if they would do some great VR platform on xbox one x with good roomscale I would immediately support it
wicked oak
thats why im interested
its boneheaded to think that microsoft wont put those vr headsets on scorpio
they are the same price as PSVR, and they are higher quality
even if they are inside out, they probably have better tracking
btw, xbox scorpio has a shit CPU
it does have gpu in spades tho
wicked oak
6 usable cores if its like ps4, and drawcalls being nearly free
microsoft marketing said that the scorpio gpu has special features around DX12 stuff. To implement part of the stuff in hardware instead of having it on the driver side
it would be really good for VR
full junco
ok
btw, the new rift smells great
rift aroma is better than the vive one, quite sure about that
and I still didn't get any image to show up in my rift with my game using steamvr
wicked oak
pstd flashbacks about the DK2 glue smell
full junco
oh it was that bad?
full junco
yes I do
wicked oak
uhm
full junco
I should try some other steamvr app I guess
didnt test anything there yet
yeah, also doesnt work
rift only shows "please wait" in that white environment
should I see my steamvr environment in the rift?
I think a steamvr restart fixed the issue 😄
its really annoying how the image gets warped in the rift though
is it normal that the rift has way more warping of the image than the vive?
full junco
and for some reason my game still doesnt want to show up in the rift
other steamvr games work
in the steamvr mirror window it looks correct, my game is visible there, but in the rift it only says its waiting for the game exe
frosty robin
Okey.. wierd bug.. suddenly all of our scenes ( not steam HOME) makes it feels like we are way to tall and the world is too small.
Using the same VR scale (100) aswell as the same Pawn base height (180)
tried recalibrating roomsetup, restarting computer and switching USB ports.
feels super strange.
mighty carbon
interesting.. what else they are gonna come up with this time ?!
@pearl tangle any insight ?
wicked oak
@mighty carbon its kind of a given
i wonder if they will give it extra stuff
or if it will just be like every other gearvr, just a fairly dumb mount
mighty carbon
I think it will be just plain 2017 Gear VR with extra slot for Note 8
wicked oak
thats by far the most probable thing
things that could be improved is designing gearVR so passthrough camera works better/easier
and if that works, they might even do like AR Kit in iphone and offer basic positional tracking
but i doubt arkit is good enough for vr
frosty pumice
Which hardware do i need to buy to start VR?
mighty carbon
depends @frosty pumice
Galaxy S7 + Gear VR or Galaxy S8 + Gear VR + Daydream Viewer for mobile VR
full junco
finally I got it to work @wicked oak I had to disable the oculus sdk, then it worked. I fixed the bug with packaged, so works fine now
full junco
well rift is cheap, vive isnt. if you have enough money to buy a vive, you would probably also buy a 1080 and a i7
who would use a i3 for developing games? thats torture. you dont want to wait forever for a shader compile or an engine recompile
frosty pumice
i got 1060GTX 2GB and have 16GB
mighty carbon
There is no such thing as 1060 with 2Gb... Maybe 3Gb ?
frosty pumice
oh 3 right
frosty pumice
i7 6720
mighty carbon
plenty
@full junco I use i3 and that will ensure that my game runs on lower end hardware
runs well that is and looks decent enough
full junco
@mighty carbon yes its good for that, and you are not using c++ so you don't feel the pain as much, but its still far, far from ideal for developing with it
frosty pumice
@mighty carbon http://www.samsung.com/en/wearables/gear-vr-r323/
So, thats OK for UE VR?
mighty carbon
but if you develop on top end hardware, your product will never be optimized for lower end hardware.. If I had enough free cash and physical space, I'd definitely have high end dev rig and low end test rig
full junco
@mighty carbon yeah, for testing its great. but devs usually care more about productivity than having the low end hardware to test
full junco
a low end GPU doesn't really hurt your productivity, but a lowend CPU really does
mighty carbon
@frosty pumice if you have Galaxy S6/S7 phone, yeah
frosty pumice
Nope, i want to develop on PC
mighty carbon
then Rift or Vive is what you want
if you loaded with cash, get both Vive and Rift 😃
if not, get Rift
mighty carbon
you need 2 USB 3.0 controllers on your mobo - one controller (and 2 ports) for 2 sensors, another (and another 2 ports) - for HMD and third sensor
ok, get Samsung but don't bitch that it doesn't work with PC, because Gear VR only works with Galaxy S6/7 smartphones
frosty pumice
ergh im not sure...
mighty carbon
oook... maybe someone else can help you
fair hearth
just to clarify here,
the gear vr is essentially the same as a google cardboard in terms of functionality, a pc headset (rift/vive) is what you'd want to do pc development, you can use a pc to develop for the gear vr, however your project would have to be mobile based and would only work for the gear vr unless you code it for cross platform
please be more kind, the world needs it, thanks
wintry escarp
the Samsung gearvr does nothing on its own, it needs an expensive phone
mighty carbon
sure, but hey, it's common sense to read about Gear VR and see that it only works with smartphones.. If an individual doesn't understand that, sorry, but no, individual needs to go back to school
full junco
isnt gearvr+phone way more expensive than a rift anyways?
mighty carbon
the point is this person asked how to start developing for VR.. I literally told him/her what (s)he needs for mobile and desktop VR.. Then the person goes on I want Gear VR + PC.. Red flag right there..
full junco
youre a bit too sensitive
not everyone has to directly understand that gearvr doesnt work with PC
mighty carbon
yeah, cuz I am sick and tired of people not willing to do some basic googling and reading
you kidding, right ?
full junco
no, I'm not
mighty carbon
that's dumb, sorry
full junco
imagine you would show your mother a rift and a gearvr, would you expect her to immediately understand that one is for mobile and can't work with a PC and the other one is for PC and can't work with mobile?
mighty carbon
if one can't grasp such basics, one doesn't need to be delving into more complex things .. It's like if you don't know ABC, don't bother writing a short story or read a book
my mother wouldn't be asking how to start developing for VR
she wouldn't even be able to get into Discord ue4 #virtual-reality channel
this person is here not by accident
full junco
well, if she would somehow manage it, maybe congratulate her first on getting into this channel before being super sensitive after she doesnt understand something immediately
mighty carbon
anyone who ends up here are here with particular purpose and reason
one doesn't go into college without first going into kindergarten, then to school
before going into full on VR development, one goes to Reddit, then gets VR system, then tries it, then goes to do basic UE4 development, then starts with VR.. That's common sense that somehow is missing in many nowadays
glossy agate
Anyone try this yet? Was going to buy this game this weekend, been following it for a while, built in UE4 with a grant. Something went wrong though, people are saying perf and locomotion system is really bad. http://store.steampowered.com/app/442660/The_SoulKeeper_VR/
tired tree
oh? they teleport back from intersection? Thats disappointing, I thought when I was talking to them that they were doing something like what I have instead.
glossy agate
From what I read its click to walk, and movement based on HMD forward vector
mighty carbon
I sent my project to Oculus.. Will see if it's their bug or something I messed up
wintry escarp
gearvr one?
mighty carbon
yep @wintry escarp
mighty carbon
sturdy coral
@glossy agate one of the soulkeeper guys was in here a few weeks back
glossy agate
Saw the update log on steam, looks like they are already working on the locomotion fix so I may still grab it this weekend.
full junco
isnt the price really high?
glossy agate
Yeah pretty steep, but if it's great quality with content I would pay. I got both serious Sam games that I think were more expensive than this.
@mighty carbon we gonna coop KF? I'm really happy they decided to add in smooth locomotion.
wintry escarp
will lowering the power limit on my 1070 with afterburner reduce its top speeds to quieten it, or just make it flakey
full junco
@wintry escarp it will make it quieter and slower
what 1070 do you have that you actually hear it? those GPUs are so efficient and take to few energy, you have to have a really bad cooler to hear significant noise
