sly elk
No sure yet. I haven't had time to look at that at all. Epic store def looks cool though
next up is oculus store release
sonic lake
@sly elk LOL true! Hopefully there will be more playing by the users than fixing by you. 😉
frigid kite
is it just you working on it?
sly elk
Two of us
Myself and Jim Ashcraft (former lead core engineer for bosskey)
So for those who have rleased games on steam. Are fake key review requests a thing?
I just got 4 emails, all from gmail accounts, not domains rleated to their websites, asking for review keys. All very similar
sturdy coral
congrats on launching!
I've see lots of threads on r/gamedev about fake key requests but have no experience
frigid kite
And have you been doing it fulltime or after hours?
sturdy canyon
yeah lots of fake key requests on Steam @sly elk
frigid kite
I'm also working on a project myself and I'm interested to hear your experience
sturdy canyon
I generally ask people to leave a comment on my trailer to prove they own a YouTube channel
Everyone asking for keys is used to the distrust now, so don't be afraid to insult people by asking for proof
sly elk
yeah
but also in teh scheme of things 10 keys a day being sent out and 1 in 10 is legit and might bring me 50-100k views or something
seems like a worthwhile cost
ornate raptor
I've been ignoring the requests for multiple keys. Those seem pretty transparently fake
I can't imagine why someone would need more than a single key to review a game for a youtube channel
mighty carbon
Bosskey.. Is CliffyB also participating @sly elk ? 😃
sly elk
hah, no. maybe we will get lucky and he will retweet
potent gust
Has anyone tried cross platform chat between Oculus Go and Windows builds?
sturdy canyon
Voice chat?
I tried it in 4.16 or something, but never actually got it working
If you get something working @potent gust please let me know! It's on my TODO list before Quest launch
potent gust
But is it possible?
sturdy coral
@potent gust have you tested?
potent gust
Attempting various ways, but havent gotten anywhere yet. @sturdy coral
What have you got?
sturdy canyon
most online subsystems have their own private voice chat implementations
sturdy coral
I haven't tried, but I've done stuff with steam voice in the past
sturdy canyon
online subsystem null is the only one with engine-built-in voice chat
sturdy coral
they both have the same online subsystem so I think it should be possible
online subsystem steam recently moved to using the built in engine voice chat instead of the steam api
sturdy canyon
ohhh if you're sticking to oculus on desktop, yeah you can probably do cross platform with their online subsystem
whaaaat that's awesome!
potent gust
yeah, but this is more like Android + Windows
sturdy coral
at least for the voice recording part of it, and the voice packet stuff
potent gust
And the android is more like "Wait! Im an Oculus!"
sturdy canyon
I haven't tested any of this in a while
sturdy coral
@potent gust it should work, they usually serialize things in a way that works between android and windows
sturdy canyon
I just gave up on voice chat
sturdy coral
the main thing is if it is based on app-id like steam
the gear vr and desktop version may have a different app id
I'm not sure how that works
sturdy canyon
yeah they have different IDs
potent gust
The engine spacialisation doesnt work in Oculus Go. Wonder what else doesnt work.
sturdy coral
yeah, it may not be possible then without adding your own network layer
or using dedicated servers
sturdy coral
to get around the app id limitation
sturdy canyon
What makes it easier with dedicated servers?
potent gust
What about off market apps?
sturdy coral
peer to peer can only communicate on the same app id
potent gust
Yeah
sturdy coral
with some work you can make dedicated merge multiple app ids
at least on steam
off market apps I have no idea, they probably can't use the oculus online subsystem
potent gust
Well, im my experience, oculus's sound implementation is a 'STEAMING' pile of shit
Using null subsystem
sturdy coral
using null then there is no issue
potent gust
Are you sure?
sturdy coral
yes, you can use voice between android and windows on null I am pretty sure
potent gust
Arent the codecs different?
sturdy coral
both encode with opus and use a packet structure that uses standard enough serialization it should work
but you have to add your own peer to peer hole punching if you want to make that work without a dedicated server
sturdy coral
I'm not even sure you can hole-punch on mobile
sturdy coral
@potent gust you'd be wanting peer to peer over null subsystem?
potent gust
yeah.
sturdy coral
and over the internet, not LAN, with mobile and non-mobile users right?
@potent gust I could work on it, but probably not until sometime in 2019
you might want to wait and see how this shakes out too: https://www.unrealengine.com/en-US/blog/epic-2019-cross-platform-online-services-roadmap
no specific mention of oculus, but they do mention cross-platform voice
I'm not sure if they are going to have their own NAT hole-punching stuff etc., but there is some stuff around that in the new pixel streaming API
potent gust
Damn. That's awesome
sturdy canyon
I'm planning on testing voice stuff using NULL with dedicated servers today
or maybe tomorrow I'll get to the testing part
P2P will be interesting...
But currently SculptrVR uses dedicated servers anyway, since it's hard to do cross platform otherwise
sturdy canyon
I'm getting some strange behavior from the head camera on Oculus Go
My perspective is rendered from ~140cm up from the character zero
but when I get the world position of the head camera, it gives me the room center
so the scene is being rendered from a different perspective than the camera position query returns
I need to know the player head pos for networking, etc
anyone know what functions I should actually be using on Go/GearVR?
mighty carbon
get position of the camera anchor ?
sturdy canyon
Camera anchor? Is that different than the camera?
The camera is child of a scene component, but that component doesn't get shifted on Go
mighty carbon
well, since Go is 3DoF, camera doesn't move really
player character moves and camera follows
sturdy canyon
Yeah, but when I call get camera location, it is not giving me the actual camera location. It's giving me a point 150cm below the camera
Maybe there's a height parameter in the Oculus runtime or something and they have chosen to add that in at the last moment and not actually update the camera location
sturdy canyon
I'll look into it! Thank you!
mighty carbon
np, I am just guessing though 😃 I never needed to get camera's position as I am usually fine with player's location
trail shale
I'm trying to rotate a valve handle, it's working but it doesn't feel right, like something is fighting me or it's just not that smooth.....any ideas? (the axis works correctly)
hand = motion controller
sturdy coral
@trail shale why times -2?
trail shale
the negative inverts the direction, like a flight stick...without it being negative, the movement feels backwards
doubling it because the rotation didn't seem to work as "fast" you kept having to turn your right but it didn't seem to sync with the valve
actually that lets me think of something, I wonder if I need the hand'
rotation to be relative to the valve - thought I could get away with because you usually approach from the same axis angle but it would explain it
sturdy coral
yeah I think you need the compose transforms thing we talked about the other day
to treat the hand as if it is in the same relative space as the valve
trail shale
Is there an inverse transform rotation...i bet there is
sturdy coral
you are also going to run into the issue of degrees falling over 180 and stuff
trail shale
could you elaborate please?
sturdy coral
like 180 == -180, 200 == -160 etc.
since you are just copying rotation and not getting a delta maybe it will be ok
but that's another issue
you are just copying the hands rotation, so the valve could be undone on first tick
trail shale
oh, well yes, if you alter your grip on purpose, the valve will jump to match it's rotation seemingly
It's not the end of the world, it's not something you would necessarily do naturally
sturdy coral
you may just want to grab one of the templates that has a valve type thing
and copy from there
trail shale
and if I make the rotation more intuitive, it won't matter as much
sturdy coral
@trail shale there is a pure blueprint lever here: https://forums.unrealengine.com/development-discussion/vr-ar-development/83197-vr-content-examples?p=777762#post777762
and a lever is pretty close to a valve
trail shale
actually the inverse transform thing got it
sturdy coral
it isn't going to feel right if it snaps to initial pose, most people will grab it the same way but some people won't
@trail shale grabbing like a doorknob vs grab like a valve I end up rotating on orthogonal axises
trail shale
what would you recommend?
sturdy coral
also, be aware that with euler rotations things can get really tricky
using yaw and pitch is usually ok, but with any roll things can get way off, gimbal lock etc.
trail shale
this is a secondary function, basically you are rotating valve to around 90 degree and you are locking the handle, so you can't push it in
sturdy coral
I would probably look at somewhere else that did it and see what all they did
trail shale
firefighters do this when they are happy with a valve and don't want it to get messed with
there is a box collision that the valve will collide with if you rotate it close enough, so I don't have to tick the angle range and check it

