hey all, I'm experimenting with file layering.. eg. save out a static base file (UVs, etc) and save a second deformation file (animated positions, normals, etc).


In SOPs, I think I understand the workflow for generating the static (and sparse-data deformation) ABC/USDC files. However, when I read the resulting files in, I'm not sure I understand how to combine the files correctly.

questions:
1) In SOPs, Alembic Read has a layering multiparm, but the USD File Import Does not. Is there a way to apply the deformation_layer.usdc to the static.usdc in SOPs?

2) In LOPs I'm not sure if I'm doing this correctly, but chaining USDC sublayers seems to work. If I do the same for ABC, the SceneView is empty (which indicates we're losing the static USDC prim)

Any suggestions? thanks!
