing I hate about VR dev is how the VR aspect is always so much more powerful when you fuck it up, added a haptic effect to the wrong hand when shooting a pistol and that really didn't feel good at all haha

I am very Keen to make a trailer for my project.
Primarily in mixed reality.
I have never caught mixed reality footage before and as I look into it, most of the capture methods require the game be capable of being caught that way..

Is it possible to capture fottage of my unreal project using mixed reality ?

I just don't think I will be able to convey what's going on to the VR un-initiated without this footage.
I would be greatful for any advice!

guys, im doing a Spectator screen using a SceneCaptureComponent2D, when i run my game, i start to get some strange spikes in CPU performance every 36 frame (or so). In a non spectator mode, my GPU is currently sitting around 4-6ms and the CPU at around 3-5ms. When i turn on the spectator stuff, it does that spike thing. I've tried to lower screenrenderresolution from 100 to 50, and then it goes stable to 4-5ms on the CPU. Any ideas what can cause this?

#

📎 unknown.png

#

actually here you can see my tick, is around 1.8 and what seem to take most of the time is actually Slate tick (for some other odd reason)

#

looking at the FViewExtensionPreDrawCommand, it seems there's a correlation with the spike there. though it's actually dropping

#

📎 unknown.png

#

looking at the frame just before the spike, i can see the FdrawSceneCommand pops up at a wooping 7.3ms

#

📎 unknown.png

#

where it's normally sitting at around 2-3ms

#

📎 unknown.png

#

hmm unfolding the FDrawSceneCommand, on the frame prior to the spike, i can see it eats up 4.9ms to "Delete Resources". Is that some kind of garbagecollection?

#

#

here's a snap of one of the "normal" frames, where "Delete Resources" only take up 0.1ms

#

scene capture fix? im on 4.25

sturdy coral May 30, 2020, 9:01 PM

hmm I think it is supposed to be fixed on that version

#

@eternal inlet try this anyway:

[/Script/Engine.RendererSettings]
r.SceneRenderTargetResizeMethod=2
r.SceneRenderTargetResizeMethodForceOverride=True```

#

must be set in ini and not console or it may not fully work

#

I think it was mainly for scene captures in shipping builds acting differently than in editor though

#

but I'm assuming your spectator screen is using a scene capture right?

eternal inlet May 30, 2020, 9:06 PM

#

yes correct, using a scene capture

#

the numbers i posted btw, was from editor... they're the same in built version though

#

will try your settings anyway

#

nope, sadly same issue

#

📎 unknown.png

#

with no spectator, the right graph (CPU) stay stable at around 4-5ms

sturdy coral May 30, 2020, 10:39 PM

#

@eternal inlet you might try profiling in visual studio to figure out what is causing it, otherwise add a stat to the destructor in everything that inherits from FRHIResource in RHIResources.h

#

also could try adding a second stat here before it gets to the deleters to see if it is the cause:


void FRHIResource::FlushPendingDeletes(bool bFlushDeferredDeletes)
{
    SCOPE_CYCLE_COUNTER(STAT_DeleteResources);

    check(IsInRenderingThread());                                                                                           FRHICommandListExecutor::GetImmediateCommandList().ImmediateFlush(EImmediateFlushType::FlushRHIThread);
    FRHICommandListExecutor::CheckNoOutstandingCmdLists();
    if (GDynamicRHI)
    {
//-----> add a second stat here to see if this is what is slowing down
        GDynamicRHI->RHIPerFrameRHIFlushComplete();                                                                         }

eternal inlet May 30, 2020, 10:42 PM

#

so you suggest i find the places in the engine and add those stats?

sturdy coral May 30, 2020, 10:43 PM

#

probably easiest is first to try the profiler

eternal inlet May 30, 2020, 10:43 PM

#

similar to the one you pasted: SCOPE_CYCLE_COUNTER(STAT_DeleteResources);

sturdy coral May 30, 2020, 10:43 PM

#

I fixed a similar issue in this area with the lightgrid where it was getting deleted and recreated every frame with dynamic res and changed it to instead overallocate based on max resolution

eternal inlet May 30, 2020, 10:43 PM

#

yeah i may stick to the profiler a bit longer, though i didn't find anything yet

sturdy coral May 30, 2020, 10:44 PM

#

I mean not hte ue4 profiler though

eternal inlet May 30, 2020, 10:44 PM

#

ah VS profiler

sturdy coral May 30, 2020, 10:44 PM

#

the visual studio one will cover all functions

#

the ue4 profiler is only the ones with stats

eternal inlet May 30, 2020, 10:44 PM

#

will look into ti

#

tbh, i've never used it

@tired tree When you mentioned that you revised the template to use a generic controller identifier, what identifier did you use and where was that set? Is this when you call the LoadControllerProfileByName function? I loaded the latest template but it is in 4.25 - my project is in 4.24 and I'm a little leery of updating to 4.25 right now as you have to load android studio, etc. for the Quest

tired tree May 31, 2020, 4:20 PM

#

@thin solstice there is a 4.24 branch of the template as well. But yeah, those controller profiles have a transform that can be applied to offset the controllers. They also used to be used for per controller button remapping before epic remade the input system in 4.24, to prep people for that eventual change.

@tired tree when you mentioned that you revised the blueprint a week ago to use a generic controller identifier, where was that? I am still getting the blue/inverted right hand when I compile for the quest, but everything is fine with the Rift.

@opal compass don’t ask to ask, just ask

opal compass Jun 1, 2020, 12:31 AM

#

alright

#

i'm trying to make a third person game similar to that of moss that uses both motion controllers and a third person character

#

how would i go about doing that

sturdy coral Jun 1, 2020, 12:32 AM

#

@opal compass in the learn tab look at the couch knights project

#

It is a bit out of date now as it was one of the earliest

opal compass Jun 1, 2020, 12:34 AM

#

alright, i'll try

tired tree Jun 1, 2020, 12:41 AM

#

@thin solstice in the grasping hand blueprint, the laterality variable was changed to be of the type EControllerHand

#

i did just specifically test yesterday with quest to make sure it was working

opal compass Jun 1, 2020, 12:46 AM

#

@sturdy coral it says it isn't for sale :/

sturdy coral Jun 1, 2020, 1:03 AM

@opal compass it should be free, are you in the learn tab?

