#

It's a simple game with humor, not a ton of replayability but people I've shown this to as their first game like it

mighty carbon Mar 8, 2017, 7:34 PM

#

just weird that's all

wicked oak Mar 8, 2017, 7:34 PM

#

for the VR devs, i finally found a way to do 3d widgets

#

as stereo layers

mighty carbon Mar 8, 2017, 7:35 PM

#

I thought you did it before

wicked oak Mar 8, 2017, 7:35 PM

#

it wasnt working becouse last time, i had mipmaps enabled on the render target, that somehow didnt let the render target have Alpha

#

now it does work

mighty carbon Mar 8, 2017, 7:35 PM

#

ah, I see

wicked oak Mar 8, 2017, 7:36 PM

#

not sure about perf tho, im rendering the texture and all of that. But its promising

mighty carbon Mar 8, 2017, 7:36 PM

#

I forgot, what's the benefit of using UMG in a Stereo Layer vs as-is ?

wicked oak Mar 8, 2017, 7:36 PM

#

stereo layers use textures

#

umg is a umg, it can do fancy stuff

#

the idea is rendering umg into a texture, thne use that texture for the stereo layer

#

but of course it needs some stuff

mighty carbon Mar 8, 2017, 7:37 PM

#

what's the point though ?

wicked oak Mar 8, 2017, 7:37 PM

#

with this you get HUD that is inmune to fps drops, and to TAA, and to postprocess

mighty carbon Mar 8, 2017, 7:37 PM

#

I see

wicked oak Mar 8, 2017, 7:38 PM

#

gonna check how it goes for PS4

#

its the most important

#

at 90 fps constant, the stereo layers are cool but they arent that much important for a hud

#

at 60 fps reprojected to 120

#

holy shit they are

#

specially with the TAA

#

robo recall uses stereo layers for the loading screen

#

might make a wiki and forum thread if i feel like it

#

its a very important thing for VR devs

mighty carbon Mar 8, 2017, 7:40 PM

#

but is their loading screen a UMG ?

wicked oak Mar 8, 2017, 7:40 PM

#

no, its textures

mighty carbon Mar 8, 2017, 7:40 PM

#

well, I use Stereo Layer for my loading screen too 😃

#

(since it's a simple texture with text)

wicked oak Mar 8, 2017, 7:41 PM

#

how do you use it for the loading screen?

mighty carbon Mar 8, 2017, 7:44 PM

#

just have it in the black room, depth test disabled and world locked

#

bam! - loading screen 😛

#

(and meanwhile main level streams in the background)

wicked oak Mar 8, 2017, 7:53 PM

#

robo recall is sneakier

#

they add them, then do a Open Level, and then remove them

#

and they add them in a way that its not directly an actor, so they are still there even while switching the level

#

im gonna check how to do that, becouse its baller as fuck

mighty carbon Mar 8, 2017, 7:56 PM

#

well, if you put it into permanent level, then it will always be there

wicked oak Mar 8, 2017, 7:56 PM

#

i think i can try to do it like robo recall

mighty carbon Mar 8, 2017, 7:56 PM

#

even when you switch levels

wicked oak Mar 8, 2017, 7:56 PM

#

do a "box" of black stereo layers to block everything, and add a Loading one

#

and do that "directly on the hmd" without actors

#

to bypass that level load stuff

#

that way i wouldnt need to do a stream level at alll

mighty carbon Mar 8, 2017, 7:57 PM

#

it's a component, so I don't see how you can do it without having a BP actor

wicked oak Mar 8, 2017, 7:57 PM

#

you can do it directly to the HMD

#

wich is what im going to try

mighty carbon Mar 8, 2017, 7:57 PM

#

how?

#

you can have it player's component

wicked oak Mar 8, 2017, 7:57 PM

#

if (LayerId)
{
StereoLayers->SetLayerDesc(LayerId, LayerDsec);
}
else
{
LayerId = StereoLayers->CreateLayer(LayerDsec);
}

#

the Stereo Layer Component does it

#

so basically just copy the code from that

mighty carbon Mar 8, 2017, 7:57 PM

#

well, I don't do C++, so..

wicked oak Mar 8, 2017, 7:58 PM

#

i think robo recall does it anyway

#

without the c++ part

#

you could try to see how its done exactly

mighty carbon Mar 8, 2017, 7:58 PM

#

well, again, if it's a component, it has to exist somewhere

wicked oak Mar 8, 2017, 7:59 PM

#

the component just calls the HMD code

#

the thing would be to just call it without that component

#

alternatively

mighty carbon Mar 8, 2017, 7:59 PM

#

I'd like to see how you'd do that in BP

wicked oak Mar 8, 2017, 7:59 PM

#

create your own stereo layer ocmponent

#

that doesnt get destroyed

#

until you tell it to

#

well, it gets destroyed

#

but it doesnt "remove" the layers

mighty carbon Mar 8, 2017, 8:00 PM

#

afaik you can't add components to the scene

#

you have to have it in an actor, player or whatever actor

#

if i have a long usb cable, and wanna connect an additional vive controller, how come SteamVR keeps saying i can only have two controllers paired?

#

ok think i got them all paired

#

📎 unknown.png

#

one of them is doing the fading up and down though

#

so, how do i actually get tracking data from it?

#

Tried adding a 3rd MotionController Component

#

📎 unknown.png

#

📎 unknown.png

#

Tried with other settings for Hand, Pad was just the next in the row

#

but none of them seem to give me movement of my Cube

#

aha, Get Tracked Device Position and Orientation gives me data

#

📎 unknown.png

#

so just need to figure out if there's a way to tell the MotionController Component which Device it belongs to

eternal inlet Mar 8, 2017, 10:37 PM

#

or i guess Get Tracked Device Position and Orientation is just the way to go, and ignore the MotionController Component for any additional devices

pearl tangle Mar 8, 2017, 11:58 PM

#

yeah you can do that

#

you need to make an engine modification. they have some extra stuff in there now which relates to the steam trackers. I posted up some code on here before from Epic that worked

#

and its actually device id 5

#

id 3 and 4 are the lighthouses

digital marlin Mar 9, 2017, 12:54 AM

#

Does that mean you could technically use three MCs?

pearl tangle Mar 9, 2017, 1:02 AM

#

you can use 14 actually

#

maximum tracked devices is 16 minus the 2 base stations

#

and you can use them wirelessly too if you use the steam controller wireless 1 to pair it instead of a usb cable

digital marlin Mar 9, 2017, 1:05 AM

#

So, hypothetically, I could attach one on my junk

#

hypothetically..

mighty carbon Mar 9, 2017, 1:06 AM

#

for science

pearl tangle Mar 9, 2017, 1:06 AM

#

well thats why the steam trackers are being made small 😉

#

it will be part of the steam vr setup for an IK rig with 3 trackers and 2 controllers. 1 of those trackers is on your pelvis so that helps

yeah i only managed mine by being on the phone with the head of vive in europe but then on the web I couldn't set the shipping location to be singapore and didn't want to delay it so just got them sent to my other office first

@winged shale yo. So how'd your Daydream stuff go?

winged shale Mar 9, 2017, 3:35 AM

#

I had a lot of fun, but ended up almost bricking my Pixel so I stopped and got scared off. Unity is certainly better suited to doing Daydream, but I still love Unreal for desktop, especially now since the obvious performance upgrades. The last few months I've been in charge of undergraduate researchers which has been fulfilling but time-consuming initially. I'm hosting a lecture on learning CPP so they'll be all on the same page, and we can get some research done. That's wrapping up now, and they're a bit more self-directed. I've been spending weekends working on Iron Rain, a feature here, a feature there, that kind of thing.

Because goddamn, setup and tear down of Vive is not trivial!

winged shale Mar 9, 2017, 3:39 AM

#

The main textbook is learncpp.com, just doing the chapters, and the comprehensive quizes at the ends of each chapter. It's working well, and I give lectures each week to supplement the material. I wish I had throught to tape them. I just gave a good interactive one on pointers and class organization, where we semi-collaboratively made a 'bicycle class' that you could 'ride,' which computed some nontrivial aspects of a bicycle, such as gear ratio, pedaling RPM, wheel size, etc. for the purpose of bringing together some software architecture stuff

clever sky Mar 9, 2017, 3:41 AM

#

Ah yeah.

