Short description of error
When importing alembic with varying vertex count, normals on object appear to be always flat, whether reading them from alembic or smoothing them manually (autosmooth)
Exact steps for others to reproduce the error
- Import alembic with varying vertex count (see attached abc file, )
- Try to smoothing objects normals, disable "face" in alembic modifier and enable autosmooth.
- Normals either will be always flat, or will be smoothed only at first frame.