I’ve never seen anything for sale in there

Greetings @everyone , I'm struggling with the implementation of IAP for Oculus Go/Quest. I've read through their documentation on Oculus developer site and also tried the "VRMonkey" plugin, which was released years ago and doesn't work on the current version of UE4 (at least I can't get it worked).
Could someone be so kind and share some steps how you get the IAP done? (C++ or BP, doesn't matter, as long as I can get it done. I have been googling so much and still no luck ☹️ )

shadow radish Jun 1, 2020, 2:48 PM

#

hi all you wonderful VR people

#

Sponge I am not familiar with IAP integration sorry

#

I've been working on an update for my game the last five months, I had a somewhat disappointing launch

#

converting it to be more open world, got a lot of feedback people were against wave based games

#

anyone have any inspiring stories of a struggled launch but rebound for their VR game I can draw some hope from?

thin solstice Jun 1, 2020, 3:09 PM

#

Not personally but No Man’s Sky is probably the poster child for a horrid launch with a rebound. Sorry to hear about your disappointing launch.

mighty carbon Jun 1, 2020, 3:13 PM

note that Sony and a lot of money were behind No Man's Sky.

@tired tree i am having a problem when trying to setup the finger tracking in the example template. The hand becomes offset

📎 unknown.png

#

is there a way that I can fix this?

tired tree Jun 2, 2020, 12:16 AM

#

@hot willow turn off bone morphing, morphing doesnt work correctly with manniquin hand anyway since it's not skinned for it. That is the root bone offset to align it to the controller if you want it to.

hot willow Jun 2, 2020, 12:46 AM

@real needle @sturdy timber @thick linden @ebon scaffold @undone ruin @quiet badger @narrow topaz
fix for -nohmd (oculus audio causing oculus launch and graphics adapter query making steamvr launch):
https://github.com/EpicGames/UnrealEngine/pull/6980

just @mentioning everyone I found in search that trying to fix this in the past

#

for people with broken hand animations in -game mode:
https://github.com/EpicGames/UnrealEngine/pull/6981

you also have to change the module type in the steamvr input uplugin somewhere, I didn't include that yet because I use mordentral's openinputplugin that supports hand animation with full body and replication

#

the change for his is:

[OpenInputPlugin.uplugin]

        {
            "Name": "OpenInputPluginEditor",
-            "Type": "Editor",
+            "Type": "EditorOrEditorGame",
            "LoadingPhase": "PreDefault",
            "WhitelistPlatforms" :
            [
                "Win64",
                "Win32",
                "Linux",
                "Mac"
            ]
        }```

#

@tired tree looking at physxvehicles just now I think that fixed it with UncookedOnly ; change would be:

[OpenInputPlugin.uplugin]

        {
            "Name": "OpenInputPluginEditor",
-            "Type": "Editor",
+            "Type": "UncookedOnly",
            "LoadingPhase": "PreDefault",
            "WhitelistPlatforms" :
            [
                "Win64",
                "Win32",
                "Linux",
                "Mac"

Hi all.
Can anyone give me some advice on making VR loading screens ?
I would really like to put the player into a blank room with a widget containing information about the level they are loading.
I watched the live training unreal put out for a loading screen but that was for non VR, I was wondering how different it is ?

abstract venture Jun 2, 2020, 7:55 AM

#

Heya there. I've started out a VR project (from the VR template, quite modiified now), kinda struggling with how camera works. I'd like to follow a projectile for instance but i always find myself above the projectile and the position of the camera in the viewport doesn't seem to matter. Same when controlling a third person character, can't seem to affect the camera much. Any ideas ?

sturdy coral Jun 2, 2020, 8:36 AM

#

@abstract venture in default setup every tick the camera’s relative position is updated to he hmd position

#

So any change to camera position elsewhere will get erased

#

Instead you should attach camera to an empty scene component, and move that to move the camera, including for default offset to your projectile

abstract venture Jun 2, 2020, 8:40 AM

#

ok, thx, i'll try that out 🙂

#

I'd also like to get a progress bar on top of say, the VR hands but can't seem to make it appear. Managed with a third person but not in VR, is there a different way to make it work ?
Actually, are there general difference that I should know about between VR and non VR dev on unreal ? If there's a good resource (video, documentation, article) i'd be keen. Cause there are a lot of good stuff on youtube but I found that numerous don't seem to work with VR

does anyone have advice on how to pull the drag-to-move function from vr-mode into your own project? I am new to unreal and have been using blueprints, but it looks like all of the vr-mode attributes are in cpp (which I'm not super familiar with yet) somewhere around here: https://github.com/EpicGames/UnrealEngine/blob/f8f4b403eb682ffc055613c7caf9d2ba5df7f319/Engine/Source/Editor/VREditor/VREditorAvatarActor.cpp#L371

What's a good way to do water with VR? I really like the look of this shader: https://www.unrealengine.com/marketplace/en-US/product/cartoon-water-shader However I highly doubt it will work with VR. Am I mistaken?

Cartoon Water Shader by Adam Homoki in Materials - UE4 Marketplace

Cartoon Water Shader is an easy to use highly stylized water material, and river tool with many features.

mighty carbon Jun 2, 2020, 2:35 PM

#

it just might - he offers mobile shader in his package

#

what's going to kill performance is translucency - can't have depth fade without it

#

and distance fields eat up RAM like crazy on Quest, so I didn't try the other method

#

on PC it should just work

radiant garden Jun 2, 2020, 2:51 PM

#

Really? That would be awesome if it did. I just recently switched over from Unity and was having lots of problems with water shaders and stereoscopic rendering (the shader would work in one eye but not the other). I've only been using UE for about a day, so I have much to learn.

