Does anyone of you guys also have issues with this new SteamVR input system? We can't seem to get the trackpad to work anymore..

sturdy coral Dec 12, 2019, 10:22 PM

#

@compact kettle make sure your axis binding name ends in an '_X' or '_Y'

compact kettle Dec 12, 2019, 10:24 PM

#

can you expand on that a bit?

#

So we have our new axis event, let's say "Motion Controller (R) Trackpad X", which we add "Vive (R) Trackpad X" to. That would not work?

#

so it would need to be called "Motion Controller (R) Trackpad_X"?

#

doesn't change anything @sturdy coral :/

sturdy coral Dec 12, 2019, 10:41 PM

#

@compact kettle the axis action that you bind to needs to be named with _X

#

and _Y

#

so like Vive (R) Trackpad X bound to "Move_X" in your input settings (I think it must be the Vive binding, not the generic motion controller one)

https://imgur.com/a/rq8lTj4 i cant for the life of me make this work, i have motioncontroller which is where my mcs are, and a hand mesh under it, i want to attach the handmesh to the motioncontroller with a physicshandle so i pulled handmesh out of the motioncontroller so it doesnt get the location from that anymore (1st picture) i have grabbed the hand mesh on beginplay with my physics handle (2nd picture) and im keeping the physics handle location at my motioncontroller transform (3rd picture) but the hands are stuck on the ground behind me all the time like (4th picture) sorry for the wall of text

Imgur

#

if i just put the handmesh under motioncontroller it tracks fine

sturdy coral Dec 12, 2019, 10:43 PM

#

@compact kettle and I think it must end in _X and not just end in X

@compact kettle for my oculus touch in 4.24 i called my thumbstick axis X "motioncontroller stick left axis X" works fine, not sure about trackpad? though (for oculus)

sturdy coral Dec 12, 2019, 10:46 PM

#

ignore the -1 scale, that was just needed for something else that was flipping by -1 elsewhere

#

I'll test with vive wands in a bit, I haven't tried them since upgrading to 4.24

#

for the vive_controller.json the above generated:


                {
                    "mode": "trackpad",
                    "path": "/user/hand/left/input/trackpad",
                    "inputs":
                    {
                        "position":
                        {
                            "output": "/actions/main/in/MotionControllerMove_X,MotionControllerMove_Y X Y_axis2d"
                        }
                    }
                },```

Hey! Thanks a lot, we tried a bit around ourselves as well, and got at least a hint, but it results in the same as your solution does - The events now actually return values, however they don't seem to be mapped between 0 and 1, but rather arbitrarily between 0-X. And X may be anything from 2 to 60, seems kind of random with a weird pattern behind it

void raptor Dec 12, 2019, 10:55 PM

#

try clamping it maybe

compact kettle Dec 12, 2019, 10:57 PM

#

That doesn't work in that case, as 1 may be anywhere on the trackpad, making the rest unresponsive

void raptor Dec 12, 2019, 10:57 PM

#

hmm

nimble edge Dec 12, 2019, 11:12 PM

#

Are you updating the target location and rotation on the physics handle?

void raptor Dec 12, 2019, 11:18 PM

#

yes on tick

#

but no matter how i move my motioncontrollers, the hands dont move at all, except stay behind me when i walk around

compact kettle Dec 12, 2019, 11:24 PM

#

@sturdy coral got it. Actually was an engine editor bug

sturdy coral Dec 12, 2019, 11:25 PM

#

@compact kettle ah ok, what was the bug?

compact kettle Dec 12, 2019, 11:26 PM

#

In editor it just duplicates what they call an action set, each time you change the input manifest or reload it, which then essentially sends all the events times the amount of action sets it now contains. i.e. they don't flush the action sets upon regeneration

#

better expressed, it's an array onto which they just keep appending the same actionSet over and over again

#

void FSteamVRInputDevice::RegenerateActionManifest()
{
    //Adding this line does the trick
        this->SteamVRInputActionSets.Empty();
    this->GenerateActionManifest(true, false, true, true);
}

#

Thanks again for your help though, with this _X and _Y thing

How do I get the player's VR calibrated height?

@eternal inlet @daring pasture here is the RTIK plugin modified to compile on 4.23.1 and to package properly: https://drive.google.com/open?id=14mqAIi2KPb-AWi6kc8idl5Bs5_JybuFI

Sweet thanks @sonic lake !

languid night Dec 13, 2019, 12:32 AM

Instead of matching my Oculus height, it puts my camera around half of my height

tired tree Dec 13, 2019, 2:54 AM

@languid night set tracking level to floor instead of eye

#

oculus starts at eye level tracking for some reason still

eternal inlet Dec 13, 2019, 5:57 AM

#

@sonic lake oh damn my man! wish i knew how to code cpp too... awsome!

pearl tangle Dec 13, 2019, 7:34 AM

#

managed to get the v12 update on quest. Hand tracking is fairly decent quality. Although feels a bit laggier than leap motion. Still will be quite handy, shame they are working on the Unreal version for a while

cosmic shoal Dec 13, 2019, 8:10 AM

#

The tracking is very good but the blind spot in the middle is annoying and the lag is almost unbearable.

#

Carmack did say "it will get better" but I've heard that before.

@eternal inlet you are welcome. Now it is also on my GitHub: https://github.com/vr-marco/rtik

willow trail Dec 13, 2019, 8:56 AM

#

RuneBerg just posted a sample project for the integrated plugin in 4.24 (which is great because I suck at understanding how the engine sorts it's files in projects), but the teleportation arc now start as soon as there's the smallest amount of force of the trackpad (instead of having to give it some force like before). Do you guys know if this is just the plugin choosing to handle that action differently?

eternal inlet Dec 13, 2019, 9:25 AM

#

@sonic lake specifically for ue4 right? Anyone you can recommend? And how did you get into it?

sonic lake Dec 13, 2019, 10:08 AM

#

@eternal inlet Sorry, I posted it twice but I was getting the wrong link from Udemy. This one: Unreal Engine C++ Developer: Learn C++ and Make Video Games

#

Has very good ratings and starts pretty much from scratch. I have that one, the Multiplayer course from the same author Ben Tristem and the other one by Tom Looman.

#

What do you mean with your last question? Into C++ you mean?

eternal inlet Dec 13, 2019, 10:54 AM

#

@sonic lake thanks i may look at it. Its always a challenge to keep focus on my gameprogression it seems heheh.

#

What i meant, was: how did you start with cpp? Ive tried starting up with it a few times and kept getting stuck, mainly because i didnt have a clear goal of what to use it for, but also because i kept thinking it was much easier for me to do with bp

sonic lake Dec 13, 2019, 11:02 AM

#

If you are a visual person, as the majority of people, BP's are great and work just fine. On the other hand sometimes you need to use C++ for performance reasons or to expose functionalities which are not available through BP's. I have been working with C++ long time before UE4, so I just happen to know it already. I also do most of my stuff with BP's, but have few low level plugins and some support code built with C++. @eternal inlet

#

From a motivational standpoint it is easier to learn if you have a specific project to work on.

eternal inlet Dec 13, 2019, 11:10 AM

#

Sounds like a good idea to do a specific project yes, and maybe learn the syntax and such independentæy of ue4

pallid pewter Dec 13, 2019, 11:10 AM

#

building a game in unreal, and noticed that the height in engine doesnt match the height set upon occulus setup, any idea why this could be

#

nvm, apparently it was because i had the sensors above the monitor ??

sonic lake Dec 13, 2019, 11:23 AM

#

@pallid pewter The only reason you enter a height during the Oculus calibration is because that is the way the system can determine where the floor is. Once the calibration is done, the elevation of the HMD respect to the floor should always be correct, unless the VR Origin is moved specifically.

