Hi Jack, I don't see any problem with the snippet. Do note that in both cases you are showing here, the linear position and angular rotation of your mesh 0 are explicitly set as being the same as *cube_body*. Therefore, the velocity and angular velocity you defined, especially your custom *mesh_lin_vel*, will not have any significant effect in determining how the mesh moves. Unless your *cube_body *is also controlled by you to be moving at *mesh_lin_vel *of course.
