Hi guys, does anyone know how I can switch from non VR mode to VR mode in blueprint?
I want to load a level and start it in VR.
I tried the ConsoleCommand node "open levelname -vr", but it didnt work
warm lion
I Enable HMD and execute the fullscreen command
Just pull that off a begin play or something up front
serene haven
@warm lion Thanks I will try that.
One last question, does anyone know how to disable the SteamVR Input System?
I updated my project from 4.23 to 4.24 and the SteamVR automatically got activated.
@warm lion Thanks, your suggestion worked.
Strangely it only works in the packaged game but not in the Standalone version
warm lion
I rarely use standalone - sorry I don't know about that. I typically just use the vr preview and my builds.
serene haven
@warm lion yeah, seems I will follow your path here and only use VR Preview and the Build in the future
sturdy coral
@serene haven you should be able to switch to vr in standalone
there is one bug I have run into where if you enable VR on first game instance tick with the oculus plugin, things will crash
warm lion
@sturdy coral do you ever use set base position?
For offsetting the VR origin
When I runtStartLoc = PlayerRef->View->GetComponentLocation() - PlayerRef->Sphere_Collision->GetComponentLocation(); GEngine->XRSystem->SetBasePosition(FVector( -StartLoc.X, -StartLoc.Y, StartLoc.Z)); My vr origin is perfectly moved so that my RootComp, Scene Comp, and Camera, comp are all exactly where they should be, but the motion controllers attached to the middle scene comp do not move with the other comps. They stay where they were and inherit some relative offset that I can't tell where it's coming from
sturdy coral
@warm lion no I just move the vr root

Oh well yeah you have one of those fancy capsule pawn

Does anyone know how to disable the new SteamVR Input System?

Disable the SteamVR plugin?
serene haven
But if I disable the plugin, can I still use my HTC Vive?
tired tree
@serene haven you can't
its the input setup for steamVR now natively
there is no longer any use of the legacy input system
serene haven
Everytime I package a project I cannot use my MotionControllers. Even when I generated the InputBindings and the SteamVR Input manifest. The SteamVR Menu allways opens when the game starts and tells me that the bindings are not mapped to the inputs. Is there a detailed tutorial how to do this?

Has anyone tried to stream graphics unreal from a PC to a smartphone that is in sync with the pose of the smartphone ( Maybe using ARKit or AR Core?) ?
Using Wifi maybe?
Would be gest to have NVIDIA RTX power for the AR graphics you display on a smartphone
I saw Cloud XR demonstrated October 21st but haven’t got access yet.
So a powerful RTX PC rendering AR graphics for a Smartphone could be a fallbacl
If anyone has tried Cloud XR from NVIDIA it woulf be great to hear about it

@serene haven can't remember which file, but old versions of the plugin could have left something behind that needs to be cleared out
I think it is in one of the steamvr vrsettings files

@sturdy coral I also tried with a clean new VR project, even there if I open the packaged game, it tells me to bind the actions to the buttons

Hi Guys, i am relatively new Unreal user. I have been experimenting with the AR handheld template and i wanted to know if there was any way to edit the blueprint so that the replaceable spawn actor is spawned only once in the scene instead of it being spawned with every touch. Any help would be greatly appreciated. Thank you.

cant remember the BP exactly @pallid osprey but basically u just find where the touch event is, and easiest is to put a DoOnce (or maybe its called RunOnce) blueprint before the stuff it does

how do i make the vr preview show my right eye?
sturdy canyon
I updated to the latest Oculus 4.24.2 branch
Now I can't play in editor with an Oculus headset
it just sits in the oculus home waiting for the app to display
Another possible symptom: When I launch the editor with SteamVR running, I get taken out of SteamVR and sit in the oculus home waiting on UE4
The vr preview view pops up and the view is tracking my head, but inside the headset I just see Oculus Home waiting on my game
Also my hands aren't tracking in game
Hmmm.. I disabled the SteamVR plugin and no UE4 greys out play in VR. So it's just completely unaware of the Oculus runtime
I bet this is one of those reboot my PC to fix things

