NewRotation.RotateVector(CameraRelativeLocation) - OriginalRotation.RotateVector(CameraRelativeLocation)
apply that as a positional delta
analog topaz
now the hmd height is broken :/
i asked about something got distracted by something else, which gave me another issue to troubleshoot 😄
uneven moon
How are you setting the HMD height to begin with?
This is 4.16, I believe 4.17 has new/different names for the HMDs
At beginplay, inside your pawn ^
uneven moon
What's happening with your height now?
analog topaz
it starts at the capsul height
uneven moon
At play or after you make a rotation?
analog topaz
i haven't added ur rotation yet
t
the camera starts at top
when am sitting when i stand up it goes even height
higher
uneven moon
Did you change collision settings or anything on anything?
analog topaz
it happened cuz i changed the scene root to vr orgin and didn't use undo to undo
i manually sert back everything
uneven moon
ah okay, all good?
analog topaz
no it is broken since then 😄
i have the camera position in the bp at -88
capsul halfheight is 88
i spawn at height 176 cm while sitting
when i stand up i go around 230 cm, ( tested with a bsp box)
uneven moon
You shouldn't alter your camera's height manually
Leave it at 0, 0, 0
And allow the tracking origin set to determine its height
uneven moon
Yes but I'm not sure if it's an off-set from 0, 0, 0 or if it overrides the camera's location completely
I'm assuming 0, 0, 0 is the floor level
That it checks for
uneven moon
Hard to say without looking at the project entirely
If you have TeamViewer I can take a look that way
analog topaz
going to pm u
uneven moon
ok
tired tree
camera overrides its own height automatically
the vrroot is what defines the starting location
uneven moon
you could optimize it
analog topaz
i don't think so
uneven moon
static lighting, disable shadows where you can, minimal reflections
pretty much everything in there is reflective to some extent
analog topaz
@uneven moon savior of the day
😄
why whenever i hti an object too hard it flies away out of the blocks around it ?
movable physics simulating object
uneven moon
increase weight
analog topaz
for some reason i thought decreasing weight gonna work better
but increasing it made it better gonna increase more till it works fine
thx sir!
@uneven moon any other ways? cuz it doesn't seeem to fix it
analog topaz
sometimes by just letting go of it
sometimes by trying to put it on a table
it shoots up like a cnnon going through the ceiling
uneven moon
if you let it go while inside of another mesh, it will jump
what happens if you let it go in mid-air?
analog topaz
how to reduce that jump effect?
if i throw it in mid air sometimes it disappear even if it didn't collide with anythign else
some other times it colide normaly
uneven moon
it's colliding with something invisible, possibly your capsule if it's not centered with your camera
as for the jump effect
not that I know of
analog topaz
i have capsul visible, and i have it to ignore colliding with physical actors
uneven moon
I think you could just check for that and move it to the surface if it happens
oh
any other invisible objects?
analog topaz
nope i have collisions hown
uneven moon
what object are you using and what level is it in? Templates?
analog topaz
yes but i changed the meshs
not the template level
but the template blueprint for grap
objects but i changed cubes to shoes and bags
uneven moon
ah okay so,
do your meshes have collisions? if they were generated by UE4 by default then they likely won't be accurate and will be something like a cube, maybe. which would explain the invisible collision
open up your mesh and click on collisions > show simple
see if the collision bounds are accurately mapped
if not, delete the one that's there
and create a new one, something more complex
that will take on the shape of your mesh
that should fix one problem
uneven moon
are you picking up objects with a bag?
analog topaz
no the bag is one of the objects iam pickign with my hand
analog topaz
yes sometimes not always
uneven moon
what about your hand? what mesh?
analog topaz
but hands has no collision while am not griping
i mean my hand can go through them unless i click the tricker
trigger
tired tree
when they ar ephysics enabled already?
tired tree
and you don't turn collision on during the grip? many do that
analog topaz
not sure, but the cubes in the template map works fine
tired tree
are there multiple components on the object
analog topaz
what do u mean ?
tired tree
like two meshes on the same actor
analog topaz
no
each acor has it's own mesh
it's a mesh issue cuz i replaced them with other meshes
they worked fine
mighty carbon
is that a virtual store ?
analog topaz
yep
tired tree
lol
analog topaz
no it's so far away from that
i just added ingame browser widget thing
to redirect to there whenever u u click it
mighty carbon
well, the thing is that IAP isn't implemented in UE4.. So it's odd that you haven't gotten important part working first 😃