o.O
sturdy canyon
ok changing "base offset in meters to (0,0,-1.4) and then offsetting the camera parent to (0,0,140.0) fixed it so that my head camera is now located where the view gets rendered from
(this is Oculus Go)
sturdy coral
that's really strange, I wonder why it is offset there
sturdy canyon
I have no idea why this is happening now, since it didn't happen in 4.19
sturdy coral
did you offset it in world space or relative?
sturdy canyon
the "Base Offset in Meters" is an oculus library thing
sturdy coral
ah n/m I see camera parent
sturdy canyon
camera parent is just a scene component in the player character
but I'm worried these offsets are maybe to do with my player profile, and I should be adjusting the numbers differently in different situations
sturdy coral
you can query player profile
but overall it sounds like a bug
I would report it on the oculus github issues maybe?
sturdy canyon
note that this doesn't change the location of rendering at all
all it changes is it fixes my call to "get world location" on the camera component
that now roughly matches the rendering location
mighty carbon
btw, speaking of Oculus fork.. I finally tested my project with Oculus 4.21.1 with 1.32 integration and I keep getting red arrow randomly sticking out of the player when I look down (sometimes it's there, but when I turn or teleport to another location, it disappears and then reappears when I move/look again)
and it's red instead of blue (like all character class derived arrows)
I gotta test with shipping build to see if that's still the case
sly elk
So does anyone know why steam vr launches when I load my game in 2d mode through steam?

