How can I offset the view of a Vive hmd? Or just not have the camera follow the HMD?
sturdy canyon
Lol
sturdy coral
@violet musk explain a bit more of what you are wanting, there is a way but it is almost never what you really want
and I don't think it will really hold it steady with always-on-reprojection now being the default everywhere
tired tree
he might just be wanting third person view of a pawn and not understanding how that would work
violet musk
@sturdy coral @tired tree
I have a Optitrack system that is using eSync2 to combine it with Vive.
We're using a modified version of Yuri's Vive Mocap Kit to capture a person with Optitrack rigid bodies. We currently have an odd problem (and not much time ofc) with an offset between the two coordinate systems being fed into UE4 (Vive and Optitrack). The HMD is quite offset behind the characters head at the moment (tho it's rather being Optitrack being offset) and we're trying to offset the HMD by a bit.
It's a closed system, so reprojection could be turned off.
tired tree
would use advanced steam settings to offset coords
sturdy coral
yeah that's what I use to do knuckles + WMR and bring their coordinate frames into alignment
@violet musk for your original question, on the ue4 side, look in camera manager or the camera (can't remember which) for bLockToHMD
looks like it is camera component
tired tree
you can offset it by manually using the same logic that the Re-Zeroing uses
been meaning to go in and expand on that section...since its not even reversible currently, or customizable
but times limit = Advanced steamvr settings
sturdy coral
interesting
tired tree
ug, i hope not
sturdy coral
it looks pretty similar but only one plane of focus
tired tree
that would be very disappointing
sturdy coral
but the hand tracking looks a lot better than anything magic leap has shown
I wonder if WMR controllers will work with hololens 2 too, did they show only hand stuff or also controller?
violet musk
The Lock to HMD option is toggled on by default and didn't affect my camera when I turned it off... tho it was pretty hectic earlier. So maybe I overlooked something :/
sturdy coral
@violet musk are you already moving the camera component through another means?
violet musk
I don't think so, no.
Unfortunately don't have access to the project right now.
And no Internet where I have to work on it 😂
Great ...
sturdy coral
someone's doing military contracting 😃
violet musk
No, but it does feel like it :9
wicked oak
he said the hand tracking was bugged as fuck when he tried it
couse the software still is not very ready
violet musk
Advanced SteamVR settings is a third party plugin? Or in UE4?
sturdy coral
third party thing
wicked oak
and btw, i have tried the magic leap myself. Its a damn good AR headset
it beats the fuck out of the hololens 1
tired tree
@violet musk if you literally just want to align them and don't actually care if the tracking is actually aligned
sturdy coral
can't remember which
tired tree
just move the scene component that the camera / controllers are attached too
sturdy coral
I've been using pimax instead of WMR for a while now so haven't set it up recently
tired tree
but if you mean that yuriks plugin is sampling the wrong position, then yea
violet musk
The rigid body actor of Optitrack is having an offset is the thing
sturdy coral
yeah openvr input emulator is what I use to tweak alignments
violet musk
The difference between the center of the setup of the Vive and the one of Optitrack
I can get those pretty closely setup in a range of like 10cm~, but it's ofc terrible for VR lol.
sturdy coral
you need to calibrate spaces with points that are far away from each other
I don't know his plugin, but if you do just a few nearby points the whole thing can be off by small amounts of rotation which compounds as you get farther from center of rotation of the tracking space
tired tree
his plugin just samples the HMD module
violet musk
The rigid bodies are driving his (Yuris) IK, but it's not the problem. Shouldnt have mentioned it :9
The Optitrack UE4 plugin provides rigid body components that get driven by the Motive software. Those are offset
tired tree
curious why you are trying to merge the two, doesn't optitrack offer HMD services? its listed on their page? Or did you not purchase their hardware
violet musk
We started doing the prototype with Vive trackers
sturdy coral
what I do for aligning kinect is just let you grab it virtually with controller and move it around, and with other controller for rotating it
and I do some kind of quaternion thing to make the rotations only rotate at a fraction of your hand rotation
so you can get pretty fine-grained
violet musk
And we're about to merge the systems. So yeah, tracking the HMD with markers as well is possible. But because of some interactivity (beside of the HMD) we synched it with Vive.
tired tree
if you want this really good the best "actually build" method I would assume would be vive trackers with visual markers on them
then you offset optitracks "world" until the align
violet musk
But yes, we did buy it
tired tree
could automate it that way then
violet musk
Oh, yeah
Well, to be frank that's pretty much what we're doing. Just manually in Simulate lol
I guess that would be a way
@quaternion: Yeah... I have such a painful history with rotations.
spice mural
Anyone struggled with the ue4 VR mirror mode? 😂
sturdy coral
yeah if you can rigidly attach two things tracked in both systems it is supposed to be very easy to get a near perfect rotational alignment with some kind of math
and then just need small positional alignment based on how they were attached
@spice mural which engine version?
it used to have a lot of problems and would parse one of the commands wrong and leave vive mirror permanently blacked out
spice mural
its for the Rift, version 4.21
I tried the HMD mirror commands but they dont really do anything
the standard mirror doesnt reflect widgets nor both eyes
violet musk
Thanks for the answers, will try some more things tomorrow then :)
tired tree
no mirror setting will render screen space widgets....
tired tree
you can manually draw them on
spice mural
ill play with that and see
tired tree
or do a ton of work to get the detection working correctly / use seperate viewports
its been a comment in the new mirror settings since they came out to add a setting with a seperate viewport for the monitor from the HMD
but nothing has moved on that end
sturdy coral
you can use openvr GetMirrorTextureD3D11 to get the mirror texture after compositing which will have screenspace stuff
and compositor overlays though, like steamvr menu
@spice mural not sure if oculus sdk has something similar
tired tree
he is talking UMG
sturdy coral
and beyond that is unreal's limited opaque wrapper of the oculus sdk exposes it..
tired tree
like a spectator menu
sturdy coral
ah "the standard mirror doesnt reflect widgets nor both eyes" and where you mentioned screenspace widgets
I thought you meant widgets drawn to HMD viewport
tired tree
well default widgets don't do that :p
spice mural
Using the Occulus mirror app
tired tree
were you just talking about the Cropping then?
spice mural
"start oculusmirror --RectilinearBothEyes"
No i was talking about the widgets not displaying
this is what the ue4 mirror shows me
tired tree
that is cropping
sturdy coral
are you sure they weren't just cropped?
you can change cropping mode
I don't know if through command line
sturdy coral
yeah it is cropping to the center
sturdy coral
I think it is vr.MirrorMode now
sturdy coral
alias for vr.SpectatorScreenMode
tired tree
SingleEyeLetterboxed UMETA(DisplayName = "SingleEyeLetterboxed"),

