#

supposedly if you add some temporal filtering it gets a lot more compressible

glossy agate Jul 13, 2018, 4:30 PM

#

Oh yeah, since you were doing that hologram stuff, you should try setting up a camera and see if you can use that new Ai stuff from facebook to get real external full body tracking

sturdy coral Jul 13, 2018, 4:30 PM

#

I am quantizing it a lot which makes it better

#

but it can be really noisy especially on dark colors that it doesn't get a good IR bounce from

tired tree Jul 13, 2018, 4:30 PM

#

temporal filtering would make sense, you really want it to be density culled

#

and that would be a fast method of it

sturdy coral Jul 13, 2018, 4:31 PM

#

you can use the IR view to see which areas will likely have the most noise

#

and temporally filter them stronger than others

tired tree Jul 13, 2018, 4:31 PM

#

you can also pick the focal point and trash everything outside of a boundry box

sturdy coral Jul 13, 2018, 4:32 PM

#

focal point like the player?

#

I'm using the body indexing stuff to only send the player

tired tree Jul 13, 2018, 4:32 PM

#

ah

granite jacinth Jul 13, 2018, 4:45 PM

#

@sturdy coral if you get it to a good enough state, consider plugin -sell on MP

#

You'll easily make quite a bit from it

mighty carbon Jul 13, 2018, 4:52 PM

#

I wonder how many UE4 devs dig VR nowadays.. I'd like to try making some assets for MP and see I can get some supplemental revenue to fund my projects.

glossy agate Jul 13, 2018, 4:59 PM

#

What kind of assets?

#

And ditto what victor said. I would like spatial audio on top of team channel so you have to be carful about talking near enemies

sturdy coral Jul 13, 2018, 5:00 PM

#

@granite jacinth not sure i could do it all as a pure plugin without copying the existing steam one, but I guess you are allowed to bring in engine code on marketplace stuff as long as it isn't from the editor folders (for a non-editor plugin)

#

they messed up the implementation a bit where it won't be easy to do both radio and spatial simultaneously

#

at least as a plugin, that will require some engine changes

glossy agate Jul 13, 2018, 5:02 PM

#

Yeah. I guess what I have is fine for now. Same setup as R6S. Just have to listen for footsteps, reloads, slide racks ect for position

fleet plume Jul 13, 2018, 5:35 PM

#

@wicked oak you don't use behaviour tree movement functions, but still use regular character controller for enemy AI's right?

wicked oak Jul 13, 2018, 5:35 PM

#

yes

#

and im going to fully reimplement path following

fleet plume Jul 13, 2018, 5:36 PM

#

how many can you use at once?

wicked oak Jul 13, 2018, 5:36 PM

#

becouse current implementation is shit

#

it depends on how complex the skeletons are

#

now that i have optimized their components, its better

#

remember moving objects trigger all sorts of physics recalculations

fleet plume Jul 13, 2018, 5:37 PM

#

what do you mean with components? regular cmc or something else?

wicked oak Jul 13, 2018, 5:37 PM

#

meshes/subactors

fleet plume Jul 13, 2018, 5:37 PM

#

damn, need to read up on that

#

i guess the ue4 mannequin is also a good place to start looking at the setup, right?

mighty carbon Jul 14, 2018, 1:06 AM

#

@glossy agate models / anims most likely. Maybe textures. Probably non-PBR style for anything at this point.

sturdy coral Jul 14, 2018, 2:03 AM

#

another problem with Oculus via steamvr:


                        // If the touchpad isn't currently pressed or touched, zero put both of the axes
                        if (!CurrentStates[ ESteamVRControllerButton::TouchPadTouch ])
                        {
                             VRControllerState.rAxis[TOUCHPAD_AXIS].y = 0.0f;
                             VRControllerState.rAxis[TOUCHPAD_AXIS].x = 0.0f;
                        }

doesn't work well with touch controllers because you can move the joystick without hitting cap touch pretty easily

#

changed it to:

