[granite jacinth]

if they can "upgrade" their phone hardware

then it just means, that they will always get the best of the best every year

think Magic Leap

but 3000 less

(plus phone price I suppose)

but since you'll have dual purpose for phone, maybe not add

[cunning depot]

Isn't the processing power of a phone far worse than that of the minimum requirements for an Oculus Rift or a HTC Vive, meaning the games running are either extremely heavily optimised (along with worse textures) or run like shit?

[granite jacinth]

Have you played on a Go or Quest?

Or Focus

[cunning depot]

Nope but I'm curious to

[wicked oak]

beauty

[granite jacinth]

Hard to explain

But, you're wrong 😃

[cunning depot]

Interesting kk 😛

[granite jacinth]

Or right

Depends on context and expectations

[cunning depot]

Mhm

[granite jacinth]

I'm generally surprised each time I played on my Go/Focus and what I was able to play on the Quest

[wicked oak]

you tried the quest, no?

at Connect

[granite jacinth]

yea

[cunning depot]

I usually treat my PC as my beast, giving it an 8086K and GTX 1080, so I have an assumption the VR experience on a phone is no where near as good

[granite jacinth]

That's why I can say that it's surprising what we devs can do on that hardware

[cunning depot]

But pretty cool 😛

[wicked oak]

Quest superhot is the real deal

its the full size version

finally

hellomonkey on mesh shaders

using textures for the vertex data

[dusky moon]

Is it just me ? every single announcement by HTC vive in the past 2 years after the launch of Vive itself was so underwhelming.
this silly product design (the controllers lmao)

[granite jacinth]

IMHO, there must be a lot of internal issues at HTC

They are spread too thin

Their big mistake was selling off most of their phone div to Google

which ended up costing them a lot of money in the long term for that initial lump sum of $

HTC's VR division is probably undermanned

And receiving a lot less money for R&D

compared to Oculus

Facebook VR w/e it's called now

Facebook Reality Lab

[cunning depot]

I'm sure they, at least now, get a lot less money from customers too because of its ridiculous pricing compared to the Rift

[sturdy canyon]

I like the controllers design. I don't like the headset design

PSVR is still the only one where people can kinda look cool wearing them

[cunning depot]

Though when you're playing in VR, does the headset design even matter? 😂 Other than weight and comfortability

[granite jacinth]

It does to one's mind

[sturdy canyon]

It does a bit

[granite jacinth]

Perception is everything

[cunning depot]

LOoool

[granite jacinth]

Would you buy a cool-looking HMD versus some ugly thing at first glance without knowing the insides?

[cunning depot]

Yeah but that's the point, without knowing the insides 😛 If I did know the insides I'd buy the ugly thing

[granite jacinth]

Your average consumer doesn't know what is inside

[cunning depot]

True fair point, I keep forgetting about the average consumer

[granite jacinth]

They only care what games they will be able to play

[cunning depot]

Mhm

[granite jacinth]

So again, it does have an effect

Whether it's a huge impact or not, it's there

[cunning depot]

Ye

[granite jacinth]

Marketing is everything

[cunning depot]

😭

[granite jacinth]

Quest Launch...

That trailer

You could smell the hype from everyone in that room

[sturdy canyon]

Quest is really fucking good and will have a lot of badass content

Cosmos might be good, but almost certainly won't have the content

And will probably cost way more

[dusky moon]

no but look that design of controllers means they never get big and taken serious! medieval/skyrim aesthetics come on! all the oculus products look just like a serious product that can be mass used... not these silly looks that only satisfies some people's tastes.

[granite jacinth]

Also, another reason they may have went SteamVR is because their terms/agreement with Valve

Not sure how their partnership was for use of the Lighthouses and how much it cost HTC to use them

(if anything)

But, could be a cost-savings thing they went inside-out as well.

Along with the possibility that their terms did not allow for another HMD with SteamVR unless they paid big money. And/or because Valve really is producing their own HMD and they don't want anyone to have LightHouse3.0 tech.

(all pure speculation)

[granite eagle]

Looks like they're going all in on the "eye" marketing

Doesn't give me a lot of confidence unless there's notable improvement to perceivable resolution

[real needle]

Since the Quest is essentially the first VR console, should I be targeting "high end mobile" rendering from the start of my new project? The constraints would be beneficial for desktop performance anyway.

[mighty carbon]

they might update UE4 with mobile Vulkan when Quest is out (or before it's out)

there are still bunch of bugs in ES3.1 for VR in UE4

but sure, why not - the more people use ES3.1 and report bugs to Oculus and Epic, the more chances for it to be fixed and to become first class citizen

[real needle]

Thanks. Reading about Vulkan status now. Maybe i'll just work in the low-medium range PC settings! Moderately stylised anyway so shouldn't be too complex for any option.

[mighty carbon]

Do you have VR hardware ?

(Go in particular, or Gear VR)

if not, you might want to either invest into it (or apply for Oculus Start program) or wait for Quest.

[formal abyss]

Is there any solution to switch your HMD between player controllers when testing VR multiplayer?

[sturdy coral]

@formal abyss if you just want to do it between pawns you could do it with possess, but I can't think of a way to do it with player controllers

yall knew about this ?

[mighty carbon]

Yep

But I didn't see any performance gains in mobile VR

(Maybe because my level is super simple)

[real needle]

@mighty carbon I have a Vive, and likely won't target anything newer or hotter during development (2yr schedule). My main goal is to make something that looks good in first-gen consumer vr and state-of-the-art mobile vr (let's say quest /motion controlled WMR when the time comes), with minimal hassle to port.

[daring mural]

Anyone else here use BIK?

[dusky moon]

Hey guys! I just launched my Patreon for my VR project 'False Mirror' ⚡
check it out here @
https://www.patreon.com/alllesss

[past pier]

Alright im just lost, why do i have 4 touch controllers?

its like its duplicated the player controller?

[sturdy canyon]

Do you have a player in the level and a player spawn point?

I think it defaults to spawning a second player in that case

[past pier]

When i delete the player from the world, it doesnt spawn one, it just goes to the default VR setup

I also have this issue (hang on)

From my understanding, the center of the VR world / the ground, is the center of the world here, but it seems the height it all messed up when playing and im completely confused as to why

[sturdy canyon]

you can easily check if there are two players by scrolling through actors in your level after pushing play

[past pier]

its normal without this setup

[tired tree]

The center of the VR tracking is the center of your capsule

capsules are zero'd at center point

[sturdy canyon]

turn off that capsule's collisions, too

[past pier]

ah there was two

[sturdy canyon]

turn off physics for your player

Well not necessarily

[past pier]

its already off

it was the default player controller

alright, so ive figured out i have two players, and does that mean that the capsule is half way into the ground or something?

[sturdy canyon]

I turn off that capsule. Then player's world location will be the floor center of your VR tracking

the camera will track the head if you click that checkbox, and it will be 1.5m above the player's position

[past pier]

yeah, that makes sense tbf, doubling the half height fixes my issue, so i can walk around and stuff, but its not perfect, thanks for the help guys!

[sturdy canyon]

Oh I guess that capsule is part of the Player Character. It also comes with a movement component

I use the Player Pawn as my base rather than Character and so I don't even have a capsule

[cunning depot]

Just wondering, is this discord able to help people who are completely new to VR development or is it for existing VR developers to discuss 😛

[sturdy canyon]

if you're completely new, your best bet is to start by reading the getting started documentation and testing out an example project

[cunning depot]

Alright ty 😃

[formal abyss]

How are you guys developing VR multiplayer and testing your project? Do you just use 2 HMDs? Or is there another solution?

[sturdy coral]

@formal abyss add a mode in 2d mode that can do some simple emulation of VR, see robo recall for an example of how they did it

then you can test all on one machine

another good tool is make sure everything works with demo recording and demo replays

then you can do stuff and go back and look at it in editor later with the ability to put in breakpoints etc.

the hardest part is completely separate bugs can show up when you are the host controlling a character, when you are a client controlling a character, when you are a client observing another client controlling a character, when you are a client observing the host controlling a character, and when you are the host observing a client controlling a character

[wicked oak]

seems facebook is recruiting vr devs

i got contacted by one of their london office recruiters. Personal message, not a classic mass mail

i managed to get proper multidraw on the mesh shader stuff

now with that, i can render AS MANY MESHES AS I WANT in one single drawcall

of any mesh type i want

tons of meshes in one drawcall

and its unlimited

i can just add as many meshes as i want

"culling"

[mighty carbon]

@wicked oak so, are you quitting PUBG for Facebook VR ?