Because you have a headset attached and the project is built with the unreal steamvr plugin enabled, I reckon

sly elk
I have a vive user reporting that their vive trackers will randomly lose tracking while playing wrench only
Is that possibly an unreal bug?
pearl tangle
@sly elk what are the vive trackers being used for and how many of them? Because of the way unreal assigns the ID's to things sometimes if it disconnects or whatever it will start tracking a different controller instead
sly elk
- tracking stations
pearl tangle
ah well now that 1 I can't explain, although the lighthouse stations do actually get assigned an ID which is the same as the controllers. So if something fluctuates there then perhaps the controller is taking over from the lighthouse ID instead. Best way to understand that is whether the light changes on the lighthouse itself. If it's losing it's tracking on there then can't be the software, but if it's just the controllers lose tracking then it could be the software side of things

I'm suggesting to some marketplace dev's to release a VR inventory / crafting system.
https://discordapp.com/channels/187217643009212416/222730877505896458/527789667349692417
daring pasture
Pretty sure there are a few inventory/crafting solutions already on the marketplace. Would need to be adapted to vr, but wouldn't take a day or so to do.
granite eagle
I've written up my ideas and posted them as a forum thread. The problem I have with most of the traditional inventory systems is that they're not as intuitive (menu based, point click, etc). I'm thinking more along the lines o the weapon VR systems where you pick up items in a more intuitive VR type experience.
daring pasture
Imo the forest has the most intuitive crafting/building system. It also doesn't appear to be too complicated to recreate. You could check it out for ideas
granite eagle
Yeah Forest crafting system is great, I'll prob include it as an example later. For now I just wan't to keep things scope generic and simple enough to get started on
trail shale
Button pressing in VR - I have a small series of buttons that have to be near one another, so the motion controllers pointer finger collision has to be small...I've animated the buttons to move back into their recess and pop back out and it is firing the overlap event that triggers the button press. My current work around is to have another invisible button that I use as the collision,that way the movement doesn't retrigger it. With that and a pressing button boolean, it works, but I was thinking there had to be a better way. (I'd love a function I could use for all buttons that just took in the button mesh and name as inputs and handles everything else.

this may be a silly question, but who knows - does the FaceAR sample work with the iPhone XS? or is it specific to the X for some technical reason...