#

That sounds a lot like the kinda stuff I need to wrap my head around...

#

architecture for reusability.

winged shale Mar 9, 2017, 3:42 AM

#

and yeah it's wonderful, I love how I can plug-n-play on the laptop and everything just works, I repasted mine with coollaboratory's liquid metal thermal compound, and aggressively undervolted the CPU to get absolutely no thermal throttling when in VR

#

I love that you can use just one base station for the Vive in A mode for tracking

clever sky Mar 9, 2017, 3:42 AM

I paid roughly the same for mine... but it was clearance stock with 1k off retail.

winged shale Mar 9, 2017, 3:46 AM

#

wowowowowow

clever sky Mar 9, 2017, 3:47 AM

#

They updated the CPU from skylake to kabylake... so they reissued the same laptop pretty much.

#

And retailers stopped stocking the older model.

#

AFAIK, there's not a hugely appreciable difference between the two chipsets.

winged shale Mar 9, 2017, 3:47 AM

#

there was a G702 at Best Buy with a 1060 in it for 1000 returned new condition, so tempting

#

yeah, I can undervolt it much better than skylake imo though

clever sky Mar 9, 2017, 3:48 AM

Fair enough 😃

#

In retrospect, I would've been much better off with the laptop you linked.

You don't appreciate how fat this thing is

How do I "Preview in VR" with an Oculus Rift?

digital marlin Mar 9, 2017, 6:30 AM

#

Have you enabled VR via plugins

pearl tangle Mar 9, 2017, 6:31 AM

#

yep it's pretty straightforward with any version of unreal after 4.7 I think

south blade Mar 9, 2017, 6:33 AM

#

Plugins?

#

Let me look this up

#

It's nothing to do with Oculus not allowing games that isnt in their store?

pearl tangle Mar 9, 2017, 6:34 AM

#

you just click on plugins and then under VR you should have the Oculus Rift plugin enabled

#

huh

#

you are trying to run it in the editor right?

south blade Mar 9, 2017, 6:34 AM

#

I'll try it tomorrow when I'm at school with the oculus.

#

Yeah, in the editor for now.

#

Then eventually I want to put it in an executable

pearl tangle Mar 9, 2017, 6:35 AM

#

and the preview in vr button is greyed out for you when you have the rift plugged in and all the software running and you are on a version of unreal >4.7?

south blade Mar 9, 2017, 6:35 AM

#

Yup. It's greyed out. Running 4.15

#

Keep in mind, I have this setup at school and im at home now.

#

I'll try out that plugin tomorrow and get back to you

eternal inlet Mar 9, 2017, 6:42 AM

#

@pearl tangle so 3rd controller is always id5?

pearl tangle Mar 9, 2017, 6:42 AM

#

yep should be

#

@south blade if you start a VR template project it should be enabled by defgault

south blade Mar 9, 2017, 6:43 AM

#

hm. I did start a vr template project

#

ill double check if the plugin is on tomorrow

#

if not, do you think it has something to do with the rift

#

because i know the vive is more open to any game

eternal inlet Mar 9, 2017, 6:44 AM

#

@pearl tangle And u said i can use them wireless if i use steam controller wireless.. how do i do that?

south blade Mar 9, 2017, 6:44 AM

#

you just have to turn on steam vr for vive

eternal inlet Mar 9, 2017, 6:45 AM

#

Can u post a screenshot of where that is?

digital marlin Mar 9, 2017, 6:46 AM

#

dumb Q but is the VR device on?

south blade Mar 9, 2017, 6:46 AM

no sorry jonas. i was talking to zoltan

Aah lol

digital marlin Mar 9, 2017, 6:47 AM

#

lol was that it?

south blade Mar 9, 2017, 6:47 AM

#

Yeah, it was on. Because I was using the oculus app to configure it and run that mini-game that oculus gives you. Dream-something.

#

Even though, the "Preview in VR" option is greyed out. I tried choosing "Preview in external window". After choosing that, the oculus app would always open along side the external window of my level.

#

In the rift, I would see the main menu to the oculus app.

pearl tangle Mar 9, 2017, 6:51 AM

#

the rift works fine inside unreal, its probably the plugin

#

for @eternal inlet You pair it with the wireless receiver for the steam controller

eternal inlet Mar 9, 2017, 6:54 AM

#

Ok im clearly missing something

#

When i tried to pair the 3rd controller, it said that i could only have 2 paired

#

Is that because they're communicating with the hmd?

#

The wireless steamcontroller u say.. is that a dongle of a kind?

#

Sorry.. im super confused

south blade Mar 9, 2017, 6:57 AM

#

thanks @pearl tangle ill test it out and get back to ya

eternal inlet Mar 9, 2017, 6:58 AM

#

Never touched the steamvr for other things that getting the standard vive running

#

Also u mentioned that i need to make engine modifications.. does this still hold for 4.15?

clever sky Mar 9, 2017, 7:34 AM

#

@eternal inlet Experimenting with multi-controller tracking now?

pearl tangle Mar 9, 2017, 9:16 AM

#

yeah the HMD can only handle 2 controllers. The third will connect over USB cable fine. if you want wireless you need to flash different firmware and use the Steam Controller. the xbox style gamepad. You take the wireless receiver for that and connect the vive wand to it instead of the controller @eternal inlet

#

and yes the engine doesn't have the default stuff in there for multiple controllers, need to make tweaks for the trackers and the like

clever sky Mar 9, 2017, 9:18 AM

#

Sounds like a mega hassle

eternal inlet Mar 9, 2017, 9:18 AM

#

@clever sky yes 😃 got tracking to work with a 3rd controller, though only via the GetTrackedDevicePositionAndOrientation node

#

And using a usb extender

#

@pearl tangle steamcontroller = software or a box?

pearl tangle Mar 9, 2017, 9:20 AM

#

look up steam controller on google and you will see

eternal inlet Mar 9, 2017, 9:20 AM

#

Good idea hehe

#

And good answer 😜

pearl tangle Mar 9, 2017, 9:21 AM

#

eternal inlet Mar 9, 2017, 9:22 AM

#

Nah

#

Zoltan>google 😉

pearl tangle Mar 9, 2017, 9:23 AM

#

its where most of my responses come from

eternal inlet Mar 9, 2017, 9:24 AM

#

So as i read it from google, the steam controller is a gadget to play games with that connect wirelessly via a dongle

pearl tangle Mar 9, 2017, 9:24 AM

#

👍

eternal inlet Mar 9, 2017, 9:25 AM

#

And u say i can connect multiple vivecontrollers to one steamcontroller dongle? Or i need 3 steamcontroller dongles?

#

For 3 vive controllers

pearl tangle Mar 9, 2017, 9:29 AM

#

1 dongle per controller

@wicked oak do you know if the forward renderer works with Gear VR and is there any performance gains to be had?

wicked oak Mar 9, 2017, 9:47 AM

#

its the default @tawdry dragon

#

mobile doesnt use the deferred renderer at all, it never did

tawdry dragon Mar 9, 2017, 9:50 AM

#

hmm. Okay - so nothing to gain there

#

At the moment I am getting 20 minutes on a S6 for such a simple app.. I dont get it. Running oculus branch of 4.13, setting CPUandGPULevels to 3,2

#

The biggest overhead is that when the menu is shown, I show ~15 individual widgets with an unique texture... But the menu is only visible for a few seconds at a time

#

I am building Oculus branch 4.15, hopefully upgrading gives me a bit of performance in it self

pearl tangle Mar 9, 2017, 9:53 AM

#

20 minutes as in battery life?

tawdry dragon Mar 9, 2017, 9:53 AM

#

no, overheating

#

only uses around 10-12% battery

#

One thing I could do is texture atlas our thumbnails, so it only ever loads one texture

#

in hindsight, we probably should have done this app in Unity. So much easier to find danish freelancers to fix unity than UE :p

sharp swan Mar 9, 2017, 10:02 AM

#

I do freelance work if you feed me danish pastries if that counts?

tawdry dragon Mar 9, 2017, 10:12 AM

dusky moon Mar 9, 2017, 10:26 AM

#

guys I'm trying to make a neat VR laser pointer for my UMG Interactions ... any suggestion ?! I actually liked Robo Recall's but can't see how they implemented it

eternal inlet Mar 9, 2017, 10:29 AM

#

@pearl tangle ok, that makes perfectly good sense. So in essense, its working the same way as the Pucks do. Think i'll just stick with the Pucks once they're out.

