Material IDs in almbic file

[Mnietek2707]

Houdini geo (mixed geo and packed geo) with prim groups _00, _01, etc. -> exported to alembic -> imported to max as vray proxy

Packed geos have wrong material id's in max.

When I import alembic through regular max importer everything is ok.

Houodini:


Max:

Try one of the latest stable builds.
This works fine on my side:

The handles and the rear boxes should have different material IDs. In your screenshot they have the same ID. Its wrong.

EDIT: nvm me. max imports it correctly.

Left, First max import.
Middle, V-Ray proxy import
Right, Second max import.

If i inspect the mesh with the max importer, i see the exact same structure as i see when i do so with the proxy, and *four* IDs, from 0 to 3.
Something isn't quite right in how that cache works with Max (leftmost has 5 ids, and is taking the fifth material from nowhere at all.), and as a corollary with us.
