I’m sorry I should have included this to start with. I’m on windows 10 with a valve index, everything works perfectly fine. I can’t talk a screenshot right now but I can upload one later. Its just black but I can see and move around the controllers I just can do anything. I see the initial steamvr logo on opening it up but that’s it. It just goes black

No Open Brush logo or anything else visible (apart from controllers)

I would like to recreate some of the animated brushes in GLTF: how feasible would that be? Do you have any pointers?

For example the "fire" brush

@mikesky don't we already have UV and vertex animation in our gltfs? Assuming the viewer app does the right thing?

mikesky•11/9/21, 12:05 PM

Yup! it needs to specifically be updated in whatever renderer system you're using, see the example in three-tiltloader readme https://github.com/icosa-gallery/three-tiltloader

I'm generally exporting to Sketchfab, would it work there?

mikesky•11/9/21, 12:06 PM

Nope

mikesky•11/9/21, 12:06 PM

They don't have the bandwidth to add proper support

mikesky•11/9/21, 12:06 PM

We kinda did all of the legwork they need though

NNLR I'm generally exporting to Sketchfab, would it work there?

andybak•11/9/21, 12:08 PM

Yeah. So nag them. We've offered to help and like mike says - most of the work is done.

NLR•11/9/21, 12:09 PM

Can I use the tiltloader and then upload the GLTF file to Sketchfab?

andybak•11/9/21, 12:09 PM

The loader needs to be hosted by them. They need to integrate it.

NLR•11/9/21, 12:15 PM

fffaack

NLR•11/9/21, 12:15 PM

do some other platforms/games have this loader?

mikesky•11/9/21, 12:21 PM

Icosa does naturally, and it’s there for others if they need it, we also have a template repo if it’s just a stanalone thing, I’ve used it on hic et nunc for example

NLR•11/9/21, 12:23 PM

Will we be able to export to Icosa at some point?

mikesky•11/9/21, 12:29 PM

Yes, you can manually do it now if you feel like it! Export from open brush, then upload via the web interface

NLR•11/9/21, 12:32 PM

My problem is that I want people to be able to use the stuff I make (here wearables) on other platforms. So far it looks nothing can really be exported out of open brush..

NLR•11/9/21, 12:34 PM

This is supposed to be the "double tapered marker" but I don't know how to fix it

mikesky•11/9/21, 12:35 PM

Everything can be exported, it’s just so special

that no one has really tried to support it before, I’d say we’re the first ones putting this code out there

mikesky•11/9/21, 12:36 PM

Making a GLTF extension is the most natural way for others to support it, so we’ll be looking at formalising that too

NLR•11/9/21, 12:37 PM

as of right now is there something I can do to have tilts working in any standard format?

mikesky•11/9/21, 12:39 PM

Only things built in unity specifically including the tilt brush toolkit will support it

mikesky•11/9/21, 12:39 PM

I think VRchat might but that’s not at runtime

NLR•11/9/21, 12:42 PM

how realistic is it that open brushes will be able to one day work on other platforms?

mikesky•11/9/21, 12:43 PM

Very, and that’s what we intend to push for with this community

mikesky•11/9/21, 12:44 PM

What programs and platforms are you thinking of specifically?

NLR•11/9/21, 12:44 PM

all

NLR•11/9/21, 12:45 PM

I want to make things "for the Metaverse". So either I can export to a globally supported format, or it does not really work for me

NLR•11/9/21, 12:45 PM

Your plan is currently to try to push every single new platform that will be created to do a bunch of work to include the openbrush SDK?

mikesky•11/9/21, 12:48 PM

GLTF is going to be the format for that for sure. Open brush will probably need some form of extension for it’s more special brushes for sure, but you can make that ridiculously easy for platform implementers, lemme get an example

mikesky•11/9/21, 12:50 PM

https://github.com/mozilla/hubs/pull/4741/files here’s an extension by the open metaverse group being added to Mozilla hubs

Hey Hubs team

long time no see! I'd like to get support for something we've been working on in OMI working in Hubs.

mikesky•11/9/21, 12:50 PM

SDK built once, only a few lines of code to add (and this is having to jump through hub’s much more complicated system so the base case is even easier)

NLR•11/9/21, 12:52 PM

So I'm thinking:
VRChat
Facebook horizons
Somnium Space
OVR
Decentraland
and more

NLR•11/9/21, 12:54 PM

In the meantime is there a way to fix the double tapered marker on Sketchfab? I did not think that this brush would give me problems

mikesky•11/9/21, 1:02 PM

That sort of support will rely on the closed platforms being happy about accepting open standards, and users pushing for it. For example VR chat has to be processed in unity and uploaded as unity’s proprietary format. It does happen to support the tilt brush toolkit though. No GLTF runtime support at all. If you’re interested in wearables then the platforms should be considering VRM avatars, which again is implemented as a GLTF extension.

mikesky•11/9/21, 1:03 PM

I can’t comment about Sketchfab support I’m afraid, not looked at it a lot (after they didn’t have time for us)

NNLR So I'm thinking: VRChat Facebook horizons Somnium Space OVR Decentraland and mor...

andybak•11/9/21, 1:57 PM

In a lot of these cases, we need these platforms to talk to us, or at least respond if we contact them. That's often the tricky part.

annahoo.•11/9/21, 7:43 PM

New to discord, having an issue I can't solve with OB. This first screenshot is from the apps camera that I used in this painting a year or so ago. The foreground and background strokes are blurred, but there is no blurred vignette. I have since gone back into the same painting and tried to take photos, but there is no blurring effect at all. Was this in an update to the app?

Kind of a circular problem. Once the tools are built, and a community starts to really take shape, art blitz them on twitter.
Going to have a hard time pushing for integration until there's something fully defined that they can look at and go, ya, worth doing

andybak•11/10/21, 10:01 AM

"A year or so ago" would have been before Open Brush was released. So - did you take this screenshot in Tilt Brush? Our first release was in January this year.

andybak•11/10/21, 10:02 AM

If it was Tilt Brush, then it's a bunch of stuff was changed by Google to make it possible to release as open source and it's hard to track down all those differences. If you just mean "I used an earlier version of Open Brush" then I might be able to dig a bit deeper to see what changed.

annahoo.•11/10/21, 5:49 PM

It was 100% open brush as my painting is still in there, and I've taken screenshots within the OB app since and they don't look similar, everything is in focus.

andybak•11/10/21, 7:01 PM

I'm a bit stumped. We've never had a depth of field effect. The 1.0 release didn't have bloom but it was then fixed. Multibrush had more effects but you're certain it was Open Brush... The only effects I'm aware that we've ever had is Bloom and Vignetting. I guess bloom could be mistaken for a depth of field blur - but it responds to brightness - not distance between the brush-stroke and the camera.

Uki Maru•11/10/21, 10:54 PM

In the experimental build, I see that the pictures taken do have a depth of field like effect. @annahoo. is this the kind of blur you are talking about?

annahoo.•11/10/21, 10:58 PM

Definitely not vignette because I customized the config file specifically to get rid of that (and have been able to toggle it back on and check to make sure it's not the effect I'm looking for). I haven't downloaded multibrush either. That might be the effect, I'm not sure, I've got another photo take in app of the same painting, different angle that might also show the effect better

annahoo.•11/10/21, 10:58 PM

it doesn't appear to be color related

Screen_Shot_2021-10-27_at_3.40.13_PM.png

annahoo.•11/10/21, 11:01 PM

where as now, same painting in OB, the background/foreground blur isn't happening.