[wicked oak]

no

perf numbers of mesh shaders, currently super unoptimized

50 million triangles, 2500 drawcalls. GPU 16 miliseconds (60 fps), CPU time too small to measure

[sullen vortex]

guys has anybody used gameworks flex fluids in vr?

[mighty carbon]

@granite jacinth sounds like one of those naysayers

VR lacks content, that's all

Rift is $349 now, VR PC can be built on a budget. There are no AAA games though.

(and really, a lot of PC gamers have VR ready PCs - they just don't care for VR for that simple reason)

[sturdy coral]

wmr is like $200 or less a lot of times

and lots of hardware stuff has come down, ram is still a bit inflated

[sullen vortex]

is any of you using gameworks at all?

[sturdy coral]

gpus have finally come off the crypto boom, we definitely should have been looking at fairly cheap VR-capable laptops by now but aren't quite there yet

@sullen vortex I used VRWorks for a while but they haven't updated it in over a year

probably not going to go back to it

[sullen vortex]

have you checked the nvidia announcement on vr works?

[sturdy coral]

no, I heard some rumblings from ces

have they announced anything UE4 related?

[sullen vortex]

i was asking cause im starting to rough a concept that has fluids and smoke, its for training, and they are a must

its on the nvidia presentation from yesterday

[sturdy coral]

what did it say?

even if they put out a new VRWorks UE4 release now, they've lost my trust that they will keep it up to date, they are behind by 3, almost 4 engine versions on vrworks

[sullen vortex]

looking for it

[sturdy coral]

@sullen vortex have you looked into the vr funhouse example? they have smoke sim on the fire arrows

[sullen vortex]

tried to compile it but threw a ton of errors of missing data

[sturdy coral]

have you tried the version from the stores just to see it?

[sullen vortex]

could succesfully build olento´s branch

yeah, thats a modding tool, cant do so much

here is the announcement, it seems to be related to the new htv vive pro eye and foveated rendering:

"The controllers are nearly identical to the Oculus Rift, but wireless ..." << lol, as if Touch controllers are wired

[formal abyss]

so its like a better google cardboard?

[frigid kite]

In the same way that a smartphone is like a better Nokia 3310, yes

[sonic lake]

@frigid kite 😂😂😂

[balmy surge]

Having an issue at the minute where I need to create a VR game where you can enter a car. The current issue is that the inside of the car is too dark but if i up the brightness the outside looks washed out. any ideas would be really helpful. (also i'm not able to use spotlights)

[frigid kite]

First off, make sure that the actual colors of your car aren't too dark

Next, use exposure instead of more light to change perceived brightness

[balmy surge]

we have an expert that does materials so that's not the issue unfortunately

that makes the outside of the car look really washed out

[frigid kite]

Hmm, maybe play with the skylight intensity to fake GI inside the car?

[balmy surge]

Again it makes env look really washed out :/

[frigid kite]

Can you share some screenshots on how it looks, from inside and outside the car?

[balmy surge]

Sorry man under NDA cheers for help though

[frigid kite]

Hmm yeah I understand, it's hard to get a grasp of the problem otherwise though

[balmy surge]

yeah its a pain in the arse

[frigid kite]

Is it just the shadows of the car itself? How does it look if you turn off shadow casting on the car?

[balmy surge]

same issue there is just not enough light able to get in the car going to have to fake it while trying to make it as realistic as possible 😂

[frigid kite]

If the car is not casting shadows, then all light would be going into the car

[balmy surge]

looks like lego if we do that

[frigid kite]

Yes, just trying to pinpoint the issue

[sonic lake]

Turn off eye adaption / auto exposure for the VR camera

^^^ @balmy surge

[balmy surge]

Cheers man

[abstract panther]

Im trying to make a material switch from a 3D menu, might be on the wrong path here, https://gyazo.com/834fb30bd06541c7b3595d78ba57cad8 - https://gyazo.com/7fc4833bb4c7034d310e972781f853ae is there anything I could do ? Cause when pressing nothing happens

[sonic lake]

@abstract panther use Print String to check your input events are firing properly. If they are, then the issue may be with the code after them, even though it seems correct to me.

If you are using Oculus, be aware that the input events from the controllers are not firing unless you wear the HMD or bypass the proximity sensor from the Debug Tool (or put a finger on it).

[frigid kite]

Also, if you have more than one thing hooked up to the right trigger, make sure that "Consume input" is not enabled for the input events

[hallow knoll]

@abstract panther By default UMG buttons is looking for "Press" AND "Release" pointer events

So on Motioncontroller (R) Trigger Release, add "Release Pointer Key" - Left Mouse Button

[tired tree]

Also might want to check if is hovering over an interactible widget

[hallow knoll]

You can change this to "down" if you don't want to wait for release of the trigger

[granite jacinth]

@hallow knoll Only one Victor allowed here

@wicked oak we got another one

At least your last name doesn't start with a B

[wicked oak]

only one victor can remain

oh it does

[granite jacinth]

His?

[hallow knoll]

Well, hence my aliased last name

[wicked oak]

ah

[granite jacinth]

I know yours

[hallow knoll]

Can't be like you guys

[tired tree]

I prefer yellow Victor

[granite jacinth]

¯_(ツ)_/¯

White Victor the best

[hallow knoll]

🤘

[granite jacinth]

@hallow knoll So, what do you do for Epic?

[hallow knoll]

Community manager

[granite jacinth]

Ah, that's too bad

[hallow knoll]

Too bad? You just wait Mr.Burgos

[granite jacinth]

heheh

[daring pasture]

Does quest have positional tracking for the headset?

[granite jacinth]

yes

You can play just like you would in WMR

Except, no tether

Works pretty well for games that actually support it

A few Quest games I tried out barely had anything for roomscale, and only used thumbstick loco

So...those games were meh

[daring pasture]

How's the hand tracking compared to the wmr?

[granite jacinth]

felt the same or worse sometimes

But, I think I just had a bad unit, cause a lot of folks didn't get the same issues I had

I think that 75%-90% of the Quest launch titles won't fully utilize its potential though

Since they will just be Rift/Go ports mostly

[daring pasture]

When I used the WMR i noticed you pretty much have to be looking at your hands to reach down and grab things. Wasn't sure if the quest was the same way

[granite jacinth]

But you'll get to the play the #1 VR game tetherfree

[mighty carbon]

oohh, Epic's staff in #vr .. That's interesting

[granite jacinth]

https://giphy.com/gifs/51kSPwZ8OKXBK

[daring pasture]

Rather kill zombies tether free 😉

[granite jacinth]

@mighty carbon yeah, and he actually likes VR...so you can spam him all your requests, moans and complaints 😉

@daring pasture My thoughts exactly :0

[mighty carbon]

as if @hallow knoll going to tell us about the status of mobile Vulkan for Go/Quest in UE4 and what mobile VR goodies are coming into UE4 for Quest 😉

[granite jacinth]

He probably would know anything Oculus-related actually

But guess that's all I'll say about that, just in case

[mighty carbon]

hmm... did yellow Victor run away? 😦

[olive zinc]

I am having issues detecting X and Y from the HMD touchpad on the Gear VR

both mouse input and the get oculus touchpad axis doest seem to fire

[mighty carbon]

Gear VR is dead

[olive zinc]

it only detects a press via Oculus touchpad press

I know, but we have a student project with it 🤷

[hallow knoll]

@mighty carbon I'm here!

[mighty carbon]

\o/

@hallow knoll any chance you have some info to share about what I asked earlier ?

[hallow knoll]

In due time I'm sure

Haven't been here long, but I will make sure to share as much as I can

We're all at the mercy of the engine devs 😉

[mighty carbon]

ha, indeed

[abstract panther]

Thanks for the answers @sonic lake and @hallow knoll I been trying both of the answers it, I am using HTC vive, everything is getting triggered, judging by adding print strings, but nothing is happening, I tried adding release pointer key but still nothing happens 😮

Aswell the buttons only get triggered once

[sonic lake]

@abstract panther How do you select which widget button to click?

[abstract panther]

Trigger buttons

Ohj

Or do you mean how I get up the menu ?

[sonic lake]

How did you configure your Widget Interaction component?

Does it have enough interaction distance?