magic bridge
anyone know what the ARplane geometry node "get subsumed by" does? can't find any real documentation on it
lofty oar
Hey guys if I had a physical virtual camera a vr user could operate, how could i record the camera position when recording? The date would then be imported into things like C4D to be used as the comp camera
woeful sundial
@magic bridge as the user moves his/her device, the AR system gets a better understanding of the real world environment over time. It eventually detects that two assumed plane-areas actually are one big plane, for example one big table, so these get merged together. One plane gets subsumed by another. In case you have a reference to a plane and later it is gone, you can find out by which plane it got subsumed by.
For AR work it is important to also check Apple ARKit or google ARCore documentation. The Apple talks at WWDC are very helpful, even if no XCode/Swift is used. These cover technical principles and guidelines for a good user experience.
Waiting for unreal to make a full documentation is hopeless. That is something our grand children might maybe witness.
magic bridge
@woeful sundial ah ok that was very helpful thanks
obtuse condor
Hey, Im working on a Blueprint AR project and I was wondering if there is any way to get the scale of Detected AR Planes.
Please help!
Im trying to spawn a Plane whenever I detect an AR Plane. So I to match the scale of the plane that I spawn with the scale of the detected AR plane
magic bridge
there might be a better way to do this, since im kind of new to it, but the way I've done it is to get your tracked AR plane, and then from that you can get its extents and origin
if your plane is a pre-existing static mesh you'd have to do the math to scale your plane to the new size, otherwise if your plane can be procedurally generated, you could feed your AR tracked plane extents into a "Generate Box Mesh", which would feed into a "create mesh section"
woeful sundial
@obtuse condor yes, like @magic bridge writes. use get extents.
if your mesh is 1 squaremeter at component scale factor 1.0 like the one that comes with in the ue4editor, it is very easy to calculate sizes. just multiply the mesh scale with 100 to get it's actual size in cm (100cm x100cm).
@obtuse condor @magic bridge UE4.23 and later can actually do this automatically also with collision, occlusion material, nav mesh... (enable in the ARSession Config)
Too bad ARKit camera footage is broken and we still have to improvise with 4.22... 😒
zealous vortex
I am working on a VR project and I need to get the position of one of the Eyes of the HMD (for camera placement) on C++. I have been looking at the tracking system, but I still couldn't get my head around on how to precisely get this position. It normally ends up with some strange offsets or overall incorrect world positions. Any ideas on how I can precisely get the position I need in world space?

when you join a VR multiplayer game and attach one object to the other and weld them, and a new player joins, what is the best way to replicate that attachment to the new player? we had problems where attached static meshes werent replicated as "attached" to clients that joined in later.
sturdy canyon
Are you using a dedicated server?
Make sure you set attached on server, not on a client
it shouuuuld be replicated
tired tree
yeah assuming the object is replicated it should just work
the caveat being that "weld" attachment doesn't replicate at all
so if its on a simulating object its not going to behave correctly
but the base attachment will still function

Are Instanced Static Meshes/Hierarchical Instanced Static Meshes supported on Quest? I have both of them in my project but they do not show up on Quest! Has anyone ran into this before?
last knot
the recent Quest firmware update added the auto-switch between hands/controllers. I like it, but it's somewhat annoying in that i set down my controllers and HMD, edit some code, click launch, put on the headset and it hasn't launched but instead is at a screen saying "this app requires controllers to use. pick them up and click here." Short of totally turning the feature off, is there some way to indicate in your app that you don't actually need controllers? (which I don't for what I'm doing right now)
mighty carbon
I don't believe there is away to do that in the app right now
but, you can either disable autoswitch in the settings or make sure you controllers are active when you run the app

@last knot you might as well post screenshots from Quest showing the issue. Not everyone will download and run your apk.

i didn't just post an apk, but an entire project. but unfortunately, screenshots are a bit tricky. it's a subtle, but noticeable effect with the headset on. it's a "shimmeryness". my coworker definitely noticed it
i'm going to send it in again with a video texture instead of an image texture, because they pretty much ignored me saying it happened with both and told me to change mips settings
also that it didn't happen when using oculus link

I really wish UE would properly track when you add new assets (like video files) and copy them over to the headset when it deploys. At least, in something other than a haphazard manner. Sometimes, it just doesn't work.

@mighty carbon I figured out a good way to get some screenshots. Here's a screenshot where the left half is from the "normal" material, and the right half is from the buggy material that is taking the right-half of the video texture:
You can see that the left half looks like the native source, and the right half has had what looks like anti-aliasing added

I am not sure.. Never seen such thing before (and I don't use video textures)

When I launch my VR game in steam vr (through a build added to steam) using an oculus rift s, the game launches but doesn't ever gain the focus in the HMD.

You can run session front end for example
If you're CPU bound session front end is great, you can put on and turn off stat commands through that too - directly to a Quest's dev build
GPU bound you'd need to use renderdoc or Qualcomm's debugger

Hello,
quick question : is it possible to run 2 clients and a dedicated server in the editor, but only have one of the 2 pawns use the HMD? Right now when I do that, both clients camera are updated
If that's of any importance we're using the VR Expansion Plugin https://vreue4.com/
from my researches on the web I think that is not possible but maybe things have changed by now

Since I use the SteamVR Input System, whenever I wanna launch a packaged game, it does not startr, any ideas?

