can you manually do stuff when the late tick for the motion controllers happens?
like, moving other components too?
pearl tangle
If you attach it to the motion controller I guess
full junco
well yeah, but thats not what I want
I've just looked at the code and it should be possible to add other components there
pearl tangle
Maybe cast the tick from the motion controller to your other actor?
sturdy coral
do motion controllers get a late tick? I thought they just got a late pose update in the scene graph
pearl tangle
Yeah I was thinking it was something along those lines too but haven't really dug into it

very cool!
does anyone know how I can turn off Oculus reprojection so that I can profile without it getting in the way?
pearl tangle
Should be able to in the oculus settings I think
real needle
@pearl tangle I like how they rigged the real world space for Front Defense. If I had a garage and space I'd made a nest out of papier mache, and had everyone demo inside it
Were there "regular" vive stations with a selection from Viveport?
There's something about empty VR booths, they don't look compelling at all
pearl tangle
they had some other bits up the back which looked like you could just rent out and play for a set amount per hour or something
the whole setup like that definitely reminded me of something that would work well with the nest @real needle once they have the trackers and proper guns would be really good with the arcades
surprised the didn't green screen behind it though like they did in the other area
raven halo
@pearl tangle I couldn't find any option in the Oculus app to turn the reprojection off
pearl tangle
ah maybe its not possible with the rift like it is on vive
full junco
@pearl tangle @sturdy coral it only updates the transform, yeah. no tick
pearl tangle
Could you create a cast whenever it updates and use that as the tick essentially?
full junco
@pearl tangle I don't really get what you mean?
pearl tangle
Take the update event from the controller and cast that to your actor every time it updates and you have a new tick essentially
full junco
it doesn't make sense to me what you say, so I have no idea what you mean
what update event you talk about?
and what should I cast to my actor there?
pearl tangle
If the late update event in there is doing something (it's transform) as you mentioned. All you have to do is create another action after that. So instead of having a tick event in your other actor you create a custom event, "Tick and Morty" I shall call it or TM. Just cast to your actor and call TM every time the late update transform change happens and you have created a tick event that matches with it
full junco
@pearl tangle I dont think that works, since it can only modify the transforms. anything else than updating transforms will not work, the stuff basically runs from the render thread I think
pearl tangle
Well there has to be something going on there that's making it happen so there would be a way to tap into it
full junco
its calculating an offset to the transform thats then used during rendering, its very specifc setup for that reason
for anyone using temporal AA in VR, this small change helps a lot I think: https://forums.unrealengine.com/showthread.php?134157-Sharp-Temporal-AA

cobalt relic
I wish there were more stuff exposed to variables
UE4 lacks some configuration options as far as rendering go
full junco
yeah, but changing a variable in a shader file is fine, it takes like less than a second to apply that
and people who aren't on a source build can also do it
mighty carbon
supposedly they again will have 2 versions of the phone, Snapdragon and Exynos
850Mtri/s and 27.2Gpix/s
vs 1700Mtri/s, 13.6Gpix/s on S7
downgrade ? :/
good thing is that G71 also supports 120Hz refresh rates, which might make it painful to maintain on mobile device for VR 😦
noble crater
people with complex UI attached to each motion controller + logical dependencies between them - how are you structuring the code?
graceful junco
That's a very broad question. Can you specify?
noble crater
im planning to do something like this
FSM=finite state machine
for me hands have mostly same functionality, and then I have some multi-touch interactions. currently doing everything at pawn level which is total mess
graceful junco
I started with all my logic in the pawn, too. Also realized that's messy :D. Now I just have a hand BP, which has all the logic. Each motion controller component in the character has one hand BP as child actor component.
Input is handled in the player controller. I have one input event for "grab" for example. The player controller checks, if the pressed button was on the right controller or left controller and calls the grab event in the appropriate hand actor component.
noble crater
makes sense, sounds like the same idea. any reason to prefer child actor components to regular actorcomponents?
graceful junco
Cause a component can't have additional components.
You can have one BP, which has your controller mesh (oculus/vive controller), additional meshes like a laser, widgets, lights, etc. You use that as child actor component for each motion controller.
granite jacinth
20% HDK2
graceful junco
You can also mirror the mesh and other components like the widgets in the hand BP, based on a bool.
So no need to create a second BP for the other hand
noble crater
@graceful junco ahh I have component trees in a few parts of my app, always found it problematic (esp. initiailization) and wondered if it was officially supported
sounds like child actors are the way to go
graceful junco
Epic just recently added a way to edit child actor variables through child actor templates. Wasn't really possible to do it this way before.

@granite jacinth thanks man.
mighty carbon
btw, what's the difference between Event Dispatchers and BP Interfaces ?
wise thunder
They're like, completely different things, no? Event dispatchers are like delegates, you bind an event to another event's fire (like subscribing)... BP interfaces let you simulate multi-inheritence, where normally unrelated items can be referred to by one type
mighty carbon
(I use BP Interfaces to call custom even simultaneously in different BPs)
wise thunder
But you're calling events onto specific references?
mighty carbon
For example, I when I press "I" in player's BP, it calls event in the Inventory BP, which is an entirely different class than player
wise thunder
But you're getting that reference from somewhere, right? Or else I might be misunderstanding how BP interfaces work, I haven't used them
Kinda just going off of what interfaces typically are 😛
mighty carbon
I gotta check my code (at work right now). I might be casting to inventory actor
wise thunder
Well, you'd still have to get it somehow I presume
mighty carbon
get what ?
wise thunder
The inventory
Dispatchers allow you to listen for an event rather than have it specifically called onto an object
It's just a different design pattern. It has its uses, like it allows you to scale architecure well if you have one thing that has to trigger a lot of other things
Instead of going back and calling like 10 functions on the original event, you just set up a binding for the event
Which also lends itself to black-box type inheritance...you don't have to modify the parent for everything
full junco
@midnight tree there are some bugs in ue4 sometimes that cause your game to look different in packaged
not really related to VR though, those bugs appear in all kind of games
midnight tree
ah ok

only thing you can do is regularly package your game so that you know what causes something to break in packaged
full junco
good 😄
granite jacinth
@mighty carbon @wise thunder spend a few hours on this...and you'll be amazed at what you'll learn. trust me.
**10 out of 10 Pro UE4 Devs recommended. **
wise thunder
Am I misunderstanding how the interfaces work in BP? I just assumed they were similar to regular interfaces like in C++
I know there's the "message call" which allows you to forgo the casting step, but I'd never noticed any other real differences
full junco
@granite jacinth for beginners thats good to watch, but not really for anyone who has ever touched an object oriented programming language before
blueprint just works like c++ mostly
and I don't really like interfaces in BP, I like to just keep references to stuff
with inheritance

