that does look pretty sweet

#

Looking at that video at the bottom. I mean, Just getting a motion controller's transforms should be enough to drive that IK right @tired tree @sturdy coral ?

tired tree Nov 29, 2018, 4:21 PM

#

well, you would have to set limits

granite jacinth Nov 29, 2018, 4:21 PM

#

Sure

#

But, this could be something for quick prototyping, or even implementation for a game

#

If you don't need anything more advanced

#

(although it does look like it could get more advanced)

#

@sturdy coral After you've played with it, can you do a package and see if it works in a build?

sturdy coral Nov 29, 2018, 4:30 PM

#

Ideally epic would include a rig similar to art tools but made in this

#

I'm sure they have it, but it is on a fortnite skeleton :P

#

At some point they need to release mannequin 2.0 and just make it use the base fortnite skeleton

granite jacinth Nov 29, 2018, 4:39 PM

#

@sturdy coral what's the difference?

#

Is there a talk?

sturdy coral Nov 29, 2018, 4:56 PM

#

there are a couple ones on their youtube channel from their dev days thing

#

probably mainly just bone names or number of spine joints, but they may have a different setup for twist correctives and stuff

#

but I think just have one base male and female skeleton that things are authored to, but they use different proportions and animation retargeting across characters

tired tree Nov 29, 2018, 5:02 PM

#

are they x+ forward facing? @sturdy coral that would be the real question :p

granite jacinth Nov 29, 2018, 5:16 PM

#

I doubt we'll ever see Epic go x+ for art

#

even though X+ is forward

#

Nope, we'll be rotating the damn things 90 degrees everytime

but it will be really flexible

fleet plume Nov 29, 2018, 10:30 PM

Anyone know how to detect if a Vive is being worn? In the editor "IsHMDWorn" enum always returns "not worn" and in a packaged build, it always returns "Unknown"

sly elk Nov 30, 2018, 2:44 PM

#

I think we use the "isHMDWorn" without issue

spare yew Nov 30, 2018, 2:50 PM

#

And you are using a Vive?

tired tree Nov 30, 2018, 2:58 PM

#

@spare yew what engine version are you on

#

also the vive IsWorn is on a delay after setting it down

spare yew Nov 30, 2018, 2:59 PM

#

I'm on 4.20.

#

I figured it was on a dely like it is with the oculus but the issue is it always returns "not worn" in editor and "unknown" when packaged.

trail shale Nov 30, 2018, 3:50 PM

#

@clear inlet i just tried them and met with their CRO, I was pretty impressed - they definately need more work with the integration but the hardware is really precise, mainly I think the collision needs to be played with software side - they have their plugins but nothing in blueprint or code I could tweak

#

Although that might still be proprietary too

#

I think they are at the equivalent of a DK1 or earlier version of the Oculus and in their development

#

But I would bet on them for sure, unless someone else can somehow destroy them on cost of hardware to produce Haptic gloves

#

@spare yew there is a bug, or was, that the worn state won't get updated at the very start or something like that

#

I think it may have just been the worn delegate

#

steamvr doesn't send 'vr::VREvent_TrackedDeviceUserInteractionStarted' if you start the app with the HMD worn

#

not sure about started not-worn

#

it may only be an issue if the app doesn't have bStartInVR=true, I can't remember

sturdy coral Nov 30, 2018, 10:25 PM

turns out there used to be a full mannequin control rig included with the control rig plugin, but it was removed in 4.20, and the plugin was reworked so you can't just migrate

I'm using F6 > Execute Console Command "Stat SceneRendering" from my level blueprint. The problem is the stats show top left in the HMD view and so I can't read them. Is there any way to centre the stats or maybe there's a dedicated command for VR optimisation stats?

Is hardware occlusion working with ES3.1 on Oculus Go? I'm doing some tests and I get the same number of drawcalls and prism when i'm infront of a wall :/

mighty carbon Dec 2, 2018, 12:52 AM

#

I think only software occlusion work on Go @ivory flower

#

Check Oculus forum for details

ivory flower Dec 2, 2018, 8:22 AM

#

Thank you, I was looking but I can't find a confirmation. I'm trying with OpenGL 3.1 but it seems there isn't any difference with Occlusion Culling on/off and Software Occlusion on/of. I will try with OpenGL 2 now

ivory flower Dec 2, 2018, 9:03 AM

#

Umh I can't notice any difference with Occlusion Culling + Software Occlusion enabled/disabled in any case (testing a scene with almost 600 drawcalls and 300k triangles)

ivory flower Dec 2, 2018, 11:57 AM

#

ok, I forgot to change the the LOD for occluder mesh to 0, now Software Occlusion works for 2 and 3.1 but it renders 3 times slower :/ I unchecked software occlusion for 3.1 and it does nothing, I guess there is no hardware occlusion for Oculus Go

mighty carbon Dec 2, 2018, 2:51 PM

#

Yeah, that's what I keep saying, but some folks swear by ES3.1

#

Hopefully when Quest is out, we get Vulkan on Go/Quest

ivory flower Dec 2, 2018, 4:04 PM

#

yep, they announced roborecall for quest so I hope we will got a ton of improvements for mobile VR, I'm having problems with some models with ES2 (meshes are not visible on the device) but I can't switch to ES3.1 because then some of my shaders break 😦

sturdy canyon Dec 2, 2018, 5:24 PM

#

Vulkan works for me in 4.21, but multiview doesn't and fixed foveated rendering doesn't.

