@mighty carbon are you on an ssd?

mighty carbon Oct 7, 2018, 3:41 AM

#

nah, 7200 rpm HDD

sturdy coral Oct 7, 2018, 3:52 AM

#

that should be your next purchase, they help build times a lot though I think 5hrs might have something else wrong

mighty carbon Oct 7, 2018, 4:05 AM

#

hmm.. what else could be wrong @sturdy coral ?

sturdy coral Oct 7, 2018, 4:08 AM

#

@mighty carbon that was all for development editor, or for building everything, shipping etc.?

mighty carbon Oct 7, 2018, 4:12 AM

#

I chose Dev Editor and did Build Solution

#

Win/Android environment, Oculus fork

dusky moon Oct 7, 2018, 8:13 AM

#

So is everybody ok here with the new oculus update ?! all my projects got a huge performance hit (almost doubled framerate) I think it's because of the dash overlay...

sonic lake Oct 7, 2018, 10:42 AM

#

@dusky moon did you also update the graphic drivers? I am having some regressions with the latest NVidia versions.

dusky moon Oct 7, 2018, 12:01 PM

#

@sonic lake first with the older driver (39x or something) it was laggy. then I updated to the latest and its still crap

#

I sent a support ticket

sonic lake Oct 7, 2018, 12:05 PM

#

What if you kill OculusClient.exe completely?

dusky moon Oct 7, 2018, 12:26 PM

#

it brings back the home and dash automatically. I tried to set it to run as administrator to avoid it. and then when I hit VR Preview when the OculusClient is closed headset is just black and doesnt load anything

sonic lake Oct 7, 2018, 12:33 PM

#

Strange. It should work regardless. Even after a reboot?

sonic lake Oct 7, 2018, 1:17 PM

#

Anyway it is just for test purposes because your users will have the Oculus Client running.

dusky moon Oct 7, 2018, 2:35 PM

#

Nah no chance after reboot. I bet the rift core is not optimized though and should be fixed from oculus' side

quiet swan Oct 7, 2018, 3:15 PM

#

what are you all using for an inventory system in unreal?

#

for vr?

#

did any of you buy a regular invenotry system and tweak it for VR????\

sage gulch Oct 7, 2018, 5:11 PM

#

on my system the driver seems to accumulate an error and after a day or two requires a reset, otherwise the tracking resets itself constantly as if the rift or camera was being unplugged.. did that on 1.5, still does on 2

wicked oak Oct 7, 2018, 5:40 PM

#

lmao i can go to pixel density 5 on DWVR on the new 2080

#

overkill much

#

im going to see if i can get it to run on my galaxy 8, as a test for the Quest

#

at least half-run the chaos benchmark i have

sturdy coral Oct 7, 2018, 7:08 PM

#

@wicked oak maybe you can expand FOV way beyond the HMD, and then get SSR without edge artifacts

mighty carbon Oct 7, 2018, 8:28 PM

#

so, finally tried new Oculus Home and I really liked it. Literally sat there for some time looking at the opening in my cave to the wonderful wilderness outside.

sage gulch Oct 7, 2018, 9:23 PM

#

it's pretty cool

sly elk Oct 8, 2018, 1:34 PM

#

Hey all, im implementing smooth locomotion today. Copying what onward does, is that the gold standard/what users expect?

#

also, should thumbstick just get input direction or should I scale the movement speed to the amount of thumbstick pull?

jaunty shell Oct 8, 2018, 1:35 PM

#

gold standard is full 1:1 movement 😄

#

some people prefer smooth, some prefer teleportation

sly elk Oct 8, 2018, 1:35 PM

#

yeah, we have teleportation

#

just adding a smooth locomotion option

#

i hate smooth locomotion since it makes me sick so I'm not sure what people want

jaunty shell Oct 8, 2018, 1:36 PM

#

some people might whine about Wrench not having it

#

about the accceleration thing

sly elk Oct 8, 2018, 1:36 PM

#

wanting multiple speeds?

jaunty shell Oct 8, 2018, 1:36 PM

#

wait

#

"some people might whine about Wrench not having it" meant for smooth loco

sly elk Oct 8, 2018, 1:37 PM

#

yeah, thats why we are adding it as an option

jaunty shell Oct 8, 2018, 1:37 PM

#

accel thing, how is onward working ? There's multiple speeds ?

sly elk Oct 8, 2018, 1:37 PM

#

i htink its going to be a toggle on thumbstick click

jaunty shell Oct 8, 2018, 1:37 PM

#

I've always found out that some people have difficulties with acceleration in VR

#

but yeah, stick position to speed sounds decent

#

better yet

#

go for an armswing loco 😂

sonic lake Oct 8, 2018, 1:46 PM

#

@sly elk It should be immediate acceleration at the final speed, with a settings option to choose your speed of movement. And snap rotation for turning. You can use 45 or 90 degrees as basis and make the angle configurable in settings. This is what is less likely to trigger cyber-sickness in our experience.

jaunty shell Oct 8, 2018, 1:48 PM

#

yeah snap turn is important too, some people get sick really fast with smooth rotation

sonic lake Oct 8, 2018, 1:50 PM

#

Any type of acceleration, both linear and angular, has to be avoided because VR stimulates only the ocular system, not the vestibular one, so any acceleration creates an oculo-vestibular mismatch which leads to cyber-sickness.

jaunty shell Oct 8, 2018, 1:50 PM

#

yup

sly elk Oct 8, 2018, 1:50 PM

#

so thats different than onwards implementation (the snap turning) right? In onward the left and right to strafing

#

*do strading

jaunty shell Oct 8, 2018, 1:51 PM

#

had some good laugh during the DK1 era with people trying to compensate for virtual motion with their body

sonic lake Oct 8, 2018, 1:52 PM

#

Strafing could be just lateral linear motion.

#

But you keep facing the same direction.

sly elk Oct 8, 2018, 1:55 PM

#

So i guess one other requirement is that all locomotion needs to happen with just a single thumbstick

#

everything in wrench is fully ambidextrous and the A/B buttons are in use for other stuff

sonic lake Oct 8, 2018, 1:56 PM

#

That's tricky because usually one thumbstick is linear motion and the other one is turning.

sly elk Oct 8, 2018, 1:57 PM

#

Yeah. We don't need our movement to be as robust as something like a shooter though

#

nothing is fast paced

#

never at risk of player death

sonic lake Oct 8, 2018, 1:59 PM

#

Yes but if you want a granular coverage of the virtual play space you have to allow for both linear movement and rotation at the same time. Unless rotation is secondary then you can think of switching to it only if needed.