Did you activate the Show Debug flag so you can monitor it?

If your interaction distance is too short it may look like you are hitting a widget when actually you are not.

[abstract panther]

Ah yes, it has 1000

[sonic lake]

@abstract panther So you see the red dot then the ray hits the widget?

[abstract panther]

Yes

It hovers aswell

and when I click on the button the print string gets triggered

[sonic lake]

So the Press Pointer Key gets triggered

How about the widget event (Pressed/Clicked)?

[abstract panther]

Yes it also get triggerd to the print string at the end

[sonic lake]

Ok I don't see where your Print String are placed

[sonic lake]

So, to summarize, the widget Pressed/Clicked gets triggered properly. Then the problem is in the rest of the code apparently.

Next I would check that Get All Actors of Class returns something valid

You can simply disconnect the rest of the code and print the size of the returned array

[abstract panther]

To the for each or to the get all actors ?

[sonic lake]

Out of Get All Actors of Class

[abstract panther]

Ah gonna try it

[sonic lake]

ok

[abstract panther]

like this right ?

[sonic lake]

Yes, but print the size of the array returned by Get All Actors of Class

Use LENGTH

[abstract panther]

might be really wrong but this ?

[sonic lake]

It's correct actually

Now when you click the widget you should get the number of actors of that class

[abstract panther]

Yep

[sonic lake]

Is it > 0?

[abstract panther]

Yes

[sonic lake]

Ok but then the problem is in your Set Material

You can try to use Toggle Visibility in its place

You should be able to hide/show the mesh by clicking on the widget

That confirms that your widget interaction works properly and the problem is actually in setting the material

[abstract panther]

Ahh smart!

Yeah visbility worked

[sonic lake]

Ok, then you know where the problem is

You have to figure out why Set Material doesn't work as it is supposed to

[abstract panther]

Yeah damn, this stuff got confusing hahaha

[sonic lake]

Is that mesh something you have created?

[abstract panther]

Yes

OMG

I found the issue

Im so stupid right now

[sonic lake]

Did you UV unwrap it?

[abstract panther]

Yes, but it seemed like it was the material index

0 is underneath the floor

1 is the top which I can see

[sonic lake]

That explains it

[abstract panther]

hahaha omg

I feel so bad

[sonic lake]

At least you practiced an end-to-end debug workflow 😉

[abstract panther]

Yes! Thank you so much for the help aswell 😄

[sonic lake]

Don't feel bad, I am sure none here can say it never happened to them. as well.. 😉

[abstract panther]

Haha true 😛

[sonic lake]

Good! You are back in business 👍

[abstract panther]

Yes haha I was about to lose my head

[cunning depot]

From the starter pack for VR, what am I able to delete (files-wise) for Oculus Rift-only support

Default stuff

My first VR project and my first real attempt at Unreal Engine 😭 This is not gonna go well for me (though I understand blueprints and C++ code linking, property windows etc.)

[sonic lake]

@cunning depot Why do you want to delete stuff? There isn't much to delete from the standard VR template.

[cunning depot]

The standard maps?

Am I able to delete everything in that folder?

[sonic lake]

Ok, what are you trying to achieve? Well, yes, you can delete all the maps if you intend to create your own level.

And the geometry related to them if you are going to use your own assets.

[cunning depot]

Yeah I'm basically trying to create my own levels for the game I intend on making and I assumed the standard levels/maps they gave were just examples and can be deleted

But ah ok thanks 😃 Yeah I'll be using my own assets and creating my own level

[sonic lake]

I would go on and create the level, then delete the example maps and geometry. In case anything is referenced in your new level, you will get a warning from the engine. Otherwise it is safe to delete them.

[cunning depot]

Awesome ty for the suggestion, can't find any help with VR developing online such as Youtube so this helps

[sonic lake]

Actually there is some useful material on YouTube.

It depends on what you are looking for.

[cunning depot]

[sturdy canyon]

I don't think they ever got good positional tracking, no.

Spent too much on their massive sales team in SF.

[sage gulch]

is WMR controller support native yet?

my friggen Rift died.. UE will draw to the headset but it doesn't seem to track the controllers, even if the button mappings are different...

oh ok.. are those default mappings a joke :p

can it not tell if you are holding the trigger? wtf?

[wide flare]

The new vive has native support for FOVE interesting

[sage gulch]

Steam needs to be directing users that go to their Error 108 troubleshooting page that they might need the WMR driver package

[torpid steeple]

I recently got my hands on a VR thing for the first time. Has anyone ever done a sort of "Transitioning to VR" video for people who aren't new to Unreal? I feel like the intro materials to VR UE4 stuff are geared toward complete newbies.

Sort of hoping to just learn what differences to be aware of, in terms of UI, inputs, etc. If there isn't anything like that, I'll happily watch the Training Livestreams anyway, though.

This is short of dumb how to get these

It's like Knuckles

Even Pomax doing it

Seems to be a trendsetter

[wicked oak]

looks better than knucles

[granite jacinth]

Not sure I like it

[wicked oak]

knucles top face is super small

its cramped af

[granite jacinth]

How many buttons do you see?

5?

Assuming PK= button

Plus grip/trigger

Dunno. Need to feel it

[wicked oak]

nah, i dont think this looks any final

sony has tons of controller patents

of different kinds

even some absolutely wild stuff

[mighty carbon]

as long as they track well, it will be always better than PS Move

[wicked oak]

they have a joystick

already 1000 times better

[mighty carbon]

yeah

[tired tree]

i'll admit, I actually prefer the wands touchpad over most sticks

but the knuckles touchpad is near useless

so guess any joy stick is better than that

[cunning depot]

Hi, does the VR starter pack come with a moveable pawn because I have my Oculus Rift connected along with the sensors and the controllers (on the Oculus app it shows everything's good) but I can only move my head around, the controllers aren't allowing me to move
The level I'm testing is HMDLocomotionMap, which has a HMDLocomotionPawn

[sage gulch]

try the other map

[cunning depot]

I did, both don't work 😦

Only thing controllable is the camera rotation via looking around with the headset

The circle thing that shows where I'm looking works too, though weirdly it collides and knocks over static meshes that I simulated physics with

[sonic lake]

@cunning depot MotionControllerMap

[cunning depot]

Yeah I tried that, no movement still 😦

Really confused cus the documentation site says the inputs are set up with the starter pack

[sonic lake]

You should see the VR hands in that one

[cunning depot]

Let me confirm, brb

No I don't see VR hands o.O

Hm maybe because I connected everything after I loaded up the project, SteamVR might have done something weird let me check

[sonic lake]

You made a new project based on the VR Template?

[cunning depot]

Yes, I selected VR and selected With Starter Content

[sonic lake]

You don’t need steamvr for Oculus

[cunning depot]

Yeah thought so, initially SteamVR kept popping up when I didn't have Oculus connected but now that I do, it doesn't

Alright after restarting UE4 it still doesn't show my hands/movement doesn't work, only looking around with the headset

The controllers are 100% connected as I have tested the Oculus home place

[sonic lake]

It may be a conflict with steamvr

I would uninstall it

[cunning depot]

It could be, feelsbad I play SteamVR games 😭

[sonic lake]

Ah ok

Then disable the steamvr plugin inside ue4

Leave only the Oculus one enabled

[cunning depot]

Ah yes, since the game I want to create only supports Oculus anyway

Let me try that, I'll come back here soon (I don't even know how to do that but I want to learn the UE4 UI etc.)

[sonic lake]

K

Edit —> Plugins

[cunning depot]

Ah yes found it 😛 Restarting UE4

[sonic lake]

👍

[cunning depot]

Unfortunately didn't work 😦

[sonic lake]

Strange

Engine version?

[cunning depot]

4.21.1

[sonic lake]

And you are in the MotionControllerMap?

[cunning depot]

Yep, I've loaded up the motion controller map then I press "Play in VR" or w/e

I'll give some background of what I've done:

• Got rift a week ago
• Installed Oculus program and played a few Oculus store games
• Installed SteamVR and played a few Steam games
• Installed UE4 and created a VR project from template, then hit play in VR

[sonic lake]

Correct

[cunning depot]

Not sure if there's any issues there but it doesn't seem off

[sonic lake]

Are you wearing the HMD when playing in VR

[cunning depot]

No

I'll actually test that, good idea

[sonic lake]

Then your controllers are not activated

[cunning depot]

Omg

I'm so dumb!

