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

chardOP•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?

andybak•11/19/21, 2:23 PM

at a certain point we have to accept we're not a mesh editing program and that "just use blender" is a valid workflow!

andybak•11/19/21, 2:23 PM

especially as you can script/automate blender quite easily.

chardOP•11/19/21, 2:23 PM

Yeah it's very common among all 3d packages, just trying to not jump into blender every time because I'm also iterating on the original scenes

andybak•11/19/21, 2:24 PM

someone wrote a cool unity extension that allowed you to call blender commands from within the unity editor

andybak•11/19/21, 2:24 PM

it basically exported the mesh, called some blender python and reimported the mesh. it was quite extensible as well

If i export an object (eg an animal) piece by piece, but don’t move it, when I import all the pieces into unity, will they automatically reassemble themselves? As in they will be in the same position as when I exported them so i don’t have to try and reassemble them in unity (which I find too hard) - thank you!!

andybak•11/27/21, 12:26 AM

Why are you exporting piece by piece? Is it because you want to split the mesh in Unity? There might be better ways to do that.

Ozymandias•11/27/21, 1:20 AM

i think so because otherwise i have to make sure i use diff brushes for all the different parts i wanna move? thanks

Ozymandias•11/27/21, 1:20 AM

ah ok

Ozymandias•11/27/21, 1:20 AM

so its not efficient basically

Ozymandias•11/27/21, 1:21 AM

what would be a better way pls? thank you!

OOzymandias what would be a better way pls? thank you!

andybak•11/27/21, 4:18 PM

hmmmm. we did do a bit of work on allow exports to split every stroke into a different mesh but it didn't get finished.

andybak•11/27/21, 4:19 PM

however - it's fairly easy to do that via Blender or Probuilder

andybak•11/27/21, 4:19 PM

Do groups get preserved on export? that might be a good compromise.

Ozymandias•11/27/21, 4:20 PM

sorry theres a way to group strokes together whilst in open brush?

Ozymandias•11/27/21, 4:20 PM

i did not know

Ozymandias•11/27/21, 4:20 PM

thanks!

Toggle Grouping for Selection

Combines the currently selected strokes into a single group. They will move and scale as one. You can ungroup them easily by clicking again.

Ozymandias•11/27/21, 4:25 PM

ohhh ive done this, did not imagine it would stay glued together after the export

Ozymandias•11/27/21, 4:25 PM

i dont think it does personally

Ozymandias•11/27/21, 4:25 PM

but not sure ive 'toggled'

Ozymandias•11/27/21, 4:25 PM

will try it out

Ozymandias•11/27/21, 4:25 PM

thank you!

Ozymandias•11/27/21, 4:27 PM

(im not currently working on this btw have sort of resigned self to not splitting the mesh but will be so cool if i can work out how to :D)

OOzymandias i dont think it does personally

andybak•11/27/21, 5:38 PM

No - I wasn't sure it did. I was asking.

andybak•11/27/21, 5:38 PM

But it would probably be a good feature to implement.

Ozymandias•11/27/21, 5:41 PM

it would be so awesome!!!!!!

Ozymandias•11/27/21, 5:41 PM

wow

Ozymandias•11/27/21, 5:42 PM

1pld•11/29/21, 5:00 AM

I believe groups export as different pieces

1pld•11/29/21, 5:01 AM

If they don't, it would be a nice feature

Has anyone else had a problem building for quest 2 where when they export the APK using the guide on the openbrush GitHub for quest 2 that the build is a folder rather than an APK file?

Does anyone know how to make the APK from the folder?

I tried installing Android studio.

I was wondering if maybe it's because I didn't approve the connection request inside the headset before building?

Generally I've not had a problem with making Android builds the regulsr way

mikeage•11/29/21, 4:25 PM

The build should have an APK inside it... what do you see there?

I'm seeing basically what looks like an unzipped APK

You build via the GUI Tilt->Build (or something like that)? And the output was in

../builds/Release_OpenBrush_FromGui

../builds/Release_OpenBrush_FromGui

or something (i forgot the exact details but it should be something similar)?

chardOP•11/29/21, 4:29 PM

Yep

chardOP•11/29/21, 4:29 PM

Sorry I didn't see any documentation for this part

Cchard Yep

mikeage•11/29/21, 4:30 PM

that is... strange. It'd take me 2 hours to reproduce because I recently wiped my local Library folder, but it should have some JSONs (unneeded) and an APK. Are the files you're seeing in the root, or a subdirectory? Can you paste a screenshot or directory listing?

chardOP•11/29/21, 4:30 PM

mikeage•11/29/21, 4:32 PM

ok, great! We'll continue later.

This is the only documentation we really have https://github.com/icosa-gallery/open-brush#building-your-app-for-oculus-quest

What do you mean by "export the APK using the guide"? What's the export?

chardOP•11/29/21, 4:40 PM

That's the one, yeah sorry I just meant do a build rather than export

chardOP•11/29/21, 4:40 PM

Following those exact steps there