Yeah, I mean if I'm missing something I'd want to know, but I feel I've got it down pretty well at this point 😛

VR Updates:
- The PlayStationⓇVR Aim Controller is now supported through the new AimController plugin. To activate, simply change the “Hand” value to “Gun” on your Motion Controller component.
- (Experimental) Monoscopic Far Field Rendering for mobile VR is available for testing. With content that has many distant objects, this can benefit performance. To enable, select the checkbox under Project Settings -> Rendering -> VR. We don’t currently support both mobile multi-view and monoscopic far field simultaneously and mobile HDR needs to be disabled.
nice!
full junco
would that monoscopic rendering also work on desktop vr or is there any technical reason why it would only work on mobile vr?
granite jacinth
about time

@full junco afaik it's mobile-only

aw man, only for mobile?
it would be great on my game
raven halo
"PreviousFrameSwitch has been added to allow specific overrides for world-position offsets in complex materials used during motion vector generation."
omg
this is big
does this mean I can access the previous frame's vert position? 😮
granite jacinth
@raven halo Please elaborate on its use in VR?
raven halo
If I can access the vert's previous position you can probably do stuff like ubisoft's eagle flight, I can't remember the term, but essentially they would darken parts where a certain amount of motion was detected
raven halo
but camera velocity is not all that is taken into consideration
at least that was my understanding
admittedly, I haven't taken the time to look very much into it. But I was under that impression.
btw
someone here mentioned the other day that turning on MobileHDR for GearVR halved the fps
however, another thing is true and that is the fact that the scalability is by default set to be very high
so things like bloomquality or tonemap quality can be pushed way down
I'm still experimenting with it
mighty carbon
@raven halo please let us know if you manage to get mobile HDR working at 60 fps. I have scalability set to low for post process and all that stuff, but it doesn't seem to affect performance on Gear VR at all.
raven halo
ok, will do

if anyone uses that vr.SteamVR.UsePostInit that gives 1ms more performance for the vive, it's not yet in 4.15 for some reason, only in 4.14: https://github.com/EpicGames/UnrealEngine/commit/af9d6262473492e4e9850133a128c95663ebb5be

hey @full junco I just stumbled across this:
https://forums.unrealengine.com/showthread.php?126528-Reduce-bloom-quality-to-a-single-gaussian-blur
did you personally try out what Konflict did?
I'm looking into optimizing the bloom for my little gearvr experiment further
so many downsamples seems like overkill
it's even doing them for mobile
full junco
@raven halo I didn't, he didn't really say exactly what he changed to make it work, and I tried for hours to get it to work and it just didn't (before he showed his screenshot) and then I didn't want to mess around with it any more...
so I just disabled bloom
I wanted to come back to it and try it out later though
wicked oak
that would be great for me
for VR
i want to use bloom
its one of the few postprocess that actually looks good in VR
but muh performance
full junco
@wicked oak yeah
on Konflicts screenshot its only 0.07 ms though
after he did those changes
but its just the editor preview window, vive probably has twice the resolution, so it would be more like 0.14 ms
still fine
wicked oak
gonna test it myself
becouse i have bloom disabled and it hurts my soul
i want those shiny eyes and shiny bullets
full junco
yeah
bloom is one of the things that clearly distinguishes a ue4 game from a unity one 😛
raven halo
@wicked oak if you test it out please let us know how what are the specific changes we have to do
I think I'm going to bump the thread and ask the guy
another thing I want to dig into is the tonemapper. There are different ones and I wonder which one is the cheapest
full junco
@raven halo there are different ones? 🤔
raven halo
yeah, check out r.Tonemapper.
you'll see the auto complete lists different ones
and I do recall seeing in the shader files different functions with different types of tonemappers
but only one of them is turned on by default
I don't even think you can choose between them from any user interface
it's just the command line
I haven't looked into it further, but it's in my to do list.
I'm willing to bet that the current one is also overkill
mighty carbon
@raven halo btw, mobile HDR with all effects off cuts fps in half.
it's performance taxing by itself, regardless of scalability and post processing features
raven halo
where does performance go, though?
I have it running at 60fps now with just the tonemapper. And for shaders I'm doing unlit + LogLuma encoded lightmap that I rendered in 3dsmax.
I'm trying to get bloom in there
raven halo
is mobileHDR not supported for GearVR at all?
what about people in the forums claiming it work on google daydream?
mighty carbon
Lightmaps is not just shadows/bounced light on the level. It's also lighting on dynamic actors. If you simply bake lightmaps in 3D app, it will not provide any lighting for your dynamic actors
it's supported - just performance taxing
it used to not work at all on Gear VR. Now it works, but it's slow.
raven halo
in my specific case the lightmaps are not an issue, I can handle the shading of the dynamic objects on my own and have custom lightmaps rendered externally
full junco
@wicked oak if you do the bloom stuff before I do it tell me if you have it working 😃
mighty carbon
we'll see what Oculus has to say
full junco
@mighty carbon @raven halo have you seen the new shader permutation reduction settings for mobile in 4.15?
mighty carbon
no, what does it mean ?
raven halo
I haven't yet
full junco
performance
in 4.14 only this existed: http://puu.sh/tpNm6/27eee4b2fd.png
thats still there in 4.15, just the extra section for mobile got added
raven halo
oh!
full junco
and these settings give a LOT of performance if you disable them
at least the ones I tried
raven halo
oh god yes
sorry
had a brainfart
haven't tried that yet
I'm scared to switch to 4.15 Preview 1
full junco
do it with a copy and see if stuff breaks, but it will probably work
HISMCs are broken though
but even master is quite stable, so 4.15P1 is fine too
mighty carbon
so turning all those check boxes off will yield more performance in mobile VR ?
full junco
@mighty carbon yeah, quite a lot I guess
full junco
I know that disabling the skylight and pointlight shadows probably got me something like 20% more performance I think
thats the non-mobile stuff
I'm not doing mobile stuff, so havent tested those
wicked oak
nice
im going to do performance checks too in 4.15
i like to be on the ultimate bleeding edge
and i kind of need it too
full junco
eevryone in VR needs it
raven halo
I need those awesome distance field indirect shadows so bad
do you guys know if there is any documentation about the permutations?
I want to read up more about it
or is it yet one more of those features with no documentation?
full junco
@raven halo no doc needed for "enable/disable"
and what you mean with indirect shadows?
raven halo
documentation that explains a bit better what it's doing or how it impacts performance
it's going to be kickass in VR
raven halo
it's dynamic o_O
it works for dynamic objects in a baked lighting environment
I would say it's quite a common case in VR
static environment & dynamic props you can move around
full junco
usually not much stuff is dynamic in baked lighting cases
full junco
ok, mine isn't
raven halo
I find it hard to believe that "baked lighting" is not a common case in VR
full junco
it is
raven halo
it's the cheapest lighting solution
dynamic objects stick out quite a lot in this case
which is not good
and these new shadows help solve the problem
full junco
ok
raven halo
you don't agree?
full junco
but I still don't find stuff too awesome if I can't use it 😄
yeah I agree for that case its great
raven halo
ok ok 😛
raven halo
I'm reading up on permutations, and all I can find is that it optimizes compile time of shaders as less branching is needed. But I can't find anything regarding gpu performance improvements. were you referring to compile times before?
full junco
but the regular distance field shadows are really awesome, I would love to be able to use those. especially since daniel recently made them twice as fast (its in master)
raven halo
oh sweet!
balmy creek
Does anyone know how to stop SteamVR from launching with every UE4 project? Been happening to me since 4.14. 😦
wicked oak
nope
it happens becouse it tries to load VR
have you tried removing ALL vr plugins?
full junco
@raven halo I was talking about gpu performance
raven halo
ok, I will try it out then
full junco
I tested it and it was way faster after disabling that stuff, if it isnt then maybe I didnt test correctly
raven halo
if I google "permutations shader" all I can find is people talking about compile times
kinda makes sense
it just outputs a different shader for each branch
full junco
but to me it kinda makes sense that a shader that needs support for skylights is slower than a shader that removes all skylight related stuff before compiling it
raven halo
I think having that checkbox "on" means that it will create a branch that has no stationary skylight and will use that version of the shader when no stationary skylight is used
turning it off means that you are turning off branching for it, and thus dropping support for stationary skylights.
you won't care because your porject doesn't have stationary skylight, but you will gain time when compiling shaders
mighty carbon
full junco
@raven halo it makes sense like that too
I didnt really care about what it does
I just tested and was happy about more performance 😄
maybe my pc just suddenly got faster and that gave me better performance
raven halo
I'll check it out and let you know, but it doesn't make much sense to me. At least the way I'm understanding it
full junco
it definitely doesnt hurt to disable the stuff that isnt needeed
raven halo
@mighty carbon I can't believe that doesn't cause motion sickness 😮
@full junco you are right, worst case scenario, GPU stays the same but my compile time is lower 😄
mighty carbon

