Well the question lives between blender and max community so I need to ask here just in case somebody also knows the answer.
When exporting objects ( a cube ) with different 3 materials assigned to the faces from Blender in Alembic, once I import in MAX the Material IDs goes nonsense.
I even tried with Vray proxy, and also happened the same.
Then I read the documentation of Alembic and also noticed that we had some troubles also from Houdini to Max.
Alembic won't write the Material IDs by default and we had to force it in Houdini so MAX understands that. We could find a workaround for Houdini. but I'm a bit stuck with the Blender 3DsMax connection.
By the way FBX works fine, but the implementation for references feels not so clean, and we were hoping to be able to use ABC for the neat reference upgrade.
Anyone knows something about it? is there another ABC exporter for Blender that speaks MAX better?
