No, PlayCanvas doesn’t support the import of .MTL files. .MTL files generally accompany .OBJ files, defining the material on the geometry. .OBJ files are actually really inefficient for storing 3D geometry. You’re better off sticking with FBX files, which embed material information (and texture data too if you export them with the ‘embed media’ option enabled in Max/Maya).
ok thx, I don’t exactly have maya or max but I am looking towards using blender because its free but I am going to use it when I buy myself a new PC. The 3d model software I have been using only has an export option of .obj files but I am not really familiar with FBX files.