@serene haven You need to assign a default Action Manifest for your game. I've done it but don't remember the exact steps.

I pressed all three options provided by this default SteamVR thing
Everything in the editor works fine, but in a packaged game only the HMD works but nothing with the controllers
Can I check if the menifest gets copied to the packaged game?
sturdy coral
@serene haven yeah, look for [packagedir]/[ProjectName]/Config/SteamVRBindings/

Is there no way to check if the user is in the HMD while using Steam VR? XRSystem->IsTracking(0); seems to always return true so long as the HMD is plugged in. Also I'm using a Rift S so I don't know if that causes problems or not. For Oculus VR I can simply call VrHMD->DoesAppHaveVRFocus()
What about the proximity sensor, doesn't the vive have one too? Is there no method for interacting with this?

@hallow knoll thats what I thought, and started to do. Thanks
serene haven
Is there a way to find out, why a packaged game (it is the vr sample project) does not want to start?

@serene haven "does not want to start" isn't enough information for us to help you troubleshoot

@hallow knoll I was thinking I could update the GameMode to spawn a VR compatible pawn for the first player controller to login, and regular pawns for the other ones
hallow knoll
I was able to hack that together in 4.19, but it only worked 50% of the time.
I have a (owning client) check in the player controller that determines whether it should spawn a VR pawn or a Flat pawn. It's configured in a way that if I hit "PIE", it will spawn Flat pawns, and if I hit "Play in VR", it will spawn a VR Pawn.

brisk spade
@serene haven nope start in VR
it should auto assign the default pawn to my Player Start, shouldnt it?
ok it gets the right Pawn, but the controllers are still on the ground
woeful sundial
@obtuse condor yes, possible. But better to create different actors for each detected plane. if you have all proc.meshcomponents in one actor, that actor will have a very big bounding box. Disadvantage: it will always get rendered, because some part will always be visible. If instead you have several smaller actors, the ones that are not in the view don't have to get rendered, that's better.
Next problem with huge actors with widely spread components is, that if the Actor location moves a bit because the AR system corrected it's place in the real world, the farer away that component is the more it seems to move to another direction. study Apple or Google documentation to avoid these design mistakes, this is a good start: https://developer.apple.com/videos/play/wwdc2018/805/

Anyone here use SetBasePosition while calibrating their play space for players? I've finally got it so my pawn components are not being moved out of the way because the origin was too close. But now my motion controllers will not update their position even though the component they are attached too is in the correct location and the camera has since moved away they do not track where they should be.
I've already created an extended camera class to get the camera + origin where I want, it looks like I'm going to have to do the same for the motion controllers.
I can't even set their relative locations to zero they still just exist way out in space away from their parent

Hi, I'm pretty new to VR in Unreal (I'm using a Quest for development and a Rift for quick previews). My question is how can I apply gravity to the MotionControllerPawn? I've seen suggestions online to change the base class to Character. However, when I do that, my hands disappear and while I can still teleport, the teleportation controls are not originating from where my hands should be. How have you all handled gravity for your player?

AN ANSWER:
By default mobile uses half precision in pixel shader calculations to improve performance. You an either perform the texture coordinate math using full precision by checking the "Use Full Precision" checkbox in the material (under Mobile), or by using a Customized UVs to perform the UV math in the vertex shader, which always uses full precision, and passing the result to the pixel shader. There's an extra nuance for external (media) textures which can make them use half precision even when using Customized UVs. If you notice this, use the Full Precision checkbox.
i don't know if they would have added that if I hadn't prodded them by email again. i'm going to try it right after I get back from an appointment and let you guys know
wound up having a little extra time. that fixed it! Geez. Not a bug, but a feature. I see the logic, but that's a hell of a gotcha

