Hello, I have a few .obj files that I was hoping to convert to stl and use in Mujoco. Some of those files are concave, and would need to be broken up into separate files each being convex. Do you have any recommendations for a tool that would do this automatically (i.e. given one 3D model, generate a series of STL files and their placement so I can load them in Mujoco easily?) Thank you and have a great day.