#

Tested on both the Go and the Quest

#

Render thread time was about even since you lose multiview. But GPU time worse since you lose Foveated :-(

#

I believe Epic is waiting until after the render graph refactor to fix multiview in vulkan.

mighty carbon Dec 2, 2018, 6:08 PM

#

Vulkan is missing critical extension that Oculus requires to render in VR (that's my recollection of it after reading stuff and listening to Carmack).

#

And without it there are no performance gains compare to ES2

#

Mobile VR without multiview and FFR is horrible idea kappa

wicked oak Dec 2, 2018, 6:10 PM

#

@mighty carbon probably its an extension for the timewarp or similar

#

the idea of vulkan is that you dont even need multiview

#

becouse you can just record the command buffers from one side and run them again

mighty carbon Dec 2, 2018, 6:17 PM

#

Maybe, I don't really know all the details 😊

sturdy coral Dec 3, 2018, 4:00 AM

#

@ripe lotus use 'get motion source' instead; it is an FName instead of an enum and can be things other than left/right (mainly for vive trackers)

#

you can just convert it back to your own hand enum if you know you don't need to represent things like vive trackers

I think EHand already had some tracker related stuff, but wasn'tt flexible for the future if new devices are made

Hi, I've got a question. Let's say I want to learn working with VR. Would it be handy to first work / learn the engine on just a flat screen and later move to VR, or could I start with VR without running in to problems as someone who is really new to this engine and only made a flying cone? 🤔

jaunty shell Dec 3, 2018, 10:21 AM

#

@wheat holly I'd say get to learn the engine first, then move on to VR

#

Generally camera effects are turned off in VR

#

But that general rule dates back to the same time frame when everyone was certain that artificial locomotion was not okay

#

So maybe it has its place. But probably it doesn't.

#

Follow your heart. Test with experienced VR players as well as with newbs.

frigid kite Dec 3, 2018, 7:40 PM

I think a strong vote against it is that our eyes don't work that way - when we look at something, it comes into focus. So until we have eye tracking, I would personally steer clear from DoF in VR

ok I have a question, I am working on a survival horror game and I want to be able to have people to crouch and hide under desks and such, what would be the best approach to this, a button to crouch or an actual crouch in real space?

fleet plume Dec 4, 2018, 8:13 AM

#

i'd personally go for real crouching., though i guess you'd have to make sure that the desks aren't too small

#

would be amazing if players not crouching actually generate noise and attract enemies

quiet swan Dec 4, 2018, 1:52 PM

#

but since everyone is a diffrent size will it work?

#

like a 6 foot 5 guy might not be able to fit into the area?

dim iron Dec 4, 2018, 1:59 PM

#

if its based of the height of the hmd then it wouldnt matter as long as they got there head close to the floor?

pearl tangle Dec 4, 2018, 2:08 PM

#

if the guy is 6 foot 5, then he is not going to be very good at hiding under a desk. Which makes things accurate

#

same way that if you put a bunch of items on a high shelf then a short person isn't going to be able to reach them

sturdy coral Dec 4, 2018, 4:38 PM

#

crouch button can be nice if allowing seated play

#

skyrim has it

#

I think they needed it for sneak too, kind of annoying because you wouldn't enter sneak when naturally crouching

granite jacinth Dec 4, 2018, 4:43 PM

#

@sturdy coral yeah, but how would you even do it? I guess if you measured constantly if the height of the HMD is below a certain point , they are crouched/stealthed. Maybe it's not that costly as I am envisioning it

#

get user height in beginning. maybe do 60-70% of height as crouched

sturdy coral Dec 4, 2018, 4:44 PM

#

yeah

granite jacinth Dec 4, 2018, 4:44 PM

#

I'm over here trying to crouch, it's hard

#

lol

sturdy coral Dec 4, 2018, 4:44 PM

#

calibration step at the beginning would be best probably

#

but you could also try and work it out over time

granite jacinth Dec 4, 2018, 4:44 PM

#

Yeah, I mean, the thing is

#

People like to dodge

#

Weave

#

It may trip that crouch logic

Hey there, currently working with ARCore, quick question: Is there any good way to scale and position a level ?

