Philipp Oeser (lichtwerk) placed T87351: Alembic Exports Particles Wrong? up for grabs.

That being said, we could add a check in should_visit_dupli_objectfor dupli_object->particle_system, but since the intentions are unclear, I would rather have @Sybren A. Stüvel (sybren) comment on this.

Philipp Oeser (lichtwerk) added a comment to T87351: Alembic Exports Particles Wrong?.

If the system is set to render as object, yes, those duplis should be exported. If the system is set to Halo, then only points.

Afaict, those duplis actually should not be exported at all.
Particle export should be animated points, thats it.

Vertex interpolation option introduced in rBbab2260b59c7: Fix T71981: Alembic vertex interpolation can jumble mesh was defaulting to ON (correct) in that commit, but was lost in rB83980506957c: Use DNA defaults system for modifiers
So if you have a file that was (incorrectly) imported with a version after rB83980506957c you'll have to enable Vertex Interpolation option on every MeshSequenceCache modifier by hand.

To speed up the the triaging process as much as possible, it would be good to have a minimal example case with just one source instance (duplicated a couple of times) to reduce complexity.
In the meantime, we would at least need the source .blend file (where the .abc was exported from).
This ensures we are all on the same page and reduces setup time if multiple devs are looking at this.

LGTM

Not sure why you added @Sybren A. Stüvel (sybren) as reviewer here though? AFAIK he is neither UI nor Modifier team member?

This is because it changes the enum used in the alembic exporter [which was wrong I think]