analog topaz
but it's only for viewing nothing else
and that web browser thing is for the fun of it
simplfied box collision fixed it
mighty carbon
oh, I see.. Cool 😃
analog topaz
tha'ts what u get for free 😄
sly elk
@analog topaz I switched all my grabs over to traces and got rid of the collision meshes. I found having collision on the hands was likely to interfere with other collision based gameplay functionality.
analog topaz
yes apparently it's not best practice, but so far simple collision fixed the issue for me,
currently working on issue number #9000 😄
tired tree
@sly elk I always ran traces for grabs, but I added a fallback overlap because the trace will fail if the hand is inside of an object entirely
uneven moon
I'm trying to rotate my motion controller itself but it keeps defaulting its rotation, any reason I can't change it?
tired tree
yeah..the motion controllers rotate themselves each tick, why do you want to manually change it
sly elk
i haven't run into that issue of the trace failing. But I start my trace right around the root of the wrist
tired tree
I run base of palm forward
but if they are wrist deep into an object that trace would fail
uneven moon
having a problem with it changing the rotation of my hand mesh at one point but I figured out how to fix it just now
analog topaz
nice, i was googling that t ohelp out 😄
hey @uneven moon that's how it worked for me looks almost exactly like echo arena
the rotation thing
tired tree
@analog topaz did you want set increments or it to scale based on thumb position?
because that one can end up rotating only like 1 degreee
or zero
glossy agate
That OVR lip sync sounds cool. Rec room avatars on steroids
mighty carbon
if only we could feed wav files to it for NPCs to have proper lip-sync
tired tree
far from proper...
regardless the lip sync SDK COULD be passed recorded audio
if you really wanted to
glossy agate
Probably easier to use the existing solutions for now. I know there are a few. Maybe even one for Blender
mighty carbon
nah, I'd not want to animate lips in Blender and then mess with it in UE4.. Procedural (via Avatars SDK) is a way to go, even if it's not perfect.
tired tree
you still need blend targets
analog topaz
yes i used the thumbstick cuz i wanted to rotate left and right, so i take the value from the axis multiply it with the floatxfloat
and when i am not using the thumbstic the value is 0 so there would be no rotation @tired tree
cuz when i used it without that it kept rotation endlessly
glossy agate
Yeah its just for the blend shapes, but maya plugins like voice-o-matic or whatever will blend acording to the audio track for you.
Alvo looks cool, but pretty much all the anims are keyed in the trailer, not user directed. Gotta see how it actually looks.
tired tree
@analog topaz you are trying to snap turn though, right now if it is an axis value of like 0.5 you only turn 10 units
analog topaz
oh do u mean i can make a stable number out of this axis?
tired tree
you can take that axis value, get Sign of it and multiply by the angle you want to turn
analog topaz
liek everytime i click it it will give me a certain value
or the minus of this value depening on which direction i pull the thumbstic?
tired tree
yeah, get sign of it
will return -1 or 1
and ignore the 0.0 - 1.0
you can dead zone by branching axis < deadzone value
so it won't do it unless the stick is moved more than a bit over
analog topaz
ok i will try that
can't tell the differrence when i test
is that how to set it ? @tired tree
tired tree
no, branch off of the axis > deadzone
on true, get sign of the axis and multiply it by that turn amount
oh, have to ABS the axis before the branch too
also you wouldn't notice a difference if you are pushing it all the way down, it is if you hold it only a little down that you should notice
analog topaz
can't get it to work, but it is not needed atm, i mean it's nic eto turn slower if u won't pull all the way back 😄 i gonna read abit about abs and other nodes before i try to apply them on something
thanks for showign me teh way tho
mighty carbon
are you not using VR Expansion plugin @analog topaz ?
white fern
Hey guys, working on one VR project and I'm using the VR template. What Is driving me insane is that for some reason grabbing (attaching) an object in the right hand works fine, but grabbing an object with the left greatly changes the orientation of the object, even though in both cases the object is supposed to be snapping to a socket position.
In the VR template the only difference b/t the two hands is the Hand enum, which causes the left hand mesh to be world scaled to x:1 y:1 z:-1 to flip it on it's local axis. How does this affect skeletal mesh sockets?
analog topaz
@mighty carbon nope
tulip surge
Yey kinda looks ok, just so desaturated because its a screenshot from the monitor, ingame doesnt work for me

