Hi. Thank you very much for this. I had an alembic from a long time ago that I could never use attributes of (I thought they were never exported), with this patch now I know they were all saved and can be used!!!. I really don’t remember the export process anymore so I’ll do more tests when I relearn it, meanwhile I experimented with my old alembic (Velocity, Cd, Age attributes and a custom one for ID were recognized) using geonodes
