Hmmm, I'm having troubles launching to Quest 2 on 4.26, Anybody know what problem could be here? I get a build fail on app:compileDebugJavawithJavac

Any Mac users here? Is it possible to Play using Oculus Link instead of having to compile each time?

I could be wrong but I've heard you have to dual boot into Windows

@idle osprey thanks! so sad to see it go with the introduction of M1

idle osprey
#

Yep...tho I am told it works with Parallels.

#

I cannot vouch for that, tho. I bought a new PC laptop. :(

dire lion
#

@idle osprey unfortunately windows for ARM has a different license agreement that prohibits it

#

so unless they change the license its not going to happen (legally)

#

has anyone had issues where the rotation of the teleport controllers (and subsequently hands) changes between running in oculus and steamVR?

#

I am finding that on steamVR the rotation of my controllers is all screwed up, but on oculus it is fine

#

can't seem to find the cause

Hey all, I got some animation sequences I made for the right hand on the default SteamVR hands, and I'd like to create a mirrored version targeting the left hand model. In the default project both hands are completely separate, with different animation sequences and all.
Is there a straightforward way to do this, without having to manually create each pose (and future ones) for each hand individually? https://puu.sh/GWt1S/2dac4f1de0.png

#

(I don't know how much that screenshot really helps, but I'm trying to mirror over the two animation sequences (static poses, really) pointed to by the green arrows)

sonic lake
#

@willow trail not sure it is possible within the editor to take an animation made for a skeleton and apply it to a mirrored skeleton. You can try to retarget it from right to left, but very likely it won't work. In the standard VR template the left hand is just visually mirrored, but the skeleton and animations are still those of the right hand.

#

You probably need to implement the workflow in your DCC tool of choice.

willow trail
#

@sonic lake Hmm, yeah sorry I'm using the SteamVR template, not the default VR template, guess they do things differently

#

Can't afford to lose too much more time on this, guess I'll go and manually repose 😕 I can't imagine just using the retargeting tool would work

sonic lake
#

Yep, you would probably end up with a left hand with the fingers curling in the wrong direction.

Hi there, I have some issues with the launch of "Play in VR".

I have the plugin oculusVR and SteamVR activated in my project (I would like to propose the two api on steam in order to be able to satisfy a maximum of users and possibly add the live HTC one in the future).

Is there a control console allowing me to choose on which SDK I want to launch my game? Or an option can be chosen as long as it works.

#

If i disable OculusVR in runs on Steam then, but it's the only way I've found. I don't think it's the right way ...

steady sparrow
#

This answer from two years ago seems to be close to what I am looking for, however it has no effect when I am in the editor. I would like to test both api in my tests.

Thank you in advance for your answers !

#

@steady sparrow did you launch the editor itself with that option, or just try to put it on pie launch parameters?

steady sparrow
#

On pie launch parameters. But i notice some time after that it concerns only standalone game.

#

I will try to launch the editor itself with that option to see how it works

#

If i launch editor with hmd=steamVR, then VR preview will be steamvr ?

Hello

#

Just joining and been thinking about trying this out. I have a friend that's wrote a book and working on another, so I thought of possibly trying to put it into a game as an RPG. I havent played with Unreal in a long time. Any tips?

steady sparrow
#

@tardy thorn I would personally recommend you not to start by starting a VR project. I begin mine more then two years ago and we are two engeneer

It's my first video game and there are already enough complications to add to it with virtual reality. Try to make a simple and not too long project to start with (why not a very simple platformer ?) and already meet all the difficulties you'll face on this little project from creation to packaging and then decide whether or not to go for it.

I started without having enough knowledge at the beginning with no idea that RV would slow me down, that multiplayer would slow me down and that physics with networking is even more difficult.

So now I'm paying the price.

Don't make the same mistake.

tardy thorn
#

@steady sparrow thank you for the insight on that. I know it's not going to be easy, but I also wanted something that had more of a polish, but I understand. So my first task is to understand and develop my skills in organizing my assets, packages, and other backside of the project more than jumping into the whole story side of things

steady sparrow
#

@sturdy coral Btw is there a newer version of Steam VR plugin ? I have the same since 2 Y and don't find any information about downloading a new one 😮

📎 unknown.png
tardy thorn
#

@steady sparrow of you need a tester, I'm a good critic lol

#

The only real issue I have in the side of the VR is just the damn adb crap

steady sparrow
#

@tardy thorn What I want to say above all is that learning everything at the same time will be very time-consuming.

UE4 / 3D modelling (if you have to) / Texturing / Skletal Mesh animation / Programming / VR

It's a lot of information to find and assimilate. And I warn you right away, there is documentation, but it will often be incomplete and you will have to search by yourself on the forums or for example on this discord (Something I still don't have a good knowledge i think... ).

#

adb is for android ?

tardy thorn
#

@steady sparrow almost everything I've been trying to learn over the past 2 years the document always seems to leave stuff out LOL. well I don't plan on designing everything from scratch I know for a fact he will probably be dumping some money in to help with other assets he's already been talking to a few software engineers. I'm a truck driver and a full-time college student and just try to find something to learn to keep my mind going and so I figured I'd give this a try since I have been learning a few different languages and linux, I didn't have any real goals or projects to focus on until he brought up his book. So now I have something to put my mind into

steady sparrow
#

It's a nice project in itself. And I think that video game programming is really the programming I like.
But it's hard, it's a reality for me.
Maybe for others it's easier, but personally with late planning and stress I don't always sleep very well.

That's why I advise you to try to test your skills in a small project before embarking on a long term commitment.

#

But you should listen to the opinions of others if they respond to you. Like I said I'm only two years ahead of you, there are guys here who have 15 years of experience there I guess.

Hello there, iam developing an app for the oculus quest. Since some time a have a problem running my app on the device, after a very long loading period the screen just stays black. Since i did a lot of changes iam struggling to find the error source. Is there some kind of log on the device that might help to localize the error ? Today it compiled roughly 9000 shaders, maybe some shaders cause the problems. Any advise is appreciated, thx in advance!

Hi!

I hope someone can help us out here. We are testing out the AR stuff on iPhones and iPad, and world tracking runs perfectly fine. However we are running into a "slight" issue with Image Tracking.

When using World Tracking, we place an object on a tracked plane, and we can move around just fine. However, if we use Image Tracking, the object is spawned on the image, but appears "stuck" to the camera. Even though we can see the tracked image visualisation in the correct position and scale as we move around, the object is stuck to the camera, not the tracked image.

A post mentioned to add a gamemode and pawn to the level, we did that but no changes at all.

Trying to modify the original AR example template.

When using Widget Interaction, sometimes it works with the button, sometimes it doesn't. What gives man....When I first load in fresh, it works, I can interact with my main menu no sweat. I choose a level, del my char, load in, spawn char. Once Im in the level I click button, spawn BP with Widget Component. I try to interact with it and nothing. Bloody nothing unless I button spam...sometimes

#

Any tips?

#

The only thing I can think of it's a bad pointer somewhere and destroying a old pawn and spawning a new one mucked with it

#

OR is there a widget visibility setting im fucking up on?

Ok so ever since upgrading my 4.23 AR project to 4.26, I am curios as to what material to use for the pass through camera. I see there is a new component for updating the pass through, which I have on my player pawn, but don't have a clue on what exactly to do

#

Also, I am now getting a ton of slowdown only when running AR that was never there originally

#

(note my project uses a modified version of the AR template)

wind yacht
#

I realized that the template project also runs at a lower framerate, so it dosn't seem like its a problem only on my end.

hello! having some issues getting instanced static mesh component to work in both eyes on the HoloLens2. I think it would also apply to anything that has two eyes or an HMD. Some of my meshes will work in both eyes but most of them are spawning and then only work with only one eye. I have seen a few posts about this and have tried disabling the Instanced Stereo in Project Settings but that didn't seem to do anything. Any help would be greatly appreciated. thanks!