Can't get around using a 2d scene capture for a VR sniper scope, even with a low res of 250x250 the FPS drops on lower-end systems I had some guys test
Only solution is to use skylight in a shadowless game
How do other games get around this? Onward, one example
glossy agate
@raven halo cool use of the pickup mechanic
glossy agate
@wicked oak you just lerp a particle along the trace line or using actual projectiles?
wicked oak
its a static mesh
with a fancy material
for the projectile
the muzzle is a mesh based particle effect (so its fully 3d)
and the impact hit is gpu sparks
im happy with how it looks, but the muzzle is still possible to improve a lot
the projectile and impact hit are fine as that
maybe i port them to DWVR
as they look quite good
@glossy agate on the muzzle, im open for suggestions
most muzzle fx are some kind of smoke simulation wich is 2d
glossy agate
Right on. Isn't that a pretty big perf hit to use actual projectiles, or just too low of a number to matter?
wicked oak
this new system is actually more optimal than the one in DWVR
DWVR can get to 100 CONCURRENT projectiles at once per frame
and ive tested it with even more intense stuf
if there is truly an issue with it
then i can make the projectile mesh be an instanced mesh
and use 1 mesh for all the projectiles of a given type
glossy agate
I have tried 2d and 3D muzzle flash. The 3D ones I have are ugly though like white cones in VR
Oh cool. 100 concurrent is a lot
wicked oak
the one i have in that video is a warped cylinder with a fire-ish material
the particle effect spawns a bunch of them and fades them
glossy agate
Man I need to work on my game this weekend but all these good fall games are coming out distracting me and making me feel guilty haha
Anyone else here tried fortnite? I played it to see if they had anything interesting in there hoping I could copy VOIP if they opened up the modding system, but the game has no VOIP haha. Super hard to play squads like that.
wintry escarp
do you pool proectiles or make and kill them as needed?
wintry escarp
I was hoping c++ would avoid GC hiccups
wicked oak
thats ue4 stuff
ue4 hates the hell out of you spawn/deleteing actors constantly
stresses the gc too much
full junco
even without gc, spawning stuff is expensive and shouldn't be done often if it's not absolutely needed
mighty carbon
Still can't find any tutorials about objects pool
wicked oak
becouse its a generic programming thing
@mighty carbon the idea is very, very simple
you dont create and delete
you reuse
instead of spawning a projetile and then destroying it
you ask your pool object for a projectile
if there are "free" projectiles, then it gives you one
if there arent, it creates a new projectile and adds it to the pool
when a projectile gets deleted, it doesnt
it gets deactivated
and sleeps
mighty carbon
So I have an array with object references, where I spawn an object once and fill the array with its references ?
wicked oak
and when you ask for more projectiles, the system just gives you one of the deactivated ones
yes
no, you dont spawn once
first of all, your projectiles should have "activate" and "deactivate" logic
the pool system just creates an array of projectiles
and when a projectile is "destroyed", it doesnt really get destroyed
it gets deactivated
when you need to shoot a projectile, then you grab a deactivated projectile from the pool and reactivate it
essentially reusing it constantly
mighty carbon
Still over my head, sorry
wicked oak
of course, if you can have 20 projectiles flying at a time, the pool will be 20 projectiles
mine gets to around 70
glossy agate
@mighty carbon there is a marketplace plugin that does it for like $4 I think. Pretty cool because it runs tons of stuff for cheap
wicked oak
yeah its a good starting point
but it wont make your stuff work
you will still need to be careful that your activation/deactivation functions work properly
and that is the trickyest part
mighty carbon
Yeah, I was going to get it, but always see people complaining about things
wicked oak
becouse casuasl
making your own pool is trivial, in fact my projectile pool code is like 20 lines
glossy agate
https://www.unrealengine.com/marketplace/object-pool-plugin actually $10. Was like $5 on sale I guess
wicked oak
essentially it just has a "get projectile" function
the function searches the array of current projectiles, and returns one
wicked oak
literally all it is
the FProjectilePool is a struct that contains a projectile class and a AProjectile array
just so i have one pool array per projectile class
but you can have a single one for all projectiles just fine
jsut with a tiny change
little nacelle
Hello there! I have a question.
Is it better, to save performance, to have a big 4K atlas that stores like 10 objects' textures, or is it better to have a 256/512 texture map for each object? (and so 10 different amterials)
wicked oak
1 atlas
every time
the only exception is if you dont use all the atlas at once
imagine in level A you only use 5 of the 10 objects, and in level B 3 objects
then you are wasting space in a fairly stupid way
but if you DO use the atlas, then its a net gain
little nacelle
@wicked oak okay thanks! I was wondering if 4K is not too heavy to draw? Is it just called once, when the game loads and then keep it in memory?
wicked oak
the gpu doesnt care that much
and mipmaps exist
i mean, its a chunk of memory
1 chunk of size 4, 4 chunks of size 1, memory use is the same
little nacelle
okay good, that helps me. Also, how many polygons viewed at one time would you allow? is 2 000 000 a lot? I didn't make so much of tests so far.
wicked oak
depends
just think about it, a 1080p screen has 2 million pixels
at 2 million triangles, you are rendering 1 triangle per pixel
you can guess thats pretty damn extreme
im doing vr wich is worse
personally i aim for somewhere beetween 700k and 1 million
with about a thousand drawcalls max
little nacelle
yeah that sounds so logic. Okay, I have now a better idea about all that. Thanks again 🙂
tired tree
@mighty carbon it doesn't even have to be c++
a pool isnt' going to perform the getting part too much faster in c++ and if you initialize it with a few on construction it won't have to do the create too many times
its just an array of something, when its lifetime ends you store it inactive, and re-activiate when you need a new one
mighty carbon
But, do I need to spawn 100 projectiles on level start or do I need to spawn one and add it 100 times to the array?
tired tree
it would be 100
but no need to do that many
make a small buffer and if it overflows that you create a new one and add to it
if you are unsure if there will ever be a projectile of that type do what blanco is doing and handle it like the overflow case always
quaint loom
Confused as to what the projectile pool is meant to do though. a) Keep track such that only 100 projectiles can be spawned at any given time b) easier access to ref|location of objects for overlap detection c) etc? If it's # of projectiles on screen at once could also change the flight speed, despawn time, fire-rate accordingly for cpu&gpu considerations
perhaps if the intended issue|goal was known it would be clearer
ah I see, ty @wicked oak for posts above . Makes sense to re-use in activate/deactivate & relocate projectiles instead of destroying and spawning in new ones.
digital marlin
@wicked oak what do you use for movement? Gamepad?
wicked oak
@digital marlin just the vr controllers
this might be my next game, but its still not sure
im testing several different interesting mechanics that i might even backport to DWVR
digital marlin
Oh so you're using locomotion?
wicked oak
yes
i plan to make it more of a hybrid beetween locomotion and teleporting
basically still allowing people to teleport
digital marlin
Can I not pass a pointer from Server to Client?
wicked oak
you can, if the pointer is a fully replicated object
still not recommended
repnotify best
wintry escarp
can morph targets change the texture as well or just move the vertices?
wicked oak
vertices only
digital marlin
repnotify - yeah, good point.
Just odd that NetMulti would work and sending it to Client wouldn't.
It's originating from the server.
mighty carbon
Lol, $.99 for a short experience is "overpriced".
So, yeah, mobile and mobile VR are fucked up platforms
I bet if I could price it at $.49 they would still think it's expensive
But paying $4 for coffee, every morning, is norm...
(In US at least)
quaint loom
@mighty carbon people are funny that way. $4 for a coffee is cheap compared to some folks I've seen drop $10 at starbucks 3x a day.. instead of a few bucks once for a quality of life improvement
tired tree
He was reviewing it as a demo for a full release game at some point, not entirely sure he understood what you were going for.
Also unless you are severely desensitized to it the effects of coffee can last 4-6 hours for the effect. It is not that good of a comparison for a money to time value comparison with a game. Kind of hate that example being thrown around everywhere as "everything wrong with consumers"
quaint loom
I think the analogy hides the fact that there is also the bias that items that are very cheaply priced tend to be viewed as damaged or of inferior worth whereas this may or may not be the case. A bias that most people have though. Which could limit sales also. Whereas with a coffee (keeping to analogy) people know the product well after buying X of them and there is not real risk of variance as it's a controlled substance & product
which is more in line with your comment. Consumers are funny in general; many biases they do and do not realize are in play
quaint loom
agreed, that would be a better analogy
mighty carbon
But yeah, nowhere I advertise it as a game
It's a bite-size consumable experience
Mobile audience is extremely entitled crowd
Btw, 15 min VR porn vids of horrible quality go for $5

