Curves to Alembic problems

Blender Version
Broken: 2.80 a6b2ec0bc231

Short description of error
When exporting and importing curves to alembic, certain errors appear. Here is an example file.


Export the curves as alembic and when importing them into a file this happens as far as I can tell:

  • The curve loses its Geometry settings. In the example file the curves have depth and a full Fill Mode to them but once imported they switch back to the default settings of newly created curves.
  • The curve type is switched to paths instead of bezier.
  • Separate curves within the same object are being connected randomly. This apparently also results in some far stretched curves in comparison to the original.

I think the best solution for the studio right now would be to have the option to export curves as meshes like already mentioned here: T51311

Those issues can only be solved by figuring out how to store those settings in Alembic in a way that other software understands it as well.

Can you attach before & after images, so that I know what you're looking at?

I think that's a doable approach. That way we circumvent the unknowns I describe above.
