Hey everyone. I have a mesh in 3DS max using a multi sub-object material, and corresponding material IDs. After exporting to FBX and then importing into Houdini I'm struggling to find the material ID information.

How do I use Houdini to read and assign material ID information that can be read between packages?

It depends a bit on how you import the fbx
1 - File import fbx
2 – Geo/File nodes

With Method 1 you get a Subnetwork with materials + groups(with the material path)
With method 2 you only get the mesh with the attributes

The material IDs are converted into groups