it would have to be something like they locked out the face apis for it not to, it has the depth camera
misty elm
thanks @sturdy coral trying to suss out if i'll have less heat issues if i purchase either the XR or XS as opposed to the X.. i think the XR is probably what i'm leaning towards
sturdy coral
@real needle do not advertise vr support if it is badly broken, you will suffer in reviews. I wouldn't expose it at all, except you could make a public beta branch marked experimental
oh, sorry just saw it is going to be free.. I'm not sure there, depends on what your goals are
real needle
@sonic lake have you made any progress with spatial audio on Go? I am running into a situation where on Rift attenuation works fine and on the Go it does not. As I understand you got distance attenuation working on the Go?
sonic lake
@real needle Distance attenuation kind of works. Spatialization doesn't. I tried any combination of plugins / settings but eventually gave up since I don't have time to investigate more in details.
real needle
Did you activate anything else then Oculus Audio for distance attenuation to work?
sonic lake
No, only that one. Works out of the box, but it doesn't have the same dynamics as the Rift version. It's flatter if you ask me.
real needle
yes, the panning does not work on the Go. Which I cannot confirm through Oculus docs. But I can't even get the distance attenuation working. Even though I got it on Rift.
mighty carbon
use FMOD
also check what version of Audio SDK is in stock UE4.. If it's older than 1.18.x, then use Oculus fork of UE4
@real needle ^^
sonic lake
@mighty carbon which audio features did you get to work with FMOD? All of them?
mighty carbon
I haven't gotten to audio yet with 4.21, but with 4.18 I used FMOD and whatever audio SDK Oculus fork had at the time
and all I cared about was spatialization and distance attenuation
those worked
to my ears at least 😃
mighty carbon
but, I want to stop using any 3rd party plugins
cuz if I use FMOD (free), then I am limited to 1 game release annually
(meaning 1 year between games)
sonic lake
Audio management on the Oculus Go is largely undocumented, at least publicly
mighty carbon
Go is a glorified movie player
that's all
it can be more, but Oculus sees that Go is mostly used to watch Netflix and porn
mighty carbon
so, they never fixed controller's d-pad and probably never cared to make sure UE4 and spatialized audio works
wicked oak
it ended up being quite a good successon Japan
becouse they like to use it to watch movies in train or similar
mighty carbon
(you don't need spatialized audio with Netflix and porn)
wicked oak
you do
for the 5.1 stereo stuff
where you have multiple sounds emitter located around you
mighty carbon
Netflix has no 5.1 stereo
none
I don't even think 180 porn has binaural audio
it's just stereo
the point is that Go + UE4 combo is neglected by both Epic and Oculus
which is a shame, because Go can be a solid gaming platform despite being 3DoF
wicked oak
but Quest isnt
and Quest is more or less same thing
Epic games is preparing a robo recall "lite" for quest launch
real needle
@sonic lake was that the Oculus fork of UE4 on which you have distance attenuation working for Go?
wicked oak
but anyway, i dont think ue4 is good for mobile vr
you need ultra low drawcalls
and ue4 doesnt batch
unity does
sonic lake
I understand that the recommendation to develop for Quest is to use the Rift as base
wicked oak
automatically, unity merges your meshes if they have same mat
sonic lake
@real needle No, it was the Launcher version. 4.18.x if I recall correctly.
real needle
bam!! thanks
mighty carbon
I doubt Epic works on RR for Quest since Oculus bought out everything related to RR
even assets
I think Oculus work on RR for Quest internally
and maybe batching is being worked on (and hopefully it will trickle down to public UE4)
@sonic lake have you tried 4.21.1 and Steam Audio on Go ?
sonic lake
@mighty carbon No, I am not developing with 4.21.x yet. Too young. Will give it a try though.
real needle
@mighty carbon installing 4.21.1 right now. Trying to get it working out of the box
would steam audio be an option for Oculus Go?
mighty carbon
well, it supposedly works on Android, so why not?!
you need to activate UE4's new audio system though
real needle
👏
sonic lake
Only if it is related to a shippable product. I am anyway extremely disappointed with the latest Oculus policies. They have no interest at all in supporting any business (aka non-gaming) application.
mighty carbon
lol
no wonder they have bugs - if no one reports it, how is it going to be fixed ?
I always report any bugs I find with repro case
(usually just my project)
sonic lake
The audio problem was discussed on the Oculus forum (also the Start one). Didn't see any useful response so far.
mighty carbon
because there are ways to report issues and post on the forum is not the one of them
sonic lake
I am aware. There is a limited number of issues we can get support for and I didn't want to burn one for a non shippable product.
mighty carbon
eeh, that's not how it works with Start
I still have all my 5 sessions (or however many they let Start members have) intact
since reporting bugs and asking general questions doesn't count against those 5 tech support sessions for Start members
sonic lake
They must like you! 😉
mighty carbon
(and I don't even count on those because right now Oculus is busy getting things done for Quest)
I wish they did
sonic lake
When we complained, in a constructive way, about their policy to force updates on systems without even asking the user if it was the right time to install them, they brushed it off as our problem
mighty carbon
well, don't complain for things that aren't essential 😛
they are platform holder and they will do as their please with updates.. No different than PS4/XB1
sonic lake
Well not really, as their system runs on a supposedly open system like a PC is
Go and Quest are more like platforms in that sense
mighty carbon
PC is not open system
Windows 10 updates whenever it needs to be updated
plus, when they push updates for Oculus, it makes it where everyone are on the same page
sonic lake
Not true. You are never forced to run an update and you can choose to disable them altogether.
mighty carbon
it's a way easier to deal with issues when every single user runs the same build
not on Windows Home
sonic lake
That I fully understand.
It is way more practical for them to run one single version worldwide.
mighty carbon
I get updates when I get them.. I can't choose which ones to install and which ones to omit. Plus, it doesn't make sense not to update Windows due to security problems.
sonic lake
At least they give you a choice.
mighty carbon
like what choice ? "Postpone updates for 10 min"
sonic lake
Oculus doesn't. Not even a simple one like deciding whether to install the update now or on the next day.
mighty carbon
I think it's a made up issue..
I never had any problems with updates from Oculus
and even if they screwed up, they always rolled out hot fix shortly after
sonic lake
Sure. 25 customers calling at once that the system stopped working is a made up issue.
mighty carbon
well, you gotta make sure to design your app in a way it doesn't care for updates 😛
or use Oculus fork of UE4, the latest..
sonic lake
Not easy if the VR core is down because it is updating 😉
mighty carbon
It comes with almost most recent SDK
Also, from my experience, when you use the latest UE4 they are willing to help more eagerly than when you use a dated version (4.18 is old by now)
sonic lake
True. On the other hand we need stability and I cannot afford to deploy on the very latest engine version.
The non-gaming world has different rules I guess.
I am seriously considering dropping Oculus in favour of WMR.
mighty carbon
and forward shading ES3.1 finally works with Go
(there are some minor bugs, but that's specific to my project)
sonic lake
Good to know. We aren't shipping on the Go yet. Just experimenting with it.
Will definitely start experimenting with 4.21.x early Jan.
Also we would need BLE support with it.
mighty carbon
although UE 4.21 should support BLE out of the box
considering that Android support in 4.21 is a way better than in 4.18/19
sonic lake
I know that pairing BT devices to the Go is fairly easy, need to check how that comes across to UE4
mighty carbon
it should just work, since Steam Controller is BLE and UE4 works with it out of the box
sonic lake
Yes but different BLE devices have different services / characteristics. Plus some work by polling and others by subscription.
I am confident it will work though.
It does on Windows with an own communication thread.
sly elk
Its going okay so far. I think our launch date was about the worst choice possible
the day before the winter sale

