Hi Nick, materials should come through to C4D using OBJ format.

Did you possibly disable the settings in MoI for "Write material assignments" or "Write .mtl file" ? Those are checkboxes under Options > Import/Export .

Is an .mtl file being created?

What about any import settings in C4D, have you checked there to make sure importing materials is not disabled there?

If you're using an older version of C4D I seem to remember that the built in OBJ importer wouldn't read in the material color but would get the material list and assignments ok.

Im not sure what was wrong, but it worked when I pasted the same model into another file and then exported again.

Thanks for the help though Michael! As always :)