Here is another Quest (or perhaps XR in general) bug to vote for https://issues.unrealengine.com/issue/UE-88768
In the e-mail to me it was said that it's not a priority to be fixed 😦
as if Epic doesn't really have much love for Quest
tired tree
i mean..thats not really that high of a priority though....
there are muuuch worse VR bugs in general currently
mighty carbon
sure, but according to Oculus rendering non-mipmapped sky is a waste of computational resources, which aren't great on Quest to begin with (on PC it doesn't really matter)
in fact, they can just make it mandatory for every texture to have mips (I know Carmack was adamant about that)
so, it kinda is a bug in the critical spectrum for those who aiming to release on Quest through official store

last knot
yeah. but if they want to give people a reason to choose Unity, things like this are a big help 😄
mighty carbon
I don't think the pool of devs using UE4 for Quest and bringing in $$$$ in royalties big enough for Epic to care
and somehow Oculus doesn't seem to have same kind of relationship with Epic as they do with Unity
last knot
I'm talking more cross platform, or what to settle on as a shop
if we can't effectively do our Quest stuff on UE, then we'll just go unity for ALL our VR stuff
because people can get the best at one tool
mighty carbon
true, but what I am saying is that it's irrelevant to Epic IMO 🙂
last knot
I get that. I just think it would be shortsighted of them and have chain reactions that would be relevant. Unless they just want to cede the entire VR space to Unity
mighty carbon
nah, I think PC VR is supported quite well in UE4
last knot
i think you missed my point, though
i'm not saying PC VR isn't well supported in UE
I'm saying even if PC VR is well supported, if mobile VR (specifically Quest) isn't well supported, and mobile VR is the hot VR that shops are wanting to make products for (either by itself, in addition to the PC VR products they are making, and/or as ports/reimplementations of their existing PC VR products) and UE does NOT support it sufficiently, then shops will choose Unity because they can get things done on all platforms
hiring/training people in Unity instead of fragmenting it between UE and Unity (because they have to use unity to not suck on Quest)
sturdy coral
@last knot if/until oculus opens their store more broadly it doesn't make sense for epic to support everyone using quest, except the few studios that can pay for support contracts
because they are the only people likely to get accepted anyway
last knot
i get what you're saying, but you're focusing on Quest as if it's an island
our shop is getting into VR, and how well the engine works across all the devices is what's informing us trying to figure out which engine to standardize on
so far, I FAR prefer working in UE. But if I have to say "but it lags behind on quest when it comes to features and bug fixes", that's going to sway the decision to unity
sturdy coral
basically oculus should probably do all the engine support for quest, since unreal's indie model doesn't really even work with it as no one can get accepted, but I guess oculus already does the support to a big degree with their branch
fair hearth
Doesn’t oculus have their own branch of unreal anyways? Does that have any quest specific features/bug fixes?
sturdy coral
yeah they do a good many fixes in there

@fair hearth mostly their SDK related

Atmospheric Fog does not handle MSAA correctly yet. forward renderer, has this been addressed yet?
@sturdy coral Ambient cube maps (HDRI) do not work in FR.

@quiet badger not sure, thought you were wanting to use something close to fortnight though (uses deferred)

for VR
i suppose I could do deferred since the art style doesn't change the materials between both render version. Just not sure what I'd do to make deferred less taxing
sturdy coral
@quiet badger you probably do want forward, the main limitation with forward I have found for landscapes is that light functions don't work correctly for stationary directional lights, so things like cloud functions don't work right. but for fully movable I think it works

Bug Fix: Fixed lighting/volume fog rendering incorrectly with stereo-instancing enabled by ensuring the correct fog volume texture is referenced when sampling fog. fog got fixed in 4.24 for VR apparently

does anyone else consider taking off and on the HMD over and over and over through the course of a coding day one of the most annoying and sometimes headache inducing things they've ever done in coding?
at this point I REALLY want a fake HMD that can just be the tracking stuff with the wiring for the panels going out to a regular screen or something. SOMETHING. just where I can leave the damn thing on and code

Like that bug, for one. Or this thing I was just doing where all my textures wouldn't work, which I'm pretty sure is from trying to load too big of a movie texture in. Works fine on Link. Other stuff is super duper slow over Link
And even with Link, you still need the HMD on your head to have the motion controllers in the right orientation to manipulate stuff even if I was watching on a monitor

@tired tree but how can you test motion controllers and interactions in 2d?

most can be tested in 2d fine

Nah, never thought of trying it.. I thought it was for a non-VR game

nah, just launch not in vr
and its the same pawn, but with the hands locked to your camera
for quick tests
then if you launch into vr its the VR version

it would probably help if I had a counterweight. coworker got a powervr and he says it works great for that.
makes it much easier to just leave it up on your head

sorry, VR Power
mighty carbon
What's that?
last knot
it's a little battery pack for the Quest that extends it out to 8 hours-ish. But the nice side effect is that it acts as a counterweight for Quest's front-heavy design
Which is a big part of why it's annoying to just leave on my head when coding. You really have to work at balancing it.
My coworker has been building stuff using the new quest hand tracking. Especially hard to do that in 2d 😄
tired tree
@mighty carbon yeah its a lot worse when you are just iterating over something initally
last knot
We're just doing a lot of learning. Ideally, we'd start on doing JUST PC stuff. But we're a company that lost our main business and now we're just throwing VR at the wall and seeing if we can pivot the company towards that before deciding whether or not to shut down.
So lots of pressure for something to show the boss that's actually in VR, and doing stuff that you uniquely need VR to do.
I've been coding for over a couple of decades, but never really touched a 3d engine in a serious way before last fall
Much less built anything for VR.
mighty carbon
Ouch 😕