#

Say that you want to go around the engine while you are assembling it. You will do left, left, forward, forward, 180 rotation, left, left

#

Or left, left, 90, left left, 90, left left

sly elk Oct 8, 2018, 2:01 PM

#

yeah. I guess it will be worth breaking our symmetrical controller input rule for smooth loco

sonic lake Oct 8, 2018, 2:02 PM

#

I think so too

#

Unless you move around things on a predefined path, always facing them. Not sure that works for the dynamic of your game.

sly elk Oct 8, 2018, 2:03 PM

#

Nah, it needs free exploration

sonic lake Oct 8, 2018, 2:03 PM

#

Then you need 3 DOF, 2 linear and 1 rotational

#

An alternative way to do rotation could be, for example, pressing both grips at the same time, like to grab an invisible round handle in front of you, and then swinging your hands either to the right or to the left. You let go to end the rotation. Can be tricky if you want to move while carrying something to take it with you.

tired tree Oct 8, 2018, 2:23 PM

#

snap turn makes more sense in Wrench than smooth turn

#

there isn't much of a reason to care about the intermediate rotations

mighty carbon Oct 8, 2018, 2:23 PM

#

snap turning is a good turning - I've tried it several times in various VR projects and it didn't make me sick.

sonic lake Oct 8, 2018, 2:28 PM

#

Totally agree, this was the first indication anyway. As long as you let the people configure the snap turn angle. Some may want a more granular turn (say 15 or 30 deg) some others may be ok with just 45 or even 90 deg.

tired tree Oct 8, 2018, 2:28 PM

#

just make sure you blink the screen

#

some people prefer smooth turn because the instant snap disorientates them

#

but fading/blinking the screen removes that

#

should be able to get away with just snap then

mighty carbon Oct 8, 2018, 2:35 PM

#

Hmm.. Not even Oculus Home 2.0 has blinking screen

#

(unless I just didn't notice it)

sonic lake Oct 8, 2018, 2:42 PM

#

Our tests show that "blinking the screen" is necessary only if the new view has no visual reference whatsoever to the previous one (e.g. snap rotation of 180 degrees or teleportation to a far location). This has the effect to "reset" your sense of presence so that your brain is forced to rebuild it from scratch. Otherwise users are just fine with an immediate transition to the new view. At the end it boils down to personal preferences though, which would call for yet another configurable option.

wicked oak Oct 8, 2018, 2:43 PM

#

i reeally like what skyrim or others do

#

"blink" rotation is actually smooth rotation to a target

#

but very fast

#

and optional blurring/blinders

sonic lake Oct 8, 2018, 2:47 PM

#

Blurring is interesting because it simulates the momentary shutdown of eye focus and use of peripheral vision only that happens when we turn out head very quickly IRL.

#

On the other hand I find the "tunnel vision" effect which is, for example, in Google Earth VR very sickening.

tired tree Oct 8, 2018, 3:05 PM

#

if its only 45 yeah its fine

#

mostly

#

but there are always outliers

#

and fading / blinking can be near instant

sly elk Oct 8, 2018, 3:58 PM

#

so for snap rotatation. Flash white briefly between states?

mighty carbon Oct 8, 2018, 4:05 PM

#

black

sly elk Oct 8, 2018, 4:21 PM

#

So smooth movement is at 50cm/s with a settings option to multiply that up and down. Thumbstick click toggles between smooth locomotion and teleport.

Does anyone know if MBFR works on console as well?

trail shale Oct 8, 2018, 5:14 PM

#

Is there a debug mode to show headset view frustams? I'm trying to make binoculars and it would be a lot easier to get an idea of what I am looking at

📎 unknown.png

daring mural Oct 8, 2018, 6:11 PM

#

@trail shale I think one of the HMD view modes gives you a stereo output that shows both eyes. I'm not sure how to get it working, @charred portal has his projecting like this in his packaged game, I believe

deft moat Oct 8, 2018, 7:42 PM

#

Hey @trail shale, I offered some pretty bad advice the other day, and this might be more of the same, but the packing peanut shape makes sense when you're wanting to give the illusion of binoculars in a non-VR setting. Since binoculars have you looking through two separate lenses, and VR is the same, would it make sense to just have a single circle that each eye looks through?

trail shale Oct 8, 2018, 7:52 PM

#

I had some help but figured out that if you spawn a plane with the 2d texture on it, with the right settings it works

#

you even get the binocular distortion if you spawn it too close

#

I have an overlay I use but you can't see it, which makes sense, because the HMD itself has a physical "overlay" e.g. the holes you actually look through

quiet swan Oct 8, 2018, 8:07 PM

#

I have a strange issue I am using the VRE plugin with 4.20 and notice now if I use the FPS test pawn or simulate my game lags at 4 fps but if I play in VR mode it plays normal

#

why is my game lagging in only select view port and simulate???

sturdy coral Oct 8, 2018, 11:21 PM

#

is the new oculus wrist watch going to interfere with games that use wrist watches? =/

#

it shows up even when dash isn't open right?

sturdy coral Oct 8, 2018, 11:40 PM

#

ah looks like only if the watch is pinned, and only if app is submitting depth to support dash

sage gulch Oct 8, 2018, 11:53 PM

#

yeah so what is the deal with that, I have a friend with a custom engine and when you bring up dash it will only show the icon panel.. but if you pull a window out of oculus desktop, it will properly integrate that into z-space even when dash is closed

#

any pointers on docs?

sturdy coral Oct 9, 2018, 12:57 AM

#

not sure, but I think ue4 or at least the oculus branch of it has done an integration

#

openvr/steamvr has added zbuffer support in recent versions but I don't think it has been integrated yet in ue4

#

(even if they are on a high enough version of the lib, I don't think they are submitting the buffers)

tired tree Oct 9, 2018, 1:20 AM

oculus has had depth support for stereo layers for awhile

slim karma Oct 9, 2018, 12:14 PM

#

what would be a good mirror mode to check on screen messages from a print sting node? looks like in the default one it's not on the screen

sonic lake Oct 9, 2018, 12:40 PM

#

@slim karma Depending on what your are trying to diagnose, a common technique is to add a debug Text Render Component to your motion controller and set its text value to whatever your want to monitor. Then you can just look at it.

slim karma Oct 9, 2018, 12:42 PM

#

well I just wanted to display a few vector coordinates to the screen to check if they're what I'm expecting. But I'll take a look at you suggestion, sounds very helpful indeed! 😄

You can also use DrawDebugLine to visually plot your vector and see it change over time. https://api.unrealengine.com/INT/BlueprintAPI/Rendering/Debug/DrawDebugLine/index.html

its not like you are re-writing the hmds sdk

#

they also have a full reference implementation in ue4

#

it may be missing some things that 4 has, like instanced stereo but they also don't have to keep things as generic as the full engine does

https://venturebeat.com/2018/10/07/oculus-quest-tracking-is-indoor-only/

From what I've read of the article and various others, is that it's not 'meant' for outdoor use, even though they've already added an automatic dimming feature for the cameras. That it's mostly due to the fact that it's easier to track indoors, not to mention lots of legal stuff and the like. Though it will have difficulty tracking in extremely bright or dark areas, so that's a factor to add in.

So I think going to a football stadium and using it is a bit far fetched, but going to your back yard and maybe drawing a few chalk lines might actually be plausible for an extra large play space if it's either slightly cloudy or even an overcast day.