#

Make sure 1. your system is properly calibrated (e.g. shifting the sensors up and down shifts also the floor level, unless you recalibrate), 2. that you are using floor level as your tracking origin and 3. that you issue a Reset Orientation and Position on begin play

pallid pewter Dec 13, 2019, 12:04 PM

#

encountered another issue, when i use the default teleport feature of the vr template, the player height is changed after the teleport

sonic lake Dec 13, 2019, 12:08 PM

#

@pallid pewter very strange indeed. With the original unmodified template? And a fully calibrated Oculus?

pallid pewter Dec 13, 2019, 12:14 PM

#

just redid the setup and still does it, the only modification i have made was rewriting the hand pickup code so it could pick up individual components (using to pick up a procedural mesh)

sonic lake Dec 13, 2019, 12:43 PM

#

@pallid pewter Can you try with a fresh VR template, with no modifications at all

willow trail Dec 13, 2019, 12:49 PM

#

Added some C++ class to my project, when I try to compile in the editor, it tells me that the global namespace already contains a reference to SteamVREditor. Moved the plugin from engine's folder to game's /plugins folder, but getting the exact same issue; Any idea?

flat shoal Dec 13, 2019, 12:55 PM

#

Great, 4.24 changed how WMR headsets report their positions, it seems... and nobody at Epic has a WMR headset to test that with 😦

woeful sundial Dec 13, 2019, 12:57 PM

#

@spare yew if you mean AR on mobile, there are several options to reduce aliasing, depending whether you find it in the camera footage, UI or renderings.

Editing "+CVars=r.MobileContentScaleFactor" (set it to 2) in the DefaultDeviceProfiles.ini. App will use a higher resolution.
enabling Mobile HDR and set Mobile MSAA
setting a desired camera resolution in the AR config. Can be done at runtime, check "get supported AR video formats" and choose a higher resolution.

tired tree Dec 13, 2019, 1:17 PM

#

@sonic lake I remember looking at that frabrik with limits implementation and not being happy with it a year or so ago, didn't feel like it was worth improving at the time. Don't exactly remember why though.

#

A good medium though would be an initial fabrik run as it unrolls nicely to set points, then layer a second run of something else on top of it to get to the final location. Lots of robot arm users are doing that

#

or of course something purely logical like the Berger paper

#

as it allows for direct fine tuning

sonic lake Dec 13, 2019, 1:22 PM

#

@tired tree in the meantime I have updated it anyway to 4.23.1 and it can package properly as a plugin now. Maybe it is useful to someone else. Indeed the implementation doesn't seem to be very efficient. It works but it has a couple of quirks and the tracking has a bit of lag.

#

I wonder if it is worth spending some time to fix it/modify it.

tired tree Dec 13, 2019, 1:23 PM

#

tracking lag may be down to sample order

#

if I remember correctly the actual limits implementation was really naive and would be prone to singularities

#

although, looking at the source right now, it doesn't look too bad

#

and has agnostic planer constraints, which is really nice

willow trail Dec 13, 2019, 1:45 PM

#

Fully exhausted any meaningful google result on this, if anyone has ever had the issue with global namespace already containg the definition for SteamVREditor (even though I made sure they're not duplicate of the plugin anywhere), hit me up!

@flat shoal What you mean?

#

seem's like Epic's Q&A was asleep for the VR aspects of 4.24..

flat shoal Dec 13, 2019, 1:51 PM

#

they've been asleep since 4.23, at least on the WMR side

they have been rolling WMR into openXR

#

so yeah. for the past two versions not much else has been iterated on

compact kettle Dec 13, 2019, 1:54 PM

#

@flat shoal For WMR they haven't been there in the first place

#

absolute joke how sloppy the WMR implementation is. As if WMR itself isn't a fragile piece of porcelain

flat shoal Dec 13, 2019, 1:56 PM

#

mm... I got a Microsoft developer to submit some Unreal Engine patches... I think that's the only WMR love that Unreal ever gets

compact kettle Dec 13, 2019, 1:57 PM

#

Finally WMR got the ability to change the spectator screen mode.. But ofc I had to fix that *** too, to actually show anything under the "Texture" mode

#

and now we can't get the vive trackpad to work anymore. Fixed some aspect of it yesterday, but this new SteamVR input thing is a hot mess. The one thing that wasn't a problem got a solution

#

which fucked everything up

flat shoal Dec 13, 2019, 1:58 PM

#

if you're serious about VR, you really should be using Unity...

#

that shooter thing that Epic did and sold to Facebook was just that... a sale

#

they didn't care about VR before and haven't cared after, it seems

#

I'm putting together a package now for a bug report of a serious performance regression in 4.24

#

don't know for how long we're staying in 4.22 (4.23 is equally broken)

#

anyway, venting over 😛

tired tree Dec 13, 2019, 2:01 PM

#

i mean...they literally just rebuilt the entire input system to support OpenXR

#

thats pretty much not true

spare yew Dec 13, 2019, 2:13 PM

#

@woeful sundial It's simply the camera passthrough I'm having issues with. "Get supported AR video formats" returns 0 when using ARCore - using an ARCore Session and setting to max resolution doesn't fix it either.

@spare yew I see, i only have ios devices here. Mobile MSAA and MobileContentScaleFactor worked great. If you set the Mobile Content Scale Factor for Android to 0, it would set the app to the native resolution of the device. Worth a try?

hello, i have been usin vrexpansion trying to get a simple vr multiplayer game to work. i have had many issues but the most important one is not being able to differentiate between the server and client in the games( ie. passing values, steam names, etc.). the main thing i want to know is how to get the text above the pawn to show the server and the clint names. the server sees their name and the client's name, but the client only sees text above both pawns.

i am also having trouble with actor replication. i have set all my actors to replicate, however only the server is able to interact(pick them up) with them properly but the client cant

tired tree Dec 13, 2019, 6:54 PM

@real needle sounds like you need to start at step 1 and do some multiplayer basics tutorials and read Exi's networking overview

#

@tired tree is it possible to point us at the right direction and help us out a bit? our project is due within the coming week and we really need to solve these issues in order to finish the project in time, if not then its absolutely fine

#

do we have to design the project differently including the logic in order to allow the players to interact with one another? cause after reading the guide i am starting to think that maybe the issue is that we tried to make the game as a single player game without any of the multiplayer issues

tired tree Dec 13, 2019, 7:33 PM

#

@real needle you have to take multiplayer into consideration from the very start generally

#

luckily for you, regarding the gripping part its not a totally hard conversion with my plugin to change to multiplayer

#

but you'll have to go over your non plugin stuff and make sure they all replicate correctly, like the names and things