#

btw i didn't have need to mod any engine code to get tracking data out of it, so unsure what you meant by that?

pearl tangle Mar 9, 2017, 10:40 AM

#

well the pucks will work off a single receiver, you wont need 16 receivers for 16 pucks

sharp swan Mar 9, 2017, 10:40 AM

#

@dusky moon there is many ways to skin that cat. it all comes down to the Line Trace functionality. Getting your starting location vector and the vector of the where the trace hits or ends. Then you can use a material to draw the line between, or a simple DrawDebugLine (not for production) or use a mesh to create a line. Depends on your needs

pearl tangle Mar 9, 2017, 10:40 AM

#

they are adding stuff in to identify the type between the different trackable actors

#

dont think it's made it's way into the main branch yet but shouldn't matter if you aren't caring about if its a puck or controller

dusky moon Mar 9, 2017, 10:48 AM

#

@sharp swan Thanks good points, I think I'll try to skin it with spline meshes .

sharp swan Mar 9, 2017, 10:51 AM

#

yeah thats one way but unecessary. You do the trace and you already have the start, end points. Then all you need is to put the mesh in but if you find it easier that way then all i can say is go for it.

vagrant mantle Mar 9, 2017, 11:04 AM

#

Y the custom depth pass for static mesh does not work in GearVR

clever sky Mar 9, 2017, 11:44 AM

#

@dusky moon Robo Recall just uses a cylinder mesh that scales the Z axis according to the length of the line trace.

#

Apply appropriate material add sphere and voila. Laser pointer.

sharp swan Mar 9, 2017, 11:48 AM

#

thats how I did it with my 3d radar for height indicator lines

#

I tried with debug lines first but then realised its not production flagged. Then I tried billboards with materials which was ok but I went with the base engine cylinder mesh and scaled it as it gave better options for animated materials

dusky moon Mar 9, 2017, 11:50 AM

#

@clever sky Yes I'll go for that. just wondering to set the Z scale of the Beam Mesh ... should I get the length of my trace line and then calculate the scale ... right ?

#

I suck at vectors 😄

clever sky Mar 9, 2017, 11:50 AM

#

Yep.

#

(end - start) vector length

sharp swan Mar 9, 2017, 11:51 AM

#

you might need to move it into position by half the length though as it will probably spawn it using the center as the pivot

clever sky Mar 9, 2017, 11:51 AM

#

and if you use a 1cm tall mesh, you don't have to do any additional work to scale.

sharp swan Mar 9, 2017, 11:52 AM

#

i think you could probably use a custom mesh with a pivot point at the peak and scaling is easier maths wise

dusky moon Mar 9, 2017, 11:52 AM

#

@sharp swan Yes a custom mesh is easier and has less calculations ...

#

I think I got it,,, thanks guys

sharp swan Mar 9, 2017, 11:53 AM

#

gl hf

dusky moon Mar 9, 2017, 12:43 PM

#

@sharp swan @clever sky I just did as you guys suggested ... It seems to work. except that now my pointer flicks alot and the Z updates like every 0.3 seconds ! it's so laggy ... am I doing any thing wrong here ?

📎 Pointer.JPG

clever sky Mar 9, 2017, 12:45 PM

#

Hmmm... well I haven't tried the mesh approach myself (I use a beam emitter particle), so I'll let marc comment

sharp swan Mar 9, 2017, 12:46 PM

#

trace sometimes lags behind when being calculated during Post-Physics. Might wanna check and see if you can set the BP Tick group to Pre-Physics (or it might be the other way around)

dusky moon Mar 9, 2017, 12:47 PM

#

I'm wondering If it needs to push up the trace it might not be so effiecient to do at all with this approach

tawdry dragon Mar 9, 2017, 12:48 PM

#

Hey guys. A question regarding blueprints and GearVR. I am working on a fade function for a material that changes a scalar param, and I was wondering, what is most efficient when changing that param: Timelines, timer or on tick?

sharp swan Mar 9, 2017, 12:48 PM

#

its pretty efficient. In our game you can get upto 20 items on our radar (I have tested it with 1000 and it added 1ms). This is a VR game too that is pushing the draw call count and high poly models

#

@tawdry dragon : if you are asking then you know its not Tick :p So timer or timelines is good

tawdry dragon Mar 9, 2017, 12:50 PM

#

Okay, but doesnt a timeline update on tick anyways, or is it locked?

sharp swan Mar 9, 2017, 12:50 PM

#

its framerate independent

#

it does work in the main thread but for all intents and purposes, consider it seperate

tawdry dragon Mar 9, 2017, 12:51 PM

#

Okay - so the best solution would be a timer, where I can find the interval that is most efficient without any noticeable visual lag

#

or, the most effecient solution*

#

but easiest is clearly a timeline 😄

dusky moon Mar 9, 2017, 12:52 PM

#

hmm got it Marc , I tried changing the Tick group but still super laggy

sharp swan Mar 9, 2017, 12:52 PM

#

if it's flickering, are you spawning them each frame or just modifying the z-scale? Because flickering would indicate a fast cycle of spawn/destroy/spawn/destroy/etc

dusky moon Mar 9, 2017, 12:53 PM

#

No I just made a simple Mesh and made it as a child of my Right Hand controller ... I'm just changing the visibility of it

#

but apart from the Visibility's flicks ... The Z scale updates with annoying interval

#

It's strange because with draw debug line ticks very smoothly

@tawdry dragon I use timelines in my project a lot. Never had performance issues.

sharp swan Mar 9, 2017, 12:57 PM

#

@dusky moon im not sure really as your screenshot looks fine

#

isnt Timeline just a wrapper function for SetTimer really?

tawdry dragon Mar 9, 2017, 12:57 PM

@mighty carbon Cool, will use that then 😃

#

Well, there is also the entire curve editing etc. 😃

mighty carbon Mar 9, 2017, 12:57 PM

yeah thats what I mean. A more functional one

tawdry dragon Mar 9, 2017, 12:58 PM

#

@mighty carbon btw, just an update on my performance thingy. So using the set CPU/GPU level didnt do much, even caused some instabillity. However, because I had rewritten some of the old code, I could update to 4.15 and BAM! Gone from 15 min to >35 min before overheating

mighty carbon Mar 9, 2017, 12:59 PM

#

@sharp swan btw I decided not to mess with figuring out length of the spline. I used triggers with manually set animation playback rate value :)

tawdry dragon Mar 9, 2017, 12:59 PM

#

also did a test with stereolayers, but that crashes the app instantly upon using my GearVR

mighty carbon Mar 9, 2017, 12:59 PM

#

Ouch

sharp swan Mar 9, 2017, 1:00 PM

#

@mighty carbon whatever works is all good 😄

mighty carbon Mar 9, 2017, 1:01 PM

#

@tawdry dragon I think you should use cpu/gpu throttling when they don't do work. Like when you are in the menu, or while loading level

sharp swan Mar 9, 2017, 1:03 PM

#

alternate processes that don't need to be run concurrently too.

wicked oak Mar 9, 2017, 1:07 PM

#

gear vr stereolayers are more limited

#

remember that

#

i think 4 is the max

tawdry dragon Mar 9, 2017, 1:24 PM

#

To be honest, Im at the point where I think my company should just throw money at you guys and solve our problems, instead of me having to learn every technical detail about every facet of software development 😛

#

😛

clever sky Mar 9, 2017, 1:55 PM

#

If you do mobile VR, go lo-fi and charming.

#

Trying to squeeze decent visuals on mobile is like... squeezing nuts!

#

Whatever kinda nuts you're thinking, it's gonna be painful!

wicked oak Mar 9, 2017, 1:56 PM

#

i found that the "auto loading vr splash screen" is broken as fuck

#

but if you toggle it once, it will stop blacking the screen when you load a map

#

wich allows you to do the layers and keep them visible beetween level loads

clever sky Mar 9, 2017, 1:58 PM

#

That's kinda cool.

#

Is that face locked layer? Or 360 sphere head tracking style?