I'll test that rn hahaha

[sonic lake]

Or keep a finger on the proximity sensor

[cunning depot]

Still no luck 😦

I must be doing something wrong in UE if the controllers are working fine in the Oculus menu

I find the issue really strange because I can move my head around fine with the HMD but I just can't move the position using controllers/do anything with the controllers

[sonic lake]

Let me think...

[cunning depot]

Thanks for your help so far

[sonic lake]

Did you activate the unknown sources in the Oculus app?

[cunning depot]

Yes, but wait

It just started working (I see my hands etc.) after I deleted the SteamVR stuff from BP_MotionController

Let me check when I create a new project if this behaviour still occurs

[sonic lake]

Usually that is not needed

The template knows which headset it is dealing with

[cunning depot]

Yeah very weird...

[sonic lake]

But it works now, right?

[cunning depot]

Checking rn in my main project, one sec 😛

[sonic lake]

You see your hands and you can teleport, grab the cubes, etc.

[cunning depot]

Yep it works perfectly! What's even more strange is that in my main project I didn't have to disable SteamVR plugin nor delete from BP

I don't know what changed lol but it works, thanks so much 😃

[sonic lake]

You are welcome

[sullen vortex]

has anyone tried the native mixed reality plugin on UE, thinking in giving it a try instead of using LIV but wanted to check if anybody has already used it succesfully

[wide flare]

you need specific hardware for theirs, its doable to create your own mixed reality system though just need to create a render target and get the correct focal length for your camera

[sullen vortex]

My camera fits their spec. Just wanted to know if anyone suceeded using it & review

[wide flare]

do you have the correct capture card?

thats where I was unable to use their setup

[trail shale]

fuck off Steam VR what's your deal, I'm hitting trigger button,

[sullen vortex]

@wide flare there is no need for a capture card:

https://docs.unrealengine.com/en-us/Platforms/MR/MRSupportedVideoDevices

[wide flare]

USB Capture Dongles

unless you are using a webcam yes there very much is

[sullen vortex]

thats for capturing hdmi signals

i have a Logitech C920

i use it currently with LIV

[hybrid plume]

weather is nice tonight

[eternal inlet]

hi guys, any easy way to detect if your player is using normal wands or knuckles (ev3)?

as others has noted before me, the knuckles trackpad is not very usable when moving thumb from side to side, and the logic i use currently, is to read which hmd i have and then map the trackpad-axis values to movement, but since hmd is still vive, but could be knuckles, i need to know if they're connected, and then use the joystick axis values instead

[sturdy coral]

@eternal inlet they recently updated the legacy binds so I can't say for sure, but on the old ones they didn't even expose the joystick

so you couldn't read joystick axis value

(with th eold input api)

[eternal inlet]

Ok thx 👍🏼

[sturdy coral]

you could read it with the new api

[sturdy coral]

@eternal inlet I think they do have it now actually:

legacy_bindings_knuckles.json

            {
               "inputs" : {
                  "click" : {
                     "output" : "/actions/legacy/in/left_axis0_press"
                  },
                  "position" : {
                     "output" : "/actions/legacy/in/left_axis0_value"
                  },
                  "touch" : {
                     "output" : "/actions/legacy/in/left_axis0_touch"
                  }
               },
               "mode" : "joystick",
               "path" : "/user/hand/left/input/thumbstick"
            },

[eternal inlet]

Thats pulled from src 4.21?

[sturdy coral]

no from knuckles driver legacy bindings, looking closer, they don't have it

axis0 is the same as the touchpad

[eternal inlet]

Oh ok

[sturdy coral]

so you can't distinguish the two

but users can pick either one

I wish they would just bind it to the same axis as WMR so you wouldn't need the new input API

[eternal inlet]

What about detecting if user has wand or knuckle?

[sturdy coral]

I'm not sure if you can give your own legacy binding

@eternal inlet there is a tracked device property string that will tell you

[eternal inlet]

Accessible from bp or i need a bit of cpp?

[sturdy coral]

it would need cpp, I think it may be exposed in @tired tree 's BP library though

[eternal inlet]

Yeah i was told he was exposing it, but was just wondering if it was exposed since natively

[sturdy coral]

@eternal inlet I have:

        // Knuckles doesn't seem to indicate the axis is a joystick when rebinding it!  search for whether we are using knuckles:
        vr::TrackedPropertyError Err = vr::ETrackedPropertyError::TrackedProp_UnknownProperty;
        FString const ModelNumber = FSteamVRHMD::GetFStringTrackedDeviceProperty(VRSystem, DeviceIndex, vr::ETrackedDeviceProperty::Prop_ModelNumber_String, &Err);
        ControllerStates[DeviceIndex].bHasAltstick |=
                (Err == vr::ETrackedPropertyError::TrackedProp_Success && ModelNumber.Contains(TEXT("knuckles"), ESearchCase::IgnoreCase));
        // ~~```

I think I had to modify GetFStringTrackedDevicePropert to have STEAMVR_API

to make it work in the controller module

bHasAltstick is also my own thing from adding joystick support to WMR

I also rebound joystick to the wmr joystick axis through modifying legacy bindings for that so won't work in shipping game I don't think

determining whether it is knuckles will work, but you are stuck with touchpad and joystick as the same axis

[granite jacinth]

Hopefully this is all taken care of in 4.22 or with the SteamInoit Plugin

[tired tree]

@sturdy coral @eternal inlet ue4 doesn't use the legacy joystick binding

in 4.21 with the beta input you can do it though without edits

as for the hardware query, no its not exposed normally

[potent gust]

Has anyone got an issue with the oculus go where the controller is not detected after returning to the app from home with the error message APP_CMD_LOST_FOCUS?

[cunning depot]

Any tutorials out there for VR menus? I've seen some 3D widget stuff on the documentation but I learn far more easily and better with examples rather than just knowledge thrown at me + I don't think the 3D widget page includes finger pointing like with Oculus controllers

[hushed epoch]

Hey guys, I am having a major issue in 4.21 following a tutorial video and can't reproduce the intended result

My only thought is that something significant has changed since the tutorial was made, I am working in the latest 4.21 version

https://youtu.be/EKR8ogonD68

I have triple checked every step, and the result is that both hands/arms use the left motion tracker position, instead of left and right respectively

Here is the modified ThirdPerson_AnimBP

Any help would be greatly appreciated!

The Anim Graph in the tutorial seems very odd, as the components are chained

[sturdy coral]

looks normal to me, each thing takes a pose in component space and does a modification

[hushed epoch]

Any idea why both hands would snap to the left motion controller?

[sturdy coral]

did you pass in different transforms

and do fabrik nodes have the right bone chains

[hushed epoch]

Yes It is exactly like the tutorial, I have gone over every step three times and verified everything

He's obviously in a much older version is the only difference I can find

[sturdy coral]

turn off the one they are both set to

and see if it still happens

if they are both on left, disconnect left fabrik node

[hushed epoch]

Good point thanks

Okay, after disconnecting the left hand nodes, the left hand in fact doesn't track, but the right hand stick tracks the Motion Controller L

[tired tree]

@hushed epoch you might want to message @sonic lake personally, it is his tutorial

[hushed epoch]

This is where I get each Motion Controller and set the transform variables

[sturdy coral]

right click the the MC Transform L and MC Transform R pin and you can tell it to watch them

[hushed epoch]

Thanks @tired tree

[sturdy coral]

@hushed epoch make sure you didn't set the Motion Controller R variable to point to Motion Controller L

and make sure you set the hand inside both

[hushed epoch]

Yeah all that appears to be setup correctly

How can I watch that value during runtime? It doesn't update

Sorry, I am used to C++ development, this Blueprint stuff is totally new to me

[sturdy coral]

@hushed epoch at the top you have to tell it which instance to watch

instead of the preview instance

[hushed epoch]

Thanks

Yeah they are exactly the same value (which is obvious)

[sturdy coral]

@hushed epoch now add the watch in the earlier part where you are setting them from the blueprint

and keep working backwards until you find why they don't differ

if you can't find it there, try a simpler setup where you try to make cube actors follow each hand without an anim graph etc. Simpler and simpler cases until you find where you are going wrong

[hushed epoch]

Yeah all the way back to GetWorldTransform (MotionController_R) both right and left read the same values

yeah that's a good idea, reduce the complexity

[sturdy coral]

can you add a watchpoint on the motion controller objects themselves?

make sure they aren't the same object

[hushed epoch]

Yeah, I think that's where the issue is

Thanks for the help @sturdy coral

[sturdy coral]

np

[sonic lake]

@hushed epoch did you find the issue?

