Why did mv.save did not save any *.png files in img folder? Thank you.

Did the model successfully output meshes before? Does only the rendering fail, or also the mesh output?

@yefeng1992 I have the same problem. Have you solved it?

We updated the repository to Python 3. This allowed us to change the used openGL-based rendering to pyrender. This should resolve the openGL problems.