your fan curve is probably setup very bad, fixing that will fix noise and GPU will still be fast
wintry escarp
it probably isn't bad, just the rest of my pc is near silent
ssd, soundproof case etc
noctua fans on slowest settings
full junco
well ok, compared to nothing everything is "loud"
I really have no issue with being able to hear that my PC is under load
wintry escarp
i'll leave it at 90% power and see how that goes when I'm in vr
wicked oak
meanwhile, the new vega has the same power as a 1070/1080, while using twice the power XD
dammit AMD
wintry escarp
huge difference, 100% must just push them into where they start ramping up heat
fan didn't go over 55%
wicked oak
they seem to be good for mining tho, people are grabbing them for that
wintry escarp
amd always good for mining now
volta is supposed to be massive for it, almost guaranteed to be crippled to hell to save sales of their compute cards
full junco
@wicked oak AMD still seems to have almost all the new hardware features disabled on Vega though
wicked oak
a fucking disaster
full junco
so either their hardware is kinda broken, or they are just super super slow with their driver team
wicked oak
i doubt that thing can be saved
if it can, it will be the turnaround of the century
just imagine the driver log
"we enabled some features, games now run 70% faster, deal with it nvidia"
full junco
it would be great
my game runs really nice on rift now
its awesome how steamvr actually maps the vive controller to rift without me having to do anything
mighty carbon
@glossy agate I haven't gotten it yet. Trying to wrap up my Gear VR thing before I get to anything else.. But we might, if it's any good 😃
glossy agate
Cool, Ill need a bit of time too until its ready for Revive
mighty carbon
@wintry escarp I thought you got 1060\
full junco
@wicked oak ah yeah, they are rotated incorrectly
I meant the buttons are mapped
so I can use the touchpad buttons on rift without actually doing anything in code
glossy agate
Its just pitch I think that is off. You can use a second socket, or just set a rotation offset depending on HMD used
full junco
one thing thats annoying is that it now really matters how UE4 randomly switches the controllers, so left/right is sometimes wrong. didnt matter with vive since you can just pick the other controller up, but with rift it matters
what was the solution for the left/right issue with the controllers?
wicked oak
just steamvr stuff
they are not switched randomly
in your motion controller with Right, it will allways be on the Right touch, at least with the oculus sdk
for the steamvr, i dont know
full junco
it appears random to me
I think I read someone saying how to fix it here, a few months ago
@tired tree maybe you?
tired tree
4.17 fixes that
it was epic assigning random left/right, steamVR has saved / preferred already
in 4.17 they actually check with steamVR
its a simple addition to the motioncontrollers also
can merge it in to older versions
full junco
ah great, do you know which commit?
tired tree
was a large merge, just load up MotionControllerComponent and the PollController function
it has two new paragraphs there to check and assign correct hands
full junco
thanks!
mighty carbon
4.17.1 fix is out
full junco
@tired tree it uses EControllerHand::AnyHand, AnyHand doesn't exist in my version though
tired tree
ah.....
well you will have to force it to use the code then
that settings says to use the steamVR setting
full junco
so I should do what?
tired tree
actually
you know what...
I don't think that code serves its purpose
I think its a fallback if only one hand is connected / to make it work with GearVR
I was thinking of the wrong thing
full junco
oh
tired tree
they might have added to the steamvr plugin as well, I don't remember what changed there for 4.17
full junco
are you sure the left/right issue was definitely fixed in 4.17?
tired tree
I could swear I saw something regarding it
but haven't actually tested, may be faulty memory
full junco
I guess here
SteamVRController.cpp
its a lot of stuff changed there though, hard to just merge in an older version. did no one ever made some dirty fix for that before 4.17?
I think it might work
sturdy coral
@full junco did you use roughly Valve's algorithm from GDC 2016 for driving the adaptive resolution changes?
it seems to be a bit aggressive in that it can have a lot of resolution changes in just a few frames
and there seems to still be some overhead that causes some cpu spikes for me when I change resolution. I tried profiling a bit and one area that seemed to show up in the spikes was compute light grid
full junco
@sturdy coral I used that from gdc 2016, yeah
it is pretty agressive
I never saw any cost associated with resolution changes though
sturdy coral
I'm going to try on some simpler scenes
I think the light grid is used on reflection captures too and I was trying on a scene with a bunch of them
full junco
I only tried with fully dynamic scenes
sturdy coral
k, I'll try that too. do you have the overall project setting for dynamic too?
"Allow Static Lighting" false
full junco
yeah I have that set to false
sturdy coral
@full junco ^-- yeah it looks like it is actually GPU. the "other" part on the GPU graph can include compute shaders, and in the profiler I see that computelightgrid thing match up really well with the spikes (and it calls a compute shader)
I'll try with 4.15 a bit later and see if that helps
they move more and more stuff to compute shaders each release
full junco
@sturdy coral ok
sturdy coral
all I have it doing there is walking up and down like .1% each frame
full junco
in 4.15?
sturdy coral
or rather walking up .1% each frame until res has increased 2% total then walking back down
4.16, I'm going to try 4.15 now
this is what I'm using to set it right now:
{
const float MaxMultiplier = 2.0;
const float MinMultiplier = 0.4;
if (ScreenMultiplier > MaxMultiplier || ScreenMultiplier < MinMultiplier)
{
return false;
}
#if STEAMVR_SUPPORTED_PLATFORMS
FSteamVRHMD* SteamVRHMD = GetSteamVRHMD();
if (SteamVRHMD)
{
const int32 EyeResX = 1080;
const int32 EyeResY = 1200;
const int32 MaxResX = EyeResX * MaxMultiplier;
const int32 MaxResY = EyeResY * MaxMultiplier;
int32 MultipliedEyeResX = EyeResX * ScreenMultiplier;
int32 MultipliedEyeResY = EyeResY * ScreenMultiplier;
SteamVRHMD->AdaptiveQualitySettingsGT.EyeMaxRenderViewport[0] = FIntRect(FIntPoint(0 , 0), FIntPoint(MaxResX - 1 , MaxResY - 1));
SteamVRHMD->AdaptiveQualitySettingsGT.EyeMaxRenderViewport[1] = FIntRect(FIntPoint(MaxResX , 0), FIntPoint(2.0*MaxResX - 1 , MaxResY - 1));
SteamVRHMD->AdaptiveQualitySettingsGT.EyeRenderViewport[0] = FIntRect(FIntPoint(0 , 0), FIntPoint(MultipliedEyeResX - 1 , MultipliedEyeResY - 1));
SteamVRHMD->AdaptiveQualitySettingsGT.EyeRenderViewport[1] = FIntRect(FIntPoint(MultipliedEyeResX, 0), FIntPoint(MultipliedEyeResX * 2 - 1, MultipliedEyeResY - 1));
SteamVRHMD->AdaptiveQualitySettingsGT.PercentageOfMax = ScreenMultiplier * (1.0/MaxMultiplier);
SteamVRHMD->AdaptiveQualitySettingsGT.RenderTargetSize = FIntPoint(MaxResX*2, /* both eyes add to x, so double it*/
MaxResY);
SteamVRHMD->AdaptiveQualitySettingsGT.valid = true;
return true;
}
#endif
return false;
}```I did notice one thing the oculus plugin does is pad by a multiple of 16 or something, I didn't add in anything like that
full junco
I just copied exactly what the code in the oculus plugin does
to set the AdaptiveQualitySettingsGT
sturdy coral
ah ok
they have a bug in that too that is fixed in 4.17 if you want to backport it
only affects you if you are supporting the oculus plugin, where they ask the api for the new screen percentage they were applying it directly instead of taking the sqrt of it
{
PixelDensity *= FMath::Sqrt(AppPerfStats.AdaptiveGpuPerformanceScale);
}```well I'm not using the oculus plugin for now
and even if I would I would probably try to make sure that uses the exact same code like the steamvr one for the adaptive resolution stuff
sturdy coral
@full junco still on 4.16, I found a cvar for the lightgrid and it fixed all the hitching
full junco
ah nice
sturdy coral
r.forward.lightgridpixelsize
defaults to 64 and I bumped it to like 512
I'm not using forward, but I guess translucency or something still does
uneven moon
My tools froze up, I can't select the rotate or scale tool, only move (it happened after I started working on Matinee)
Any ideas?
pearl tangle
matinee or in sequencer? Matinee often has issues that do that. Best bet is usually just a restart when those things happen. You can sometimes kick it back in by toggling the rotate and scale tool and trying some different sides and angles and changing local to global