#

I do have a "normal" scaled level and want to spawn it in my AR Map, right now I use "World To Meters" to reduce the size of the whole world, so the spawned level is small

#

but that will also hurt the accuracy of the ARCorePlane

#

So I was wondering, if there is a good way (besides designing the map on a smaller scale)

sly elk Dec 4, 2018, 7:12 PM

#

question for you all on vive controller mapping. I am planning to bind what were the analog sticks on the rift to the touchpads on the vive- By default when you touch part of the touchpad it reads the location of hte touch, and treats that as an analog input of that direction/scale as if it was a stick in that orientation. My plan is make the touchpad input work like a swipe where it only registers teh relative change in touchpad position (so it subtracts teh starting position). This is so I can use the button inputs on the pad at the same time as the analog inputs

the oculus software on the go is on version 3.38 (probably the release version, the newest seems to be 3.45) ... how do i force an update?

you have to leave it plugged for charging and leave it on. Updates will propagate eventually. 3.47 was the last version I had and that was a few month ago.

We would like to start a cardboardVR app in 2D mode with "hmd-like" tracking and allow the user to switch to VR mode for cardboard in the app. This seems to be quite an annoying challenge with UE4 though. If we have googlevr support enabled, our display goes to stereo automatically. We've checked off "start in VR", thrown BP nodes like EnableHMD off and Stereo Off, and nothing seems to work. We'd like to harness the hmd for tracking purposes, but toggle stereo display on and off at will. Any thoughts as to how this might be done? The project is built in 4.19, btw.

They actually have someone test the game and make sure your store claims are accurate

#

I'm sure it's farmed out to china or whatever, but they apparently at least try to verify your store descriptions aren't total horse shit

granite jacinth Dec 6, 2018, 11:46 PM

#

@sly elk @wicked oak lies

#

They were pretty damn thorough for CVR

#

They check Store Page

#

You have to make sure what you put on Store Page matches in game

#

Specifically, if you say you have coop MP, they want to see that option in a menu or something

#

Other than making sure it "works" and in-game matches Store Page I don't think they do too much more

#

@sturdy canyon Ah, you pointed out the store page stuff already

@sly elk Did you all set up different branches for Oculus Store and Steam?

sturdy canyon Dec 6, 2018, 11:53 PM

#

The only thing you have to do is toggle on Oculus DRM and delete the Steam and OpenVR folders from your build

#

So if you set up a config var for whether to run the DRM, that's all you need to change between versions

#

Everything else we do at runtime

#

You can't do runtime checks for DRM, because some Oculus users might buy your steam version

I used the default VR demo

tired tree Dec 7, 2018, 2:05 PM

@north relic looked fully at that BP graph...you aren't rotating by 15 degrees, you are SETTING rotation to that rotation amount value. You aren't sampling the current starting rotation anywhere.

#

also in roomscale that won't be the result that you intend, you need to offset by the hmd location as a pivot

north relic Dec 7, 2018, 2:25 PM

#

it's relative location, so shouldn't that work anyway? and why would I need to offset the HMD? because the pivot point is not at the centre of your head?

tired tree Dec 7, 2018, 2:30 PM

#

@north relic relative location of the actor...is the actors world position, its not relative to anything but the world. Also the actors zero point isn't the same as the HMD location, so rotating the actor with the HMD offset will move the hmd in space around the actor zero point

sturdy coral Dec 7, 2018, 4:40 PM

Anyway, on Oculus GitHub account they have examples that we are free to use. One in particular, the HandSample, seemed like a good starting point for me. I was able to run the project flawlessly using the Oculus branch. After migrating the VRCharacter blueprint and the associated assets to my project. . . I can see the hands but not the animations. I've been looking through their project, which is BP based, but can't figure out how the map the motion events to the animations. Does anyone know how this done?

The IsHeadMountDisplayConnected() and IsHeadMountDisplayEnabled() both work fine in the editor/VR preview but always returns true in the packaged version.
Using UE 4.18 and HTC Vive. Any suggestion on how to solve this issue ??

@sturdy coral I'm not certain of what I'm doing. Is this the Motion Source that you are referring too? I tried changing it to LeftHandCenter, tried checking Disable Low Latency, and tried changing the Player Index. Nothing worked. The settings in the image do work as far as rendering the orientation and tracking of the hands. But unfortunately no animations. Am I looking at the right place? Making the right change? Any other suggestions? Shoot what you stated sounded promising 😃

sturdy coral Dec 8, 2018, 7:14 PM

#

@rigid lodge yeah, look into the blueprint nodes for references to motion source, tracking source, or hand

#

I'm not sure that it is what is the issue

#

find where it queries cap sense values to animate the fingers and add breakpoints etc.

#

but always google a lot before going that far, to see if anyone else is running into it

sturdy coral Dec 8, 2018, 7:47 PM

#

@rigid lodge I might be sending you down the wrong track since they seem to just use a separate left and right class and don't distinguish the hands other than in the motion controller parent of those classes

#

you'll probably have to break out the debugger

rigid lodge Dec 8, 2018, 8:39 PM

#

@sturdy coral I did notice that the Migrate asset left out quite a few animations. Closed my project and copied everything manually. No luck though. Should there be any mappings in Project Settings::Input?