Hey, anybody know why I would get "Game keeps Stopping" crash on Quest 2 and how to debug it?

sonic lake
#

@tropic kestrel you need to collect the log files from the device and see what is causing it.

royal plume
#

Does anyone know of a way to get the HMD orientation and position directly (not just having a camera tied to the hmd and using get transform)?

#

and possibly how to set a camera to only be tied to rotation and not position or vice versa?

magic bridge
sonic lake
#

You can unlock the camera from the HMD and handle it manually. By doing so you lose the low latency updates though.

#

@magic bridge It's rough to get going on AR with 4.26 since there's near no to zero documentation on a majority of items to get it going. I think I got my project up to where it needed to be mostly by looking outside the docs 😦

yeah it's most unfortunate 😦

Anyone tried out Raytracing + VR? My small bathroom scene has 17ms being used by RTX reflections. Just wondering what others are experiencing.

royal plume
#

Does anyone have any advice on how to create a system that checks for certain motion controller gestures like swinging arms back and forth to trigger an event? My initial thought is to use colliders and checking to see if they're being triggered in the correct order for the event

urban igloo
#

@royal plume Save yourself the effort and look for one of plugins/marketplace assets.

royal plume
urban igloo
#

@royal plume It's tempting, but we don't need to reinvent the wheel. I haven't actually tried any gestures in VR, so you might end up having to do it yourself anyway.

royal plume
#

yeah, after doing some searching I can see some plugins that would do what I would want from the looks of it

tired tree
#

really depends on what you are trying to do with the motion, locomotion threshold or just checking actual gestures, but its conceptually fairly easy for one, and harder for the other

#

@royal plume

royal plume
tired tree
#

@royal plume sample the velocity over time and low pass filter / average it on Z axis generally

#

set a threshold where it starts to take effect

royal plume
#

so this approach checks against a velocity pattern instead of a positional one?

tired tree
#

@royal plume velocity over time lets you get the ramping motion, also lets you scale speed by the movement

Hello all, I replaced the bsp I was using as the ground by a mesh of 400 by 400, and I modified the material (Ground Grass starter content) to have a consistent scale. In the editor it's ok, in vulkan preview too, but when I launch or package on android (oculus quest to be precise) using ES3 or vulkan, it's completely pixelated. I'm out of ideas, what do you think of this ?

@wind yacht I can help you with the passthrough setup if you're still having issues

candid viper
#

@viscid aurora Quest and Quest 2 by default run in a different colour space which over saturates. There is an Oculus function SetClientColorDesc - if you set rec709 that is very close to sRGB and things will about match. IIRC Oculus have exposed it to BP in last couple of plugin releases but you'll likely still need to use the Oculus UE4 version.

viscid aurora
#

@wary coral thank you

#

@candid viper thank you it worked with rec709 , thanks 🙂

wind yacht
#

@modest cliff That'd be awesome! Any input would be great.

modest cliff
#

@wind yacht Could you elaborate a little bit more on what solution you previously used? As far as I'm aware there are two different ways to go about occlusion in 4.26 and depending on your previous solution one or the other would be better suited.

#

I was trying to use the new component at first, but realized that it's dependent on the device supporting it. On the Google AR Core side of things you would need to check which devices support the depth API. But since this decreases the possible target devices drastically I instead used the new occlusion materials directly (as a material on my meshes) instead of said component.

#

You can find them (depending on the platform) in the Plugins folder (make sure you have show engine & plugin content enabled) called "AppleARKit Content" or "ARUtilities Content" respectively

#

For Android I used "MI_ScreenSpacePassthroughCameraExternalTexture" and made sure "bUseExternalTexture" is set to true.

#

Then make sure you properly update said "External Texture" with a setup like this. Where the new "GetARTexture" node did the trick.

📎 unknown.png
#

You would only need the last to nodes to be run in Tick

#

Yeah that's about it. Hope that helps 👍

wind yacht
#

Awesome this is exactly the info I needed.

#

I was originally using the now depreciated passthrough material for arcore

#

I'm wondering, are you getting any slowdown in your AR project(s) with 4.26?

#

My projects (even the base AR template) are receiving huge frame drops

modest cliff
#

I didn't notice that specifically (tested on Samsung Tab S4, Huawei P20 Pro and a Xiaomi Poccophone F1)

wind yacht
#

I'm running on a Galaxy S10

modest cliff
#

Maybe there is a setting somewhere related to mobile graphics which is now different by default (I was building with 4.26 Preview 5 or 6) the last time

#

Hm, I don't see anything too funky

#

What SDK version have you been using?

wind yacht
#

Let me check

#

I am using 29. I'll update to 30 and see if that fixes things

#

Also, for the material you posted, are your nodes running in one single blueprint, level blueprint, or pawn? or is it multiple BPs that are using the texture (which I doubt but wanted to check)?

#

Thx for the help btw

rigid bear
#

I am currently running into an issue where the "vive press trackpad left" and "vive press trackpad right" action event bindings get triggered by pressing anywhere on the trackpad(not just in the designated area). is this a bug with ue 4.25?

modest cliff
#

But it depends on your setup actually. I only have one large mesh which is used for occlusion. But if you assign the same material to several meshes you just need to update that specific material.

#

Which you would actually do thinking about it ^^

#

Ah and I was on SDK 29 as well btw

wind yacht
#

I have multiple BPs that use the same passthrough, so I was thinking I could have only my player pawn update it on tick

modest cliff
#

That should work yes

wind yacht
#

I'm going to run a SDK 30 build and see if it fixes performance. I am going to guess it is something with rendering since I'm getting shading I never originally had on my meshes

modest cliff
#

Yeah that has improved by a lot

#

But would be my initial guess too

wind yacht
#

I don't know what to fix for that though. I have a regular directional light, but should I be using an AR directional light instead?

modest cliff
#

I was using a regular one, but used the AR Sky Light

wind yacht
#

or i mean AR skylight

#

ok, I'll see if that fixes things

#

thx again, this is the most help I've had/found on 4.26 AR information

#

With a worldpsace UMG widget (in a widget component on an actor) - I know about "sending pointer/key" info to the widget using a Widget Interaction component.

Hi guys, small question, in UE when you use VR preview instead of Launch, is it the computer that runs the computation?

#

I'd like to know if I can trust the framerates displayed when using "VR preview", as I want to know the performance on Quest2

#

I suppose that it's the computer who runs the game as there is no building process like when you use "Launch". Do there is a way to limit the performance to imitate the Quest2 if so?

rose current
#

Yes, the computer is doing the calculations

#

@neon geyser I guess you intend to deploy your app as a standalone app to Quest2?

neon geyser
#

No, I'm just playing a bit with the Robo Recall mod kit, but the option to launch is not available, so the only way to play it in VR is the "VR Preview"

#

I'd like to understand a bit more how they reached such performances, but without the Quest2 to make the calculations I cannot really test anything

rose current
#

If you would like to simulate your computer hardware as quests hardware then it is not possible.
You can only profile the VR Preview then in your case.

Howdy all, I was wondering if anyone had a vr charter setup similar to the one below, and how they solved the capsule being able to move and the camera being able to move (someone takes a step in the play environment), and keeping the capsule and camera lined up

📎 unknown.png
neon geyser
steady sparrow
#

Hi ! in a no-gravity environment with an IK full body, how would you suggest I handle the capsule?
I am using VR expension plugin.

I want to be able to move around with the joysticks as well as in real life.

I have set my hmd to floor level but if I don't tick the "centre on hmd" box the capsule does not follow the height I am at when I get up and get out of the capsule. On the other hand, it does follow me when I move around with the joysticks.

Problem is that if the player approaches the ceiling with the sticks and then decides to get up he will be able to put his head through the ceiling as long as the capsule does not block him.

There is a note on "center on hmd" " todo test in multiplayer". So I don't know if I'm allowed to use it online.

should i modify the position of the capsule so that it follows the hmd in height? and if i do that, it will surely be greedy in term of bandwidth, can it do it for a p2p game from 2 to 4 players? Thanks

tired tree
#

@steady sparrow you can use CenterOnHMD if its defaulted to true, its not fully multiplayer compatible in that if you live switch it there can be some roll back.