#

Like robo recall

wicked oak Mar 9, 2017, 2:02 PM

#

Tracker origin style, so like robo recall

mighty carbon Mar 9, 2017, 2:05 PM

#

I like working on mobile VR stuff. It's sure pain in the ass when it comes to optimizations (assets especially), but because it's limiting, people don't expect fancy visuals and when you deliver those, people get pretty excited. On PC you already have to compete with AAA companies and that's tough.

wicked oak Mar 9, 2017, 2:07 PM

#

my new loading system is like the robo recall one, but i think the robo recall uses 4.16 improvements

#

becouse similar stuff gets broken on my end

#

so i added a "loading layers" array to the Game Instance

#

when the game instance detects a level load, it uploads the layers and makes them visible, then stores their layer IDs

#

after the level loads, the game mode Begin Play (on the topmost gamemode) calls the remove loading screen once the player spawns

clever sky Mar 9, 2017, 2:34 PM

#

Nice. So what game you working on now?

#

Mech game?

wicked oak Mar 9, 2017, 2:44 PM

#

no, DWVR

#

polishing some stuff for Sony review

native cedar Mar 9, 2017, 3:01 PM

#

did anyone try messing with the 4.16 robo recall version of the engine on his own project?

wicked oak Mar 9, 2017, 3:03 PM

#

no i havent

#

im doing it on my own, this is mostly for ps4 after all

#

there are some very clear requisites to do, and the "have loading screens" is one of them

#

on pc no one gives a shit

#

and it loads fast enough anyway

#

DWVR loads in 0.5 seconds in my pc, i have to copy it to a slow as balls pendrive to test this stuff

native cedar Mar 9, 2017, 3:04 PM

#

what what you need a loading screen mode that works decently with no freezes ad stuff while the ps4 is loading your level?

wicked oak Mar 9, 2017, 3:05 PM

#

you do

#

you are allowed to drop fps while loading

#

most games just switch to 2d mode

#

and use a generic loading screen

#

ok, now that it works 100% on pc, gonna try putting it on the devkit, see how the layers go on PSVR

#

wait, now i see that i keep the ingame hud

#

so thats how robo recall does it

#

sneaky bastards

#

they disable the autoload scren (on by default, blacks out the hmd on loading) and then add their Loading Actor to the screen. This loading actor has a bunch of stereo layer components

#

at switch level fast, it seems they are still there, but they can get deleted once the objet is GCd or something

#

fairly odd

native cedar Mar 9, 2017, 3:12 PM

#

I've never been able to deal with the application freezing when I load a level

#

even if I use level streaming I still get freezing from time to time which trigger vive's thing

#

never did anything in psvr yet

mighty carbon Mar 9, 2017, 3:13 PM

#

@wicked oak didn't I tell you yesterday how it should be done 😉

wicked oak Mar 9, 2017, 3:14 PM

#

you were using a small load level

#

im bypassing all of that

#

im not streaming levels

#

just calling OpenLevel to the level i need

#

no streaming

#

@native cedar thats the idea

#

if you add the stereo layers right, the stereo layers are HMD sdk stuff, they dont care that your game is lagging or is frozen

native cedar Mar 9, 2017, 3:15 PM

#

ooooh

#

so that's what stereo layers are

wicked oak Mar 9, 2017, 3:15 PM

#

they are completely outside ue4

#

they are part of the VR sdk

native cedar Mar 9, 2017, 3:15 PM

#

are they added via c++?

wicked oak Mar 9, 2017, 3:15 PM

#

there is a component for it too

native cedar Mar 9, 2017, 3:16 PM

#

I mean they do not work with ue but somehow you handle them in the application

wicked oak Mar 9, 2017, 3:16 PM

#

stereo layer components do exactly that

#

they automatically call to the SDK to render that layer

native cedar Mar 9, 2017, 3:17 PM

#

on which version of the engine were they added?

wicked oak Mar 9, 2017, 3:17 PM

#

4.13 or sooner

#

been there for a while

mighty carbon Mar 9, 2017, 3:17 PM

#

btw, I am becoming more convinced that mobile VR will fail as gaming platform due to VR being secondary to mobile users. They mostly use it for videos / pics, sometimes for experiences. People who game don't seem to want to fork over $1000 (or $900) for S8 just for VR.

sharp swan Mar 9, 2017, 3:20 PM

#

naah but they would fork it out to look like they got the latest phone with all the new snapchat apps and all that bullshizz

#

id be happy with two cups and a bit of string

mighty carbon Mar 9, 2017, 3:21 PM

#

that was their point when I complained about pricing.. They get latest and greatest phones to show off. Yes, S8 will be awesome for VR, but they don't really case as much for VR as for flashy new phone. Whether I'd be happy with my old Nokia as a phone. I got my S6 simply because of Gear VR (and it was on sale since S7 was already out for some time)

Hi, I'm having a bug using a Vive in Unity, and I was wondering if anyone here has experienced it as well or if it's Unity (or our project?) only. Basically when we use the controller to trigger something, in our case when the player holds the controller in a button then presses the trigger, a second controller appears for a few seconds. This second controller follows the original one, only it's placed a little higher than the actual controller, so it floats right above it. It follows the movement and everything. Anyone else experienced this or know potentially what is causing this?

#

We haven't really changed anything in the code, but all of a sudden it now always does this

mighty carbon Mar 9, 2017, 3:46 PM

#

Last time I checked this was UE4 chat

#

not Unity

fallen wind Mar 9, 2017, 3:56 PM

#

Yes, but as I mentioned, I'm not sure wether it's Unity related or if it's caused by something in a driver update/anything else Vive related

#

Which seems like it may be the case as I haven't changed anything in the code of the game when this started happening, but there may have been an update to steamVR that I hadn't noticed

tired tree Mar 9, 2017, 4:07 PM

#

That doesn't sound like it has anything to do with unity, sounds like its your project.

clever sky Mar 9, 2017, 5:06 PM

#

@fallen wind No experience of what you've reported in any of my projects or any software I've used. Closest would be simple drift causing offset until I power cycle the Vive controller.

mighty carbon Mar 9, 2017, 5:20 PM

#

folks, what do you think about importance of visuals in VR? For example, I don't see a way to make quality content like seen in Robo Recall, Lone Echo, etc. in timely manner with small (like 2-3 people team) working part-time on the project. However something like Quake or MineCraft style is quite feasible to achieve (especially with low poly assets widely available for UE4).

#

from your experience, do people care too much about visuals in desktop VR ?

clever sky Mar 9, 2017, 5:21 PM

#

Having tried many VR experiences... visual cohesiveness matters most.

#

Detail is only a tool to serve that.

#

Also shadows and lighting are important in aiding depth perception.

mighty carbon Mar 9, 2017, 5:21 PM

#

well, that's given. Consistent art style is the key anywhere.

clever sky Mar 9, 2017, 5:22 PM

#

It's not hugely different from normal games in that sense.

#

AAA visuals will always be a big draw.

#

But gamers can and do enjoy other types of art.

mighty carbon Mar 9, 2017, 5:22 PM

#

except there are 100M gamers on Steam and only like 500k on PC VR

#

(I don't really know how picky PC VR gamers are)

clever sky Mar 9, 2017, 5:23 PM

#

Most PCVR gamers understand the current situation pretty reasonably.

#

VR has significant overheads.

#

VR development is small and underfunded.

#

But... they also do compare it to stuff that's out there.

#

So as the overall bar of VR visuals rise, so will expectations.

#

As for what's the expected bar for 'reasonably presentable'... maybe look at something like Onward?

#

It's not a pretty game... but it's ok. Good choice of meshes, good reactivity. Presentation cohesive enough to not draw away from gameplay.

#

By comparison, BAMVR is kinda ugly and amateurish looking.

#

Even though it has a reasonable fan base due to its mechanics.

mighty carbon Mar 9, 2017, 5:35 PM

#

Onward has a pretty high production value

#

no way to make it those characters single handily in timely manner

#

is this BAM VR http://store.steampowered.com/app/525640/ ?

Bullets And More VR - BAM VR

Multiplayer with up to 12 players in Team Deathmatch, Deathmatch and Capture The Flag. Furthermore realistic and smooth weapon behaviour plus a custom scene editor for creating simple and complex scenes in no time and the ability to switch between editing and playing without any loading screens.

