Hey, I have couple questions regarding exporting primitives to an alembic cache. I'm losing my primitive's color assignment when I export. I've tried moving Cd from point to prim. Unpacking after reading in the cache. Nothing seems to work. The scene is super simple, packed Polygon sphere copied onto 25000 points with a random color assignments. How can I preserve the color attribute? If I unpack before exporting, the color reads in. Not what I want to do though.

The other question I have, loading the cache is very slow. The file size is nice and small, but it takes quite a while for houdini to work with it. Any tricks for speeding that up?

Much thanks!

I second this question. How can I make sure my “prim attrs” (Cd) is exported in my alembic so that information can be read & utilized in another 3D package?

I don't think you can save attributes on packed primitives to alembic cache. They need to be on the actual primitives/points/vertices.