glossy agate
How are you reloading? Like a hip hitbox?
wicked oak
yes
mighty carbon
@tired tree small cup of coffee effect lasts for as long as I drink it. I'd need Red Bull to have 4 hrs effect
wicked oak
its incredibly generous, so essentially a flip of the gun triggers it
tired tree
redbull has less caffine, no idea how you can claim that
mighty carbon
Huh?
quaint loom
@wicked oak have you found a good quaternion solution in blueprints by chance? Forums seem to say that it's a C++ coding level thing with Epic wanting to reduce complexity of BP system for beginners (I'd rather have the functionality than reduced toolset). Also, always find your prototypes interesting and can see the incremental augments
wicked oak
no becouse i code most stuff in c++
tired tree
most blueprint rotations resolve to quats now
glossy agate
Nice, do you drop mag first or just have to overlap? Wish gunheart did that, but they just used a reload button which doesn't make sense in VR when you come for interactivity.
wicked oak
its overlap + angle
so gun needs to be pointing down and be roughly at the hip
then it triggers and reloads instantly
quaint loom
so not as simple as Raw Data which is just an overlap check (or appeared to be)
quaint loom
for the upgraded reload part of akimbo shooter
wicked oak
and it is very very generous at the moment, so its simpler than the raw data one
i made the enemies shoot in bursts, wich is a lot more interesting that just constant fire
quaint loom
more pleasant for the ears too. More satisfying than a constant stream which your brain will eventually dull and filter to some extent
wicked oak
like dwvr...
quaint loom
ie chaingun from TFC way back when
wicked oak
some of the things im doing here im thinking of adding them to dwvr
quaint loom
how is the market recieving the multi-platform aspect of dwvr btw? Know you just released it was it last week? week before? (time is becoming a blur again)
wicked oak
more sales than PC
on ps4
i still havent launched in europe
game is getting review by PEGI at the moment
once i have it ill launch in europe
quaint loom
how long was the rating system process elsewhere? few weeks/months?
quaint loom
that's not bad
quaint loom
@tired tree thanks. I'll be looking more into that today 😃 . Was experimenting with ways to get absolute and relative rotation last night via BP for an interactable
tired tree
you aren't working in quats in blueprint
quaint loom
is ps4 just that backlogged or less streamlined you figure?
quaint loom
yea I figured that after Epics comment of reducing complexity. Hiding it in there. Makes sense to use the quats math as it's faster computationally
wicked oak
@quaint loom both
tired tree
just about everything uses them in the back end
quaint loom
Relative rotation was pretty easy with Unity and Quaternions. Trying to use UE4 BPs for this however. At least for now. Makes me wonder what else has been hidden away from BPs and much simpler in C++
late night UE BP sessions aren't the most productive. was rotating a cube along Z axis by dynamic system which yielded 90degree Z rots. Dived into debug for a bit as the cube didn't appear to be rotating. Fixed it with timelapse to see it but 4am scripting/coding not the greatest.. lol
glossy agate
Anyone here mess with the Steam Audio plugin yet?
glossy agate
Just tried it. So awesome
glossy agate
Was working on just the opening lobby house for players to join or host. Much better performance with this baked lighting (and tiny level). Also used the Steam audio plugin and that works real nice. https://youtu.be/g_ZNuswdtSw
wicked oak
that is really cool @glossy agate
glossy agate
If you listen to it with headphones on it gives you stereo sound similar to in game
wicked oak
what is the plan for the final game?
btw, alt-enter fullscreens
and even if not fulscreen, you can configure OBS to only record the center of the screen
glossy agate
Yeah was trying alt enter and couldn't get it to work still haha. Probably user error.
glossy agate
Its going to be tactical multiplayer, really similar to the last of us multiplayer. More looting and ambushing instead of run and gun. Also have a single elimination hostage mode. The defending team has to keep them alive while attacking team has to kill the hostages. Ill have levers you have to control or something to move a saw that will cut the hostages to win.
Yeah haha. I got Unity so I could get marketplace assets to port to UE4
wicked oak
how are you testing MP now?
btw, multiplayer gamers dont give a crap about graphics
but you need a starter audience so marketing is KEY
maybe some free alpha or similar if you are very proud of your game
glossy agate
Havn't tested yet, besides 2D replication testing. Buying my new app ID in a couple weeks.
Yeah, Im goin the same route Pavlov did with free demo before launch of a single map to get feedback.
Im watching Skyfront too, to see how their campaign goes. Really heavy ads just during Beta. Seems to be working though.
wicked oak
just dropping off the beta wont work well, but you can try to release the beta version of the game as a "game on itself on steam"
that way people can join the beta through steam
and it will apear on the "new now" lists
i think you can add the beta as a demo in steamworks
that would work perfectly
but even IF you do that, you still need some marketing
glossy agate
Yeah thats the plan. I play a lot of Onward, and was on a team for a bit, so I am trying to bring all the people I play with over to my game
wicked oak
drop a cool video or something like that on reddit and others
that can give you very good testing
your demo launch is like the final launch
the better the demo the more sales you get
how are you going to host the servers?
i thought of using amazon game servers
becouse listen servers will not work well
glossy agate
AWS Gamelift or Photon
wicked oak
yeah, gamelift
glossy agate
Has that cool auto scaling to keep costs down
wicked oak
even onward, the most important vr multiplayer game, will not go past 200-300 dollars a month in amazon
becouse not really that many matches going at once
maybe 10-30
Peak concurrent players yesterday: 149
assuming 6 players per match that is 25 matches
if you run 1 gamelift small per server, that is 25 servers at i think 20$ a month
for the peak
glossy agate
Yeah its so cheap. Onward was on Photon just using free tier for a long time. Not sure if they have had to move yet
glossy agate
Haha yeah, perfect for VR sized audiences right now
wicked oak
that is ridiculously cheap
comparing unreal servers to that...
you need to use full blown servers for your unreal servers, instead of that cloud thing that is so cheap..
glossy agate
Wait you have to have your own dedicated to use this with unreal?
glossy agate
Damn that sucks. Must be why Pavlov uses gamelift instead.
wicked oak
@glossy agate look at one of the comments about the gamelift thing
the guy says that pubg starts players in a lobby/matchmaking server
and the matchmaking server then creates the new gamelift server and sends the players there
glossy agate
Ah nice. So they can get 100 players on just one server, I probably won't ever need more than 1 haha
wicked oak
the matchmaking approach is a good one
you really do not want your game client to be able to create amazon instances
what if suddenly players go each into 1 server
it would get super expensive very fast
glossy agate
Yeah. I don't know much about networking but was thinking maybe you can locally host for everyone to join, then migrate onto the aws server when host clicks start.
Since my game is only 4v4
Just need the start lobby for people to select teams and loadouts.
wicked oak
that start lobby would be the game server already
in fact, what i was planning was to have an actual lobby
with maybe 10-20 players
essentially, the game just looks at the master server list (from steam) and joins the first availible lobby map
and from there, he can interact with other players and go into a match
glossy agate
Ooh I get what you mean now. Everyone one 1 server for match making, then just shuffle them off into new servers when you start a match. Yeah that's a really good idea.
I'm gonna need to hire more professionals to help me with that.
wicked oak
you could do that quite well
have some kind of firing range/lobby for up to 20 people
and the matchmaker
glossy agate
Gunheart does something similar. It's like a bar that everyone hangs out in until you create a game for people to join.
wicked oak
thats exactly what i had planned for my game
you should start with this stuff ASAP
use your onward colleages as a testers
glossy agate
Trying too. Only started in Late June with it. Another couple weeks of work I think I can upload it to steam to start testing and programming game modes.
But I have been thinking about this game since 2014 before I even thought about making VR games
Anyone here play BAM? Looks like they just released a battle royale mode. Guess it's pretty fun
Just wanted to know if it actually works good with the small audience that game has.
wintry escarp
ue4 does olde style hosting doesn't it? where one person can be the server
full junco
@mighty carbon a 1 minute experience has to be very, very good relative to most other available stuff to be worth $1 I think.
almost all games cost way, way less than $1 per minute
wintry escarp
do blob shadows work in vr or do they stick out as wrong
full junco
@@mighty carbon when I look at what I played most the last few years, I'm at $0.0006 per minute. that's so many orders of magnitude less.
one or two orders of magnitude more are fine for vr I guess, but more is just too much I think
uneven moon
@wicked oak When you released on Steam, was there any kind of delay before you got complete sales analytics or is it real-time from the moment you publish?
mighty carbon
@full junco mine is good and totals from 5 to 10 min. depending whether you just want to get it over with or stick around and explore.
glossy agate
@uneven moon mine were pretty much real time