#

also you can resize the capsule height by hmd position, but that is expensive and i wouldn't do it if you want it to change a lot.

#

specifically on CenterOnHMD, that was added for someone that requested it for a low G game, so you are on the right track

opaque gorge
#

@iron pine @rich canopy

Honestly I really just want to know something involving ai and VR. I swear I've been trying to figure this out for a week and it's bothering me

tired tree
#

something what, you didn't specifically ask

#

is it targeting the HMD location instead of the pawn center?

viscid moat
#

@tired tree I have discovered that resizing the capsule on tick seems to be pretty expensive and cause issues, but I can't find a way around it if you wanted to prevent collision with say a low hanging object that you wanted to duck under. Is there any alternative to resizing the capsule that would allow you to achieve this still?

tired tree
#

@viscid moat not in a network safe way really, generally you would design around that. In singleplayer you coule capsule resize at 10htz or something low and it shouldn't be too expensive. The issue is that you can't scale capsule geometry without changing the cap radius, so it has to pretty much re-create it when you change the size.

viscid moat
tired tree
#

is this on quest

viscid moat
#

No. Index or vive.

tired tree
#

really shouldn't be a computational issue on desktop if you aren't doing it on tick

viscid moat
#

Oh ok. Well then in that case I won't worry too much. I was thinking networking wise would be the issue.

tired tree
#

i replicate capsule height if the option is set

#

its not going to be free, but depending on count should be managable

#

there is room for a more custom solution depending on gameplay, this is just setup for the standard character movement modes to not break them

neon geyser
#

Do there is a way to not make drawcalls for a model who is behind a wall? When I put a lot of skeletal models in my scene, my performances go down rapidly, but even when they are far and behind several walls (Not sure it has something to do with drawcalls tho)

steady sparrow
#

@tired tree Thank you. So for exemple if i want the capsule being a little bit over my head and cover my body to my knees, i have to center on hmd and apply offset on capsule to get desired collision covering ?

tired tree
#

@steady sparrow that should work yeah

steady sparrow
#

It makes me feel confident about my foot ik system as well. It should work properly if the capsule is fixed in relation to the hmd and always lets the same leg length underneath.

#

cool thx a lot

tired tree
#

@steady sparrow moving the capsule with that character doesn't actually move the actor

#

so that wouldn't be true regarding the IK

royal plume
#

is center on hmd a native feature or something specific to the vr expansion plugin

tired tree
#

specific to my plugin

royal plume
#

oh gotcha, I didn't know you made that plugin, that's awesome!

trail shale
#

Trying to make a function where you hold binoculars to your face - so both motion controllers colliding with a collision of the VR pawn trigger it, but it is getting triggered too easily , so I put some collision capsules smaller than the controller (they had a rather large capsule collision) and then set them to a controller only collision channel - On my VR pawn, an overlap event from a capsule collision directly on the head of the player, triggers it ...is this a good way to do this? It SEEMS to work but I've thought I had this done right before, so I'm checking to make sure this is a good/best practice

Guys sorry for dumb question. I tried searching and cant find the solution. I am getting this error and its only when I use the water plugin on Oculus quest 2 packing. Can you point me in the right direction?

#

looks like you need to rebuild your chaos_ascention.target

#

Missing receipt 'C:\Users\justi\OneDrive\Desktop\Unreal Projects\Chaos_Ascension\Binaries\Android\Chaos_Ascension.target'. Check that this target has been built.

#

I used the launcher version and don't have visual studio. How would I rebuild it? Sorry for the noob question. Would I be better off getting the github version and compiling it?

trail shale
#

yeah but you will prob need VS for that

#

gotya ill download VS and github and retry

#

thanks for your advice

#

@neon geyser sorry you are right

#

my bad. I remember that was something similar also for the Quest. Let me check.

#

@neon geyser vr.pixeldensity should work also on the Quest/Quest2 but there are conflicts reported with the FFR settings

neon geyser
#

Oh cool, gonna check that now

#

Does someone have an idea of what happens here? I have 64 pawns in front of me, I run at 72 fps. Then I step back few meters and I start to have huge frame drop. There is nothing else on the map.

📎 received_704040106915249.mp4
#

Is it because my field of view increase so both eyes have to render the 64 pawns?

#

But if I got closer I have 1 million tris, and if move further 300k. So my fps should increase when I go further, so why the inverse is happening?

#

Only draw calls increase

spare yew
#

anyone else getting this error when trying to use scene depth in ARCore? I thought depth reconstruction support was added in 4.26?

question for you all. Is there a way to preview my VR world, but not have to put on my HMD? i.e. simple wasd and mouse control f8!

wicked oak
#

@neon geyser pawns are calculating animation. I think some of the animation calcs are skipped if they are off-view

#

dont trust those counters much. Run unreal insights

#

it will instantly tell you what your bottleneck is

neon geyser
wicked oak
#

with a lot of characters, unreal bottlenecks in animation and game thread

#

graphics is almost never the issue

#

if you are under reasonable drawcall/triangle counts

neon geyser
#

Yes definitely, I'll try to use Insights to see if it helps. But maybe I just reached the limit of the Quest 2, regarding skeletal meshes.

twin zinc
#

Question: if I'm a beginner developer who just wants to share his early tests with friends who have Oculus quests, what's the best way for me to accomplish that? Export and send apks? Side quest? Something on the Oculus store?

#

I thought I remembered reading something about how to upload private tests to the Oculus store, but I'm not coming across it at the moment

#

I could be insane too

sonic lake
#

@twin zinc you can package from UE4. It will generate an install/uninstall set you can send to your friends. They need ADB to complete the install and their Quest needs to be set in development mode.

twin zinc
#

Gotcha. I thought there was a way to keep my friends updated without having to send a new apk though.. Am I just making that up?

#

Like, right now I'm just developing for fun and I'm using a bunch of copyrighted material to make an homage to one of my favorite old NES games, but if it gets far enough in development and it's fun enough that I think I'd like to market it, I could reskin it and put it up for sale... Thing is, I don't know how well all that would read in that PDF that Oculus requires for project submissions

sonic lake
#

@twin zinc it should still be possible to upload to the Oculus Store as alpha/beta and have them test it from there.

twin zinc
#

Do you think I'd still have to submit a pitch presentation to have access to that?

#

I'm just not seeing where I'd upload without going through that whole process

sonic lake
#

It's right there. Not sure where you are looking.

twin zinc
#

When I go to create a new app, I end up at a prompt to upload my pitch presentation

sonic lake
#

@twin zinc true, works for the Rift, not for the Quest.

twin zinc
#

Interesting

sonic lake
#

I guess they changed their policy. Then packaging and sharing or SideQuest is probably your best option.

twin zinc
#

Gotcha

#

As long as I'm not missing something, that's fine

#

I appreciate the help

sonic lake
#

The only problem you may have is if you are using any Oculus online service, then they may not work, but having your friends try out your VR game by uploading it to their own devices should be no issues at all.

twin zinc
#

Oculus online service like if I've implemented multiplayer or something?

rich canopy
#

They have only ever allowed people to put their apps on the store when it’s approved. But that will be changing in 2021 in some ways.

I am having some difficulties with building a project for oculus quest. I have an error log, but I don't really see anything that sticks out, and it tells me to re-run with --info or --debug to get more input. I've been building for quest installation through the "launch" GUI button. Is there another means of doing launch which allows command line inputs? I tried googling the error but didn't find the answers I expected. Attached log just in case.

twin zinc
#

Do you all have a preferred method of seeing a quick preview on screen if you're using a quest?

#

I see that VR Preview is only available on rift?

