obj file loaded as Scene object instead of Trimesh object
I have the same problem. You can access the "geometry" member of the scene, but I have no idea how the original mesh is split into multiple ones. Following.
I'm trying to load a mesh from an .obj file (from ShapeNet dataset) using Trimesh, and then use the repair.fix_winding(mesh) function.
But when I load the mesh, via 
trimesh.load('/path/to/file.obj') or trimesh.load_mesh('/path/to/file.obj'), 
the object class returned is Scene, which is incompatible with repair.fix_winding(mesh), only Trimesh object are accepted.
How can I force it to load and return a Trimesh object or parse the Scene object to Trimesh object? Or any other way to fix winding of the triangles?
Using:
Python 3.6.5
Trimesh 3.0.14
MacOS 10.14.5