// Device has a joystick treated as touchpad, like Oculus Touch
                bool bIsTouchpadReallyAJoystick = VRSystem->GetInt32TrackedDeviceProperty(DeviceIndex, static_cast<vr::ETrackedDeviceProperty>(vr::Prop_Axis0Type_Int32 + TOUCHPAD_AXIS)) == static_cast<int32>(vr::k_eControllerAxis_Joystick);```

```cpp
                        // If the touchpad isn't currently pressed or touched, zero put both of the axes
                        if (!bIsTouchpadReallyAJoystick && !CurrentStates[ ESteamVRControllerButton::TouchPadTouch ])
                        {
                             VRControllerState.rAxis[TOUCHPAD_AXIS].y = 0.0f;
                             VRControllerState.rAxis[TOUCHPAD_AXIS].x = 0.0f;
                        }```

@full junco @tired tree ^

#

can't remember who else is doing at least some oculus via steamvr stuff, @granite jacinth maybe?

granite jacinth Jul 14, 2018, 2:12 AM

#

Aye. Looks nice. Never had that issue before.

sturdy coral Jul 14, 2018, 2:13 AM

#

you'll definitely want to set a deadzone if you do that though

#

but you can do that outside of the plugin on the axis properties

#

(native rift plugin doesn't check for touch either and also needs a deadzone)

#

@granite jacinth someone has put up a pull request for WMR joystick support if you need that:

#

https://github.com/EpicGames/UnrealEngine/pull/4874

granite jacinth Jul 14, 2018, 2:16 AM

#

Ah nice. Yeah. I need to do another pass on WMR

sturdy coral Jul 14, 2018, 2:18 AM

#

I think maybe @sly elk was looking for that too

#

his PR hardcodes it in a way that isn't great, without actually querying the type of the axis

#

but I think it should be ok for all existing controllers

broken moat Jul 14, 2018, 8:28 AM

#

anyone know how to give the player an item belt in vr?

sturdy coral Jul 14, 2018, 3:33 PM

@broken moat you can look at robo recall holsters

alpine aurora Jul 14, 2018, 6:22 PM

#

Im curious why there's so few VR apps that let you control a steering wheel with motion controllers

#

Is it a difficult/tedious interaction to program or something?

tired tree Jul 14, 2018, 6:49 PM

#

it doesn't feel that good

#

there isn't any 1:1 interaction with a two handed wheel

#

it has to be aproximated

#

I prefer 1 hand on the wheel and 1 hand doing something else personally

alpine aurora Jul 14, 2018, 7:00 PM

#

What if you just didn't parent your grips to the wheel transforn

#

And used the min of the two rotational deltas?

alpine aurora Jul 14, 2018, 7:35 PM

#

also, are there any games with a motion controller -> steering wheel control scheme?

tired tree Jul 14, 2018, 7:40 PM

#

that is what I meant

#

its not 1:1

alpine aurora Jul 14, 2018, 7:42 PM

#

i know exactly what you meant, I just don't see why it can't be 1:1 if you decouple the grip->wheel transformations

wicked oak Jul 14, 2018, 7:43 PM

#

im going to pass the time in a travel with my oculus go, watching sword art online movie

#

meta

#

i want to see how the device works when you are in a car

alpine aurora Jul 14, 2018, 7:43 PM

#

ie, grip movement along the wheel shouldn't be coupled directly to the steering wheel transform

#

it should only control the position of the grip rendered onto the wheel

#

wheel transformation gets applied indirectly, and from the minimum of the two grip rotations

#

i don't see how that wouldn't be 1:1

mighty carbon Jul 14, 2018, 7:53 PM

#

@wicked oak you aren't the driver, are you? 😛

wicked oak Jul 14, 2018, 7:53 PM

#

no

alpine aurora Jul 14, 2018, 7:54 PM

#

he is

#

he has a panoramic camera installed on the top of his car fed into his hmd

#

it's like he's driving his card in third person view

wicked oak Jul 14, 2018, 7:54 PM

#

nvidia showed literally that

#

a vr driver driving a real car

#

the driver was on the showfloor, and the car drove around the real street with no driver inside

#

thats going to be a important step for the "ai fleet" cars

#

you have a bunch of drivers on a call center wich take over the car in the case there is something weird going on

#

im also putting the extended lord of the rings triology on the Go

#

pretty sure battery wont last one of the movies

#

they are like 3 hours 20 minute each

#

holy shit return of the ring is 4 hours

tired tree Jul 14, 2018, 8:13 PM

#

@alpine aurora because your hands aren't actually locked there

#

unless you literally move them at the same speed around the circumference of the wheel its not 1:1

#

you can do it

#

there are games that do

#

I just don't prefer it

alpine aurora Jul 14, 2018, 8:14 PM

#

do you have names of any games with 1:1 steering wheel motion?

tired tree Jul 14, 2018, 8:17 PM

#

not off the top of my head, there are more than a few

alpine aurora Jul 14, 2018, 8:18 PM

lots of the lesser known games on steam with cars do it

I'm trying to run through the oculus go setup documentation and I can't get the Oculus Go controller to work. I assign a "motion controller" component and then a static mesh to that for visual verification. But when I launch to the Go Only the Go HMD functions as expected, the controller doesn't move at all when I move it around.

never tried it directly, but had a BP as a child actor in there that acted like a gripable mesh

broken moat Jul 16, 2018, 12:02 PM

tired tree Jul 16, 2018, 12:09 PM

#

you are trying to attach a skeletal comp

#

you need to implement the interface of epics on it

#

their default is to attach a full actor

#

you can totally attach a component

broken moat Jul 16, 2018, 12:10 PM

#

which interface?

tired tree Jul 16, 2018, 12:10 PM

epics pickup interface?

but from that SS above, it looks like you wanted additional data, like a slicing plane

#

so yeah, an actor is what you need

broken moat Jul 16, 2018, 12:11 PM

it still doesnt allow me to grab the sword

eager pine Jul 16, 2018, 12:35 PM

well, my real issue is this tough maybe i can get some help around it

#

soz i have a skeletal mesh in my vr character, that has two bones named left_socket and Right_Socket, which i added inn an array

#

Based on the index passed in it will choose between which to get from the arraya

#

📎 unknown.png

#

now, with index 0, it seems fine, everything works, the actor is hanging