#

I'd really like to not have to spend all that time "launching" just to try out little changes

lavish flame
#

@twin zinc the only means I've seen is running on link, which is obviously not ideal if you're trying to put the mobile hardware through its paces. I've mostly been doing level design/geometry and gameplay feature testing through this method. Sorry I can't give a better answer.

twin zinc
#

I've got my quest wired in via usb-C, is that "link"? or is that something else? figured that out pretty quick

twin zinc
#

is there a way to play my level, but keep the perspective view I currently see, rather than the camera?

neon geyser
twin zinc
#

@neon geyser would you mind elaborating on that?

neon geyser
#

If I understood correctly you're not able to use the Play in VR option with a Quest right?

twin zinc
#

I'm not able to do "VR Preview" with my quest

#

what I am able to do is either just click "play" using the selected viewport, and miss out on being able to control my pawn with my hmd and controllers

#

or I can "launch" it on my quest, which takes upwards of like 30 seconds

#

I'm sure I could build in some debugging stuff like restarting etc, but to update when I change something is a little bit of a slow process

neon geyser
#

To launch VR preview you need the Oculus app

#

And you need to launch it when you use unreal @twin zinc

twin zinc
#

Is that a PC application? Apologies if this is super basic stuff, I've been trying to research it, but my Google-fu may be lacking

#

Is that what you're talking about?

neon geyser
#

there is a link "Download Software"

twin zinc
#

awesome! so if I run that, and my quest (1) is hooked up with the usb-c cable it came with, then as long as I have it running when I open unreal, I should be able to do a vr preview without that long "launch" process?

maiden willow
#

@twin zinc correct. If you have your Quest 1 or 2 connected via Link to the Oculus desktop app prior to opening your project you should then be able to do VR Preview In Editor.

twin zinc
#

hot damn!

#

awesome ,thanks all

maiden willow
#

Keep in mind though that this will always only show how your PC is performing and not how it will perform on the Quest natively

twin zinc
#

definitely good to keep in mind 👍

#

here's another question. I've been building in 4.24 because that's what a few tutorials said to do. Is it safe to build in 4.25? Looking at this video specifically

at the moment, I'm really only interested in dev for quest 1, since I feel like I can be pretty sure that anything could handle what I throw at it if I optimize it for Q1, and it's what I've got available

That is a great baseline to follow. It honestly all depends on what you want to achieve, but these settings help you for that aim

#

building on slunt's questions, is is possible to run builds directly on quest live from unreal on PC, or is it necessary to do the build process? I can use link, but I was more curious about doing the testing directly on the headset

#

sorry, performance testing on the headset I mean

maiden willow
#

Unfortunately, the only way to achieve this is to either build the APK and transfer it (ADB or SideQuest) or to launch it to the headset. Any previews are utilizing your PC's hardware

bummer. At least my build issue disappeared somehow

But yeah, solid list

vernal spear
#

i've been surprised to not have found an existing collection of unreal engine benchmarks

blissful bear
#

If you factor in different renderers and apis for the benchmarks eg forward or deferred render and ES3.1 or Vulkan you'll provide some useful data. Extend this across UE versions and it'll be very interesting.
You'll have your work cut out! Good luck.

vernal spear
#

luckily i've already been through the pain of building across multiple versions with scripts and all that. for now though, i'll be sticking with UE4.25 and 4.26 with forward and deferred rendering.

twin zinc
#

question for you all. I'm a beginner dev, and I understand that we can't use 4.26 yet for oculus rigs (I've got a quest 1).

A) is that accurate?
B) is the Oculus plugin always a version behind
C) If not, how can I best find out when 4.26 functionality becomes available?

You can, who says cannot?

Quest 2 APK launches to a black screen.... log doesnt say anything wrong.... . Using Oculus 4.25.3..... Any ideas?

Try using Vulkan instead of GL3.1 maybe. I'm still using 4.22 for Quest 2 because of reported problems with 4.25 and 4.26.

#

its weird - I have another project, same engine, same settings, and it launches fine

#

Is Vulkan slower?

Do you have default map set correctly? Vulkan is slower, apparently, not tested myself in anger..

Default map is set.. log indicates it is loaded

I've heard that some UMG widgets can cause problems on Quest... Isn't UE dev just the best fun ever?

whats an obb file?

#

when installing, it unistalls the old, and cant find obb file

#

still says Installation Successful

#

looks like it grants read and write to obb fine though

blissful bear
#

It's the game package for Android, roughly speaking. Ignore the error, its spurious. I get it too.

short laurel
#

kk

#

its gotta be some obscure setting i am missing

#

gonna try the latest oculus integration - the one i am using is from oct

blissful bear
#

Good luck! I'm on the lookout for success stories using 4.26 for Quest 2. I expect we may have to wait until 4.26.1 at least. I have to move away from 4.22 at some point soon. Let us know how you fare!

short laurel
#

yeah i tried 4.26 - got error launching

blissful bear
#

Yeah. It a wee bit of a mess...

short laurel
#

4.26 has Oculus plugin 1.51 and I think Quest 2 requires 1.52 or later?

#

or maybe 1.51 is enough?

#

so confusing

blissful bear
#

Maybe. I use launcher 4.22 and it works spectacularly well for Quest 2 using ES2. They are some oddities that I guess may get fixed by using a later version but from reports I've read I'm in the happier place compared to .25 and .26

short laurel
#

yeah.. that plan does seem better

#

ive got some stuff that requires 4.25

vernal spear
#

is there still a sample of tapppy chicken somewhere?

#

having a bitch of a time building a small apk for oculus quest 2

blissful bear
#

I've got PC projects using 4.25 features too. I wanna have the latest UE but the time isn't right if you need to meet deadlines.

#

@vernal spear UE has a really hard time getting down to really small apk sizes. Unity is better if that is your primary consideration.

vernal spear
#

nope definitely using unreal

#

i'm ok with a big apk, i just need it to actually load on quest 😄

#

seems like if the apk exceeds 240MB or so it won't even launch

blissful bear
#

Make sure 'Package game data inside .apk' is unticked in Platforms - Android - APK Packaging and also tick 'allow large OBB files'
Good luck!

vernal spear
#

will post a list of what i've done...

#

Set up Android platform and add to platforms
SDK version to 23
Enable fullscreen immersion
Start in VR
Add Oculus Quest 2 and remove Daydream
Set the maps both to MotionControllerMap
Only include the one level in package list
Switch to forward rendering
Set up 4x MSAA
Disable Mobile HDR
Create compressed cooked packages
Exclude editor content

#

Doing all this, you get a 200MB APK and 32MB OBB.

blissful bear
#

If you do what I say you should get a 32MB apk and 200MB obb.

vernal spear
#

double checking settings!

#

package game data inside apk is unchecked

#

ticking large obb and repackaging 🙂

blissful bear
#

Ahhh, you are using 4.25 or 4.26?

vernal spear
#

thanks for the help! appreciate it, first time working with android

#

4.26. had same issue on 4.25 so i upgraded

blissful bear
#

I think using OpenGL3.1 on 4.26 causes launch problems (don't quote me though!)
I'm using 4.22 for these reasons as I was just saying to another chap.

#

I think your problems may be related to this rather than the packaging. Possibly?

vernal spear
#

i'll give it a try this afternoon

blissful bear
#

All the best my friend!

vernal spear
#

also asked about it on udn, so we'll see if they have a solution for 4.26

#

Hey guys, I had some spare time recently to edit and upload some video tutorials based on questions often asked in my personal discord channel. So I thought i'd share them both here as it could be helpful as well.

blissful bear
#

Is it using 4.26?

vernal spear
#

perfect, i'll give those a look too!

