I’m writing here for help as I can’t wrap my head around how the motion blur integration for the alembics is functioning on Blender. I basically export a geometry with v attribute from Houdini, but I can’t use that to generate motion blur on Cycles, it simply refuses to do it.
I tried everything -
Exporting v on the points or on the vertex before in my alembic doesn’t change a thing.
Setup the meshSequenceCache modifier properly with v attribute set, in seconds or Frame it doesn’t care and simply does not apply it, whatever my v attribute being on the points or the vertex.
If anyone managed to make motion blur work with an attribute from Houdini I’m super interested, I tried so many tricks on various forums already and I’m a bit desperate to make it work.