#

📎 unknown.png

#

thats for the cable end

#

but, when 1 index is passed inn, the skeletal mesh actors that is constrained is jumping around in an axis at 0,0,0

#

Now the name is correct, and i dont understand why the first one constrains, but not the second index

but I dont see why it couldnt just be on the unreal marketplace like the other plugins

tired tree Jul 16, 2018, 3:09 PM

the default / master branch is the current engine version

and it is a free open source plugin that gets constant updates

marketplace can't keep up with it

not all plugins are on the marketplace fyi

trying to port back features to old engine versions while maintaining it on the marketplace would be hell

that is a better starting out plugin anyway

are you attaching to a character capsule component?

placid rampart Jul 16, 2018, 6:10 PM

#

i have a scenecomponent that i'm using as VRRoot that is attached to the character capsule

#

and my camera is attached to the VRRoot

sturdy coral Jul 16, 2018, 6:10 PM

#

you have to set the headset in floor origin mode

#

and put the VR root at the bottom of the capsule

#

put it at the center then in constructor or at beginplay move it down by subtracting result of scaled capsule half height node

#

tracking origin is the other node

placid rampart Jul 16, 2018, 6:11 PM

#

Thanks! i'm gonna try this out now

#

Those changes are valid only for the rift?

sturdy coral Jul 16, 2018, 6:12 PM

#

oculus and vive have different default origins

#

as long as you set it to floor both will be the same

#

vive defaults to floor, oculus defaults to whatever the hmd was calibrated to (like in cockpit games)

placid rampart Jul 16, 2018, 6:12 PM

#

Oh ok, i thought i was going to do a hmd check

sturdy coral Jul 16, 2018, 6:12 PM

#

but both can be set to floor and then should act the same

placid rampart Jul 16, 2018, 6:13 PM

#

Okie, thanks

sturdy coral Jul 16, 2018, 6:13 PM

#

then yeah make sure your VRRoot is actually on the floor

#

you may want to take off an extra inch below the capsule bottom, because character movement component keeps it a bit off the floor

placid rampart Jul 16, 2018, 6:14 PM

#

I'm gonna set the VRRoot Z location at the constructor

#

VRRoot->SetRelativeLocation(FVector(0.f, 0.f, GetCapsuleComponent()->GetScaledCapsuleHalfHeight() * -1));

sturdy coral Jul 16, 2018, 6:15 PM

#

yeah maybe take off 2

CMC uses:

const float UCharacterMovementComponent::MIN_FLOOR_DIST = 1.9f;
const float UCharacterMovementComponent::MAX_FLOOR_DIST = 2.4f;

#

so the capsule hovers 1.9-2.4cm off the floor

placid rampart Jul 16, 2018, 6:15 PM

#

Didn't know that

#

thanks

sturdy coral Jul 16, 2018, 6:15 PM

#

yeah even that small amount can be noticable with picking up objects and stuff

#

though you should probably always have a little bit of magnetism for that kind of thing to where it wouldn't matter

#

WindowsMR seems to get the floor wrong and a lot of users of it don't fix it

Hey, anyone have pointers on getting 3d assets looking good at around the 2000 cm range? Is the mesh resolution the main factor? Not sure what the main cause of this blurriness is.

mighty carbon Jul 16, 2018, 11:31 PM

#

TAA

#

(perhaps)

west atlas Jul 16, 2018, 11:36 PM

#

I'll try it. Had it on MSAA and it wasn't any better than default.

mighty carbon Jul 16, 2018, 11:39 PM

#

I mean, if you have forward rendering and MSAA, it should be sharper than deferred + TAA.. That's with default screen percentage settings.

#

also, anything at the distance will look blurrier than up close..

#

physical screen res isn't that great, plus textures are mipmapped and you have SDE playing tricks too

west atlas Jul 16, 2018, 11:44 PM

#

I had forward rendering and msaa ... for some reason my stuff was blurry at a distance but crisp up close

#

Ugh, lagging from recompiling shaders. Would mipmapping make the entire model look more blurry though?

#

SDE?

mighty carbon Jul 16, 2018, 11:46 PM

#

screen door effect

west atlas Jul 16, 2018, 11:46 PM

#

Would a lower resolution model look worse further away than it would up close?

#

it's pretty low poly

mighty carbon Jul 16, 2018, 11:48 PM

#

perhaps you can post comparison screenshots here to show what you mean by "blurry" exactly ?

west atlas Jul 16, 2018, 11:49 PM

#

Yeah, might be a few. I have 3000 shaders left to compile. It looks more blurry than your standard SDE I'd say, but I'll try to capture it for ya.

west atlas Jul 17, 2018, 12:04 AM

#

I don't know... maybe it is just the screen door effect. I feel like I've seen things look more crisp than this at this distance.

📎 unknown.png

mighty carbon Jul 17, 2018, 12:07 AM

#

why don't you put some of them close to the cam and some in between closest and farthest objects. Also place some other model (a few UE4 cubes) next to those far away objects.

#

you don't have any reference points there, so it's really hard to say why it's blurry

#

do you have DOF on ?

west atlas Jul 17, 2018, 12:10 AM

#

Ok I'll toss in some for reference... this is what they look like up close just fyi. And what is DOF?

📎 unknown.png

mighty carbon Jul 17, 2018, 12:13 AM

#

lol

#

that's not what I was asking for

#

DoF is Depth of Field

sturdy coral Jul 17, 2018, 12:18 AM

#

unchecking it just means that one won't override the base

#

@west atlas try the VR template and see if things look better from far

#

you can disable dof through pp settings but it can be a pain

mighty carbon Jul 17, 2018, 12:19 AM

#

everything looks blurry :/

#

as if AA blurs everything

sturdy coral Jul 17, 2018, 12:20 AM

#

@west atlas you can try r.DepthOfFieldQuality 0 on the console to see if that is the issue

#

oculus rift, nvidia gtx 1070

sturdy coral Jul 17, 2018, 12:22 AM

#

have you tried robo recall and other UE4 forward rendered stuff that uses MSAA?

#

and does that stuff look blurry to you too?

west atlas Jul 17, 2018, 12:22 AM

#

yeah robo recall looks sick

#

no, not like this

#

i'm wondering if i just need more vertices in the mesh

sturdy coral Jul 17, 2018, 12:24 AM

#

@west atlas I think I see your problem

#

the pins seem to have geometry for the stripes

#

are they connected in UV space to the rest of the pin mesh, or are they separate islands?