Has oculus said anything about the rift S launch window? Like roughly what quarter?
sturdy canyon
I have heard absolutely nothing about timeline
But I suspect they won't release it until Q4 at the earliest so it doesn't conflict with Quest
sturdy coral
I wonder how cheap they will be able to go
mighty carbon
supposedly outlets ran out of physical stock and aren't restocking Rift CV1
probably an indication that Rift S is coming soon
sturdy coral
That's interesting, I didn't know they would discontinue rift at the same time
sturdy coral
yeah
I'd like that + battery and processing on a hip pack to keep it as light as possible
though that makes it a little harder to take on and off
mighty carbon
I mean, you still can buy Rift online, just not in the brick and mortar store
violet musk
Fighting with that offset Optitrack problem from yesterday. Currently much further and tracking mostly with Rigid Bodies.
The problem right now is that we have this IK actor with a camera. Now unreal always uses the Vive tracking for this camera instead of the Rigid body.
The only way I got it working was by making the Rigid body of the camera the pawn root and having the camera as a child.
But then everything else is a child, the IK etc, is a child of that Rigid body moving around
spice mural
UI in VR, do you expect it to follow the head movement or not ?
I imagine following the head movement feels more natural due to the nature of UI. Only way it would show in "real life" was if you had a glass with a display infront of you, like a helmet or google glass or whatever...
guess it also depends abit on the game ..
maybe to generic question

I'm needing help with errors in the motion controller pawn but I have no idea how to fix them

on Gear VR I used to use bluetooth keyboard to bring console down and use "stat startfile" for profiling.. However, I can't do that on Go 😦 I finally managed to hook up bluetooth keyboard to my Go and it seems to be working in the game (at least Esc works), but console doesn't want to come out when pressing ~/` :/
@sturdy canyon have you ever had issue like that in your project ?
sly elk
@spice mural I personally don't like ui that follows the head
sly elk

spice mural

it would be pretty annoying having to actually look down there

Why not anchor it relative to the pawn so you can look down to see it
spice mural

sturdy canyon
I didn't know that startfile and stopfile worked outside the editor actually
@mighty carbon you can just bind them to buttons in your game
mighty carbon
there are only so many buttons on Go's controller 😂 but yes, sounds like a plan.. thanks
wicked oak
@sturdy canyon they do, if its a Development build
in Release you cant use them whatsoever
ive used them on ps4 to good effect
but oh GOD do they nuke performance
btw yall, did you see that Live++ thing Sion talked about?
it works
in PUBG
we got the trial working in about 10 minutes
mighty carbon
Live++ doesn't work for XBO and I am not sure if it works for PS4.. For PC it seems like a cool thing
(at least based on the info on their website)
wicked oak
it works even on the absolute clusterfuck that its the pubg codebase
where we have hot reload disabled becouse it broke enterely
sturdy canyon
I stopped hot reloading years ago. I just don't trust it
Creates more problems than it solves. But I've heard cool things about live++, yeah
wicked oak
this thing only seems to work on function changes, no struct changes
but still
already a massive improvement
mighty carbon
alright, Oculus is going to really curate Quest project
like, a step above Rift/Go in quality control
I am kinda happy about it, but then also concerned
although it's good thing overall IMO