Modelling, materials, programming, animation even the filming, directing, 360 video and being the talent in the videos.
sturdy coral
@full junco I made a dirty hack to fix it, instead of a light grid pixel size I'm dividing by a constant light grid divisions to derive the grid pixel size each frame
right now it requires the aspect ratio to be 1:1 though, with the normal aspect ratio there were cases where you would scale just enough that the x or y rounded over into adding an additional column or row to the light grid but not vice versa
real needle
Does this ring a bell for anyone?
OCULUS: Error: ovr_SubmitFrame called with unrecognized frameIndex (13). Make sure it matches a frameIndex value passed to ovr_GetPredictedDisplayTime
OCULUS: Error: WaitableTimer slept too long/short (i.e. 2.313007 ms)
It crashes the build
This is when playing with a rift connected. On a vive it works.
mighty carbon
@pearl tangle PM 🙂
mighty carbon
Apparently Killing Floor VR isn't that great.
And teleportation locomotion is wonky.
sly elk
hey all, I need 3 more subscribers before youtube will let me make a channel URL.. can one or two of you help me out?
mighty carbon
Ok, subscribed
sly elk
thanks
mighty carbon
Np
I'll be getting this one, probably
I'd like to see how it feels being in the low poly cuboid world
full junco
why is everything about a rift so annoying to do with roomscale
I already knew I have to buy 10 meter usb extension cable to get to the second camera on the other side of the room, but I didn't expect the cable of the rift to be too short for roomscale
do really have to buy both a usb extension cable and a hdmi extension cable for the rift now and then have 2 annoying cables that make it more heavy?
its horrible design from oculus
spiral zephyr
lol what do the cables combined cost then?
full junco
@wicked oak thats less than 1 meter I think? definitely not enough
wicked oak
i do think the oculus cable is stupid short
usually for my playspace is enough, but it is stupid short
full junco
it really wouldn't cost them that much more to just use a cable with same length like vive
mighty carbon
long enough for average available room area
full junco
less doesn't really work
steamvr doesnt even let you continue the setup if you have less than 2x1.5
an average good area is probably 3x3 meters
sly elk
Yeah, im right on the edge of the steam VR minimum space. I need to move some furniture out of my office. Also oculus tracking get bad as you approach walls and are occluding the touch controllers
full junco
well I didnt test it too much yet but it seems to work quite fine even with only 2 cameras
I don't need it to be too perfect, only need it for making sure my game works fine, for everything else I can use my vive so thats fine
glossy agate
If they do that and get some decent controllers to go with it, that will be huge!
All the good games can go in front of the bigger audience.
full junco
yeah, I would probably try to port my game for PSVR then
good tracking is the only requirement, performance can always be worked on
glossy agate
Yeah. Would give a lot more people a reason to buy in. I would buy one.
full junco
wellI definitely wouldnt want to play with one, the GPU of a ps4 is still quite shitty compared to a 1080
glossy agate
But if its super convenient with a big player base for multiplayer I would be sitting in my living room instead of my home office more than I do.
full junco
yeah, people usually have way more space in their living room so good tracking solutions that support something like 5x5 meters definitely make a lot of sense for consoles
glossy agate
Yeah, my office is 10*12 ft but I have desk, telescope giant beanbag chair ect so Im still banging into shit, knocking all my military stuff off the walls haha.
full junco
lighthouse is the perfect tracking solution, sony and microsoft should both just use that
though I guess motors and lasers will always be more expensive than cameras
wintry escarp
new lighthouse is much cheaper isn't it
wicked oak
lighthouse is clearly the best right now
but it doesnt really scale
with cameras you can add things like object/gesture recognition and similar
lighthouse only does what it does, but it does so flawlessly
full junco
@wicked oak to get sub-mm precision on 5x5 meters you likely need crazy high res cameras with something like 8K though
wintry escarp
rift works ok, just needs 3 sensors really
wicked oak
what about both at the same time, like leap motion style camera + lighthouse
wintry escarp
whats the little round patch on the rift controllers for? the one that looks like they cancelled a button
doesn't seem to register touches
full junco
@wicked oak I don't think you need any object recognotion or gestures in VR
knuckles are pretty much the perfect controllers
full junco
well, with the current price of the vive no one buys it anyways, and LG probably can't compete with the rifts price too so they don't even want to release their headset. so valve probably has no idea how to make people actually buy knuckles. standalone not too many will buy it I think
wintry escarp
would be intresting to see up to date sales figures for rift
full junco
if steamvr headset manufacturers don't get any of the steam money, I don't see how they will ever be able to compete with the rift pricing since oculus can sell the rift at a loss without much issue
wintry escarp
I don't think theyre selling at a loss
wicked oak
as long as the price is logical like 100-150 dollars
a LOT of vive users will get knuckles
full junco
do knuckles work with old lighthouses?
full junco
well LG might have the issue that they can't compete with the rifts price
wicked oak
even if they used the newer sensors, the sensors have backwards compat
full junco
so either noticeably more display res or something like eye tracking
wicked oak
it will have more res
thats confirmed
but not that much more
and lenses and screen tech is super important
they say its a 1440p screen. The rift is 1200px verticall (as vive is)
so not that much of a difference
mighty carbon
making stuff for consoles is horrible experience, judging by what @wicked oak says here and by reading from other sources
wicked oak
but $
full junco
LG probably waits with their headset until they have some real advantage over the rift to justify a higher price
wicked oak
and support that actually answers to mails
and not having to support anything more than 1 hardware config
mighty carbon
don't have to support multiple configs on PC either
it's not early 90s
I guess if a team has a programmer who also skilled enough to work on UE4 codebase for PS4, then maybe it's not a big deal
for me personally it's a nightmare I wouldn't want to step into
wicked oak
after testing some stuff. the best way BY FAR of getting VR text is to not use text
put it into a texture, with proper mipmap settings
it aliases a lot less and the text looks great
on the downside, you need to do textures instead of just programable text
mighty carbon
but, what about localization ?
it would be royal pita to localize a tom of text if it's in the textures or 3D
tired tree
?
3D is no different if you make multiple fonts
you can get localized text still
textures...more of an issue
mighty carbon
how do you do 3D text? I thought it implies modeling it in 3D app
(words and sentences)
wicked oak
@mighty carbon as you wouldbe doing the 3d text as models, you just swap the models
any asset can be localized
textures or meshes
full junco
3d text as static models isnt nice
wicked oak
if you create your 3d text from a FText variable, then its much easier
mighty carbon
do you guys know if anything major coming in 4.18 for VR or gameplay ?
sly elk
i REALLY hope we get more forward rendering goodies or optimizations
The simple faked foviatged rendering nvidia showed off a while back looks great. I would love to be able to set more super sampling for just the center of the image
mighty carbon
I know that @full junco lurks on github, so I am hoping he can shed light on what's already in 4.18 branch
full junco
@mighty carbon epic is super slow with merging stuff, currently no new vr or rendering things are in master that aren't in 4.17
mighty carbon
ouch
something tells me that not much stuff will be coming for forward rendering or VR
mighty carbon
but 4.17 doesn't have much for VR rendering and such, does it ?
glossy agate
Didn't we just get forward in 15 or 16?
Gonna have to wait till robo recall 2 for the next major feature
mighty carbon
right, we did, but people keep saying it's missing some important features (like what?!) and optimizations (?)
sinful iris
Hello
mighty carbon
@tired tree @full junco is there really something missing in UE4 for VR currently ?
sinful iris
So
I just got Unreal
I'm in the VR template
The Motion Controller map
Where do I start?
Is there a good guide?
I have no idea what to do.
mighty carbon
@sinful iris do you know UE4 well enough where you can make a small game prototype ?
mighty carbon
then there you have your answer - learn UE4 first, then get back to VR
also there are books and youtube full of tutorials to get you going
sly elk
I have had a lot of comments on my video about the tracking being shaky. don't remember it being shaky when I recording it so im not sure if there was something going on with capturing VR + 4k video or if I was just super tired after doing many 15 minute assembly runs back to back. Is this normal for VR capture?
Wow, I did a terrible job writing that out.
@sinful iris do you have other gamdev experience? I don't think working from the VR template is really any harder than from the first person or third person template. You just need to start digging . Get stuck, work hard to figure out why, keep repeating that
sinful iris
@sly elk Sorry, went AFK. I have made basic mobile 2d games, so a little...
sly elk
I think you are just going to have to jump in and struggle for a while. Moving to 3d might throw you off a bit, a lot of us probably take some of those basics for granted. Start by watching every blueprint related video on the unreal engine channel and follow all of their tutorials.
the vr template blueprints are actually pretty simple and its all organized and named. You want to be looking at the BP_MotionController and MotionControllerPawn. If you already understand basics like variables and data types it should make sense fairly quickly.
glossy agate
@sly elk I have gotten those types of comments on my videos too. I think some of it has to do with when you are holding something long it has no real weight to it so just a tiny move of your hand gets really exaggerated towards the end of the thing moving. Also the capture is going down from 90 to 60 fps which reduces smoothness also.
uneven moon
Scenario:
- 2 VR pawn BPs, 2 game modes. Each corresponding with one.
- I override the game mode in my main menu to use the 2nd pawn I created. I drop that pawn into the level, and only that pawn.
Problem:
- When I use the first pawn that I originally created, it works fine.
- When I do what I described and use the 2nd, with the game mode using that 2nd, it doesn't work right.
The VR preview starts depending on where my viewport is and not where the pawn itself is.
Notes:
- If I drop the first pawn back in and remove the 2nd, it works fine. Even when the game mode specifies that the 2nd should be the default.
- If my project settings maps/modes is set to a default game mode for the 2nd, the 1st only works still... So no matter what, the first works, 2nd does not.
- Both pawns are set up to work exactly the same, one just doesn't have motion controllers (yet).
forest plover
When you use the gamemode, its gonna spawn the pawn unless you tell it to posess the one you placed in the level
uneven moon
Interesting, one sec
The first pawn is set to '0', should the 2nd be set to '1' then?
^ Inside the pawn
forest plover
nope, in VR your always player 0 because you can't do splitscreen with it and in multiplayer everybody is player 0 according to their computer
uneven moon
Okay, so both pawns are set to auto possess player 0
What do I do with the game mode?
Default pawn is set to 'Pawn_Menu', which is the 2nd one I mentioned.
forest plover
the gamemode is meant for gamemodes, if your not going to use it then don't worry about it. But putting both to posses player 0 isn't going to work because you can only control one pawn at a time
uneven moon
I need to control only the 2nd pawn which is called 'Menu_Pawn', on the main menu. Then, when I start the game, I want to control 'VR_Pawn' which is the default for the remainder of the game.
So how do I specify which level uses which of the pawns?
forest plover
Through code, either through Blueprints or C++ but you would tell the player controller to possess the pawn that you want to control
uneven moon
Ah, so in the Level BP for each level, I can possess the correct pawn at begin play?
As long as that pawn is in the level, ofc.
forest plover
Sure, if you want to go that route
uneven moon
Will the player notice anything strange or will it be instantaneous?
forest plover
Test it and find out
real needle
Is device type still "Invalid" for SteamVR pucks in 4.17?
I don't have a puck around to try with atm
uneven moon
Trying to get a persistent line trace coming out of my hand in VR but when I play the level, the line trace is on the floor where the pawn originated and not emitting from my hand (the 'LaserOut' scene component that defines the 'start' of the line trace is attached to my hand, however)
Even when I set the starting point to be my camera, it's on the floor where the camera originated e_e
real needle
@uneven moon Because you're running that once on begin play. The motioncontroller location will be 0,0,0 the moment the pawn is spawned
First tick is when it'll actually get a transform from the motioncontroller component
Put that on tick instead and set debug to each frame
You're seeing the same result putting it on the camera
slim raft
Anyone else sometimes get one Vive controller stuck with a blue light refusing to track properly?
Keep doing random things for an hour and then it eventually works properly for while
Then repeat
real needle
The blue light usually indicates that the controller is on but not connected to the HMD I believe, I have a pre so I can't test it. But turning one on without SteamVR should do that
pearl tangle
try switching it off and re pairing?
real needle
Yeah turning it off should do it. Hold it down for 8 sec or do it through SteamVR
pearl tangle
yep blue means no connection
frosty robin
Does anyone know why my VR Camera is spawning (and tracking) from a specific height instead of from the floor level? im using HTC Vive and using roomscale setup.
The tracking origin is set to Floor, and im not using any offsets to the Pawn at all. It feels like it's using eyeheight tracking as origin.
I've verified that the tracking origin is indeed set to floor!
real needle
@frosty robin Which pawn class are you using?
frosty robin
Whenever i restart the VR preview it seems to set the HMD location to the Floor origin. ( if i put the headset on the floor, then start the VR preview, i get a pretty okey result..
im using a regular pawn
real needle
Are you sure you're not setting "Set Tracking Origin" to Eye?
That's what it sounds like
So not a Character?
frosty robin
Nope, not character.. Parent is pawn
real needle
Kk just making sure
real needle
What is the actors location
frosty robin
doesnt matter, there is basicly no offset between my VR origin and my HMD
real needle
IE is it level to the ground in game
frosty robin
yeah Z = 0
real needle
WHat does your component hierarchy look like
real needle
Restart Unreal and SteamVR
frosty robin
yeah im doing that as we speak.. but we're getting the same problem on different computers
real needle
Try the VR-template motioncontroller pawn
frosty robin
yeah
Okay... Restarting the project and deleting saved and intermediate worked
so strange..
specially since both our computers had the same problem.. (with Different save / intermediate)

