virtual-reality

[full junco]

thats the old stuff they talked about there @sturdy coral

the stuff that also existed in 4.15 etc

what do you mean with "manually changing the base resolution"?

[sturdy coral]

yeah I don't know if the oculus adaptive is wired into the TAA stuff but I assumed so when they mentioned it on the stream

I don't know if base resolution is the right term

you basically set your render target resolution with vr.pixeldensity

and then r.screenpercentage tells it how much of that to render to

and it will TAA upsample to the vr.pixeldensity amount

[full junco]

dont get why "upsample"?

[sturdy coral]

they should have called it temporal supersampling or something

[full junco]

well I dislike that new system with vr pixeldensity whatever

I want 100% to be 100% of the available pixels

but doesnt matter much

[sturdy coral]

pixeldensity 1 means the recommended render target size

[full junco]

yeah I dont care at all about what "others" recommend

[sturdy coral]

due to lens warping, to get 1-1 in the center you need more than 100% of screen pixels

and other HMDs might have more or less distortion

so you wouldn't want to worry about what it was relative to screen pixels

if the relation to screen pixels was different per hmd anyway due to how strongly it warped things

[full junco]

but the thing with manually changing the res was that changing the screen percentage causes a buffer resize

and it will be same now I would think?

[sturdy coral]

I don't think so, I think they reworked that underneath

[full junco]

the buffer needs to be at some size

[sturdy coral]

the buffer size will come from pixeldensity

[full junco]

there is still a constant cost associated with having it too big

[sturdy coral]

and r.screenpercentage now will tell what percentage of that buffer to render to

but when the TAA history buffer will now always be vr.pixeldensity

size

[full junco]

so you mean I would set the vr pixeldensity to 1.7 - 2.0 and then just modify the screen percentage?

[sturdy coral]

and your rendering to the smaller one will get sparsely sampled into the TAA history buffer

yeah, set vr pixeldensity to whatever your supported max will be (lower on 4GB cards)

then you should just drive r.screenpercentage

but there might be more details on the "right" way to do it to feed into the new dynamic res system

[full junco]

I dont believe changing the r.screenpercentage has no constant cost any more

r.screenpercentage is still the regular way to change stuff for non-vr games?

so how does that work there?

[sturdy coral]

I think there is a difference between VR and non-vr now

but I can't remember the name of the commands for everything when doing it in non-vr

[full junco]

are you fully sure the TAA upsample stuff is used in VR?

[sturdy coral]

yeah

[full junco]

almost no one even uses TAA in VR

[sturdy coral]

I haven't looked at it on a demanding scene, with foliage etc.

I think their shader doesn't really support going lower than 50% in each dimension

[full junco]

50% of what?

[sturdy coral]

for vr, r.screenresolution

[full junco]

well that would be bad. at the moment my max is 200% SP and it can go down to 70%. so min is less than 50% of max

[sturdy coral]

you can still do it, I just don't think the shader will search far enough and you might see some artifacts

mainly on scrolling textures and stuff

[full junco]

can you disable that TAA upsample stuff and do regular upsampling?

[sturdy coral]

the old shader only searched a cross pattern of neighboring pixels, the new one expands it to all 8 neighbors and I think if you go much below 50% that won't be enough

you could probably use some of your old code to resize the viewport when going below 50%; just basically allowing you to change vr.pixeldensity without hitching

but without getting the benefits of the new stuff when you are in that regime

[full junco]

how much better does the TAA upsample actually look like?

[sturdy coral]

If nothing is moving you basically can change it without noticing the change

on a real scene though I don't know. probably for things with lots of specular aliasing and stuff you will notice them sparkling more

for scrolling textures you will notice more ghosting when something moves in front of them across them

[full junco]

well you know my game

no specular stuff there

also no moving textures

[sturdy coral]

yeah your biggest issue may be foliage

because the velocity buffer is going to be doing the reprojection of the history stuff

and it is going to be very low resolution in some situations

I think velocity already runs at 50% resolution normally , I don't know if they are doing anything special for taa upsample, like always running velocity at a higher res

[full junco]

they probably have a reason why they dont want to make dynamic res support VR yet

something has to look bad if you change the screen percentage too often

[tired tree]

they specified that different platforms require different thresholds

for when to scale, how much, ect

and they didn't want to release on untested platforms

[sturdy coral]

for things like specular aliasing, you are going to be undersampling it by more so they will sparkle more

[tired tree]

that was after being specifically asked about VR for it

[sturdy coral]

with normal TAA if a pixel's neighbood changes too much beyond what it predicted from history and velocity, it just forces a stronger weighted update of that pixel

with the new way

it will have to force an update of the pixel and its neighbors

it might make for a blocky update around moving things on the silhouette where the velocity stuff is running at too low of a resolution and is mispredicting

but I think they do some kind of a gaussian thing, so it might just be blurrier

but that could make like all foliage look blurrier, etc. really thin things like grass that are now too undersampled in the velocity buffer

without wind or vertex animation it should be better

@full junco when you reach 50% it also isn't going to perform as well as really running at 50%, because it is going to still be sampling textures at the same mip level as if it were 100%

so it will use more texture bandwidth

[full junco]

hm

[mighty carbon]

how is your game doing @full junco ?

[full junco]

@mighty carbon quite well I think

[mighty carbon]

can retire early ?

😃

[full junco]

not yet 😄

but thats fine

I dont expect a crazy amount of people to buy it in the current state

I just want to have an active community that helps me develop the game further

and that I have

so I'm happy 😄

[mighty carbon]

cool stuff

[glossy agate]

Yeah you got quite a few people in there. Really cool

[real needle]

hey guys

is anyone around here, who went through all that pain in the **s what is packaging a game with the leap motion plugin in UE 4.15 ?

packaging finishes successfully, but the executable crashes somewhere utilitzing the async loader..

[hard bear]

@tired tree Hey Morden, working just to setup a blank 4.18 project with the VR plugin and pretty much all is working except for one thing so far which is trigger/grip on objects. I've migrated over the gun, car, etc objects from the example project over and doesn't seem to jive. The example and my project are both 4.18 so I wouldnt' think too much would be different for it not to work, probably something simple but I was looking at the wiki/thread and didn't see anything yet on why.

[tired tree]

@hard bear the template uses a custom trace channel and a gameplay tag table, both need to be transferred if you want it working the same. PM me if you have more questions though to not flood here.

[hard bear]

Ah will do! thank you!

[quartz bay]

Is there a way to get the launcher to recognize a source build version of the engine?

[full junco]

no

you dont need it in the launcher

[candid viper]

The changes with r.ScreenPercentage and vr.PixelDensity make TAAU when used with VR more confusing than it might have been. I'd have preferred vr.PixelDensity of 1 meaning equal to render resolution, then have an api to query the recommended vr.PixelDensity for the hardware. Anyway, potentially the interesting use case for VR is for lower end gpus. Originally, you'd lower the screen percentage so the size of the framebuffer presented to the graphics driver was lower, saving rendering cost. With TAAU, you keep the size of the frambeuffer being presented the same, but you lower r.ScreenPercentage. So the GPU renders the scene at a lower resolution, then the TAAU upsamples that lower resolution render to the higher resolution framebuffer.The TAAU shader cost goes up a bit - say something like 25-50% higher than the original TAA cost. Provided that extra cost is lower than what you gained back by lowering the resolution rendered at, you win back some gpu time, or rather get higher quality for the same gpu cost. There are some useful pictures on this older Intel article on it. https://software.intel.com/en-us/articles/dynamic-resolution-rendering-article Look at figure 5 - that shows how TAAU (a much more basic version than UE4 has) results for upsampling for a render 71% of the final framebuffer size. Now dynamically changing the render resolution, like the Oculus Adapative Pixel denisty (and the version @full junco did for SteamVR) adds some complications - depend on change rate etc, it interacts with the TAAU. That may or may not cause issues - I think for now Epic are being cautious with that side of things.

[jaunty shell]

Hey lads, throwing a guess here, do you think two Titan V would work for VRSli, even if the cards use the -similar but not the same as sli- nvlink ?

We're looking to get a V to considerably boost our workstation and get the smoothest experience possible for our engineering building models without having to optimize the F out of them

[pearl tangle]

The titan V doesn't work in SLI at all does it?

[jaunty shell]

yeah that's the problem, its using another standard called nvlink

uh

nvlink

[pearl tangle]

yeah but the titan doesn't support that

only works on quadro

[jaunty shell]

fuck

oh well

[pearl tangle]

https://www.techpowerup.com/239519/nvidia-titan-v-lacks-sli-or-nvlink-support

hah first article on google

[jaunty shell]

yeah I mixed up techs 😂

[pearl tangle]

just SLI 1080 TI's on there if you want to go for SLI

[jaunty shell]

I have a few problems with going for a sli actually

[pearl tangle]

yeah sli is a bitch, not worth the effort

always causes more headaches than it solves

[jaunty shell]

75% of our software has been made to work with single GPUs

the only one that CAN use sli would be UE4, and it requires building stuff on the VRWorks branch

but I cant use it, because I'm tied to Datasmith, which will only work on launcher UE4 😦

[pearl tangle]

did you do the survey they sent around this morning?