I have a pair of AR questions for anyone with the know-how. AR Core specifically. Using the ARCore Engine from source (4.20.3)
First question: Is there a way to clear the Tracked Images? We need to have a single AR experience running, but also to be able to run different ones when different images are discovered, in no particular order. Currently, we spawn the experience when the AR image is detected (via GetAllTrackedImages) but we can't tell the system to forget that image for whatever reason. I'm currently trawling through the engine code for the ARBlueprintLibrary but its a rabbit hole.
Secondly; has anyone overcome the "Impossible to build augmented image database" build error? I'm well into my googling currently but so far I'm seeing people having the same issue with no solution as recently as January.
digital musk
I've got a physics component as part of a larger actor.
During runtime - when I set the larger actor from visible to not visible (With propagate to children ticked), this component stays visible but stops moving with the bigger component and stops simulating physics....when I set the larger actor to visible again this component stays visible and once again moves with larger actor and simulates physics correctly.
Any idea what's going on here?
flat shoal
@digital musk using AttachToComponent? with weld simulated bodies?
digital musk
This entire actor is a child actor in my VRcharacter....this scrollwheel mesh doesn't go invisible when I set visibility to false in my VRcharacter...it stays vivisble but stops moving with my character
This works...but doesn't make sense that this is needed

Anyone here have experience with playing 4kx4k video on the Go? Oculus recommends HEVC at 20 Mb/s, but Unreal refuses to open that as a MediaPlayer
It says to check the output log for the reason why, but the logs remains empty, so there's not much to go on
I tried splitting the video into 2 times 4096x2048 so it fits inside H.264 rather than H.265, but it also won't load that

@digital lintel If you want to clear the tracked images, try clearing AR Session, in this way you can reset the image trackers objects.

Does anyone know what it is specifically about a project that makes it try to grab SteamVR's attention? I have an issue where I'm trying to get an asymmetrical VR/PC co-op game to work in packaged form (works fine in editor.) SteamVR/Vive will not let me run two instances of the same package on one machine-- only way it works is if the headset is unplugged. If I can't find a fix for that, I was thinking maybe I could repackage the game with different builds for VR and PC, since I can run my VR package and an unrelated non-VR package together just fine. What would I have to change in the PC build to get SteamVR to ignore it?
Already tried disabling the SteamVR plugin from the Plugins panel.

how do i make something like this? can someone give me tips or any tutorial videos? https://www.youtube.com/watch?v=lHzCmfuJYa4&list=PL9CdB98OxmWkxpnH81AuXguDDXk5Wlb_C

@smoky comet Easy way. Get a plane with a cutout in your fave dcc, and adjust it's scale based on the character's speed. There's a way to do it via material, but that way has changed since 4.19
smoky comet
how do i know the coordinates for my right and left eye?
or is it just one plane with a hole attached to my camera?
sturdy coral
just one plane, otherwise you need really small near clipping
(or more trickery in the material)
you can make it one plane just past the near clip plane, and render translucent and always on top so it won't clip through things. not sure what distance away would look best
do multiplicative blending, not alpha, for perf

@rare violet Query the device properties from OpenVR. UE4 doesn't include direct support currently, you need to use another plugin or code it yourself.

@tired tree I've tried making a web browser in VR with the VRStereoWidget, but when I try to VR preview it hangs for about 30seconds before starting and then another minute or so later I also lose focus on the player window, I have to click in the preview window again to restore focus and continue in VR.
Is there a known issue with VRStereoWidget?

Given the simplicity of the games for labo, I doubt they release a PRO version
This is just a gimmic for the ones who like to build stuff with the labo cardboard
It's a nice thing if you are interested in becoming a builder of sorts and probably more aimed at the younger generation

Hey, could someone help me with this?
I'd like to scale the world so that it looks like you've "zoomed in" -like how it works in the UE VR Editor or TiltBrush when you grip with both hands? I found someone's blueprints for it here -> https://forums.unrealengine.com/development-discussion/vr-ar-development/96944-using-controllers-to-scale-rotate-re-position-world but as the comments below says, there's a method missing in the screenshots. I've tired implementing a scale on my own, which didn't work, nor could I get the forum version to work. Does anyone know of a way/a guide that could help me in the right direction? I'd really like to do it in blueprints

@digital musk is that with Rift? There are issues with Rift and some stereo texture formats
and no its not a problem with the widget itself, its an issue on the back end

Rift yes. just displaying a browser in a 3dwiget....but using the VRStereoWidget

Yeah, some of the animated scroll widgets also cause it

I did an interview with epic. Subtle unity shade: "Aside from Blueprints, the fact that Epic actually uses Unreal Engine to makes games shows through. The feature sets fit together without any major gaps and you can tell that someone has actually thought through potential problems or encountered and fixed them before you. "

Has anyone been able to get image tracking working with ARKit and Unreal recently? I'm trying to follow this tutorial, but I'm having some issues. https://docs.unrealengine.com/en-us/UE-Dev-Blog/ARKit-15-Image-Detection-in-UE4-420

I can set up the ARCadidateImage correctly and my deployed app can recognize the target image. However, I'm not able to set up the blueprint correctly that will add geometry on top of the target image.
I'm not able to connect the "As ARTracked Image" pin in the "Cast To ARTrackedImage" node to the "Target" pin in the "Get Local to World Transform" node. And in the "SpawnActor" node, I don't know what to select for "Class".
This is the example blueprint that I'm not able to follow

I was able to get this working. I'll post here tomorrow with how I solved it.