#

So far the rendering capabilities have blown Unity out of the water. I brought over a few assets from Unity and was absolutely stunned on how much better they look with default rendering in UE.

cosmic shoal Jun 2, 2020, 3:01 PM

#

Yeah, you can make Unity look really pretty, but you need to donwload stuff and enable stuff and do all kinds of stuff 🙂

radiant garden Jun 2, 2020, 3:01 PM

#

Unity is a spectacular prototyping tool

#

Been working in it for around 8 years, and every.single.project hits huge problems around 70-80% complete because it's not a fully implemented engine

cosmic shoal Jun 2, 2020, 3:02 PM

#

maybe you are over ambitious hehe we have several things done in Unity

radiant garden Jun 2, 2020, 3:02 PM

#

Perhaps

#

Most my stuff has been mobile, but that includes bluetooth controllers for robots

#

I wasn't saying the projects were not complete, I was saying there were always snags where we had to (re)write something we didn't think we would need to

cosmic shoal Jun 2, 2020, 3:04 PM

#

We have a few mobile apps, VR apps and a lot of webGL stuff.

frigid kite Jun 2, 2020, 3:04 PM

#

Unreal has its own set of problems though

radiant garden Jun 2, 2020, 3:04 PM

#

Which problems are good to keep an eye out for?

mighty carbon Jun 2, 2020, 3:05 PM

#

4.25.1 is still not out!

frigid kite Jun 2, 2020, 3:05 PM

#

In general, it seems that they have not looked at VR since the release of robo recall

@mighty carbon do you also have experience with Unity VR dev, or just unreal?

mighty carbon Jun 2, 2020, 3:07 PM

#

there are quite a few basic issues that should have been fixed in 4.16 or even earlier.. Yet, those issues still present and simply being shoveled over to the next releases

#

and with UE5 on the horizon, I have little faith in Epic in regards to VR

#

@frigid kite just Unreal

#

(and mostly on art/design side with a sprinkle of BP)

frigid kite Jun 2, 2020, 3:08 PM

#

and with UE5 on the horizon, I have little faith in Epic in regards to VR
I'm cautiously positive about Nanite also being beneficial to VR, though it's likely deferred only

mighty carbon Jun 2, 2020, 3:09 PM

#

it's likely not going to work in VR at all

frigid kite Jun 2, 2020, 3:09 PM

I believe they said that it will work for high end VR

mighty carbon Jun 2, 2020, 3:10 PM

#

all smoke and mirrors I bet

#

I believe it when I see it

radiant garden Jun 2, 2020, 3:11 PM

#

Is it reasonable to do high end and mobile VR in the same project?

cosmic shoal Jun 2, 2020, 3:11 PM

#

I think it's gonna be like VR. It works, it's quirky and it's not for everyone.

radiant garden Jun 2, 2020, 3:11 PM

#

Or should they essentially be considered different games?

frigid kite Jun 2, 2020, 3:11 PM

#

You're saying that based on their VR track record, or based on how you think the technology works?

#

@radiant garden Unreal has some really good scalability tools, much better than Unity

#

(Because of Fortnite)

#

You can easily swap out assets based on quality level right in the model/texture properties, for instance

radiant garden Jun 2, 2020, 3:12 PM

#

So you can have one set of materials for high end and a different for mobile?

frigid kite Jun 2, 2020, 3:13 PM

#

Yeah, and auto generate lods and have different lod sets for mobile for instance

radiant garden Jun 2, 2020, 3:13 PM

#

Or does it go even deeper than that, allowing for different mesh complexities for the quality levels?

cosmic shoal Jun 2, 2020, 3:14 PM

#

If the quest wasn't so popular I'd tell you to do high end first then optimize for mobile

radiant garden Jun 2, 2020, 3:15 PM

#

Yeah I'm starting to view the Quest as an annoyance :/

#

I have an Index myself

#

and a mid to high end pc

#

So I'm really concerned on how I'm going to manage profiling to make sure I support mid to low end devices

frigid kite Jun 2, 2020, 3:16 PM

#

The only true way is getting a low end device

cosmic shoal Jun 2, 2020, 3:16 PM

#

There is a talk by SuperHot developers, descriving how they optimized super hot for quest. Really good info there.

frigid kite Jun 2, 2020, 3:16 PM

they did murder robo Recall tho 🙂

frigid kite Jun 2, 2020, 3:16 PM

#

I dunno, I think it's still fine

#

I played it on the Quest only very briefly, but I was quite surprised how well it still played and looked - it looked terrible in the screenshots

radiant garden Jun 2, 2020, 3:17 PM

#

Doesn't most VR look bad in screenshots?

cosmic shoal Jun 2, 2020, 3:17 PM

#

as far as quest games go it looks pretty good I guess

frigid kite Jun 2, 2020, 3:17 PM

#

I wouldn't say that @radiant garden

cosmic shoal Jun 2, 2020, 3:18 PM

#

Not really

#

Alix screenshots look great

mighty carbon Jun 2, 2020, 3:18 PM

Quest is the future.. That's where the money is at

#

Next HMD will have better SoC and will be wireless most likely

#

radiant garden Jun 2, 2020, 3:19 PM

#

Does Quest have a large install base?

frigid kite Jun 2, 2020, 3:19 PM

#

after psvr probably the biggest by now? I'd have to check

radiant garden Jun 2, 2020, 3:19 PM

#

Sorry if I'm a bit naïve on VR topics. I've only been working with it for about a month.

frigid kite Jun 2, 2020, 3:20 PM

#

I definitely believe that if you want to ship a VR game, it would be foolish to leave out the Quest

#

You just have to be approved by Oculus/Facebook first

radiant garden Jun 2, 2020, 3:20 PM

#

Doesn't that just mean passing their test?

frigid kite Jun 2, 2020, 3:20 PM

#

They're apparently notoriously picky

radiant garden Jun 2, 2020, 3:20 PM

#

Oh funny

#

Are they picky about dev skill sets, or about game quality?

frigid kite Jun 2, 2020, 3:21 PM

#

On what they decide fits in the Quest ecosystem

#

It's a bit arbitrary

#

Basically it means that it's mostly established VR publishers that get on there

mighty carbon Jun 2, 2020, 3:22 PM

#

kinda like getting your game to PS4, but with tighter requirements

frigid kite Jun 2, 2020, 3:22 PM

#

For instance, they only just allowed productivity apps like spatial.io on there a few weeks ago - there's no reason why it was not allowed from the start

radiant garden Jun 2, 2020, 3:23 PM

#

That is odd

frigid kite Jun 2, 2020, 3:24 PM

#

Still, it's a very popular platform that you can't afford to ignore

radiant garden Jun 2, 2020, 3:25 PM

I built a few "punch gesture recognition"... thingies in C# on Unity. I'd like to port these to C++ in UE4. Is there a good API list for getting tracking and input data for VR?

