I'm trying to move these meshes along the spline like tank tracks. If I can just get them moving along the spline to begin with I can probably figure out the rest. I can't seem to find any tutorials that guide me with this. The videos from Peter Pankras aren't helping. I'm not looking to animate wheels or sprockets. I'm also not wanting to do the UV style animation either. Can anyone help me?