Guess nobody has the same problems with it that I do then...
Its a replacement controller I bought that came with a blue strap after one of the originals had its trackpad go gummy.
full junco
do you still have that one?
fixing the trackpad is easy, you can do that yourself, I also had to do that with mine
slim raft
Yep, tried throwing it against the wall like 8 times and still didn't fix the track pad
slim raft
I assume the rubber gasket is misaligned. It doesn't click properly.
Don't have the right size torx laying around and keep forgetting to buy it.
slim raft
No blue light problems with it though, unlike the replacement
full junco
you just have to buy that torx thing and then you can fix it
its not hard
you have to take the whole controller apart, but its also kinda fun
but a torx screwdriver is definitely cheaper than a new controller
slim raft
Frustrating that the replacement model never works like it should still
full junco
yeah, HTC is just really not doing stuff the way they should
I dont get why valve doesnt just build headsets themselve
if oculus can do it valve can do it too
mighty carbon
well, Oculus has no manufacturing plant for Rift.. So they heavily dependent on the vendors. HTC has it all, so it's quicker to build, fix and repair their HMDs.
tired tree
Valve already booted up manufacturing for steam controllers and likely knuckles as well
I think they just want to be the middle man instead for full HMDs

Anyone use light shafts in VR yet? Looks like there's a strange stereo glitch, very subtle, when I look to the side and not directly at the light source there seems to be a bit of a visual error
Like the stereo isn't quite accurate
Using a directional light (light shafts enabled) with an exponential height fog (volumetric on)
Feels like the left eye is affected slightly more than the right because it's closer to the direction of the light
glossy agate
Volumetric fog for me feels like a texture is just stuck to the screen. You find a way to make it work good?
full junco
@uneven moon light shafts are a screen space effect, you will always have different results for the different eyes on them
they still looks nice I think