#

you can PM me with questions regarding the plugin side of things to move to multiplayer, regarding the general networking you need to familiarize yourself with it in engine in general before anything is going to be of much use

real needle Dec 13, 2019, 7:35 PM

#

i mean the issue is that we have set our objects to replicate and ticked everything yet still there are issues in this regard

#

at times we had an issue where the client sees everything

tired tree Dec 13, 2019, 7:36 PM

#

well yeah, you aren't gripping them in a replicated manner

#

as as far as text goes, text doesn't replicate

#

you have to send what you want it to display

#

things don't just magically work with replication unless specifically designed too, like positions

real needle Dec 13, 2019, 7:49 PM

#

@tired tree so in this case, our cards are easily usable by the server yet the client is not able to see the full card and only a blanked out card and the images themselves are separate. our cards consists of different parts and all of those parts are set to replicate too yet the issue is still there. when you talk about replication is it more than just ticking those boxes in the object setting? is it something we have to implement logic wise? my guess is that all of the issues we are facing boils down to replication and the fact that one player acts as the server and the other as the client. so does that mean that we need to include different logics, one for client and the other for server?

thank you so much for putting the time to help us out

tired tree Dec 13, 2019, 7:50 PM

#

not sure what you mean by cards, but if you are setting something like an image, and doing it live then yes it will not replicate just because the object does

#

and yes, it is much more than ticking boxes, you have to set vars to replicate, they don't by default, and handle replicated events

#

i'll start a PM though, this isn't VR related

lean basalt Dec 13, 2019, 9:11 PM

weak harbor Dec 14, 2019, 10:02 AM

@split steeple Good morning! We are having tons of problems upgrading from 4.23 to 4.24, most likely due to SteamVR Input. I have moved all content from the plugin to the project, so that we don't get broken references. When I turn off the plugin in 4.23 the editor starts up but give me some errors (as expected) due to the missing plugin.
But when I switch to 4.24 the editor crashes at launch and gives me this error:

Hi @weak harbor the keys have been renamed to Harmonise them with new engine specs. Normally they should be fine unless you do a VR preview/run.

Issues could also arise if you are using key events and not actions exclusively.

Try (backing up) and removing your defaultinput.Ini . You will need to reassign new keys and actions though.

just fyi, if someone intends to use the spectator screen with WMR, and use the "Texture" mode, you'll have to replace

void FWindowsMixedRealityHMD::OnBeginRendering_GameThread()
{
#if WITH_WINDOWS_MIXED_REALITY
#endif
 }

with

void FWindowsMixedRealityHMD::OnBeginRendering_GameThread()
{
#if WITH_WINDOWS_MIXED_REALITY
        if (SpectatorScreenController)
        {
            SpectatorScreenController->BeginRenderViewFamily();
        }
#endif
 }

in WindowsMixedRealityHMD.cpp

@queen schooner the template works fine in 4.23.1

#

I don't know what would be wrong for 4.24. Probably due to some changes.

queen schooner Dec 15, 2019, 3:44 PM

#

Do I need to downgrade my ue?

sonic lake Dec 15, 2019, 3:44 PM

#

You can install multiple versions in parallel

#

So if you want to play with it, get 4.23.1

queen schooner Dec 15, 2019, 3:46 PM

#

Should I just learn steamvr or check oculus sdk too?

#

if its still worth time

sonic lake Dec 15, 2019, 3:48 PM

#

@queen schooner UE4 uses an abstraction layer on top of both, so you don't really need to learn them

#

There are also specific functions if you need a bit more low level, but very likely you don't need to deal with the respective SDK's

queen schooner Dec 15, 2019, 3:50 PM

so eu will provide me with functions responsible for giving accelerometer value, position of sensor etc?

anyone here had experience with locomotion controls in VR? I have a strange issue when I have something grabbed if it touches the player it effects the control. while moving with the thumbstick the pawn gets pushed in a different direction. I am holding a gun, if I hold a box, and place it near left shoulder samething happens. Very odd!

#

controls work fine, guns work fine, until the player puts them close to body on left and gets pushed in a different direction

sonic lake Dec 15, 2019, 4:32 PM

#

@night linden sounds like you have some collisions going on.

night linden Dec 15, 2019, 4:37 PM

#

@sonic lake Yes I was looking at that, and made me try something. I just been trying, and it looks like when the hand is in the first position, moving that to the player pawn is causing it

#

thanks

#

first = fist

#

anyone seen this before?

sonic lake Dec 15, 2019, 4:44 PM

#

@night linden you are very likely using the standard VR template. When the hand is in fist position, its collisions / physics are active. That's why you get an interaction which you don't get when the hand is open.

night linden Dec 15, 2019, 4:46 PM

tired tree Dec 15, 2019, 5:27 PM

#

@sonic lake might be worth working with that and Parger in combination

sonic lake Dec 15, 2019, 5:44 PM

#

@tired tree Read the paper this morning. Parger is a direct implementation, no solver. I was looking at the Unity code in GitHub but it is a bit convoluted. We may be better off implementing it straight from the paper.

tired tree Dec 15, 2019, 5:44 PM

#

the unity code actually has some errors in it as well

#

I had to fix some of it

#

but its fairly straight forward

#

it offers far better shoulder facing baseline

#

and you can run ik off of it then to meet the defined elbow / wrist locations

#

i have it half implemented sitting around somewhere...

sonic lake Dec 15, 2019, 5:45 PM

#

ok so you are already ahead with that

tired tree Dec 15, 2019, 5:46 PM

#

yeah was playing with the leaning accuracy

#

it needs full quaternion conversion though

#

haven't had the time to get back to it, was thinking about during these two weeks off I have coming up

sonic lake Dec 15, 2019, 5:46 PM

#

XMas IK

#

👍

#

Leaning is pretty good in rtik, that part I like. Elbow becomes imprecise in some situations.

tired tree Dec 15, 2019, 5:50 PM

#

yeah i was fixing tha tspecifically with parger

#

and some singularity issues with turning around while bent with arms behind the back

#

rtik is naive unrolling for things

#

parger as a baseline to get more logical joint poses then the limited ik should be great

sonic lake Dec 15, 2019, 5:53 PM

#

I will keep looking into rtik over XMas

#

Maybe there is the way to solve some of the singularities

#

But I don't have a lot of time for it

sturdy coral Dec 15, 2019, 7:25 PM

I have some of the paper implemented, but it was unclear on a lot of stuff

#

I never got the wrist constraints done

placid spear Dec 15, 2019, 10:25 PM

#

@eternal inlet I own both options 1 and 2 that you listed. Option 1 has the benefits of several features implemented out of the box on the demo map, such as player set up, calibration logic including option to save that calibration data, and object grabbing. The drawback is that the elbows sometimes suddenly pop or snap straight just before you have fully extended your arm. Sometimes, the popping happens when you’re viewing the palms of your hands while your elbows are tucked in to your sides and one of the hands will do a very very small jump. The author included an elbow smoothing algorithm to allow for adjustments, so perhaps this could be worked out. Option 2 offers movement as smooth as Ikinema in my humble opinion, but it was a little harder to make sense of how things were set up. The demos for both don’t make them look promising, but they get better after making many adjustments. Hope this helps 😉

Hi, With Oculus and handling the Input Focus Handling ( https://developer.oculus.com/documentation/unreal/latest/concepts/unreal-dash/ ) - how have people implemented this ? I have tried using the Get VR Focus state on event tick within the level blueprint. If "has focus" True Set Game unpaused, if False set game paused, and then hide the controllers, but even if I am wearing the headset it still being paused. Allow tick before being play I have ticked, but still the same. Any suggestions on where to look? Thanks

i have this VR pawn that can possess other vr pawns, but a problem i have sometimes is that when possessing the other pawn, the camera (your head) will often times be a bit offset on the z axis, and then unpossessing, repossing the other pawn sometimes fixes that (or multiple times doing it eventually you get it centered)

#

is there some command i can call to bind the hmd z axis to the newly possessed actors z axis?

