Tried it and same error occurs..... Right now it's a pain in the ass to transfer hair from a static mesh to an animated one. The only method that is workign right now requires a lot of steps.
Also, if i import a alembic file (same vertex count, etc), if i don't put an edit poly above before copying the hair, all the hair orientation gets fucked up. Why is this happening? Our rig and animation is coming from Houdini, and we hoped that the workflow with Ornatrix would be pretty simple, but so far it isn't...