it was
sly elk
- press outlets are not in the office
so im not bothering to email until the new year
We are planning a big round of promotion in january
We needed the sales income for December though since we won't get the check until january 30. The game is already in a much better state then when we launched and by the time we starting bringing in bigger attention it will be more improved
Right now its pretty intimidating for new users who don't know much about cars, so we are working on that.
Also we found out the airforce used Wrench to pitch a new VR development initiative: https://www.edwards.af.mil/News/Article/1719563/innovation-f-35-maintenance-virtual-realityaugmented-reality-initiative/fbclid/IwAR3rRhgZfolx2y9AGJkQdogDlUxHy9xNQLmyqjp3taatHBCcCNBIV6aJyfs/

It seems like if our software is going to be used to pitch something, you would it would be reasonable to be considered to develop something
sturdy coral
@sly elk re: december launch -- it will nice to split initial sales over two years too for tax bracket purposes

true
Losing our top seller spot on the steam page as soon as the winter sale started was not great though.

@mighty carbon @sonic lake The attenuation issue still exists in 4.21.1 (Oculus Audio 1.18). My test setup is really simple. A Media Texture, playing video with a Media Sound component attached on which the allow volume attenuation is set. Works perfectly on Rift but not on Go. Any idea what could cause this?

@mighty carbon 👏 that works. So volume attenuation does not work on Oculus Go with the new audio framework's Sound Component, only with "regular" sound sources.

Has anyone found a way to use vive controllers/trackers without the hmd? I just need the tracking portion of the system and would prefer to not be rendering to the headset and an external source
real needle
@wide flare You can try "EnableHMD" set to false on Begin Play, not sure if controllers are tracked at that point but worth a shot
I believe you need the HMD plugged in to initialize the runtime components of Open VR, but you can probably override that as well
In C++

sturdy coral
@wide flare I think there is a point where the engine looks to see if a headset is connected before starting steamvr though, not sure on that completely, I've never tried
wide flare
Will need to test but I believe that should be handled by steamvr, which is fine for now as long as I'm not rendering a full scene to the headset in theory
sturdy coral
I think you might need to tweak things in FSteamVRHMD::Startup() to call VR_Init as a non-scene application and not try and reference the compositor, but you can test and see if it works without doing that

if it got that far im unsure how much I'd be able to change most limitations I'm facing lately are in how steamvr was constructed and it not being open

@mystic cedar attach the gun to the socket; you can use the skeletal mesh editor of the hand to setup your socket placement, select the socket in the skeletal mesh preview and do 'attach preview mesh', and select your gun

then you can fine tune the placement

If I spread out assets on a large map instead of concentrated in one area, is this likely to help with performance?
Attempting to optimise this level (removed the PP and glass platform already)
olive garden
It will help if you have LODs and/or stop rendering assets when they get far away, but not otherwise.
Well, actually,
Having spread out assets will help a little because they won't all be on screen and be rendered at once, but don't rely on that, because if you ever get a vantage point where you see the whole area at once, it will essentially have the same performance as when they are close together.
I'm having a weird issue where when I package my game and use the -vr command line option or turn on "start in vr" in project settings, it doesn't track my location or controllers, the rotation tracking is seriously delayed, and Is Head Mounted Display Enabled node returns false.

