Export from 3dstudio max

i have a problem with exporting 3d models from 3dstudio max. I did not understand why some models once loaded on sketchfab do not have the possibility to assign a material to a shape, the whole model is seen as a single shape.

Tank for help me.

Hi, What objects are you trying to apply materials onto on sketchfab, I assume you have separate material ID’s set for them for separate materials in 3ds max?

Thanks for your answer. I understood the problem and solved it. Actually the problem was material id. :slight_smile:
