Alembic export does not export smoothing groups
Closed, ResolvedPublic

Description

Operating system: Windows 10

Blender Version
Broken: 2.8 latest master

Short description of error
In many (majority) of cases, Blender's .abc exporter doesn't properly export smoothing groups.

This is the exported model:

The exporter settings are explicitly configured to export all the face shading properties and normals:

The same model reimported into same version of blender using the same .abc file that was exported:

Exact steps for others to reproduce the error
1, Open the file:


2, Export it as .abc format. Make sure to enable all the options related to normal export
3, Import the exported file back to blender.

Result:
Face normals are gone

Expected:
Face normals are preserved

UPDATE: It appears that GLTF format has the same problem.

This seems like a feature request... Just kidding ;)

I can reproduce this issue on my end too. It seems like (the final) face normals are indeed not preserved.

Thanks for taking the time to look into it :)