[jaunty shell]

not yet

[pearl tangle]

didn't realise they were going to go that route, should be interesting though if they are changing around the enterprise license model to focus on that. Since I am an enterprise partner at the moment and we pay a shitload more than what they are indicating that would be at

[jaunty shell]

We uuh

are not declaring anything 😂

we're not really selling anything with UE4, so I guess we're in the free licencing model

but yeah, I had a quick look at the survey yesterday and am surprised at how expensive some tools can be

@pearl tangle I got the greenlight from the boss to get a V earlier this morning, but I'm still not sure about the real gains it will get us compared to a single Xp

[pearl tangle]

you can stay in that. I get the enterprise agreement so i have dedicated support etc

[jaunty shell]

I mean the benchmarks are showing a nice performance bump

Oh dedicated support is sweet indeed

[pearl tangle]

oh yeah it's a big boost for sure. But over the 1080ti that already has 11gb ram compared to the 16gb in that, the price difference is not really worthwhile. You doing arch viz or something i assume?

we get access into the UDN as well so ticketed support system and better access to stuff

[jaunty shell]

Even heavier, I'm doing building engineering

[pearl tangle]

on which side of things?

using VR in unreal to understand space better or just to illustrate concepts or pulling in more electrical and fire and whatnot?

[jaunty shell]

BIM related stuff

first one

our company is doing the conception and construction of massive buildings

https://i.imgur.com/62nlhlj.png

this is an example I imported a few days ago

every part must retain its shape, we can't merge stuff

that's why I need brute power

[pearl tangle]

nice. You tried any of the open street view integration? I was just playing on twinmotion's integration with it today

[jaunty shell]

yeah we're using it with TM aswell

I tried to get the OSM plugin for UE4, but my C++ skill is not enough to improve the one available on git

[pearl tangle]

need to just take that part out of there and integrate it as a proper plugin with that exact functionality into unreal and i would be happy. The adding characters and bikes and cars in is nice, but not quite high enough quality. interesting software though

[jaunty shell]

for sure

we use it in production mode for commercial videos

[pearl tangle]

the OSM plugin 1 works fine. My only annoyance with them all so far is i can't get the elevation from them, need to try merge that in later. The datasmith integration with cityengine is relatively decent

[jaunty shell]

https://i.imgur.com/rdSeAK5.jpg

something I've put up recently

[pearl tangle]

i feel like thats sitting on the twinmotion site somewhere

[jaunty shell]

haha nah :p

I guess I could send it to them for demonstration purposes

the workflow for this kind of visual stuff is a bit different, since we can merge assets by material

this is currently 50% of what I do for work, but we want to bump up the BIM related part (that's where Datasmith and the Titan V are important)

our models are so complex that performance is very low even on pancake realtime

[pearl tangle]

the python scripting stuff will be coming into datasmith by 4.20 i think

that should let you optimize the import pipeline more to tweak things a bit like disabling shadow casting on different things and whatever you need automatically and run other things straight in the engine

[jaunty shell]

the first iteration is already in since 4.19/DS 0.18 I think, just not documented at all

[pearl tangle]

yeah its available to switch on i think but not really done anything with the pipeline

[jaunty shell]

yeah it sure is going to be a great addition. But then we'll need a python coder 😂

[pearl tangle]

a lot of 3D places already have them doing all the other stuff so should be able to start to merge in those kind of functionality to unreal, or at least hopefully those guys start to release their stuff

[jaunty shell]

yeah hope so

https://i.imgur.com/USCYzIx.png

another one I found

using a bit of DF stuff here

performance is rather nice compared to cascaded shadows

shame its not completely VR compatible

[pearl tangle]

I wrote a blueprint before that would let you convert things over to instances and back on the fly that gave massive performance increases. I think somebody actually released 1 similar on the marketplace too, that might help you out performance wise for VR viewing

[jaunty shell]

yup, the HISM tool, I've bought it

its awesome...

... when the models are setup to use instances...

... which is not the case here 😂

[pearl tangle]

yeah I created a tool which doesn't require them to be the same 1, so that you can have them at different scales and materials etc and it will still handle it. You just "group" the objects to what you want to put into the instance

haven't used it in a couple of years though but that was the same thing I was up against, but there were enough things that were similar or based off the same model they just needed slight variations between them. The datasmith python integration should let you do that grouping and conversion on the import I would think

[jaunty shell]

indeed, a python script to optimize your scene would be awesome

maybe an automated ISM/HISM, LOD and HLOD pass in a click

heck, even a script that would piggyback on datasmith and do the optimization when importing your datasmith asset would be awesome

I really want to see what they have for us regarding material swapping too

[pearl tangle]

yeah thats definitely in there with the python integration part of it, the epic guys were showing me a demo 3-4 months back when they were over here

both of those

[jaunty shell]

shieeee

I've been trying to get a workflow like this for a full year

😐

[wicked oak]

@jaunty shell doesnt work like that

ive used plugins to blanket turn everything into instanced meshes, performance tanked

you need to do it manually on the correct parts

[jaunty shell]

that would require way too much time/work :/

we are looking for a way to get as close as the "one click" solutions you can get in softwares like Enscape or Twinmotion (to some extent)

but these softwares are merging assets by materials, thus won't allow us to get all the meta data we want when exploring the model in VR

[mighty carbon]

https://www.vrfocus.com/2018/02/starbreeze-confirms-starvr-ipo-talks-with-acer/

consumer edition of StarVR ?

[granite jacinth]

Doesn't matter at this point inho

Vive and Rift have already dominated the PC market

VR home brand names at this point

If anyone is going to get a new HMD they will wait for their brand to release a newer version

Pimax will be in 3rd if they can ever get their issues sorted out

But let's not forget about that elusive WMR HMDs that come in all shapes and sizes

And colors

[mighty carbon]

but the FOV !

[nimble edge]

Does anyone know how to modify the stock VR template so a new "pickup cube" is spawned in your hand when the trigger is pulled? When I spawn it, it ends up on the floor at my feet.

[sonic lake]

@nimble edge it drops to the floor because you are not grabbing it, so it is not attached to the motion controller

[nimble edge]

@sonic lake It appears on the floor. I was expecting it to show up and then drop, and I'd figure out attaching it later.

[sonic lake]

Ok then it is very likely a collision related issue

[nimble edge]

Ok, thanks. I'll look in to it tonight when I get a chance. This is all new to me.

[tired tree]

@nimble edge you are probably getting the actor/vrrrootcomp transform to spawn it at, get the motion controller transform instead

[mighty carbon]

interesting... no commits to the repo for 4.19 today, at all

I wonder if entire Epic participates in the jam

[tired tree]

snow storm

[mighty carbon]

o.O

damn weird weather

[granite jacinth]

wtf

Manus gloves 4x the original price

Either that, or I don't remember the original price right

But swear it was $250

[nimble edge]

The Dev Kit was $250

Looks like it went up...

[granite jacinth]

hhmm

Anyone have any issues with their VR game always being in Fullscreen mode in 4.18?

Using this node in Editor works...not in Packaged though

Alt-Enter does nothing

[glossy agate]

Did you try setting it in settings instead? under the "play" tab or something like that?

[granite jacinth]

Yeah, going to see about hardcoding it in config now though

[granite jacinth]

hmm damn

even the hardcode that didn't allow me to switch in editror

still causes the damn thing to go fullscreen in packaged. boooo

[real needle]

@granite jacinth I think its hardcoded to be fullscreen

[granite jacinth]

Pretty sure I never had this issue before 4.18

oh wtf

since when

It cause peopel with 4k screens...

[glossy agate]

Oh I thought you were trying to get it to be fullscreen haha

[granite jacinth]

to well... go 4k res

I don't want it to be fullscreen

I want the player to have the choice

[real needle]

I've never had the start in fullscreen etc do anything for me since "start in VR" became an option

[granite jacinth]

But umm, oh wells, if it can't be done.

hm

[glossy agate]

Cant you set it to a smaller resolution though?

