Been poking at LIBERO and RoboCasa 3D sim assets and noticed almost every object's collision geometry is just a box, and they share the same density and friction values across the whole benchmark. Which surprised me, since a lot of manipulation -> OpenVLA and GR00T LeRobot seems like it'd depend on…