Can I have 3d images rendered in vr? Left side only visible in left eye, right side in right eye?

mighty carbon Oct 9, 2018, 8:37 PM

#

I believe you could @real needle

sonic lake Oct 9, 2018, 10:07 PM

#

@soft beacon check the component hierarchy of your pawn. The VR Camera should be parented to a VR Origin Scene Component which typically is parented to the root component. As the pawn moves, the camera moves along because the VR Origin moves with the root.

#

@real needle you have to create a stereo material for that. That allows you to project a different texture for each eye.

New Asynchronous Spacewarp 2.0 will help VR run better on Rift across all hardware. Using PTW and depth from the app, it addresses the motion estimation artifacts of ASW around rapid brightness changes, rapid head movement with repeating patterns and contradictory movement...

oh so that's actually a "feature" of the rift. I always hated that everything gets torn to shreds on my screen.

#

nice to see that it gets fixed

sonic lake Oct 10, 2018, 11:10 AM

#

NOTE to anyone running own (unknown sources) applications on the Oculus platform having bypassed Oculus Home, be aware that the latest update, which is being pushed regardless of auto-update being turned OFF, breaks them. You will get a black screen in the Oculus unless you re-enable Oculus Home.

#

Honestly I am getting pretty angry at Oculus as this is the second time they do something like this. If auto-update is turned off, one should legitimately expect that no software change takes place unexpectedly.

#

Ok last time they blocked all their systems worldwide, so one my argue that this is a relatively minor screw-up.

head turning, not much issue

oculus inside out tracking is better tho

a lot better

motion controller is 6dof

but its laggy

it uses magnetic tracking, and its not fully accurate and it has massive latency

the controller itself is quite good tho, solid, and with a trackpad

Hi guys, I'm developing a simulation in Oculus GO. I've followed the standard process of pulling Oculus repository from their github, build the engine and use the samples they have provided. Although what the funny part is when I open there default Input map and run it in Oculus Go. I get this screenshot

#

Notice the fps coming on the default level

📎 com.YourCompany.PerformanceLevel-20181010-200040.jpg

#

This is crazy, I'm not touching even 40 fps. Is that default with the oculus Go or I have to change few things at my end ? I've just used the default settings of the Project Settings, with Forward Renderring enabled

@tired tree is this gonna impact you a lot again, like the 4.19 physics replication changes?

#

Physics Interface: We have been reworking the physics interface to support an increased ownership of physics objects at the high level. As a consequence much of the physics related c++ code an API has changed.

tired tree Oct 10, 2018, 3:07 PM

physics replication changes were aggravating because they were changed to support fortnite and required changes for my use because that caused issues outside of their use case

#

this api change is good overall, hasn't been that bad to convert to

sturdy coral Oct 10, 2018, 3:13 PM

seems CCDIK may not be using full physics asset constraints:

     /** symmetry rotation limit per joint. Index 0 matches with root bone and last index matches with tip bone. */
    UPROPERTY(EditAnywhere, EditFixedSize, Category = Solver)
    TArray<float> RotationLimitPerJoints;```

@tired tree any idea why they are emulating AActor::CalcCamera() here instead of just calling it? Doesn't that mean we can't override CalcCamera?

FTransform FXRTrackingSystemBase::ComputeTrackingToWorldTransform(FWorldContext& WorldContext) const
{
[...]

                const bool bUsesImplicitHMDPositioning = XRCamera.IsValid() ? XRCamera->GetUseImplicitHMDPosition() :
                    PlayerViewTarget && PlayerViewTarget->HasActiveCameraComponent();

                if (bUsesImplicitHMDPositioning)
                {
                    TArray<UCameraComponent*> CameraComponents;
                    PlayerViewTarget->GetComponents<UCameraComponent>(CameraComponents);

                    UCameraComponent* PlayerCamera = nullptr;
                    for (UCameraComponent* Cam : CameraComponents)
                    {
                        // emulates AActor::CalcCamera(); the PlayerCameraManager uses ViewTarget->CalcCamera() for
                        // the HMD view's basis (regardless of whether bLockToHmd is set), CalcCamera() just finds
                        // the first active cam component and chooses that
                        if (Cam->bIsActive)
                        {
                            PlayerCamera = Cam;
                            break;
                        }
                    }

#

End result I'm going for is having camera components with a "VR" tag get picked automatically in VR and not picked in 2D

#

ah looks like AActor::CalcCamera returns the view only

#

where this needs the component in order to get the parent

#

@sturdy coral you are welcome for the answer :p

sturdy coral Oct 10, 2018, 5:21 PM

#

it seems like a bad design=/

#

guess I'll just modify the engine code though but I hate diverging too much

#

hmm, and this seems like a bug:

#


bool AActor::HasActivePawnControlCameraComponent() const
{
    if (bFindCameraComponentWhenViewTarget)
    {
        // Look for the first active camera component and use that for the view
        for (const UActorComponent* Component : OwnedComponents)
        {
            const UCameraComponent* CameraComponent = Cast<const UCameraComponent>(Component);
            if (CameraComponent)
            {
                if (CameraComponent->bIsActive && CameraComponent->bUsePawnControlRotation)
                {
                    return true;
                }
            }
        }
    }
    return false;
}```

#

only used here:


    if (!PlayerCameraManager || !ViewTarget || !ViewTarget->HasActiveCameraComponent() || ViewTarget->HasActivePawnControlCameraComponent())
    {
        if (IsLocalPlayerController() && GEngine->XRSystem.IsValid() && GEngine->XRSystem->IsHeadTrackingAllowed())
        {
            auto XRCamera = GEngine->XRSystem->GetXRCamera();
            if (XRCamera.IsValid())
            {
                XRCamera->ApplyHMDRotation(this, ViewRotation);
            }
        }
    }```

#

if there are two active cameras, and the second one has IsHeadTrackingAllowed, it looks like the first camera will end up being treated as if it had IsHeadTrackingAllowed

Hi all. I'm trying to play mp4 video at start of the application on Oculus Go (splash screen) but when app starts video appearing from 1-2 second from it beginning. Some laggish. But in simulation mode it plays smoothly. Cache video checkbox didn't help. Video is media texture in unlit material placed on the plane. 720p 30 FPS

warm lion Oct 10, 2018, 7:24 PM

#

is there a way I can detect when the player puts the head set on? Right now when I launch to the Oculus Go, when I put the headset on I can tell that a timer has already started ticking. I need to delay this for my testing purposes even if it's not for final.

There should be an isworn? Boolean or something similar to it

getHMDWornState thanks!

Hmm, so that seems like it is still missing some time. The only thing I can figure is that the calibration screen still counts as "worn" but the timer is already starting

The screen you have to do whenever you put the headset on from a inactive state

Having a difficult time with my physics handle using motion controllers. I send out a trace using the forward vector of my motion controller, and then determine the distance between my motion controller and impact point on the hit object. On Event Tick, the physics handle location is updated to the motion controller's forward vector multiplied by the offset calculated after the trace is sent out. But for some reason, my held component immediately behaves strangely and veers off to the right. Am I doing something weird here?