#

Are you thinking that it may have something to do with the Oculus Plugin code?

sturdy coral Dec 8, 2018, 8:52 PM

#

@rigid lodge did you try it as just a template project without migrating?

rigid lodge Dec 8, 2018, 9:03 PM

@sturdy coral Do you know if creating a VR template from the Oculus branch will include the hands too?

#

I'm loading the Oculus code via Visual Studio now.

sturdy coral Dec 8, 2018, 9:08 PM

#

I think it will

#

I have it migrated to my stuff but am just using the animated controllers and haven't tested it in a long time over a couple engine upgrades

#

and I'm feeding in the data to it a little different than it was by default I think

rigid lodge Dec 8, 2018, 9:13 PM

#

Got it. Good to know too. In either case, if the hands aren't there it does give me another opportunity to test moving the assets to my just created VR Template using the Oculus branch. It would be reasonable to expect the hands to work using the same baseline (plugin, engine source, etc.)

#

Btw, I'm using the latest UE4 4.21.1

#

I need to head out. . .but I'll let you know the results when I can. Thanks for the help 🙂

rigid lodge Dec 8, 2018, 11:53 PM

#

@sturdy coral the VR Template generated by the Oculus branch is the one from Epic. It has the UE mannequin hands and animations. The newly generated project did work.

#

So I decided to try and move the UE4 mannequin, blueprints, animations, and input mappings into my own (existing project). Sadly, the animations still didn't work. As with the Oculus version, I can see the hands and the track properly but the animations aren't there.

#

There is a BP_MotionController blueprint class in the same folder where the MotionControllerPawn is. What I don't see is where the pawn uses the blueprint. Do you know where that assignment is?

@sturdy coral yea, that is the one that I started with: HandSample. Now it gets a little more interesting. Neither set of animations are working for me in my own project. I can open and run the Oculus HandSample without issue. I can create a project using the UE4 VR template and it works without issue. The problem I have is after copying/migrating all the assets into my own project, from either version, the animations don't work. The hands are visible. Moving the hands show correctly. But I cannot close the hands, or point, etc.

@sturdy coral It turns out that when I swapped my first Widget Blueprint (containing a simple image) with a more complex Widget Blueprint that included many different UMG controls caused my animations to stop completely. This begs the question, which UMG widgets can be used for 3D widgets (https://docs.unrealengine.com/en-us/Engine/UMG/HowTo/InWorldWidgetInteraction)?

#

.

#

My MainMenu screen widget, based off of UUserWidget, does render in the scene. It has a lot of controls: texts, buttons, images, and a widget based off of SCompoundWidget.

#

.

#

This was a first stab at seeing if it would work. And as I mentioned it does render but has a side effect of stopping the animations. Have you done any UMG or other UI elements with VR? Did you use the 3D widgets approach as shown in the link? Can compound widgets work in this manner?

sturdy coral Dec 9, 2018, 11:13 PM

#

@rigid lodge I don't understand how that could mess with hand animations

#

I've run into one issue with 3d widgets, they opened a ticket for it here: https://issues.unrealengine.com/issue/UE-62154

#

the workaround is to disable widget fast path

#

and I think you have to disable it in code or it will get wiped out in standalone or something, can't remember the exact details

#

it was only for comboboxes that I ran into it

rigid lodge Dec 10, 2018, 12:15 AM

#

@sturdy coral That does give me something to go on. I'm baffled as to why it would interfere with the animations too. As I mentioned, my class structure is based off UUserWidget, and I do have SVerticalBox, SListView, SHeaderRow, etc. contained on one Widget Blueprint. Is it your opinion that this should work?

sturdy coral Dec 10, 2018, 12:39 AM

Yes, I've seen the Widget Interaction Component and the 3D widget docs (https://docs.unrealengine.com/en-us/Engine/UMG/HowTo/InWorldWidgetInteraction).

#

I have a UUserWidget that, when loaded, stops the animation of the hands. I'm trying to figure out what happened. I do have a custom widget based on SCompoundWidget that contains an SVerticalBox, SListView, and others. In my UWidget that contains the SCompoundWidget, the code is pretty light. However, the UUserWidget, which is the outermost class, uses native functions such as NativeConstruct, NativeTick. And my question is. . . could these cause the hand animations for the mannequin to stop.

sturdy coral Dec 10, 2018, 9:03 PM

#

@rigid lodge I don't know if this is it, but make sure you are passing FReply::Unhandled on the motion controller key events if you are doing stuff in slate, so you don't consume them before oculus gets them

#

I think they are polling key status and not using events though

#

and if it is in a WidgetComponent it shouldn't get them anyway, since that should be through a virtual slate user

#

just make sure if you added it to the viewport too or something you aren't consuming the motion controller events

does other stuff work, like trigger?

soo 1070ti equivalent I guess ?

@jaunty shell ah yeah, the 1080 stuffed alienwares are almost out of stock in Netherlands. also I hear a lot of heating problems with new alienwares

From benchmarks the 1080 Max-Q seems like 15 percent better than desktop 1070

you wouldnt expect these kind of GPUs to run cold though

considering the dumbed down cooling system in a laptop :p

hmmm lets see how it goes. another question .... are you fine with the ports on your alienware ?