#

tried using reset orientation and position, but it doesnt seem to "obey" the actors z axis

hallow knoll Dec 17, 2019, 4:16 PM

#

@ember forum That sounds like a bug, can you repro in a fresh project?

ember forum Dec 17, 2019, 4:17 PM

#

ill give it a shot Victor

tired tree Dec 17, 2019, 4:45 PM

#

@ember forum talking about orientation off, or positionally off

#

orientation would be expected

ember forum Dec 17, 2019, 4:46 PM

#

i seem to have fixed it temporarily, if i set both the pawn to be possessed, and the one doing the possesssing (that sounds confusing) to 0 world z rotation (at spawn) it possessess perfectly (also had to get pose-device rotation z, and apply that as the possessed actor's rotation)

#

the problem was having both pawns at different rotations at spawn (so i just have to find a way to fix that in the world tho, because they obviously cant stay in that rotation forever)

#

@tired tree yeah orientation is wrong, but noticeably only on z axis, how would you account for that?

#

im going to try, getting the hmd rotation before possession, and then sending that to the new pawn, that could be it

tired tree Dec 17, 2019, 5:07 PM

#

@ember forum the orientation is based on the actors rotation and then your roomscale rotation

#

are you trying to do eye level or floor level tracking

ember forum Dec 17, 2019, 5:07 PM

#

floor

#

pc vr, basically a walking pawn, possess a hoverbike pawn..

#

so if i use the old pawn's hmd rotation, and use that to set actor rotation on the new actor, it works, problem is, if im looking sideways before possessing than thats the new rotation of the camera, so when i turn to face forward again it is completely off...

tired tree Dec 17, 2019, 5:12 PM

#

you aren't thinking of it correctly

#

Actor X+ is your roomscale forward direction

#

rotating the actor rotates your roomscale in the virtual world

#

if you want to align your current hmd facing with the actors current forward, you would want to negate the rotation difference and set the actor to that

#

if you intend to preserve roomscale to actor 1:1

ember forum Dec 17, 2019, 5:33 PM

#

so get the delta rotation of the previous hmd rotation and the new actor, and subtract the actor's Z by that to set the new world rotation, that would be what you said right, negating the rotation difference

#

didnt work for me

I would like to dock items on the L and R hips and over L and R shoulders in a way that is visible to players/spectators. Items will also (of course) need to be held in each hand and possibly docked on a rack on the wall.
This will require a lot of setting transforms for each item, for each socket, so that they have nice orientations.
I am thinking of creating a tool for speeding up this process. Does anyone know of tools that already exist that could help or have any other recommendations for doing this?

Hello all, I'm new to AR in unreal and I have some questions that I hope you guys can help me out with. My first question is, is there a way to limit the amount of bp_placeable actor being spawned so that when a user hits a tracked area more than once it only spawns one instance of the bp_placeable? I know the "Collision Handle Override" in Spawn Actor won't let you place another instance on top of it but if someone moves out of that area they will be able to spawn another instance of the same thing so I'm trying to limit the amount to just one instance of bp_placeable being able to spawn. My other question is, is there a way to maybe limit the trackable area where a user can place a bp_placeable actor?

compact kettle Dec 17, 2019, 7:43 PM

#

@cyan kayak Oh nice, thanks. That's a start. Will look into streamlining this into a proper function and share it back if theres interest

#

One thing VR / UE4 desperately needs - more than controller info - is HMD info.

cyan kayak Dec 17, 2019, 7:43 PM

#

Yeah its terrble but its down to steam to add

#

also you can streamline it just by getting any axis

#

you dont have to loop through all actions

compact kettle Dec 17, 2019, 7:44 PM

#

i.e. what Headset is actually being used. Oculus and SteamVR have somewhat working APIs for that, but we had to write our own wrapper around it.. And all WMR headsets always just say "WMR"

#

funny, as some manufacturers want license fee based on how many of our customers are using their hardware, yet there isn't a native way to tell..

#

ah okay

#

will take a peek

#

Currently we have to force the vive wands for SteamVR, but actually on our next patch todo was integrating new controller meshes, so thanks for that

tired tree Dec 17, 2019, 7:55 PM

#

@compact kettle you can directly query the device propeties for manufacturer / hmd information

compact kettle Dec 17, 2019, 8:06 PM

#

how would you do that?

#

I have wrote a wrapper for each VRSystem, called GetProductName, which for Oculus calls ovrp_GetSystemProductName2, and GetFStringTrackedDeviceProperty(VRSystem, vr::k_unTrackedDeviceIndex_Hmd, vr::Prop_ModelNumber_String); for SteamVR

#

however, oculus always returns an error

#

and SteamVR returns "Vive Pro MV" for both the Vive Pro and Vive Pro Eye

#

etc

tired tree Dec 17, 2019, 8:08 PM

#

those are their identifiers for those headsets, you'd have to query feature sets on the vive pro

#

if you are using wmr over steamvr you can drill it down

#

the wmr specific plugin likely doesn't have anything for that currently

compact kettle Dec 17, 2019, 8:11 PM

#

Yeah, we cannot force our customers to use SteamVR though, unfortunately. Really hoped OpenXR would bring an API for that

#

Wonder why this isn't a fundamental feature, or no one is missing it

tired tree Dec 17, 2019, 8:12 PM

#

well they want it headset agnostic, you "shouldn't need to know"

#

but i haven't specifically checked to see if openXR has something for it anyway currently

#

since its wmr and oculus only atm

compact kettle Dec 17, 2019, 8:12 PM

#

for WMR we call HMD->GetDisplayName(), but it most of the time it returns just "WindowsMixedRealityHMD"

#

It's kind of inconsistent, it seems very Beta. Also veries between packaged and editor, it sometimes seems like

#

who's "they"?