Question little new , Am I able to create a new level using the VR Template and invlude my own buildings meshes etc. Then would I just have to place the correct nav bounds etc?
wise thunder
Correct. One thing to know though is that sometimes expanding upon the templates isn't as easy as you would think, based on architecture
But that's on the mechanics side. Making your own levels should be fine
still frost
What would be the better approach to implementing the VR components? Make them from scratch or am I missing a feature I dont know about?
I know unity is very simple with that vrtk thing but i honestly dont like unity
wise thunder
You could do a couple things... the setup Epic has right now for the pawn is pretty basic, and it wouldn't be hard to replicate. There's also a plugin called VRExpansion on the forums, and it introduces a couple classes that are setup to work well together. This plugin might run into the same issue though, since you don't set up all of the architecture, you might find the way it's setup to not be what you want fully
(for example, the GameMode tells the PlayerController to spawn a pawn? Maybe it has advantages but I've never seen something like that before, and it's not what I'm used to)
grim condor
use the supplied VR level., it comes pre set up with locomotion and pikup/place objetcs
wise thunder
I'm not saying the template is bad, I just see certain things that are against usual UE4 form in other templates that are really hard to grow a game off of
If you're just looking to make a level and go around it, using the template would be your best and easiest bet, yeah
still frost
what if i want to make my own everything building off the template is still wrong? or do you mean like building off the template level is wrong
wise thunder
IMO you'd have to do tweaking to the template to a level where it's not even worth it if you want to add a ton of mechanics
Plus, I think setting things up always allows you to see how things interact and work, and I'm not saying boilerplating everything is good, but it can be beneficial the first time
But at the same time, if you don't want to do a ton more, just using the template can be fine
still frost
I understand
sturdy coral
@balmy creek one way is to launch the editor with the -nohmd flag
4.14 also added a -hmd flag to choose which plugin you want: -hmd=oculus (or just hmd=oculus ?) on the commandline
balmy creek
@sturdy coral Thanks for the tip! Disabling the SteamVR plugin on a per-project basis also worked for me.

one thing to watch out for is if you have an oculus hmd plugged in
it hijacks your audio even on 2d projects
even with -nohmd and possibly without the plugin at all

there are so many related concepts that its hard to google it without knowing the terms

i'm assuming its not rigged is it?
if no then you can use mixamo autorig
and then import it into unreal like any other mixamo character
bunch of tutorials out there
paper hawk
mixamo is external software?
midnight tree
yep
currently still free to use
i believe
here
basically upload your character (make sure its in T pose)
auto rigger adds the skeleton
and weighs it fairly well
then look up some mixamo import tutorials on youtube
and import it
paper hawk
nice, your consultation is much appreciated!
midnight tree
no worries glad i could for once help out in this channel 😛
paper hawk
You certainly have
midnight tree
some things to look into as well
depending on what animations you want to use
if you want you can "retarget" the skeleton in engine
which basically means match 1 skeleton to another
so you could import the mixamo character
retarget it to the unreal mannequin
and then use the starter pack animations
OR you can stay with the mixamo skeleton and use mixamo animations
up to you
but the keyword is "retargeting" in case you start searching
paper hawk
any idea what this means?:
Can I use Mixamo royalty free or in commercial projects?
Yes. Mixamo is available for a limited duration as a technology preview and is available free, >without license or royalty fees, for unlimited use in both commercial and non-commercial projects.
what is a technology prieview?
Does that imply that after some duration, the assets will no longer be licensed?
midnight tree
alright basically
you are free to use anything currently rigged by mixamo
or created in fuse ( a character creation program)
you don't have to pay that company anything for this service
they are in the process of changing things and might go to a paid model soon
once that happens this will most likely change
so for now
you can download and rig as much as you need at no cost