west atlas Jul 17, 2018, 12:25 AM

#

They are separate material layers, but I didn't touch UVs on this. Just doing a quick prototype to figure how to go about models and textures for vr

sturdy coral Jul 17, 2018, 12:25 AM

#

if they are separate islands, you aren't going to benefit from mip mapping around them, geometry doesn't downsample in the same way as textures

west atlas Jul 17, 2018, 12:25 AM

#

So yeah, separate islands

sturdy coral Jul 17, 2018, 12:25 AM

#

you'll end up with just the MSAA samples around the edges of the stripes, 4 samples per pixel

west atlas Jul 17, 2018, 12:26 AM

#

Hmm, would disabling mipmapping possibly fix it? I don't think I'll need aggressive mipmapping at least to start.

sturdy coral Jul 17, 2018, 12:27 AM

#

no, I think the problem is you aren't getting real mip mapping

#

so you are essentially relying on tiny geometry features that won't hold up well in the distance

west atlas Jul 17, 2018, 12:27 AM

#

let me check the textures that came in from maya

sturdy coral Jul 17, 2018, 12:27 AM

#

one thing you can do is just bake a lod with the new mesh simplifier

#

it will bake it down into a simplified mesh with a generated texture that should mip fine

#

you can't do subpixel details with geometry very well

west atlas Jul 17, 2018, 12:28 AM

#

Oh yeah, I forgot... these are not even using texture samples... Just materials each with a simple red/white base color.

sturdy coral Jul 17, 2018, 12:29 AM

#

yeah same issue

#

if choosing the materials is based islands of geometry

#

then you aren't going to get good results when it gets down to distances where the features are in the subpixel regime

west atlas Jul 17, 2018, 12:30 AM

#

so are you referring to this "Bake out materials" from the sm editor?

sturdy coral Jul 17, 2018, 12:32 AM

#

@west atlas no, let me see what it is named

#

@west atlas but think of it like this: where the red meets the white, without AA you would only get a stair stepped line inbetween. As the red got to the point where it was smaller than a pixel you would just get some random pixels near it

#

with 4x MSAA it is the same thing, just with the edges sort of supersampled

#

where red meets white you will either have 1, 2 3 or red subpixels downsampled into 1

#

so only three levels of gradiation along those edges

west atlas Jul 17, 2018, 12:36 AM

#

ah

sturdy coral Jul 17, 2018, 12:36 AM

#

whereas with mipmap sampling of the region it is prefiltered

west atlas Jul 17, 2018, 12:36 AM

#

Wait so -- I could alleviate this by simply importing proper textures right?

sturdy coral Jul 17, 2018, 12:36 AM

#

you could have 256 levels of variation or more depending on textures and bit depth of output

#

@west atlas yeah, but having the textures laid out in a UV map where the red stripes are adjacent to the white pin

#

if they are separate islands in the UV map you will get no benefit

#

I think the auto lod generation might just use your existing textures

mighty carbon Jul 17, 2018, 12:40 AM

#

it doesn't look like a texture issue though

#

look at the cubes - edges are blurry

west atlas Jul 17, 2018, 12:43 AM

#

The cube edges dont look as bad inside the headset, the pins after a certain distance almost look like they switch to a billboard or something

#

New UVs... Let's give this a try

📎 unknown.png

mighty carbon Jul 17, 2018, 12:45 AM

#

I'd make a plain color texture and test with that - I think something is going on with geometry rather than textures

west atlas Jul 17, 2018, 12:48 AM

#

Yeah, I noticed my smoothing groups weren't imported with the obj for some reason. I'll double check the import settings.

mighty carbon Jul 17, 2018, 12:48 AM

#

that has nothing to do with blurry contours

west atlas Jul 17, 2018, 1:04 AM

#

I think the pins look a little better now that I remembered to export with smoothing on. What would cause moving jaggies around the edges of the cubes?

west atlas Jul 17, 2018, 1:23 AM

#

yeah pins look like I'd expect now

📎 unknown.png

mighty carbon Jul 17, 2018, 1:24 AM

#

I still have a feeling you are running TAA instead of MSAA

#

(although I haven't worked with Rift for some time and in Go everything looks sharp enough)

west atlas Jul 17, 2018, 1:48 AM

#

I'm using MSAA

#

When I turn my msaa count up i get the jagged edges on the boxes as you can see there. And this one below is with r.MSAACount 0

#

📎 unknown.png

glossy agate Jul 17, 2018, 2:10 AM

#

Is that your uv for the whole pin? That round picture?

sturdy coral Jul 17, 2018, 2:10 AM

#

@west atlas MSAACount 0 activates TAA

glossy agate Jul 17, 2018, 2:11 AM

#

If it is that is really not how you want to UV an object

sturdy coral Jul 17, 2018, 2:12 AM

#

Count 1 is no msaa, and Count 4 I think is the max (beyond that no added effect)

west atlas Jul 17, 2018, 2:19 AM

#

@glossy agate Yeah I'm aware those aren't ideal UVs hahaha. It's working ok though since it's basically a solid color with no fine grained detail. I'll have to go back and do it right if I plan on adding scratches, etc.

glossy agate Jul 17, 2018, 2:20 AM

#

Ah ok. Was gonna say right where your stripe is supposed to go Its super cramped so that may be part of the issue

west atlas Jul 17, 2018, 2:21 AM

#

@glossy agate Do you know how to successfully unwrap a sphere? 😛

#

(I'm on to the bowling ball part) -- this was a nightmare last time I did a skydome

glossy agate Jul 17, 2018, 2:24 AM

#

I use max and there is a sphere unwrapper tool. For stuff like human heads. You can probably just do a left/right unwrap and flatten it out though cause it’s simple

west atlas Jul 17, 2018, 2:24 AM

#

Hmm seems splitting the sphere in half and doing a planar projection works as you'd expect

glossy agate Jul 17, 2018, 2:25 AM

My rule of thumb is the vive, although at that price in the UK I'm not sure if you can find new ones

the rift is too much of a hassle to setup for roomscale tracking imo

#

even if its cheaper

if you can import a Samsung Odyssey from the USA that's also a good option

if you want to move your playspace a lot go for Windows Mixed Reality devices

this is the quickstart for unreal and steamVR btw

terse moon Jul 18, 2018, 11:19 AM

#

Awesome! Thanks 😄

