Thanks, but I want to build it on my local machine in order to be able to change something in code.

Thanks, but I want to build it on my local machine in order to be able to change something in code. I'm currently studying different existing libraries for oculus. This is one of libraries I want to study and maybe integrate somehow in my project

nike61OP•11/19/21, 1:17 PM

Btw, is there any other exitsting games or projects that is built on top of open brush?

Yes - the workflow is: 1. fork our repo 2. Turn on Github actions on your fork 3. Push a change with "[CI BUILD]" in the commit message. Then Github automatically does a build for every platform

Well there's all the stuff mentioned in the docs: https://docs.openbrush.app/alternate-and-experimental-builds/

Pre-release, Alternate, and Experimental Builds

But there's probably more. I always keep an eye on the Github network graph: https://github.com/icosa-gallery/open-brush/network

But that doesn't catch stuff that isn't public, isn't a direct fork - or stuff on Gitlab etc.

nike61OP•11/19/21, 1:21 PM

Yes, right

mikesky•11/19/21, 1:21 PM

okay, that's two for the list of libopenbrush

mikesky•11/19/21, 1:22 PM

the current codebase is very intertwined, but in the future we want to make the core of it a module that anyone can use, with a nice API

mikesky•11/19/21, 1:22 PM

by the way, if you just want to display things that are created in open brush, there's a separate toolkit for that

That would be great!

Nnike61 That would be great!

andybak•11/19/21, 1:31 PM

It might be possible to build something on top of Open Brush. What's tricky is extracting smaller parts of it. Have you looked at the API stuff? That is a good guide to how to activate specific bits of functionality outside of the main UI

nike61OP•11/19/21, 1:35 PM

Not yet, but I'm going to look at API once I fix my environment

andybak•11/19/21, 1:38 PM

That stuff is hopefully going to be merged to main fairly soon: https://github.com/icosa-gallery/open-brush/pull/198

@andybak I just started playing with the "save selected strokes" & media library tools.
The unity scene that results when brought in via GLB doesn't contain the referenced models (they're just empty).
And the files that it spits out into the Media Library folder are .usd, which, I'm not sure if it's supported by the toolkit.

Let me know if you think this should work in theory, or if i'm barking up the wrong tree.

I'm going to see if there's a USD plugin I need in order to pull in the models first

andybak•11/19/21, 2:03 PM

doh! i knew something felt wrong as i typed that

The tools, if they were to work would be SO handy

andybak•11/19/21, 2:03 PM

i think nobody thought of using those two features at the same time

andybak•11/19/21, 2:04 PM

personally - i would like to replace the "save selected strokes" with a more flexible approach. at the moment the strokes become non-editable (coz they are .usd files)

andybak•11/19/21, 2:04 PM

I'd rather get scene merging/additive loading working

andybak•11/19/21, 2:05 PM

and that is actually nearly done (but might have subtle bugs)

Aandybak I'd rather get scene merging/additive loading working

chard•11/19/21, 2:05 PM

yeah that'd be ideal

chard•11/19/21, 2:06 PM

In the meantime I can export each of my models as GLB and recombine it in unity using the Nulls as transform guides

andybak•11/19/21, 2:06 PM

i keep meaning to get back to the scene merging. if i'm lucky i might even have a build today. assuming my last fix worked

andybak•11/19/21, 2:07 PM

(so - now I've jinxed it obviously!)

chard•11/19/21, 2:14 PM

Maybe scene merging will skyrocket the scene complexity as well though?

chard•11/19/21, 2:14 PM

It sounds cool, I would use it today if I could

Cchard Maybe scene merging will skyrocket the scene complexity as well though?

andybak•11/19/21, 2:14 PM

One of the things I'm stuck on is updating the tilt meter correctly

andybak•11/19/21, 2:15 PM

but there's also a note in the code from ages back saying "additive loading is buggy as it duplicates existing strokes" - i can't seem to see any evidence of that but i haven't tried too hard

andybak•11/19/21, 2:16 PM

i think even with bugs it's quite appealing. it might be "bearably buggy" and we can hide it behind a settings flag so normal users don't get tripped up by it

chard•11/19/21, 2:16 PM

I love reading all the little notes, it's like "this'd be a really cool feature if I ever got around to it"

andybak•11/19/21, 2:16 PM

yeah. check out the comments in the .tilt file loader. it's practically a history of development quirks and decisions

Aandybak but there's also a note in the code from ages back saying "additive loading is b...

chard•11/19/21, 2:17 PM

It's tricky that there's no way to tell if it was fixed and then that note wasn't deleted

andybak•11/19/21, 2:18 PM

I tried a couple of ways to detect the extra strokes - but couldn't.

andybak•11/19/21, 2:18 PM

they weren't there on export, didn't seem to be in the unity scene. but i might have done something dumb

kinda makes you sad to think this code existed at some point but we won't ever get to see it

chard•11/19/21, 2:19 PM

It's not a huge problem, as long as the merged thing has a unique parent in the hierarchy from the original

andybak•11/19/21, 2:19 PM

I'd pay good money for a chance to look through the internal Google repo branches!

chard•11/19/21, 2:20 PM

Grouping and the breaking by colour tools in toolkit have been saving my life

chard•11/19/21, 2:20 PM

I just need something which breaks apart by individual strokes.
And one which resets the pivot of the group to the centroid, or the centroid + minimum bounds on the Y

andybak•11/19/21, 2:21 PM

i think someone did that once - i had a go at it and it didn't seem that hard

andybak•11/19/21, 2:21 PM

(the split by strokes bit)

andybak•11/19/21, 2:21 PM

there's one place in the code where it decides how to split meshes on export

Aandybak there's one place in the code where it decides how to split meshes on export

chard•11/19/21, 2:22 PM

Ye I was playing with that, didn't get around to split strokes though, if it exists I'll take it!

andybak•11/19/21, 2:22 PM

do the exported meshes use submeshes? i guess not

andybak•11/19/21, 2:22 PM

blender must have a "split mesh into non-connected parts" feature?