You can render the widget on its own stereo layer and increase the layer's resolution, I believe

Stereo layer have issues though currently, hard to create an interacting laser that correctly overlaps it, doesn't currently support depth unless you are on rift, and until my pull request is merged in the rotations of them in SteamVR are wrong so you can't attach it to anything with a Roll element (wrist mounted, ect). Outside of that they are ok, though/

@sturdy coral I checked out what you linked me too and it does not have slide interaction. It has clips, but not slides.
wicked birch
@tired tree alright thank you.
sturdy coral
@median wedge ah I thought it did, I guess the slide just animates when it fires maybe?
@median wedge implementing a slide may be similar to the clips since they are both sliding along a track
I can't remember though if the clips just get sucked in or they slide in
I think there are also some slider ui handles in there that would be similar
can't remember if those are gripped or done with a laser pointer
median wedge
Either way its a collision, then an Automated Action. For my slides I have gotten the delta movement between the start and current grip, then converted it to a ratio and applied it to the animation blueprint. It causes it to look slow and laggy, and it does not keep up with the hand, partially because it is projected onto an infinite line on the weapon, and that changes, changing the amount of the slide that is pushed back.

@median wedge the basics of a slider are to have the current position and min / max positions, you track to the hand from its original point to the hand on grip and clamp to those min / max values
and yeah, my slider is not a good learning thing...its got a million features
its also using some tricks for multiplayer syncing
that aren't needed in single player
median wedge
Thank you for the help. So if I understand correctly you caluclate the delta from the initial grip, and then clamp it to the provided vectors, then apply that transform to the mesh?

yeah
just get the hands position on grip and track it on your boundries
really easy when you think about it

definitely a good deal, id say
it has 90% the power of a 2070, and like 70% of a 2080, so thats good on my eyes

people are mad that the 60 version is $350, but I think it occupies a new top spot in perf/$
wicked oak
@sturdy canyon you knew a lot about graphics rendering and stuff, no?
im tinkering with mesh shaders, and i dont know what to use for mesh data storage. Bindless textures, or a bigass massive SSBO with every mesh in the map
they are compute shaders that can output triangle lists, basically
sturdy canyon
I'm really really excited about mesh shaders, but no I haven't really looked into the implementation at all
Sculpting tools run way better with smaller chunks, but that increases draw calls
wicked oak
they are just compute shaders, pretty trivial
sturdy canyon
Mesh shaders will be my hero someday
wicked oak
you just read your mesh data from whatever the fuck you want, as long as you write into the "meshvertices" array
https://hastebin.com/komaperusa.cs this is how mine work @sturdy canyon
it just renders a triangle list, with a maximum of 32 triangles XD
sturdy canyon
This is just to get the hang of the syntax?
wicked oak
yes
this is like the absolute minimum
i want to make it proper, to render a mesh with more than 32 vertices
luckily there is a mesh optimization library that can generate the meshlets, but im thinking on how to architect the memory, becouse my goal is to be able to generate a "forest" with multiple grass types and tree types in 1 drawcall
an entire forest in one drawcall
sturdy canyon
Yeah that's a similar dream to mine: an entire sculpture with all its chunks in one draw call
possibly bad for perf to combine things too much, though
using it for a bunch of instanced geo seems more like its thing
I don't know if my dream is really what mesh shaders are meant for
yours seems right in line
mighty carbon
I guess I'll have to put 2060 on my wish list 😃
wicked oak
@sturdy canyon they render that entire asteroid field in 1 drawcall
tho its the same model with just tons of LODs
LODs and one model is the ez mode, for that is basically just mega-instancing
i want to try it for the "indirect on steroids" case, of rendering an entire scene in one drawcall, or just a few
sturdy canyon
Yeah combining 10 LoDs into one draw call is cool. But it should definitely be possible to combine many LoD'd meshes as well
wicked oak
as long as the pixel shader matches, you can
sturdy canyon
right, yeah
wicked oak
and for the pixel shader, you can use bindless textures
megashader OP XD
or just megatextures
sturdy canyon
as long as you aren't doing super weird procgen swirls or something on your plants
wicked oak
nah, just a megashader
same pixel shader on everything
and same wavey effect on all plants
so probably 2 drawcalls. One for the terrain, and one for plants
sturdy canyon
You can get surprisingly realistic looking moss with crazy shader magic and a quad