mighty carbon Jul 18, 2018, 11:19 AM

#

Lol, get Rift

#

Seriously

jaunty shell Jul 18, 2018, 11:20 AM

#

oh no not you :p

#

right so you had the Vive user pov, now you will have the Rift user pov

#

that way you can balance your choice

terse moon Jul 18, 2018, 11:21 AM

#

Okay I'm waiting to hear the pitch 😃

mighty carbon Jul 18, 2018, 11:21 AM

#

I just woke up 😂

jaunty shell Jul 18, 2018, 11:21 AM

#

😄

mighty carbon Jul 18, 2018, 11:22 AM

#

So, ask questions and I'll try answering

#

Unless you are dead set against Oculus and Facebook. Then no pitch will change your mind.

terse moon Jul 18, 2018, 11:23 AM

#

Iv used oculus in the past at university and i have facebook

#

I have an open mind, i just wanted to know which was the best for development on unreal

wicked oak Jul 18, 2018, 11:25 AM

#

its oculus by a massive difference

#

much better software, and you dont have to deal with steamvr

#

plus its a lot easier to put on-off

#

you also have official ue4 builds by oculus,wich have the absolute latest fancy stuff

jaunty shell Jul 18, 2018, 11:27 AM

#

you do have to deal with the oculus software

wicked oak Jul 18, 2018, 11:28 AM

#

nowhere even close to as bad as steamvr

#

steamvr fucking with the audio gets me every time

jaunty shell Jul 18, 2018, 11:28 AM

#

I dunno I never really had some issues with steamvr

#

have you changed that in the audio parameters ?

#

the output switch

wicked oak Jul 18, 2018, 11:29 AM

#

yes

jaunty shell Jul 18, 2018, 11:29 AM

#

what bothers me the most with the rift is the multiple camera setup and the fact that facebook owns them

#

I'm fine with the rest

#

its a good headset

terse moon Jul 18, 2018, 11:33 AM

#

So it boils down to the cameras and practicality for myself as they both have pros and cons

jaunty shell Jul 18, 2018, 11:34 AM

#

basically how do you want to setup your VR space and what kind of software experience do you prefer

terse moon Jul 18, 2018, 11:35 AM

#

Which is the easiest 😂

mighty carbon Jul 18, 2018, 11:38 AM

#

From consumer perspective, with Rift you can play both Steam and Oculus games natively.

#

Customer service and dev support are better with Oculus

wicked oak Jul 18, 2018, 11:39 AM

#

and software is better. ASW and all that stuff

#

also bit higher resolution on the center (but lower fov)

jaunty shell Jul 18, 2018, 11:40 AM

#

yeah pixel density is a tad higher on the rift

wicked oak Jul 18, 2018, 11:40 AM

#

i have both, and once i got my rift i never plugged the vive again unless i needed to test if stuff works

mighty carbon Jul 18, 2018, 11:41 AM

#

Also Oculus paid for hotel and passes for OC5 for Start members and gave free hardware

#

Touch controllers are far better than wands

jaunty shell Jul 18, 2018, 11:41 AM

#

well we do have the knuckles coming

#

which are better than the touch controllers

mighty carbon Jul 18, 2018, 11:42 AM

#

But they aren't available for most yet

jaunty shell Jul 18, 2018, 11:42 AM

#

but yeah the wands are so so

wicked oak Jul 18, 2018, 11:42 AM

#

so much free hardware

#

jesus stop

mighty carbon Jul 18, 2018, 11:42 AM

#

So it's still wands vs Touch

wicked oak Jul 18, 2018, 11:42 AM

#

literally dont have the space for them

jaunty shell Jul 18, 2018, 11:42 AM

#

send em to meee @wicked oak

wicked oak Jul 18, 2018, 11:42 AM

#

(but in my case they errored, twice)

#

at first, i asked for 1 oculus with touch, from VRMultigames to port it

#

then they sent me 2 (becouse its the "default pack")

#

and they errored

#

and sent me that thing twice

#

now, i applied to oculus start, and even told them i already have a go

#

they still sent me the oculus start pack (oculus rift + oculus go)

#

and then they errored again, and they have sent me another one

jaunty shell Jul 18, 2018, 11:43 AM

#

dafuq

#

and here they are asking for an executable made for the rift/go when I apply to Start

terse moon Jul 18, 2018, 11:44 AM

#

send me one if you like 😅

jaunty shell Jul 18, 2018, 11:44 AM

#

which I honestly cant do since... I'm asking for devkits

#

blobfacepalm

#

also we don't "sell" VR stuff, we sell real estate and buildings by showing em in VR (maybe that's why they wont send us anything

#

but we still do R&D for BIM and AEC CAD

terse moon Jul 18, 2018, 11:47 AM

#

is there a link to the starter pack?

jaunty shell Jul 18, 2018, 11:48 AM

#

@terse moon https://developer.oculus.com/blog/introducing-oculus-start/

Introducing Oculus Start

Today, we're launching a developer program called Oculus Start aimed at providing access, support and savings to qualifying VR developers.

#

you have to create a dev account, fill the form and send your project to them

terse moon Jul 18, 2018, 11:48 AM

#

I'll need to make a project first 😅

jaunty shell Jul 18, 2018, 11:49 AM

#

yup, so you'll have to get your own headset pretty much :p

mighty carbon Jul 18, 2018, 11:49 AM

#

You don't have to have VR project

#

You can show them PIE gameplay

#

Or even pitch a concept (but live project you are already working on is a way better)

terse moon Jul 18, 2018, 11:51 AM

#

Ill need a headset to make what i want to showcase a demo

jaunty shell Jul 18, 2018, 11:51 AM

#

@mighty carbon why did they send me this then ? We have reviewed your application and decided to leave your application open as you need to have a VR build uploaded to your Oculus dashboard before we can proceed.

terse moon Jul 18, 2018, 11:51 AM

#

i could pitch the idea but i think it would come across better as a live demo

jaunty shell Jul 18, 2018, 11:51 AM

#

I've linked a VR video of our projects

mighty carbon Jul 18, 2018, 11:51 AM

#

I didn't have VR project

jaunty shell Jul 18, 2018, 11:51 AM

#

they still want me to upload a VR build out of it

mighty carbon Jul 18, 2018, 11:52 AM

#

Also, I am a solo indie dev. They maybe figured your company can afford to buy Rift? 😉

jaunty shell Jul 18, 2018, 11:52 AM

#

well.. 😬

#

yeah maybe

#

but I'm also the only VR dev in a company of 1800 employees

#

only VR/realtime person even

#

even if we have budgets for hardware, its not like we can buy every device ever released

#

I'd rather be indie tbh

terse moon Jul 18, 2018, 11:58 AM

