If ac is an actor, then ac.Gimbal() is "Get the gimbal information for the actor. This method returns a tuple of tuples. The first sub-tuple contains the gimbal order (e.g. (1, 2, 0) for Y, Z, X). The second contains the parameters that correspond to the x, y, and z rotations respectively". OK, and I have got it to work.

But there is no actor.SetGimbal() method to apply a change to the rotation evaluation order, as can be done manually by the user in the Joint Editor. method to change the rotation evaluation order; the user has to do this manually in the Joint Editor. Please provide an actor.SetGimbal() method.