@paper hawk just like @midnight tree said, you can download them now and get them for free. Even if they change the licensing / charge something for them in the future, you can still use the things you already got
and Mixamo has reputation of removing things without any warning so things could happen overnight unless Adobe now controls that kind of behaviour

Read that as "you don't need to be blind"
mighty carbon
I mean, why do you need VR to simulate blindness or to make a game for blind people ?!
Even if one wants to get a rid of old school controls and use HMD, Google Cardboard (via Daydream) will do the trick and would be accessible to everyone
full junco
@raven halo you saw what konflict wrote in the thread about bloom?
@wicked oak you were interested in it too
mighty carbon
@frosty prawn Do you still support this https://wiki.unrealengine.com/Portals ? Any chance to upgrade it for 4.14.x and 4.15.x ?
frosty prawn
Negative, I never actually uploaded the plugin because of IP dispute
but i can't for the life of me figure out how to kill the wiki page -.-
native cedar
so, still no multires in 4.14?
frosty prawn
I couldn't, basically I got into a bit of a battle over who owns the source code. IMO it's free for me to distribute, but in someone elses opinion it's their unique IP / a USP - so rather than burning bridges I just stalled it
full junco
ok
mighty carbon
so, if anyone makes portals for UE4 from scratch, it will be an IP dispute with that someone else? I don't see how it's even feasible :/
mighty carbon
right, but I was asking if @frosty prawn cares to make a new version, from scratch
native cedar
why is multires implemented in 4.14?
frosty prawn
Ah I see what you mean, I basically did remake it from scratch - but the source code is pretty much the same still, so it's debateable
native cedar
¬really hoping¬
frosty prawn
tbh though, I have no idea if VR portals ever actually worked for reals - cus i had no headset to test with haha
But the basic idea involved getting which eye you were currently trying to render from the Local Player View Settings, and offsetting the scene capture transform matrix.
full junco
@frosty prawn I dont know how you implemented it, but in VR the portal would need to show different images for left and right eye, which is more complex than in 2D
frosty prawn
You capture the scene twice, once for left eye and once for right. Left and right eye use different material instances with the two render targets
full junco
yeah, that should work
frosty prawn
Also means it ridiculously expensive haha
full junco
yeah, I would never use scene captures in VR
also don't understand why @mighty carbon is asking about it, since in mobile VR its an absolute no-go
frosty prawn
yeah it would die on mobile VR. There were some optimizations I made, such as only updating the render target if the scene capture view frustrum was in screen-space, and if the player had actually moved - so you saved some performance there when not looking at it
It also precached render targets so you don't create them dynamically
(i.e. at game startup or somesuch)
None of that stuff is too hard to do though
mighty carbon
so, mobile VR is absolutely a no-go with portals ?
frosty prawn
100% no-go
mighty carbon
😦 thanks
frosty prawn
hell it tanked a 970 to like 45 fps in a simple scene
frosty prawn
less compelx renderer in portal
mighty carbon
lol
full junco
ue4 scene captures also arent super optimized I think
theres a quite high static cost for them
frosty prawn
You could make it "relatively" performant by switching off rendering features - but it depends what you're going for
They're just as expensive as re-rendering the scene, there's not really much you can do to reduce that 😦
rendering the scene costs what it costs unfortunately
mighty carbon
it's just weird.. Prey was running blazing fast back in the days (so did Portal) and I am sure they did it the same way UE4 does it.
frosty prawn
They do it slightly differently I think - but Portal scenes are SUPER simplistic, and they don't have a lot of rendering features
mighty carbon
what do you mean by "rendering features" ?
frosty prawn
And of course it's much easier to make something fast if you're building it bespoke. With Unreal it's gotta work for all sorts of situations
Like Ambient Occlusion, HDR lighting etc
I mean portal probably has those basics, but I mean more in the general sense of what UE features in it's renderer
mighty carbon
well, none of that is turned on in mobile VR
frosty prawn
yeah but the Unreal mobile renderer is slow as fuck haha
frosty prawn
It definitely could be improved, but until epic goes through a full production pipeline for a mobile title we'll probably never see that happen
mighty carbon
wishes for a lean game engine designed for mobile VR
frosty prawn
tbh after doing a mobile title, I'll never touch mobile platform again haha
absolute ballache even without VR
never come so close to topping myself
full junco
vulkan will probably improve it though?
frosty prawn
Problem is Vulkan in UE will onyl ever be as good as UE's implementation / interface with it
full junco
yeah, but is it not good?
frosty prawn
I honestly never used it on Mobile, but that's cus when we shipped Vulkan was still experimental etc.
full junco
rolando seems to spend a lot of time with it
frosty prawn
Did try the Android AEP once... jesus that was awful
cobalt relic
Running VR resolutions at VR framerates on mobile is always going to be hard, to be fair.
full junco
vulkan is considered usable for SM4 now I think
and for mobile too of course
so only SM5 is still not there yet
cobalt relic
See how Switch games are 720p 30fps with a high-end mobile GPU 😦
mighty carbon
@frosty prawn with 5M units of Gear VR sold, and mobile VR != mobile, I don't see why would you not consider mobile VR to be a viable platform.
frosty prawn
It's just the saturation for regular mobile market for me
cobalt relic
This discussion has been had before 😃
frosty prawn
Haha yeah probably lot's of times. IMO though it's Saturation, as a small company you usually have very little if any real marketing / social media clout. You can sink thousands into marketing a mobile game with little to no return.
Even if the game is good, it gets buried SO quickly that the chances of success are more down to luck than whether the game is decent or not
Not saying our game was much good, because it really wasn't IMO - but even so
full junco
you didn't like your own game? 😛
full junco
not a good basis for success
cobalt relic
Gear VR is also being bundled, so people might have it by accident / curiosity rather than sheer interest
frosty prawn
still do.. but it's not a project we really 'chose' to do - it was a way to reuse a lot of existing work we had to make somethng profitable
full junco
and did it make it profitable?
frosty prawn
Did it fuck haha, but it made it not a total loss - we made some of the dev money back
Basically we we're in a position whereby we we're pretty confident that we could get investment for what we wanted to do, so it was a way to get money into the company so we could keep going.
Unfortunately the project took a LOT longer than planned
Steam version is much better though, actually happy with the work I've done on that
frosty prawn
Haha well in this case it was because half our staff left, and I was the poor sucker left behind who had to make the game
full junco
I wanted to release mine a long time ago and I'm still working on it...
frosty prawn
So getting stuff done took AGES
frosty prawn
^ ditto - for pet project that is
not constantly though, I admit
but sat command took about two years all said and done. Would have been a lot bloody shorter though if we just said "let's do a PC game" from the start, instead of "lets make a visitor attraction experience, now lets try and turn that into a mobile game, okay lets turn that in to a PC game"
I since learnt to take all advice with a big pinch of salt haha
full junco
ok
frosty prawn
anyway... back to work 😦
mighty carbon
There is no saturation in Oculus Store
mobile VR currently is the market to be on.. It's like the beginning of times.
Google Play - not so much
frosty prawn
tapping into tech early can definitely work out for some
For me though the production process for mobile was enough to put me off forever
mighty carbon
😃 I can relate to that, but I come from Quake modding, so it's something I prefer to next-gen
full junco
4.15 added new console commands for better weaking TAA, one of them is r.TemporalAACurrentFrameWeight and that really makes stuff less blurry
mighty carbon
(although it's nice to just throw it all together for PC and see it just work!)
frosty prawn
yeah developing for PC by comparison was a total breeze
on mobile every tenth of a millisecond was precious, I was doing some seriously roundabout stuff to get things playable
But also, the sheer variance between devices was the cherry on top for me
Random unheard of devices from china not working correctly etc...