The information been great, the start up one sounds very interesting

Hand mesh is attached to the closest socket

#

This just makes the player stand still, moving hands doesnt affect character

#

got it working finally 😄

tired tree Jul 18, 2018, 12:16 PM

#

@digital musk the character is spawned in the player controller, depending on if you are running VR or not or are in a 2D preview PIE or not

#

so that 2D testing can be done

digital musk Jul 18, 2018, 12:49 PM

#

@tired tree Thanks, I've been able to get going enough to get by. Does your expansion have a good method for doing a laser pointer mechanic...the debug line from widgetinteractioncomponent is quite terrible, making a big blob where it hits

tired tree Jul 18, 2018, 12:57 PM

it uses a spline mesh for a wobble laser

#

or a stretched mesh for a straight one

Good job on the trailer

mighty carbon Jul 18, 2018, 4:12 PM

#

finally 4.20 has been released

tired tree Jul 18, 2018, 4:12 PM

#

ug

#

that means a few things didn't make it in

#

well, hopes on 4.20.1 then

mighty carbon Jul 18, 2018, 4:13 PM

#

😦

tired tree Jul 18, 2018, 4:13 PM

#

the largest things got fixed at least

#

oh, they mention the mixed reality capture plugin

#

it was too alpha before this

mighty carbon Jul 18, 2018, 4:19 PM

#

GC performance improved x13 (supposedly)

tired tree Jul 18, 2018, 4:21 PM

#

"some operations"

#

regardless anything is good there

#

and I would imagine they had massive issues with the fortnite spam building

granite jacinth Jul 18, 2018, 4:28 PM

#

hm

#

4.20 came out hmm

mighty carbon Jul 18, 2018, 4:29 PM

#

not much VR related stuff

tired tree Jul 18, 2018, 4:35 PM

#

??

#

mixed reality alone is good, they added a ton of fixes, they added magic leap support, and now DedicatedServer toggle works in VR PIE....

#

might want to read down through the VR section at the bottom....

#

not to mention that the general performance improvements are good for VR too

glossy agate Jul 18, 2018, 4:38 PM

#

Yesss. Dedicated server toggle in PIE is gonna be really helpful

mighty carbon Jul 18, 2018, 4:43 PM

#

I mean, nothing for mobile VR in particular and nothing for forward rendering.. I don't see anything about that in the notes

tired tree Jul 18, 2018, 4:45 PM

#

yet they had a ton of mobile improvements across the board

mighty carbon Jul 18, 2018, 4:47 PM

#

right, but is it relevant to mobile VR ?

tired tree Jul 18, 2018, 4:47 PM

#

yes?

mighty carbon Jul 18, 2018, 4:47 PM

#

I am sure most of those are for ES3.1

tired tree Jul 18, 2018, 4:47 PM

#

it is performance improvements

#

and debugging

#

and LOD

#

but no, they probably didn't get to your 1% of the engine that you were looking for

mighty carbon Jul 18, 2018, 4:50 PM

#

right, but too many times all the improvements failed to render in VR using multiview.. So it might be fine in single view (non-VR) rendering using ES3.1, but fails miserably (crashes) in ES2 in VR using multiview.

tired tree Jul 18, 2018, 4:51 PM

#

not talking about rendering changes

#

I am curious about the proxy lod in ES2

#

it "should " work

#

i'll pm you a list you likely missed, its pretty large

mighty carbon Jul 18, 2018, 4:57 PM

#

yeah... I am guessing that anything that isn't related to rendering should work

#

probably would free up some of the CPU resources

sturdy coral Jul 18, 2018, 5:17 PM

@mighty carbon oculus start agreement says you have to have a VR app published on a store, you had your gearvr app

need to see if there is a way we can tweak this to be lower than 2ms for VR:

Garbage Collection Improvements
The "BeginDestroy" phase (unhashing Objects) now runs across multiple frames, using no more than 2 ms per frame. The cost of unhashing Objects will no longer be included in the same frame as the "Mark" phase and reachability analysis.

sturdy coral Jul 18, 2018, 6:19 PM

Hey guys, which axis map should i use for thumbstick locomotion using the touch controllers?

#

Converting to instances meshes on the fly will be sweet. Currently I have just been using the foliage tool to place single objects and move them around

sturdy coral Jul 18, 2018, 6:21 PM

#

New: Added support for clipping ProxyLOD geometry. Clipping volumes will now be supported by the HLOD generation system allowing the user to specify regions to be clipped from the proxy geometry.

#

before they had the ability to clip against landscape

#

no you can clip against any volume which is nice

#

if you have meshes extending through the floor it can make them use less polys/less screen space in z prepasses

mighty carbon Jul 18, 2018, 6:25 PM

#

@sturdy coral how do you clip meshes with landscape or other meshes ?

sturdy coral Jul 18, 2018, 6:27 PM

#

@mighty carbon the mesh combiner and hlod proxy generation have support for it

#

sounds like from the change clipping volumes might have already existed but just weren't supported for hlod

mighty carbon Jul 18, 2018, 6:28 PM

#

by "mesh combiner" do you mean thins https://docs.unrealengine.com/en-us/Engine/Actors/Merging ?

sturdy coral Jul 18, 2018, 6:34 PM

@mighty carbon yeah, at bottom of first screenshot you can see landscape culling section

it will clip any triangles below the landscape

New: Included a sample replication graph for ShooterGame.

(on the same pawn)

placid rampart Jul 18, 2018, 7:05 PM

just figured it out. The touch controllers only work when the HMD is active

#

I was testing stuff without putting it in my head.

sturdy coral Jul 18, 2018, 7:08 PM

no skeletal

they need to hit .15 for that

how did he achieve that?

sturdy coral Jul 18, 2018, 7:26 PM

#

@eager pine the newer api gives you a list of skeleton bone transforms

#

and I think skinned render models

#

New: Improved SteamVR compositor timing and overall engine performance through more accurate CPU utilization data.

#

Code scheduling functions? New: Made Oculus code-scheduling functions available for use by other XR Plugins through the "Head Mounted Display" module.

tired tree Jul 18, 2018, 8:16 PM

the controller one is an estimation on buttons being pressed

#

you can do that without their API

but the point is that you can use the same API for knuckles and the like, and treat them the same