@wintry escarp blob shadows work fine, and are very cheap, I use them.

anyone experience flickering (AA problem, looks like) and found a solution?
using a stationary light with area shadows
weak tide
@uneven moon you got temporal AA turned on?
we switched setting over to temporal this morning on a VR project due to flickering, problem went away
uneven moon
Yeah, temporal AA in project settings > rendering is selected
Unless there's more to do than just that?
Using the forward renderer with instanced stereo, as well
weak tide
Nice
Reminds me, I want some of those knuckles from valve
Anyone got a preference of current high-powered VR backpacks? Got a big show in Jan we need some for
wicked oak
thats more or less the reason XD
weak tide
the downside of the backpacks is they don't make very good desktop machines
wicked oak
laptop + tpcast would be a lot better
a backpack is far too locked into a vr machine, while a laptop can act as a mobile workstation
weak tide
"Using a fairly new Anker 20100 battery we had sitting around the office, we got a solid 4.5 hours of consistent play time." - wow (TPCast)
oo, it's showing as available on scan.co.uk delivery 24th of this month
ah that's cool - they've designed it to integrate with standalone Anker battery packs. This could be the answer for us

congrats to the dev of Wrench becouse he is getting free gpus from nvidia
i remember he was in this chat

aight, payday 2 would be fun in Vr

Yeah coop is gonna be sweet

haven't played that one..
weak tide
some free GPUs would be nice
anyone had any luck with the nvidia vrworks branch and per-eye SLI?
wicked oak
@sly elk congrats
free gpus best gpus
what are they sending you?
ive been incredibly dismissive of this program due to the "beg in social media" part
im completely fine with shilling, but its shilling without even knowing if you are going to get it, begging on social media
sly elk
Yeah. They sent me a 1080ti
which is great for me. I do so much scan processing and reality capture is much faster now
I have always avoided social media but doing a game like this I have to get comfortable with schilling 😃
wicked oak
no issue with shilling, is about the begging part i dont really like
i think its scummy of nvidia

Anyone know of a way to make actors from blueprint objects that are not viewable or editable? I am sharing some functionality with a client but I don't to give them all my source blueprints. Basically, I want to make a plugin that spits out files based on some work in the editor. Any suggestions t o get me started on reading material?
sly elk
so there is no way to make a plugin that spits out game objects they can't open up and look at?
wicked oak
no
tired tree
@sly elk i'm curious, did you actually enter into an agreement with Mazda for your project?
mighty carbon
btw, not VR related but I read somewhere this morning that Law Breakers concurrent players count dropped to 10
10!!!!!!
glossy agate
Dang, DOA
Not sure why that one just never stuck. Looked cool, but I guess its an overwatch clone, and overwatch has actual likable characters.
tired tree
oh, so they are at top 10 VR multiplayer game levels now eh?
glossy agate
Haha, maybe even top 5^
sly elk
no, i have a license agreement with a kit car manufacturer
tired tree
ah, so you are going to be replacing your mazda scans with their parts then?
mighty carbon
so, no one plays VR multiplayer? o.O
tired tree
rec room is both free, and one of the, if not THE most played VR multiplayer games
so no..compared to normal games ,there isn't much concurrent player base
glossy agate
I think a good portion if not most play some kind of MP a lot. Just a tiny audience overall.
At least the audience that buys lots of games play MP.
sly elk
nope, im not redoing parts. i met with an IP lawyer to discuss trademark infringement issues before starting my project. There isn't any trademark issue with using scans of mazda parts. Just nothing like bodywork. Trademark is about source of goods and no reasonable person looking at a cast caliper is going to assume the source of the work is mazda. Also, most of these parts are manufactured by the aftermarket at this point. You could build nearly an entire car with non mazda parts.
mighty carbon
sounds like someone has a lot of money to throw around 😉
tired tree
@sly elk was more worried about the engine cover and the like having visible logo's
but if you have it covered then cool, your project is nice
sly elk
i'll probably scrub that but my lawyer says i don't need to
thanks 😃
also I trust my lawyer on this stuff. His firm has done IP deals with the big 3 us automakers. I had a bunch of questions about this before committing my savings to the project.
tired tree
would be nice if it gets big enough that you could interest an auto maker
they have very detailed full CAD files
would be missing aluminum pitting and wear but would be far easier to source off of :p
sly elk
Yeah. Im being totally anal about the art quality for the game. I probably wouldn't use much cad. Maybe as a base to sculpt on. In the future, I might to tiered content quality and have some less detailed art cars. Building art like this is super time consuming
like have A quality cars and B quality
same mechanical complexity, one less detailed
glossy agate
Thats what I was thinking too. Licensing the template of your project for auto makers to create training simulations.
sly elk
im aleady working on that part 😃
weak tide
We had some good feedback from salon equipment manufacturers recently. Showed some demos, and we got access to the CAD files for a load of stuff from quite a few manufacturers

Just took a huge performance hit for no reason and without doing anything new. When I hit simulate it runs at 120 FPS and when I hold down the right mouse button to look around, it drops to 45 FPS even though I haven't even rotated the camera yet. GPU drivers are up to date
Tried restarting the engine, the PC, no luck
I was also getting massive FPS drops when I'd hover over or click on the content browser, like as low as 5-10 FPS
I disabled real-time thumbnails and it fixed the content browser bit, but it never used to happen before
GTX 1080, 16GB, i7700K
Anyone know what's happening?
Same thing in a blank level but it goes from 120 FPS to 90 FPS when right mouse click held down