#

I've been dabbling with the VRExtension plugin. Seems really solid so far.

#

I plan on exposing the gestures as blueprints to do the rest of the game logic

#

I wasn't sure if it is best to try to get input data from UE directly, or if there was an API I would be wise to use from the plugin

tired tree Jun 2, 2020, 3:37 PM

#

@radiant garden you can directly sample tracker information yes, but at that point just sampling the relative location of the motion controller components will work

radiant garden Jun 2, 2020, 3:38 PM

#

@tired tree Oh hey! I've been super impressed with your plugin so far!

tired tree Jun 2, 2020, 3:38 PM

#

your c# should also mostly 1:1 convert

radiant garden Jun 2, 2020, 3:39 PM

#

I feel I've been around the racetrack trying VR on every platform so far (in terms of prototyping stuff), and your plugin has been far superior to a lot of what I've seen.

#

I was hoping so

#

I'm mostly doing distance comparisons and dot products to determine if a particular movement should register

tired tree Jun 2, 2020, 3:41 PM

#

I do also have a gesture component using dynamic time warp @radiant garden

#

though if you are looking for very general motions a naive sampling like yours would likely outperform and be more reliable

radiant garden Jun 2, 2020, 3:42 PM

#

I'm looking for certain types of punches

#

So a "symbolic" gesture recognizer would likely struggle with the finer details

tired tree Jun 2, 2020, 3:43 PM

#

you may want to play with the gesture component then

radiant garden Jun 2, 2020, 3:43 PM

#

All the motions are essentially straight lines

tired tree Jun 2, 2020, 3:43 PM

#

it has thresholds

radiant garden Jun 2, 2020, 3:43 PM

#

Oh interesting

#

I will check it out

tired tree Jun 2, 2020, 3:43 PM

#

and speed shouldn't effect it as long as the sample buffer is long enough to cover it

radiant garden Jun 2, 2020, 3:43 PM

#

I've been going off distance magnitudes, velocities, and angles of travel

#

Faster actually makes it more difficult because you end up with fewer datapoints

#

and the points can be a bit more noisy

#

@tired tree Is the gesture system the one on the table in your example level?

tired tree Jun 2, 2020, 3:45 PM

#

yeah, its just a component on that wand, could attach to controllers instead

#

and run always on sampling

radiant garden Jun 2, 2020, 3:45 PM

#

What is the feedback when you successfully perform the gesture?

tired tree Jun 2, 2020, 3:46 PM

#

event is thrown with a copy of the gesture

radiant garden Jun 2, 2020, 3:46 PM

#

I played with it for a few minutes yesterday, but I wasn't quite certain how to use it

tired tree Jun 2, 2020, 3:46 PM

#

i have a few people using it with hand pose gestures to do spell casting and the like

#

you can pm me if you have questions about implementation for it, I dont have a tutorial for it besides the wand reference implementation currently

radiant garden Jun 2, 2020, 3:48 PM

#

Did you base it on the $1 recognizer algorithm sometimes used in 2D recognition?

frigid kite Jun 2, 2020, 3:50 PM

#

I feel I've been around the racetrack trying VR on every platform so far (in terms of prototyping stuff)
Have you also tested VRTK?

tired tree Jun 2, 2020, 3:52 PM

#

@radiant garden no, its a low featured Dynamic Time Warping function

radiant garden Jun 2, 2020, 3:59 PM

#

@frigid kite I looked at it briefly. For my purposes I felt SteamVR gave a better start and if I stuck with Unity I was going to port the functionality I needed for Oculus.

frigid kite Jun 2, 2020, 4:00 PM

#

Yeah I also decided to run with SteamVR, I found VRTK to be horribly over engineered

radiant garden Jun 2, 2020, 4:00 PM

#

That was pretty much my impression as well

frigid kite Jun 2, 2020, 4:02 PM

#

I also really dig VRE, but my project is heavily dependent on compute shaders and from what I see those are not really well exposed in UE

tired tree Jun 2, 2020, 4:03 PM

#

@frigid kite well you do have full engine source available to you

#

but i guess that is a bit heavy handed if you aren't accustomed to it

frigid kite Jun 2, 2020, 4:03 PM

#

Indeed, heavy handed compared to "it just works"

radiant garden Jun 2, 2020, 4:03 PM

#

When Unity "just works" it is wonderful

#

When it doesn't, you end up losing a limb

#

🙂

frigid kite Jun 2, 2020, 4:04 PM

#

I have been contemplating making the switch, but in general I find development in UE to be a bit slower; compile times, build times

cosmic shoal Jun 2, 2020, 4:04 PM

#

If by limb you mean your hair.

radiant garden Jun 2, 2020, 4:05 PM

#

Nah actually I mean you lose a lot of sleep from crunch b/c you suddenly have new features to develop

frigid kite Jun 2, 2020, 4:13 PM

#

That also happens with UE, @radiant garden

It's a lot more feature complete than Unity, but that doesn't mean you won't run into situations where you run into a dead end

radiant garden Jun 2, 2020, 4:13 PM

#

At least you have the source code

#

The situations I've run into, were where Unity's implementation is inadequate and ends up requiring a lot of rework - or otherwise makes it more difficult to do a work around

Though my usages have been a bit "off the beaten path"

read what they do and make it in BP

#

its prolly something like get locationg when u press , than get the vector of the movement ,. invert that

#

or u could check out the virtual production pawn, it might have that exact same thing in BP

#

not sure if ur allowed to use engine content for games , but this prolly wont be a problem

#

i think thats more for stuff like using the landscaping tool as level editor

Anyone use the quest? first time setting it up, followed a tutorial, I can't seem to play it in Play, simulation. UE4 recognizes my headset but still cant test

Any tips

granite idol Jun 3, 2020, 10:58 PM

#

Anyone?!

abstract venture Jun 3, 2020, 11:16 PM

#

got a link ?