@sturdy coral thanks for the help with the troubleshooting. 👍 @hushed epoch I didn't retest the tutorial with 4.21, but I don't see why it shouldn't work also with this version.

[sonic lake]

@hushed epoch at 3:32 in the tutorial, we duplicate the left motion controller component to create the right motion controller component. Then we change the tracked hand to Right for la latter, so it tracks the right hand instead of the left one. This looks slightly different in 4.21, but it is the exact same principle. Each MC component has to be told which physical controller it is tracking, whether the Left one or the Right one. You may have overlooked this step, so both MC components track the same physical controller, the Left one in this case.

[hushed epoch]

@sonic lake that was it, thank you very much!

I'll have to figure out how to make an IK chain now so the torso neck and head use the head tracking to prevent the camera clipping through, but this is a great start

[sonic lake]

@hushed epoch 👍

[hushed epoch]

Love your tutorials btw, they've been completely invaluable for someone new to blueprints coming from pure C++

[sonic lake]

The other option to avoid clipping is to have a separate mesh for the head and set it to Owner no see.

Thanks! I am happy to give back to the community. 😊

[hushed epoch]

Yeah, I may hide the head as well, but in the long run the player has so much freedom of movement that I think there needs to be a considerable amount work in this area for a full body VR character rig

[sonic lake]

True. If you are familiar with C++ you can also look the Caliko port to UE4. I have added few notes the original post few days ago to make it work with the most recent engine versions.

It is IK with joint constraints, basically an enhanced FABRIK. Very interesting.

[hushed epoch]

https://forums.unrealengine.com/community/community-content-tools-and-tutorials/108010-ue4-caliko-port-fabrik-with-connected-chains-and-constraints

Very cool, I may look into this

[sonic lake]

You can compile it following the original post + my notes at the bottom.

I think it needs some work to expose an IK node to the AnimGraph, didn't get there with my tests.

[hushed epoch]

That's something I need to figure out anyway 😄

What I am trying to do is do a bit of reverse engineering based on this: https://youtu.be/iYrkXK3V2ik

Basically I got another setup working with a shoulder collision constraint so VR FPS weapons have a third point of contact for stabilization, but I am having some major issues with IKs so I am starting from scratch using the 3rd person character based on your tutorial

They show their VR character rig at about 10:30 into the video

[sonic lake]

Nice project! 👍

[torpid steeple]

I just got an Oculus Rift a few days ago and I finally spent some time doing the basic stuff. It was pretty inspiring!

I wonder how Rec Room manages its Actor replication, considering how it always needs to replicate not only Actor physics but also the individual hands of each player. Their strategy of using minimal Skeletal Mesh bones works pretty well, but I wonder how bad hand Transform replication is per player.

[sturdy coral]

@torpid steeple there are quantization functions to make the transforms take a lot less space (with less precision) and then send them as relative offsets instead of world space

You can also do delta compression where you send them as offsets from last acknowledged position/rotation

[tired tree]

You can also run at lower than the max (90) htz and smooth between updates

depending on smoothing delay it is 1-2 updates behind, but with a decent update speed that isn't noticable

and 30htz is 1/3 the bandwidth cost

I run 1 update behind, meaning that with bad network conditions it is possible that it can have a minor hitch with a delayed packet, but I prefer that over the increased latency of 2 behind like CSGO does

[cunning depot]

@sonic lake Your youtube videos are amazing, ty 😃

[sonic lake]

@cunning depot you are welcome! 👍

[hushed epoch]

Almost got the head -> spine IKs working

Just some very strange stuff happening with the initial head relative offset now which I don't entirely understand 😄

@sonic lake what are you working on these days anyway?

[torpid steeple]

I really don't like how the Oculus app has to pop itself open and steal focus every time I click the "Play" button in the Editor, even when I'm not working on a VR thing.

[hushed epoch]

You just change context

[torpid steeple]

@hushed epoch Do you mean Alt+Tab?

[hushed epoch]

Do you have your Oculus app open or running?

Mine only pops up when you click Play in the Unreal editor and have VR selected in the drop down

If you aren't working on a VR project it shouldn't be selected and therefore not pop up

[torpid steeple]

It's closed, but every time I click Play... even though this is not a VR app and VR is not selected for the Preview, it still pops open the Oculus app.

[cunning depot]

SteamVR pops up everytime I load up UE4 and then again once I open the project, annoying but I deal with it because I don't want to disable the SteamVR plugin 😦

[hushed epoch]

Yeah SteamVR does, but not the Oculus app

But again that's just the SteamVR Status window, I believe you can actually disable that from popping up

Yeah confirmed I disabled it and it no longer opens

[torpid steeple]

It seems like the Oculus eyeball resolution is 450x450, according to UMG?

I imagine this is not standard across devices, though, right?

Actually now that I look closer, I can just barely see down below the squares on the edge of my peripheral vision, so maybe 440 width by 490 height seems about right to properly cover the eyes via UMG.

[sturdy coral]

@cunning depot this will fix that issue:

https://github.com/EpicGames/UnrealEngine/pull/4950

[glass torrent]

Hi everyone!

I'm having a little performance trouble with my map for Pavlov VR (UE 4.15).

Some players are reporting that their machine lags or "hickups" while trying to walk through the forrest area of the map.

Sure enough, the transparent materials on the trees make the Shader Complexity view burn bright-white.

I've changed the materials to use DitherTemporalAA as per the suggestion here -- https://docs.unrealengine.com/en-us/Platforms/VR/ContentSetup

But it's still burning white.

Any tips about:

• how to measure "good enough" in-editor (I don't have any issue while playing, but some players do)
• how to further-optimise these materials?

Thanks in advance!

[candid mountain]

Hi! im using the multi user viewer template, but somehow i can no longer teleport 😮 the beam shows, but just a short one in the hands.. possible solutions anyone?😫

[jaunty shell]

@candid mountain check your colliders in your scene, aswell as your navigation mesh

[candid mountain]

@jaunty shell Thanks for the reply! 😄 i've been doing that, but now i dont know anywhere else to look 😂

[jaunty shell]

havent had much chance with this template so far either :/

I'm using the Product Viewer Template, as it uses a raycast solution instead of relying on the navmesh (we dont have time to do proper navmeshes)

[cunning depot]

@sturdy coral Ty 👌

[candid mountain]

haha.. i dont have time for this neither 😂

[daring pasture]

@tired tree where is the logic for where an object attaches to located? I'm assuming a gripped object attaches to the motion controller? Im trying to attach it to sockets on my characters mesh but cant find it.

[tired tree]

@daring pasture i'll pm you, because no only one grip type actually attaches

[daring pasture]

Ok thank you

[torpid steeple]

@glass torrent are all your foreet trees and stuff separate meshes or are they instanced meshes? Instanced meshes are an aeasy way to fix a lot of shader complexity problems

[glass torrent]

Ooh, good point. They're separate meshes, but that would be a good optimisation!!

[median wedge]

Is there a way to specify to launch through Oculus home instead of steam vr through a command line option?

[sturdy coral]

@median wedge it has a higher priority and will default to it but you can force it with -hmd=Oculus

[median wedge]

Thank you. So if I add that as a steam launch option, it will use the oculus sdk?

[sturdy coral]

@median wedge I think it might be 'OculusHMD' instead of 'Oculus'

you can set the priority in your engine ini

BaseEngine.ini has:

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

whatever has a higher number will be preferred over lower numbers, without that -hmd= option

[median wedge]

Ok. Thank you for all the help

[sturdy coral]

I would leave your steam option without it

and let the priority thing figure it out

[median wedge]

Ok, I will add separate launch options as well in case users want manual options.

But I will also do the priority thing

[sturdy coral]

@median wedge just know if they chose steamvr with oculus, you don't get the same button mappings as oculus via OculusHMD

[median wedge]

What do you mean?

[sturdy coral]

the two buttons on touch are mapped differently with the oculus plugin vs oculus running through the steamvr plugin

[median wedge]

What button?

[sturdy coral]

a and b

[median wedge]

Do they switch?