#

i thought android and stuff would be about the same as for desktop platform. i was wrong 😆

blissful bear
#

Ha, wait until you try iOS!!!!!!!!!

vernal spear
#

oh man did a little demo about 2 years ago where people could customise a tree on an ipad and plant it in a forest running on a big display powered by a pc. show in 2 weeks? no problem, it'll be easy! it was not. 😅

#

there's a certain developer pride and idiocy of saying "it'll be easy!" over and over and over and never quite learning your lesson when it isn't

blissful bear
#

You are right. I've learned to be quite risk averse when developing for mobile platforms. Hence my reluctance to leave 4.22. I hate Apple

dreamy ivy
#

These videos currently use 4.25.4 i believe as i'm currently waiting for 4.26 to be released on the Oculus Git hub since there seams to be a crazy amount of issues with the epic launcher version. These tutorials should still work with 4.26 though.

looks like opengl vs vulkan may make a significant difference, @blissful bear

vernal spear
#

hmm... armv7 with all those settings still results in a 243MB apk with a 47MB obb. what on earth is going on here 😄

short laurel
#

@vernal spear in ue4 you can use the SizeMap to see if any assets are using some unforeseen references. Can also use Reference Viewer to track down offenders

dreamy ivy
short laurel
#

so there is some weirdness with packaging... like I added a material with WPO to test, apk hangs with dots.... deleted that material, repackaged... still hung with dots.... switched to vulkan it worked.... added back it apk hangs again... removed... still hangs

#

nothing in logs

#

just the 3 dots....

#

intermittant -

#

gah

#

[FIXED] So looks like another setting I was missing was ""package game data inside .apk" . not sure why it worked intermittantly without that... but seems to be working consistently again with that checked

vernal spear
#

Trying it in just a bit. Also been running into weird issues on my end trying to reduce it. Maybe the size isn't the problem though...

#

Online links suggest you can get a template project down to like 40MB. Looks like a no can do for Quest! But can't hurt to try some more

mystic edge
#

@trail shale i wanted to do some really simle stuff if i could figure it out

vernal spear
#

have created a new template uproject on github here as a reference for optimal build settings. still working out kinks, but when building for development 88% of the apk for a nearly empty project is libUE4 now.

#

@short laurel did you end up getting a good grasp on what was causing the apk hanging?

#

my development apk is 245MB and shipping apk is 237MB so there's definitely something fucky going on, but i'm beginning to think it's just my machine 😄

short laurel
#

I did! in summary just have to get all the 10 million settings correct... I never got 4.26 working, but was able to deploy to device using Oculus Integration (1.52 and the latest 1.55)

#

Some key things - Use Vulkan, enable "package game data inside .apk", use minimum apk 25

vernal spear
#

what's your apk size?

short laurel
#

lemme check -

#

there is nothing in it

#

120MB

that's the shipping or development build?

ooo here is an interesting window - on the oulus plugin settings there is a "Performance Window Dialog"

good stuff in there yup!

#

i have a feeling the guys on udn will have some ideas too. i always learn some esoteric thing whenever i go there 😄

#

how big is the apk you are cooking?

vernal spear
#

240MB!

#

do you have a lot of levels/assets or is that an empty one?

using all the settings we talked about, not seeing anything significant in diff 😕

which oculus engine are you using

#

lemme see how big my other one is from oct

#

So using the earlier Oculus integration (OVRPLugin 1.52):

#

ARM64 is 153MB

vernal spear
#

armv7

short laurel
#

149MB

#

Do I have to codesign to package for distribution?

vernal spear
#

1.51.0, maybe i need newer ovr

#

yeah - you can grab latest from oculus github

#

the latest one has Phase Sync

which sure is a cool sounding name

vernal spear
#

funny thing is it seems to be my ue4lib is massive- the vast majority of my apk.

short laurel
#

supposedly reduces latency

vernal spear

maybe i set some build flags somewhere a while back

short laurel

its worth getting latest and doing a clean engine build... only downside is it takes a bit

#

the more cores you have the better

trail shale
#

I'm happy with the way this looks - problem is, on the inside, you can't see the shattered part - mainly because the shattered glass is one material (it's transparent) and what you are seeing is the regular, unshattered glass on the OTHER side) ....how best to go about this? (note, the glass material is part of a master material is and is very complicated)

assuming you checked "two sided" on the material and it doesnt work on inside?

if it were two sided then i would lose the blend affect of the two DIFFERENT materials

#

is the shattered glass material a dynamic instance?

trail shale
#

not dynamic but an instance @vernal spear

#

kinda got it but now it's not security glass like where you can't see thorugh it on the outside

#

basically that same opaque shiny black look, I need to i guess make a new material that multiplies those two different materials? how do I want to go about doing this?

translucency is a bit of a rough spot since most of the translucency features depend on deferred rendering as i understand it

i'm 99% sure there's a bug in the packaging process since i can't unzip the 450MB apk file.

hey, i am having a weird issue with widget Interaction.

Anyone have any idea about this

So is there a better way to enable VR than using Stereo On console command in a BeginPlay node of some Actor? Seems like something that I should do in my C++ UGameInstance Init() function or something.

Hey, does anyone know why the live GPU profiler wouldn't show information for mobile/VR (Quest) ? It shows practically nothing for that platform.

#

running stat gpu only shows:

Mobile Scene Render
Slate 3D
Slate UI
Shadow Depths
Prepass

but nothing else is shown

#

it should show Basepass, Postprocessing, Reflection Environment, etc.

Basically I have an open level that opens for sure a valid level with a valid path in project settings. In oculus build it reopens current level instead of selected level. The selected level was previously moved straight to Content folder and it fixed this problem but now it reapeared. Does anyone know how to fix this stupid bug?

what's the general VR headset people use?

viscid moat
#

Unfortunately there are many. I have a vive and an index but a lot of people now have the quest.

#

They are all very similar it’s just the controls that differ slightly and now with mobile headsets like the quest, less performance in some cases.

Get a 64GB Quest 2 and a link cable. You'll be able to dev on your PC and leverage your gpu and cpu to run things over the link cable to the Quest. You can play SteamVR and Oculus store games this way. Advanced: You can also produce an Android build that runs on the Quest native without any cables. This is where it's at imho! Lower performance and recent versions of UE however make this sometimes difficult to build and deploy.
The Quest 2 is an amazing bit of HW for the price, great display and tracking. You have to hold your nose when it FORCES you to login to Facebook however.

Hi, I´m looking for help with placing objects / actors in VR and keeping their simulated position. I´ve tried VR Preview, VR mode and know about the "Keep Simulation Changes" option, but it´s not working in VR (nor preview or VRmode). Does anyone know if it´s possible to script this in Blueprint ? Can anyone help me with this ?

hollow tiger
#

does anyone have any good links for tutorials on how to spawn items from a catalogue, similar to how you can in the steam lounge thing?

inland acorn
vernal spear
#

@hollow tiger should be pretty straightforward, but I don't know of any tutorials. I would set up a widget with a panel and child buttons where each child button broadcasts an event with an asset reference. A catalogue manager actor can be subscribed to that event and calls spawn actor from the asset reference at the desired location. Use a catalogue manager actor in case later on you want an effect like being able to drag and drop the actors or delete all spawned catalogue items or change them as a unit. If you need to do it dynamically this gets a little more complicated with reading an asset registry. I have some old c++ code that is related to the topic of listing and loading assets dynamically if you're using c++

naive fox
#

I'm trying to line up a VR environment with a real world environment that matches. What I am thinking of doing is placing the controllers in two real world locations which correspond to locations in the unreal editor, and then somehow making it align me based on that. How would I do that?

short laurel
#

Has anybody supported a laying down VR experience? Trying to hook into Reset orienting correctly in a recliner

tawdry bough
#

Do you think VR could be good for marketing?

vernal spear
#

@naive fox yes, doable. i'd recommend using a controller and the headset itself. the user starts in a specific location. this location is the origin, player start. then one controller is used to calculate a more accurate forward vector. you're going to run into problems with the forward vector, not with the start location. start location a few centimeters off? who cares. forward vector off by a couple degrees? big oof as you get further away from the origin. end result for me was to put down two stickers. please stand here and place one controller here. one you have the origin and the forward vector, you're good to go.

#

expanding on that a bit, you're not going to try to map these to locations in the world. you're going to use that "stand here" sticker and put it exactly where player start is. then you're going to put the "place controller here" sticker in front of it to establish the forward vector for player start.

#

@tawdry bough what sort of marketing?

tawdry bough

Allowing you to interact with a product maybe?

yo does anyone know the fix for the valve index controllers offset?