📎 EventTick.PNG

sturdy coral Oct 10, 2018, 9:49 PM

#

have you set up tick dependencies?

deft moat Oct 10, 2018, 9:49 PM

Sorry, one picture didn't post... Discord thought I was being explicit? One moment

#

Clyde's really getting me down here. It doesn't like an image named "blueprint"

#

Sorry, tick dependencies? No

sturdy coral Oct 10, 2018, 9:52 PM

#

I'm not sure it is an issue here, but the motion controller's tracked location isn't updated until it ticks

#

you can still get partial movements due to relative attachment before it ticks though

#

if the root is moving, and if the thing moving it ticks first

#

depending on when you are tracing that might be your issue, the trace could get a little farther away every time

#

unless you just do a single trace

deft moat Oct 10, 2018, 9:54 PM

#

Will it keep cycling through an input action until I release? Or just cycle once until the button is pressed again?

sturdy coral Oct 10, 2018, 9:55 PM

#

it should just trigger it once, I think there are some settings around key repeat that could apply but shouldn't by default

deft moat Oct 10, 2018, 9:56 PM

#

📎 Capture.JPG

#

There we go. That's how I set the offset float. Which doesn't update in my tick function. What's strange is that I'll still be holding the component, it's just that it shoots off toward the right initially. It still responds to movement by the motion controller, just offset by 100 units or so

sturdy coral Oct 10, 2018, 9:59 PM

#

@deft moat how does the rotator work on that grab func?

#

and is the object origin somewhere that if it were rotated it could move by 100 units. or is it centered pretty well

deft moat Oct 10, 2018, 10:01 PM

#

The object is just a cube with the origin in the center. But since I'm grabbing the object at the location of impact, it shouldn't move at all, right?

sturdy coral Oct 10, 2018, 10:03 PM

#

I don't know, the documentation on that node isn't clear, I'm sure there is a full explanation of it somewhere else though

deft moat Oct 10, 2018, 10:13 PM

#

Adjusting the rotator value doesn't do anything. But using the grab component at location only (not rotation) function causes the held component to be able to spin freely around the grabbed location.

My problem seems to be whatever is happening after Event Tick, but I can't wrap my head around why.

#

Eff. I know my problem. In Event tick, it's updating the physics handle location to my forward vector * my offset float, but from 0,0,0, not my motion controller location

sonic lake Oct 11, 2018, 5:14 PM

Yes. That's pretty much it. I am making noise on the forums (Oculus / Reddit) to let them understand that this is not how you deal with updates.

#

Plus had yesterday all our customers that were connected to the internet complain at once that their system was no longer working. No fun.

I think Oculus wanted to deliver some of their promises after the OC5 and the update was so rushed and broken

#

my ticket for the performance hit with UE4 is still open after 3 days of sending logs and stuff

#

just to note how shit the mandatory home load is... when you put the headset above your forehead to change something in UE, the home loads up.... it almost takes 700 MB of Ram at some points

sonic lake Oct 11, 2018, 5:31 PM

Exactly. That was the other advantage of being able to disable home. It is super annoying while you are developing.

@dusky moon Pretty much everything is explained here: https://developer.oculus.com/documentation/unreal/latest/concepts/unreal-dash/

#

Also I would not use Event Tick for the check, but set a timer on a longer time span than 1 tick

dusky moon Oct 12, 2018, 7:41 PM

#

@sonic lake yeah I did try Event by Timer on loops with 1 sec interval ... but still the problem is it pauses the game when I first hit the home button. but then if I hit it again to resume ,it remains paused no matter how much I press it afterwards

sturdy coral Oct 12, 2018, 8:10 PM

@median wedge it is already implemented with the Facebutton events

hi all, anyone know how to set spectator window for VR to render right eye instead of left?

sturdy coral Oct 12, 2018, 8:13 PM

#

@limber rose adding .5 to the UVs should do it

#

I don't know if there is a setting

limber rose Oct 12, 2018, 8:14 PM

#

haven't ever really messed with the spectator viewport except for basic "spectatormode" setting

sturdy coral Oct 12, 2018, 8:14 PM

#

@dusky moon tick doesn't happen when paused

limber rose Oct 12, 2018, 8:14 PM

#

change the UVs on the texture of the renderer?

sturdy coral Oct 12, 2018, 8:14 PM

#

you need to do it on an actor with allow tick when paused

#

@limber rose


void FDefaultSpectatorScreenController::RenderSpectatorModeSingleEye(FRHICommandListImmediate& RHICmdList, FTexture2DRHIRef TargetTexture, FTexture2DRHIRef EyeTexture, FTexture2DRHIRef OtherTexture, FVector2D WindowSize)
{
    const FIntRect SrcRect(0, 0, EyeTexture->GetSizeX() / 2, EyeTexture->GetSizeY());
    const FIntRect DstRect(0, 0, TargetTexture->GetSizeX(), TargetTexture->GetSizeY());

    HMDDevice->CopyTexture_RenderThread(RHICmdList, EyeTexture, SrcRect, TargetTexture, DstRect, false);
}```

#

add .5 to each of the SrcRect x coords

#

-     const FIntRect SrcRect(0, 0, EyeTexture->GetSizeX() / 2, EyeTexture->GetSizeY());
+     const FIntRect SrcRect(0.5f, 0, 0.5f+(EyeTexture->GetSizeX() )/ 2, EyeTexture->GetSizeY());

limber rose Oct 12, 2018, 8:17 PM

#

ah super helpful, thank you

sturdy coral Oct 12, 2018, 8:18 PM

#

@limber rose if you are doing it for scopes you may want to add a new mode that lets your choose right/left

#

and pick it based on hand the gun is in

#

but then again I think some people are left eye dominate and right handed and every other permutation

limber rose Oct 12, 2018, 8:19 PM

#

exactly right

#

yup

#

mind reader you are 😉

median wedge Oct 12, 2018, 8:23 PM

#

Thanks, and does anyone know of a way to render where the finger currently is on the touchpad, I have seen some games do this

dusky moon Oct 12, 2018, 8:30 PM

#

@sturdy coral ooo there we go! thanks a lot man phew

sturdy coral Oct 12, 2018, 8:31 PM

#

np

#

@median wedge the steamvr render components /transforms api gives you a little indicator component I think

sage gulch Oct 12, 2018, 8:32 PM

#

use the keyword capacitive in the autocomplete/suggestion box in blueprints

sturdy coral Oct 12, 2018, 8:32 PM

#

but ue4's render model support isn't animated so it doesn't show up

#

you could manually read in the transform through the plugin

#

or just hard code it

median wedge Oct 12, 2018, 8:33 PM

#

Ok. Thank you

sonic lake Oct 12, 2018, 8:56 PM

#

@dusky moon Sorry, but I saw you got your answer from @sturdy coral in the meantime

#

One thing to note. If you want to make your application dash aware using the command line parameter -oculus-focus-aware note that it has to be -oculus-focus-aware true.

#

The official documentation doesn't mention you need to specify true

dusky moon Oct 12, 2018, 8:59 PM

#

np, yes I enabled it through Engine.ini though and works. Thank you!