[real needle]

You can set res of preview window but I think it acts as "fullscreen" even though it's a windowed window

[glossy agate]

If its a perf issue

[sturdy coral]

The oculus branch used to have some customizations around setting mirror fullscreen separately

[rocky nimbus]

Is there an easy way to pause game when the HMD is taken off? It's mandatory for the Oculus Store now but I can't seem to find a simple solution (it should be)

[sturdy coral]

@rocky nimbus you can register a callback for the worn state

[rocky nimbus]

@sturdy coral Any references you can send my way? So far I've not found anything native to UE4

I'll see if anything like that exists when I hop back on in an hour or so

[sturdy coral]

Search the HMD module or plugins for "worn", I don't remember if it is exposed to blueprint. You can query the worn state as well as register a callback/delegate

[tired tree]

its exposed

[rocky nimbus]

@tired tree @sturdy coral Nothing by default, in-BP or in the plugins

[sturdy coral]

Look in the plugin code not the plugin list

It isn't a plugin called worn nor is it in the description of the HMD plugins

[rocky nimbus]

What do you mean 'plugin code'?

[sturdy coral]

The source folder for the Oculus plugin if you are targeting the Oculus store. It should also be in the common HMD interface though

[rocky nimbus]

oh wait,

I'm seeing the delegates

[sturdy coral]

https://docs.unrealengine.com/latest/INT/API/Runtime/HeadMountedDisplay/IHeadMountedDisplay/

WornState

[rocky nimbus]

That's not in BPs by default, it seems. Also, would I need to run this in a loop?

Shouldn't the delegates I screenshotted work if I set them up to custom events?

[sturdy coral]

It shows it in blueprints

https://docs.unrealengine.com/latest/INT/BlueprintAPI/Input/HeadMountedDisplay/GetHMDWornState/index.html

Shows a blueprint node

[rocky nimbus]

Strange...

I'm not seeing it

[sturdy coral]

'Put on head' etc may be a synonym for the worn delegate through some blueprint renaming thing

It also may have changed version to version to different names

[rocky nimbus]

I'm using 4.16 as well, it may have been re-named

Yeah

'Connected' likely doesn't mean Worn though

[sturdy coral]

Probably not

You may get no initial event when the game starts if it starts with HMD on

That may just be a SteamVR plugin bug, I can't remember

[rocky nimbus]

Should this not work?

Fail

[idle plinth]

Hey Vr people. So im having a problem with editing in Vr mode in unreal engine. The text on the UI is very blurry until im about one feet away from the text or closer. which makes it almost unreadable

anybody know why this is?

[tired tree]

worn wasn't fully exposed / fixed back in 4.16 I don't beleive, think they "fixed" it in 4.17 @sturdy coral @rocky nimbus

that event either

wasn't being thrown when it should have been

exact fix commit date is hazy though

[proper osprey]

Hello. I have a question. I have a high end computer (gtx 1080 ti, i7 6700k). How can I make sure my project will run on lower spec computers? Is there a way to simulate various computer specs?

[mighty carbon]

so, I hooked up AnyKey node and saw that nothing that Epic's docs have matches actual buttons on Gear VR motion controller.. 😦

[glossy agate]

Thought you were done with mobile? Or are you building something for Go when its released?

[mighty carbon]

well, if I don't get Go, I'll buy it for sure

so I'd rather have working template now than later

plus I designing a house and I think mobile VR is less cumbersome when you want to show it to various people

[glossy agate]

Good idea

[mighty carbon]

also, as much as I love 6DoF, it's a magnitude more work on design and implementation side when it comes to gameplay

than for 3DoF

I hope that Go will sell enough units

[wicked oak]

@mighty carbon the dinosaur game i worked on got 4k dollars in sales

im working on adding controller support

not having it day 1 was a HUGE mistake

absolutely huge mistake

turns out 70% players use controller, so the game lost a lot of good reviews due to the controls being headlock only

[mighty carbon]

controller as motion controller or gamepad ?

[wicked oak]

the motion controller

that shit 3DOF one

[mighty carbon]

oh wow

[wicked oak]

but i just built a prototype

and damn, it is a huge improvement

much better than headlook for the aiming XD

even if its still not completely accurate becouse 3dof

but it kind of becomes a "mouse pointer"

[mighty carbon]

aye

didn't know that many people got controller

[wicked oak]

pretty much every one

[granite jacinth]

New gear gets it included ?

[wicked oak]

yes

[granite jacinth]

Well that's why

Just saw Olympics ad for it

Heh, Samsung is funny

They showcased Gear VR not Odyssey in the ad

Intel also did a VR ad

Guess they have some VR cameras placed all over so you can Live view

[wicked oak]

im just interested on the full olympics

i really enjoy martial arts

[granite jacinth]

Haven't looked at it yet

[wicked oak]

1v1 PvP at the highest level

taekwondo and judo tend to be great

[granite jacinth]

Heh

[wicked oak]

pro level taekwondo is serious movie stuff lol

with the flying kicks

[glossy agate]

My buddy texted me yesterday wanting to buy VR after seeing the add. Asking which one to buy for watching the olympics. Think its only mobile VR though

[granite jacinth]

I don't usually watch too much of the sports. Opening ceremony

Usually

[wicked oak]

i only really care about the martial arts

its winter olympics

no martial arts

so i give 0 fucks

[granite jacinth]

But some of the events this time around are pretty competitive

When will VR eSport be Olympics event?

[wicked oak]

lol

its e-sports, even if vr

wich means zero chance

[granite jacinth]

You never know

[wicked oak]

the main reason is that no e-sport can really "be" in the olympic comitee

at least right now

[granite jacinth]

Times are changing

[wicked oak]

in sports, the rules are public

in games, the rules are controlled tightly by a central organism (game dev)

this is a huge difference

[granite jacinth]

I men. Imagine a VR Battle Royale Olympics event. Definitely could happen.

[wicked oak]

becouse olympics are every 4 years, in 4 years how many games can become popular and stop being popular?

what game do you choose for the olympics

[granite jacinth]

Every country competing

[wicked oak]

Lol, or Dota

(for moba)

or do you play Overwatch, or Counter Strike (for shooter)

[granite jacinth]

Hmm yeah. Team sport

[wicked oak]

it would be so politized it would 100% be on the game dev that pays mre

(so LoL and overwatch)

and it wouldnt have good reputation

keep the olympics for olympic sports, we already get really cool game tournaments

[glossy agate]

haha have Dr Disrespect running the olympic torch up

[silk lodge]

hey!! I have to buy a bunch of games that cost $5.00 (not 4.99) - preferably something I could get a written agreement that I can play at free public VR demos- because I just made 8 new accounts that need activating

do any of you have suggestions for games that are friendly, fun, and easy on first time users?

[real needle]

@silk lodge Not where you'd be able to get a commercial license for sure..

[silk lodge]

I work with developers to secure licences

but this time around, I've gotta buy a bunch. I can't be given keys

[mighty carbon]

@silk lodge "I work with developers to secure licences" <- what do you mean ?

[silk lodge]

I mean that I don't just buy games and play them. I make sure it's cool with devs to play them!

[mighty carbon]

oh, I thought you secure licenses for developers.. Like 3-rd party IP licenses

[silk lodge]

I run a VR group - http://austinvirtualleague.com/ - and we play pvp vr irl

[mighty carbon]

Austin.... I miss living in Austin 😦

[silk lodge]

it's nice! 😃

[mighty carbon]

that why I miss living there 😉

[mighty carbon]

https://www.youtube.com/watch?v=mQ0mPrNdZbA

Blender 2.8, all real-time

I wonder why UE4 can't render like that

[silk lodge]

it can

[mighty carbon]

eeh, I don't think it can without baking lighting

also, UE4 has no real-time GI

[tired tree]

eevee is "realtime"

its still re-rendering on viewport shifting

its not game engine realtime

also I don't see that it supports "realtime" GI, it has the irradiance volumes

its still taking longer than a normal frame to render the view

wonder why the aliasing is so trashy in that video though....

[cosmic shoal]

Eevee is progressing better than I tought

and yeah it does have some artifacts still that are very distracting, aliasing could be eliminated if you just render at twice resolution and scale it down (dunno if eevee suports that tho)

[tired tree]

its amazing for blender for sure

should really improve workflows to ue4

[mighty carbon]

any idea why TraceByChannel works differently than TraceByObject in 4.19 ?

when I trace by channel, the hit point sticks to the surface, as expected. When I trace by object, there is some kind of padding and hit point is always above the surface :/

on top of that non-line traces by object get stuck inside player's character :/

[tired tree]

sounds like one you are using(tracing) complex collision and the other you aren't

[mighty carbon]

nope, all settings are identical :/

i'll just stick with tracing by channel then

[craggy obsidian]

Or ask in the forums as it could be a bug?