#

enough for 3 oculus sensors for example ?

jaunty shell Dec 12, 2018, 9:30 AM

#

nah

#

we're using the vive

#

so one USB only

#

but yeah, two full size USB ports is too short

#

there's an USB C port and a thunderbolt enabled usb C port in the back though

dusky moon Dec 12, 2018, 9:31 AM

#

ok I see ... good for next-gen stuff

jaunty shell Dec 12, 2018, 9:32 AM

#

video ports are good (HDMI + miniDP), although the vive wont work with the HDMI

#

we have to use a miniDP to miniDP to plug the breakerbox

dusky moon Dec 12, 2018, 9:32 AM

#

why the vive shouldnt work with the hdmi ?

jaunty shell Dec 12, 2018, 9:33 AM

#

no clue

#

actually

#

afaik the HDMI is linked to the intel GPU

#

where the miniDP is directly linked to the Nvidia GPU

#

VR headsets hate integrated GPU ports

dusky moon Dec 12, 2018, 9:37 AM

ah that's actually stupid to have it connected to the intel 😐

@sturdy coral thank you very much for your help. I do have the animations working. My blueprints were setting the input mode to UI Only, which I removed completely. Sadly the BP OnClicked event isn't firing. The WidgetInteraction is clearly working in my scene using the same control as described in the UE4 docs (https://docs.unrealengine.com/en-us/Engine/UMG/HowTo/InWorldWidgetInteraction). Every time I pull the trigger on the controller the count increases without fail. But an UE4 button contained in a vertical box doesn't trigger the on clicked event when pressed. I know it is pressed because the Pressed Sound is played. And I've looked through my code for the FReply as you mentioned above and made sure to return FReply::Unhandled() to give Oculus an opportunity to respond to the events.

sturdy coral Dec 12, 2018, 9:49 PM

#

@rigid lodge you may need handled for it to trigger the on clicked , but only for the mouse events and not others

#

I'm. It sure, I haven't done user widget stuff, mostly just slate stuff

#

The widget fast path problem could also be part of your issue, it was something with compound widgets throwing it off

#

I can't remember all the details

sturdy canyon Dec 12, 2018, 10:09 PM

Yeah Epic is not doing the Robo Recall mobile port

That does it globally though doesn't it? Won't all the pawns get that?

sturdy coral Dec 14, 2018, 11:13 PM

you definite want the head movements scaled like it does or it will cause sickness

#

@slow swift it is global, you'll have to write some management code to switch it on and off when possessing different pawns

#

loading levels, etc.

#

if you always use camera components you can probably make a derived camera component that handles it and can be set on placed objects in map etc.

Hmmm, bummer it's not camera specific by default. I'll give that a try @sturdy coral , thanks

sturdy coral Dec 14, 2018, 11:16 PM

@slow swift since it affects hands too the pawn or some other management layer will probably want to be aware, if it is displaying motion controller representations it needs to scale them up etc.

sturdy canyon Dec 15, 2018, 12:56 AM

it hits a check() in initiating the viewport. Apparently width/height 0 are passed in

#

I haven't tried commenting out that check to see if it can just run a dev build without it

#

instead I just flipped the bool bUseLoggingInShipping = true;

#

But you also have to make a change in AndroidMisc.cpp for that bool to do anything

#

line 106 is:
#if (!UE_BUILD_SHIPPING)
it should be #if (!UE_BUILD_SHIPPING || USE_LOGGING_IN_SHIPPING)

#

(that took me 6 hours to figure out)

mighty carbon Dec 15, 2018, 1:05 AM

hopefully Oculus will fix dev builds

#

but, since neither Epic doesn't care much about mobile VR nor Oculus care much about UE4 (for mobile VR), docs are always outdated and there have always been issues with deploying /running UE4 apps on Gear VR / Go.. That's why 99% of project there are Unity-based

All of a sudden I can't run my vive in unreal anymore, it worked all day and then suddenly not anymore. The screen just instantly blacks out and steam vr says unreal is not responding.

sturdy coral Dec 15, 2018, 9:11 PM

#

@sly elk if you have both included it picks native oculus with a higher priority

#

There is a command line option to force it too, -hmd=Oculus or something like that I think, that you could put into a steam launch option

sly elk Dec 15, 2018, 9:50 PM

#

okay. so if you play on rift through steam it should default to running oculus?