Enh, it's not so bad. It means we get to take all the code we've been trying to staple features and bug fixes on for the last 20 years and fire it into the sun.
So there's some upside. 😄

Well, THIS job, yeah. But I'm not too worried about finding another.

It's a pretty good market here right now, especially for experienced coders. I'll probably not find as sweet of a setup as I have right now with a small company with a flat management structure that consists of one single boss that's the company owner, where I can telecommute every day. But I won't go hungry.
And I've always wanted to build some of the numerous game ideas I have had in mind, so I'm getting free work time to learn 3d engines for a few months at least. Will make that a lot easier to do.
I suspect I won't have anywhere near the skills to be useful in a job that's actually 3d/VR focused, though
Will probably have to go back to coding boring business apps
mighty carbon
That's where the money is in

@last knot so you build a test character that doesn't need the headset, at the same time you could bounce off that character to make a non VR version of playing the game. Cross play if it's multiplayer.

is there a way to manually force an ARsession to reset tracking? I see the enabled flag in the session config but some times I find that the tracking goes haywire
@magic bridge
yes, run StartARSession again, choose a session config that has the flag (reset tracking) enabled. This is normal workflow in swift for ARkit too: No need to stop the current session, just run again StartARSession with another ARconfig.
Best approach to avoid these bad tracking cases is to not start any game before GetARWorldMappingStatus returns "mapping, relocalizable" or "mapped". Current mobile AR tech requires communicating to the user to move around a bit at the beginning and find a well-lit space to play.

So I came here to ask a potentially silly-ish question :/ about VR.
i've been growing more n more interested in VR. Im thinking of getting into it 'casually' but I am worried it requires LARGE sums of time and something you have to really commit yourself to. Is this true?or is it like learning any new skill as in nothing EXTREMELY difficult
I guess why i am worried is due to the lack of resources out there . I know decent C++ and pretty good BP. I know the real commitment to VR is purchasing the headset but i meant after that.
tired tree
it requires different through processes
and is more tedius to dev for
but as far as significantly harder than a normal game? In many instances it is much easier
rich canopy
Its fun to prototype if you are not making a game to sell
tired tree
if you set things up correctly you don't have to teach players to play, they just do, you can create natural interactions
once you have a framework, things just fall into place
I think your setup time is the most important investment with VR
mighty carbon
Damn, so many posts... what did I miss? 😅
dry python
@tired tree thats what I think is so cool about VR....natural interactions. Just the player doing their thing.
@rich canopy oh really? why do you say that? perhaps because not many people have VR headsets therefore its much harder to generate revenue from such games?
in regards to the headset. i'd do huge sums of research before committing to a particular headset. but yeh the dev part of VR is a little intimidating
rich canopy
Ya definitely. Also making something really polished to sell isn't a casual thing.
tired tree
again though
the polish expectations are still rising
its not a field with 40 years of prior expectation attached to it yet
if anything, indie games with good gameplay have a higher engagement in VR than out of it, though the market is far smaller
dry python
yeah i see. would you say that due to the limitations of VR, the 'gameplay' tends to be simpler? and the expectations are lower because the audience understands this? [not trying to belittle vr or idk make fun of it]
tired tree
there haven't been good enough games in VR yet to have the expectations of AAA 2d
we'll see post Alyx, Boneworks set some standards a bit higher for sandbox already
as new bars are raised the expectations go up as well
dry python
ah yes true those two games do look great

you might try this one:
https://www.amazon.com/gp/product/B07D7NTJ1D/?th=1
a coworker and I both have the 10ft one (which is out of stock - I wonder why) and they've worked great with the Quest
he has the official Link cable as well, but switched to this one because the official one was so damn heavy
but if you use it, I'd suggest tying it down to the strap since there's no right angle on the port. So it puts a fair bit of wiggle on the port if you don't. I'd probably do the same with the official cables, though. It's not good for that part to be the one that gets a good bit of stress, which they will if you're a dev

