I am creating a bicycle like chain and gear arrangement. When I came to run the simulation I added gravity and 3D contact but my 3D contact was ignored a weird way. I set my entire design to be in contact with every piece but when I run the simulation the chain goes through my gears and only makes contact with the frame. When I turn the chain sprocket sideways it makes contact with the gear so I turned the geomerty and 3d contact to maximum but the part still penetrated. Is there anythinf else that could cause the gear to be ignored from 3d contact even though it is listed in the 3d contact feature?