cunning depot
That's insane 😮
sturdy canyon
As far as I know you probably have to alloc a giant index buffer up front
wicked oak
@sturdy canyon that sure, but texture or buffer?
some bindless textures for mesh data, or a megabuffer with the entire world
megabuffer would work for the demo tho
but its not something i think can scale
nvidia seems to use textures in their demo
sturdy canyon
A texture array maybe and store the texture index in the verts
wicked oak
why in the verts? i was thinking of just having like 2 textures
one texture is XYZ pos + UV Y
and other texture XYZ normal + UV X
and use bindless
then i have a array of "mesh data" and an array of meshlets
sturdy canyon
ohh misread your code
I thought it was just returning an index array to an existing mesh buffer
wicked oak
at the moment im just doing 1-2-3-4-5-6
sturdy canyon
Errr vertex buffer
wicked oak
for indices
sturdy canyon
Yeah I see that now
wicked oak
but the indices would be stored in the meshlet array
so i would have a global array of all meshlets, or maybe use bindless texture again
ill go read the papers from nvidai xd
int vertexIndex = texelFetch(vertexIndexBuffer, meshlet.vertexBegin + v).x;
vec4 vertex = texelFetch(vertexBuffer, vertexIndex);
gl_MeshVerticesNV[v].gl_Position = transform * vertex;
}```they use textures
sturdy canyon
with high detail LoDs doesn't that spin a single thread for thousands of loop iterations?
wicked oak
why dont they have any example dammit
thats basically pseudocode
your meshlets should be small
like 32 or 64 vertices
and maybe 120 indices
sturdy canyon
ah okay. So then those high detail LoDs are broken up into hundreds or thousands of meshlets
wicked oak
yeah
each task shader invocation can spawn up to 64k mesh shaders
and each mesh shader is 1 meshlet
so the main idea is that you use 1 task shader invocation per mesh
and that spawns a bunch of meshlet tasks
imagine a 32k mesh
thats 5000 meshlets
so you have one task shader invocation (32 wavefront local size) cull them and pack them
but that only if you are doing it for a shitton of meshes at once
btw @sturdy canyon cool detail
you can do forward lighting at the meshlet level
instead of using an screenspace grid
and have like 4 pixel lights, hardcoded
and if you have more, just emit the meshlet twice
wicked oak
becouse its a compute shader, you could have the lights as an octree or whatever
sturdy canyon
right
wicked oak
keep in mind, branching would work fine
as the rasterizer is calculating the meshlet at once
wicked oak
octree lights is exactly the kind of thing i might do myself
XD
you could assign the lights by checking against the bounding sphere of the meshlet
if the bounding sphere intersects, render that light
sturdy canyon
yeah it shouuuld be pretty easy to pull off
dive through the lights tree until you've collected N effecting lights
or maybe dive all the way and pick the N brightest?
wicked oak
no, just effecting lights