#

like when im playing my ue4 game with the Knuckles the hands rotation is like 45 degrees off, its super weird

vernal spear
#

@tawdry bough surprisingly difficult to do. you need to sanitise the headsets between people using them. also, the general public tends to find it extremely challenging to put on virtual reality headsets...

Is there a way to switch between HMD and not modes in a packaged game? Optimally i'd like to just press a button and move the game back to normal windowed/fullscreen play. (game works with/without VR because it's a vehicle game)

DOES ANYONE AT ALL KNOW HOW TO MAKE A NORMAL FUNCTIONING LEVER!?!?

#

SOME KIND OF TUTORIAL OR ANYTHING!?

twin zinc
#

I'm having a hell of a time getting unreal and the oculus software to play nice. Is there a particular order I need to open things/run things in to get smooth performance in unreal while oculus is running?

vernal spear
#

@tawdry bough what's your example of good functioning lever in vr?

abstract forum
#

Try that

#

If Unreal opens Oculus you should be ok tho.

#

and make sure your device is turned on

tawdry bough
vernal spear
#

so if i let go of the lever halfway between an off and on it should stay there?

tawdry bough
#

Well it doesn’t have to

#

Just behave how a lever would work irl

#

My current problem with the lever I made from scratch is when the other hand overlaps it, for some reason it switches to that hand as the one controlling it

#

What also sucks is that I’m having problems with turning it on a single axis, for so,e reason it only works if I’m allow free rotation

#

I’ll show you the code for it tomorrow if it helps

vernal spear
#

yeah upload a codeshare or something.

#

for the other hand, most implementations i know keep a pointer to the hand currently grabbing the lever. if another hand attempts to grab it, the pointer is checked and allows a grab only if null

#

that pointer is also used to get the location of the center of the hand and then sets the rotation of the base of the level component.

#

i've seen some implementations that try to use the physics system, but there are a lot of edge cases for that. if you just want a lever that behaves nicely when grabbed, create a base and a lever. set the rotation of the lever using the vector between the lever base and the hand, setting only the rotation in one direction. set "on" and "off" when thresholds are met on the rotator.

#

also people have a tendency to jerk their hands just a little bit when they're grabbing or letting go with the controllers. you may find the lever feels more accurate if you use the hand position from 50ms or so ago (4 or 5 frames) when letting go.

#

that or maybe it's that people don't let go before they start moving their hand away... hard to say. doesn't seem to be as much of an issue with more experienced vr users.

hushed socket
#

does anyone know offhand why when testing my project in the editor VR is disabled every other time i use the "play in vr button", like i need to close and reopen it twice for it to load on the headset

short laurel
#

@hushed socket When you launch UE4 editor, it should detect if VR HMD connected and enable button? Does button get disabeld after you play?

hushed socket
#

It detects fine. What happens is you press preview once, it works fine, press it again, it's non-VR, press it again, works fine, again, non-vr

#

i found a few answerhub questions of people asking the same thing but there are no solutions attached to them

#

Basically means when iterating on VR i have to open a preview and close it then open another one every time i want to preview, bit of a pain

short laurel
#

hmmm - so using the dropdown arrow next to the Play button and selecting VR Preview is periodically disabled or does it just run regular PIE?

tired tree
#

@tawdry bough if you know how to read c++ my plugins github has a lever component that handles any axis and even multi axis movements with different release settings that you can reference.

#

I also have a bp example but it uses my gripping system so some of it is hard to translate to the std epic template

hushed socket

#

the answer to my apk size problems was indeed go back to 4.25. after that, download and use the oculusvr version from github to reduce it even just a little further. looks like there's a bug with 4.26.

Hello guys. Is possible publish a vr game at the epic store? I don't see the vr category.

tropic kestrel
#

(most likely steam vr)

#

either that or people can't use their knuckles controllers

#

You can do keyboard / gamepad + HMD easily, OpenXR lets you do that

#

but the platform specific hardware like controllers makes it a pain

vernal spear
#

Anybody find that on the OculusVR source build if you wipe all the intermediate data for a project and package,everything works fine, but if you make a small change (like deleting an object from a scene) and repackage the app doesn't boot?

#

@paper radish when launching your title on Epic Games, users will need to choose a launch option. the epic games store makes this reasonably easy to do.

About OPTIMIZATION for VR.. drawcalls shown in editor is it aswell for vr or di need to double them in head because of STEREO?

vernal spear
#

ehhh it gets weird. it's usually not quite going to be double

#

but if you're looking for a rule of thumb, i don't think that's going to be a problematic estimate for the most part

twin heart
#

Well i have in my lvls mostly 800 average where it bumps up sometimes to 1300 drawcalls.. i target a pc vr online game. How deeply i am in trouble there?@vernal spear?

twin heart
#

Ah yes read it now with both eyes , well its little confusing about optimisation.

#

Thats the Situation

vernal spear
#

you might have issues with lower end machines there due to the large texture memory

#

optimisation is a touchy feely subject. at least, that's how i approach it. a lot of people get started trying to optimise their game and go "this is too many draw calls, this texture memory is too high, i need to remove translucency drawing, etc. etc."

twin heart
#

Absolutely but its at least post optimisation... but yeah when players gonna move i don’t know what happens

vernal spear
#

i think you're gonna be ok as long as players have reasonably strong gpus. have a pretty good gpu is a general requirements of vr, so you're probably ok 😄

twin heart
#

Yes i am a noob still so its very confusing at all .

paper radish
twin heart
#

Yes that’s true sounds nice maybe you find the time to test it one day? It at least womt look bad😄

precisely

twin heart
#

I can’t feel the lowe end gpus... i develope on a 3080 probably not so clever... the gpu can run run half of tokyo while having seizures

vernal spear
#

i gotta admit though i've never developed for a marketplace. i've always known exactly the hardware on which my application was going to run. trying to guess how your appliction is going to run on someone else's computer or a computer with random specs is an impossible task.

#

yeah, trying to guess those low end gpu's is not a great time 😄

twin heart
#

Yes indeed, probably i gotta find alphatester wiron stomachd

#

With

vernal spear
#

a nice thing about unreal is downgrading assets as you go is pretty easy. used to be you had to figure out as early as possible what the machine could handle because your model was somewhat set in stone. i approach optimisation as a lastish step now after some sanity tests.

#

having said all that, your scene looks nice behind all those numbers!

twin heart
#

Yes i got you , well i keep trying to get some extra pounds out of it...

#

Thanks commander

vernal spear
#

as a bit of an aside if you were rendering something relatively simple i wonder how many raw draw calls you could make before it really does become problematic... 5000? 8000?

Enable remote port forwarding to link your target mobile port to a PC port: adb forward tcp:$port tcp:$port
Set your device to Developer Mode, as described in Device Setup - Oculus Quest.
Launch the application you wish to debug.
Start gdbserver on the mobile device with the following Unreal console command: gdbserver $port where $port is your port number. You application should freeze, and will now be ready for debugging.
Launch the ndk-gdb client from the command line on your computer with the command gdb.exe. When it launches, type target remote :$port in the GDB command line to attach to your mobile device.```

@lofty oar You can use a single project - but chaning certain things is annoying - eg if Desktop is Deferred Rendering and VR is Forward Rendering then everytime you switch it has to recompile all shaders.... I ended up using seperate projects and migrating assets between the two.

So from trying a couple times I have found that splash screens can be a little tricky. I’m using oculus rift s and from the docs oculus has to be handled differently that other sets. Am I right on that? Different libraries and you need to check what system/set is being used?

More for VR imo. There were two bugs in 4.25 for niagara particles and landscape glitches that were driving me mad that got fixed in 4.26.

Yeah - deleting the intermediate folder did the trick. I missed this step in the video suggested by @short laurel ... I did that and I also removed the cache and daemon folders from the .gradle folder.
I can now see the device and deploy to it.
Step 1 down.
The level runs for all of about 5 second before crashing and it seems that the Quest 2 thinks I'm expecting a resolution of 90 x 50 for some god-forsaken reason. This causes the software to try and fix it... and then it crashes.
Now that I can connect the HMD, I guess I need to know how to build a level for VR.