I have a VR app in which I want to display UMG for people not wearing the VR headset to press some buttons etc that can be hidden. I thought this was possible in the past, but whenever I start the VR preview the interface disappears. It just works in PIE. Is there a way to get this displayed? With mouse interaction?

Hi there :)
I'm developping an AR app meant to work either with ARKit and ARCore.
I would like to occlude some AR objects behind detected planes, for example when a AR-ball on the floor goes behind the detected plane of a real-table.
I saw in the materials editor that there was a node called "Google ARCore Passtrough Camera", which seems to be what I'm looking for, but is there something equivalent for ARKit ?
(or just another way to occlude geometry than sticking the camera's texture onto objects in screen coordinates)

@tawdry bough I'm sure you can find tuts for swinging mechanics. You could just connect your VR pawn, but I doubt the experience is gonna be pleasant.

Hey there! Does anyone know how I can project a world location onto the screen-space of the actual left and right eye viewports? Only thing I seem to get working is projecting it onto the mirror-viewport
FVector2D FTobiiEyeTracker::ProjectToScreen_Percentage(const FVector& In, EStereoscopicPass Pass, APlayerController* PC)
{
FVector2D ScreenLocationPercentage;
ULocalPlayer const* const LP = PC->GetLocalPlayer();
if (LP && LP->ViewportClient)
{
// get the projection data
FSceneViewProjectionData ProjectionData;
if (LP->GetProjectionData(LP->ViewportClient->Viewport, Pass, /*out*/ ProjectionData))
{
FIntRect ViewRect = ProjectionData.GetViewRect();;
FVector2D Dimensions = FVector2D(ViewRect.Width(), ViewRect.Height());
FVector2D ScreenPosition2D;
FMatrix const ViewProjectionMatrix = ProjectionData.ComputeViewProjectionMatrix();
if (FSceneView::ProjectWorldToScreen(In, ProjectionData.GetConstrainedViewRect(), ViewProjectionMatrix, ScreenPosition2D))
{
ScreenPosition2D -= FVector2D(ProjectionData.GetConstrainedViewRect().Min);
if (ScreenPosition2D.IsNearlyZero()) {
ScreenLocationPercentage = FVector2D::ZeroVector;
}
else ScreenLocationPercentage = ScreenPosition2D / Dimensions;
}
}
}
return ScreenLocationPercentage;
}
This is the function I added which is basically just PlayerController->ProjectWorldLocationToScreen () but also taking the EStereoscopicPass enum, and calculating a percentage rather than the pixel position
But I don't seem to be able to get it work properly within the actual HMD
so my question would be if anyone of you has done something like this already once

That does look badass, but I'm completely immune to VR motion sickness at this point. Do you think normies could handle it?

Yeah is not that bad
it was only bad in testing when I had the velocities wrong and you would spin around objects picking up speed and then get thrown out of the map

I can totally handle it

I still don’t know how to add gravity to a VR pawn
For some reason, the last time I tried doing that it sunk into the floor
How did you add gravity?
tired tree
mmm, well that part you would have to add manually, for my gravity I just let the natural falling state of my VR character pawn handle it
but gravity is easy
its just a constant force applied in -z
tawdry bough
Is that a node or do I set some sort of pawn move to thing and enter -Z in the vector with any contradictory commands canceling it out?
(Sorry If I’m frustrating you, my skills are a little primitive)
As for the web swinging, is it possible to spawn a physics constraint between the object and let it swing from there?
tired tree
You move down or store a velocity and add the gravity to it
and its perfectly possible to use physics instead for the swing
and just follow the hand position to the simulating end
tawdry bough
What do you use for the swing instead?
tired tree
manual logic adding force base on a dot product

I guess this is somewhat marketplace related too but Id rather get VR channel feedback. Anybody recommend any VR assets/plugins? I'm very beginner but I'm planning to make a little VR minigame where you can put your hands in different places and do different finger gestures and have it sort of queue the gestures together and if you do a certain order, something happens. I guess a sort of tree of gestures/positions with the outcomes being at the end of a branch. I expect to need c++ for it. I'm going to dive in regardless but Id love some feedback or pointers if someone has an idea. Thanks!
sturdy coral
@rare violet I don't think it is possible by default but it should be possible with mordentral's plugin
@dusty marten mordentral's plugin has spatial gesture recognition
tired tree
mmm, well you can check property model strings for "knuckles"
but generally now with the new open input you should be checking the tracking fidelity variable which will return if the controller supports finger curl / splay as a generic identifier, the only reason to really check specifically for "knuckles" anymore would be to bind keys and that should already be handled by the action input system.
as for the gesture recognition, to do it with fingers would require knuckles, or leap motion, or a glove, but yeah, I support both hand pose and full motion gestures