[sturdy coral]

no, totally different and I think one of hte two isn't even exposed through steamvr by default

and the oculus menu button isn't mapped when using steamvr, because steamvr reserves it as a system button

but also either a or b isn't mapped

[median wedge]

I can test it all when I get my dev kit, and detect and respond appropriately. Thanks for the info

[mighty carbon]

https://uploadvr.com/ces-2019-antilatency-oculus-go-6dof/

neat

[granite jacinth]

...

But it costs more than the GO

I agree it's neat. But sorely impractical. When you can just wait for Quest

Although, I do wonder now, how much the total setup was for the OC5 Dead and Buried demo

[mighty carbon]

oh, $250

yeah, Quest is definitely would be a better investment, especially if average Joe can setup arena for Quest

[sturdy canyon]

Yeah I've been thinking a lot about Quest as a replacement for laser tag

Did you know that typical laser tag vest/gun setups cost like $5k each

Also they are buggy and bad

[mighty carbon]

o.O

[compact kettle]

Hey everyone! I'd be interested to know if there are any efforts alreay being made to integrate foveated rendering techniques into UE4 and whether there are any Dev-Previews scheduled. We would be very interested in picking up / helping to build this technology for the market launch of the Vive Pro Eye HMD. We were at HTC's CES 2019 booth, though without the fov. rendering, and we think it could immensily increase the immersion of our application, if we are allowed to pump up the quality in the focused areas.

[mighty carbon]

This is interesting: https://uploadvr.com/ces-2019-i-streamed-pc-vr-games-to-an-oculus-go-with-tpcast-air/

[harsh cedar]

hey there, is anyone else having issues with billboards only rendering on left eye in 4.21?

[mighty carbon]

RTX 2060 appeared on NewEgg for $349 (sale ends this coming Monday)

[sturdy coral]

@harsh cedar yeah I think I had that many versions back too

I think only with instanced stereo

hmm actually I think back then it may have only been with vrworks

[harsh cedar]

@sturdy coral thats it, but we had it working perfectly in 4.20.3 and the upgrade broke it

https://gyazo.com/89ed3d16b2fe3a0a2f26d9daa60ab8bb

it actually renders in both, but really oddly

the sprite that appears to pan across both is only on right eye

(this is an ordinary billboard)

[wicked oak]

@mighty carbon

[mighty carbon]

what does it mean @wicked oak ?

[wicked oak]

    }
}```

this is the most important chunk

RenderMobileBasePass got completely nuked and replaced with this small one

which uses the ParallelMeshDrawCommand that the desktop renderer uses

i wonder wtf this does

i also havent run it

but that ParallelMeshDraw stuff intriges me

[mighty carbon]

mobile Vulkan?

[wicked oak]

definitely

im going to investigate

[mighty carbon]

interesting

[wicked oak]

     * Dispatch visible mesh draw command process task, which prepares this pass for drawing.
     * This includes generation of dynamic mesh draw commands, draw sorting and draw merging.
     */ ```

@mighty carbon this is batching

its a refactor of the rendering code, everything is no data oriented, multithreaded, and seems like it does autobatching

also automatic instancing

@mighty carbon ``` /**

• Build mesh draw command primitive Id buffer for instancing.
• TempVisibleMeshDrawCommands must be presized for NewPassVisibleMeshDrawCommands.
  */```

without a doubt, automatic instancing

 static TAutoConsoleVariable<int32> CVarMeshDrawCommandsDynamicInstancing(
    TEXT("r.MeshDrawCommands.DynamicInstancing"),
    1,
    TEXT("Whether to dynamically combine multiple compatible visible Mesh Draw Commands into one instanced draw on vertex factories that support it."),
    ECVF_RenderThreadSafe);

ok

get really fucking hyped

becouse this is indeed indirect drawing

[mighty carbon]

hype train is real

[wicked oak]

its actually coyping the render commands to the gpu

into a gpu buffer

[mighty carbon]

do you think it will make it into 4.22 ?

[wicked oak]

yes

[mighty carbon]

sweet

[wicked oak]

im going to try running the dwvr maps

which are super slow

[mighty carbon]

I am guessing they are gearing up for Quest with this

[wicked oak]

and ps5

i wonder if unreal now crunches drawcalls faster

gonna check the rendering behavior

[mighty carbon]

nice, please let us know

[wicked oak]

@mighty carbon it looks (speculation) that its using multithreading to build this batch arrays

and then uploads to gpu

and everything is in super tidy arrays

SoA style, data oriented

which basically translates to "fast"

[mighty carbon]

I'll keep my fingers crossed

[sturdy canyon]

I got confirmation today that the renderer refactor is slated for 4.22

🎉

[tired tree]

physics in 4.21, rendering in 4.22

stable engine - 4.?????

lol, going to be some bugs for a bit

[wicked oak]

its faster

significantly so

holy shit its fast as hell

depth prepass at 0.6 ms on PC

thousand drawcalls

this used to be slower

[mighty carbon]

but what about Oculus Go @wicked oak ?

[wicked oak]

dunno

gonna run it through nsight

get beyond hyped my man

becouse this works

[sturdy coral]

@wicked oak will these improvements only be vulkan/dx12?

[wicked oak]

im going to test dx11

well, i instacrash

rip

lets see vulkan

@mighty carbon nothing says that autoinstancing wont work on mobile

vulkan is really broken

[mighty carbon]

I see

https://uploadvr.com/oculus-android-app-passes-1-million-downloads/

[torpid steeple]

Is the VR Template's implementation of interaction the "proper" way to do it? Specifically, the VR Template's approach seems to just be to attach a collision sphere to the hand and then call an interaction interface function on whatever applicable actor is closest to the hand.

Sounds simple enough but I wonder if the ray-trace approach is better, a la VRChat and RecRoom.

[tired tree]

@torpid steeple I use both, tracing will fail if it starts entirely inside of an object so I fall back to overlap when it doesn't find anything on an attempt.

[torpid steeple]

I'd imagine that making a new Interaction Trace Object Collision channel would be the best way to do implement it?

That way you don't have to worry about your hands getting in the way of the trace or whatever

[tired tree]

yeah, that is my exact setup I used for my examples, a custom trace channel and dual trace / overlap checks

I also have a interface property that lets an ordering happen

IE: more important components / actors are picked out of a grip attempt over less important ones

like sliders on a gun instead of the body of the gun

anything without the interface defaults to lowest priority

[torpid steeple]

One thing I'm having trouble wrapping my head around is the use of Child Actors Components w.r.t Interactable Widgets. I know you probably only want this stuff to be Cilentside, but I remember hearing that Child Actors Components in general are a bad practice, which would imply that having interactable buttons attached together as components in some kind of parent actor, as I've seen in Youtube tutorials, is not good™.

[sturdy canyon]

I'm not convinced that child actors are really bad for MP..

But I only have a few of them around, and I don't attempt to do server/multicast calls directly from them

[torpid steeple]

What I'm trying to brainstorm is how I'd go about trying to implement the Oculus Home UI: just simple, floating panels in front of you that you interact with, and a panel underneath them with buttons you can push down to do things.

The approach I'm thinking of atm is just a single actor with a bunch of individual UMG components for each panel that somehow react to a raycast on clicking a motion controller button, and then using a mesh for the bottom row that has buttons on it and using collision sphere overlaps for those interactions.

In a MP context I'd imagine you'd have to make everything clientside, even the spawning of the Actor... but iirc in MP remote clients can't spawn Actors...

The logistics of this are a bit confusing

[tired tree]

@torpid steeple you can't spawn REPLICATED actors

you can spawn local ones

Can anyone with forward shading experience help me fix this? I have 2 dynamic lights casting shadows in my scene and a planar reflection. For some reason only one of the lights (and shadows) show up in the reflection. I am pretty sure it is because of the dynamic shadow limit but documentation says I should be able to have 4 dynamic casting lights.

Is it bad practice to make a VR game cap its fps to the refresh rate of the headset + around 20 and is this even possible in ue4?

that will be interesting

[candid viper]

Long shot question here. Has anyone seen tracking problems with EV3 Knuckles? Hit issues on a couple of machines where tracking drops out on the controllers and the headset when using them. All firmware updated etc. Been trying all sorts of things. Just interesting if anyone has any off the wall suggestions to try.

