Hi,

in houdini I have a meshed liquid sim. Now I'd like to transfer this to maya with attributes like velocity and maybe some other attributes like density or vorticity.

I can simply convert the velocity to color which is then transferred by the houdini engine to a vertexColor map. But how can I add other attributes and maybe create a secondary vertexColor map?

Unfortunately, you can't output more than one colorset per mesh right now. It's a frequently requested feature, but I haven't had a chance to get to it yet. And there isn't really a good workaround at the moment. Depending on how heavy your mesh is, maybe you can output a second copy of the mesh with the other colors that you want?

Thanks. We render with Arnold, so first I'll try to compile the Arnold alembic procedural for maya. Maybe this solves our problems at the moment.

here hoping there is an update on the topic of multiple sets of anything? maybe even a tentative date… ?