They changed things around with the way it renders duplicated static meshes. Essentially makes them work like instanced meshes now and renders them all in a single draw call. So really depends on your scene setup for the difference it will make
sturdy coral
they also seem to have improved multithreading a lot, at least with dx12
quiet badger
While my main project is compiling I tend to hop on my laptop and experiment with ARcore in UE4. Tracking and performance is so much better in 4.22 preview on my pixel XL now
anyway, trying to do a specific kind of set up and I'm wondering a few things
I want to use the AR to do inside out tracking essentially and not overlay the game in the real world, but rather just know where the phone is in the game world space
second thing I want to know is, why make an AR pawn in the template vs just building all that into the player controller so that the controller can still possess an actor if need be
I've switched over to this kind of set up, but now it seems detected planes stay where they are in camera space but not in the world space, meaning I move and the planes stay where they are, but if I rotate they rotate correctly. Was the AR pawn the world origin or something before? I find default template kind of confusing. It's good to learn whats going on I suppose, but totally not a good template to work with
rare violet
Anyone know if its possible to find the trigger axis on knuckles controllers? seems like a boolean on/off
pearl tangle
@quiet badger There was no update in 4.22 compared to 4.21 right? I am having to run on google's branch at the moment because I need 1.7 for a current project which isn't in 22 unfortunately

android-21 worked for me :/

blergh something isnt right with my install then
@mighty carbon what are your target settings btw ?
arm, opengl es , etc.. ?
alright seems I fixed it by installing the 28 sdk
but its crashing on start
ah well
I had a similar crash on 4.20, sadly I cant remember how I fixed it..

I am using ARM 32bit, ES3.1 (also had no issues with ES2)
at work right now, so can't check the target
I think I used 24
but in the settings where you have paths to SDK/NDK, I have android-21 and "match latest"
get logcat to see why it's crashing
@jaunty shell ^^

aight thanks a lot !
I'm using ARM64/ES3.1
at least thats what is matching my target device (a Samsung Note 8)
@mighty carbon from what I see in the log it say it cant find the librarcore library ?

prolly gradle stuff
I switched to phone model instead of the bloated, firewalled network we have at home

@mighty carbon stock DWVR. Same DWVR as the 120 fps build, but without the new shaders ported. Engine version is 100% vanilla
@sturdy coral DX11
4.22 is just straight up faster at anything
its just that if your map contains tons of modular meshes (like mine) the gains are spectacular
mighty carbon
cool
wicked oak
including mobile btw @mighty carbon
and not only that, but mobile gets software culling
from fortnite
i know some dev who is porting his game to oculus Quest and using 4.21 for now, but software culling is huge for him
he made a single occluder mesh for the entire map manually
and use that as occlusion
mighty carbon
and in 4.22 he wouldn't have to do so ?

is there any way to disable stereo and keep oculus touch working?
sturdy coral
@tacit quest Oculus will allow the controls to work when the hmd isn't active, but not the tracking
You'd have to tape something over proximity sensor, or set it always on in the debug tool
And then modify probably engine to send small dummy eye buffers to the Oculus runtime
Not something that could be workable in a shipped product, but you could make it work for you if it is just for during dev
Vive controllers and trackers can work without an hmd running though
tacit quest
thanks. i'm making a virtual camera with touch. if i get some vive trackers i can switch to using the virtual camera plugin, just wanted something to test greenscreen stuff
but it's annoying that i can't turn off stereo. and i also have to carry the headset around so the sensors don't turn off

@sturdy coral I tried the Pimax 5k+, I can't do more than 20s before I get eye strain
I'm on the lower IPD spectrum but it's supposed to support that
sturdy coral
ah that sucks, I haven't gotten any
hallow knoll
The hardware itself was better than I expected
sturdy coral
I think the IPD adjustment only moves the lenses and not the screens behind
so then they are having to do some kind of warp correction
sturdy coral
possibly so, I'm right at 64
unreal has a few issues
shadow fades are done using z buffer cutoffs
and since the screens are canted the z points different ways per eye and you get an artifact

orchid raft
Hey guys, I have a question that may be a long shot
Does anyone know of any UE4 based games, or concepts available that use the motion controls as physics objects? the best "swordfighting" physics currently available in VR that I know of, is called Sword and Sorcery, and it uses this concept to make realistic VR interactions (in Unity) Just wondering if anyone has worked with that idea in UE4.
when I say "motion controls as physics objects": It's more like, your actual controller is invisible, but your hands/weapon is a floating physics object attached to your arm, that follows the invisible motion controller around. The heavier the weapon, the slower it reacts to chasing the "invisible controller" around essentially. giving the impression that the object has weight/momentum (I think?)
sturdy coral
should make it easier to hit min spec for oculus
before you'd have to target dx11 on win7
and still meet their spec
orchid raft
I thought that was included in the October update
was it just now pushed to all?
like BF5 has god rays. that's a DX12 effect
but you need the Oct. update
oh shit
thats windows 7
wtf
tired tree
@orchid raft if you want a basic utilization the PhysicsHandleComponent can be used for physical grips. Its an acceleration based constraint though so it doesn't quite simulate weight that well.
I have an optional branch in my plugin that uses force constraints though for people doing weighted grips that goes a little deeper in that and could be referenced.