#

thats good

#

thanks

sturdy coral Dec 16, 2018, 2:07 AM

#

@sly elk yeah, you can override it in your engine ini too, but the engine's BaseEngine.ini should already have it

#


[HMDPluginPriority]
; Since SteamVR also works with the Oculus Rift and Windows Mixed Reality, give priority to the native Oculus and Windows Mixed Reality plugins before trying SteamVR
; Since OSVR also works with either Oculus Rift or SteamVR, give priority to either before OSVR
WindowsMixedRealityHMD=40
OculusHMD=20
SteamVR=10
OSVR=5
WindowsMixedRealityHMD=3

#

that's from my BaseEngine.ini, windows mixed reality showing up twice is a bug that they fixed in a later 4.21 revision

Can anyone show me a good implementation of attaching the motion controllers to open something while constraining the direction of movement? I tried the VR interaction one that uses a drawer but they use a different method and hide the motion controller I believe

sly elk Dec 16, 2018, 4:56 PM

#

oops, I thought this was our PM chain still 😃

trail shale Dec 16, 2018, 4:57 PM

#

I've tried SetWorldLocation and only updating the axis I want movement in based on the WorldTransform of the Motion Controller, and then using the fixed axis that is saved to a variable once you grab it

#

no worries, let the world see, someone else might learn too

#

I'm trying to 'grab' a valve and pull it out with the motion controller, by constraining two of its axis of it to a previously saved ValvePos variable (once you grab it) and then updating the movement axis from the world position of the motion controller. However, WHICH motion controller element do I use? Do I use the base motion controller, or the hand mesh, or the root, or the collision box? It seems to do...weird things.... not sure which order to attach either, I feel like one way would be hiding the motion controller and spawning a grabbed hand mesh and just taking the position of the now invisible motion controller. But again, some direction would be greatly welcomed

glossy agate Dec 16, 2018, 5:54 PM

#

@trail shale on guns I just snap the hand mesh to a gun socket while it’s gripped then on release it goes back to the original location

#

If you have a master grippable with the logic all you need to do is update the relative vector and hand anim for each item and that goes pretty quick

trail shale Dec 16, 2018, 6:31 PM

#

@glossy agate Thanks - I'm using an interface for grabbing and I have event ticks on each one but I think I could probably keep it on a master grab with the logic, that makes sense. I was getting thrown off by trying to attach the item to the controller or vice versa, using SetAttach, but it seems to be easier and probably more performant, to just hide the motion controller itself and toggle visibility of a hand mesh gripping said object (otherwise the movement of the MC while holding the item was confusing and constraining the motion controller proved difficult)

What is the best practice for clamping the movement based on the scale of the object (so you can't pull a valve further than it's length, and probably a little less) ..... I want it to be relative but the implementation of GetRelativeScale of the static mesh is proving unclear.

#

Right now, without the clamp, the movement implementation is the single SetWorldLocation pulling 3 inputs from two actor worldloc variables, so it is nice and simple

#

I'd like to use a constraint for the size that is relative so if I resize the object the logic still works

sonic lake Dec 16, 2018, 7:27 PM

#

@trail shale For VR interactables like drawers, levers etc. I would stay away from the idea of attaching them to the MC and use a MC tracking method instead. That makes it easier to set limits/constraints and respect them because each interactable actor is responsible for its own behavior.

trail shale Dec 16, 2018, 7:56 PM

#

@sonic lake Yes that seems to be the best way; ca you tell me what is the best way to get the size of an object so I can clamp the axis so you can't effectively pull a valve out of a socket???

sonic lake Dec 16, 2018, 9:08 PM

#

@trail shale You don't need to know the size. You can use something like two arrows inside your interactable actor to set the max and min limit, but that depends on exactly what you want to implement.

#

I saw a good tutorial some time ago about implementing an interactable button. I think it would fit to what you are trying to achieve, let me look it up.

What's the best way people have used 2d UIs in vr? My only idea is to spawn it infront of the headset, and attach it to the root component so you can move around it in world space.
Should I be rethinking UIs completely for vr? Instead of doing a flat 2d ui, rendering things in 3d and attaching to world space?

@mighty carbon does it break that often when you stick to the oculus branch?

nope,

I was using it before to take it's X location when it is grabbing a valve and use that to set the location of the valve itself...worked great but wasn't a relative solution, so if you rotate the actor, it breaks

So I'm trying to convert the hand's world position to a relative one but am having issues

@mighty carbon

mighty carbon Dec 17, 2018, 8:07 PM

@sturdy coral apparently it also breaks for stock launcher for folks working with Google VR too (4.21.1 at least)

but yes, every release there is a major issue with mobile VR (but this is first time I think when it outright breaks no matter what options are used in the project settings)

Unity has issues too, but they aren't show stoppers usually

(because Oculus makes sure Unity works)

@trail shale compose transforms is probably what you want, compose hand's world transform with valve actor's world transform

#

can't remember the order, but I'm pretty sure the compose transform node's documentation has it backwards

#

that should give you back a transform relative to the valve, same thing you would get if you attached the motion controller to the valve and told it to keep it's world location instead of snap to location, and then queried relative location.