#

you need oculus link with quest to go play

#

otherwise you need to compile your apk and upload it to the quest with adb (or sidequest)

#

i might be slighty wrong with the adb and sidequest thing as I never did it but that's what I understood

#

I've seen that with the latest oculus link you can do it with the shipped 3m cable now, but you still need to have oculus link ready before you start your project for it to work inside UE4

granite idol Jun 3, 2020, 11:26 PM

#

@abstract venture I just got a cable today, I hooked it up and I didn't make a build yet ahha

#

BUT I did download steam VR and it worked...kind of. It was hella choppy which was a bummer. I need a new pc probably

#

I do have side quest so I will have to try it out once the build is done

@hallow knoll is there any way you could ask around? 😊

cuz not having MSAA (and alpha to coverage MSAA is what's needed for masked materials) would be an automatic reject from having game on Quest

@keen prawn you can use engine and plugin content, mostly just not stuff under 'Editor' folders

or 'PluginNameEditor' (probably includes fracture editor)

Asked this in #graphics and got pretty much crickets. My coworker is using Unity to work with the same fbx I am, and he found some settings that helped him get the frame rate way down. I'm still struggling with it. What he did was changed the mobile shader from Bumped Diffuse to Diffuse (since we realized some things we thought were bump maps weren't).

📎 unknown.png

#

Is there anything equivalent in UE at all for mobile shaders?

mighty carbon Jun 4, 2020, 6:01 PM

#

unlit maybe ?

#

other than that, UE4 shaders are not really made for mobile VR.. Ideally you need to rewrite lighting and shaders in UE4 to maximize performance on Quest

#

if only Epic cared more about mobile VR or Oculus cared more about using UE4 for Quest, we'd probably have a lighting model and shaders optimized for Quest

@mighty carbon no, he's definitely using baked lighting

so the answer is "yeah, I just may have sucky performance on the exact same scene because I use UE"? That is, without adding in optimizations that he's not.

#

Does anyone have any documentation on running an android preview with the debugger attached on Quest?

#

I'm trying to debug a crash with one of the plugins I'm using

#

Is using Android Studio the only option? https://docs.unrealengine.com/en-US/Platforms/Mobile/Android/AndroidDebugging/index.html

Android Debugging

Taking a look at how to debug your UE4 project using Android Studio.

#

That page doesn't work for 4.25

#

I skipped the step about adding the line with the python script, since that folder isn't on my pc in 4.25, and when I try to debug, the device says it's waiting for the debugger to attach

#

Android Studio never asks for a device even though it does launch the app on the quest

#

Nvm, I think I got it

bright drift Jun 5, 2020, 12:59 AM

#

Does anyone have tips for packaging for quest faster?

#

I think I found the right page for this: https://developer.oculus.com/documentation/unreal/unreal-ide-guide-android/

last knot Jun 5, 2020, 2:05 AM

#

@mighty carbon So, given what you told me earlier, would you say developing a VR app for Quest in Unreal maybe isn't a great idea? Stick to unity?

mighty carbon Jun 5, 2020, 2:07 AM

#

well, if you have no hope finding someone to implement certain things, either make sure your project doesn't use unsupported features or look into Unity, yeah

#

I am sure Unity has its fair share of shit to deal with

#

but at least there are a lot more devs available there if you need help and a lot more stuff in the Assets store

#

and it's Oculus main in-house engine, so probably a lot better supported on Quest

#

I don't have much issues with performance on Quest with UE4

#

it's just missing / broken things

bright drift Jun 5, 2020, 2:48 AM

#

what's missing/broken?

last knot Jun 5, 2020, 2:48 AM

#

Thanks for the perspective. We're kind of just getting into VR dev (with Quest as our main platform target), and the boss has me doing UE and my friend/coworker doing Unity. He want to "keep all the options open", but it feels like a lot of wasted effort. I think that I'm going to have to really plead with him to abandon UE and let me switch to Unity. Which... god, that's real cruelty. I would MUCH rather be working with UE.

bright drift Jun 5, 2020, 2:49 AM

#

I'm also using UE4 for a multiplat game mostly targeting quest (assuming I even get approved by Oculus)

last knot Jun 5, 2020, 2:50 AM

#

@bright drift well, I can just quote one thing that @mighty carbon just recently posted:

VictorLerp what are the chances for alpha to coverage MSAA for ES3.1 / mobile Vulkan to be implemented in 4.26 ?
cuz not having MSAA (and alpha to coverage MSAA is what's needed for masked materials) would be an automatic reject from having game on Quest

bright drift Jun 5, 2020, 2:52 AM

#

I'm not sure I'm keeping up with most of that sentence

#

but I take it UE4 on Quest doesn't support the specific type of MSAA that's performant enough to be worthwhile?

#

at least, for the use case of "masked materials?"

mighty carbon Jun 5, 2020, 3:18 AM

#

@bright drift UE4 doesn't support alpha to coverage MSAA on Android (ES3.1 / Vulkan) at all. It's not in the engine at all. Nothing.

#

@bright drift https://medium.com/@bgolus/anti-aliased-alpha-test-the-esoteric-alpha-to-coverage-8b177335ae4f

#

that's what it is on Unity

#

you only need a2c on masked materials, because other materials with alpha transparency don't need it

#

(and you don't want to use blended transparency on Quest, only additive and masked, for performance reasons)

#

and this is what's broken https://issues.unrealengine.com/issue/search?q=fix%3A4.26&resolution=unresolved&component=xr&sort=

#

most of those issues keeps being pushed over since before Quest was a thing

bright drift Jun 5, 2020, 3:23 AM

#

I guess I'm thrown off on why this is a dealbreaker because I'm pretty sure there are multiple shipped UE4 quest games

mighty carbon Jun 5, 2020, 3:24 AM

#

not really

#

the ones that are shipped either made by ex-AAA devs who added what's missing themselves, or internal Oculus projects that also added whatever was missing themselves