@sturdy coral @tired tree you may want to have a look at CALIKO. It is basically FABRIK with constraints support and it has been ported to UE4 as plugin: https://forums.unrealengine.com/community/community-content-tools-and-tutorials/108010-ue4-caliko-port-fabrik-with-connected-chains-and-constraints
sturdy coral
@@dim imp You have to size the spheres to the amount of parallax you want out of them, reflections will be traced against them
box reflections can get a much better result in lots of cases, it will reflect against the box and you can pine it up to walls and stuff
Planar reflections are another option, but usually you would only capture movables and still use box/sphere for the environment
Another issue is static lights inject a big blob into reflection captures, you can disable that through one of the visibility settings on them
And another issue is reflection captures are incredibly aliased and can miss small geometry
There is a supersampling define you can adjust to fix that
tired tree
@sonic lake that would have to be heavily reformatted......
its entirely seperate from the animation system...
sonic lake
@tired tree True
tired tree
its actually fairly useless as is
sonic lake
The solver code is there but it is indeed not integrated into the AnimGraph. That would indeed require some work.
I have planned to look into it later this year. Or an equivalent solution.
Are you referring to the full body IK which someone demonstrated some time ago? That one could handle constraints pretty well.
tired tree
pretty sure the guy that ported that didn't fully understand it and just translated it 1:!
he is using their rotation matrix setup directly with FVectors instead of actually using a rotation matrix in engine...and all of his rotations are also FVectors...
sonic lake
Yes, it was a 1:1 translation, as close as possible to the original

there is an MIT licensed constrained FABRIK setup here too:

Just grab the camera tilt?

That really really sucks @sly elk
Apparently it is affecting also Facebook and the rest of the family
I feel your pain 😦

Is facebook still down?
sonic lake
@abstract forum apparently there are still issues in some locations. Not sure what happened.

ugh- i have people in my discord who siad they tried to buy the game and got an error
that explains the really really poor sales

anyone know how oculus wishlists are supposed to work? I got confirmation that one user who had wishlisted never got a notification or an email
elder echo
anyone have an issue with Valve_Vr.fade causing the image to tear up while fading causing a very unpleasant feeling, the worst part is if i use the Steam Vr dev option to mirror the hmd, the issue does not appear in the mirror, so the only way to show you the issue is by recording one of the eye with my cellphone which makes it very cancerous to debug, ever had something similar?
if i had to describe it i would say it's like the screen is melting while fading, only happens during fade and on multiple headset (i've tested 3 of them)
sturdy coral
@sly elk I wonder if instead of queueing the notifications and sending when possible, they just didn't send any while the system was down and now won't go back and try and send again =/
do you have a contact over there who could check into it?
sly elk
yeah, I do. I think they are figuring it out

Hey guys I'm about to create an AR project combined with VR,
My idea was to have an oculus headset with attached on top a stereo camera (zed mini maybe ? ) So that I could easily swap in Unreal between AR and VR... What do you think can be the best hardware camera other than the zed mini ? to give real life, immersive stereo vision ?
flat shoal
@distant spoke the ones on the HTC Vive Pro? 😛
distant spoke
@flat shoal nnnnnoooooooooo 😱 😱 😱 😱 😱 😱 😱
flat shoal
it's the easy answer, it already does what you're asking for
also, no Facebook, which is a plus
either that or Hololens
not sure if the WMR headsets also do it
but WMR support seems to be nearing end of life...
distant spoke
Uhm what about a 3D party camera to attach onto the oculus headset ?
sturdy coral
@distant spoke oculus doesn't have an HMD usb port like vive/vivepro/pimax, so it is a bit of a pain
WMR can do it but I don't know if they expose the API (and the camera width is so wide it would be far off of IPD)
distant spoke
I found a good comparison between the Vive Pro and the zed mini
I think zed mini has to be the best for my rift
mighty carbon
@distant spoke is there some plugin to make use of ZED Mini + Rift in UE4 ?
quiet badger
@pearl tangle yeah i had to grab some source from a github project, but it's the latest stuff running in ue4, I got it in 4.22 as well

4.21.1 lock to HMD on my character BP's camera doesn't seem to work. Still rotating around the character instead of being static. anyone know what's up?
mighty carbon
Hmm.. So Synty's assets are shit for mobile VR 😦 Going to have to re-model most of them :/
Rumor has it that Quest and Rift S is the same device 😃
rustic cargo
Doubtful, It'd be too expensive
although an HMD that can run standalone + wired should be possible
real needle
how to prevent rotation of HMD around thirdpersoncharacter? Lock HMD doesn't seem to solve? some other setting must be fkng it up
real needle
I got the camera functioning the way I wanted it to if anyone ctrl+f this and needs help with something similar I'll try to help you