Anyone had any success with implementing a BT keyboard for debugging purposes? I was able to pair one to the Oculus Go, through the phone app. Only the esc key seems to work. I know it's not officially supported but I've heard that it can be implemented at the app level. Any ideas how one would go about that?

sage gulch Oct 14, 2018, 3:38 AM

You'd probably need to go lower level than UE I would think,.. UE doesn't really support system level drivers AFAIK

NOOB question.
I package my project for windows 64 bit, with no errors. But VR not working (Oculus) when executed.
Oculus works perfect inside unreal engine VR preview. What am I missing ?

sonic lake Oct 15, 2018, 9:49 AM

#

You need to check the Start in VR flag in the project settings

#

Or launch the exe with -vr

#

^^^ @dusty dagger

dusty dagger Oct 15, 2018, 9:50 AM

#

thanks VR_marco.
I'll try that

It worked, thank you so much..

sonic lake Oct 15, 2018, 9:59 AM

#

You are welcome

fresh wharf Oct 15, 2018, 11:44 AM

#

does anyone know how you could launch your project upon booting up the oculus go?

sonic lake Oct 15, 2018, 12:13 PM

#

There is no kiosk mode available on the Oculus Go. There have been workarounds, but all the latest updates have broken them.

#

IMHO, Oculus has no interest in supporting a kiosk mode because their business model is selling the hardware in order to sell the VR experiences through their embedded online store. Kiosk mode means no store.

#

Unfortunately they seem to be following the same practice with the latest release of the Oculus Rift core, where they took away the possibility to use the HMD with any other VR experience if the Oculus Client (including the online store) is not running.

fresh wharf Oct 15, 2018, 12:29 PM

#

@sonic lake unlucky that there is no kiosk mode available, thanks for the info though

im also trying to set up the native mobile sdk so that i can make an app for the oculus go, what ide would be best to use? fairly new to this. I can't use unreal or unity because i want the app to load in pictures and videos from internal storage.

sonic lake Oct 15, 2018, 12:30 PM

#

I never looked into it but I believe you can read from the internal storage using UE4

#

I assume that would be like reading from the file system

fresh wharf Oct 15, 2018, 12:31 PM

#

i could get it to read and display it inside the running unreal project

#

but the problem is that it was too heavy

#

and unreal would crash

#

it does run when you open it from gallery though

#

i have to make it so that people wont have to navigate through the gallery to open a video or picture

#

but that they can just put the go on and select what picture/video they want to see

sonic lake Oct 15, 2018, 12:34 PM

#

I develop for the Go but I never looked into displaying images/videos from the gallery. BTW, where would they come from? The Go doesn't have a camera.

fresh wharf Oct 15, 2018, 12:35 PM

#

just 360 degree pictures and videos taken inside a running ue4 project

#

i could just put them into the pictures folder on the Go

#

but then it's a hassle for people to open them

sonic lake Oct 15, 2018, 12:35 PM

#

and the project runs on the same Go?

fresh wharf Oct 15, 2018, 12:36 PM

#

nop

#

project crashes

#

cause it's too heavy for the go to handle

#

i made a video with Nvidia Ansel which i dumped in the internal storage of the Go

sonic lake Oct 15, 2018, 12:37 PM

#

Ah ok. But if they are taken elsewhere you could simply embed them in your project before deploying to the Go.

fresh wharf Oct 15, 2018, 12:37 PM

#

and that launches fine

sonic lake Oct 15, 2018, 12:37 PM

#

ok

fresh wharf Oct 15, 2018, 12:37 PM

#

i also tried using the video as texture for a globe

#

in an ue4 project

#

and launching that, but would just crash aswell

sonic lake Oct 15, 2018, 12:38 PM

#

I have helped someone else on a similar project and everything worked as expected (projecting on a sphere with inverted normals). Did you look at the log files? What makes it crash?

fresh wharf Oct 15, 2018, 12:39 PM

#

didn't get any log files cause i didnt launch it on the go connected with my pc

#

packaged the project first and then tried it

#

when i launched while connected to my pc it would just work fine

#

i thought that was cause all the rendering was done on my pc

#

which is strong enough to handle it all

sonic lake Oct 15, 2018, 12:40 PM

#

To test on the Go you need to Launch the project on the device

fresh wharf Oct 15, 2018, 12:40 PM

#

yeah it just wouldnt load the picture in

#

the globe would just be black

#

but it worked with reaaaally low res videos

#

so its not that i had it linked falsely or anything

sonic lake Oct 15, 2018, 12:41 PM

#

ok so it was probably a memory issue

fresh wharf Oct 15, 2018, 12:41 PM

#

yeah its a huuuge high res project

sonic lake Oct 15, 2018, 12:41 PM

#

but it is difficult to tell without looking at the log files from the Go

fresh wharf Oct 15, 2018, 12:41 PM

#

like 1 plant alrdy was 700k polygons

#

cause designers made it super good looking

#

i dont have the logs anymore, i'll try setting it up again and passing you the logs after everything is set up

sonic lake Oct 15, 2018, 12:42 PM

#

you can share the error here, you get access to more "brains" able to help you

fresh wharf Oct 15, 2018, 12:43 PM

#

where would i find the logs?

#

cause last time i didnt see it spit out a log file

sonic lake Oct 15, 2018, 12:48 PM

#

#

you have to retrieve if from the device

well, you have controllers in your hands - while swinging them you can't do anything else

#

with legs swinging you get to run'n'gun

#

but

#

if it doesn't help with motion sickness it's no use

tired tree Oct 15, 2018, 2:56 PM

#

"run" sitting in place

sonic lake Oct 15, 2018, 2:57 PM

Cyber-sickness is mostly due to oculo-vestibular mismatch. I don't see how that device could solve it per se.

tired tree Oct 15, 2018, 2:57 PM

#

running in place in roomscale is strictly better when setup correctly

#

they literally could have just done that

sonic lake Oct 15, 2018, 3:08 PM

#

We have experimented quite a bit with the 3D Rudder, which provides a nice way to steer a VR experience with your feet, but doesn't have any particular effect on limiting cyber-sickness.

#

3drudder seems like to good device for mecha sims. I fail to see why would you want to use it for legs-based motion. The whole idea is better immersion. It feels that with player physically moving legs immersion is deeper than with anything else.