#

One manufacturer specificaly plans on charging us based on the amount of customers using their hardware

#

so it kinda is a big deal to know the correct numbers

tired tree Dec 17, 2019, 8:14 PM

#

well even the steamVR name check is differently formatted

#

you will get Vive Controller MV, Vive. Controller MV, Vive Controller . MV., ect

#

no consistancy

#

the origin name should be somewhat constant now at least

compact kettle Dec 17, 2019, 8:15 PM

#

Yeah it's a mess.. Controllers should be even more important, and that really is something everyone should know in their game, if they want to show virtual controllers

#

Wonder what API SteamVR itself uses

#

under Settings -> Video it has a more accurate and consistent name

tired tree Dec 17, 2019, 8:17 PM

#

well there is mesh loading which is intended to auto generate controller models for you

#

but yeah, there are plenty of reasons to want to know an exact model

#

specifically currently there is no offsets that you can apply in steamVR from different controllers, so its useful to know the model to adjust snapped grips

compact kettle Dec 17, 2019, 8:27 PM

#

what's that mesh loading you are talking about? Sorry, but yeah we are currently working on allowing users to select controller overrides to make up for the inability to determine the correct ones by ourselves, so if there's any other way, that'd be sweet

tired tree Dec 17, 2019, 8:32 PM

#

@compact kettle well for one you can manually load the mesh yourself, i have samples for that

#

but for two in engine you can tick a boolean on the motion controller now and it will auto generate the mesh

#

should work on oculus / steam platforms

#

unsure on openXR

#

yeah not implemented on wmr specific plugin or openxr currently, checke

compact kettle Dec 17, 2019, 8:35 PM

#

If you mean just importing custom meshes and offseting them to match the real controllers, with "manually load the mesh yourself", then yeah that's what we are doing already. Issue was just determining which ones it actually were. Will look at this boolean you mentioned

tired tree Dec 17, 2019, 8:35 PM

#

no its an asset manager for the vr systems in engine

#

all of the ones that implement it will auto generate the mesh for you

compact kettle Dec 17, 2019, 8:36 PM

#

with animation?

tired tree Dec 17, 2019, 8:36 PM

#

manual loading was doing it yourself instead, but the automatic one is working since 4.23

compact kettle Dec 17, 2019, 8:36 PM

#

i.e. capacitive touch, thumbstick movement

tired tree Dec 17, 2019, 8:36 PM

#

in the steam one it will load sub components for each part

#

and you can animate those, but no

#

not automatically animated

compact kettle Dec 17, 2019, 8:37 PM

#

I think currently we only use static meshes anyway, but we do the touch-coloring. Interesting though.

@hallow knoll definitely not a ue4 bug, just something i have wrong with my vehicle pawn setup (i just tried possessing the same walking pawn and the camera is fine)

ember forum Dec 18, 2019, 1:28 AM

#

@tired tree okay, now i really fixed it

#

the whole issue was having the center of the vr root

#

offset

#

on the x axis, it was offset like 20 units

#

so i could be closer to the handle bars

#

of the bike

#

even having 1 unit

#

off

#

results in the z rotation producing weird results... so.. yeah just had to work around that by bring the mesh back instead of the vr root forward

tired tree Dec 18, 2019, 1:29 AM

#

you can rotate around the offset as a pivot too

ember forum Dec 18, 2019, 1:30 AM

#

i dare not touch it anymore lmao, but how so(just out of curiosity) is there a calibration node for that or something?

tired tree Dec 18, 2019, 1:33 AM

no, just rotating around a pivot in local space

actually think there is a somewhat helper node for BP, forget its name though

Is anyone else running into problems with SteamVR 1.9.13 causing a crash due to initialization being run twice at different phases of editor startup?

honest imp Dec 18, 2019, 2:40 AM

#

...Root cause seems to be that if your motion controllers are off, every tick the engine tries to reinitialize them before polling them for positional input, which causes a crash due to the system already having been initialized.

@pastel fern I think 4.24.1 may fix the log spam issue and it wasn't just a verbosity setting

#

haven't finished compiling yet to see

#

but it turns off some developer mode initialization stuff or something

mighty carbon Dec 18, 2019, 5:32 PM

@rich canopy I think they are just shorthanded when it comes to UE4.. In fact, Unity is treated as first class citizen at Oculus.

tired tree Dec 18, 2019, 5:37 PM

#

@mighty carbon ....yet oculus uses UE4 internally

#

think you are reading more into it

it takes a lot more effort to port to new ue4 versions than unity ones

sturdy coral Dec 18, 2019, 5:38 PM

#

ah nope finished compiling, it still happens

I'm not sure what that developer mode and debug input stuff that was removed was doing

mighty carbon Dec 18, 2019, 5:48 PM

@tired tree indeed, but that's what I gather from "inside informers", so to speak

but yeah, I'd imagine with renderer constantly evolving it's not a simple upgrade from release to release

@honest imp - 4.24.1 out now should resolve your assert issues, but let me know if you're still seeing it after the upgrade.
@sturdy coral - the settings being turned on in the Input module that was moved to module startup in 4.24.1 enables the debugging options in the input binding interface.

sturdy coral Dec 18, 2019, 7:10 PM

#

ah ok that makes sense

#

@split steeple what's the difference between debugInput and debugInputBinding?

honest imp Dec 18, 2019, 7:19 PM

#

@split steeple I updated to 4.21 and it seems to be okay. Haven't integrated my engine changes into it yet but none of them should affect vr device stuff. Thanks.

#

@split steeple Er, 4.24.1 rather

split steeple Dec 18, 2019, 7:59 PM

@sturdy coral k_pch_SteamVR_DebugInput will show full controller input, this should only be in Editor mode

sturdy coral Dec 18, 2019, 7:59 PM

ah, show where?

split steeple Dec 18, 2019, 7:59 PM

#

but Im getting, this maybe less useful for gamedevs in general and at this iteration of the input system?

honest imp Dec 18, 2019, 7:59 PM

#

@split steeple Unrelated to VR, but it seems that the datamith stuff that relies on APIs that aren't distributed with the engine code is still in there in 4.24.1, though.

sturdy coral Dec 18, 2019, 8:00 PM

#

within the debugger?

split steeple Dec 18, 2019, 8:00 PM

#

console.. so in UE, should be in VS

#

similar to loglevel 3

sturdy coral Dec 18, 2019, 8:00 PM

#

ah hmm yeah maybe that is it

split steeple Dec 18, 2019, 8:00 PM

#

you can set it to false if you dont need it even in editor mode

#

it can be helpful when troubleshooting input issues, but yeah we can remove that one if devs feel its too much.

#

@honest imp - not too sure about that, I think thats more an Epic question, but if you are getting Datasmith errors, I find adding Enterprise: "false" in the uproject helps sometimes.
I havent seen that issue for a while though, so could just be your build?

sturdy coral Dec 18, 2019, 8:07 PM

#

yeah it is a bit much when debugging other stuff. I didn't realize it was editor only but even there something every tick like that would normally go behind VeryVerbose and be turned off by default if it was in the normal log system

#

may be able to look at verbosity of the other stuff and turn it off unless that is set to veryverbose, or since it isn't really part of the normal logging system wrap it in a cvar or remove

split steeple Dec 18, 2019, 8:13 PM

#

yeah, maybe we'll just comment it out. possibly not too useful for majority of devs.

tired tree Dec 18, 2019, 8:13 PM

split steeple Dec 18, 2019, 8:14 PM

#

hmm.. thats odd

honest imp Dec 18, 2019, 8:15 PM

#

@split steeple Issue was new in 4.24 when they added the Datasmith stuff to the core engine. There are some missing header files which will prevent you form compiling the engine that you can only get from Autodesk, and you can only get it from Autodesk if you're subscribing to 3DSMax to the tune of $400/month or whatever it is. If you strip Datasmith out of your solution it's okay. Just seems like if they're going to have some stuff in there that will prevent the engine from compiling unless you pay a lot for outside software they really ought to wrap it in some IFDEF by default or something to not be a nasty surprise for people just getting into the engine.