the touch controller mesh from the engine content has a strange pivot point, it absolutely doesn't align with where it should be when just placed at 0/0/0 relative to the motion controller component
the rotation also seems to be off
is there a simple way to fix that?
@wicked oak did you recently mention something about touch controllers being different ingame than vive controllers?
wicked oak
@full junco yes, they are angled
around 30 degrees
its specially obvios if you align a sword
if you align a sword with the angle of the Vive controller, it will be around 30 degrees rotated for the oculus, and feel really off
tired tree
You hold them differently
full junco
@wicked oak @tired tree its not just 30 degree angled, and its also not just the way I hold them. when I click the steamvr button I see my game in the background while also seeing the correct representation in the steamvr overlay, and the controller in my game is at a wrong location and also at a wrong rotation in all 3 axes I think
wicked oak
in my tests the mesh is perfectly aligned, if you use the meshes that are in the engine folder
for both vive and oculus
wicked oak
for psvr there is a default model with the ps4 sdk, importing it and rotating it 90 degrees (becouse reference axis) makes it also be perfectly aligned
thats weird
maybe steamVR is adding some offset on its own
wich makes sense
full junco
does it?
tired tree
wouldn't know about offsets, I load the meshes from the SteamVR API directy
full junco
@tired tree is the steamvr touch controller mesh having the same pivot location and rotation like the mesh in the engine?
tired tree
yeah
think they pulled it from steamvr in the first place
they are adding in mesh loading for steamVR btw, its mostly complete in the back end right now in 4.17
just no blueprint interfacing yet
full junco
well I don't really want to load it because I want to be able to edit it to show the user stuff directly on it
if the pivot transform of the one steamvr gives you is the same like the one the engine has, I shouldnt see any issue though
full junco
yeah for oculus touch
and why is the rift so often just shutting off and no longer displaying any image until I restart the PC or replug the rift USB cable...
tired tree
proximity sensor?
full junco
it stays black even when I wear it
I guess it doesnt like the usb port it is in
all my usb 3 ports like to shut off for a few seconds every minute or so
the mesh of the touch controller in the engine actually looks wrong too
the thumbstick looks way different in the real controller
the mesh steam has looks correct (the thumbstick)
full junco
ah, good it to work with the mesh from steamvr 😄
that one has the correct pivot
it also has the correct left/right version of the controller, UE4 only has 1 so obviously that can't be correct for both hands
wintry escarp
using a direct hdmi port or dp adapter?
forest plover
I have not seen that issue with the rift shutting off every few minutes, only when I take the headset off like it normally should. It might be a problem with the USB ports not supplying enough power or using USB 2.0 instead of 3.0 or something...
full junco
@wintry escarp I use direct HDMI
sturdy coral
oculus usb stuff is fucked, every time I boot I get a million disconnects/reconnects