Translucency Support for Instanced Stereo Rendering - This is confirmed not to reduce cpu cost at all in our vr project 😦

how much translucency do you even have?

enough that it should make an impact

tired tree Jul 19, 2018, 4:29 PM

it would have to be a ton

sturdy coral Jul 19, 2018, 4:32 PM

translucency usually isn't writing velocity or shadows so may have 1/3rd less draw calls to begin with

#

(static objects shouldn't be writing to velocity either though)

eager pine Jul 19, 2018, 4:33 PM

#

no changes in drawcalls either

mighty carbon Jul 19, 2018, 4:34 PM

I assume it should be noticeable in scenes with a lot of foliage

eager pine Jul 19, 2018, 4:38 PM

its a open forest with grass, trees, so it should be, we were at 4500 draw calls before activation of stereo rendering, we were at the exact same after activation, and same cpu and gpu cost

you use translucency for your leaves?

you don't mask them?

@eager pine ^ surely you use masked for that, not translucent

unless you are on forward maybe.. translucent for that stuff would look bad with TAA

4.20 and 4.19 have severely damage the performance in VR on my end. When things were running about 45-50 frames per second, it now runs around 2 Frames per second and I really can't tell why it's happening when I try to load a new map.

#

Has anyone had problems with VR and using the new pixel density/screen percentage system?

tired tree Jul 19, 2018, 7:53 PM

#

You likely left screen percentage where it was

#

it needs to be 100 always now

eager pine Jul 19, 2018, 8:05 PM

#

well, for my experience, we accualty bumped up our pixel density to 1.5 without notice of any performance impact

#

just a slight 1-2 fps drop, other than that the benefits from it was worth it

tired tree Jul 19, 2018, 8:07 PM

#

i highly doubt that

#

1.5 is extreme

eager pine Jul 19, 2018, 8:08 PM

#

we are at a stabile 45 fps now, it went from 45 to 42 on a increase of 0.5 in pixel density, but this is a higly optimized scene for vr, where everything is taken into consideration and a 1070 gtx as well

tired tree Jul 19, 2018, 8:08 PM

45 fps is not stable....

#

45 fps is below standard and always reprojecting

eager pine Jul 19, 2018, 8:09 PM

#

stable 45 fps, where there are no big drops or anything, consider that we havent optimized the trees yet

we are aiming for atleast 60, we want 90

tired tree Jul 19, 2018, 8:09 PM

with what platform?

eager pine Jul 19, 2018, 8:10 PM

htc vive, its recommandation is 90, minimum we experienced is 60, but once the player climbs it hits about 90-120 or something, really the level designers work

tired tree Jul 19, 2018, 8:11 PM

regardless, I REALLY wouldn't suggest aiming for 60fps unreprojected with vive

#

All i can say is budget, but would really know more about this reprojection

tired tree Jul 19, 2018, 8:14 PM

#

well you can start by not setting 2.25x the perceived resolution as your default

#

at the very least until you hit 90 constant IN VR

#

1.5 density is not a 50% increase

eager pine Jul 19, 2018, 8:14 PM

#

well, we are currently looking at optimizing the scene, but as for now there are something bottlenecking the performance

sturdy coral Jul 19, 2018, 8:45 PM

#

@eager pine you should set your density to around 1.0 because steam vr also applies its own multiplier by benchamarking your GPU by default

#

if your game is more expensive than the average game, set it below 1, less expensive set it above

#

also unreal pixel density is measured on a different scale than steamvr (pixel count increase is quadratic with changes to ue4 pixeldensity, linear with changes to steam vr application resolution setting)

eager pine Jul 19, 2018, 9:04 PM

#

@sturdy coral So how do you compensate for the terrible pixels that happend when you go under 1? Going under it doesnt increase that much for us

#

unless we go to around 0.5 or 0.6 its a double fps suddenly

sturdy coral Jul 19, 2018, 9:34 PM

#

@eager pine that's because you mostly either hit 90 or you get 45

#

that's why you see a sudden doubling

#

turn on async reproject and turn off interleaved and I think you can more smoothly fall between

Does anyone know how to work with image tracking in ARcore in 4.20?

Looked at Google's sample and set up the arcore image database but my device just isn't tracking any of the specified images. It doesn't help that autofocus isn't working - on that note, is there any way to set focus and exposure on android with UE4?

chilly ocean Jul 19, 2018, 11:14 PM

#

@tired tree I tried setting up the pixel density stuff. This only seems to be a problem when transferring to another map...

#

If I run VR individually in a map, it is fine - but when a server tries to move to a new map, this problem occurs

tired tree Jul 19, 2018, 11:33 PM

#

@chilly ocean you don't have any console nodes firing on level load do oyu?

chilly ocean Jul 19, 2018, 11:34 PM

#

No

tired tree Jul 19, 2018, 11:36 PM

#

check the state of your console commands after loading

#

not entering a value will show you what they are

#

make sure they are the same

#

40-50 was low to begin with though

chilly ocean Jul 19, 2018, 11:41 PM

#

The value for PixelDensity is 1 and ScreenPercentage is 100

#

Yea, I know it was low to start off with, that I know is a map problem that I am trying to fix from 4.18, but to drop to 2-20 fps is ridiculous and unplayable

#

Alright this is weird

#

So this chart : https://www.unrealengine.com/en-US/blog/significant-changes-coming-to-vr-resolution-settings-in-4-19 says the original settings in 4.18 and compared them to 4.20

Unreal Engine

it gets triggered by stereo layers too sometimes

chilly ocean Jul 20, 2018, 12:00 AM

I don't get this message when I set the window percentage higher, but that will ultimately mean lower performance, right?

tired tree Jul 20, 2018, 12:02 AM

yes, but doubt you need to set it much higher

#

it needs to be reported, I don't have easy access to a rift to reproduce for them

mmm, something close with scene captures and non VR has been reported

if someone reported it on oculus with a hard reproduction project i'm sure they would move it up into a hotfix instead.

trying to see if it was reimplemented later..

is it a reason for a sad.face ? or nothing special and impactful ?