[wicked oak]

@motorsep#8292 unreal cant becouse unreal needs to run fast

blender eevee is all sorts of spectacular overkill

becouse even if you have 3 fps is completely fine

and honestly if you bake lights properly you can do a lot better than that blender scene

that blender scene is such a massive overkill for reflections

it literally just renders the whole scene a ton of times, per reflection

thats why when he is editing it you ssee stuff popping

thats from the scene captures getting rendered

i also think that scene does use baked light a bit

[cosmic shoal]

For Unreal arch-viz it's the same way, I use reflection planes everywhere and generally don't care about performance, turn everything to 11, use huge lightmaps etc. I have to turn settings to low when editing the scene just to not go crazy.

[wicked oak]

@main gustn#6226 exactly

unreal actually has a good deal more features than blender eevee at the moment

[cosmic shoal]

Yeah, but for people who use Blender it's a huge thing to keep everything under one app. It's convenient enough that it's got me exploring the switch myself.

[wicked oak]

thats the idea

eevee + gltf can allow you to author your scene in blender, and export it as a whole to unreal, keeping materials and textures

with the materials getting translated automatically

also, blender eevee would allow movie stuff better

after all, blender is a MOVIE software

[dusky moon]

I absolutely love eevee but I don't know why I still prefer to create materials inside UE . it just feels more safe to me even if that gltf thing is smooth already 😄

[wicked oak]

@dusky moon the idea is that you could preview the mats in blender when sculpting/modelling

and just export the model all ready

substance also supports gltf

so you can export mesh + material setup in 1 file from substance, and not having to setup the mat inside unreal

[cosmic shoal]

I have oly dabbed with Blender so it's all pretty alien to me, and yeah I'm pretty confortable making materials in Unreal also.

[wicked oak]

they are working on having the materials integrated

they arent still fully integrated cross render engines

so the same PBR material you make for eevee will work the same way in Cycles pathtracer, and if you export it, it will also work in unreal/unity

[dusky moon]

@wicked oak that is certainly awesome! I'm hoping that it's flexible enough workflow for iterations as well.

[cosmic shoal]

substance.. man all the stuff we have to learn (and buy) just to play with the big boys..

[wicked oak]

substance is a godsend

so much better than the older way of using photoshop

[cosmic shoal]

I've seen the unreal to substance tutorials, so cool.

[wicked oak]

absolutely massive improvement

[dusky moon]

I just switched to substance from Quixel and my life is better now

Anyways, I'm really stuck with fixing Aliasing on MSAA for a texture I made in Substance ... It's a 'Tile concrete wall" and I get massive aliasing on tile edges using MSAA ... any tips ? I lowered the intensity of Normals but it still sucks

Also used this "Normal to Roughness" thingie which doesnt seem to help much

pretty obvious here :

▶ Play video

^^ so Steam doesn't give a damn about what they are letting on

@dusky moon you can't AA on textures with MSAA as MSAA works with actual geometry only

[sturdy coral]

@dusky moon there are two different normal to roughness things I think; one bakes into roughness texture and one is based on screenspace normals

For roborecall I think they said they used both

[dusky moon]

@sturdy coral yes, one should be applied inside roughness texture (compositing) and the other is inside the material "Normal curvature to roughness". I used both and didn't help

@mighty carbon well does that mean I should forget normal maps as long as I use MSAA ?! didn't know it's that rough

[mighty carbon]

either that, or accept the fact and move on

or use another AA method

[dusky moon]

yeah, well as I'm relying on text msaa+forward is a must so I'll compromise normals I guess. thanks

[wicked oak]

getting sent more free hardware from oculus, sweet

[real needle]

@dusky moon What is your supersampling %? I was able to get rid of the aliasing using the texture technique. But I'm running at 150% which is probably helping

[dusky moon]

@real needle I'm at 200 % actually. maybe I should test lower ones though. thanks for reminding

speaking of free hardware, is Vive still generous to hand out dev kits for the pro one ?!
@wicked oak Do you know if Oculus ships standalone one yet to devs !?

[wicked oak]

@dusky moon hahahahah

you wont get shit from vive/valve

valve has NEVER been generous

i asked them for a second Vive after actually getting 40k installs on VRMultigames

and they took the time to answer the email with "go buy one"

[dusky moon]

oh well, I used to get 1 from Valve last year actually 😄

maybe HTC

I'm actually looking forward to see unreal dev grants like 2 years ago which were dedicated to VR equipments only

good ol times haha

[wicked oak]

oculus is sending me an oculus Go

4 weeks till it arrives tho, its going to almost be release XD

i wonder if i should try to prepare something for Go

but, what?

[dusky moon]

oh thats nice!

well one thing that needs to be cleared is its platform

is it gonna be oculus store

or gear vr store ?

[wicked oak]

ive seen gearvr doesnt really bring much profit

the dinosaur game i got hired to port has got 3k dollars

and it launched in "Games", and frontpaged for a good while

looks like gear people really like their movies and "experiences" more than games

[dusky moon]

Yeah absolutely, in gear 360 stuff can sell real well. but anyways this oculus go thing .. I hope it's not another whole separate branch in terms of dev/shipping because the market is already chunked badly

[wicked oak]

not really, its going to work with the gearvr store

it runs gearvr apps

[dusky moon]

Fine, anyways seems like the new feature in 4.19 "Proxy LOD" is super handy for making optimized distant objects. so I guess we won't need to merge actors into one mesh by hand anymore.

[wicked oak]

you could do that before

with instalod

it doesnt work as well as you would think. Material/texture quality tanks SUPER hard

and lightmaps go to shit, so they can artifact a bit

[main ether]

@jaunty shell that looks like the Apple spaceship a bit 😃

[jaunty shell]

@main ether it does look massive in VR, even more when you look at the real WIP building 😃

[main ether]

i bet!

i love archviz stuff 😃

[jaunty shell]

yeah its pretty interesting

some things can be really challenging though

[main ether]

has anyone done something with climbing in unreal? (in c++ preferably)

[tawdry dragon]

Hey guys, might be missing something really simple here. I have a BP actor with a widget that I want to always try and be infront of wherever you're looking. Im trying to use "Get forward vector" on the VR Camera's rotation, but it doesnt really make the Actor follow my gaze

Anyone got a hint to what I can do? 😃

nwm me... Im stupid.. Forgot to add the location to my multiplication

[pearl tangle]

@tawdry dragon Why not just attach it to the camera?

[tawdry dragon]

mostly because I dont want it to follow the camera at all times

only when it gets out of view

its a ingame menu, so moving around all the time when people look at the different parts is not ideal

So i have a VInterp function running when it gets out of view, nice and steady 😃

[jaunty shell]

hey everyone, I'm trying to troubleshoot a reccuring problem I have on all my projects with VR enabled

Frequently, when starting the VR preview, the whole window freezes

I'm using the VR template on the current projects, but I also had this kind of freeze with a custom made template using the VR examples content package

anyone had something similar ?

[rocky nimbus]

I'm seeing this error when I open my project

My packaged game plays the video file on Oculus but not on Vive

The 2 files it's referencing in the MediaPlayer aren't actually in the media player

What's happening?

(It started when I upgraded the project from 4.16 to 4.18, some kind of cache?)

[wicked oak]

go back, and upgrade to 4.17 as intermediate

they did a lot of changes to media stuff, so no wonder stuff broke

usually its best to upgrade one version at a time

[rocky nimbus]

@wicked oak I deleted all the media-related assets in the MOVIES folder and re-imported, re-created the media player and the error doesn't show up on launch anymore. Hopefully Vive can see the video in the packaged ver.

[gleaming river]

Hey peeps, If I was wanting to sit in a real chair whilst in VR what would be the way to always know the location of that chair. Should I be using a vive tracker?

[jaunty shell]

@gleaming river yeap, or if you don't need both controllers, you can use one of em instead of a tracker

[gleaming river]

@jaunty shell Thanks, I will give it a go and see what happens :d

[jaunty shell]

feel free to report back 😃

[cold siren]

Hey guys, I'm trying to get a Light Fixture working in VR that has tweakable dimmer. My problem is that stationary lights start overlapping. I dont need the lights to cast dynamic shadows but I want other the properties of stationary lights like changing the intensity and colour. I turned off cast dynamic shadows in the lights, but the stationary lights still have X on them signifying overlapping. When I uncheck "cast Shadows" it works fine, but I now lose the shadows from the light fixture it self. Any one know how I can use the stationary light features but not have them be dynamic?

[wicked oak]

@cold siren bruh

thats ridiculous

for the love of god dont do that, it will run at 1 fps

use a emmisive material

and add one light to do the general lighting

[cold siren]

@wicked oak yeah obviously its performing poorly atm

my fundamental question was whether the features of stationary lights are all expensive? Dynamic shadows vs changing of intensity? I assumed (could be totally wrong) that the dynamic shadowing is the largest cost while changing intensity and colour have very low cost

is there a way I could use the latter 2 features and not the dynamic shadowing of a light? maybe through editing the engine?