I also very often hear the windows sounds that says usb device connected/disconnected

"very often" meaning once every 20 minutes or so
wicked oak
nor in my main PC or my laptop
sturdy coral
I have their recommended USB card too
wicked oak
what is annoying as fuck is the oculus launcher popping up constantly
full junco
its annoying that the oculus app can't disappear in tray
also, UE4 often doesn't recognize the touch controllers for some reason, so then I need to restart UE4 to be able to use the controllers
sturdy coral
anyone going to oculus connect? I just got accepted but I'm not sure this year, it is only 2 days this time
one whole day will likely be product announcements and PR stuff, so it feels like it won't be much of a dev conference
wicked oak
free hardware for devs is a very probable thing @sturdy coral
honestly i didnt even apply to it. I dont have the resources to go to the other side of the world just for the hell of it
sturdy coral
last two years hasn't had free hardware (other than headphones) but yeah maybe this year since they might be announcing that standalone thing
if it is just the 3-dof one that's a bust though 😛
they did give out a gear vr holder at connect 2
wicked oak
3dof standalone is still interesting
it would be a souped up GearVR, but cheaper
(cheaper as a whole of course)
wintry escarp
did something on the rift screens, I thought you were supposed to avoid pure black but it looks much better to me than just above it, that introduces noise
did something change
wicked oak
i think there is no true black on the rift screen
and thats by the driver itself
PSVR also does the same thing. To avoid dark bleeding
becouse if a pixel is too dark, then it takes time to "wake up"
it was a common thing on the DK2
wintry escarp
ok, thanks
sturdy coral
yeah, I don't think there is any true black on vive either, the fresnel glare mostly hides it on both of them though

[DAYDREAM APP] Hello guys. I hope everyone is well.

Has anyone else experienced this?
sly elk
is there a way to do smoothing on motion controllers?I only want it for recording videos. In game in sure that would be horrible. I would love to stop getting comments about shaky hands.
wicked oak
dont do a direct attachment
and do a lerp transform on the "smoothed component" so it lerps towards the transform on the motion controller component
i do that myself in multiplayer, to smoothly interpolate the other player hands
sly elk
ideally I want it for the hands, not just the pickups
for actual in game I want to some kind of rotation damping based on mass so that my heavy objects have some sense of weight
wicked oak
that usually feels bad, at least from my tests
i never like when the hands are absolutely perfect attachment with zero latency
but yeah you could do that. Robo recall uses spring interpolation for that stuff

looks like a good solution, is based on depth so it won't work with translucency, but translucency doesn't usually have hard edges anyway so if the sharpen filter applies over it it shouldn't matter too much

hm you guys have a good example page to see what can affect Shader Complexity poorly for Forward Rendering?

Shader complexity problems are mostly the same in forward or deferred, except dynamic lights are generally much more expensive. Also, quad overdraw is more expensive in forward than it would be deferred if you have MSAA enabled.

the old Deathwave, once it stopped having sales and i abandoned it
got me around 500 dollars from th bundle
tanked my reviews
real needle
which bundle company was it
glossy agate
I heard bundle was good for regular PC games, but it sounds like it goes different for VR. Probably because people buy the PC bundle for like 2 games and ignore the other included games so the dev just gets the money and less chance of a review haha.
mighty carbon
no, it was never good
not unless you were friends with bundle holders and got a bigger cut

Am I the only one that completely disables AA for VR, or am I alone in that?
wicked oak
yes
people use MSAA, temporal, or FXAA if there is no choice
Temporal is blurry, but smooth. Msaa is a huge resource hog and needs forward render,but is glorious
FXAA is shity, but better than no AA
dawn cipher
So what's the downsides to FXAA, someone was asking me on Twitter earlier today @wicked oak
My understanding is everything becomes kind of blurry?
slim raft
I hate the forward render
It always seems like every effect I use is incompatible with it.
real needle
there are reasons why it is quicker...
slim raft
I actually prefer no AA to FXAA in VR
You have to make text huge to read it if you have FXAA on in VR
With how low-res hmd screens are, I prefer the sharpness of no AA anyway
dawn cipher
Yeah there's many effects which are only enabled by the deferred part of the deferred renderer
And the Forward renderer is kinda experimental because it's just the one Oculus helped build?
I'm using it because I want to have a real spectator screen which means I need the performance gains
real needle
the performance gains are substantial. I was frustrated to lose light shafts, but the performance (and sharpness) increases more than make up for anything lost. you can get back whatever vibe you were going with by alternative methods (materials, etc)
slim raft
I can't remember, does custom depth work in the forward renderer?
real needle
in what sense
if you're thinking of the fog stuff, you can still use exponential height fog
dawn cipher
@slim raft I think so. I don't see why not
real needle
gbuffer stuff is out
slim raft
Hmmm... Trying to remember what the deal breaker was for me last time I tried it...
dawn cipher
You're not wrong though, there's definitely unsupported things. Wasn't having much luck with deferred decals last time I checked, which is kind of obvious given their name
real needle
yeah decals are out as well (I agree, seems odd)
the readme on the GitHub has a pretty decent list of what works. I found that if they didn't say it worked, it doesn't work
dawn cipher
@real needle it's not odd - deferred decals need the gbuffer :p
I don't know why it sort of works, I ended up with a washed out image that didn't play by the correct projection rules