[sullen vortex]

after 4 hours of dealing with Mixed Reality calibration tool, found a weird bug on the plugin; i have a logitech c920 camera with a vive tracker attached (see picture),and after doing the calibration process, which showed the final preview that everything was working ok, started my project and previewed in vr, after that i realized that live video and cg didnt match in axis, so i had to rotate the tracker in Z 90 degrees, which is a pain in the ass, cause now i need to design and 3d print a new mount because of this...anyways, it would be great to have the chance to edit in plain text the sav file generated by the calibration tool and fix the orientation...if anybody used this tool and has any idea on how to solve this without building a new rig....

[tired tree]

@sullen vortex there is only one axis that is off

rotate the values you use

but yes, trackers have always been off axis

[sullen vortex]

Cant rotate the values on the config file the calibration tools generates, its not like the config file in Liv

[sullen vortex]

Tomorrow im gonna try redoing the calibration and see if the new file fixes or it repeats the bug. Thanks anyways Morden

does anyone have experience with physics handles? I am trying to make a fixed grip item (pistol, should snap to where the controller is, and face a certain way) but the handle is acting wonkey

[feral bloom]

Dont think you need a physics handle for that. I'd add a scene component above the pistol and set the transforms correctly on that. Then Attach the scene component to the controller

@median wedge

[sage gulch]

can anyone summarize the workflow changes inherent in the compiler message "Set Hand is deprecated; Please use the Motion Source property instead of Hand"? thanks

[sturdy coral]

@sage gulch they switched from an enum to an FName so that non built in plugins could add arbitrary types

[sage gulch]

thanks

[median wedge]

@feral bloom you need a physics handle if you want the items to still simulate physics. I did the other way first, but now I want to maintain physics.

[sonic lake]

@median wedge It is not either/or. You can also attach a skeletal mesh to the hand where the first root bone is kinematic and the rest is simulated. So you still get a physics driven behavior without using a physics handle.

[median wedge]

How do I specify a bone to be kinematic?

[sonic lake]

In the PhAT or by code. You can set the whole SM to be kinematic then use Set All Bodies Below Simulate Physics to set the rest of the skeleton to physics simulation.

https://www.youtube.com/watch?v=O3TM5CL6Eow

[median wedge]

But this wouldn’t work for static meshes I want to keep simulating physics would it?

[sonic lake]

What is the Static Mesh that you want to attach to the hand and why does it need to simulate physics?

I am trying to understand your use case.

[median wedge]

I’m not taking about simulate physics like rag doll, just an object is that simulated, so it can collide and interact with the environment.

[icy berry]

Hi, has anyone here worked with Face AR? Just curious if it works fine with newer models?

Zak mentioned they kinda hard-coded live link for iPhone X at this point. Just what to double check if anyone has used newer iPhones/iPad for it

[tired tree]

@sonic lake @median wedge he is talking about something like this: https://youtu.be/toId0Yhu_U0?t=27

interactible grips that don't push through geometry

and @median wedge how is it acting funky? you didn't specify the symptoms

[median wedge]

It has a strange offset, and the rotation is always different, and irregular.

I am picking it up the motion controllers location, and the objects rotation

I am setting it’s location and rotation with the motion controllers location and rotation.

I set the location and rotation of the mesh to match the motion controller right before I grab, but that does not work consistently for when I am trying to achieve (attach to motion controller with SnapToTarget)

[tired tree]

@median wedge is it simulating when you pick it up already? if so then that would be your issue, set location doesn't play nicely with full simulating

[sonic lake]

@tired tree Yes got it. Is he using your plugin already? Then you are the best person to help on that.

[tired tree]

you can just grip it with the physics handle at the object with a null transform and then move the physics handle to the motion controller

@sonic lake no he isn't, but the basics are mostly the same

physicshandles are generally good enough, just missing some features

[median wedge]

So I should supply null for grip location and rotation? And it is simulating, but I tried without simulating and it didn’t help.

[sonic lake]

@tired tree I didn't play much with physics handles honestly. They are a bit too unpredictable at limit conditions. I prefer more stability over more realism. But for sure they have their application areas.

[tired tree]

i had to go check the handles again as I haven't used the engines one in a while, they are making the rotation and location that you pass in relative to the component, so passing in the components transform values should have it 1:1

then just setting location to follow the motion controller would be like SnappingTo

@sonic lake interacting with physics constraints is far better for some specific applications besides holding objects. Like applying forces to a constrained / simulating construct like a globe or arm light

[median wedge]

Ok. I didn’t know what those values did. Thank you so much for all of your help

[tired tree]

also marco, options never hurt anyone ;p I have 9 grip types in my plugin and have people using all of them afaik, though I don't always agree with how they are used

[sonic lake]

@tired tree wow 9? That's plenty of options to play with.

And I guess someone would still manage to ask for a 10th.

[sullen vortex]

update on mixed reality plugin; did the calibration again, and at the end it shows all stuf correctly aligned, including matching controllers, and after that when i paste the configuration file on the project i get this, wrong axis on the tracker in relation to the camera:

[tired tree]

Its because they are querying the tracker data with the same function as the controllers use

people outside of UE4 have been using an alternate OpenVR function to query tracker poses

seems like they didn't test with trackers as the camera offset? Might want to directly report it on the bugs

its about time they fixed that offset anyway

https://answers.unrealengine.com/questions/744900/htc-vive-tracker-in-unreal.html

people have been just re-mounting for some time now

though that was with a custom solution and not the new official one, its still the same cause

[sullen vortex]

you are right, im doing a custom mount to fix this issue meanwhile, already posted this on the mxied reality sticky post in the official forum

[sullen vortex]

now both cameras are aligned, but it seems i will have to rerun the calibration process, getting hmd and hands offset

[sullen vortex]

update: after redoing the calibration, which at the end always seems to be success, when trying on my project i have offset on my controllers and in the hmd as last intent. Im gonna try doing a project based on vr template and see how it goes

[cunning depot]

Hi, is there a tutorial out there on a pointing-based VR menu? I've made a 3D widget and also implemented an animation for pointing but I don't know how to link the state of when a player points to displaying where the player is pointing with a laser dot and interacting with the menu like simulating "hovering" and "clicking"

[hallow knoll]

@cunning depot https://docs.unrealengine.com/en-us/Engine/UMG/UserGuide/WidgetInteraction

[cunning depot]

I see, thanks @hallow knoll!

[hallow knoll]

Np! It might be worth mentioning that UMG buttons are "Press and release" click method by default, if you have small buttons it's sometimes worth changing it to "Press"

As for the "laser trace" there's a default laser static mesh that's used for the VR Editor that you can use, it's under Engine Content

Data from a separate line trace can be used to scale that mesh

[cunning depot]

I see, ty again 😄

[hallow knoll]

Np, now if you could return the favor and help me organize my office, that'd be great

[cunning depot]

LOL once my game's released I'll use a cut to fly over and get on that asap

[hallow knoll]

Is there a way to disable the damn oculus app and Steam VR from launching when I open my project

@real needle Oculus App no, unless you revert to an old 1.0 core which someone has backed up and shared (search on Reddit). Cannot talk for SteamVR since I don't use it.

[charred hinge]

hey

im working on a vr shooter and im at the point of trying to sync my character mesh to my vr movements. wondered if anyone could give me some tips

what exactly is the vr origin? is it the location of the headset? the location of the ground beneath the headset?

should my mesh be attached to the vr origin?

actually yeh the origin is the headset position, i see now

[feral bloom]

I'd strongly recommend this plugin https://forums.unrealengine.com/development-discussion/vr-ar-development/89050-vr-expansion-plugin

Will make you life a lot easier @charred hinge

[charred hinge]

id rather do it myself:)

[feral bloom]

Fair go, well in my game i'm using ikinema for a full body ik rig but the headset position drives the location of the skeletal mesh. Takes a bit of work in anim blueprint to make it feel like a character moving around and not just a levitating mesh attached to your chin

[charred hinge]

yeah i was thinking of aligning the character mesh below the headset and driving the anim blueprint with the headset height and direction

thing is, i cant find how to get the headset height

[feral bloom]

Should be the location of the headset minus the location of the pawn right?

That's how it is for Vive anyway

[charred hinge]

wouldnt that be the half height? at least for a character

[feral bloom]

I usually set 0,0,0 as the bottom of the character/capsule

[charred hinge]

oh, i didnt know you could do that with the capsule component

its center is always at 0, 0, 0, and since its the root i cant move it around

is it a specific setting somewhere, i cant seem to find anything

or do you not have it as the root component and manually move it up?

