Hi there, Alembic Particle export has been a feature that was requested for a while and so we’re running into the same limitations of not knowing how other software want to treat these particles. I’ve provided the attribute names that alembic files tend to look for, but I wonder if the alembic particle ID gets reset once the lifetime passes.
Attribute names:
P (positions)
.pointIds
.velocities
.arbGeomParams contains
texture (colors)
density
age
size
If you have a video of the particle bouncing randomly that would be great to see what you mean. I am not sure what would be causing that. I’m also not sure about the instance index changing randomly, can you point out what you mean with that?
It would be great to work with you to get a solidified workflow for importing alembic particles into Blender. Their documentation is kind of poor, but Blender works so well for most other cases. Looking forward to hearing from you!