#

and no, there are not whole a lot of UE4 based games on Quest

bright drift Jun 5, 2020, 3:25 AM

#

that sounds pretty ominous

mighty carbon Jun 5, 2020, 3:26 AM

#

and since we complain about it, we are obviously no capable implementing a2c MSAA 😅 😊

#

(at least I am not)

bright drift Jun 5, 2020, 3:31 AM

#

On Quest, when I try to use the DebugWidget (by calling PrintString_DW in a blueprint), it just crashes. I'm trying to debug it so I can help the dev who made that plugin fix it, but I'm having trouble getting anything useful from the crash

#

I tried a logcat and didn't get anything useful beyond some technical way of saying "it crashed", "SIGSEGV"

#

I tried running it with Android Studio's debugger attached and it said that it tried to access an invalid memory location

mighty carbon Jun 5, 2020, 3:32 AM

#

are you in Oculus Start ?

bright drift Jun 5, 2020, 3:32 AM

bright drift Jun 5, 2020, 3:34 AM

#

Tbh, back in october I ran into an awful engine regression on quest

#

got no help from users or Epic, ran to godot for several months. very bad idea

mighty carbon Jun 5, 2020, 3:34 AM

#

also, for Quest you are better off using Oculus fork of UE4

bright drift Jun 5, 2020, 3:34 AM

#

really? why? for the newer SDK?

mighty carbon Jun 5, 2020, 3:35 AM

#

yeah.. SDK is up to date (at least the main one), easier to get dev support help, they also sometimes have tweaks to the engine to make sure it runs well on Quest

bright drift Jun 5, 2020, 3:36 AM

#

hmmm

mighty carbon Jun 5, 2020, 3:36 AM

#

also, Quest requires for SDK to be no less than certain version

#

and since stock UE4 drags behind, you might end up in a situation that your build will be rejected due to older SDK being used

bright drift Jun 5, 2020, 3:37 AM

#

well, I'm not concerning myself too much on oculus restrictions til I get an OK from them. I'm just trying to keep the game performant in the meanwhile with occasional device tests

mighty carbon Jun 5, 2020, 3:37 AM

#

(or it might even not run at all)

bright drift Jun 5, 2020, 3:37 AM

#

any idea why this would happen? LogCook: Display: Cooked packages 693 Packages Remain 1 Total 694

#

I'm trying to launch from the editor to figure out that crash, but either it gets stuck on the last cooked package or I enable cooking on the fly and it just fails and doesn't say why

#

maybe I should just try this all again from the oculus fork...

#

all of the problems I've had since coming back to UE4 have been specific to quest

#

I'm using the SuperGrid free asset pack for prototyping, but the materials are very funky on quest even though it's set up to support android

mighty carbon Jun 5, 2020, 3:39 AM

#

nah, no idea. I found out that running from Editor on Quest is not a great idea because sometimes it runs fine like that, but shipping cooked build crashes.. So might as well just build shipping apk for tests.

#

(or sometimes it won't run, like in your case)

bright drift Jun 5, 2020, 3:40 AM

#

hmmmm

#

so yeah, right now I have the problem of the debug widget crashing (and thus being unusable) and this texture thing: https://www.youtube.com/watch?v=iwqtjjEP4K4

mighty carbon Jun 5, 2020, 3:41 AM

#

hmm. I never used SuperGrid, so I wouldn't know 😦

bright drift Jun 5, 2020, 3:42 AM

#

I asked the pack's author and he said it had something to do with how his parent material's set up and how epic's changed stuff about that across engine versions

#

I dunno enough about it to fix it myself yet, and this debug widget crash... I still haven't figured out how to get useful debug info from the crash

#

I figured if I launched from the editor I might get a crashreporter pop up with something actionable, but I can't even get that far

#

and it sounds like using the oculus fork wouldn't help that too much

mighty carbon Jun 5, 2020, 3:52 AM

#

why do you use debug widget ? (I don't even know what that is)

#

I just use Print String, stat cmds and logcat.. Sometimes I use RenderDoc.

bright drift Jun 5, 2020, 3:55 AM

#

debug widget is a pretty simple plugin

#

basically a widget with a text display set up on it

#

I can call "PrintString_DW" from any blueprint, and I have the widget attached to the HMD camera so I can easily see whatever

#

on PC, the regular debug log text is tiny and in a far corner of the display in the headset, so it's nearly impossible to read

#

given that linking github to an epic account is apparently completely broken across multiple browsers right now, maybe I should just stop going down this rabbit hole

tired tree Jun 5, 2020, 3:58 AM

#

Did you not see the debug console in that level? @bright drift

#

With the keyboard

bright drift Jun 5, 2020, 3:58 AM

#

what level? the template?

tired tree Jun 5, 2020, 3:58 AM

#

Yes

bright drift Jun 5, 2020, 3:58 AM

#

that's not what I mean

#

but I guess I could just copy that

tired tree Jun 5, 2020, 3:59 AM

#

It prints out the entire log

#

Output log

#

So normal print commands show on it

bright drift Jun 5, 2020, 3:59 AM

#

the debug widget is nice because it took almost zero effort or time to get it working

#

Tbh, the main reason I was spending time figuring out why it was broken on quest was because that seems like something I should be able to do in general

#

As of right now, at least until I port your console over, I don't have any way of reading debug text or actually debugging at all on the device

#

I can package and install, but if it crashes I'm kinda at a loss

#

On PC I get a crash reporter or I can attach visual studio and just look at it

carmine yoke Jun 5, 2020, 8:13 AM

Hey guys, I just migrated my Quest project to 4.25. Initially it would crash on load saying "Object StereoLayerShapeQuad StereoLayerShapeQuad_0 created in Package instead of StereoLayerComponent". So I rolled it back and deleted Stereo Layers from all of the relevant BP. Now it opens fine in 4.25, but when I try to package it says the same problem. I've literally removed every instance of a stereo layer, so why is it still happening?