#

I fail to see why would anyone want to not be able to physically relate to what's happening in VR.. That's the whole idea of VR - to be in another world, physically

fresh wharf Oct 16, 2018, 7:36 AM

yeah i found it, just wondering what mipmap's do

jaunty shell Oct 16, 2018, 7:37 AM

#

In computer graphics, mipmaps (also MIP maps) or pyramids are pre-calculated, optimized sequences of images, each of which is a progressively lower resolution representation of the same image. The height and width of each image, or level, in the mipmap is a power of two smaller than the previous level.

might be something related to go then

fresh wharf Oct 16, 2018, 8:02 AM

its like it refreshes every frame

and makes it white or black for a milisecond

#

and then switches back to the sprite

sonic lake Oct 16, 2018, 8:06 AM

#

there is something wrong, it should not flicker

even if it may appear low res, flickering is something else

hmm so it isn't a scale issue

fresh wharf Oct 16, 2018, 8:18 AM

#

i feel like the go cant really handle the super high res refresh rate

#

i think i might have to make it so that ue4 plays the video straight from the gallery

but im not sure if that is even possible

jaunty shell Oct 16, 2018, 8:24 AM

I've played 4k videos and up on the first gen GearVR

else it really looks like there's no depth in the scene

sonic lake Oct 16, 2018, 9:32 AM

#

or need to use photoshop and split it into two distinct images

jaunty shell Oct 16, 2018, 9:32 AM

#

yeah

#

that said

#

wouldnt this kind of image import as a Texture2D ?

#

thus not be considered as a cubemap

#

ah you need the nvidia texture tool plugin for photoshop

#

https://docs.unrealengine.com/en-US/Engine/Content/Types/Textures/Cubemaps/CubemapTools

sonic lake Oct 16, 2018, 9:42 AM

#

yes, I also believe they need to be converted to cubemaps

https://docs.unrealengine.com/portals/0/images/Engine/Content/Types/Textures/Cubemaps/CreatingCubemaps/Cubemap_NegativeZ_Vis.png

#

that kind of stuff is a result of non equirectangular stuff also

sonic lake Oct 16, 2018, 9:43 AM

#

plugin from NVidia is pretty old

#

2012

jaunty shell Oct 16, 2018, 9:43 AM

yeah :/

#

the whole section is from unreal 4.9 on thewiki

#

only content that worked perfectly with my material setup were from https://hdrihaven.com/

#

I have no clue how they setup their cubemaps though

#

also seeing how that website got more and more success

#

its awesome to see that you can almost pay a man a whole monthly salary with patreon

#

now the top is distorted Thonk

#

now it duplicated on the x axis

#

im genuinely confused

sonic lake Oct 16, 2018, 9:55 AM

#

@jaunty shell Found a more recent plugin from Intel: http://gametechdev.github.io/Intel-Texture-Works-Plugin/

#

I am getting a DDS uses an unsupported format when importing to UE4 😦

#

@jaunty shell Any hint from the format of your HDR images?

fresh wharf Oct 16, 2018, 10:02 AM

#

@sonic lake it the material looks fine in the material editor, but when i add it to the sun, it looks like it uses the mesh 2 times, 1 for top half and flips and uses it for the bottom half aswell

sonic lake Oct 16, 2018, 10:03 AM

#

And you are using the same texture I shared above?

fresh wharf Oct 16, 2018, 10:03 AM

#

yup

#

using the same blueprint you showed aswell

sonic lake Oct 16, 2018, 10:04 AM

#

Did you change any parameter in TexCoord?

#

I am going to post the blueprint on PasteBin wait

fresh wharf Oct 16, 2018, 10:06 AM

it shows the proper textur in the small preview left top of the screen

And uncheck 2 sided in the material, you don't need it

fresh wharf Oct 16, 2018, 10:19 AM

#

thanks for all the help finally got it properly in my editor

#

gonna check now if the quality is better on my go

sonic lake Oct 16, 2018, 10:28 AM

#

what was the issue then?

fresh wharf Oct 16, 2018, 10:29 AM

#

when i used your sphere it suddenly worked

#

you sphere doesnt appear when i launch through go though blobsad

#

when i launch with a motionControllerPawn inside your sphere with my material on it, it just shows all black with the two hands from the motionControllerPawn

sonic lake Oct 16, 2018, 10:31 AM

#

i am trying as well wait

#

it's compiling the shaders for Android, it is going to take a while...

fresh wharf Oct 16, 2018, 10:52 AM

#

Take your time

fresh wharf Oct 16, 2018, 11:13 AM

#

@sonic lake fixed it by adding a skylight. but the lines around objects are still not sharp, it looks like they've all been cut by zigzag scissors

sonic lake Oct 16, 2018, 11:53 AM

#

what you see is aliasing

fresh wharf Oct 16, 2018, 12:01 PM

#

so i should disable aliasing or alia more?

sonic lake Oct 16, 2018, 12:10 PM

#

if you disable anti-aliasing it will become even more aliased (aka jittery). you should increase anti-aliasing.

#

My whole system crashed for some reasons, so I am rebuilding it

fresh wharf Oct 16, 2018, 12:23 PM

#

oof goodluck

sonic lake Oct 16, 2018, 12:41 PM

#

ok I am back

#

I see the aliasing as well, but take into account this is a bitmap that you are seeing so the antialiasing the engine uses for 3D rendering doesn't apply

fresh wharf Oct 16, 2018, 12:42 PM

#

so that means that i cant improve the anti-aliasing anymore?

sonic lake Oct 16, 2018, 12:44 PM

#

the aliasing is in the bitmap itself

#

now that you have it working, try with your images

#

that test image is pretty harsh on aliasing

#

there could also be some texture compression still going on into UE4, which causes the aliasing artifacts

fresh wharf Oct 16, 2018, 12:52 PM

#

with my own image and forward rendering and max aasing enabled it still looks like the pitcure is moving along the edges

jaunty shell Oct 16, 2018, 12:56 PM

#

@fresh wharf have you tried with a higher mesh density sphere ?

#

the one I have has 3968 tris

fresh wharf Oct 16, 2018, 12:57 PM

#

nope i haven't

#

didnt know you could do that

#

it was a custom sphere from marco

sonic lake Oct 16, 2018, 12:58 PM

#

mine has 960 tris

#

but how is the density of the mesh going to affect how the texture is mapped onto the UV map?

#

the resolution of the UV map may play a role

fresh wharf Oct 16, 2018, 1:05 PM

#

so that you have a smoother sphere to map your uv over?

jaunty shell Oct 16, 2018, 1:06 PM

#

yeah exactly

#

say you map your video to a very low resolution sphere

#

when you look around, you'll see the faces of the sphere

#

and the video/photo will look weird

fresh wharf Oct 16, 2018, 1:06 PM

#

how do i change the tri count of the sphere? cant find a property in the editor

jaunty shell Oct 16, 2018, 1:07 PM

#

you have to do it with a 3d modelling software

fresh wharf Oct 16, 2018, 1:07 PM

#

pepehands i dont have any, time to go find one that does the trick

jaunty shell Oct 16, 2018, 1:07 PM

this is the sphere from the StarterContent Skybox

fresh wharf Oct 16, 2018, 1:08 PM

#

but tbh i dont think it'd make any difference if the aliasing thing happens for EVERY line i have

#

it got doubled again

#

📎 Screenshot_50.png

sonic lake Oct 16, 2018, 1:31 PM

#

I have done few tests with a highres sphere on the rift, both look sharp the same to me

#

But when launched on the Go I still see aliasing no matter what

#

So there is something in the cooking process that seem to compress the texture

#

I don't know what though. I have taken all compression options to max and it still does it.

