3dsmax MultiSub Object material to Houdini


Recommended Posts

Hello,
Im a 3dsmax user and Im sending the assets I model to an artist that uses Houdini.

My meshes had different materials on it, each one with a MatID
I export my meshes in alembic, and I export my Arnold shaders in a .ass file both opens without problems in Houdini

When exporting my shader from max, to make it compatible with Arnold shaders, the MultiSub Object is transformed to a Switch_Shader material, and in the index the input data is controlled by the matID. This works perfectly in max, but my problems are in Houdini because doesnt understand the matID data

The arnold shader when imported to Houdini, creates the Switch Shader, and the other is the material for the index, that is loaded with a fetch
