Lots to play with there. What does frame delay do?
Is that the time between frames, allocated processing time per frame, something else?

AncientWorldsOP•11/8/21, 11:25 AM

Guess it's a starting point for documenting the individual options, just particularly curious about that one

andybak•11/8/21, 11:25 AM

frame delay seems to be "time between generated frames" - so essentially the frame rate

andybak•11/8/21, 11:25 AM

0.05 = 20fps

andybak•11/8/21, 11:26 AM

but - i haven't actually tried it - so let me know what you discover

AncientWorldsOP•11/8/21, 11:27 AM

Ya, not even sure which way it scales. I'll spend a day playing with those settings, probably the next thing I want to dive into

AncientWorldsOP•11/8/21, 11:27 AM

will comment in the documentation thread as I figure it out

fps = 1/"frame delay"

So - would recording what you see in your headset work? Because the Quest does that natively.

Could someone help me out, both open and tilt brush launch into a black screen. i can see my controllers but i cant do anything. What can i do to fix this?

andybak•11/9/21, 10:05 AM

We might need a bit more info!

What headset? Standalone Quest or a PC headset (if so which one)?
Do other VR apps work correctly?
Can you take a screenshot of the controllers? Is the screen completely black?
Do you see the logo when it's opening up? Does Tilt Brush show the intro sketch?

andybak•11/9/21, 10:37 AM

OK. So I drew a rough square for reference

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

andybak•11/9/21, 12:03 PM

@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

mikesky•11/9/21, 12:06 PM

https://github.com/icosa-gallery/three-tiltloader/blob/main/src/helpers.ts#L23

NLR•11/9/21, 12:06 PM

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

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.