@sturdy coral thanks. I found that there WAS a big buck bunny video for over-under, but unfortunately it didn't expose the same bug some other videos did.
it's weird, if I just display the top image, fine. if I just display the bottom image, fine. If I put them together and make a stereo image, each eye gets a different set of hotspots on some parts of some videos
like these red splotches
but it's not the video, since they plain fine in oculus gallery and pigasus. must be something in my code

okay, so I'm playing stereoscopic video, and I think I got everything right. The only oddity is that these artifacts keep showing up in 3d, but aren't in the video when you plan just the left or right channel.
this is on the Quest, btw. This is what the material looks like:
the artifacts are as if bits and pieces of the image are "ghosted", with the color shifted. so the red HARIBO logo gets some greenish yellow ghosting
and you can see it on various other parts, too
and you can scroll back a bit and see the other pic i posted showing the womans face with the red artifacts on it
sturdy coral
@last knot lerping between two texture reads is much more expensive than you would probably want for quest, instead take texcoord * [0.5, 1.0] + (stereoeye * [0.0, 0.5])
the way you have it is going to sample the texture twice
should also be able to make it an unlit material and instead of having base color
last knot
okay. but do you think either of these things is what's actually causing the artifacting?
sturdy coral
no, I don't think so
last knot
also, just to sanity check: for side-by-side, you mean texcoord * [0.5, 1.0] + (stereoeye * [0.5, 0.0]), right?

as in, in the exact same places
last knot
got the tweak you suggested to get rid of the lerp. thanks again for that. I had zero idea how to get stereoscopic working and was following advice on answerhub or the forums
yeah, the artifacts are 100% repro
sturdy coral
@last knot maybe this is it: "Although Oculus Quest and Go can decode high-resolution video up to 5760x2880 / 30fps, some encoding workflows can result in the export of files that show visible corruption artifacts when played back in Oculus Gallery, especially when encoding in h.264 with long gaps between iFrames.
The reason for these artifacts is that motion vector range (mvrange) can exceed levels permissible by the h.264 level 5.2 specification, and video encoders can open mvrange to level 6 [-32768, 32767] when encoding video at the high resolutions that fit into level 6. While the video decoders in Oculus Quest and Go allow for resolutions exceeding the level 5.2 spec, they require that mvrange stay within level 5.2 compliance [-2048, 2047]. When encoding h.264 using libx264, ffmpeg allows for level 5.2 mvrange compliance by using the arguments, "-x264-params mvrange=511". mvrange needs to be under 512 to be in compliance."

oh, sorry, i didn't note this now but i did earlier: the videos play back fine in Gallery and in Pigasus

Hello all, I'm moving over to Unreal from Unity, focusing on VR development (on the Quest). While I am still in the "learning" stages, I've gone through enough tutorials (and Blueprints Udemy class) that I want to create a small project for myself and to hopefully demo to some others. The project I want to create is a "scared of heights" simulator where the user climbs up ladders, etc., several stories tall, and maybe traverses a catwalk. I know there are some height simulators out there, but this is more for my learning experience. So here is where I'm a little stuck getting started: are there any good tutorials/courses out there on creating large scale environments which are also performant in VR like the Quest? I say "large scale" because when the user is climbing up, they need to be able to look down/around and feel as though they are above everything. Thanks for your help!
sturdy canyon
Rendering performance is determined by number of objects, total vertices, and shader complexity.
You can make things bigger by scaling them up and they will not cost more to render (except that they may take up larger screen space and thus require more pixel fill)
hallow oxide
So I'm trying to use 3D Widgets to allow for a component to be tied to the player's left wrist in VR, and it's rendering more or less backwards (which I feel like is caused by the fact that the rotation of the widget is tied to the rotation of the wrist)
For reference, it's supposed to look like this; the widgets I want players to see will be smaller than this one of course, but they're all rendering backwards when they rotate to a direction visible by the player and I'm not sure how to fix it
sturdy coral
@hallow oxide one of the hands is mirrored in scale to turn it from left hand to right hand or vice versa, when you attach set attachment flag 'not including scale'
if it happens with both hands it is something else though
hallow oxide
How would I set that flag? @sturdy coral
sturdy coral
in cpp it is in FAttachmentRules, it is exposed to bp too somewhere
hallow oxide
I gave the left hand its widget actor using add component, and I was told by the project maintainer that the left hand (which the widget is attached to) mirrors the right
All of our project code is in BP
sturdy coral
@hallow oxide you can set manual attachment, then attach separately with the ignore scale rule
or just adjust scale of X, Y, Z until you find the one that flips it back the right way
(change each to -1 one by one until you find which one you need)

I'm getting so tired of stubbing my toe on doing the right thing, but it doesn't work the same way (or correct way) on the Quest
Latest one, if anyone has any suggestions: if you have a MediaPlayer hooked up to a MediaTexture and Material, and that material assigned to some surface, you can play video on it just fine. But when you Close the video, in THEORY, if you have MediaTexture.AutoClear set to true, it will replace the last frame on the video with the ClearColor value. So you stop the video and instead of getting a freeze frame, you get that color. Works fine, over Link. Doesn't work at all on a native Quest app. 😦
Does anyone know if - like the issue with Materials not being full resolution on mobile unless you go out of your way to turn on a specific setting - there is some way to make this work properly on Quest?

