Hello there !

So, I'm currently working out how to add a fur system to an animated alembic file imported (animated in) Maya. This is to debunk the workflow we'll be using on my graduation project, and all rigging and animation will be done on Maya, but grooming (including sim) on Houdini.

So far, I've got a basic boucing sphere to test things out exported from Maya both as a simple .OBJ geo, and as an animated .abc (alembic) cache.
The setup seems to be “working”, but somehow, the hairgen seems to generate on each individual faces of the animated sphere, when it doesn't on the static mesh.

Is there anything specific that needs to be done in order to apply properly the deformation and sim nodes to an alembic ?

Any tips, ideas or suggestion would be greatly appreciated ! Thanks.

Hey risola.

Normally you have to unpack alembic geometry before you can use most of the Houdini nodes.

You can do that by just using an ‘unpack’ node.


Are you using the Shelf tools to generate the hair or do you build the system from scratch?