Hello everyone. Does someone has experience with GearVR?
mighty carbon
@frosty prawn no need to worry about hardware making games for Gear VR - it's basically the same phone across generations.

I have absolutely no idea why the fps template packaged to my s7 does not allow/"support" the split screen setting for the gearvr.... Every time I start the app on the phone it immediately runs it as a normal 3d-fullscreen application

I think smell in VR is a very immersive thing.. I'd definitely use it if it was safe for health and odors wouldn't be extreme (motion sickness + foul smell is a "good" recipe)
or rather a thing that helps VR to be more immersive

Oh man.
I think I figured out what's causing some people to fail on the walking part of my system.
They're moving their feet up and down super high, and not moving their heads much.

raven halo
@full junco I've just seen the bloom optimization! I'm going to try it on GearVR soon. Today I've been working on a cheaper tonemapper. I've optimized it from 0.40ms on PC to just 0.04ms. Of course there are a lot of features missing, but it's way better than no tonemapper at all.
clever sky
I think... I'm going to do a video tutorial for the initial bit.
mighty carbon
@clever sky well, doesn't sound like a natural and working solution if you have to make a tutorial for it 😉
clever sky
It works well for most people. But some people take the walk on the spot bit too literally.
And don't understand that the system is looking for head motion caused by on the spot motion.
real needle
How can you tell your game to use the (damn) gear vr and the split screen? Nothing I do fixes it
mighty carbon
run it on Gear VR and see if it works?
real needle
It will not run in gear vr. If i start it, it immediately runs without me plugging it into the gear
When i plug it into the gear i can not start it because oculus home starts itself
It even tells me that my game would not support the split screen functionality, which i can not understand because i tripple checked everything before I packaged the game
What am I missing?
mighty carbon
then you aren't deploying it right
did you go over Epic's docs about setting up project for Gear VR ?
real needle
Yepp
mighty carbon
then I don't know - runs for me just fine
real needle
Did that the last two days
mighty carbon
as a matter of fact, I used FPS template, Epic's docs and the only issue I had was missing OSIG file. After I put it where it belonged, I ran my first Gear VR app ever.
first you need to set up your project for Android development, and then on top of that you need to set it up for Gear VR
if you follow the docs, you should have no issues
real needle
That's what i did. I used the fps template like everybody did because nearly every tutorial uses it
mighty carbon
and btw, split screen functionality has nothing to do with VR
real needle
I know that
But there is no checkbox in the editor for that so it confuses me what i should do to fix it
mighty carbon
sorry mate, no idea what's going on with your setup
what version of UE4 are you using ?
have you ever managed successfully deploy to Gear VR ?
mighty carbon
well, then, report it on AnswerHub
real needle
Will do, currently I'm driving home via bus, so it has to wait a bit
full junco
@raven halo interesting, so you edited the source of it to remove stuff that you didn't need?
raven halo
I pretty much ripped it all out and just added Uncharted 2's tonemapper
I get the feeling Epic overkills it too much on mobile
it's either all or nothing
full junco
unchartes 2s tonemapper? 🤔
raven halo
I still have to try it on the actual device
but it looks promising
but I will first try to get the bloom fixed
full junco
how did you just replace the whole tonemapper with something else?
is that so simple to do?
raven halo
not very simple... hold on
you have to find the function "FilmPostProcess" and replace it's content with whatever function you want
I'll share it once it's all cleaned up and working
I'm having some strange issues where the screen will turn black if I turn off bloom. I'm doing something wrong somewhere
full junco
hm ok, thanks
this is how my PP profiled currently looks like: http://puu.sh/tqMkK/302ef97a80.png
raven halo
no bloom?
full junco
TAA takes a lot of time, tonemapper is not much compared to that, but reducing 0.25 to less would definitely still help
I currently have no bloom, yeah
have not implemented what Konflict did yet
without those changes bloom is way too expensive
raven halo
this is mine
this for the PC project, not the GearVR one, obviously
then again, I'm running a 980Ti over here
full junco
histogram cou can disable unless you really need that
raven halo
that's the fancy eye adaptation, right?
full junco
yeah
raven halo
I kinda did some tests, liked it more than the basic one and sticked to it. I can afford it, for now.
where does most of your time go?
basepass?
full junco
yeah
HISMC LODs are currently broken though, so there are too many triangles there because stuff that should be higher LOD is LOD0 currently
and hm, ambient cubemap is relatively expensive it seems, 0.42 ms
raven halo
have you had success with HISMC in the past?
full junco
well what does "success" mean
raven halo
does it work, at all?
full junco
yeah, sure
full junco
yeah
I never thought about using anything else than HISMCs for foliage
its what they are meant for
there is nothing better
mighty carbon
HISMCs don't work well on Gear VR
full junco
well currently in master and 4.15 they dont work well anywhere because LODs are broken
mighty carbon
😦
If they make HISMCs work on mobile, fast and cull properly, that would be the day
full junco
why do they not work well on mobile?
mighty carbon
causing massive performance drop instead of boost
they don't get culled properly (culling should be done per instance and instead it's done per whole HISMCs component/actor)
dithered LOD transition adds to fps drop too
full junco
ok
mighty carbon
the idea behind batching/instancing is to reduce drawcalls. That's not the case with ISMC/HISMC in UE4, at least not on mobile
full junco
yeah on desktop it works great
@raven halo where is the real cost for the tonemapper happening?
raven halo
I haven't profiled each individual feature within the tonemapper
so I couldn't tell you
raven halo
FilmPostProcess, it's a function in the TonemapCommon.usf
full junco
the tonemapper calls the DrawPostProcessPass(...) function
every PP thing seems to call that function
ah, and that function then makes the shader file being executed
so I have to look into the usf and not the cpp files 😄
I somehow thought it would be more than just one usf file being called
I don't know much about GPU stuff
mighty carbon
@wicked oak why can't you use stationary lights in your DA dungeon ?
full junco
@raven halo can you somehow profile what happens inside a usf file?
wicked oak
i already talked in lounge
stationary use performance
a lot of it
they are dynamic lights
they just have baked shadows
but they are still dynamic
that means that due to the no light culling, it murders performance in a big-ish dungeon
it can be solved if i make it smarter
like deactivating ALL lights but the ones in the current room and the 2 next rooms
and be turning on lights as i arrive
so if i have rooms A-B-C
if im in A, then B has lights on, but C doesnt
once i move to B, C lights up
add doors to the mix, done
ima port VRMultigames to PSVR
to see how it goes
a full version of it for PSVR might fit quite well
mighty carbon
but Epic uses stationary lights in Robo Recall
also, what makes you think there is no light culling ?
we did the same thing in ToM - manually (via code) culling whatever needed to be culled outside of certain distance
wicked oak
the only light culling there is on the engine is culling by light size, and by frustrum
(it doesnt calculate lights behind you)
thre is no other type of culling
nobody said that you literally CANT use stationary lights in vR
its all about the performance
for what ive seen in robo recall, most spaces arent too big
so i doubt there are a lot of lights
you are fine adding a few lights
but if you are doing "fill lights" for example, you do those as fully static
full junco
and then there are people like me who can only use fully dynamic lights
granite jacinth
Oh snap
My Pixel XL may ship next week
Maybe I might try out some Daydream stuff
surreal nymph
Has anyone had an issue with the forward shading causing the blueprint editor to not have any light? (4.14.3, and this happens on clean projects too)
mighty carbon
@wicked oak it's all about compromises. In ToM we had to accept the limitations and that's all we had - only a handful of lights, even less lights casting shadows.
@granite jacinth Daydream HMD is $50 now (on sale until next month or something like that)
@wicked oak real-time random dungeons is no better than off-line generated random dungeons.
granite jacinth
@mighty carbon nice, thanks for the headsup, now to choose the right color
mighty carbon
actually people say that one should wait for Xiaomi's Daydream headset. It looks like Gear VR (adjustable focus, potentially no light leaks)