split steeple Dec 18, 2019, 8:15 PM

#

this is only in 4.24 btw, it wasnt activated in the Marketplace version

sturdy coral Dec 18, 2019, 8:17 PM

#

hmm yeah I tried commenting it out and it is still hitting the stderr or out

#

maybe with less stuff but still every tick or so

split steeple Dec 18, 2019, 8:17 PM

#

ah ok, then yeah, your steamvr runtime loglevel may be set to 3, try setting it to 2 or 1

#

@honest imp - yeah, not really too sure about that... havent used Datasmith personally, and not gotten any build issues so far either.
@hallow knoll might know better, but I guess this is outside #virtual-reality

hallow knoll Dec 18, 2019, 9:00 PM

I submitted my game to steam and their review came back saying it worked fine on index/vive but crashed for them on opening with Oculus

#

in my engine config, I have it set to prioritize opening with Oculus when possible

#

[HMDPluginPriority]
; Since SteamVR also works with the Oculus Rift, give priority to the native Oculus plugin before trying SteamVR
; Since OSVR also works with either Oculus Rift or SteamVR, give priority to either before OSVR
OculusHMD=20
SteamVR=15
OSVR=5

#

when I test at home and launch my game through steam, it opens and runs just fine, so I am not sure how to reproduce what they are finding with steam submissions

#

anyone ever run into an issue like this?

#

Failure:
Your build has failed our review because the store page lists support for VR Headsets but this feature does not appear to currently be supported.

Headset Support is selected for:

Oculus Rift

After launching on the Oculus Rift the game shuts down after a few seconds. No error messages or crash dumps could be found.

Hi, I have a question. I'm currently working with the vive on a VR project. I'm trying to play the game to test it out, but when I hit the play button, nothing shows up on my headset. The VR preview mode isn't exactly what I want to do either because I don't want to be modifying the level when I'm just trying to test it out. I feel like I'm missing something here - does anyone know what I should be trying to do instead?

sturdy coral Dec 19, 2019, 10:55 PM

#

@dusky elm the vr preview in the play dropdown is what you want, it is for playing in VR and not modifying things; the 'VR Mode' button elsewhere is where you go if you want to edit in VR or simulate in VR without playing

#

there is a bStartInVR setting inside project settings if you want your game to launch in VR when playing packaged builds and editor builds outside the editor (with -game)

dusky elm Dec 19, 2019, 10:58 PM

#

Is there a reason the controllers aren't showing up when I try to do the vr preview?

sturdy coral Dec 20, 2019, 12:15 AM

#

@dusky elm which version? some stuff with 4.24 can end up causing that

#

you may need to clean out your steamvr config folders in case they have an old app association for the engine or something like that, can't remember the exact details but controllers weren't showing up for me either a while back

@mighty carbon looks like it is trying to link in the lib file. Where is it located?

Apparently it is in a separated plugin. Is this the one you are trying to build? https://developer.oculus.com/downloads/package/oculus-lipsync-unreal/

I don't build LipSync and Avatars.. yet. So the build process went well without them. I was just wondering about these warnings and how to resolve them, since I've never seen those in the past.

I don't think that's what I'm seeing. I'm using SteamVR, and this isn't related to reprojection, it's just the z-buffer for one eye being blank. (Or at least inaccessible.)

honest imp Dec 20, 2019, 8:27 PM

Yep, that's it. Apparently having any post process just makes UE4 not render to the left eye

Hell-o all. I am looking for some advice/direction for multiplayer VR motion controllers (Blue Print / UE4 4.23). So far from what I have googled and read up on, the motion controller components do not work properly in VR multiplayer. Also, all examples about how to get around this seem to use GetHandPositionAndOrientation, which appears to be depreciated as of ~4.18.
My question is, what would be the proper way currently in UE4 to tackle motion controllers in multiplayer VR? Are the motion controller components working properly now, or is there a new work-around? I am not looking for a tutorial here, just for someone with more experience to kindly point me in the right direction. Thank you.

pearl tangle Dec 21, 2019, 7:51 AM

#

@nova thorn what do you mean by multiplayer? In a multiplayer setup everything should work as normal, it entirely depends on how you have setup networking. Are you talking about trying to do on the same machine or something?

tired tree Dec 21, 2019, 1:18 PM

#

@nova thorn they fixed the ownership issue that the controllers had originally, you just need to send out the transforms from the owning client and rep them back out from the server. Preferably with some smoothing incorporated. You can directly sample the controllers location and rotation in relative space instead of getting the API values as well.

nova thorn Dec 21, 2019, 4:00 PM

#

@pearl tangle Thank you for your reply. For multiplayer, I am trying to make the game playable for both host/listen and dedicated server. My thought there is that if the netcode can do both that it would be fairly robust and allow more flexibility for the host. Right now I am able to get replication working for only one server type at a time by making blue print tweaks. i.e. when I fix one, something breaks in the other.
For testing I have just one machine though, and I am trying to verify everything I possibly can myself.
@tired tree Thank you. I was pretty sure that my issue was due to a problem with my replication code, but finding out about issues with motion controller components gave me reason to pause. If motion controller components are working now, this helps me to confirm that if the problem is most likely with my code/understanding of networking. I know where to best focus now.

Played Quake2Quest finally. Even after I reduced movement speed significantly, I still got sick after playing through 1 and a half levels in the game (and they added vignette to help with comfort too! ).

For short bursts (sneaking up on something or approaching something with positional precision) linear locomotion is fine though.

Also tried hand tracking.. Felt really raw 😦

I am having an issue with 4.24 where the Index controllers always crash the engine. If steamVR is open and Index controller is switched on, opening UE 4.24.1 will result in direct crash. If I switch on the Index controller after opening Unreal (and steamVR with it), it crashes after the controller switches on. Does anyone have the same issue? Any solution?

Found the issue, SteamVR input plugin was causing issues. Deleted the SteamVRBindings folder and steamvr_ue_editor_app.json from the project config folder and reopened the project. Working fine now.

#

yesterday

#

@sullen vortex ^^

#

since update v12 actually, which I got a few days ago

#

make sure you don't have Quest plugged into PC, otherwise you won't see the hand tracking option

#

and SDK is coming in 2020

#

(no love for UE4 anywhere :/ )

sullen vortex Dec 24, 2019, 4:33 AM

#

So our Unity friends are gonna be getting advantage for the next semester i guess. Still dont understand this kind of things. Why would you publish such an important sdk just for one game engine?

mighty carbon Dec 24, 2019, 4:38 AM

#

well, no, Unity friends already got SDK

#

a lot of emerging tech provide SDKs for Unity and most of them never even bother with UE4.. I don't know why (it can't be purely business decision, cuz adding another decent pool of devs to the project would be a good thing)

#

I've heard that UE4 codes such a spaghetti mess, with a lot of depreciated code still lingering and new code being totally different than previous iteration (and undocumented) that a lot of companies just don't have time/resources to deal with it

#

I am pretty sure UE4 devs here would probably disagree 😉

#

(I don't C++, so I couldn't tell if it's true or not)

sullen vortex Dec 24, 2019, 4:49 AM

Hopefully we can get our hands free asap. Been working on a lot of small projects for training lately and would be sweet getting hand tracking

#

You shouldn't use post process in mobile VR

pearl tangle Dec 26, 2019, 1:45 AM

#

the difference with unity is that the individual developers maintain their plugin themselves, compared with UE4 where the SDK is integrated directly into the engine, so that unfortunately gives some delays so that Epic can also go through the code and make sure it integrates with everything else appropriately

Trying to get a panorama picture into VR, I created a sphere and added image as two-sided material
Then put a pawn at the center

#

Things have been working quite ok so far but now I see the panorama image concave

#

Perhaps I changed some setting but can't find it

#

Any tips?