@mighty carbon got a VR project for a hair-care company for CES in Jan

Anyone with recent expertise doing 360 video? I've been trying to use the panoramic plug-in but I've been getting horizontal lines in the captures

@uneven moon the editor is doing some strange stuff when it has captured the mouse, so when you hold the right mouse button, I think I also noticed that a few times. its just an editor thing though, in packaged it won't affect the fps
digital marlin
that dell headpiece thing looks underwhelming tbh
weak tide
I just noticed from a screen recording that the mirrored output on screen is smaller than the output to the HMD. Is there a way to adjust that?
tired tree
its accounting for the warp applied to the image, but the area that Epic is using is significantly smaller than what everyone manually did before the new spectator system
you would have to go into engine source and adjust the rect
weak tide
I found some new docs - got a better view now 👍
vr.SpectatorScreenMode was what I needed

thing is, I'm having to demonstrate the pixel resolution in a 2D video, and the standard view mode is too cropped. The warp I can live with

Trying to optimize my VR build... I am trying to change a light BP to static as it is making shadow casting errors ..Unreal crashes everytime...I've tried setting editor window to NOT play Realtime but it keeps crashing
wicked oak
i wonder if steam audio will work on ps4
as it works on android wich is already a limited thing
is it "fully" open source?
becouse if it isnt i cant recompile the dll
mighty carbon
tired tree
@mighty carbon thus the github branch for early adopters, though it will still be rolled into engine updates anyway
mighty carbon
yeah, I know.. Just royal pita to build UE4 😦 (takes too long; I better use that time for production/design)
tired tree
Well steam audio is something you can upgrade later on if you update engine versions anyway, and it should only get better with minor procedure changes
so I don't think it should really matter to you at the start
mighty carbon
correct
tired tree
maybe once sound design is fleshed out it could be a wall, but not early on
glossy agate
@mighty carbon Have you tried it yet? Just tried it myself last Sunday, super nice. Even simple stuff adds to the immersion.
mighty carbon
nah, I am working on content right now, then will hit AI.. Most likely by the time I am ready to dig into sound 4.19 will be out 😃
basically until I have AI where I am satisfied with, I am not even going to look into other things
is it any good?
I wonder how it runs on Rift (I still see people saying SteamVR games perform worse on Rift than on Vive)
mighty carbon
I didn't get it for PC.. Read somewhere it wasn't as fun as Portal 2
full junco
@tired tree did you test steam audio stuff yet?
it is nice that they are improving stuff, but in that post regarding the new beta they only mentioned baked stuff, so I'm not sure how much they are working on the fully dynamic side of it
tired tree
haven't tested it yet no
it has support for dynamic occluders
but I don't think it is supposed to be fully dynamic
more hybrid like "Stationary" in engine lighting
so I don't know the performance hits of it
I didn't want to touch it until it was stable, IE: prob 4.18
full junco
I thought it would have a mode for being fully dynamic
wintry escarp
portal2 was the last full price game I bought
mighty carbon
lol
I am torn between Wolfenstein 2 and Talos/Arktika.1 (or whatever else is cool SP for VR)
(not to mention I haven't finished Dishonored 2)
tired tree
well it support dynamic...but the perf cost is really heavy. its primarily being tooled around pre-baked high quality occlusion.
it has both a real-time, and a baked setting for the propagation in the settings
full junco
well, can't it run on its own thread? so is the "really heavy" actually relevant?
tired tree
I don't know the differences in implementation between the ue4 and unity versions
but there are multiple questions about the unity version and dynamic objects being really perf taxing because they are re-exporting the scene...I doubt ue4 has that issue
it still has to run traces regardless though
"own thread" isn't immune to perf issues anyway though...
anyway, they state hundreds of emitters in baked, if dynamic performs well with 1/5th of that then its still good anyway
no reference point or context without trying it yourself really, you are one of the few doing fully dynamic vr content around here
full junco
yeah, I'll definitely try it when I get to updating my engine

^wrong channel?
mighty carbon
nah, correct channel
tired tree
naw he is asking us specifically
velvet mango
I kinda doubt someone will implement such complex animations in VR
mighty carbon
why not ?
I mean, how is animation in VR different from animation in non-VR games ?
tired tree
that has a lot of custom movement logic, you likely don't need that for npcs and a lot of the player animation is IK driven
velvet mango
Do I have to list 10 examples from the picture that you usually would not implement in VR?
velvet mango
- what @tired tree said... IK driven
tired tree
it could be, but very unlikely unless going all out AAA on it
mighty carbon
btw, all those "checks", why can't those be done in BP instead of the state machine ?
tired tree
its also probably possible to clean that up
full junco
@mighty carbon why do you ask that in #virtual-reality ?
it doesn't belong here, @velvet mango is right
mighty carbon
because that's where I hang out @full junco 😉
full junco
thats stuff for #animation
mighty carbon
your audio questions belong to #audio @full junco
yet, no one cares.. feel free to ask here..
full junco
if you go to the audio channel, you actually see me talking about audio there
here I only talked about the steam audio stuff that is used for VR
mighty carbon
then keep it there ?
well, anims belong to VR too, in the context of my current project
full junco
then everything belong here, and it shouldn't
velvet mango
in the context of my current VR project, I could post questions from other channels?
you make no sense, mods slept, John got a pass
don't be jealous 😄
mighty carbon
mod? we have mods?
velvet mango
that you didn't get the same treat ❤
full junco
@velvet mango #virtual-reality is a good channel to talk about steam audio, it was specifically integrated into UE4 because of VR, thats where you need HRTF sound most. so it does belong here, its not that mods "slept"
mighty carbon
🙄
wintry escarp
looks like kite demo doesn't work at all on 4.18
full junco
and I actually only mentioned steam audio because of @mighty carbon, he posted a blog article about a steam audio update
velvet mango
I can make a connection with VR and audio issues that could arise, but not with complex animations, except it's about the player character
full junco
yeah, if you talk about whats the best way to animate a virtual hand or something like that with the least discomfort in VR, then that surely belong here
wicked oak
what the fuck is that anim thing
seriously WHAT
there are substates and the like for a reason
tired tree
yeah....
wicked oak
you can blend several state machines and have tree state machines