Is there any way to use 4.26 GPU lightmass with the forward renderer? I've enabled raytracing and set the default RHI to DX12, but I get this message. I have a feeling it's because I'm using forward rendering, but not sure

# maiden willow Normally the shaders are compiled once when opening the project (or being added ...

Hum... it could be that I've been making critical changes as I chase trying to get this scene to work, so it appears that it's recompiling for no reason.
Also, I'm using a default VR project, so there's a lot of useless garf and felgercarb in the project, and even tho' I'm only deploying the one level to headset, it seems to be recompiling the entire project.
I'll get this under my skin as I use Unreal more.

I'm getting a crash on launch with 4.26 as well (along with several others) . There's a forum thread on it, but no solid solution as far as I can tell. I'd give 4.25 a shot to see if 4.26 is the problem

Might not be the issue but I had an issue where I somehow set some of my project folders, like intermediate, to be version controlled in Perforce, so some shaders would compile but not be able to be written to whatever file they normally did. I could test this, literally open unreal, wait for them to compile. Then I'd cleanly exit Unreal. Wait for it to cleanly empty memory (you can task manager and see that just because the window is gone, Unreal is still in memory unloading, can even take several minutes to unload too) - Then I would start Unreal up again and the same shaders recompiled. Went away as soon as I removed those folders from Version control and restore write privileges to them

#

Also AFAIK Unreal also stores shader compilations in Users/LocalData,etc or whatever it is called

most of those issues keep being pushed away for the next release, never getting fixed 😦

I need help with something

#

I have a game that’s in vr that I want to play but whenever it opens it crashes

#

It says Access Violation and repeats the win64 shipping exe file then talks about something else

#

The game was built on nividia cards but amd is not working

trail shale
#

Surely this problem has occured for every VR dev here, no point in reinventing the wheel - I need a debug camera, just to see what is happening in the world, and I'm not putting on my headset everytime, most of the time, it's just hanging on a hook

I have a debug camera that moves the VR pawn to the location of the debut actor and I'm trying to basically frame up the same view as the debug camera -

#

I'm getting there and I can tweak the settings but I'd like to be able to adjust for the position of the VR headset and have it just recenter there

#

@tired tree basically I'm backwards from where I should be

#

Clearly there is a relationship, an offset, I need to consider in this

#

The fact the headset is pointing DOWN, I need to put that in there, so the idea was to adjust the pitch, but I'd love to hear what others have done for this

tired tree
#

this is just for when the headset is off?

#

why not just turn off the camera tracking the hmd or run out of vr mode

trail shale
#

nope, headset is still on

#

togglign VR seems to lead to other issues

#

turning off tracking would work but I don't really need to, it's not moving

#

and I'd still have to figure out the difference in orientation

trail shale
tired tree
#

ah well you set the actor rotation to account for the HMDs relative rotation

trail shale
#

it is the yaw that i'm trying to figure out, I can hardcode it and I guess that will work for debugging purpose

tired tree
#

IE: target rotation - inverse of relative camera location, or even if you want to use only ZY you could use the LookAtRotation from camera forward vector to the forward vector of the target orientation

#

full camera yaw needs to be normalized if you only want yaw, otherwise head tilt is going to effect it

trail shale
#

This seems to work but I think I figured out why it wasn't matching

marsh ether
#

Just a weird Q re: placement of the MotionControllerSpawn (everytime I see that name I can only thing of shooting multi-pass on models...)
Do you set the spawns transform to a height of 0 relative to the ground or, say, 185cm? Is height adjusted? Or set?
Also, when I'm using the default values (add pawn, set "Auto Possess Player" to 0) the entire scene seems ...
... too small.
I have a floor made of 90x180 cm tiles and just looking at them they seem almost half the size I'd expect them to feel, and the room feels about half size, or 3/4's size as well.
Is this a FoV issue?
I know when creating a lot of game styles, perceptive scene design is key and many buildings are ridiculously oversized for the characters (WoW, etc.)...
... I would have thought this not true with VR, however.

trail shale
#

That makes sense, if my headset is facing down, the forward vector is going to be -1

tired tree
#

you don't really want to hardcode an offset when you can make it generic

#

for when the headset is somewhere else

trail shale
#

if you can tell me a simple way to set the rotation of it to match the debug camera, regardless of it it's orientation, I'd be all ears

marsh ether
#

I don't know BP or CPP, but in C# I'd just say myCameraTransform == debugCamera.transform;

#

Can't you just brute force it every fame?

#

That shouldn't have any impact.

#

Do you have a valid reference to the debugCamera? You should (and I know I'm using Unity terms here) grab the value of its transform.

#

Then just assign it every frame to the camera you need.

No, but someone send me a slinky spline thingie and I'll do that, just want to put it on stop of a million stairs like this

My instincts tell me if you wanted a slinky, make a spline mesh of a ring, (flat, cut in half and connected opposite ends with slight Z offset) then move and rotate down

Back to basics here, trying to take your advice - why does it keep the same orientation of the my previous VR pawn? @tired tree

Guys this is baffling me, how can I not setup a simple debug camera, I've been at thisfor 90 minutes

#

the view always comes in slanted

#

I've been trying to be a VR dev for 3 years but maybe I'm just a dumb Firefighter - Why does this not work?

marsh ether
#

@trail shale Why do you need a custom debug camera? I'm not following your case very closely... can you just use the scene view camera?

trail shale
#

what?

#

How?

marsh ether
#

I'm confused by your use case... What are you debugging?

trail shale
#

I don't want to put the headset on everytime just to check on if a light function or an static mesh is placed correctly

#

bad examples I guess

#

but i keep the HMD on a hook and it is pointing down

viscid moat
#

I think he's trying to still use VR simulation mode in editor while having the headset on his desk but not be looking straight down.

trail shale
#

yes

viscid moat
#

I myself have modified my code to be able to run in non vr mode so that the camera operates with a mouse

trail shale
#

this is ridiculously UNintuitive - I have to remind myself to not take this personal because if I don't ,it's like someone is punishing me for not knowing obscure things

#

WHY does this not work perfectly? What key concept am I missing?

📎 unknown.png
#

roll, yaw, I don't care what the headset is doing, if you are locking it to an event tick

clever iron
#

I found it easier to just implement UE4s first person actor in my VR project and use that for testing when I don't want to put on a headset

trail shale
#

but WHY did you find it easier?

#

Why doesn't this work, I'm going to throw my headset out the goddamn window

clever iron
#

because I can choose between first person keyboard movement or VR headset test before I run it everytime

viscid moat
#

I've never tried to do what you're doing but I would assume that since the camera is affected by the rotation of the HMD that you would want to simply modify the rotation by subtracting the HMD rotation.

trail shale
#

You missed my question - I know practically why you did it, but why should you have HAD TO?

viscid moat
#

No matter where the HMD rotates, it will subtract that back to be a normal straight forward rotation

#

Then you can apply the location and rotation of the debug camera? Maybe?

trail shale
#

But the spot I would measure that from is the place I change it

clever iron
#

It's just the first method I tried, it did a good enough job of answering the burning VR question on how to reduce product test time due to headset utilization

trail shale
#

would you send my your BP of your first person character and show me your code so I can just murder this time vampire and move on

viscid moat
#

Have you tried disabling the HMD?

#

UHeadMountedDisplayFunctionLibrary::EnableHMD(false);

#

Could disable it for a time and then put the camera how you want it

#

Then reenable when you want to go back to using it

#

None of this is tested I'm just riffing.

clever iron
#

you just include the first person starter content in your project, then edit your gamemode bp to include a selector between spawning each

Actually Xero's suggestion is really the way it's done, just pick between VR test and non-vr test, and setup a movement pawn for WASD

trail shale
viscid moat
#

Not sure what you mean? That appears to be disabling it and says success = true

Ugh, thank you you are correct

I don't remember the exact steps, pretty sure you can find them if you google enabling starter content in ue4 in an existing project or something. I may have also started a fp project and just migrated it over.