#

Which is interesting because on paper the Go has a higher resolution than the Rift

fresh wharf Oct 16, 2018, 1:36 PM

#

it's probably just that the go can take a lot less workload than the rift can

#

cause the rift has a pc attached

#

if i launch it on my htc vive

#

it runs perfectly smooth

#

0 weird edges

mighty carbon Oct 16, 2018, 1:37 PM

#

well, if you use Forward Shading and MSAA, you won't get any AA on images

#

only geometric edges get AA'ed

fresh wharf Oct 16, 2018, 1:38 PM

#

i used forward shading

#

set MSAA to max

#

and nothing changed

mighty carbon Oct 16, 2018, 1:38 PM

#

and it won't

#

MSAA doesn't AA images

sonic lake Oct 16, 2018, 1:38 PM

#

@mighty carbon note that this is a texture mapped onto a sphere

mighty carbon Oct 16, 2018, 1:39 PM

#

right and I assume @fresh wharf expects the lines and text on that texture to be AA'ed

sonic lake Oct 16, 2018, 1:39 PM

#

I am not aware of the engine being able to anti-alias textures

mighty carbon Oct 16, 2018, 1:39 PM

#

and that will not happen

sonic lake Oct 16, 2018, 1:40 PM

#

however the exact same image/setup looks very sharp on the Rift and blurry on the Go

#

We are trying to figure out why that happens and how to fix it

fresh wharf Oct 16, 2018, 1:40 PM

#

pepehands

mighty carbon Oct 16, 2018, 1:40 PM

#

lock mip level to the highest one ?

#

that's what I do on my skyboxes - have no mip levels or have it locked to the highest

#

then it appears sharp across the board

sonic lake Oct 16, 2018, 1:42 PM

#

Mipmaps are disabled. Texture compression set to the minimum (at least in my case).

#

We tested a higher res sphere but there is no difference.

fresh wharf Oct 16, 2018, 1:42 PM

#

do you use the go aswell? @mighty carbon

mighty carbon Oct 16, 2018, 1:43 PM

#

yeah

#

I haven't done too much on Go yet

#

but I had blurry skybox issue in my Gear VR project

#

fixed it by setting mip level to the highest

fresh wharf Oct 16, 2018, 1:44 PM

#

you set it to sharpen10?

sonic lake Oct 16, 2018, 1:45 PM

#

@mighty carbon how did you set your mip level?

mighty carbon Oct 16, 2018, 1:46 PM

#

I don't have UE4 with me right now

#

Mip Gen Setting: None or something like that

#

I'd have to open my project and see what I used there

sonic lake Oct 16, 2018, 1:47 PM

#

we also have it to none

fresh wharf Oct 16, 2018, 2:15 PM

#

@mighty carbon could you check your settings w/e you're available?

mighty carbon Oct 16, 2018, 2:16 PM

#

well, that will be 8 hrs from now

if you can ping me at 7 pm CST, I'll be sure to check

fresh wharf Oct 16, 2018, 3:04 PM

#

cool, thanks a bunch!

#

i'll probs be asleep by then, but if you post your settings in here i'll be sure to check it when i waske up

sonic lake Oct 16, 2018, 3:12 PM

#

@fresh wharf I am seeing a weird thing though. Most of the blurriness seems to come from the LEFT eye. The RIGHT eye is much better. I am puzzled.

#

Or I have eye problems.

fresh wharf Oct 16, 2018, 4:02 PM

#

Hmm, i'll go check if its for me like that aswell after dinner

sonic lake Oct 16, 2018, 4:18 PM

#

@fresh wharf @jaunty shell @mighty carbon Mistery solved. Just check Use Full Precision under Mobile in your material and, voilà it is as sharp as a razor.

mighty carbon Oct 16, 2018, 4:21 PM

#

ha

#

I bet I have that checked too in my project

sonic lake Oct 16, 2018, 4:25 PM

#

I kind of read it somewhere but then forgot about it

#

It triggered me the fact that the left eye was ok while the right eye was slightly offset

#

And that it worked perfectly in the Rift but not in the Go (Mobile!)

#

--> Precision issue on mobile

#

Now I am happy. I get crazy when I cannot understand why something doesn't work as expected.

fresh wharf Oct 16, 2018, 4:41 PM

#

I was just like, is this really the best the go can achieve? What kinda horrible meme is this

@alpine ore Does it run Chrome OS?

I don't think it is supported by UE4

@sonic lake Yeap, runs ChromeOS

I am not aware of UE4 being able to build for Chrome OS

alpine ore Oct 16, 2018, 8:53 PM

That's what I suspected :(, looking for a tablet solution for AR development, but not IOS due to Mac overhead requirements

#

@mighty carbon @sonic lake Actually just found this https://www.youtube.com/watch?v=yH_eTAxjq9Q so seems that could possibly build the apk of the ARCore and sideload it on to the device

alpine ore Oct 16, 2018, 9:06 PM

Yeah, see what you mean, probably have to lose out on the debug side of things as Unreal probably wont detect the Chromebook but I could possibly get access to a Samsung S8 to test/debug on.

Reflection captures are extremely aliased. I have a scene with a neon sign so it has a thin geometry with an emissive material and easily gets aliased at low

dramatically improves reflection capture quality for me without the runtime memory bandwidth cost of having higher res captures

but only supersamples up to 2x right now..

@sonic lake got 1 last problem, when i have emissive lighting put on, the edges of my vision "flicker" a little bit, do you have the same on your go?

#

@fresh wharf I think I am using an emissive material but I don't see such flickering

#

do you have any extra lighting added?

#

cause when i only use base color it appears fully black because there is no lighting

#

cause when i only use base color it appears fully black because there is no lighting

sonic lake Oct 17, 2018, 12:29 PM

No, you don't need it. The emissive material provides all the light you need

#

Plug it into Emissive

fresh wharf Oct 17, 2018, 12:30 PM

#

yeah, weird

#

thats why i was wondering, cause i have nothing special ticked on or anything

#

removed all lights in my level

and plugged it into emissive

#

now it flickers a little and causes a headache if you look at it too long

trail grotto Oct 17, 2018, 12:31 PM

#

@sonic lake im using the deferred shader at the moment

sonic lake Oct 17, 2018, 12:32 PM

#

@trail grotto Can you try to switch to the Forward one, which is what you should be using for VR anyway

fresh wharf Oct 17, 2018, 12:43 PM

#

if i divide the emissive by 10, it barely flickers anymore

#

but when i divide it by 5 it flickers a little

sonic lake Oct 17, 2018, 12:45 PM

#

Is this with a texture? You can also tweak the brightness of the texture.

fresh wharf Oct 17, 2018, 12:45 PM

#

a material

sonic lake Oct 17, 2018, 12:45 PM

#

If it is too bright it may flicker yes

fresh wharf Oct 17, 2018, 12:45 PM

#

it would be perfect if i make it emissive but not glowing

#

cause i feel like the clowing effect makes it flicker

sonic lake Oct 17, 2018, 12:47 PM

#

I had cases in which I had to divide the texture output to reduce the emissive brightness, but ideally you should tune your texture for the purpose.