[wicked oak]

stationary are very expensive

they are the same cost as fully dynamic lights

the difference is that their shadows are baked (for static shadows)

if you want "free cost" lights, use fully static ones

[cold siren]

ok so you are saying that stationary lights features are all the same cost as a dynamic lights except for parts that it can bake for static meshes

[wicked oak]

yes

[cold siren]

Ok so my best bet would be to change properties ina post process volume im guessing

@wicked oak I can't use one singular light for the space with emmisive material because I need these shadows cast by the light fixture itself

[jaunty shell]

how about faking it even more and using a light function ?

not that it will simple to translate it to a LF though, that's a lot of lights for a single fixture 😄

[cold siren]

Light Function, I didnt think of that

but maybe it could be possible

Aren't light functions expensive as well though?

[jaunty shell]

not really, its basically a texture projection

it'll be a lot less expensive than using multiple dynamic shadowed light for sure 😉

@pearl tangle @hard light @wicked oak Alright so I've made some progress with getting good performance with CAD imported models while keeping a way to get the individual entity Meta data available

I've setup the scene to only display the merged version of the model, and keep the "notmerged" model hidden

Raycasting is done on the hidden model, aswell as a highlight effect on the raycasted hidden part

performance is pretty good so far considering the scene is using dynamic lighting

still getting that nasty crash after a few seconds though, I've got no idea on how to debug that 😦

[hard light]

sounds like progress

[jaunty shell]

at least we're not talking about reprojection for each frame now, values are under 11ms 😂

[mighty carbon]

any idea how it's done https://twitter.com/grossbloy/status/962614315202371584 ?

Collin Harris ⚰ (@grossbloy)

so it turns out softbody physics objects are pretty satisfying in vr...

@mighty carbon flex nvidia branch ?

the softbodies in that tweet look quite similar

[mighty carbon]

hmm... I thought UE4 has soft bodies physics out of the box

[tired tree]

you are likely thinking of the faked soft body effect that people were pulling off with distance fields

[mighty carbon]

https://www.pico-interactive.com/neo

I wonder if Santa Cruz will cost about the same

(assuming specs are comparable)

[wicked oak]

that looks comparable in spec, except oculus is 4 cameras not 2, and has tracked controllers

the snapdragon and screen seem fairly comparable

[mighty carbon]

Pico claims controllers are 6DoF too

[mighty carbon]

I have a feeling UE4.19 will be released either tomorrow or on Wednesday

[tired tree]

sure hope not

[wicked oak]

@tired tree why?

i expect thursday

becouse its the typical release day

[tired tree]

still waiting on some bug fixes

fairly major ones

[mighty carbon]

there have been no commits to their repo for several days, and it's not due to bad weather

they haven't fixed multiview/direct crash either

[full junco]

my game is at "Very Positive", thats good 😄

@mighty carbon I know you disliked some stuff about the steam reviews, the only major issue I see with them is that people below min spec can write negative reviews. apart from that, I'm quite happy

[mighty carbon]

mine is very positive too, but before I became that way it was mixed... But, if you saw the link I posted a few days ago... Steam is a big dump.

and Valve isn't even trying to hide it

[full junco]

but you complained about the review system specifically a while ago

[mighty carbon]

yeah

just saying on top of that

you should release on Home and see if it gets more visibility than on Steam

for science 😃

[full junco]

no, thats not a place to release the game in the near future

its not made for early access

and I only have 25% rift users

[mighty carbon]

there is EA option when you release

[mighty carbon]

oh, just saw Oculus reply to my bug report and sounds like 4.19pre5 is on the table with multiview fix.

unless it was merged into p4 somehow

[granite jacinth]

Hmm, anyone have issues with players randomly freezing?

Seems like a Memory Leak

But this is a full BP project

Only thing I can think of is maybe some infitnite loop.

But it happens on both Rift and Vive and only started happening in 4.18

It doesn't happen to everyone

[sharp swan]

does the world free or just the player?

(freeze

btw. there is no harm in adding a custom c++ class to convert it to a c++ project and then using the debug symbols in VS to find out the issues. It's my main argument for not making blueprint only projects.

[noble crater]

anyone know if there's a way to get the HMD "eye" in a Material? I want to have a different stochastic seed per eye

looks like ScreenPosition could work

[sturdy coral]

@wicked oak @mighty carbon I think that (pico) is the same one you posted a few weeks ago. it was 6dof through using ultrasound if I remember right

@mighty carbon I don't think he can release on oculus home, don't you have to be compatible with the oculus min spec?

unless you are on gallery apps maybe?

[mighty carbon]

no, you don't have to be

and if you submit as EA game and get accepted, I think you end up in EA section of Home, not in the Gallery

I can only speak for mobile.. On mobile I would specify min spec platform and it would have to pass. For example, I said S6 is minimum (ignore Note 4) and that's what they would use for passing the bottom line

fortunately with multiview my project ran at 60 fps on Note 4 too , so I think they didn't black list Note 4

vblanco would be the one to ask about Home release on PC

[sturdy coral]

@mighty carbon hmm yeah Onward seems to be able the spec (recommended 980, not sure min), but is in that early access section

[proper osprey]

Do you guys know the best way to use mirror material in VR? Tried planar reflection, but it hits hard on the system and doesn't work properly with VR. On the Oculus Dreamdeck App there is a scene where they copied the room to the other side of the mirror mesh and it looks great. Is there a way to have a portal like mirror where I can create a copy of the room but making it so that it doesn't show the copy on the other side of the wall? It's for a bathroom in a house and the other side of the wall where the mirror is located is the kitchen.

[glossy agate]

@proper osprey You try scene capture cube? You can make it "reflect" anything. Im guessing you are doing arch viz, thats probably the easiest way

[proper osprey]

yeah I tried it. It doesnt work very well, it streches the reflection, and for some reason the scale is way bigger than the reflected mesh. I guess I will try it again and see what I can do with it

thanks!

[pearl tangle]

you have to mess around with the placement of the camera for that and the output resolution of the texture

[glossy agate]

Yeah and make sure it’s using Tex cord so it doesn’t run off the size of the mesh

[rocky nimbus]

@proper osprey As long as you don't see any moving parts in the reflection, a replica of the bathroom might work best performance-wise

A capture component doesn't work well in VR as a mirror because you're forcing a mono view through the mirror

[jaunty shell]

planar reflections work rather well with VR @rocky nimbus , but performance wise... that's another thing 😄

[rocky nimbus]

@jaunty shell Oh yeah, I meant just using a 2D capture component and then projecting the camera onto a flat surface

Is costly and would look 2D in VR

[jaunty shell]

yeah looks like ass for mirrors

[rocky nimbus]

I had to use it for a sniper scope and even then it looks like ass

[jaunty shell]

😄

well you could force the 2D capture to be displayed in one eye only

and have two of em

but then the frametime would go through the roof

[rocky nimbus]

Yeah, even with just one I had a hard time getting optimal FPS. Low-res, too

Basically rendering the scene 3 times or more when you start using 2d captures in VR

[mighty carbon]

has anyone here tried Teamviewer to work on your UE4 project from a lesser powerful device ?

(I'd love to work on my project from work, connecting to my home workstation where UE4 is running)

[real needle]

@mighty carbon Yes, using the tools are fine, but playing in editor with wasd + mouse = no

[jaunty shell]

also, scene view doesn't take long key presses @mighty carbon

if you want to move using wasd, you have to do multiple key presses to go forward for example

[mighty carbon]

gotcha

thanks

[jade saffron]

just came across something: a lot of vr games just come with generic video setting to choose from, mostly only graphic profiles (low, medium, high) and antialiasing level. is there any reason why you wouldn't want users to change more specific settings (e.g. shadow quality)?

[mighty carbon]

not VR, but crazy stuff https://dotesports.com/pubg/news/pubg-2-mobile-games-china-75-million-preorders-20968

I am sure mobile VR market in China will be lucrative with Oculus Go release

[mighty carbon]

btw, https://www.youtube.com/watch?v=y3F8F4Bt7kQ

cool if someone wants to make Wolf-like game for VR 😉

[wicked oak]

@mighty carbon i would do it, if i had any level design skill whatsoever (wich i dont)

[eternal inlet]

hi guys, im currently troubleshooting something which could be a loose connection with my vive, but which may actually not be the case

every time i start my game, it runs fine the first time

second time the HMD content is blank

if i issue a stat unit cmd, i can see it drops frames insanely

like 33ms

and if i then run r.screenpercentage 100 followed by 140, most of the time, i end up getting hmd image back

anyone know of this?

actually it seem to come and go kinda randomly

when i don't have anything running, i tend to get these spikes too

my cpu is i7 4990 + gtx1080ti

and gpu seem to be just ideling

[wicked oak]

could it be GC ?

