Hi,

I have to process (cleaning up) some alembic animated mesh exported from Maya which has a hierarchy.

I am using the Alembic SOP to bring in the file.

When I am done, I am writing out the files via ROP Alembic SOP

(1) I noticed that the files becomes very large (compare to the original input file)
(2) The hierarchy is gone, replaced by names like alembic1_NNN

What Alembic output approach should I use instead to keep the file size in check and also to preserve the hierarchy ?

Cheers
