alright, that looks good, lets add a test then :)

You are modifying libf3d public API! ⚠️Please update bindings accordingly⚠️!
You can find them in their respective directories: c, python, java, webassembly.

\ci full

[mwestphal]

Still working on this @LuTheDog ?

[LuTheDog]

I was, but I've been having less and less free time. It's mostly done, but one of the tests fails because of a slowdown, which needs to be debugged.

[mwestphal]

Can you provide steps to reproduce the issue ?

[LuTheDog]

Just running the ci tests does it, locally or remotely

Are you talking about this failure ?

?

[LuTheDog]

Exactly

[mwestphal]

@LuTheDog it doesnt fails because of a slowdown, it fails because, with your changes, the animation is not recovered correctly anymore.

./bin/f3d "/home/glow/dev/f3d/f3d/src/testing/data/xform_anim.abc" --verbose

Without your changes:

...
Animation(s) available are:
0: default

With your changes:

...
No animation available

So it looks like more work needed im afraid.