[feral bloom]

Sorry not entirely sure. I'm using a plugin class where it is defaulted that way, cant find a setting

Is yours a character class?

[charred hinge]

yeah

[feral bloom]

Can't find anything helpful. It's possible it's not exposed in blueprints and the VR expansion plugin has sorted it all behind the scenes. Hopefully someone else chimes in

[charred hinge]

is there no way to access the physical headset height in the real world?

how does that plugin handle leaning btw?

does it allow you lean left and right while somehow keep your characters feet in the correct place?

[feral bloom]

The plugin is more of a general VR one, it doesn't have a rigged VR body. To get that functionality you'd have to set it up yourself and give some kind of buffer for leaning before moving

The height in unreal should be the same as the real world. So just double your half height and you have it.

[tired tree]

@charred hinge @feral bloom my plugin character is 0,0,0 centered as it makes the most sense for VR, your virtual offset is your camera position. However with the base ue4 VR setup using a character 0,0,0 is at the half capsule height location.

you'll also run into an issue in that the actual HMD location is offset from the zero point, which is why they have you add a VR root

when you walk around in room scale you are walking around your capsule which stays in place, to really get accurate collisions with the character movement you either need to move the character with the hmd movements, offset the capsule to match it, or run two actors, one for the VR components and one for the character that mirror each other.

and yes, the Camera height == your height unless WorldToMeters != 100.0f or you scaled the pawn base

but you can sample the hmd directly as well with some nodes

also no you can't move the root component around in local space normally (used to be able to back in the very beginning but it got deprecated). I am doing that manually with some overrides in the back end.

[dusky moon]

Have you guys noticed there's a section in FB dedicated to Oculus ?! (on the left bar ...)

just a bit of motivation that it's still alive hehe

[median wedge]

does anyone know how to prevent to crash of the game when steamvr exits? I would prefer for my game to exit quietly

[charred hinge]

@tired tree just got back and saw your messages. Thanks for the info

I was actually thinking of putting the vr components in their own pawn and having another paw/character to represent the player as i need to mix user input with an ai controller too

Vive users: How do people generally refer to the 4 buttons mapped to each controller? Up/down/left/right?

Since UE 4.19 Post Processing Materials are rendered on each eye separately, is there a way to override this in 4.21 to the previous functionality? My post processing material for blinders when moving now render in each eye separately after upgrading versions

[runic phoenix]

need vr rendering help... I have some UMG widgets that I render on widget components in 3D space, but the text is really noisy on the Rift - looks like there are no mip maps and no easy way to enable them. Is there a better way to render them for VR?

I saw the reprojection layers thing but that seems to be primarily for head-locked things. These widgets can be occluded

[sturdy coral]

@runic phoenix they are drawn each drame so no mips, if you are using TAA it can handle mismatched mip levels better.

another way is to manually supersample in the UI shader

[sonic lake]

@runic phoenix could also be a scalability setting

Had this once in a packaged experience where texture became blurry. Had to force TextureQuality to the max.

[runic phoenix]

it isn't blurry, it is a sub resolution thing

for example straight lines become dashed lines as the angle rotates vs the main frame buffer

right now the UMG widget has a retainer at the root so it renders the whole thing to a texture (which only re-renders on invalidate) and then that gets rendered onto a world-space quad every frame by way of the widget component

need this to work on Android so I think TAA is out 😦

I wonder if I can get access to the widget component's shader, that is a good idea

[sturdy coral]

if you need it to work on android it will probably be hard to get it performant

@runic phoenix there is a umg retainer box or something that lets you render a widget to a texture, you could then render that texture to a power of two lower, and repeat, to generate sort of manual mips on GPU (there might already be a function for that somewhere)

no anisotrophic mips with that though

[runic phoenix]

I was hoping to find a solution that wasn't so manual

but yeah that might be what I need to do

I'm using the retainer already

[sturdy coral]

there are ways to generate a mip chain on the gpu, hzb uses that, but I don't know if it is anything standardized

and hzb uses a min or max sampling as it downscales instead of an average

[icy berry]

Hi, has anyone worked with Face AR one new ipad pro?

[abstract panther]

So if I wanted to get a different menu depending on what you hit how would I do it here ? Like is it possible to connect different arrays ? Or is this something you need to do at the blueprint actor of the object ?

[sly elk]

does unreal have any built in functionality to do brows the desktop in game?

@sly elk for file browsing?

there is some open file dialog stuff but it uses the native windows dialog so doesn't work in VR, I need some file stuff for VR too

hey what can I add to the object of my cast to gun base?

the only thing I know how to cast to is the pawn because I have seen it done many times before

@quiet swan typically you cast the pawn to make it a specific one or an actor/component as result of a collision/overlap to identify what triggered it. In this case what are you trying to achieve?

Is there a trick to getting the raw finger values from SteamVR as input? I've been working through the current state, have buttons/thumbstick working fine but I'm not having any luck with the finger inputs. They show up in the Steam VR input debugger - for example /input/finger/index, but everything I've tried shows up in the actions list as unbound.

[tired tree]

@candid viper are you using the legacy inputs?

or the beta

[candid viper]

The beta - vr.SteamVR.EnableVRInput=1

[tired tree]

Then you'll need to add inputs in editor to bind too

that being said, you can also query the finger curl / splay directly and get a list

[candid viper]

In my knuckles.json, I have things like:

{
"inputs" : {
"position" : {
"output" : "/actions/main/in/leftknucklesjoyxtouchjoyyaxis_axis2d"
}
},
"mode" : "joystick",
"path" : "/user/hand/left/input/thumbstick"
},

That bins fine.

Binds, sorry.

{
"inputs" : {
"position" : {
"output" : "/actions/main/in/leftknucklesindex_axis"
}
},
"mode" : "pull",
"path" : "/user/hand/left/input/finger/index"
},

But anything like that for the fingers I get nothing.

Querying finger curl direct would work though. Thanks

[tired tree]

I think most of those curl inputs were for the V1 knuckles

they seem to have moved away from it

I know the engine bound to them prior to the new input system with V1

and it wasn't working with later versions

I didn't try and get them working since the curl values exist

[candid viper]

Okay. Where are the curl values? (Just to save me time looking)

I missed them when looking initially.

[tired tree]

the skeletal api has it for the pose

the original binding though was:

            indexCurl = Controller.GetAxis(EVRButtonId.k_EButton_Axis3).x;
            middleCurl = Controller.GetAxis(EVRButtonId.k_EButton_Axis3).y;
            ringCurl = Controller.GetAxis(EVRButtonId.k_EButton_Axis4).x;
            pinkyCurl = Controller.GetAxis(EVRButtonId.k_EButton_Axis4).y;

axis 3 and 4

x and y

[candid viper]

Great, thanks. Since the inputs still show in the SteamVR Input debugger, I wanted to just bind to them

[tired tree]

const FGamepadKeyNames::Type SteamVR_Knuckles_Left_PinkyGrip("SteamVR_Knuckles_Left_PinkyGrip");

was this the one you were trying to use?

[candid viper]

Unbound on the left, inputs on the right. May well be they're just not going to keep them exposed

No, I've been trying to fully use the new SteamVR bindings

[tired tree]

yeah but that is why they are unbound

the editor still writes them out

you can't add input_finger_index ect to them?

[candid viper]

Ah, I thought they just needed "a" bindUE4 side - I have the index finger bound to MotionControler (R) Trigger as that was a known valid one. I thought that was then ignored

[tired tree]

You need to set up default bindings

I can't load up the binding ui right now as I am not near my headset, so sorry been trying to work from memory :p

[candid viper]

This is my current default in UE.

I don't see a binding UE4 side that I can use. Thanks for the help - very much appreciated, working from memory or not.

UE4 has generated the steamvr_actions.json

{
"name": "/actions/main/in/LeftKnucklesIndex_axis",
"type": "vector1",
"requirement": "optional"
},

The bindings I have working I did SteamVR side using the controller binding tool. I tried manual json first, with no luck. Now, they work, but when trying to get the fingers I get the feeling I have something off in the path, or similar but haven't managed to figure out what.

[tired tree]

its easier to use their tool and then export it

and use that export as the default

if you enable developer mode it lets you save it out

[candid viper]

That is what I've been trying to do, but I don't understand how to setup the fingers. Thumbpad/trigger were fine.

That's what I have right now - Steam VR beta 1.2.8

[tired tree]

oh I see

so you are trying to manually bind it

since the UI is missing the input