Just joined this channel recently. Is it possible to export UE4 games to display in Google Cardboard?
I'm a civil engineering major and only used ue4 as a hobby. Just started, so Idk much.
glossy agate
@south blade yes you can for android. As far I know it has no iOS support though. I have tried to get it to work, but it won't even build for me.
pearl tangle
@mighty carbon I think thats a step backwards. It's restricted to the 1 phone so it's more like the gear vr compared with how daydream should work across lots of devices
also @mighty carbon you saw the Samsung news right? Told you he wouldn't get arrested hah
mighty carbon
Nah, haven't been following it. I guess it's a good thing :)
Now just need for Zeni vs Ocu to settle down so things would go back to normal
pearl tangle
well pretty much he had a warrant for his arrest, then the government went "nah it's fine just leave him alone"
pearl tangle
hah well considering samsung makes up around 15% of South Korea's total GDP they don't really want to damage them too much
its pretty insane just how huge Samsung actually is. like people think mining is the biggest thing in australia and that only makes up like 2-3% of the GDP. but 15% in a single company, and like 25% of all their exports for an established country is ridiculous

fellow VR devs
I am about to embark for a mighty quest: capturing a 360 video in UE4
I seek counsel
pearl tangle
use the simple stereo exporter plugin. 100x easier than the inbuilt stereo plugin by kite and lightning
simple panoramic exporter sorry @native cedar
https://www.unrealengine.com/marketplace/simple-panoramic-exporter made by @barren rose works bloody great
native cedar
yeah I am experimenting with the kite and lightning thing
does it capture fabulous 4k too?
pearl tangle
i have done up to 16k capture with it
native cedar
I'll be needing to make a long video with animations, camera movement and stuff just like ninjatheory's
pearl tangle
both those are captured with his plugin
yeah you just do all that with sequencer. just move the camera around with it
native cedar
wow you put a video in a 360 video
how did you even get a movie streamed to a texture
pearl tangle
create a media texture
native cedar
by the way thank, I'll experiment with kite and lightning's for now as allar's requires a source build, but I'll get there
yeah nvm, now I remember
pearl tangle
but for capture with the correct timing when rendering you need to do it as a flipbook at the moment due to sequencer and the media texture not being able to sync properly still
native cedar
the problem was in unity
pearl tangle
allars doesn't require source build at all
it's just a plugin you can drop straight in
pearl tangle
just grab it off the marketplace, add the plugin to the engine, drag and drop in the camera and press play. hell of a lot easier than the stereo exporter
and 10x faster as well. the 4k captures took us about 3-4 seconds per frame in that first project i linked. compared to 40 seconds with the stereo renderer
native cedar
yeah, allar makes good shit. Asking my boss to authorize the purchase right meow :3
pearl tangle
definitely worth it. will save you a hell of a lot of time
native cedar
yup
pearl tangle
its well worth the cost and the lack of stereo doesn't matter too much really
wicked oak
for my screenshots in DWVR and VRMultigames i made a "cinematic"
native cedar
I thank you for your time. May I be able to repay you with advise on flex in VR, or... anything that I know
wicked oak
to pose everything, and set the FX to where i wanted
then i made the cinematic call the console command for a hiighres screenshot to see it
so when iwant a picture, i press Play, and the cinematic runs for half a second then captures
this is so i can control the particle effects proplerly
pearl tangle
ah yeah particles are an interesting 1 to "pose"
native cedar
aaaaaand it turns out we need stereo capture
barren rose
Fuck everything about stereo capture
Kite and Lighting's solution is best but god help you
Reason I made the simple panoramic exporter is because they went full stereo capture but a lot of people don't need stereo
And math for mono capture is like, super easy
Compared to stereo
With stereo you need to take a shit ton of images per image
And splice them together in crazy math ways
Good output is something like 30 different captures vertically for each 1.5 degrees horizontally
or some shit like that
Even with going with one vertical capture every 1.5 degrees horizontally still takes a ton of time
native cedar
There is no choice. This is what the customer wants. I will do as I am bid, defeat my inner demons to escape the bigger fangs. Blood for the code god. My body is ready.
https://media.giphy.com/media/O3dVvaVsON5U4/giphy.gif
we do have great hardware but I have seen it takes an awful lot of time to capture a single frame
and for how you say it it looks like doing mega-low res until production quality is needed does not help either
barren rose
it helps, but its only a part of your bottleneck
Literally everything about stereo capture is slow
native cedar
I'm assuming there is no way to get a stereo equivalent from one or multiple panoramic captures right?
barren rose
No
You'll get close, but there will be a particular type of artifact you and your clients will reject
Basically, when you do that, at some angles of your video, the eyes will be swapped
And you'll see a weird form of ghosting
And/or get a headache
Its basically simulated cross eye double vision
Do you have an easy way to play top/bottom stereo 360 video?