[eternal inlet]

highly unlikely

it's ticking like every second

[wicked oak]

thats exactly what gc does

nearly every time its a spike every n seconds its gc

profile it?

[eternal inlet]

hmm, wouldn't i see it always then?

[wicked oak]

the profiler can see the spikes

[eternal inlet]

which profiler u mean? the one in ue4?

stat startfile thing?

[wicked oak]

yes

[eternal inlet]

ok

well, i just found out that if i put down my hmd, it starts with the spiking

but if i put it on, and it shows the steamvr home garden, it runs smooth

how odd is that?!?

never had this issue before... pretty stumped

[mighty carbon]

https://uploadvr.com/qualcomm-reveals-snapdragon-845-performance/

[glossy agate]

Maybe a problem with "worn state"?

[eternal inlet]

it does seem like it

but why? i don't recall changing anything recently... it just started all of a sudden

[mighty carbon]

I hope Santa Cruz will have 845 inside

[granite jacinth]

@mighty carbon I thought I saw it won't

845 is the latest right?

[wicked oak]

maybe it even uses a semicustom chip

but something like that snapdragon makes sense

[mighty carbon]

@granite jacinth Go uses 820.. There is no reason for Santa Cruz not to use 845 and beyond - they don't have to fit into $200 budget

[eternal inlet]

profiling didn't show up anything usefull other than 30-33ms stalls

so i tried switching on reprojection, and then it went back to normal

i've been running without reprojection enabled (any of them) for atleast 2 months now, i wonder what causes this now... 🤔

well, almost goes away... it's just much less

still does some odd hitches

[mighty carbon]

https://www.reddit.com/r/oculus/comments/7xc9hx/steamvr_update_for_21318/

[mighty carbon]

UE4 needs this https://www.youtube.com/watch?v=shcAvnYp9ow

I think I'll use it for my projects 😄

[glossy agate]

They came out with the fancy new geo editing tool early last year.

has all the extrude, bevel, slice ect. Probably OK for blocking out, but I don't know about using it for a modern looking game

[mighty carbon]

CoD series still use same old BSP levels with decorative meshes

the core is blocked out with BSP brushes anyway

and TrenchBroom allows such blockout to be done with unprecedented speed

it would be nice to have the design flow and tools like that built-in, in UE4

[wicked oak]

@mighty carbon that does look good

cant you export it to obj or whatever?

there is HammerUE wich can load hammer maps, maybe that could owrk

[glossy agate]

Reminds me of the old "red faction" level editor that came with the game back in like 2001. Was so fun, and it had procedural destruction for all meshes if you wanted

[wicked oak]

@mighty carbon can you use it to do ue4 maps?

their BSP CSG stuff would be of use to me

for prototype geometry

blender and houdini are both kind of crappy with booleanspam, so doing CSG is a lot more annoying for greybox type stuff

[mighty carbon]

@wicked oak you can make Quake map, and then import it to UE4 using HammUer plugin

[wicked oak]

that sounds interesting

i should test it

[mighty carbon]

I don't know about OBJ.. Kinda defeats the purpose of brushes

[wicked oak]

ill try that editor, and if i like its workflow ill try hammuer

just for greyboxing

[sturdy coral]

@eternal inlet GC shouldn't happen every second so I don't think it is that. many people have reported issues with MSI afterburner causing stalls every second

[eternal inlet]

i ended up reinstalling my entire pc actually

it was acting really weird

so i suppose those stalls were related to that

[sturdy coral]

if you do have afterburner, people say to make sure to close the monitoring graphs that show GPU temp and stuff while in vr

[eternal inlet]

ok

[sturdy coral]

or every time it polls it it causes a hitch

[eternal inlet]

noted

hm i don't even know what afterburner is

[sturdy coral]

it is just an overclocking utility

[eternal inlet]

ah, i don't have that then

[sturdy coral]

they say other apps that monitor gpu temp etc. can do it too

[eternal inlet]

im almost done with re-install now, so it's hopefully gone then

[sturdy coral]

I think GC happens every 60 seconds by default

unless you run into memory pressure and it needs to run earlier

[eternal inlet]

yeah, i've seen it run about once every minute too

[sturdy coral]

I never got around to it but it would be nice to have GC happen during click turns and a few other events like that

maybe bias it to prefer running when the character or hmd isn't moving much too

[eternal inlet]

that would be nice yes

[granite jacinth]

hmm

I use 2017 no problem. It should compile any 2015 stuff no problem

But Im no expert on VS

[real needle]

@eternal inlet Yeah I didn't have any problems switching to 2017, it still compiles the project as 2015

[eternal inlet]

oki, i'll go with then too then i think

[supple lotus]

Hey everyone! Anyone has ever met the issue, where you have a mesh (character) position and rotation set via the HMD, but in the game they end up at a different spot, compared to the actual HMD position?

In our CharacterBP, the camera component is bound to the HMD, and then the character location/rotation is set based on the camera pos/rot. We are printing the HMD location/rotation, and it shows different values than the actual actor loc/pos. For instance, the HMD says the location is x= 50, y= -90 and z = 0, but the mesh ends up on the x=50, y=-86 z=0. If we move around, we get the movement relative to the wrong mesh location, and not relative to the actual game center. Any ideas?

[glossy agate]

Still on the struggle bus with this. So here is the vid when I kill the player with a hot key. https://youtu.be/zMAEqwJ7Dzw

Kill logic

just putting the mesh back in the respawn sequence

Im using the BIK plugin but every other disconnect works fine with diff anim states. With physics though I disconnect and simulate the whole thing, there is a floating crucified mesh flashing. Any idea what Im doing wrong? Have tried a bunch of stuff

Well one part solved. on detach I needed keep world, so no floating mesh. Now its just a flashing mesh on the ground

[granite jacinth]

Who has received a WMR Dev Kit, and do they remember if it came from Vegas?

[ripe vault]

Curious if anyone else has had problems with vr preview working in UE4 4.14 or 4.15 with latest oculus version?

[sturdy coral]

@glossy agate have you tested the same mesh without bik? make sure the physics asset is good in a simple project

[glossy agate]

Didn’t have it before bik or any other game. Hostages have the same phys asset and they work fine

[sturdy coral]

@glossy agate shooter game does:

GetMesh()->SetSimulatePhysics(true);
GetMesh()->WakeAllRigidBodies();
GetMesh()->bBlendPhysics = true;

[glossy agate]

Hmm I’ll look at that blend. I simulated from spine up with no flashing, but all the way to root makes it flash

Hello Everyone, If I model a box that represents a box in real life and I want to walk around the box in both VR and real life, how do I make sure I spawn in the correct location in VR to what I am putting my headset on in the real world?

[main ether]

you need to know where the box is in relation to your tracking volume

if you dont have that, then you can let the user touch the box with the controllers or the hmd to get the location

Guys, I'm trying to resemble the feeling of a slow-mo in VR. Thinking of adding a delay to my Motion controllers to get this feeling ... just wondering how I can possibly do this with blueprints ?!

[shell karma]

you want to slow mo the controllers or the environment ?

[mighty carbon]

eeeh, you control your own time.. If you want for your hands in VR to do slo-mo, then move slowly

otherwise there will be disconnect between your physical movement and the hands you see in VR

[shell karma]

even if you'd come up with a way to force slow the controllers that'd be very bad decision, design wise, can't force real person to slow their movements based on slow movement in game

slow motion feels great with everything around you slowing down, ie actors, enviro etc

[dusky moon]

well enviroment wise it's easy to do so

but I would like to test the slowmo on the controllers

it's for a research

so the desync doesnt matter honestly

[shell karma]

you'd then have to do it manually every frame then

I mean controller world transform

[dusky moon]

like I should do it on Event Tick using VInterp to ?!

[shell karma]

I'm afraid you'd have to dig deeper into MotionControllerComponent

which is c++ and engine source

[dusky moon]

Oh well, sounds scary ... but will try

[shell karma]

well basically what I can imagine is that you'd perform some normal/fast movement of your arms and then your hands in VR would slowly follow the route to some extent. Still can't understand why, player would just stand and watch the hands moving

[dusky moon]

the thing is ... I want to test how if actually feels in VR. so you can watch the trace of you bodily movements. but it may feel very wrong though

[shell karma]

well you could always came up with some sort of movement recording feature, you'd save world transform of a desired component and play it back at some point

[dusky moon]

True, it's already possible to record movements with sequencer. hope it was possible to use it on run-time though

[shell karma]

not sure about sequencer, but I've seen some time shifting blueprint stuff on the marketplace, it might have something useful for your case

[dusky moon]

ah cool, will check .. thanks man!

[shell karma]

https://www.unrealengine.com/marketplace/reversing-time-system

cheap as hell so might be worth looking into

[dusky moon]

Wow seems super cool! even if it didn't work with Motioncontrollers ... already great for actors!