#

(looks like different assets put together without even trying to make them consistently looking 😦 )

#

I was thinking of getting this https://www.unrealengine.com/marketplace/simple-apocalypse and making something interesting with it

#

(or maybe one of the other packs they have)

#

it would imagine lighting, environmental/level design and animation would make it different from other projects that use those assets (and gameplay of course)

glossy agate Mar 9, 2017, 5:58 PM

#

So my game uses 360 and room scale but some demo players on touch asked if I can put in snap turns or something because they don't have room scale. Do you think its better to do something like a 30 degree snap turn, or try smooth yaw turning with a joystick? I havn't tried touch so I don't know which experience is better.

#

its one of the first complains on the game, by everyone

#

in VR, the first thing people notice is if everything is logical and cohesive. Robo recall city is very realistic, and the robots all make sense in their slightly stylized way

About my earlier problem, apparently steamVR shows the Vive menu when your PC can't handle something too well. So I guess a problem more in my project, though it can also happen in UE4 and not just in Unity. So if any of you ever have this problem, just make sure your PC can handle the game 😃

They are children (hierarchy-wise) of a SceneComponent called "CharacterMid" which is constantly set to the X and Y location of the Camera.
When the Players Camera turns at least by 35 degree, the "CharacterMid" will Rinterp the rotation towards the Camera.
The Z location is left at 0. The Z Location of the BoxCollisions is currently something like "CameraZ - 50" to kinda match my hips or back.
What is your way of doing that? Is there a known good way of orienting these things? I saw a lot of games that let you equiped things to your chest.

Yours looks pretty good already! May be complicated, but you could maybe average the forward vector of the controller doing locomotion with the forward vector of the camera to get a more likely torso rotation?

neon egret Mar 9, 2017, 6:56 PM

#

That's what I do currently. Forward of CharacterMid dot product Forward of Camera

#

It looks good, but sometimes I grab into nothing on my back as the slow turned a bit all ready while moving my head

glossy agate Mar 9, 2017, 7:03 PM

#

If you figure it out that would be awesome! Especially for games like onward where your crouched down frantically grabbing for ammo but the belts turned all wonky haha.

wicked oak Mar 9, 2017, 7:13 PM

#

give it a lerp, too

#

dont 100% lock it

#

it feels better if it moves smoothly to the target location, less artificial

neon egret Mar 9, 2017, 7:22 PM

#

Thing is, you would also have to fake crouching for the actual position

#

Cause your hips are further behind

#

and your back is slight titled forwards

#

Could they just make these extra trackers a bit more cheap and generally easier available

#

-.-

tired tree Mar 9, 2017, 7:23 PM

#

waist tracking is 100x more important than foot

#

can get way better IK / motion with real waist location

#

even than foot

glossy agate Mar 9, 2017, 7:25 PM

#

Would be cool if the trackers implemented like a basic leap motion or something like that xbox camera tracker to pick up basic body orientation.

neon egret Mar 9, 2017, 7:29 PM

#

Well the full body IK thing with I think 3 extra trackers seems to work quite well

#

2 feet, 1 waist

#

But people are barely buying the full rift. I don't see then buying expensive extra trackers atm

#

Sooo faking it for now

wicked oak Mar 9, 2017, 7:30 PM

#

the chest/waist tracker is the best use case

#

you can then IK the legs

tired tree Mar 9, 2017, 7:32 PM

#

yeah

#

but with only one spare tracker

#

waist + hands + head

#

would be most useful

so, UE4 can already do object tracking ? o.O

#

(see Blackbird tracking vehicle)

tawdry dragon Mar 9, 2017, 7:40 PM

#

Blackbird is tracked using ArrAIy right?

mighty carbon Mar 9, 2017, 7:41 PM

#

no idea

#

I was skimming over looking at the pics 😛

tired tree Mar 9, 2017, 7:44 PM

#

they said they would back port that into the engine in their presentation, don't know how much of that was fluff

mighty carbon Mar 9, 2017, 7:46 PM

#

would be nice for Tango devices (phones) to be able to do object tracking. Of if UE4 had native capacity to use phone camera and do object tracking.

The mesh in SteamVR is a bit off, but it was impossible for me to occlude the tracker with one hand even though I gripped it over the top

mighty carbon Mar 9, 2017, 8:44 PM

#

This is what I am after - a bot that comes up to player (player is stationary), talks some nonsense, walks around player and maybe offers player a choice at the end of its monologue, and then goes away. Should I simply do animation montage for bot character or should I do actual AI ?

glossy agate Mar 9, 2017, 8:49 PM

#

Are both hand trackers, and pods working?

wicked oak Mar 9, 2017, 9:10 PM

#

AI

#

AI that triggers stuff like the montags and speech

#

that so they guy can be dynamic and go to where you are and that kind of thing

mighty carbon Mar 9, 2017, 9:37 PM

#

@wicked oak well, this is just to let player know what controls to use and what to do, generally. Player won't be able to change location as it will be in the black room with menu and stuff. If it's generally better to do as AI, I'd have to do it. If not, I'd rather not waste time on learning AI for this particular project as I don't really plan of having any AI in it.

wicked oak Mar 9, 2017, 9:40 PM

#

you can use the behavior tree

#

as a "do this, then this, then this"

#

a simple Sequence selector, alongside one task for each thing

#

so like "Go To Player" -> Play Animation -> Move There -> Play other animation

mighty carbon Mar 9, 2017, 9:41 PM

#

I see.. So AI's logic is in BTs and not in BPs ?

#

generally, in UE4

#

hmm.. I'd need to dive into AI tutorials

wicked oak Mar 9, 2017, 9:49 PM

#

its on both

#

the BTs is a way to do high complexity AIs in a manageable way

#

a similar thing on the controller would get out of hand FAST

#

and then you cant reuse the tasks

#

a "move to" task is just that, so it can be reused on many enemies

glossy agate Mar 9, 2017, 9:50 PM

#

I was just about to say that too. "Move to" is simple and you can set how close they get to player character.

wicked oak Mar 9, 2017, 9:51 PM

#

for example, i have a FireAt task

#

i use that for ranged enemies

#

the fire at task takes care of stopping, aiming, shooting for X time, and then stop shooting

#

several enemies use that

mighty carbon Mar 9, 2017, 9:55 PM

#

I see

#

so, why would I need AI if player doesn't move and I can just animate bot appearing and moving to specific designated location, play anim montage and the switch anims within the montage based on what player does next (and player will remain at the same location until player chooses to dive into the actual main level) ?

#

@wicked oak you might be able to win something with your game!

glossy agate Mar 9, 2017, 10:00 PM

#

If it has an anim BP it will already do the walking anim for you with the move to. Its not really a real Ai system. Just a simple triggering system.

#

If the character is just standing there and the player walks up to it, you could just use a trigger box to set off the anim.

mighty carbon Mar 9, 2017, 10:02 PM

#

@glossy agate yeah, it's just scripted thing. I don't need AI to do any pathfinding or attacks or do something "intelligent" based on player's actor. It's more like an NPC character than does pre-defined things and in no way can be interacted with physically

#

that's why I wonder if I simply can use actor with anim montage and trigger anims / sounds purely from BP and notifiers

glossy agate Mar 9, 2017, 10:04 PM

#

yeah this method is all done in BP. Its super basic. I use it for drones that chase my character.

#

has no pathfinding though so they can get stuck behind stuff.

mighty carbon Mar 9, 2017, 10:07 PM

#

aye, cool

#

so technically if navigating around obstacles, dynamically, isn't required, it all could be anim montage and Blueprints, instead of fully fledged AI with BTs ?

#

@glossy agate ^^ ?

glossy agate Mar 9, 2017, 10:19 PM

#

Yes. Basically you can simply have them move to a point, or actor or anything.

#

Its good for your game because an anim montage would probably have a set location the player character would have to go to.

#

@mighty carbon This way the player character can be anywhere, and the tutorial would walk up, stop, then you can trigger the tutorial montage.

mighty carbon Mar 9, 2017, 10:38 PM

#

aye, thanks @glossy agate

glossy agate Mar 9, 2017, 10:39 PM

#

Anytime man!

mighty carbon Mar 9, 2017, 10:41 PM

#

oh, also wondering if I need to use Sequencer at all for this purpose.

glossy agate Mar 9, 2017, 10:53 PM

#

I wouldn't. Seems like extra work for something simple.