it looks like some of the bad BP node graphs I have seen posted as examples of "how bad ue4 is"
mighty carbon
@wicked oak where can I read about all that?
wicked oak
its basic features of the animation editor

just watched a 1:30 hour stream of someone (german journalist) setting up a windows mixed reality headset, he compared it a lot with the rift and he says the FOV is significantly worse
but he expects the cheap windows headsets to be below $200 before christmas
I don't get why microsoft doesn't put the bluetooth stuff into the headset, they want everyone to buy a seperate bluetooth stick for their PC
sturdy coral
maybe to speed FCC approval
alpine torrent
@full junco could that pc be as a other point to calculate location? as those headset what i understanded one video from dell that controllers position based on headsted so it have bluetooth
full junco
🤔
sturdy coral
I heard from someone who tried several that the HP one is the most comfortable, plus it flips up for going back and forth in development.
full junco
its all the same hardware essentially, only samsung did their own
sturdy coral
he said the HP was much more comfortable than the Acer
I think the acer uses some kind of ratcheting strap
the samsung I've heard is really heavy, but I didn't hear from anyone who tried it
alpine torrent
when i tried hololens one time as it was fast so i didnt had time for Place it properly so it was moving but when you put headset correctly so it fit nicely so it shouldnt be too heavy if it is designed well
full junco
the acer one has same weight like the rift it seems

oculus announced oculus home where you are in virtual home
sturdy coral
oh, well they have always called it home
I'm not sure when they are rolling out the new one, it is going to be based on ue4 instead of unity
alpine torrent
mixed reality home is for all Windows mixed reality headsets
sturdy coral
they've always called this thing Oculus Home: http://vrtalk.com/forum/attachment.php?attachmentid=462&d=1466711461
but yeah, they are changing it a lot
full junco
let's see when valve updates their home stuff
or they actually did, right?
that beta stuff that I turned off because it played bird sounds that I constantly heard even while I wasn't in vr 😄
sturdy coral
yeah I turned it off because it always seemed to hog cpu even when I didn't have the headset on
full junco
I never even looked at it, is it similar to the new oculus home?
full junco
destinations?
sturdy coral
but added a bit more customizability with placing objects and stuff in vr
destinations was their sort of VR area where you could just load environments from steam
they eventually added multiplayer to it and stuff and now it has pretty much just become steamvr home
full junco
ah
sturdy coral
they had a lot of their photogrammetry scenes and stuff in it that didn't make it into The Lab
but they also had steam workshop support where anyone could upload scenes to it
sturdy coral
yeah, it is worth checking out some of the photogrammetry stuff, but there isn't a lot of it
full junco
the stuff in the lab was nice to show to people that haven't done vr before
the photogrammetry
sturdy coral
they have one that is the valve offices/lounge that is really well done
and this church/cemetary in england
alpine torrent
it would be interesting how this mixed reality home work steamvr as if the valve is making steamvr home so it could make that you can travel from your cliff house to steamvr home where is your steam vr stuff
full junco
hm, maybe I actually looked at it?
sturdy coral
@alpine torrent I doubt there will be any connectivity between the two
full junco
yeah, won't connect
sturdy coral
you can apparently replace steam home with any arbitrary .exe and have that be your default place, but I don't think it is officially supported with a real place in the settings menu or anything
just kind of a hack
sturdy coral
I think so but I'm not certain
alpine torrent
steamvr home is using source engine?
sturdy coral
it might be unity but I think it is source 2
tired tree
@sturdy coral @full junco not only that, SteamVRHome crashes the SteamSubsystem in ue4, probably uses some of the same dlls and conflicts somehow with multiple accessing apps
so you can't host or join steam servers with it enabled for testing, only once your app is actually launched from steam itself so it turns off home on launch
tired tree
no its in every one as an experimental option
full junco
if the windows headsets are at $200 before christmas, that would definitely be interesting
sturdy coral
I doubt they will go that low, except maybe during black friday
but it will be so soon after release
alpine torrent
the samsung HMD Odyssey comes to market in November 6th
sturdy coral
I wish they would add some kind of external camera thing as an option
so at home/in your main play area you have some occlusion resistance, but you can still take it easily on the road with a decent laptop
full junco
yeah
sturdy coral
that new surfacebook looks pretty nice, expensive as hell though
around $3k with a 1060 gpu

full junco
not laptop
full junco
well they can't sell more than 100 of those because they can't get the rx 580 😛
also its vr min spec, so you shouldn't pay $600 just for the GPU for min spec
so interesting is the price of that with a gtx 1080

i can install Linux terminals to my pc so i support Linux?
full junco
yes?
I want to support linux because I dislike microsoft
thats essentially all reason for it
alpine torrent
well I install Linux terminals to my Windows pc
full junco
what terminals are you talking about?
sturdy coral
probably WSL
full junco
only thing annoying about linux is that nvidia is bad when it comes to drivers for that I think
AMD is doing it great there
alpine torrent
oh snap, using Linux terminals in Mixed reality
@sturdy coral well WSL is the magic flavor in that but there is Linux terminals now in Windows store
sturdy coral
that uses WSL
and it is basically everything except linux
all the userland, no actual linux kernel
alpine torrent
well Linux subsystem
sturdy coral
WSL = windows subsystem for linux
full junco
you definitely wouldnt test a linux game on windows with the linux subsystem
sturdy coral
it basically wraps the linux system api to the windows kernel, not much linux actually involved
alpine torrent
well think you write Linux game from Windows and perhaps from mixed reality then deploy to Linux box and see the remote connection to Linux device and see it running
full junco
unnessessary complexity
I'd just install linux on my pc so I can dual boot into linux

you should test games exactly how someone who plays the game would play it

you can stream pc games to console but you cant stream vr games to headset remotely?

