I'm running into this as well in 3.08.3 Standalone when exporting an .obj from Maya.
I've tried deleting the unnecessary materials from the .mtl text file.
Tried deleting the entire .mtl file
Tried deleting all of the extraneous materials in my Maya scene
Tried exporting with materials unchecked
Tried exporting with just face sets
None of which worked for me.
I have come across something odd. If I export the obj with all options set to off, no Groups, no Point Groups, no Materials, no Smoothing, no Normals and overwrite or leave the name exactly the same as the original obj with unnecessary materials, it still exports with all of the unneeded materials, or the .mtl file isn't being overwritten.
Now, if I change the file name to something like test.obj on export with all of the same options listed above, the obj will import into Octane with only one input (none of my materials). If I turn materials on during export and overwrite the same file (test.obj), still only one input... it's just called Diffuse Material.
Next, I exported another obj called test2.obj with only Materials enabled during export. All of the materials including the unnecessary materials show up again in Octane.
Finally I deleted all of the extra materials in my Maya scene and called the obj test3.obj. It then imported with the correct materials, kind of. It still brought in the initialShading group node, which Maya won't let me delete.
Needless to say, this is far from an ideal workflow.
I've only recently started using octane over the past few months and I was hoping this was just an isolated incident or two, but it's starting to do my head in. I've kind of just been putting up with it, chalking it up to lack of experience with the software. Alternately I've tried alembic, but Maya won't let me overwrite the .abc file while it's open in Octane. I'm also getting weird scale issues with Alembic, even with World Space option on during export. Obj is usually the tried and true method, so it would be nice to get that working smoothly.
I hope that makes sense. Any help would be much appreciated. Thanks!