@mighty carbon I need to setup a small VR project in Unreal, something that I haven't done before. I was told that VRTK is a good option for people who only have Keybaord and mouse, but its only for Unity. Because I want to learn Unreal, I'm looking for an alternative way to get started

mighty carbon Jun 5, 2020, 1:51 PM

the whole premise of VR is to be able to dive into another dimension, so to speak, physically.. Meaning using motion controllers and physical interactions.

blissful bear Jun 5, 2020, 2:00 PM

@real needle Look into using the VRExpansion plugin for Unreal. It gives you a great example map to study from and should allow you to use a first-person player with mouse and keyboard and then full vr once you get the hw.

mighty carbon Jun 5, 2020, 2:01 PM

if you wan to learn UE4, just learn it making a small pancake game. Sell it, make some money, buy yourself proper VR hardware.

or

make a decent concept, apply for Oculus Start and they'll send you Rift S and Go for free

I mean it sounded like the resulting position and rotation was in local space to the pawn, but I was a bit confused on how to get the pawn's position and rotation

Hey guys , what is the best way to match scale of Real world Objects inside VR ?

frigid kite Jun 5, 2020, 4:00 PM

Measure and make to scale?

mighty carbon Jun 5, 2020, 4:16 PM

even with that VR world appears out of scale due to restrictive FOV, imo.. It never looks right

carmine yoke Jun 5, 2020, 5:34 PM

#

@hallow knoll Don't worry, I saved/relit a couple of levels which must have had some kind of residual reference to a stereo layer. Managed to get it to package!

Hi there

Anyone having troubles with motion controller tracking on oculus quest?

ue 4.24

Mine controllers stay on the floor

maiden willow Jun 6, 2020, 12:46 AM

#

@sinful vault are you using the VR template in the motion controller map to test?

languid night Jun 6, 2020, 1:11 AM

#

Anyone here have any experience working with oculus native sdk?

mighty carbon Jun 6, 2020, 1:17 AM

#

highly unlikely @languid night

#

since UE4 comes with integrated SDK, no point in using native SDK with UE4

languid night Jun 6, 2020, 1:17 AM

#

That is true, I was just curious

sinful vault Jun 6, 2020, 1:36 AM

#

@maiden willow the template pawn and motion controllers work. But any other pawn or motion controller, even the simplest one doesnt works now.

maiden willow Jun 6, 2020, 1:49 AM

#

There are a few bits that are necessary to attach your controllers to the HMD. I rewrote a lot of it just to understand the flow and what was being accomplished

Can anyone advise me on/ point me towards some info on VR loading screens and how to make them ?

Most VR loading screens I have seen in games are within a black/empty room with maybe a dialog box/illustrations.
THAT is exactly what I am hoping to create for my project..

smoky valve Jun 6, 2020, 10:54 AM

#

Hi all, I'm using 4.25. The project builds without errors in the output log, but I'm getting this error in the headset. I'm hoping some of you can shine some light on this issue I'm having. You're help is much appreciated.

q: is Instanced Stereo recommended on desktop? I vaguely remember reading that it turned out not to be a performance win but that might have been on mobile

sturdy coral Jun 7, 2020, 1:43 AM

#

@silver robin it is supposed to relieve cpu but increase geometry work, so it likely depends on if you are draw call bound or not

#

but I don't know how much that changed after 4.22 added automatic instancing everywhere, that may already have a geometry overhead that doesn't get compounded somehow

silver robin Jun 7, 2020, 1:49 AM

hmm okay, thanks

doesn’t seem to make a whole lot of difference to my project so I guess I’ll leave it off

Is it that loading and splash screens been merged ?
that would explain why I cant get these nodes.

marble frost Jun 7, 2020, 12:37 PM

Is there a way to identify which motion controller the player is using? (Vive default, knuckles etc, as many players have vive but use knuckles controllers)

covert ferry Jun 7, 2020, 1:14 PM

#

I am VERY stuck here.
All I want to do is enable a splash screen so I don't have this sickness inducing/crashed looking screen when I move between levels.

But the documantation for it is all different and seemingly all out of date as I can not even get the nodes which are used in them. :/

covert ferry Jun 7, 2020, 1:50 PM

#

had an amazingly simple solution which worked and actually made my loading time near instant (the very reason I wanted Splash screen to start with)

sullen vortex Jun 7, 2020, 2:25 PM

#

@marble frost you will find how to implement that in VRE plugin

marble frost Jun 7, 2020, 2:27 PM

#

@sullen vortex the OpenVRExpansion plugin has functionality to detect the headset, I was not able to find anything that could detect the controllers, I will keep looking though, thanks a lot

sullen vortex Jun 7, 2020, 2:28 PM

#

look for where it loads the controllers profile

#

oh you want to detect controllers, not hmd, sorry

#

but if you know the hmd model you will 90% of chance to know which controllers is using

marble frost Jun 7, 2020, 2:44 PM

#

Yeah, that's why I mentioned about Vive users using knuckles 🙂

#

What I can do though, is that I can ask for the user to press trigger when the game starts and once they do that, I will get the info about their controllers

tired tree Jun 7, 2020, 3:07 PM

#

@marble frost it has an openvrcontroller type node now actually

#

Specifically because of Vive with knuckles started to show up

#

I actually have to go add quest on steamvr to it now that link exists

marble frost Jun 7, 2020, 3:09 PM

#

That's awesome, thanks! I might be using the older version of the plugin

tired tree Jun 7, 2020, 3:11 PM

#

@marble frost yeah I think that was updated in 4.23 or so https://vreue4.com/GeneratedDocs/OpenVRExpansionPlugin/OpenVRExpansionFunctionLibrary/nodes/GetOpenVRControllerType.html

#

You can use the gain and lost tracking events on the controllers to reinit if the players swap controllers mid game too

marble frost Jun 7, 2020, 3:13 PM

#

Perfect! 👍🏾

silver robin Jun 7, 2020, 8:21 PM

#

I’m probably missing something obvious but I’m out of ideas. I have a pawn set up with some components that follow the motion controllers; they show up, so far so good. the problem happens when I try to attach another actor to one of those components: it stays at the origin. if I pause the game, the actors are set as children of the pawn, but they don’t move. ring any bells?

#

is it because the controller components are the ones moving, not the actor itself, so the child actors don’t inherit any motion?

#

yep that was it. if I use “attach component to component” with the actors’ roots, instead of “actor to component”, it works fine

smoky valve Jun 8, 2020, 3:12 AM

#

@hallow knoll thanks for your reply. I opened the device output log and I see what's causing it. Not sure how to go about fixing it.