When you are running steam VR room setup does pointing at the computer screen and pulling the trigger affect the direction in which my HMD will face.

[proper osprey]

Hey, how do you guys deal with this? If I change RecastNavMesh setting it breaks teleportation

I want to have collision on walls because of physics objects

[glossy agate]

@proper osprey There is an "agent radius" or something like that you can adjust for more precision

[proper osprey]

unfortunaly if I touch it it breaks teleportation. I tried doing it directly on the project settings and it doesnt look good

"A latency reduction for late-update has been integrated into this release. This is particularly helpful for Oculus mobile platforms."

@wicked oak ^^

[proper osprey]

Found a fix. I changed runtime generation to dynamic. Though I don`t know yet how bad this is for performance

Agent radius has a bug that apparently isnt fixed yet

[mighty carbon]

report it.. otherwise no one will fix it

[glossy agate]

Is the scale of everything super small in your level or something?

Like one of the rooms isn't even getting any nav mesh

[proper osprey]

the scale is right. Im building an apartment using real world scale. I used UBX for wall collision. And the bug has been reported by other users already. Over a year ago. That's how I found out the fixz

[mighty carbon]

care to share a link to the fix?

I use that setup for my open world level

(with navInvoker component added to player's character)

@dusky moon You don't have to dig into motioncontroller component, just move a different component towards the location of motioncontroller etc

You shouldn't offset the motioncontroller component other than for debug afaik

I wonder what DX11 quad buffer stereo rendering is and what effects it has? @tired tree @sturdy coral

[tired tree]

Its for CAD

falls in line with all of the CAD work they have been doing as well

[full junco]

what CAD work?

[tired tree]

at least tradionally, doubt this is for VR in this case

3D stereo

for 3d monitors

[full junco]

anyone uses 3d monitors?

I thought 3d on monitors is dead

[tired tree]

I used to for work, in CAD :p

it was,.....meh, got rid of it eventually

[full junco]

ok

I just tried the temporal upsampling in 4.19 for the first time

its really way better than I thought

and crazy expensive 😄

1.4 ms just for the upsampling

and its not listed in stat gpu

(bug)

when reducing the TAA samples from 8 to 1 it honestly doesn't look much worse, and the TAA upsampling time is down to 0.6 ms

1 sample looks way worse on a still screenshot, but when you have the headset on your head the minimal movements you make are enough so that the image looks way better

[mighty carbon]

why don't you use forward + MSAA @full junco ?

[full junco]

because I need SSAO

and with the new TAA upsampling TAA is way nicer anyways

screen percentage 40 with the TAA upsampling really looks essentially same like screen percentage 100

but I also havent yet tested with foliage

I guess the biggest problem will be something like the sky

[mighty carbon]

I see

[pearl tangle]

anybody got the samsung odyssey headset?

[full junco]

I asked MS for any WMR devkit 3 weeks ago and they have not reponded at all...

[pearl tangle]

ah yeah you need to go tothe manufacturer for that. Lenovo will give you some

[full junco]

I do?

I thought that form from MS is the way to go

[pearl tangle]

Dell also was giving some out to developers as well i know

well yeah thats the general entry point to it, but usually not the best or fastest. Lenovo loaned us a bunch of free equipment for some museum exhibit stuff I did and via google I am getting their standalone headset in a few weeks. Just gotta show them some project stuff that will sell hardware for them or get them good PR and they are all over it. Microsoft is big and slow

[full junco]

does samsung send out odysseys?

[pearl tangle]

Samsung is shit. They are my client and we do millions of $ worth of work for them each year, even do the advertising campaigns for their phones. And they wont even tell us anything about the phone beforehand or send us 1 hah

can't get anything out of them. I just ordered 5 of them through the microsoft store since they are on sale, have to get them sent to my chicago office and then posted over here though. At least less tax to send to chicago office rather than new york office

[full junco]

well its understandable they dont want any info to be leaked..

[pearl tangle]

we had to install a secure fingerprinted room with no internet and have a security guard that stands outside to check everybody. Not even allowed to have paper in the room. And this is just for doing stuff that doesn't even show anything about the phone

the information we have to go on is leaks from internal 1s that are all over the internet anyway and they pretty much just advise us to go and google the stuff since they already know it will have been leaked

[full junco]

ok 😄

well the odyssey doesn't ship to europe

[pearl tangle]

nor to singapore

[full junco]

I dont get why they limit it that way

[pearl tangle]

test markets first, it's an experiment rather than a full product launch

even Oculus doesn't ship to Singapore yet

but facebook her is desperate to try and get it. I am in talks with them about doing stuff in china for it at the moment which is rather interesting

[full junco]

ok

[pearl tangle]

not sure why they don't ship to singapore still. Only took vive about 6 months to start doing it, and now Singapore was the first market where they were doing developer outreach on the vive pro

[full junco]

how can I get htc to send me a vive pro? 😄

[pearl tangle]

where are you based?

[full junco]

germany

[pearl tangle]

ok their europe head is based down in Barcelona. I have his business card around here somewhere will try and dig it up later.

they wont send you 1 for free but they have told me they will sell to me at cost

[full junco]

my game looks great, has very positive reviews, they should be willing to send me hardware

thanks!

[pearl tangle]

not the vive pro. They aren't trying to sell that to consumers. It's too expensive. It is their replacement for the business edition version

hows the sales going for your game anyways?

[full junco]

I guess good 😄

I primarly care about having an active community, and that I have

[pearl tangle]

what did you end up calling it?

ah cyubeVR

[full junco]

yeah

[mighty carbon]

@pearl tangle got any info about any GearVR products in 2018?

[pearl tangle]

@full junco so around 3500-4000 odd sales?

@mighty carbon I think you should just give up on GearVR hah. Im sure they will probably update it with S9 but dunno. They should try and make it on the A series and J series would be a good idea, the specs are pretty damn similar to the S series anyway

[mighty carbon]

they already made it on A

well, it's not that I am haven't given up on it, I just want to know if it will continue to drag on

(I wonder if they kill it off when Go is out officially)

[pearl tangle]

Go isn't done by Samsung though it's just Oculus on their own. Samsung likes to try and take ownership across the board for things. That's why they keep fucking with android so much and try to push samsung pay instead of android pay, bixby instead of assistant and a range of other garbage software. They are good at hardware but their software is terrible

[mighty carbon]

well, with Go no requiring phone and being overall better than Gear VR and at $200, I don't see who will be buying Gear VR

Bixby... lol.. I hate that assistant .. Dumb is a rock

it seems like it doesn't even understand English

[pearl tangle]

yeah google has had years of figuring stuff out with voice, samsung is starting from scratch. It took google 5 years before it got half decent

[sturdy coral]

@full junco they should probably reduce the neighborhiod samples if you are running at 1.0 and increase when running lower, if they don't already. Maybe even entirely use the old shader at 1.0

[full junco]

@sturdy coral I have tested foliage with wind now, and that does indeed look quite bad

[sturdy coral]

@full junco ah, yeah I thought it probably would. Anything where taa rejects the history is going to look bad probably at really low base resolutions

If you could make velocity buffer run at full res instead of half it might be better, but then way more expensive when running near target res

[full junco]

@sturdy coral I'm not sure if a higher res velocity buffer would really improve it..

[sturdy coral]

@full junco how is grass with wind turned off? (Turn off velocity in the material too so it uses depth*camera change)

[full junco]

@sturdy coral with wind turned off it looks great

I'm not testing grass, I'm testing trees

@sturdy coral also, changing the screen percentage is still doing reallocate for the render targets every time

it prints LogRenderer: Reallocating scene render targets to support XxY Format 26 NumSamples 1 (Frame:2214). in the log after every SP change

@tired tree why did you delete what you wrote? 😄

[sturdy coral]

It probably doesn't reallocate in 2d when dynamic res management is on, it may require something like your old patch but not as involved

@full junco There is an r. something setting to change the reallocation policy somewhere, but I think we found it didn't work in vr before on earlier versions

[full junco]

in 4.15 there was no way to change any "reallocation policy"

[sturdy coral]

@full junco this was what I was thinking of, it was in 4.15

    TEXT("r.SceneRenderTargetResizeMethod"),
    0,
    TEXT("Control the scene render target resize method:\n")
    TEXT("(This value is only used in game mode and on windowing platforms.)\n")
    TEXT("0: Resize to match requested render size (Default) (Least memory use, can cause stalls when size changes e.g. ScreenPercentage)\n")
    TEXT("1: Fixed to screen resolution.\n")
    TEXT("2: Expands to encompass the largest requested render dimension. (Most memory use, least prone to allocation stalls.)"),    
    ECVF_RenderThreadSafe
    );```

it might have only applied to scene captures or shadows or something

[full junco]

ah

[sturdy coral]

it does mention screen resolution

it is still there in 4.18, you could try setting it

I don't think it helped any with hitches on 4.15 etc. though

[full junco]

ok

@sturdy coral doesnt change anything to set it to 2

[sturdy coral]

weird

@full junco this is the guy who did most of the commits on it I think: https://forums.unrealengine.com/member/35222-guillaume-abadie , maybe message him or mention in the 4.19 thread

[eternal inlet]

looks super cool @full junco

[full junco]

@sturdy coral that might actually be a good idea

@eternal inlet thanks! 😃

[eternal inlet]

anyone with a vive or oculus that would like to participate in some testing of my game, pls DM me

https://www.youtube.com/watch?v=Cnx2syPSTHk

[tired tree]

@full junco worded it terribly and realized no-one probably understood what I meant :p

was heading to bed

and yeah, 2 on that CVAR is what I was talking about

if it is going to hit the max res ever, then why not stick with that size render buffer to avoid allocation

its not really saving memory in the end since its going to require it at some point anyway

granted, maybe it already works like that normally like MuchCharles is saying

[fleet plume]

@eternal inlet what are you using for the floating menu (as seen in the screenshot above)? StereoLayer + UMG?