The proper solution is to use a stencil mask, but I don't think I'm smart enough to figure that out

Hey guys, I've been doing a lot of research on headsets/equipment for VR. This is what I've seen:
- Oculus Quest seems to be one of the better ones . no wires. sharp display. but has lower refresh rate. around $500
- HTC VIve . has external sensors. good quality. around $500
- **Oculus Go **. really cheap. apparently good for 'noobies' wanting to see if VR is worth it? around $150
- Oculus RIft S. seems to be around quite good? uses physical cables and has lower res than Quest.
In your opinions, which headsets do you think is good for UE4 devs like myself who are newcomers in the world of VR?
EDIT: Any info or resources would be appreciated
slim karma
for developing I liked the Rift or Vive. I usually felt that the Rift offered a slightly better image quality while the Vive had superior tracking. But this is in regard to the original versions of either headset and overall the differences were minor. But if you have the space and the money, go with the Vive, or these days maybe the Index, but I haven't used that one so I can't give a good verdict on that. Overall I guess developing on headsets that are wired you'll have an easier time iterating though your problems, I think. Not sure how easy it is these days to test your project on a wireless or standalone headset.
Just my two cents and personal opinions based on the experiences I've made.

it's not about what HMD is good for UE4, it's what market you are aiming at @dry python

and using Oculus Link can work as Rift S when connected to PC

Yes, I'd definitely be going Consumer Market. "using Oculus Link can work as Rift S when connected to PC" -> Thats a good point!
I'd say since I am atm a hobbyist (although am considering a career in VR [not that there are an abundance of jobs lol]), i'll start with the quest
carmine yoke
@mighty carbon Depends on the enterprise, at scale index doesn't really work because of the effort of setting up the rooms, My company's moving toward quest/mobile VR just because of the ballache of setting up kits on site
dry python
@carmine yoke but you would also agree that Quest one of the better HMDs?
tired tree
its one of the better development HMDs, and also a very accessible platform
mighty carbon
@carmine yoke that's true, but you want more precise tracking that doesn't depend on lighting conditions, widest FOV and high resolution. Index offers that. Might not fit every single enterprise case, but mostly can cover a lot of ground so to speak
tired tree
"better" being subjective in other areas
dry python
Yeah I guess I mean one of the more all-rounded HDMs
tired tree
you'll need one regardless if you ever intend to target the platform, and its the largest user base outside of psvr
mighty carbon
@carmine yoke I think Rift S + backpack PC would be the best enterprise option where you need total freedom of moving around and quick setup (but then you are screwed if client has odd IPD ).
tired tree
eh?
even in that case why not quest
you can always cable link it to a backpack
can also run multiple setups, backpack and without
mighty carbon
@tired tree well, I've heard some folks say Rift S is more comfy than Quest (I haven't tried Rift S, so I can't say) and has higher resolution displays
tired tree
rift S is pretty bad fitting for me
not a fan of halo though
and doesn't quest actually have the higher res display? its just not ran at full
mighty carbon
oh, I see.. Yeah, I suppose Quest would be the "best" option then
mighty carbon
Best Buy had some yesterday, both 64Gb and 128Gb models
cosmic shoal
cool