#

been using AMD for too long t-t

#

do I need to restart the WMR app to notice a difference?

sturdy coral Dec 17, 2018, 11:52 PM

#

@last sky you may want to do a full reboot

#

I'm not sure you are seeing the same thing though

last sky Dec 17, 2018, 11:53 PM

#

wait hang on, this is just the display settings for my monitors not the headset

sturdy coral Dec 17, 2018, 11:53 PM

#

but for me, once I started WMR my main monitor with a black background would flicker and become brighter

#

yeah I'm not sure if it has any effect on the HMD but it might

last sky Dec 17, 2018, 11:53 PM

#

oooh this is a fix for the monitors

sturdy coral Dec 17, 2018, 11:53 PM

#

it used to on oculus with DK2

#

somehow it would apply to both

last sky Dec 17, 2018, 11:53 PM

#

yeah no I haven't encountered that, but I suppose its good to have on as a precaution

#

I'll try restarting though

sturdy coral Dec 17, 2018, 11:56 PM

#

@last sky you'll need some other stuff to gett joysticks working, I think someone has a pull request for it

last sky Dec 17, 2018, 11:57 PM

#

yeah I did notice that

#

@sturdy coral so is the intention of even UE4.18 that you just use SteamVR and then that is supposed to make your app compatable with Oculus, Vive, Windows MR without requiring additional setup?

#

I just want to make sure that we're not missing something (beyond different controller input ofc)

last sky Dec 18, 2018, 1:07 AM

#

@sturdy coral hmm, I tried pulling your fix but that only seemed to make things worse. now when I roll my head it looks like the screen is being stretched out and compressed

#

this is in VR preview of the editor though

last sky Dec 18, 2018, 1:28 AM

#

sorry my bad, it seems like it was doing this before as well so your fix didn't affect the initial issue

sturdy coral Dec 18, 2018, 4:33 AM

#

@last sky hmm, not sure why it didn't fix it for you

#

I do remember that the VR editor (not VR preview) would still have the issue even after my patch and I never bothered figuring out why because 4.19 came out and fixed it all

#

I had this change too, but I think it maybe only improved things for Oculus and not WMR:

@sturdy coral all good, I realised that I didn't rebuild my engine properly. thanks for all your help, one of our team members is going to rebuild our source with either your hotfix or one from unreal engine itself

#

at least now I know that it has nothing to do with our app, because I encountered the same problem with the VR template level on 4.18.3

#

and on 4.20.3 it was fine

sturdy coral Dec 18, 2018, 4:37 AM

#

without that last change I think Oculus will use a vive-like aspect ratio, even though oculus provides a recommended target with a different aspect ratio than screen ratio

#

(probably the lenses stretch things more in one direction)

last sky Dec 18, 2018, 4:38 AM

#

thanks, we'll keep that in mind if we run into any issues with rift

sturdy coral Dec 18, 2018, 4:38 AM

#

everything will still look ok though without it, I think just the pixel allocation won't be ideal

last sky Dec 18, 2018, 4:39 AM

#

yeah WMR is the only device we've encountered that's been messed up

sly elk Dec 18, 2018, 1:37 PM

#

Does "bUseDesktopResolution=true" work in current unreal builds? Is this still the correct way to make sure fullscreen runs native res?

robust orbit Dec 18, 2018, 2:07 PM

#

has anyone else seen assertions in 4.21 for "InOutSizeX != 0 && InOutSizeY != 0" in CalculateRenderTargetSize on Oculus Go?

#

For some reason, the Oculus SDK is returning a zero eye viewport rectangle size for me.

gleaming river Dec 18, 2018, 2:10 PM

Hey all, has anyone noticed that with the wireless VR adapter, unreal games will crash after 120 seconds of being still

mighty carbon Dec 18, 2018, 2:14 PM

#

@robust orbit I can't even run 4.21.1 project on Go - inta crash

#

(same project built with 4.19 runs fine)

robust orbit Dec 18, 2018, 2:35 PM

#

@mighty carbon what's your crash callstack?

#

same for us... works on 4.19

mighty carbon Dec 18, 2018, 2:55 PM

#

@robust orbit https://github.com/Oculus-VR/UnrealEngine/issues/24

#

I already submitted bug report to Epic and Oculus and heard nothing back..

#

same as yours ?

fleet plume Dec 18, 2018, 3:26 PM

#

which is funny, because they're supposedly working on robo recall for quest

mighty carbon Dec 18, 2018, 3:27 PM

#

well, they have some private private branch of UE4 most likely

#

or maybe they even ported RR to Unity, for better performance

fleet plume Dec 18, 2018, 3:27 PM

#

lol

#

you don't believe that, right?

mighty carbon Dec 18, 2018, 3:28 PM

#

Carmack loves Unity a way more than UE4, so I wouldn't doubt such turn of events

fleet plume Dec 18, 2018, 3:28 PM

#

carmack isn't the epic owner

mighty carbon Dec 18, 2018, 3:28 PM

#

he hasn't touched UE4 with a long stick

robust orbit Dec 18, 2018, 3:29 PM

#

@mighty carbon you have a number of exceptions in the log, but I don't see a crash callstack. you might have attached the wrong long file.

mighty carbon Dec 18, 2018, 3:29 PM

#

Carmack is CTO of Oculus and basically the one who can call shots for mobile VR division