if so, 4k mp4 http://michaelallar.com/NYCStereoscopic4k.mp4
That will show you what happens if you try to do what you asked
(I too had a client that required stereo capture, experimented with things)
native cedar
it's consumer-oriented. A QR code to be scanned and a cardboard to be used
I'll show this to my foremen and see if we can do mono only
but I don't think
I'll experiment with fixedtimestep and stereo capture and god help me and blood for the code god etcetera etcetera
pearl tangle
hah yeah i did a test with your plugin @barren rose of just placing 2 cameras 64mm away from each other
pearl tangle
yeah doesn't work so great. just do stereo in after effects afterwards
pearl tangle
hah yeah but still much better off just exporting the single mono camera into after effects and then just running the automatic "stereo" generator thing on there and giving it some offset. Then Viola, you have some shithouse stereo done
barren rose
Aye, I've known people to do that with SPE and turn around with some good money using fake AE stereo
Fake auto stereo from 2d looks so much like fake auto stereo from 2d though
pearl tangle
yep but 90% of the people that you/ he are most likely showing this thing to wont notice the difference. You get a bit of depth out of it for the VR and that's it, gives you enough of the illusion to take advantage of the saved time for rendering and setup that your plugin gives
i just started doing mono stuff for all my clients and nobody noticed at all, they still thought the stuff looked amazing. didn't even bother trying to make it stereo
feel free to use those vids from my youtube as reference of your renderer @barren rose
we did a bunch of stuff at 8k 60fps with it, but then we were hitting like 900gb for 30 seconds of footage so backed down to 4k 30fps for the 1s without a lot of movement
barren rose
Aye, SPE has no cap aside from ram
Used it for client work which was technically facebook themselves
Wanted 32k
pearl tangle
the GPU memory was what is slowing us down
pearl tangle
gotta fork out for a titan if a big 1 comes in
barren rose
Literally the only use for a titan
pearl tangle
yeah. they are stupidly expensive over here in singapore though so dunno if I can be bothered. Would be handy if there was a way to split the load across GPU's and we can just throw 1 render machine with 4 gpus in it
tawdry dragon
Anyone here with some experience using VR and networking in UE?
pearl tangle
I assume plenty of people. throw your problem up
tawdry dragon
Okay...
so I have a 2 pc setup. 1 pc is running a spectator client(no HMD) and the other one is running an HMD. What I am trying to get to work is having the VR clients trigger presses getting replicated to the server. So I have set up a faily straight forward system that works like charm... until I turn on the HMD in the level
Meaning: Without my Oculus/Vive and HMD on, the client/server replicates everything. As soon as the HMD is turned on, replication stops working(RPCS never get fired)
WIthout HMD on: all 3 event fires as you would expect
With HMD: Only Client events fire, it never fires the RPCS
native cedar
haven't done networked VR yet, would love to try. I am reading there is some bug with motioncontrollercomponentreplication perhaps?
(to continue the stereo capture topic) for now I am sitting with kite and lightning's solution, the capture time for 10 frames on a monster pc (3960x, 1080) was almost 7 minutes... Now I am leaving for lunch with UE capturing a 150 frames footage, will see how long it takes. I will look for the best settings and share any useful result.
tawdry dragon
@native cedar yeah I know about that one. I get around that referencing the motioncontroller locally and save the transforms to variables that are RepNotify which then set the controller meshes correctly on the server
wicked oak
why would you need repnotify?
just replicate them and set them on tick
bonus, try to interpolate
its what im doing and its fine
tawdry dragon
interesting question... Will have to look at that later. I just need to figure out my replication problem/bug 😦
@wicked oak you have any clue what might cause this?
wicked oak
the ownership system
or that your motion controller actorisnt getting replicated
check your log
it gives you warnings
if you have that
if a client isnt the owner of that actor, then the RPC is dropped
thats so you cant access the pawn of other guy and tell it to jump
tawdry dragon
but MotionController (R) Trigger isnt part of the actor right? All this blueprint code resides in the PlayerController
wicked oak
player controllers arent replicated to other clients
they are server and owning client
they are the easy bridge beetween a client and a server, for rpcs
tawdry dragon
true, but this works as soon the HMD is turned off. No changes to code or anything
wicked oak
not sure
tawdry dragon
that is what is bothering me. If I disable my VR everything works as you would expect
as soon as I enter a VR session, it stops working
pearl tangle
@native cedar there is a very good post on the Epic blog by ninja theory that goes through a lot of the stuff they did. There is also a free plugin somebody made to give a menu system to do all the config stuff that comes in handy as well

You guys talking about Stereolayer in here?
Need tips. I'm trying to do render target stuff to stereo layer.
Got it working and updating dynamically.
But here's the kick to the nuts: It stops working on level load!
Need it for a good FOV restriction implementation D:
Anyone know what might be going on/more experienced with the stereo layer issue?

