Reply To: How to realize the motion that a rigid body moves in an elliptical path?

Split the two motions. So, the green object spins using MRF or sliding mesh. Moving mesh can then be used to bodily move the green object. Note, that's moving mesh with no remeshing. Or, you can mess with the gravity vector and just spin the green object. Either way I suspect it's UDF based but defining the path mathematically may not be easy.