#

Oh and I'm using HTC Vive

#

Also any ideas overall on how to better use 360 picture? I suppose there's a more convenient way than putting image on sphere

#

And it's creating other problems - like scale, I've tried various sizes from 1 to 50 but VR view is still disproportionate compared to what I see on screen/other 360 image viewers

@broken moat I thought you said it didn’t do it with simulate

and I dont know how to make it stop

All you can really do is search for the place that is doing it, and try seeing if you can add a breakpoint before it happens then step through until it does

@minor hawk 1 has pretty low perf impact

you can also now adjust the bloom kernels in the post process volume and if you set some of them to 0 that will lower the impact (I think some may already get overridden to zeroed out at quality 1 though)

Does anyone know if this still stands for mobile Vulkan https://docs.unrealengine.com/en-US/Engine/Rendering/Materials/CustomizedUVs/index.html ?

Customized UVs

Feature that allows running calculations in the vertex shader to increase performance over running them per-pixel.

#

On mobile, any texture sample that manipulates the texture coordinates in any way takes a slow path. These are called dependent texture fetches. By using the customized UV inputs, you can still implement tiling or world space texture mapping while keeping all the texture fetches independent, which is the fast path.

sturdy coral Dec 30, 2019, 5:27 AM

#

for anyone wondering (told in PM), it is hardware dependent, and some oculus doc says dependent texture fetches aren't a big issue on quest

sturdy coral Dec 30, 2019, 6:14 AM

#

https://developer.oculus.com/documentation/quest/latest/concepts/quest-draw-call-analysis/?locale=en_US
Dependent Vs. Independent Texture Reads
Texture reads are thought to be expensive and should be avoided. However, a dependent texture read on Oculus Quest is only a little more expensive than an independent one. So consider sampling a look-up-table (LUT) instead of more expensive shader operations.
sounds like it may not be an issue there

sturdy coral Dec 30, 2019, 6:25 PM

#

@sweet oracle how much is a little off? You may want to add a delay 0 to make sure camera position ticks after the spawn, I can't remember if that is an issue or not

#

(delay 0 waits until next frame)

sweet oracle Dec 30, 2019, 6:26 PM

#

Let me try that

#

@sturdy coral nope didnt help

#

the issue is the whole rotation is 90 degrees off

sturdy coral Dec 30, 2019, 6:38 PM

#

@@sweet oracle Rotator stuff like that usually isn't good practice because if there is any roll the components can get all mangled, it works for fps because they usually only use pitch and roll and not full compound rotations

#

Better to take forward vector directly and use project against plane node to project it on the floor

#

And as the player looks down lerp to up vector projected on floor plane, as player looks up lerp to down vector projected on floor plane

tired tree Dec 30, 2019, 7:08 PM

@wet igloo
Definately
Most vr games just move the capsule with the head, so you can just use your keyboard to move your capsule component
And you can have your hands stick out infront of your camera so you see what you're holding or interacting with

#

It'll be harder to test and troubleshoot, but it's for sure possible

#

does anybody know how the hands and head from an animBP can be set to late update their positions and rotations? as soon as the frametime goes up the hands start to lag behind the controllers a lot. is it possible in blueprints?

#

we are using the VR expansion plugin

tired tree Jan 4, 2020, 8:57 PM

#

@rigid bear set your skeletal mesh to tick preres the controllers, or change it to tick in during physics or post physics. That sounds like your tick ordering is wrong

#

Also you shouldn't have late updates on

rigid bear Jan 4, 2020, 8:59 PM

#

@tired tree like this?

📎 unknown.png

tired tree Jan 4, 2020, 9:00 PM

#

That should work, setting a tick preres would be better as it keeps the body a tick earlier on the physics thread though.

rigid bear Jan 4, 2020, 9:00 PM

#

so it should be "during physics"?

#

what i am mainly worried about is that the grabsphere looks like its moving a lot faster than the hands as soon as the frametime goes to 8ms... is the grabsphere movement predictive?

#

okay so if the mirror is on(to increase frametime to 8ms) the hand lags behind on every tick group.

#

its fine if the mirror isnt on

tired tree Jan 4, 2020, 9:08 PM

#

Then you have late updates turned on

#

It will always lag behind with late updates on

#

That or you are sampling the position outside of theanim graph

#

Then changing tick order won't matter as you already have stale positions

rigid bear Jan 4, 2020, 9:10 PM

#

the late update is always the most accurate controller location isnt it? i would really like to use that for the hand and head positions

tired tree Jan 4, 2020, 9:11 PM

#

You can't match the body to them

#

Ik won't run during the render thread

#

Also as of 4.23 where they fixed the controller lag on steamvr, the difference isn't too bad anymore.

#

In fact, in 4.24 currently late updates aren't even working on steamvr currently due to a bug. It's hard to notice.

rigid bear Jan 4, 2020, 9:14 PM

#

well we are using 4.24 and as soon as a frame takes longer than 8 milliseconds the lag between hand and controller starts... so late updating is working, right?🤔

tired tree Jan 4, 2020, 9:14 PM

#

Then you are sampling wrong

#

Where do you pull the controller positions from

#

And have you changed any tick ordering from default

rigid bear Jan 4, 2020, 9:15 PM

#

getting the controller transforms inside the animbp event graph on animation update

havent changed any tick ordering besides the try with the body mesh

#

Oh, actually turning on scene catures used to kill late updates

#

Dunno if it still does,but shouldn't cause iklag

rigid bear Jan 4, 2020, 9:20 PM

#

okay so full story: we are using a scene component on the controller components to position the hands correctly.

inside the bp update animation event we are casting to the vivepawn and getting that scene component. then we set a transform to use(in the 2 bone ik) based on the transform of the scene component transform

#

📎 unknown.png

tired tree Jan 4, 2020, 9:23 PM

#

Yeah as long as your skeletal mesh itself is set to a later tick order or prereq tick then it should be functional then.

rigid bear Jan 4, 2020, 9:47 PM

#

okay my best guess is that its the capture component

#

but we really want to do scopes and we need the capture component for that so... is there a workaround?

tired tree Jan 4, 2020, 9:48 PM

#

Well it shouldn't be doing that period

rigid bear Jan 4, 2020, 10:04 PM

#

okay can 100% confirm now that the capture component is at fault

#

tried it with 0.3 vr pixel density, had a frame time of 1-2ms and it lagged behind as soon as i enabled a 2dcapture component

#

so not only did they break the vr performance for the 2dcapturecomponent(unless you use r.SceneRenderTargetResizeMethod 2) it also breaks late updating like you said before

#

im suprised not more people have complained about this yet. it completely breaks VR shooters that use scopes essentially

#

okay ive disabled low latency update on the controllers now. the grab spheres are fine again and dont feel floaty at all. when low latency updates was turned on and a scene capture component 2d was activated it looked like the controller was faster than my actual controller IRL

#

if anybody has an explanation for that enlighten me since i am massively confused about that. i didnt know that low latency updates were using predictions. until then i believe that epic/mordentral found a way to time travel.

