Connecting .mtl files in Notch

I exported an .obj out of Blender and it was split up into a .obj and a .mtl file, like .objs always are out of Blender. When I brought the .obj into Notch, I couldn’t figure out how to bring the .mtl with it. Is that possible or is the only workaround to have a predetermined material to bring in a C4D scene that’s already packaged?

I wish this community/ forum was more active. I came here looking for answers to this question as well. Any chance you figured this out on your own and would like to pass on the knowledge?