totally different stuff
its horrible how I'm working for like 3.5 months on the trailer now, I should finish that stupid thing
its just so boring to do trailer stuff that I find other stuff to work on instead...
glossy agate
Haha how is it taking 3.5 months? You can get Ae templates online to make it easier. They have some cool effects. Just plug footage into the blank spots.
uneven moon
Any reason the motion controllers default pos and rot can't be changed?
My hands positioning is way off on the Vive but perfect on Oculus
full junco
@glossy agate I haven't even started stuff in AE yet, what takes so long is the capturing stuff in the game...
glossy agate
yeah. I had maybe 2-3 hours of footage for like 1.5 minutes and my game was high action. Gotta play wierd too so it all gets in the frame
full junco
yeah if I would have 2-3 hours of footage I would be super happy
I also only want to have 1.5 minutes in the trailer, but capturing stuff is sooooo annoying
mostly because I always capture with scene capture and spectator screen stuff
so fps are very bad in VR and graphics look bad too
and due to bad fps I quickly get motion sickness
frail portal
I'm pretty excited, I think our VR device will be out around the begining of the year 😄
w0000t
sturdy coral
@uneven moon just attach with a different offset
or make a subcomponent with a different transform and attach to that (or socket, etc.)
frail portal
Anyone else having trouble with general VR locomotion?
tired tree
whew, so the new LateUpdate code in 4.18 has a few issues
since it is queuing the late update now to avoid thread racing in game and render, it applies the final late update the one frame later in render thread after the object is no longer late updated
so if you don't move or update that objects component to world afterwards, it retains an extra offset from it.....
detaching doesn't have the issue, it already updates the component to world
tired tree
actually...come to think of it...doubt any of you guys are going to have an issue with it, you all turn off late updates or attach generally
full junco
@tired tree attach what?
full junco
how's that related to the issue you mentioned?
I didn't really understand the issue you described
what do you mean with "move or update the objects components afterwards"? how can you move or update it after the late update happened? I think you can't?
tired tree
talking about after release of the object
the render thread applies the last update now from the queued secondary array after release
detaching calls updatecomponenttoworld so it ends up overriding the last render thread offset
but if you are doing something that doesn't detach you have to manually update the component to ensure it is correct
full junco
@tired tree I think I still don't fully understand what you mean, how is anyone "releasing" an object from where it is attached without "detaching" it?
tired tree
I don't attach for my grip logic
I move to parrot the hands
i also apply late updates to simulating grips
full junco
"to parrot the hands"?
full junco
ah, so he means he just sets the location of stuff to the location where the hand is?
glossy agate
Yep. Not exactly sure how he does it but I think it allows the extra interactivity where the thing you hold interacts with other stuff you bump into
full junco
ok, the parrot just confused me 😄 https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcSCWYCDpTVawHW9Ut3wv0jHdd_bCIPauAX0KyPC-mcwlToFpcvXQw
glossy agate
Instead of welded bodies where it's just stuck.
Haha yeah, I remember you were from Germany so you may not have heard that one before.
full junco
yeah, thanks 😄
@tired tree but how can you apply late update to stuff thats simulating physics? you really do that?
full junco
so for one frame it can shoot over?
tired tree
yeah but its not very noticable, its configurable too
its an enum whether it allow late on them or not
tired tree
I didn't like the built in physics handles
they have some major downsides if you want "perfect" physics grips
i just do custom constraints so I can fully handle the logic
full junco
would like to see a comparison between physics handles and what you are doing
tired tree
I don't even remember everything that I changed from the default physics handle setup
but for instance....things look parented when not in collision
its like they are attached visually, only very minor delay on rotational axis's if moved very very quickly and that is dependant on constraint strength and can be resolved
I have a different grip type that just moves to follow the hand but when in collision becomes a physics constraint too
as an alternative
that shows it pretty well
@full junco
that is the physics constraint grip
I improve the stability by gripping at the COM of the object, so there isn't wobble, and then to account for correct pivot point I apply a COM offset on grip to the hand location
you'll notice that gripping long things at the end tends to go terribly wrong with the normal handle
full junco
hm, interesting
physics handles work perfect for me (apart from that they are more laggy than late updated stuff), while your stuff in the video is sometimes jumping around a bit, are you sure physics handles aren't more stable?
tired tree
the jumping is the physics body
I just autogenerated it and it jitters when being pressed into things
plus that gun has a very strong constraint
the actual constraint creation is basically the same as physics handles
except for the COM and turning off gravity to account for a slight offset downward
full junco
ok, I guess at some point I should just look at your plugin and compare it with regular physics handles
I just really dislike being dependent on plugins
tired tree
the gravity thing is nitpicking btw
its just that when holding something out and gripping and releasing it over and over the object would trend downward by fractions of a unit over time
due to the force of gravity
it bugged me
full junco
I saw it in your video, yeah
tired tree
oh, forgot that was the video that had that in it
oh yeah, thats the same one talking about the bug that they fixed in the next preview too
I should edit that last bit out since its not relevent anymore
full junco
which bug?
tired tree
preview 2 had weird issues with scaling physics objects in 4.17
it was fixed by preview 3
full junco
ah
one reason why I don't want to be dependent on plugins is that I at any time want to be able to just move to current master without having to figure out how to fix stuff that breaks in plugins
and I guess quite a bit of stuff can break in a plugin like yours
tired tree
its open source, not intended for everyone
its an example
anything you like, rip out of it at will
never going to say I do everything perfectly, just trying to do "everything" to figure it out
unless you mean blueprint
because yeah, then you are kind of limited
full junco
I'm using c++, though when I setup physics handles or stuff like that, that I do in BP
tired tree
yeah I run all logic and movement commands and control in blueprint as examples for people
figure that if someone wants it in c++ they are probably proficient enough to convert to it
bu the other way around is harder
full junco
but didn't you say you built everything in your plugin connected to your custom vr character?

I didn't look at your code, but I would think if you connect everything together in one character class, its not that nice to strip out individual things

oh
i was talking abou the constraint creation
and the modifications to it over the physics handle
the controllers handle all of the gripping
characters are just there for some specific overrides and to spawn the child components and custom movement components

when you say "controllers", what do you mean?
player controllers, some custom motion controller components?

custom motion controllers
its how I originally tapped into late updates, kind of wish I did it as a seperate component with its own FSceneView in the end but sacrifices kind of have to be made to keep things intact for users.
have several "features" I actually wish I could drop to enforce doing it the right way :p

a controller with its own FSceneView? 🤔

why can't you do stuff the "right" way now? you don't need to stay 100% compatible in newer versions
tired tree
lots of people updating nearly complete games with engine versions
full junco
when epic went from ue3 to ue4 they broke all compatibility
tired tree
and its not a huge problem for most of it
full junco
and you could keep an old legacy component and do stuff the "right" way in some new component