#

on top of that Oculus bought out everything RR related from Epic

fleet plume Dec 18, 2018, 3:29 PM

#

we'll see, but my money is on RR still being made in ue4

#

😛

mighty carbon Dec 18, 2018, 3:32 PM

#

yep, wrong f'ing log

#

ah, no, it's the right one

robust orbit Dec 18, 2018, 3:37 PM

#

ah, Google Docs preview cut off the file

mighty carbon Dec 18, 2018, 3:38 PM

#

yeh, it did

#

for a moment I thought I submitted a completely useless log to Epic and Oculus 😛

robust orbit Dec 18, 2018, 3:38 PM

#

your crash is different

mighty carbon Dec 18, 2018, 3:54 PM

#

btw @fleet plume there is a chance that Oculus started working on RR for Quest a way before 4.20 and thus they don't really care at this moment about issues in 4.21

#

hmm.. Epic just got back with me and said they built my project and had it running on Go without any crash (although they used launcher version and didn't use "adb install"; instead they used Launch on the Device option).

#

I am gonna have to try that

fleet plume Dec 18, 2018, 4:28 PM

#

@mighty carbon that sounds more likely than porting it to unity 😛

tired tree Dec 18, 2018, 5:50 PM

#

@fleet plume considering that oculus internally uses UE4...even more so

mighty carbon Dec 18, 2018, 5:53 PM

#

but they only use it for Rift projects

#

anything mobile is powered by Unity

tired tree Dec 18, 2018, 6:02 PM

#

then wouldn't it be in their best interest to port it using UE4 to make sure it is up to snuff with their new hardware? 🙄

mighty carbon Dec 18, 2018, 6:03 PM

#

it would be in our best interest 😃

wicked oak Dec 18, 2018, 6:18 PM

#

@mighty carbon oculus has implemented a bunch of good shit for mobile vr

#

they did all the work for monoscoping render and multiview mobile

mighty carbon Dec 18, 2018, 6:19 PM

#

yeah yeah.. and a lot of people have a ton of issues with 4.21..

#

they sure did the work, but to make it work 100% from release to release is whole different story

flat shoal Dec 18, 2018, 6:55 PM

#

does oculus exist anymore? I've seen them being referd to as "facebook vr"

sly elk Dec 18, 2018, 7:09 PM

#

I posted this in blueprint chat but someone here might know as well

#

My package builds are running a fixed resolution in fullscreen mode (that is smaller than native). I gather bUseDesktopResolution=True is what I want but It doesn't do anything when added to my packaged builds. Where do I need to set it?

sturdy canyon Dec 18, 2018, 7:22 PM

#

In VR you use a different setting for resolution

#

It's vr.pixeldensity, I think?

sly elk Dec 18, 2018, 7:30 PM

#

my game is both VR and desktop

#

this is for the desktop launch mode

#

game looks like this on 2d mode launch: https://i.imgur.com/hKymZ06.png

Imgur

#

on my 4k display

#

alt enter to get to windows

#

and the windows up key to make it big, its clearly just resizing the same res

frigid kite Dec 18, 2018, 7:39 PM

#

Maybe you can get around bUseDesktopResolution not working by manually setting the resolution to the max allowed resolution of the monitor?

sly elk Dec 18, 2018, 7:43 PM

#

yeah, i supposed that is hte best solution

dusky moon Dec 18, 2018, 8:49 PM

Guys I'm getting this really weird editor crash on 95% when I load my project. It's something with OculusSpatializedAudio and somehow when I enable "Mirror Audio" on my Oculus plugged-in the crash goes away! does it sound familiar to any1 here ?!

sturdy coral Dec 19, 2018, 12:43 AM

#

@sly elk GameUserSettings has some stuff around fullscreen/windowed

#

so when you resize, it is scaling the pixels instead of using more pixels?

sly elk Dec 19, 2018, 12:49 AM

#

Thanks. finally fixed it. Jim's computer had some old config files getting used in the build

#

prevent those settings from working

mighty carbon Dec 19, 2018, 2:04 AM

#

I have an interesting development - if I use stock launcher and instead packaging the game and manually installing it using adb, I do Launch on the Device from the Editor - the game runs

#

I am going to try to do the same with Oculus fork

fleet plume Dec 19, 2018, 10:34 AM

#

@mighty carbon does it still not crash when you start the game from within the Go after the first "Launch on device"?

mighty carbon Dec 19, 2018, 12:09 PM

#

@fleet plume not when using launcher version of UE4

fleet plume Dec 19, 2018, 12:11 PM

#

too many not's

#

so does it work for you when you launch on device? also on subsequent starts from within Go Home?

mighty carbon Dec 19, 2018, 12:14 PM

#

It runs when I use 4.21.1 launcher version and Launch on the Device button

#

I didn't try launching the game from Home after that

#

But I tried building as usual and installing manually - crashing

#

Is that clear enough? 😅

fleet plume Dec 19, 2018, 12:17 PM

#

yes

#

i wonder if the manifest etc is different

#

afaik at the end of the day in both cases an .apk gets deployed on the device