packaged VR project has a triangle artifact type thing with blurred colors which appears on the right hand side of of the headset. WMR lenovo explorer if it matters. anyone know whats up?
cerulean mulch
hi guys can unreal be used to create AR application for both IOS and Android platform? just by using unreal can we achieve one development launch on multi platform ? My company have developed an AR for IOS platform and we need to have on android as well and i have difficulties explaining to my director of the company that UE4 might be the best choice as i love to work on UE4 instead of others.
as our app have an overwhelming responses from the users , they requested to have it on other platform like android and possibly windows phones too
real needle
happens in vr preview for VR template as well for some reason. But it doesn't happen in the VR preview of my main project lol
sturdy coral
@real needle looks like bug in the hidden area mask, I don't know why it would only happen with one project and not the other
are you on steamvr or native wmr
pearl tangle
@cerulean mulch Windows phone is completely dead so you wont get anything running on there. No idea what it is that you have built with AR but UE4 supports ARcore and ARkit and you can publish to both with potentially no code changes at all
ARcore works across both iOS and android as well, compared with arkit which only runs on iOS
arctic path
Is it possible to have a player in VR but be displaying a different screen on their monitor that is still interactive?
For example on the monitor is a widget with buttons, and in the VR headset is a separate view
pearl tangle
@arctic path yep. Spectator screen and then some messing around
real needle
@sturdy coral WMR but steamvr is installed
arctic path
@pearl tangle Ah good idea. Thanks!
sturdy coral
@real needle but which are you using in your project? steamvr plugin or wmr plugin
real needle
@sturdy coral ah. well I have both plugins enabled. WMR launches when the packaged game launches. Could having both plugins enabled be the probleM?
sturdy coral
@real needle no, it picks them based on a priority
it was broken in 4.19 or 4.20 until one of the hotfixes I think, but unrelated to your problem
it just picked steam over WMR by default until a hotfix, now defaults to WMR
real needle
i wonder if it's a lenovo explorer issue
wmr
i made a post on the AR/VR answerhub ]:
i also made a post on the looking for talent on here for someone to try and help me fix it lol

bad ass @mighty carbon thank you so much for sharing, I've been waiting for this since the announcement at OC5 !
flat shoal
how do you guys test how the change of a float variable impacts the game? do you play and stop between every change?
or is there a way to just adjust the value while playing that I haven't discovered yet?
sonic lake
@flat shoal you can create a 3D widget for that or simply set two keys to increase / decrease the float value. In VR the second option is probably easier.
flat shoal
that's amazing... how come Unreal Editor feels like a decade behind Unity in this aspect? and how come people who use Unreal think this is normal, and most importantly of all, how come nobody is saying anything? There's like 1 thread in the forum about this 😃
nova wave
It’s not really engine specific, 0lento was suggesting to use midi keyboard to tune values in real time years ago
Otherwise having a widget is enough
sturdy coral
@flat shoal not exactly what you want, but 4.22 adds umg editor widgets
@flat shoal you could make a widget and use this to set any property by name at any time, as long as you can figure out how to pass the object reference you want to set it on:
flat shoal
@sturdy coral but do you do non VR development? if you simulate in non-vr mode, you don't have to do that, I think? just adjust the value in the details panel?
sturdy coral
I don't remember if you can enter a value in eject
You can definitely drag things around
It may depend on the uproperty specifiers
(EditAnywhere)
If you want to change a class default value that is a lot harder to do genericly, things may have already read the CDO at runtime and stored something derived from that value somewhere else, etc.
sturdy coral
in VR you can't eject like that though
flat shoal
I was just talking about public variables that you can access through the details panel of a blueprint actor

4.22 psvr (dwvr) is instacrash on load
mighty carbon
I truly hope that new batching in 4.22 works on Go/Quest
mighty carbon
@sturdy canyon do you know if new renderer works on Go? I'd rally hate to remodel a ton of Synty's assets (which I probably have to do anyway)
sturdy canyon
I finally got a build to run on Go, yes
But instances stereo didn't work, so it was a net loss for me

