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

andybakOP•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"

andybakOP•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

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

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

andybakOP•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

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

andybakOP•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

andybakOP•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

andybakOP•11/19/21, 2:21 PM

(the split by strokes bit)

andybakOP•11/19/21, 2:21 PM

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!

andybakOP•11/19/21, 2:22 PM

do the exported meshes use submeshes? i guess not

andybakOP•11/19/21, 2:22 PM

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

andybakOP•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!

andybakOP•11/19/21, 2:23 PM

especially as you can script/automate blender quite easily.

chard•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

andybakOP•11/19/21, 2:24 PM

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

andybakOP•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!!

andybakOP•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!

andybakOP•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.

andybakOP•11/27/21, 4:19 PM

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

andybakOP•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

andybakOP•11/27/21, 5:38 PM

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

andybakOP•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