@tired tree is there a good explanation somewhere online how the engine handles low latency updates? it looked like it worked fine until the broken capture component was introduced into the mix

tired tree Jan 4, 2020, 10:55 PM

#

It just reprojects the render data on the render thread based on a stored last position of the motion controllers and a new sampled one. And no, they don't describe how it works anywhere, you just have to read the source. It's pretty basic though, just applies that offset to all child primitives.

there are many ways of doing this and it's just general Blueprint programming stuff

the way I'd do it is hide them before teleporting player to the level where controllers should be invisible and have logic for hiding them to be event based (not on tick), in player's BP or in controller's BP (if your controller is a standalone actor and not part of the player's BP)

A custom mirror mode is probably what you want, it is just finding the right uvs to crop it

Then make the mirror span both monitors

Mirror mode means what exactly mirroring my camera view and only showing one eye?

#

So expanding the windowsize ?

#

Too bad it has to be two separated windows :/ because it should be like in unity

sturdy coral Jan 7, 2020, 5:27 PM

#

With a custom mirror mode you can show both eyes, there is already one that does but you will need more control over the crop and spacing

#

If your 3D tv is interlaced you could do it in one window

iron zodiac Jan 7, 2020, 5:28 PM

#

you could render it to a render target (https://docs.unrealengine.com/en-US/Platforms/VR/DevelopVR/VRSpectatorScreen/index.html)
then crop the uv to get each eye

We don't have a 3d monitor only 2 projectors

sturdy coral Jan 7, 2020, 5:28 PM

#

It would still be one window with mirror mode, just spanning two desktops

brisk spade Jan 7, 2020, 5:29 PM

#

One window and overlaying it with two projectors .

#

Sweet spot is to crop the windows correctly

#

Have to dig deeper into cropping and mirroring the view

sturdy coral Jan 7, 2020, 5:37 PM

#

you basically want to calculate the fov you want on the projector, and calculate how to make make the centers of each eye mirror spaced 50mm apart or so so they recede into the screen (you want to choose a spacing on the minimum IPD of someone that will be viewing)

#

your crop will need to be a little off center as a result, but not by much on a projector since 50mm or so is really small compared to overall size

@mild trail I think during cook it may be compressing it for mobile with a different method than desktop

#

or depending on how blurry, the mip streaming heuristic isn't working well and you are blowing all of your memory on quest

The textures works fine if I dont use real world mapping. I just really really want to use real world mapping because it is a huge part of our usual workflow.

#

didn't they have delays for original Pimax and not everyone got their HMD yet?

sturdy coral Jan 8, 2020, 2:53 AM

#

@mighty carbon 8K X mentioned there is the one that has been delayed heavily

#

the others only came after a delay too, same as rift kickstarter

#

the main thing is they seem to be reneging on some of the stretch goals and stuff, like eye tracking

mighty carbon Jan 8, 2020, 3:03 AM

#

I see

This used to work up until recently... anyone know if WMR or perhaps 4.24 changed anything?

#

(It doesn't throw any error, but it no longer properly offsets the teleport location.)

#

Maybe this changed?

Hey,
I have packaged an Oculus Quest app which worked perfectly fine when I packaged it last time before Christmas. Now every time I try to open it the app closes straight to Oculus Home after loading for a second.
I have looked through the logs with Logcat, but there are no traces of an error or anything, except that the entitlement check failed. That error has always been there though, and it worked perfectly fine last time.
Anyone else had this problem?

#

@marsh hull that's happened to me before when there's an error in the game. Do you have a null ptr or something?

marsh hull Jan 8, 2020, 9:49 AM

#

@carmine yoke No, I shouldn't have. It works fine on PCVR btw.

carmine yoke Jan 8, 2020, 9:50 AM

#

When you say pcvr you mean a package or in editor?

marsh hull Jan 8, 2020, 9:50 AM

#

But I'll check through for null ptrs just in case

#

Both as a package and in editor.

carmine yoke Jan 8, 2020, 9:51 AM

#

Hmm

#

Well yeah every time that's happened to me on quest it's been a null ptr, but I've not been checking it on pcvr so I can't confirm that

#

Sorry I can't be more help

marsh hull Jan 8, 2020, 9:52 AM

#

Thanks for the help. I'll write if I find a solution 🙂

#

Hello, has anyone ever tried dev AR on VUZIX or EPSON glasses?

#

Thanks

marsh hull Jan 8, 2020, 11:44 AM

#

@carmine yoke I got my issue fixed by removing maps from packaging and adding them again.

carmine yoke Jan 8, 2020, 11:52 AM

#

Hmm, that's odd, thanks for letting me know though!

brisk spade Jan 8, 2020, 1:44 PM

#

can someone explain me how i can set up a loading level splash screen?

#

the splash screen is called before the level is opened

#

i have no idea what type of texture i have to use

brisk spade Jan 8, 2020, 2:04 PM

#

forgot to use another compression mode

vagrant drift Jan 8, 2020, 2:13 PM

#

For a VR device its best to have a map with a object that renders a widget. You can also have this follow the HMD to keep it visible during its duration no matter where they are looking.

tired tree Jan 8, 2020, 2:14 PM

#

its best to have it as a stereo layer typically

brisk spade Jan 8, 2020, 2:28 PM

#

ah gotch

#

just a widget attached to the viewport

pastel fern Jan 8, 2020, 2:29 PM

#

Are you guys able to work with HapticFeedbackEffect_... assets? The asset editor is empty for me

brisk spade Jan 8, 2020, 3:19 PM

#

@sturdy coral hey i tried to get the stereoscopic thing to work.
SceneCaptureComponent2D is what i have in my Motion Controller pawn that renders to a textureRender2D

the res

#

thats my result

tired tree Jan 8, 2020, 3:22 PM

#

you dont' want to use a scene capture

#

you likely want the double eye texture buffer and split it

#

like the both eyes mirror mode

brisk spade Jan 8, 2020, 3:22 PM

#

double eye texture how to set it up or where can i get it from?

#

can i get it from my hmd?

tired tree Jan 8, 2020, 3:24 PM

#

FDefaultSpectatorScreenController

#

virtual UTexture* GetSpectatorScreenTexture() const override;

#

virtual void RenderSpectatorModeUndistorted(FRHICommandListImmediate& RHICmdList, FTexture2DRHIRef TargetTexture, FTexture2DRHIRef EyeTexture, FTexture2DRHIRef OtherTexture, FVector2D WindowSize);
virtual void RenderSpectatorModeDistorted(FRHICommandListImmediate& RHICmdList, FTexture2DRHIRef TargetTexture, FTexture2DRHIRef EyeTexture, FTexture2DRHIRef OtherTexture, FVector2D WindowSize);

#

undistorted and distorted eye functions both display both eyes

brisk spade Jan 8, 2020, 3:25 PM

#

how ould i do it with blueprint only?

tired tree Jan 8, 2020, 3:25 PM

#

you can't

brisk spade Jan 8, 2020, 3:25 PM