nativization going pretty wrong here
sturdy canyon
I have zero animations, so maybe I'm in the clear
wicked oak
it runs without nativization
gonna try the release mode
got it to run
there is an improvement, but my 4.20 version is fastaer (due to my optimizations)
the gpu trace capture looks quite different
but i havent gone deep into it to chec kthe autoinstancing
mighty carbon
So basically 4.22 is the same as 4.21.2 ?
For Go/Quest that is
@sturdy canyon @wicked oak ^^^
sturdy canyon
No
For me it's a step backwards. I believe the auto-instancing works, but multiview doesn't
Some apps might get better perf on 4.22 depending on how much auto instancing happens. I got significantly worse perf due to loss of multiview
I have not confirmed that auto instancing works. Just that my total perf is worse for now
mighty carbon
Hmmm
I guess I am gonna have to stay with 4.21.2
I think Carmack said mutiview is a must on mobile VR
So if that doesn't work in 4.22, then it's no use for most projects
sturdy canyon
There is a chance it will be fixed by launch. Or fixed on the Oculus Branch in 4.22, then merged into 4.23 standard
mighty carbon
🤞
pearl tangle
You can just write a script that will automatically replace all your static meshes with instances. I had a good 1 I did a couple of years ago for that, gave insane performance increase when building cities
mighty carbon
On mobile VR @pearl tangle ?
In my experience ISMs don't help much with performance on Go
sturdy coral
depends if draw call bound or not. just instancing everything can add geometry burden because they don't get culled so you have to balance
with the new auto instancing I'm pretty sure it supports culling
pearl tangle
yeah HISM vs ISM is likely more what you want, but every optimization setup is dependent on your stuff in general. Not many fix all solutions
mighty carbon
HISM tanks performance on Go
ISM works, but then LOD is useless for large scale ISM. I use ISM for chandeliers flames for example.
Unity had batching since version 4. Culling worked fine with it.
wicked oak
@mighty carbon you want to run 4.21 due to the fortnite software culler
unity cull is worthless trash
ive worked with it on gearvr games
mighty carbon
So unless it's differently implemented in UE4, autobatching + multiview should be beneficial for almost any scene that is heavy on drawcalls and duplicate geometry
wicked oak
unity does merge drawcalls
actual merging
if you have mulltiple meshes on the same mat, it will try to merge them dynamically
that makes unity significantly stronger due to that. You can do it manually in unreal, of course
but doing it is crappy
mighty carbon
Well, that sucks.. I thought 4.22 batches like Unity
wicked oak
no, its a different thing
4.22 has a renderer that keeps all scene data on gpu, and when its going to render, its only sending the index
it improves bandwidth and "driver stuff" significantly
the autoinstancing is just an extra feature it can do
unreal engine does not try to merge objects becouse they kind of expect their devs to be decent
unity does becouse most unity devs are noobs and use like 10 polygon objects as individual
so the merger is pretty useful
the merging does take a good chunk of cpu power and extra memory, and it fucks pretty hard with the culling
but unity culling is worthless anyway
mighty carbon
Hmm
No wonder most Go games are made with Unity
I guess there is no escape from remodeling Synty's assets 😒
quiet badger
@mighty carbon yes and no
synty assets are terribly made so you should want to tweak them anyway
mighty carbon
Well, you can't really make it too different if want sharp edges

@hallow knoll by chance, are you going to be at Oculus booth at GDC ? Just wondering if they announce anything UE4 related (like, working mobile Vulkan or some other goodies for Go/Quest)
wicked oak
OpenXR my mates
and ue4 will support it
i wonder if they will add the plugin for 4.22 release
hallow knoll
I don't think I'll have time to do any demos during the show I'm afraid
wicked oak
just dropped the preview spec
and an actual godot implementation
wich is a pretty big "what in the fuck"
specially given how hard godot sucks for vr
hallow knoll
@wicked oak link?
wicked oak
btw, the related part from the openxr announcement
"Epic believes that open standards like OpenXR are essential foundations for a vibrant, multi-platform VR and AR industry in the coming years. We've supported OpenXR since its inception, including powering the first public demo of OpenXR at SIGGRAPH last year, and hope to see the ecosystem continue to grow with the first public release of the spec at GDC,” said Tim Sweeney, founder and CEO of Epic Games. “Epic plans to continue supporting OpenXR in Unreal Engine 4."
tim says ue4 has supported openxr from a while ago, and they will continue supporting. So i expect the plugin to be public for 4.22
mighty carbon
I'd like to know more about Go/Quest performance optimizations in UE4, if any

ue4s VR infrastructure got re-named to XR on the back end and a lot of the stuff got standardized from 4.18-4.21
they have been prepping for it for awhile
granite jacinth
@wicked oak So, your best guess when it will be implemented in UE4? Non VRWorks
wicked oak
@granite jacinth read it
they already have it working in ue4
With their initial proof-of-concept usage of VRS in UE4’s Sun Temple, they were able to show a significant performance win.
i guess its not going to take long till its made official
granite jacinth
Ah, missed that somehow
But anyway, still only NVidia cards, but at least that's on the user's end
Intel next
sturdy canyon
Since 4.9 (when I started VR Dev) there's been like 4x improvement just in engine badassery.
I think early launch titles probably have little trouble maintaining similar Fidelity on Quest
Other than triangle counts and crazy shaders, I guess..

hey guys. I'm currently working on a project for a museum exhibition and apologize in advance if I post this at the wrong place. I am pretty much a bloody noob but I want to work my way into this. so, my general question to begin with: can anybody tell me with certainty that it's (not?) possible to import complete tilt brush models (including textures) for further editing in unreal? the most constructive answer I found on the web is to export the model from unity to a file format that works with unreal. can anyone confirm this as the best method? thank you for any help.

Has anyone figured out the material wizardry needed to play a top/bottom or left/right stereoscopic MP4 video from a Media texture for mobile VR?
silk lodge
@white fern I think using instanced stereo breaks that
white fern
@silk lodge Not sure what you mean by that.
silk lodge
@white fern it's a setting in rendering settings in the engine
white fern
Theoretically, all I need to do is find a way to discriminate between each side of the video and plug it into the Mat_Stereo_Image found in the docs.
silk lodge
I had 2 meshes, and offset the UVs so each mesh would get half of the video
white fern
So you didn't use a sphere @silk lodge ?
silk lodge
you're looking for spherical video?
