Hi all, I seem to be having trouble importing .stl files from things I make in OpenSCAD. Attached are two test files for a simple rectangular prism: oscad_test.stl is directly exported from OpenSCAD, while oscad_meshlab_test.stl is the same file re-exported via MeshLab. When I include <mesh file="objects/oscad_test.stl"/> in my .xml, MuJoCo crashes. Replacing it with <mesh file="objects/oscad_meshlab_test.stl"/> appears promising, however attempting to spawn an instance with <geom name="bolt" pos="2 2 1" type="mesh" mesh="oscad_meshlab_test" rgba="0 0 0 1" material="BasketMat"/> then results in the warning WARNING: Nan, Inf or huge value in QACC at DOF 6. The simulation is unstable. Time = 0.0400. followed by the program hanging indefinitely. I have MuJoCo Pro 2.00 on Ubuntu 16.04, however I am working with the C API. It is especially frustrating since .stl files from other sources e.g. https://github.com/cxy1997/Robotiq-UR5 work fine, with no issues in controlling the robot nor rendering the scene. Any help would be appreciated. Thanks! Edit: Added a small .xml scene with the prism, seems to work fine in ./simulate .