#

do you have a bunch of fancy anims for it, or is it just like an r2-d2 looking thing rolls up, talks for a bit, then rolls away.

What's best VR for ue?

opal quest Mar 10, 2017, 12:09 AM

Looking at the vive?

#

Any good?

mighty carbon Mar 10, 2017, 12:12 AM

#

@glossy agate something like r2-d2, maybe just a tad more articulate 😊

#

@opal quest Rift + Touch !

opal quest Mar 10, 2017, 12:18 AM

#

Rift is best?

mighty carbon Mar 10, 2017, 12:23 AM

#

the matter is complicated, really

#

what are you going to develop for? Mainstream or enterprise ?

opal quest Mar 10, 2017, 12:32 AM

#

Both

mighty carbon Mar 10, 2017, 12:35 AM

#

Rift has better software, better ergonomics, better games, it's affordable. Vive has larger room scale area, a bit better tracking.

glossy agate Mar 10, 2017, 12:46 AM

#

They are both pretty impressive, i have vive but I heard oculus has a wider fov. Haven't tried it yet to see

opal quest Mar 10, 2017, 1:08 AM

#

Idk if I can get rift in New Zealand

#

I can definitely get vive

#

But it requires a smallish room

#

For the tracking

#

But Oculus just has this boom thing

rugged abyss Mar 10, 2017, 2:21 AM

#

I have both. Vive is amazing out of the box and less intense on physical resources. Much better tracking for 360 and easier to setup. Longer cables etc. Oculus touch setup is a massive pain in the ass in terms of cable length, sensor positioning and USB resources. Very good chance you wont have enough USB channels out of the box for rift, esp if you add a third sensor. If I'd started with Rift in VR I would have swore off VR altogether tbh.. its runs awful on my PCs.

manic axle Mar 10, 2017, 2:25 AM

#

Robo Recall is pretty great visual wise.

pearl tangle Mar 10, 2017, 3:16 AM

#

rift is just $200 cheaper than Vive now. But I think once the trackers start coming out more and the new audio strap and wireless the vive will be a very different beast to the rift

#

definitely going to be the most expensive option but it will be the best option for doing cool shit in vr

#

my tracker should finally get here today too!

mighty carbon Mar 10, 2017, 3:25 AM

#

lol, $660 vs $900

#

and better/more games

#

Rift is a no-brainer

#

unless you plan doing enterprise, don't care for better ecosystem and have a lot of disposable income

#

both systems have 360 deg. tracking

#

hardware requirements are lower for Rift

#

@opal quest ^^

mighty carbon Mar 10, 2017, 3:44 AM

I am in the same boat as Joshua, thus I am offering unbiased comparison. Unlike you, Oculus haters 🙄

#

(comparison from perspective of someone who is going to buy one HMD or another)

real needle Mar 10, 2017, 3:48 AM

#

@mighty carbon Well, we've actually worked with both and I would say what was mostly said before: If you want to develop, get the vive. If you want to release, get both.

mighty carbon Mar 10, 2017, 3:49 AM

#

lol, Vive fanboy talk

#

I am aware of minor issues with 360 tracking on Rift, but that's about it

#

to say Vive is better is just plain arrogant

real needle Mar 10, 2017, 3:52 AM

#

No, that's not about it

#

I've had tons of issues with the plugin for unreal

mighty carbon Mar 10, 2017, 3:52 AM

#

ergonomics are awful, price is too high, research team behind Vive isn't as strong as behind Rift, you don't get to release on Oculus platform with Vive, mentality behind Steam is awful

real needle Mar 10, 2017, 3:52 AM

#

I have to enable/disable the plugin several times because it'll lock at 45fps for no reason

mighty carbon Mar 10, 2017, 3:53 AM

#

vblanco has been developing with Rift for a long time already and he said just recently he had no issues

real needle Mar 10, 2017, 3:53 AM

#

I've had it since the touch dev kits, we've all been around for a while

mighty carbon Mar 10, 2017, 3:54 AM

#

AWS probably - something about dropping below 90 fps will get into 45 fps with AWS. Which is a good thing - you still get smooth tracking and performance

#

err, ASW

real needle Mar 10, 2017, 3:54 AM

#

Lol I'm aware, and a gray scene doesn't hit 45 without actual problems

mighty carbon Mar 10, 2017, 3:55 AM

#

also, how does plugin relate to Oculus? Epic is the one making plugins

real needle Mar 10, 2017, 3:55 AM

#

Actually, Oculus is providing a lot of support for the plugin

mighty carbon Mar 10, 2017, 3:55 AM

#

not really

#

Oculus provides SDK, Epic integrates it

sturdy coral Mar 10, 2017, 3:56 AM

#

@mighty carbon Oculus has their own branch

#

and they get stuff merged from time to time

real needle Mar 10, 2017, 3:56 AM

#

I'm done arguing, and I can't give you any details but it's not done the way you think it is

mighty carbon Mar 10, 2017, 3:56 AM

#

I work with Gear VR and I know Epic skips on certain things for unknown reason. So Epic's branch is always behind / missing features. Not Oculus falt at all

sturdy coral Mar 10, 2017, 3:56 AM

#

@mighty carbon you don't have experience developing with either headset as far as I understand it

mighty carbon Mar 10, 2017, 3:57 AM

#

I have experience with Gear VR

sturdy coral Mar 10, 2017, 3:57 AM

#

ok, so you can probably give great advice on Gear

mighty carbon Mar 10, 2017, 3:57 AM

#

same thing, just no motion controls / positional tracking. The same exact thing - Oculus makes SDK, Epic integrates it.

sturdy coral Mar 10, 2017, 3:57 AM

#

I wouldn't trust that advice vs Daydream unless you have developed with both

mighty carbon Mar 10, 2017, 3:57 AM

#

dude, same company, same kind of software

#

Oculus branch has current SDK, all BP exposed, Epic's 4.15 has old SDK, lacks some important BP funtionality

#

how on Earth this is Oculus' fault ?

sturdy coral Mar 10, 2017, 4:00 AM

#

I don't think it is, I was only responding to oculus makes SDK, epic integrates it; Oculus in fact does some of the integration work sometimes and epic merges it

#

the main pain points with rift for dev are the health and safety warning and the display turning off faster when it isn't worn blocking out the mirror view; there might be some workarounds

pearl tangle Mar 10, 2017, 4:02 AM

#

there are several of us here that have both/ all hardware

#

Rift costs $600, Vive costs $800. The vive ecosystem will be far far larger than rift due to it's flexibility

#

both are cool hardware, but Vive will dominate in a lot of areas. For early adopters a couple hundred bucks is rarely a deciding factor

sturdy coral Mar 10, 2017, 4:09 AM

#

depends on your playspace size too, by the time you add 4 cameras and all the usb shit you have to buy they are about the same price

real needle Mar 10, 2017, 4:18 AM

#

The new audio headstrap makes the vive more comfortable and people with glasses can actually play with the vive

#

A developer should also be interested in developing for an ecosystem that will soon be releasing several headsets a year, whereas Oculus can't do more than 1 (at most), and I highly doubt they will be providing reference designs for other manufacturers like Valve does

sturdy coral Mar 10, 2017, 4:29 AM

#

I'm looking forward to wireless too

real needle Mar 10, 2017, 4:30 AM

#

@sturdy coral Yeah it seems to work pretty well, but the greatest benefit for my day to day would be to use it at the office, and the current wireless solutions can't do more than 1 in the same space

#

So I guess it'll be a rock paper scissor game when it arrives...

mighty carbon Mar 10, 2017, 4:46 AM

#

@pearl tangle in a long run Vive won't dominate

#

it's all about mass market, and Vive isn't suitable for it

#

plus RIft has better library (higher quality)

pearl tangle Mar 10, 2017, 4:48 AM

#

Mass market is China. There are more potential customers in China than the rest of the world combined

#

HTC owns Chinese hardware and software market and arcades

sturdy coral Mar 10, 2017, 4:48 AM

#

@mighty carbon the full Rift library works on Vive

mighty carbon Mar 10, 2017, 4:48 AM

#

China is a black hole

#

first, one can't be in China without being represented by a Chinese company

#

second, China is all about arcades and f2p

#

good luck for small team making money there

#

@sturdy coral not exclusives

sturdy coral Mar 10, 2017, 4:50 AM

#

@mighty carbon which one?