sturdy coral Jul 20, 2018, 1:33 AM

#

I don't know what it falls back to when there is no grid, seems like it would slow everything down since it is used in forward and deferred; it might have just been an intermediate commit where they brought it back later

btw, if the fix doesn't make it into launcher's version, it will always be in Oculus repo

@spare yew it just worked straight away when I was using the google example project and the google branch of unreal a couple weeks ago, i assume 4.20 uses the same build as that

@sturdy coral if there isno grid, directional lights still work

nice

#

how do you folks handle multiple levels in a single player game ? Is it one persistent level with bunch of sub-levels or bunch of persistent levels (that might include sub levels) ?

#

If latter, how do you handle player beating level and exiting it and then how do you handle loading next persistent level ?

glossy agate Jul 20, 2018, 4:06 PM

#

Mine are multiple levels. When a match ends, I just Travel all the players back to the level and GM select room which is its own level

#

My load times between levels are only 2-3 seconds

fleet plume Jul 20, 2018, 4:28 PM

#

for a second i thought by GM you meant game master

#

though game mode is not bad either 😄

mighty carbon Jul 20, 2018, 4:31 PM

#

@glossy agate so you load default (persistent) level where players dwell until match is selected and then move players to the selected (another persistent) level ?

glossy agate Jul 20, 2018, 4:31 PM

#

Yep

#

Makes it easy to wipe the game mode and game state stats that way too

mighty carbon Jul 20, 2018, 4:33 PM

#

hmm.. it seems to be multiplayer thing

glossy agate Jul 20, 2018, 4:33 PM

#

For single player you would just use the open level node easy peasy

#

If it’s just smaller chunks for each arena like mine is it’s easier and clean

#

And if you needed persistent stats to carry over you could just store them in game instance and they will persist the whole session

mighty carbon Jul 20, 2018, 4:38 PM

#

what happens to the the level player was on before opening a new level ?

glossy agate Jul 20, 2018, 4:56 PM

Hello all, im just an end user without dev skills trying to figure out an issue with Archangel: Hellfire, its based in unreal engine and the multiplayer portion is undersampled and does not respond to steamvr supersampling settings, im using a vive by the way and there are other users reporting the same issue.
The only thing that has made any difference this far has been adding changing r.screenpercentage in the engine.ini.
The odd thing is that it changes the rendering but doesnt the scale the output to fit the HMD so the eyes go out of alignment instead of actually supersampling, if screenpercentage is set below 100 the lower right of the panel in the hmd shifts up towards the upper left, if set higher the lower right goes away from the upper left.
Here is a desktop screengrab from when it was set at 200

Here is the thread if anyone knowledgeable feel like taking a look:

guys, i have a strange issue, not something i can't work around, but it bothers me that i don't know why it acts this way. So the problem is that i have an elevator which i move on tick. This elevator consists of an actor with a childactor (carriage) which i move up/down depending on which floor u select. When it moves, i am always one frame behind. So i tried moving the carriage out into the same actor as the elevator itself (so not using childactor), and then it moves 1:1. So i thought maybe i need to add an actor prerequisite between the childactor and the elevator (parent), but that does not seem to have any effect what-so-ever

tired tree Jul 20, 2018, 8:49 PM

#

it is def a tick order issue jonas

#

but if they tick in entirely different groups

#

it won't work

if that makes sense?

then the character is behind 1 tick?

you worded it like the carriage was behind

#

as i said, i know how to work around it, but it bothers me that i don't understand why it's behind one tick

sturdy coral Jul 20, 2018, 8:51 PM

childactor may be doing some stuff overriding tick dependencies and stuff too

unless you have the tick preres

you could do it on the character itself though

just as a far fetched experiment to figure out if this is another one of those pesky childactor things, i could try move a different actor from the elevator

Just got a response form the devs, the unreal engine version for the problem game i asked about is 4.18

Was the solution to r.screenpercentage to run the preview resolution at the native resolution of the hmd on 4.18 as well?

eternal inlet Jul 20, 2018, 9:38 PM

#

@sturdy coral yes, but what i need is the opposite, an actor to tick before a component

#

as i understand, these two nodes, do the opposite

#

or maybe im missing something super obvious

sturdy coral Jul 20, 2018, 10:01 PM

#

@eternal inlet in your screenshot you are calling AddTickPrerequisiteComponent on the elevator with CMC as prereq; instead call AddTickPrerequisiteActor on CMC with elevator as prereq

glossy agate Jul 21, 2018, 2:23 AM

#

@eternal inlet why not have the carriage as it’s own actor with the shaft as meshes for it. then put in an array of location transforms per local actor. Would work more easily for different heights ect you can setup quick in the levels

eternal inlet Jul 21, 2018, 7:40 AM

#

@sturdy coral but doesnt that take two actors as parameters?

#

I’ll give it a try later today.. just thought i had tried that

#

@glossy agate i have all the shaft meshes added as staticmeshcomps to the elevator atm. They get added from an array of bools (hasdoor). That way i control if i want a door+shaft or only shaft

#

I do have the carriage itself as a seperate actor, but as mentioned, i had troubles forcing the correct tickorder

sturdy coral Jul 21, 2018, 7:47 AM

@eternal inlet it is a method on actor component

Hello. I was wondering what other developers are doing for dynamic shadow casting in AR. I'm currently using modulated shadows (only ones that cast on unlit) and a plane wit a material that projects the video feed onto it. It works but I was wondering if there are other solutions around that don't involve using the video feed.