@lethal delta just those two. One of which is disabled.

Oh crap! haha, that's my other project.

Let me check the actual vr project :p

Okay yeah, those are both on each project. The vr one I'm trying to build has both disabled, so I don't think those would give it any issues.

silver robin Jun 8, 2020, 4:43 AM

#

is there a way to know whether the user’s set up their VR stuff for standing vs. room-scale? it looks like for the latter I can use the SteamVR chaperone vectors or Oculus’s play area transform, but I’m not sure what either of those will return if it’s set up as standing-only

lethal delta Jun 8, 2020, 4:47 AM

#

@smoky valve did you set up your android platform stuff in engine settings?

smoky valve Jun 8, 2020, 4:48 AM

Yeah, I've got all that setup.

lethal delta Jun 8, 2020, 4:48 AM

custom engine?

sorry only reason im asking is i remember getting the same bug and im trying to job my memory

smoky valve Jun 8, 2020, 4:49 AM

#

In fact it was running just fine in 4.24, until I upgraded to 4.25

#

No worries.

#

I also should note that I'm using the Human Codable VR Framework from the marketplace. But that's working just fine, so I doubt it's that.

silver robin Jun 8, 2020, 5:07 AM

#

this is in 4.25—I vaguely remember seeing some note about a change to how VR inputs worked but now I can’t find it

hallow knoll Jun 8, 2020, 2:48 PM

@silver robin It's pinned to this channel: https://docs.unrealengine.com/en-US/Platforms/VR/DevelopVR/MotionControllerKeyDeprecation/index.html

Motion Controller Key Deprecation

Overview of Motion Controller Key Deprecation and Migration

#

However I think that's unrelated to @smoky valve's problem. It seems like your project in 4.24 was referencing that file - As a test could you try to find it in the 4.24 version of your project and if the file doesn't exist in the 4.25 version, copy it over?

#

Are you excluding "Engine content" when packaging?

limpid widget Jun 8, 2020, 6:52 PM

Hey,

(Unreal engine 4.25.1)
I've started a new project (c++) and created a blueprint based on the vr template to spawn two motion controller actors, they are spawned and appear ingame, the only issue I have is that I can't control them.
I'm checking it with the vr template project but the blueprint and settings are the same, so I'm running out of ideas

#

anyone had this issue?

radiant garden Jun 8, 2020, 8:20 PM

#

@hallow knoll Does that pinned deprecation note mean you are supposed to use something different than the project Input Actions to get button presses from motion controllers?

sturdy coral Jun 8, 2020, 8:36 PM

@limpid widget if using steamvr make sure you generated bindings etc.

hi there! somebody can tell me how to setup the Oculus Quest Thumbstick to be progressive? I'm using the input Thumbstick Up but it return 1 when it is press and 0 when it is released... (how to get the progressive values?)

#

i'd like to modulate a float with thumbstick...

#

working: i'm using MotionControllerThumbRight_Y now

hallow knoll Jun 9, 2020, 12:55 AM

#

@radiant garden No it means that you now have to use the Action/Axis-Input system

#

You have to set it up for it to work - You can no longer do "MotionControllerRightTrigger" directly in Blueprints

#

Take a look at how SteamVR handles it on the users end - It's pretty cool and allows controllers that were released after your game to be supported, either by you providing a new Action manifest or someone in the community if you're no longer supporting the game.

radiant garden Jun 9, 2020, 1:17 AM

#

Oh. You can bind the steam VR actions against the ue4 actions?

#

I'm new to ue4 but I did a VR prototype in Unity with steam VR

tired tree Jun 9, 2020, 1:20 AM

#

they are one and the same

ue4 exports its "actions" as actions for steamvr to fill in with buttons

Can anyone help me getting oculus mixed reality capture working? I have calibration and OBS setup completed and that all works with other applications.

#

My issue is enabling MRC in my game

#

This is on quest by the way

#

I have set casting and composition method and called "save to ini"

#

But I think the issue is the "get oculus MR settings" node returns null

#

So setting casting etc never actually happen

#

📎 unknown.png

#

Does the app need read write android perms to access its own directory? (surely not...)

#

reading docs:

bIsCasting (GetIsCasting/SetIsCasting) - Turns MRC on and off (does not get saved to or loaded from ini)

#

so this doesnt get saved? why does it need the MR object???

#

this is the ref oculus provide:

it runs through various steps, then get to deploying to quest which it seems to do fine and there's no errors before in any other steps

real needle Jun 9, 2020, 4:45 PM

#

right for some reason everytime I do that it keeps compile shaders etc but the amount it's compiling is stupidly larger and takes decent amount of time is there a way it compiles once

#

not each time I click launch ?

balmy scarab Jun 9, 2020, 4:47 PM

#

if you change renderer etc it will have to recompile

#

it should cache them

real needle Jun 9, 2020, 4:47 PM

#

so if I stick with volken on it should just compile once and then not again unless there new shaders it needs to compile ?

balmy scarab Jun 9, 2020, 4:48 PM

#

yeah

#

subsequent builds will be quicker

#

if you change some settings it will recompile them, like there are some stationary light settings etc, stuff like that have a global effect

hello everyone

#

I followed some instructions and tutorials to get unreal template vr working on my oculus quest, but when I launch the project, I only get black screen, have you had any issue like this?

#

I get "LogTcpMessaging: Discovered node '0077500F08D80CA039F97EE848BE790F' on connection '127.0.0.1:6666'...
LogTcpMessaging: Discovered node '007D253108D80CA03BF5F61848F151C6' on connection '127.0.0.1:6666'..."

Hey all! Does anyone know what happened to the Showdown VR demo? Epic released it way back in 2015, and a lot of their docs on VR reference it. I went looking for it to download the project, since they have an article that states that its "Free in the Learn tab" of the Epic/Unreal launcher, but it is no longer there. Then, when I did find it in the marketplace, it seems to no longer be available: https://www.unrealengine.com/marketplace/en-US/product/showdown-demo. Just wondering if anyone has insight as to why it was removed