as long as dev-rendering gets merged into 4.22
there
's a tiny chance it doesn't
although it's probably decided by now, so someone else may know better
wicked oak
ok, the first thing im going to try
is to render meshes though position arrayy on a texture
no indices nor meshlets
just 3 vertices per tri
sturdy canyon
how are you doing this, btw? Just a barebones C++ project?
wicked oak
luckily i have the code for the stanford dragon from my rasterizer XD
@sturdy canyon there is a random framework called Glitter wich is just a pre-set starter opengl tinker repo
with all the libs already setup, like glad, windowing, assimp, and glm
in a predone cmake
sturdy canyon
ah I didn't realize this stuff hit OpenGL yet
sturdy canyon
What's the oldest cards that support mesh shaders?
is it a software only thing so it goes back before 10xx?
could it conceivably run on a PS4?
sturdy canyon
ah
sturdy canyon
one more reason to be glad the 2060 exists
mighty carbon
lol
granite jacinth
Anyone buying that should be ashamed of themselves to being suckered into their BS
mighty carbon
between spending nearly $400 on 1070Ti and $350 on RTX 2060, why would you say 2060 is trash ?!
granite jacinth
?
You could have gotten a 1070ti for 350 weeks ago
with 8GB
And they have similar performance
mighty carbon
I didn't have $350 weeks ago
mighty carbon
and 2060 has that new VR port, plus a ton of VR optimizations
granite jacinth
I just don't get what they needed to shuffle up the names
It's a -70 series card called a 2060
(i mean, good strategy if they are making more money than last gen)
wicked oak
@sturdy canyon sending stuff to pixel shader its trivial
granite jacinth
I know what it has
wicked oak
just implemented vert colors
out Interpolant {
vec3 col;
vec2 uv;
} OUT[];
and the acompanying "in" in pixel shader as usual
cunning depot
What are these VR ports you speak of?
cunning depot
Interesting ty
Lowkey I just bought my Oculus rift a few days ago, do you guys think it's worth returning it (amazon so free) and buying the Oculus whatever that's gonna be coming soon, assuming the next VR headset from Oculus/HTC will be either the same or better in all ways ?
mighty carbon
Well, who knows when Rift S is coming and how much will that cost. But there will be no Gen 2 from Oculus until 2020 or even later
cunning depot
Alright ty, I'll stick with my Rift then 😃
mighty carbon
(and we don't even know what Rift S is going to have over Rift CV1)
cunning depot
Mhm
mighty carbon
I'd stay with Rift and get Quest when it comes out
cunning depot
👍
mighty carbon
especially that a few AAA titles are coming to Rift soon 😏
sullen vortex
guys has anybody used gameworks flex fluids in vr?
mighty carbon
jaunty shell
Oculus quest like stuff
sturdy coral
two on front and one on each side
mighty carbon
not whole a lot of buzz around Quest though.. My Twitter is all about Vive Pro Eye 😦
sturdy coral
seems like it so far
sturdy coral
ah nice
says gaming pc or desktop or phone (seemingly)
I hope it isn't just laggy wifi streaming or something
jaunty shell
😬
sturdy coral
controller looks almost exactly like quest controllers
jaunty shell
awesome controller design
yeah was about to say
that's a straight copypaste
well
was not expecting anything
mighty carbon
I am hyped for RTX 2060
and Quest
but I'd like to see more hype around Quest
especially about games for it
so far it's all the same OC5 stuff
sturdy coral
if cosmos does PC and mobile that is pretty big
they gave very few details but did mention that
cunning depot
So basically, as someone on a budget, I made a mistake buying a Rift this late in time considering there'll be better things sometime this year/next year 😭 Ofc I'll still stick with the Rift but I have learnt my lesson not to leave technology for a few years to stabilise because it'll always improve 😛
mighty carbon
Go can do PC with Virtual Desktop.. It's massive, but I don't think people care
granite jacinth
hmmm
mighty carbon
@cunning depot Vive Pro costs an arm and a leg, and lacks awesome games Rift offers.
but for enterprise, Vive Pro Eye + knuckles would be definitely better
wicked oak
that vive could be super interesting to experiment with foveated render tech
specially given that with VRS its easy as fuck to do properly
cunning depot
@mighty carbon Yeah lmao the deciding factor for me, even though HTC Vive was and is huge, is the fact I can literally get a top-end flagship phone at the price of the HTC Vive
cunning depot
Whereas Oculus Rift is like eh expensive but I can manage 😛
mighty carbon
btw, apparently Go doesn't require phone any longer.. But I can't really verify that
mighty carbon
also, what specs Cosmos has? FOV? panel? Sound?
granite jacinth
@mighty carbon huh?
Go only needs smartphone for setup
Actually, you can do it through PC emulator as well
Unless you mean they have done away with the requirement completely, which is nice.
@sturdy coral surprised no actual competitor to Quest was announced though
I wonder if this was a technical issue, or they didn't want to cannibalize Focus sales
Or if indeed the "phone" hint may play a hand in "competing" with Quest
sturdy coral
Quest is standalone or PC from the sound of it
granite jacinth
Ah
Well HTC is dying financially
So, it could be some tricky stuff to get people to buy their phones again
Although, they shouldn't have sold off their best division to Google then
mighty carbon
@granite jacinth I read somewhere that Go no longer requires phone to be activated and used. Don't know if it's true.
granite jacinth
Just got one for my kid over Christmas, still needs it
mighty carbon
also, Virtual Desktop allows you to work on PC via Go (requires 5Ghz router)
supposedly lag free even when playing pancake games on huge virtual screen
(you need kb and mouse to be connected to Go)
granite jacinth
imho, not "cutting the cord" is better for gamers
mighty carbon
I am guessing HTC is pumping out all this stuff to keep revenue flow coming