Thanks for the tips, I'll make more research. The first objective is to setup tonight's capture properly
barren rose
@clever sky No one is talking about stereo layer
But
Please document and blog all things you do stereolayer
:p
pearl tangle
hah agreed. this is all just talking about stereo 360 capture
wicked oak
ive been able to use the stereo layer
but ive not been able to render UMG to it
becouse it doesnt have alpha, the texture ends up opaque

@wicked oak what have you been doing to make it persist past level load?
And how are you using it? Is it a component in your character pawn?

trying to get the capture time down for that kite and lightning thing... Whatever I do it won't go below 40s per frame, I'm dumbing evertything down
NVM
just had to reduce the stepcapturewidth ^^
native cedar
so now I have all my frames nice and sharp and I'm trying to encode them into a stereoscopic video. I'm not doing too well

It seem to work with streaming levels. Didnt notice any misfunctioning yet between switches in levels
Try make a super simple poc of it. One with normal level switching and one with streaming
See if u can reproduce

@wicked oak regarding this:
"why would you need repnotify?
just replicate them and set them on tick
bonus, try to interpolate
its what im doing and its fine"
Im not sure what variables you are setting on tick, controller transforms or?

Uhm.. is there anyway to use Motioncontrollers without having to use HMD and Stereo on? im using a motioncontroller to controll a camera
it doesnt look like it's possible to track the Motioncontrollers without having a camera attached and enable HMD + Stereo on
what im doing right now is just attaching the camera to the motioncontroller.. but thatmeans that i get a portrait letterbox output aswell as the movement of the headset to the camera.

what would be the best way to simulate a cardboard on VIve?
if I move my head across the room I want nothing to happen
only track head rotation
full downgrade

do you have Android phone? Just get cardboard and work with Google VR 😉

I need dynamic preview of sequencer
very fast stuff
hit play and test the sequence

@native cedar couldnt you just set the location to [0,0,0] on the camera pr. tick?
or whatever coordinate you want it to be locked to
native cedar
tried that, doth not work
I think I'll have to move the default scene root to the desired location minus the current camera offset
wicked oak
i have 2 components
the Motioncontroller components
and the replicated components
now, in my improved version
i actually just have motion controllers
to avoid shanenigans, i only send the transforms to the server if im the owning client
and everyone else has "player ID" as -1
so it doesnt grab the hands

The Daydream is on sale for $50 for anyone interested
I wish it supported iOS, I'd pick one up.
mighty carbon
I wish my S6 had Android 7.1.1 already so I could at least see what it takes to build for Daydream (and I'd buy this viewer while it's on sale)
the problem with Daydream is that UE4 is a way behind on SDk updates and there is no spatialized sound for Daydream (and not even through FMOD).

I'm, eh, failing to implement teleporting in blueprints. All I get is teleporting controllers.

What am I doing wrong?

profileGPU crashes on gearVR right?

Ah, got it working now. Needed the player pawn instead of a reference to it in the level.

@wicked oak thats interesting. Right now Im doing this https://forums.unrealengine.com/showthread.php?107140-Motion-controllers-and-networking&p=551926&viewfull=1#post551926 and I have the following problem: When I play locally, it works perfect! When I connect to my multi player session, my clients controllers get extremely offset but my servers instance of said controllers are perfect!

@raven halo no idea, but how is it going with bloom on Gear VR ?
raven halo
haven't looked into it yet. I'm currently trying to use parallax corrected cubemaps in my own shader
got those working, and hit a wall with controlling mip maps through texture to emulate roughness. Works on ES 3.1
the good news is I don't see a difference in performance between 2.0 and 3.1
(with my own shaders that is)
tawdry dragon
@wicked oak if you by any chance could send me a picture of your setup, that would be very helpfull 😃
raven halo
jeez.... profiling GPU on gearVR is impossible
stat gpu doesn't work
profileGPU doesn't work
stat startfile works, but the GPU group is missing
😩
mighty carbon
@raven halo I don't see how it's possible. Even Oculus devs themselves confirmed ES3.1 doesn't work well at all in UE4 on Gear VR.
Maybe Epic can hire you to overhaul renderer for Gear VR 😉
raven halo
like I said, I'm not using the default shaders, so that might be why

the HISMC LOD bug got fixed, so in 4.15P2 it will be fixed
mighty carbon
what's the benefit in using ES3.1 vs ES2 ?
full junco
more rendering features I guess
raven halo
yeah
in my case, specifically, it allows me to sample cubemaps and choose between mip maps based on a texture
it's also technically possible with ES 2.0 through an extension, but Unreal doesn't implement it
not sure why
I mean, gearvr in general isn't getting much love
that's the impression I'm getting
mighty carbon
welcome to the club
worth noting that UE4 got multi-view (not working correctly) and monoscopic rendering (haven't tried it yet) for Gear VR
but if shaders is the bottleneck and they don't fix it, it's pretty sad :/
raven halo
I'm not sure how much monoscopic rendering would help the GPU, yeah.
I think I'm settling for no bloom at all
also no MobileHDR
however, I'm doing the tonemapper per-material
that's how post process used to work on mobile games back in the day
I'm also capturing a cubemap with the scene render cube, converting it to a static texture
and sampling it in the shader
on top of that I'm parallax correcting it, so it's a big improvement over "regular" cubemaps in Unreal mobile, where they just "float"
and I'm using ES 3.1
working at 59.90 fps (it can't reach 60 fps due to vsync, yada yada)
the only reason I'm using ES 3.1 is to be able to add "roughness" to the cubemap

"One of the main issues with monoscopic rendering is that its goal to minimize pixel shader work can be compromised by the lack of occlusion between the stereo and mono layers. Since we’re not rendering the objects close to the camera in the monoscopic view, pixels that will not be visible after composition are still shaded in the monoscopic buffer as nothing is occluding them there. To avoid this, we chose to render the stereo views first, then read their depth buffers and compute their intersection."
ok that's what I was worried about, that's smart though!
"However, scenes that have lots of expensive close-up content can see a performance decrease while using monoscopic rendering due to the fixed costs of rendering a third view and the monoscopic passes of depth masking and composition."
makes sense, sucks though
raven halo
why are they not adding any of these to PC?

i dont know