mighty carbon Mar 10, 2017, 4:50 AM

#

(maybe through Revive?)

sturdy coral Mar 10, 2017, 4:50 AM

#

yes, through Revive

#

Revive has less bug reports than steamvr does for rift users

#

so if you want to play everything, go for Vive

mighty carbon Mar 10, 2017, 4:50 AM

#

anyone have experience compiling BLUI?

if so, do you think it's worth it (performance vs. utility tradeoff in VR) for me to work on troubleshooting the compiler script so it actually works for me?

tawny storm Mar 10, 2017, 5:31 AM

#

I managed to get it to compile but it wasn't an issue with the version I was working with. It was pretty good but it depends on what you want to use it for

winged shale Mar 10, 2017, 5:31 AM

#

it seems pretty cool to me, what with the small chromium running alongside the engine, rendering to texture, but that sounds a lot like it might be performance killing, especially for VR things

#

@tawny storm how does it differ from Epic's web browser subwidget

tawny storm Mar 10, 2017, 5:32 AM

#

the perf seems okay, but that depends on what you let the user get away with: one page is probably fine depending, but heavy scripts obviously will impact perf

winged shale Mar 10, 2017, 5:32 AM

I would be writing my own pages and using it for UI mostly

#

C2220: warning treated as error - no 'object' file generated warning C4334: '<<': result of 32-bit shift implicitly converted to 64 bits (was 64-bit shift intended?)

#

so

#

it's saying there's a flag telling it to treat all warnings as critical errors

#

finding that error about a 32bit shift being converted to 64 which generates that warning

#

which then is considered critical (probably isn't) and fails

#

so either find the place it's doing that and fix it to really be 32 or 64 bit (not sure what to do there without it in front of me, and I'm not bit-wizard) or just turn off the warnings-as-errors flag

#

not sure what that is or where to change it but i'm sure some poking and searching will find it

thanks mate

tawny storm Mar 10, 2017, 5:40 AM

#

np, shouldn't be too hard to get it past that warning

#

once you've got it compiling BLUI is pretty nice for sure

#

No @pearl tangle . It just worked when i turned it on. Not sure why. I'm assuming the computer thought another application was using the VR or something.

how do they not have aliasing in robo recall with msaa L_L

#

I put msaa in my fwd project and there is stil aliasing here and there

wicked oak Mar 10, 2017, 9:50 AM

#

becouse you have specular aliasing

#

robo recall assets are made in a way that they dont alias much

#

and it has some forward renderer feature that lowers roughness on high angles, so it doesnt sparkle

native cedar Mar 10, 2017, 9:59 AM

#

specular aliasing huh

wicked oak Mar 10, 2017, 10:35 AM

#

specular aliasing is basically sparkles

#

from the normal maps and stuff

#

there is ways to make it better, like creating the roughness texture mipmaps in a way that it gets progressively rougher

#

i dont know if ue4 does that

native cedar Mar 10, 2017, 10:38 AM

#

It does

#

I just googled specular aliasing unreal and found a nice forum post

Even if it does not one could make a material function for that I guess

wicked oak Mar 10, 2017, 10:40 AM

#

there is a tickbox on the forward renderer features on the material

#

it lowers roughness on high angles to avoid sparkles

#

or something

native cedar Mar 10, 2017, 10:41 AM

#

What concerns me is static shadows from long, linear shapes

wicked oak Mar 10, 2017, 10:43 AM

#

thats shadow resolution

#

nothing you can do about that

#

but upping that shadow resolution

native cedar Mar 10, 2017, 10:44 AM

#

still when they are far there is aliasing

#

it's a line from a texture

#

hi. how can i manually correct the camera height of my pawn when in vr? its a oculus so i'm using "set tracking orin floor" - but i need to substract some cm in height

native cedar Mar 10, 2017, 10:44 AM

#

msaa does not deal with that

agile stirrup Mar 10, 2017, 10:58 AM

#

set base rotation and base offset in meters 😃

sturdy coral Mar 10, 2017, 1:01 PM

#

I think there are two methods of fixing specular aliasing in the forward renderer, the checkbox does it in screen space by comparing how much the normals are varying

#

but there is another method that bakes it into the texture mip levels that is supposed to be better

#

@native cedar you might have had a problem too if you didn't set the r.MSAACount variable

mighty carbon Mar 10, 2017, 1:04 PM

#

Weren't they going to fix specular aliasing if forward renderer soon?

sturdy coral Mar 10, 2017, 1:06 PM

what do you mean?

mighty carbon Mar 10, 2017, 1:15 PM

some hybrid AA?

Just saying 😊

sturdy coral Mar 10, 2017, 1:18 PM

I didn't hear about hybrid AA but I've read somewhere that specular aliasing will be fixed. Maybe I am mixing things up.

yeah a bit about that, should be cool. I definitely want to experience the UI design of it the most

native cedar Mar 10, 2017, 3:12 PM

#

about the AA thing, I think in VR there is no current solution

#

I customized the engine to have both msaa and fxaa, would probably be able to get msaa and txaa easily, but the thing is it costs just too much

#

I don't even think msaa and fxaa is better than msaa alone tbh

#

after a long, long, long, long journey I concluded that due to performance needs, aliasing is fought via msaa and best practices, maybe some supersampling if the performance allows but that's it

#

forward, msaa, some supersampling, making assets properly and designing around issues

mighty carbon Mar 10, 2017, 3:18 PM

#

well, you just have to live with MSAA in VR 😃

#

just like back in the days we had a lot of rendering limitations in games and we accepted it, same thing we have to do with VR

#

as tech evolves, we probably will have a good solution for aliasing in VR

agile stirrup Mar 10, 2017, 3:51 PM

hey vr devs - how do you recover from motion sickness while developing? it sucks 😃 forced to do a lot of rest this day

mighty carbon Mar 10, 2017, 3:56 PM

#

well, you are obviously doing something wrong 😃

#

I am quite susceptible to motion sickness, but I don't get any during development of my project because I made sure my locomotion system is designed not to cause it

agile stirrup Mar 10, 2017, 4:02 PM

#

ok - I was just playing around with different stuff and projects today - so no sickness prevention in these projects yet 😉 but driving a car in VR for hours is ... heavy - and just walking around in the realistic rendering room to check performance was too much for me now - I go to regular development for the rest of the day :)
may I ask what your lokomotion look like that you keep feeling fine? I definitly have trouble if I stay on my chair while testing things out with a lot of head movement

mighty carbon Mar 10, 2017, 4:10 PM

#

interesting, I would expect not to have sickness if you have fixed reference point (cockpit, interiors of the car, etc.)

sharp swan Mar 10, 2017, 4:13 PM

#

could just be natural motion sickness. I get it even with a fixed point at times. Less so after 2 years but still some

#

even the military grade VR states you cant drive for 3 hours after

agile stirrup Mar 10, 2017, 4:18 PM

#

ok - so it is getting better over time? good to hear 😃 i'm relative new in this. but I stop for today, because I NEED to drive in half an hour.
while driving in vr i'm in cockpit perspective, with steering wheel and interitour - it doesn't really help. best is 3rd person behind the car so you see the full chasis - but it is not really immersive when doing this. when moving a character pawn walking is ok, looking around is ok - but please not both at the same time 😃 I'm planning to play around with shrinking the viewport while turning the HMD - maybe this's going to help

mighty carbon Mar 10, 2017, 4:19 PM

#

ha, I don't know about getting better over time - I still get sick instantly if it's conventional FPS locomotion in VR

spiral zephyr Mar 10, 2017, 4:20 PM

#

I feel bad when FPS goes low

agile stirrup Mar 10, 2017, 4:22 PM

#

what helps you out for locomotion? i've seen a few approaches with swinging the controllers to move or so. or do you all only teleport around? Low fps is a good idea, I keep an eye on it. thanks

mighty carbon Mar 10, 2017, 4:23 PM

#

I actually don't get as much sickness from lower fps on my Gear VR

wicked oak Mar 10, 2017, 4:23 PM

#

never run into bad fps

#

even while developing

#

you gonna regret when you have to rework half the game becouse it runs slow

#

have performance in mind from day 1

#

never be slow

agile stirrup Mar 10, 2017, 4:24 PM

#

yes, my projects are really lightweight - no heavy modesl and no heavy material (at the moment)

mighty carbon Mar 10, 2017, 4:24 PM

#

teleportation locomotion is the only one that doesn't make me sick (I'd imagine physically walking in the room scale setup wouldn't get me sick either, but Gear VR has no positional tracking)

clever sky Mar 10, 2017, 4:24 PM

#

Anyone else tried Mission ISS?

