Hello there,
Trying to save out ABC files of meshed particles with velocityPV from bifrost graph. Failing dismally, I'm afraid.
We need it to be an ABC of a polySurface in order to render with VRay. Motion blur is vital to the project
We were previously doing it with nParticles, which just does the velocityPV automatically when using the motionVectorColorSet attribute during export . Can't wrap my head around how to do this in bifrost graph though with bifrostGeoToMaya prior to ABC export.
Is there anyone who can advise me on the right approach here?
(says me, suspecting @syracoj is the man who knows everything)

Regarding:
"- should I add the motionVectorColorSet from the alembic export, or it is automatic if I just leave the tick on Write Color Sets options?"
I'm not sure off the top of my head. When you say Alembic Export are you refering to using the in-graph write_alembic node? It may work using that color set option. If it doesn't though, since you are passing the data to a Maya mesh via BifrostGeoToMaya you could use Maya's Alembic and see if it's 'write color sets' data works. Either way, try it and see what happens.
Glad to hear you are unblocked.
Yes I was referring the Maya alembic exporter, I already tested it (see prev. post) and it's working. The multiplier for the mb length also is working. The in graph exporter doesn't the same way though.