Custom depth works fine in forward

I still have the issue with left / right controllers randomly being picked by UE4 with steamvr so it's sometimes wrong. super annoying.
for some reason to code for setting the controller sides in ue4 is quite complex
so not easy to fix
sturdy coral
one of their patches was they weren't completely checking that the tracked device was a controller
and if it didn't have a hand they defaulted it to left or right or something
slim raft
Still does that
sturdy coral
and then when it actually got a hand, they would look and see left is already in use, force this one to right even though the API says left
slim raft
You have to make sure to turn on a tracker after the controllers
full junco
what is a tracked device if not a controller? I don't have any trackers
sturdy coral
yeah, I didn't know if the headset might be interfering with that too, since it is a tracked device
slim raft
That's separate from it assigning the controllers to the wrong hands.
sturdy coral
I think even the base stations show up in the tracked device list
but I don't know if there is a guaranteed order
full junco
if openvr says something is left then ue4 should respect that no matter what
sturdy coral
I just saw a diff addressing that I think with 4.17 and didn't look into it too closely
slim raft
My tracker is consistently 5 if I turn it on after the controllers, but if I turn it on first then it gets a rando. I assume they are just listed in the order they begin tracking, so the first two are probably the base stations
sturdy coral
they still don't get chaperone bounds the right way
if you start the game while the HMD and controllers can't see any base stations
they never get the right bounds
err the playspace area, not the chaperone bounds
full junco
I usually start the game with hmd and controllers all not tracked
sturdy coral
I've got a pull request to fix that, but I probably need to refactor it because I changed the api and didn't strictly need to
yeah when I didn't have tracking at my desk it started like that all the time for me
slim raft
I get weird bugs if I have steam vr already running instead of letting it start with UE4
Sometimes I fly off into the abyss
I assume NaNs in the tracking data somewhere
Haven't been able to track it down though
sturdy coral
I've had occasional crashes with a trackback saying invalid quaternions in the motion controllers or something, but not in a long time
full junco
the left right issue is way more annoying when you use a rift since you can't just switch controllers
sturdy coral
oh yeah, that's totally broken if it happens there
slim raft
I didn't know it also happened with the Rift
full junco
it happens 50% of all time
I always just have to restart when that happens
obviously I can't release a game like that
sturdy coral
yeah you want to do anything you can to avoid a negative review
full junco
if I can't fix it I will have to implement a quick "press trigger on left controller" check when the game starts and the reattach all meshes and stuff and adjust logic so that its on the correct controller
tired tree
VR Objects shouldn't "fly away" anymore.......is it something you are running off of position that is reading invalid locations and adjusting incorrectly?
currently tracking just stalls if its a bad tracked location
slim raft
Yeah, my character extracts the motion data from the tracked objects and applies it as locomotion via a custom movement component
tired tree
oh that....I worked with you with Yore for awhile, though I recognized the name
you can check for valid tracked position
slim raft
Well, thing is it does seem to have valid tracking as the ik on my character still works
tired tree
I have a character that does the same thing as a basic alternative, it doesn't have an issue on tracking loss, gotta be something weird going on
is it rift only?
slim raft
I don't have a rift
Could be a bug in my mathematics post getting the tracker's data, but I can't think of anywhere I perform an operation on it that would result in a NaN
Just know that when the bugs happen my velocity logs as NaN
Sometimes I start flying upward and flip upside down
But that goes away if I delete saved and intermediate folders
So I assume that is normal UE4 weirdness
full junco
I never had anything fly away
slim raft
I've been having a bug lately where things I do PIE affect the level file somehow, so it could also relate to that
Like, spawn an object during PIE and then when I exit and start PIE again I notice its still there
full junco
this is how UE4 assigns the controller: https://puu.sh/xgb8n/1616f2a85c.png
on this occasion, the result was correct, so left/right was set correctly
dawn cipher
The Unity SDK does some more complicated detection logic (checks for all controllers, checks which one is further left/right relative to the forward facing of the headset)
But more importantly it has a function to redo detection so you can just call your game to update it at a more logical time, ie: after the headset has been put on or such
The Unity SteamVR*
full junco
why would you ever check if controllers are further left/right relative to the HMD?
that can always give the wrong result
dawn cipher
That's how they detect left vs right controller
full junco
but that would give wrong results way too often
dawn cipher
They assume that if you have two controllers infront of a headset that they're in roughly left to right order
Such as...?
slim raft
Only when your arms are crossed
dawn cipher
And who crosses their arms when picking up the controllers
full junco
when I'm taking off my headset I dont really always put it in between the controllers or something like that
slim raft
Why would that matter?
full junco
and with the rift, the left controller has to be hold in the left hand, you cant hold it with the right hand. if the game detects left as right, you can't use it
the engine has to depend on what the sdk tells it, guessing depending on location of the controller just can give wrong results
I just restarted UE4 4 times and the controller side was actually always correct, how annoying, just when I want to look at what the debug says its always correct. maybe it depends on when steamvr was started too and not just on UE4
dawn cipher
@full junco "the leftmost relative to the headset" - it doesn't require the controller to physically be to the left of the headset, it just uses the forward direction of the headset to determine which orientation left and right are from.
I imagine the SteamVR plugin works differently for Oculus since they do have non-interchangeable controllers.
I do notice that Unreal gets confused in the editor about if controllers are on or not (ie: on and recognized by SteamVR but not by Unreal) but it doesn't seem to happen in builds so
full junco
that can still give wrong results though if I just switch the sides of the controlers
it is primarly an issue with oculus controllers
vive controllers you can just switch in your hands so its not much of an issue if the game picks the wrong one
but with oculus the game has to be correct in 100% of all cases
so guessing based on which side the controller physically is when the game starts is no option there
tired tree
its anoyying with steam overlays too since the input is one hand at a time and based off of the steamVR assignments
full junco
you mean the keyboard for example?
full junco
for some reason I can't actually get UE4 to pick wrong controller sides now
I got it all the time when I wanted to test stuff in my game and always had to restart then to be able to use my game
and now when I want it to be wrong it never is
tired tree
are you on 4.17?
full junco
no, 4.15
4.15 had a PR merged that "fixed" the wrong controller sides actually
so thats when the issue was "fixed"
tired tree
was going to say, they made changes to it in 4.17
full junco
maybe its actually only happening when controllers are fully turned off when UE4 initializes them
how do I turn off a touch controller?
I tried only having left tracking when UE4 initializes controllers, only having right tracking, having none tracking, but its always correct with those currently, so they have to be turned off for the issue to appear I guess
ok, its impossible to turn them off, but they have a great feature that I forgot about!
you can just remove the battery 😄
dawn cipher
@full junco the dev touches used to do that if you shook them too hard lol
full junco
do what? turn off?
dawn cipher
Yeah
full junco
the battery live of the touch controllers is crazy good btw, I used some old rechargable AA batteries that I didnt use for a few years in them, and the oculus software still tells me the battery is full after many days of heavy use
ah, I finally got it to initialize the controller to the wrong side!
I turned off the right controller, and then the left one is set to the right (wrong) role by UE4
I guess that behavior actually makes sense with having the vive controllers in mind
some vive games only need one controller, and that will be the right one, so if you only have one controller you actually want it to be seen as the right one
makes sense, right?
so its actually not random
@tired tree do you think they would actually "fix" that?
tired tree
in the motion controllers they added a check for if only one controller
for gearvr controllers and the like
an "any hand" setting
it auto assins right i think
assigns
full junco
hm, ok
thats how it looks like when UE4 sets the left controller as the right controller
I don't get why GetControllerRoleForTrackedDeviceIndex() actually always returns Invalid
slim raft
"pickign"
full junco
it should not return invalid, right?
tired tree
no it shouldn't, but it was all sorts of screwed up in 4.15 due to a SteamVR update
slim raft
Probably means whatever coder they had write that part had to do it in a hurry
tired tree
thats when the vive trackers broke in ue4 too
slim raft
Vive trackers are broke ?
tired tree
vive trackers are supposed to be run through std motion controller components in ue4
full junco
@tired tree so you say the SDK thats used in 4.15 doesn't work correctly with recent steamvr versions?
slim raft
Looks over at tracker I've been using all day O_O
oh
Yeah, I've been using get tracked whatever by index
tired tree
they broke due to a sdk update and people were manually getting position and I had a custom component until they were fixed
you can get the tracked locaiton, but some uses need the late update as well
full junco
I already updated the openvr sdk to 1.0.4, if updating the sdk would make GetControllerRoleForTrackedDeviceIndex() return correct values I would do that, but do you really think thats the case @tired tree ?
slim raft
The late update would be nice, but isn't as critical for a belt as the it is for hands
tired tree
its not the case
slim raft
Need to open GetControllerRoleForTrackedDeviceIndex() and take a look
tired tree
they had to change the steamvr plugin
full junco
@slim raft you can't "open" it, the openvr source is not public
tired tree
I use trackers for more than body parts, I retained the late updates for using them to hold things
slim raft
Well, then there is no way to know if that function will even actually work without trial and error
tired tree
thats note entirely true, you can run it through a debugger, buts its a hassle
full junco
@tired tree what do you mean with "change the steamvr plugin"? the issue is that the openvr call GetControllerRoleForTrackedDeviceIndex() returns an incorrect value it seems
tired tree
i wasn't talking about that
dunno on that one
you are sending a correct index to it?
full junco
the only thing that can improve what GetControllerRoleForTrackedDeviceIndex() returns is updating the sdk I think
I dont know if its using the correct index, I just assume its correct
if it wouldnt use the index of a controller, the tracking for controllers would be wrong, right?
slim raft
So the source isn't in this repo? https://github.com/ValveSoftware/openvr
full junco
@slim raft yeah, its not
slim raft
that sucks
dawn cipher
I mean, the Unity3D implementation of hte OpenVR API doesn't have htis problem iirc?
You can probably ignore the role for a device index and calculate your own
full junco
how "calculate"?
I cant calculate what it is, only the sdk knows it
I will test if the function returns correct roles in 4.17, if yes, that means its an SDK issue I think
dawn cipher
It looks like they no longer use their logic for determining left vs right in-engine and instead just get it from the SDK using GetTrackedDeviceIndexForControllerRole
full junco
I think in 4.17 they removed the debug log that printed out the result of GetTrackedDeviceIndexForControllerRole
ah no, I forgot to disable the oculus sdk so steamvr stuff didnt run
even in 4.17 it still says LogSteamVRController: Controller role for device 3 is 0 (invalid=0, left=1, right=2).
so GetTrackedDeviceIndexForControllerRole still returns invalid
I find it hard to believe that openvr is broken
@tired tree to be sure it uses the correct index, I printed out the result from the function for all existin device indices, and it seems UE4 actually runs the code every tick, this is the result: https://puu.sh/xgdxo/dda24653f6.png
its strange that it says device 3 is left there, which is correct
ok, it actually is 0, but once I press any button on the controller, it is seen correctly as 1
so when never any button on the controllers was pressed after UE4 launched, it will see the controllers as "invalid". only after you pressed any button, the controllers are recognized correctly
UE4 saves what it sees on the first tick though and ignores anything that comes later, so it will stay incorrect
moving the controller for a few seconds also is enough for GetTrackedDeviceIndexForControllerRole() to return the correct value
I think it might be possible to fix this with forcing UE4 to skip initializing any controllers that return a state of Invalid and wait until they return some valid state
I will try that
looks quite good I think
seems to work very well
full junco
thats the whole fix: https://puu.sh/xgfUS/f90229752b.png
UE4 ignores the controller until it can report what it is, works perfectly, at least I didnt notice any negative effect