to develop for VR I'd go with a RiftS, better screens and refresh rate, if you are gonna develop with the Quest you'll need the cable, a quality one costs around $70 otherwise you'll be compiling or streaming somehow.
carmine yoke
Yeah Absolutely @mighty carbon, we used to be on vive pro wireless, we're probably going to move to having a low end 'off the shelf' with the quest and a high end vive pro + kunckles so we can mess with the finger tracking
Scaling with VR is just such a problem
For niche cases, where you're doing everything in house and you want it to look and track amazingly yeah 100% go for vive pro/index with knuckles
I don't really see a use case for rift s/rift in business because you might aswell use the quest at that point tbh
mighty carbon
@cosmic shoal simply not true
I can't say I see too much difference between CV1's 90Hz and Quest's 72Hz in the same game (when using Link with Quest)
cosmic shoal
The quest is very portable and the setup is great, but unless you are are on a cable or streaming (both have dissadvantages) you'll have to use the on board processor/gpu that is about as fast as a mid range 2010 laptop.
mighty carbon
and so difference between 72Hz and 80Hz even less noticeable
carmine yoke
@dry python The quest is really good, accessible, and you can use the link for quick iteration and debugging. Getting an app on quest store would make it way more accessible to people too. Just bare in mind devving for the quest requires alot of optimisation/trade offs which aren't nearly as big a problem as devving for a high end desktop
mighty carbon
@cosmic shoal I doubt any hobbyst will be making something like Stormland or Lone Echo, so whatever they will be making might just work very well on "underpowered" Quest.
cosmic shoal
It totally depends on what you want to do
if you want to create something like job simulator, superhot, beat saber, sure. If you want to creat photorealistic arch-viz walkthroughs you'll suffer.
mighty carbon
$399, works as powerful mobile VR HMD and very good PC VR HMD (can develop and play for/on both platforms).. It's quite a no-brainer when it comes to choice between Quest and Rift S
carmine yoke
Plus there's gonna be a Quest 2 before we know it
carmine yoke
Yeah fine - but they already tried to make it with a better processor they just didn't get approval
Pico have one with a better processor, and eye tracking already
Just saying we'll see the technology jump at some point
cosmic shoal
I tried them both at OC6 and I could totally tell the difference between the riftS and quest even while using the $70 usd cable.
mighty carbon
Pico has no platform.. Tiny pool of devs too.
carmine yoke
I'm just being hopeful 🤷♂️
mighty carbon
@cosmic shoal well, maybe you are special.. Market numbers say Quest > Rift S..
cosmic shoal
If anybody asks me what headset to get I'll tell them Quest. (unless you have a good pc already)
but the experience is better in the Rift, just not as convenient/cheap
carmine yoke
@dry python Oh another thing you need to consider is ease of devving, I use quest at my desk with the link cable, with OG vive or rift you'd need sensors up, massive ballache
Rift s / cosmos (fuck the cosmos) you can use the inside out
dry python
@carmine yoke Your comment about devving for quest and optimisation/trade offs, isnt that for VR in general? Or are you saying specifically for the Quest in comparison to other HDMs?
in regards to the set up thats also a good point, i thought about it and i honestly didnt mind either option. as in I'd pick whichever HDM is more accessible/popular and is of higher quality whilst also not obliterating my bank account
btw i appreciate all this info! thank you
carmine yoke
Quest specifically, the power is so low compared to a high end PC, can't use post processing at all. Can only have 100k tris / 100 draw calls (give or take), Can't use complex shaders, gotta keep texture resolutions down. Some things straight up don't work on android because of bugs so you need to find ways around them. But that's only if you're devving for quest. If you're using quest to dev for PC then its irrelevant. You do need to keep your game optimised in general but there's alot more leway and choice compared to the Quest
tired tree
if you ever intend to dev for the quest you need one
so it with a link cable is the best dev headset
if you can only have one
tired tree
obviously, multiple headsets is better
i dev almost entirely on index
just because...its great
carmine yoke
Anyways, gotta get back to work, in a bit lads
cosmic shoal
I use a regular Rift at work and an Odyssey+ at home.
dry python
@carmine yoke ahhhh ok . I understand now. wow. i completely forgot that the Quest system doesn't need a PC . thanks for all the info. i'll def be devving for PC
last knot
and if you want to dev the same app for Quest and PC, starting with Quest and moving to PC will be easier than the reverse.
cosmic shoal
You should target the Quest market for sure, it is huge and growing. The developers of Superhot talk about how they optimized it for Quest https://www.youtube.com/watch?v=hr35o5R7EMA
dry python
@cosmic shoal thanks for sharing. i'll take a look! 👍
last knot
Yeah, they basically had to rebuild it from the ground up. It's a lot easier to add features, code things the more "lazy" way, and add general bloat than it is to take any of that away.

I swapped out all my default lit pbr shaders for unlit ones with phong lighting
And I’m using Vulkan. So I can afford lots of tris and lots of draw calls
~350k tris on screen and 170 draw calls maybe
I haven’t measured draw calls lately
I actually should be able to afford a lot more triangles now too
A bunch of Vulkan perf bugs were fixed in the latest OS update
mighty carbon
that's you though.. Vulkan is shit on Quest with Oculus' UE4 fork.. It's sooo bad that I can't even do anything with it. ES3.1 on other hand is blazing fast.
