Hi folks!

Is it possible to apply an alembic file which doesn't contain the geometry but only the point motion to an object in Houdini, similar to what you can do with Crate in Softimage?

I like it because the .abc's become quite light.

Cheers!

Yes, it is possible. Given that your mesh and the cached points match up. You can safely use ‘Attribute Transfer’ SOP for this. Transfer P from the Alembic SOP to your Mesh.

If the point count and order match up, probably cheaper to use an AttribCopy.

Yes, of course. Attribute Copy is the correct one.

Great! I'll do some experimenting.