#

Because if you switch material instance to show a different texture it may require a different divider.

#

Well you can add the divider as parameter to the material instance actually.

#

That would work.

fresh wharf Oct 17, 2018, 12:48 PM

#

so i should make the texture less bright?

trail grotto Oct 17, 2018, 12:49 PM

#

@sonic lake unreal restarted [as expected] viewport has "brick texture" frame around it all scene geometry is grey, and the project is compiling 6000 shaders i'll report back when it finishes

sonic lake Oct 17, 2018, 12:49 PM

#

@trail grotto Yes, that is normal when you switch shader

#

@fresh wharf Or use a parametric divider before the Emissive input

sonic lake Oct 17, 2018, 1:53 PM

#

@trail grotto Does it look any different now?

@sonic lake yes

sonic lake Oct 17, 2018, 2:24 PM

#

@trail grotto I would start by deleting some stuff from your level until it looks right. There might be something causing issues, but I have no experience with Unreal Studio so I am not really sure where to look. Thought it was a shader issue, but apparently it is not.

#

@fresh wharf You need to start the Media Player from a blueprint.

#

Otherwise no movie will play.

Yes

You can add the movie to a plain material and output it to a mesh to see if it works so

#

Then you know the movie is working

#

Then the problem is elsewhere

fresh wharf Oct 17, 2018, 2:27 PM

it runs if i just run it in play mode

but when i launch it onto my go it's just a black screen

#

but i can move my hands w/o any lag so it's not like the go cant handle it

sonic lake Oct 17, 2018, 2:28 PM

#

When you pack a UE4 project movies stay in the Movie folder. Not sure what happens for the Go. It should be deployed to the device anyway.

#

Check the log files to make sure it is copied to the SD card.

#

Also check with adb logcat that there are no errors when playing the movie

fresh wharf Oct 17, 2018, 2:35 PM

#

is adb logcat already integrated, or do i have to install it manually?

mighty carbon Oct 17, 2018, 2:55 PM

#

adb comes with Android stuff that youhave to have installed for UE4 to be able to deploy to Android

sonic lake Oct 17, 2018, 2:59 PM

#

@fresh wharf It's indeed part of the SDK. If you look at your log file in UE4 you will see that it is called multiple times for Launching on the Go.

sonic lake Oct 17, 2018, 4:01 PM

#

@fresh wharf BTW, just came to mind, make sure the movie is a format that the Go can decode. Android cannot decode all formats. MP4 works for sure.

@errant lynx that's likely do to collision setup. Visualize your trace so you can understand whats happening

errant lynx Oct 18, 2018, 8:13 AM

#

It appears to go straight trough but no collision settings on the trace nor the actor seemed to fix it.

sonic lake Oct 18, 2018, 11:06 AM

#

@errant lynx an alternative way to check what is going on is to replace the raycast with a long tiny cylinder parented to the VR Camera and protruding along the X axis. If you get collisions with that one, probably your raycast is setup wrongly.

#

why dont they just display the proper link on the official oculus website

mighty carbon Oct 18, 2018, 1:24 PM

#

can't have it handed on a silver platter 😉

sonic lake Oct 18, 2018, 1:24 PM

#

Maybe for the same reason they push updates to everyone without even notifying you...

#

😜

fresh wharf Oct 18, 2018, 1:26 PM

#

@mighty carbon its probably just oculus not even thinking about it

#

I find them slightly biased toward Unity

#

But Home 2.0 is UE4, so...

fresh wharf Oct 18, 2018, 1:27 PM

#

i just hate that they barely have any proper documentation

#

its like, here you have the goggles, goodluck figuring out w/e you wanna do

sonic lake Oct 18, 2018, 1:28 PM

#

Actually they have improved the UE4 documentation quite a bit recently

#

They just forgot to cover audio spatialization on the Go...

fresh wharf Oct 18, 2018, 1:29 PM

#

just casually forget it LUL

mighty carbon Oct 18, 2018, 1:30 PM

#

@sonic lake heavily biased toward Unity

#

especially for Go/Quest

sonic lake Oct 18, 2018, 1:32 PM

#

True, at least when it comes to the documentation and the answers you get on the forums

#

I feel they are under pressure to deliver revenues, hence their selective focus

sturdy coral Oct 18, 2018, 4:17 PM

#

@fresh wharf I think it is because of the unreal engine license

#

people's ue4 branches don't show on their profile I don't think, even if you are logged in and linked to epic

sonic lake Oct 18, 2018, 5:15 PM

#

Actually there was a missing "-" in the URL. But I think you are right, branches forked from someone else's repo don't show among your public repos.

sturdy coral Oct 18, 2018, 5:26 PM

#

yeah and my forks of other projects show, just not for epic forks

#

but you can still get to it by url

Oculus Rift / Oculus Home with UE4

#

some kind of VRAM memory leak

#

it just keeps going and then crashes multiple times a day

#

seems to of started with a very recent Oculus Home update

#

hey error454 😃

#

Trying to get AR camera passthru frames and I'm looking at OnGetCameraImage. For android devices this just returns hard-coded nullptr...

#

The UE4 AR lib fusion ends pretty quickly I guess since I now have to do things 1 way for ARCore and another for ARKit.

@limber rose is that in game?

In editor @glossy agate

#

Oh damn that sucks. What version of ue4? 4.19 had that issue for a while for some people

burnt cave Oct 18, 2018, 10:57 PM

#

Every time I hit Play in VR it ads about 100-200mb version is 4.20.3

#

And it's not just my project, others do it as well.

sage gulch Oct 19, 2018, 1:07 AM

#

what's the behavior when it crashes?

#

my system seems to exhibit a accumulation or overrun bug in the driver stack, and the headset will still show a display but it resets every 10-15 seconds, lagging fps

#

but it will usually take a few days to show up and was there in 1.x

#

i'm on an i7 / 1070

#

Has anyone been able to get the windows mixed reality analog sticks to work with 4.21?

ornate raptor Oct 19, 2018, 2:24 AM

#

Yeah. Make sure you enable the WMR plugin. It's disabled by default

#

Still kinda buggy. If you have it and the Oculus plugin enabled simultaneously, Oculus users won't be able to use their thumbsticks.

#

And, with WMR, make sure to clamp your haptic feedback scale to keep it less than 1.0. Otherwise it crashes

burnt cave Oct 19, 2018, 2:46 AM

#

It says out of video memory

wild seal Oct 19, 2018, 3:14 AM

#

@ornate raptor Which input are you using? I can only seem to find the touchpad.

ornate raptor Oct 19, 2018, 3:22 AM

#

It should just be motion controller thumbstick

#

For the touchpad, you use spatial input touchpad, if I remember correctly

#

Oh, yeah. Make sure it's using WMR and not defaulting to SteamVR

#

Open your BaseEngine.ini and search for HMDPluginPriority

#

Make WindowsMixedRealityHMD=30. I'm pretty sure it's set to like 3 or something by default, which makes SteamVR initialize instead

wild seal Oct 19, 2018, 3:44 AM

Can I still get room bounds without steam VR?