Hey guys, quick question: anyone know how UPrimitiveComponent::IsOverlappingComponent() actually works? I'm trying to access it via the IsOverlappingComponent Node and it's always returning false even when I have two overlapping components (from two different actors) that both have Generate Overlap Events enabled. Any thoughts on what I may have missed?
Reason I'm posting here is that I'm trying to check if a motion controller is overlapping with a capsule collider
noble charm
Did you make sure the collision channels are set to overlap each other
white fern
Yep:
First one is the motion Controller Component
Second is my capsule collider
noble charm
Are you calling it in tick?
Are you sure the components are actually overlapping when it's called
tired tree
@full junco so its not detecting "sleeping" controllers then?
wicked oak
overlap events do not work well on motion controller components that have the low latency mode
at least last time i checked (caused me a headache with some sword stuff)
slim raft
Your screenshot says they are set to query only
Try collision enabled instead and see if that helps
distant stratus
hello! does anyone knows how to play a mp4 movie as loading screen in vr?
tired tree
low latency is render thread only, the actual "game" representation of the object is a half frame or so behind where it is visually
with fast movements that can get to be pretty damn far behind
spiral zephyr
got my wrist-controller working, very proud 😃 https://www.youtube.com/watch?v=b0k_hccOlps
Usind motioncontroller template, spawning wrist-panel inside motioncontroller_bp, and updating position just before doing teleport updates on tick. It's been working sweet so far.

has anyone used planar reflections with a capturecomponent / spectator screen?
mighty carbon
Has anyone used gameDNA's Google Analytics plugin in their VR app ?
@wicked oak I recall you used it, right ?
full junco
@tired tree I'm not fully sure it it's "sleeping", but it probably is, yeah
mighty carbon
@wicked oak what do I need to set up in the Google Analytics dashboard (I already got account for an app instead of website and got tracking ID) and where/what BP nodes do I add to get basic tracking data (region, language, number of users/new users, etc.) ?
wicked oak
region lenguage/number etc is automatic
there are events you can use like "record googl,e event" and other stuff
im not using it too well, but it gives me basic data
mighty carbon
@wicked oak So do I need to do anything special in the dashboard or all i need is tracking ID ?