#

christ jesus my pawn somehow manages to crash the editor, it happened again

#

that print string fires off and changes, so I have input

#

but when I move a little bit, the entire editor crashes

#

it's the stupid spectator screen now

#

I've possess the first person character now but it is still zoomed in like it's in VR? i've set enabled HMD to false and stereoinstance to 0 as a console command. @tired tree can you please just show me how you possess a pawn on your end?

tired tree
#

what do you mean? I just possess it

trail shale
#

like this?

tired tree
#

when not in VR mode it just uses a normal camera in a child class of the VR character

It's still using the VR preview so I'm trying to see if I can just undo whatever that vr preview does

So, following this video:

#

And with just a MotionControlPawn, and a NavMesh, I'm trying to use teleport.

I get the contact point, but it won't "deploy" - it stays just under the hand.

Any hints?

I'd take a screenshot, but I've not figured out how, yet.

If you are on Windows, you can do the following hotkey: Windows button + Shift + s - then drag your mouse like a cropping tool

If you are in the Play In Editor (VR Preview) you can do: Windows button + g to bring up the game recording screen

Man, Pimax 8kx + 2080ti has been disappointing performance-wise. 35ms in a small statically lit scene with forward shading. Any tips 'n tricks? I can get to consistent 75fps with a pixel density of 0.5.

hmmm.... seems like removing a planar reflection brings it down to 17 ms average.

trail shale
#

@tired tree what were the specific performance concerns from 4.26 you mentioned yesterday?

rustic cargo
gusty cedar
#

How do you get the velocity of a VRPawn?

#

I tried Get velocity and it's 0,0,0. So i tried getting the camera and getting the component Velocity and that was also 0,0,0 even though I'm moving around.

trail shale
obtuse spruce
#

@gusty cedar GetVelocity returns <0,0,0> by default unless the actor's root simulates physics or the actor has a MovementComponent
If you don't want to set up either of those things, you could brute-force it by adding a script to your pawn that calculates its instantaneous velocity on Tick (change in position / delta time)

gusty cedar
#

That's on tick. I'm trying to make mechanic where you are climbing, and if you pull yourself and let go of what you are holding, it will persevere your momentum so that you can "jump" and try to catch onto another grabbable climbing actor

#

So im trying to capture the velocity when I let go of the block, and combine that with my falling force so that the player can fling himself forward in a parabola

#

like this

trail shale
# gusty cedar This is the whole thing:

It's good to learn this but you might have an easier time downloading a project where this is already done and modifying it for your purposes - @tired tree has a VR Expansion project that is free and they've solved a lot of these problems, you can open his example project and trying the climbing and tweak it how you need it

trail shale
#

You don't need the to measure the camera's velocity for this, you should just actually drop the entire VR pawn down, and the camera will behave accordingly

#

At the risk of being redundant, you need to be extremely careful with movement in a VR pawn - you'll get rid of player base if done haphazardly

gusty cedar
#

yea that's what I do, but when I do get velocity of the vrpawn it's 0,0,0 like you were saying. So I move the VR Pawn itself, but I use the camera for getting the velocity.

trail shale
#

You need to get a reference to the motion controllers themselves

#

and get their velocity

gusty cedar
#

okay so I did that, do I get both and add them together?

trail shale
#

I'd ask #blueprint - once you are talking velocities and inertia, that's non-VR and just pure vector maths

gusty cedar
#

okay that's true

trail shale
#

That event is the time you actually use Event tick, although up there you can see I use .1 but I'm using it just to check if they have set the controllers down...play with it and tweak the numbers, you probably don't need to check it as much/fast as you might think

gusty cedar
#

@trail shale okay so if i did the velocity for the motion controllers. How would i inverse it? Beacuse when you are moving your arms to the left you should move to the right

#

is it as simple as * -1

trail shale
gusty cedar
#

Yea I just feel like it's basic to someone who is comfortable with vector math, which I want to be. I want to know how it works. Not go looking for a plugin everytime the vector math equivalent of 2+2 shows up

Hi hi, I am new to Oculus Quest development, but I am having a specific problem.

I am using the 4.25.3 version of the alpha branch from Oculus and a plugin called Quest Hands to get access to the hand tracking in blueprints. (Build settings: arm64/ES3.1/Vulkan)

The issue: Whenever I go inside passthrough mode and back into my application, my hands lag for a random amount of time and fix themselves after a while (can take up to 2 minutes.) The actual headset hand tracking works completely fine it only occurs to the hand components inside UE4.

Just discovered focus aware does get triggered, might somebody know a way to force update an component?

#

Where can i find the save files on Oculus quest?
If its a shipping build, i cant find it anywhere, if its a dev build, the save files can be found in the game folder.

Is there some magic trick to widgets in VR? I added a widget component to my character, set its location to be in front of it and bind a progress bar to it. Works fine in flat screen but in vr the widget is inside my character and the progress bar is empty. The code is in BeginPlay

flat screen

marsh ether

I can't see why the navmesh is not allowing the ability to exit the building from the large spaces - and this affects the teleport function in the default VR Pawn.

If you can help me know where to look for an answer, that would be great.

@gritty ledge Assuming this is over SteamVR, add _Y and _X to the end of your action names

they require that naming convention to work around auto generation issues they have

Assuming you men this, it does not work. Did I understand that correctly?

you'll need to regenerate the manifest and bindings after changing that

gritty ledge
tired tree
#

@gritty ledge in project settings under steam input (or stemavr i forget the category and I can't pull up the editor right now) there are "Regenerate manifest" and "Regenerate bindings", hit them in that order, there is also an option to have it show on the toolbar at the main top of the editor, which normally isn't that useful.

#

also the auto bindings creation is flawed and will generate bindings that aren't exactly like you like, that is where loading the steamvr overlay comes in to re-map to exactly what you want.

@umbral flare Projected the widget onto a stereo component like in the video, its still attached to my head

I want it to appear on top of my head

smth like the rpg/mmo hp bars

umbral flare
#

If you create the 3D widget as he does at 3:50. You can then attach that blueprint that holds the widget as child actor to your VRpawn and place it above your head. This should be with 3D worldspace and move with your character. The stereo part is if you want anti a on the widget

tawny halo
#

hmm

#

will try that

#

thanks

wheat holly
#

Hi! Maybe that I'm just being silly, but is there no way to give a motion controller component collision? Everything I do seems to just go through collisions. I read about someone hiding the original controller and making a different actor follow it's position while checking for collision, while that seems easy enough is there no out of the box option for this?

tawny halo
#

@umbral flare Works like a charm, thanks a lot

tired tree
#

@wheat holly you wouldn't want the actual controller to "collide" anyway, its the reference state of the real world hand and the real world hand doesn't get blocked by things, generally sweeping another object to match or physically constraining something to it is the solution

tawny halo
#

@umbral flare Actually I was wrong 😦 it works if the widget is set to be in world space, in screen space the same thing happens

umbral flare
#

Well it needs to be set to world space because the widget is within the world right? It's attached to the actor holding the widget component.

tired tree
#

the stereo layer itself can be head locked if you dont want to interact with it

tawny halo
#

Is it possible to make it visible from any angle?

tired tree
#

@tawny halo stereo layers don't have back faces, they are a plane, you would have to rotate / flip it or use two

umbral flare
#

Or don't use a stereo layer but then it will not have anti a

tawny halo
#

I'm not using a stereo layer rn

umbral flare
#

so the edge will look pixelly

tawny halo

I guess i could rotate the widget at tick according to find look at rotation to player 0

umbral flare

Ah I see you can let the widget face the camera

tawny halo
#

but I'm just wondering if there is a simpler way

tired tree

stereo layers don't have AA

they just are rendered directly to the display on the api side

as for widget components, you can super scale their buffer and they shrink down better