#

International Space Station game/sim for the Oculus Rift for the curious.

#

The game has a '2 hand rotation' function where you can grab and rotate the entire world with two hands in complete 360.

#

I didn't get motion sick while using it...

#

But now I've stepped out of it, my vestibular sense has gone wonky as hell.

#

Like initially I kinda lost my understanding of up.

#

The world would feel like up was the up direction of my head... and if my head was titled, the world would feel tilted as well.

#

Even now, after 20 minutes out from it... I still get a slight sense that the world is a little pitched or tilted...

agile stirrup Mar 10, 2017, 4:28 PM

sounds horrible 😄

clever sky Mar 10, 2017, 4:29 PM

Haha... well, it's not quite motion sickness.

#

But it is weird!

@clever sky I bet being at the actual ISS in reality would cause a similar effect

mighty carbon Mar 10, 2017, 4:30 PM

welcome to space 😃

clever sky Mar 10, 2017, 4:30 PM

#

@sturdy coral yeah. Like after a bit of acclimatizing, you just end up ignoring your vestibular sense.

I bet that's what astronauts experience coming back to Earth

sturdy coral Mar 10, 2017, 4:31 PM

how is the quality? I will try it out soon

clever sky Mar 10, 2017, 4:31 PM

#

Actually found that my proprioceptive system was more informing me of my sense of up then vestibular.

agile stirrup Mar 10, 2017, 4:31 PM

#

I'm not sure if for ADR1FT is an update planned with oculus touch controllers - but this was heavy for me to play 😃

clever sky Mar 10, 2017, 4:31 PM

#

The quality is pretty great. Just need to go into the options and turn up the quality setting.

#

FYI - you access the options by pressing X on the left controller, which will spawn a tablet in that hand... then using the right controller, use the point finger gesture (index lift off completely, thumb touching surface), and stab the little 'settings' icon in the top right corner of that tablet.

#

It's cute, but kinda bad UI design.

#

You can also turn on 2 hand grabbing rotation in that menu. Otherwise you rotate by using the right thumbstick.

#

ADR1FT was terrible for me.

#

As far as motion sickness goes.

#

Really bad controls as well... and lack of motion controller support.

#

Just bad bad bad all around.

#

Well, they've moved to a PC-like architecture for that reason right?

mighty carbon Mar 10, 2017, 4:43 PM

#

basically at this point, if you have decent CPU and enough USB ports, it will cost about the same to get into PC VR or PS4 VR, except if you go with PS4 Slim, you don't get the same level of visual fidelity as with Rift.

sturdy coral Mar 10, 2017, 4:43 PM

hopefully this console gen being 8 cores will drive a lot of innovation in mulithreading engine performance

#

the GDC talk last year of the the uncharted 4 multithreading approach was good

#

but adds a frame of input latency which would be bad for VR

mighty carbon Mar 10, 2017, 4:52 PM

#

well, you have rendering on one thread, game on another, sound on another and input on another

#

that alone should be pretty good

sturdy coral Mar 10, 2017, 4:53 PM

#

@mighty carbon and you still have 4 sitting idle

mighty carbon Mar 10, 2017, 4:53 PM

but it comes down to whether it's better to split game thread into those 4 threads and face issues with mounting complexity of the code and debugging issues, or leave it as is

its a worst case scenario

mighty carbon Mar 10, 2017, 4:56 PM

if it is, why Nvidia pushes their AI on GPU ?

#

(not for games of course)

wicked oak Mar 10, 2017, 4:56 PM

#

nvidia AI is not game AI

#

it has nothing to do with it

#

nvidia AI uses neural networks,games use hardcoded behaviors like state machines/behaviortrees/that kind of thing

#

neural networks are essentially massive matrix calculations

#

thats why they run fast on GPUs

#

but normal game AI ends up "if this then that"

gpus really dislike that

clever sky Mar 10, 2017, 4:57 PM

Yeah, game AI are clever scripts.

wicked oak Mar 10, 2017, 4:58 PM

you could do mass pathfinding on a GPU

that, sure

but not decision making

clever sky Mar 10, 2017, 4:58 PM

#

Neural nets are computational models of biological neural functions.

Like every neuron in your brain is kinda like its own slow pokey 200Hz processor.

sturdy coral Mar 10, 2017, 4:59 PM

I think we will see games using some of that stuff, but mostly discriminators that have been trained offline and not a lot of live training during play

some games do it

clever sky Mar 10, 2017, 4:59 PM

#

Yeah, NN stuff isn't really for live gameplay, but for system training.

wicked oak Mar 10, 2017, 4:59 PM

#

it used the neural net to evaluate if it was worth to attack or to defend

#

so if it has X attack power with Y health, vs Z attack power fo the enemy

clever sky Mar 10, 2017, 5:00 PM

#

But that's using a trained NN system (I'm guessing).

#

Which requires less computational power.

mighty carbon Mar 10, 2017, 5:01 PM

#

I'd imagine pathfinding/navigation takes a lot more than decision making. So having those on GPU would help a lot.

wicked oak Mar 10, 2017, 5:01 PM

not that much

unless you are going to do massive amounts of AIs

#

also ray cast can be on gpu

clever sky Mar 10, 2017, 5:03 PM

sturdy coral Mar 10, 2017, 5:09 PM

use box reflections for most of the scene, and put in any big objects that aren't along the wall into the always include list

then add all dynamic actors to the list

not all scenes can work well with box reflections, but robo recall is almost ideal for it with the buildings

clever sky Mar 10, 2017, 5:10 PM

I'll have to do a closer observe of it later.

#

I've essentially just been enjoying the game 😄

#

Even appreciate the teleportation system now that I've gotten used to it.

#

Which sounds weird... but I appreciate that they balanced the game around the limitation of forward facing teleportation.

#

By giving you slow downs after coming out from teleportation. So as to reward you for teleporting often.

sturdy coral Mar 10, 2017, 5:11 PM

#

yeah, main thing I felt didn't feel good was you couldn't quickly turn in place

#

you had to teleport again to turn

clever sky Mar 10, 2017, 5:12 PM

#

As a way to counteract the fact that you'd have to teleport to turn around.

sturdy coral Mar 10, 2017, 5:12 PM

#

ah yeah I didn't notice slow downs were tied to that

clever sky Mar 10, 2017, 5:12 PM

#

Yeah... basically means that you can and should teleport around frequently to avoid bullets as much as possible.

#

Managed to get my scores quite high once I got used to that idea.

#

Playing the game in 360 style tends to make you physically turn around to face them rather than teleport around a lot I found.

#

Which is the most intuitive and obvious way to play.

#

Which is why everyone kinda moaned about the way it worked 😃

in 180 I felt frustrated just when robots would come up right behind me, try to grab them and your hand flys off into space because it lost tracking

#

It feels like getting used to looking by only turning your body and never your head or something

Did you reach around to grab?

#

Yeah... it takes some training to suppress the 360 instinct.

I just turned like half way with my upper torso and reached

#

head-look locomotion orientation always felt unnatural to me in a similar way

#

cause you would like look at something just to look, and it would pull your feet out from under you

#

Yeah.

#

because you forgot this natural thing was controlling as well

Who gave the advice to use head look as the forward vector?

#

It's bloody terrible advice.

you have to like surpress your normal instinct

Academic VR researchers found that stuff back in the 90s!

#

no one, I never used it as one

#

I just always thought it felt bad when I tried it in DK2 demos and stuff

#

That head look as forward was a bad idea.

#

I mean... I kinda understood it before we got decent motion controllers out of the box.

#

But for some reason that idea is still persisting among some developers!

#

yeah, it is really unnatural

#

looking at things is so fundamental

#

you can't take that away to use it as a control scheme