[eternal inlet]

3dwidgets and UMG

[fleet plume]

i tried 3d widgets some time ago but something bothered me. it was either that they weren't as sharp as a stereolayer and/or that they were affected by post processing

can't remember which one

yours are looking great, so maybe i should give them another try 😃

[eternal inlet]

i think they're fine yes

i run with 140ss, in the video, which is sort of the default for vive

[fleet plume]

i probably did something wrong when using them

also, the waypoint/distance beacons are 3d widgets too?

[eternal inlet]

they're actually planes

placed and scaled according to the target + the HMD looking direction

so the arrow will place itself at the same distance as the target is

i have two planes

one semitransparent ignoring zdepth

and one solid with occlusion

[fleet plume]

thanks for the detailed explanation! just starting out with ue4/vr/c++ so glad for any pointers

[jaunty shell]

oh damn @granite jacinth you guys are looking for a tech artist ? 😮

[mighty carbon]

hmm.. no github updates, no news, no releases.. Is Epic waiting for GDC to release 4.19?

[jaunty shell]

that's in a month 😦

[granite jacinth]

@jaunty shell Always looking for quality

[jaunty shell]

I'd apply if I wasn't tied to my current job :p

how many lads do you have in your team so far ?

[mighty carbon]

what's the optimal way to go about first person weapons? Would it be better to spawn and attach weapon as BP_Actor on weapon pick-up/switch, or would it be better to just have all the meshes for weapons lined up and attacked inside player's character and hide/show them when needed ?

not UE4, but makes sense.. https://blogs.unity3d.com/2018/02/15/probuilder-joins-unity-offering-integrated-in-editor-advanced-level-design/

[sturdy coral]

@fleet plume they aren't as sharp (in world UI vs stereo layers); if you are using TAA you can set them to use responsive AA in the material to make them sharper; has to bea translucent material for that and it will make everything behind it aliased, but you can put opacity at 100% to avoid that mostly

@mighty carbon the "optimal" way for performance is maybe to combine the weapon meshes with the player meshes at runtime but it would make your asset pipeline more difficult

shooter game uses separate weapon actors for each weapon

and inside the weapon actor there are multiple meshes, but that is mainly for supporting split screen

[fleet plume]

i disabled TAA for now, as i show debug graphs on a CanvasRenderTarget2D and the overdraw (?) made it gross to look at

[glossy agate]

@mighty carbon gun logic can get complicated. I just have separate actors for weapons

[fleet plume]

does the forward renderer even support TAA?

[sturdy coral]

@mighty carbon shooter game has two so it can have first person OnlyOwnerSee, split screen third person OwnerNoSee

@fleet plume yeah it supports it

[glossy agate]

And like Charles said some of the actions on my weapons use relative space so it wouldn’t work inside the pawn

[sturdy coral]

I don't know if it supports the responsive AA flag in forward though

there are various things missing in forward rendering in different places, responsive AA uses a stencil bit somewhere

[fleet plume]

i got that right though, that the forward renderer is the preferred renderer for VR?

[sturdy coral]

yeah seems to be for most people

[glossy agate]

It has better perf and supports msaa so people like it.

I’m still on deferred though. Will have to re work a ton of materials to support forward so I haven’t done it

[sturdy coral]

@fleet plume stereo layers are still going to be a bit clearer in general, the compositor can run at a different resolution and the layers can be rendered after timewarp on some platforms which can avoid timewarp resampling

[fleet plume]

though MSAA looks worse than TAA imho

[sturdy coral]

I use TAA, it adds blur but it is just more compatible with lots more assets

[fleet plume]

i haven't fiddled with any options (there are none in the rendering options?!)

would super sampling help with reducing aliasing?

[sturdy coral]

@fleet plume yeah

TAA basically super samples, accumulated over multiple frames, but ends up blurring some too for several reasons

but you can also directly supersample with TAA and MSAA, at much higher cost

if most of your aliasing is from polygon silhouettes and not shader aliasing a higher MSAA sampling rate is much more efficient than supersampling though

[fleet plume]

SS would be r.screenPercentage and MSAA quality r.MSAACount ?

how does r.PostProcessAAQuality play into that?

[sturdy coral]

yeah that's it

[mighty carbon]

I see

[sturdy coral]

postprocessaaquality doesn't do much, I think it moves TAA into different sample numbers and jitter patterns, but there is no real cost to doing the highest quality gaussian random jitter thing

[mighty carbon]

I guess pickup actor would have it's own model (world model, so to speak) and player could have view model. World model would be simplified compare to view model and would be used on 3-rd person player's model (that's if I ever go with multiplayer).

[sturdy coral]

it might be something you want to tweak if you are also tweaking the TAA history contribution and stuff. it all probably changes a bit in 4.19 with the new temporal upsampling stuff too

[fleet plume]

any recommendations for sensible MSAACount values?
(i wish the console would have inbuilt help :))

[sturdy coral]

aaquality might do more on other AA types, FXAA and stuff.

@fleet plume I think 4 is the highest it will go and I would use that

[glossy agate]

Let the player pick if you can

[sturdy coral]

MSAA is a good one to change dynamically too

[fleet plume]

depending on fps?

[sturdy coral]

it is less jarring with msaa to drop from 4 to 2 samples msaa and back than to drop resolution

[fleet plume]

ah ok

[eternal inlet]

i still have issues with my vive, would like to hear if any of you have suggestions to what else i can try. I've written down some notes

Symptoms:

• when loading any game, the blue loading screen jitter around when i move my head from side to side, like i got really bad FPS
• when starting up ue4, sometimes it runs with 11ms, but usally subsequent starts of a game, results in 33ms
• when running 33ms, i can switch to console and as soon as i type in r, it switches back to 11ms
• when running 33ms, and it doesn't switch to 11ms when i type r, i can switch r.screenpercentage 139 (anything different from what it was) and it will switch to 11ms
• when the hmd goes idle, it will show a spike in the performance viewer in steamvr every second

This is what i've tried:

Reinstalled PC
Tried with different gfx drivers

• 390.77
• 390.65
• 388.71
  Tried bypassing cable
  Tried different USB ports (several hubs)
  Tried different ue4 versions
  Tried both SteamVR and beta

...and problem persists in all scenarios

[sturdy coral]

@fleet plume taa can smooth over resolution changes really well, but requires a patch to the code; 4.19's taa upsampling stuff will make it even better but res changes with it aren't fully working in VR yet without hitching

[fleet plume]

thanks! also looking forward to 4.19 now 😃

[glossy agate]

Anyone else reporting the problem? @eternal inlet I can giv it a try tonight, but I havnt had any problems with your game before

[sturdy coral]

@eternal inlet which engine version?

oh sorry I see you tried multiple

[eternal inlet]

ah sry, i tried with all recent versions, 4.16, 4.17, 4.18, 4.19preview

im quite sure it's not hardware related (or not only atleast), since i can touch things in ue4 for example to get it to switch to normal

but it might be hardware on a lower level, but HTC support said all the system info was looking good

[fleet plume]

could it be focus related? when i am running PIE in VR and the game loses focus, the log gets hammered with compositor warnings

[eternal inlet]

don't seem to be focus related no, i can see my controlers move and can interact with stuff

[fleet plume]

also some motherboards have a specific BIOS flashback USB port and somebody on reddit reported problems with the vive when using that port

[eternal inlet]

@glossy agate that would be nice if u could... just note, i also just added in ikinema solver for the sniper, so that might have an effect on performance. Fantasiful reported it was killing FPS for him on oculus atleast
