The OBJ data structure is quite different than the "flat matching array" used by Trimesh and GLTF so this may not be completely possible. split_objects Whenever the loader encounters an `o` directive in the OBJ file, split the loaded result into a new Trimesh object. split_groups Whenever the loader encounters a `g` directive in the OBJ file, split the loaded result into a new Trimesh object.
