      Try it with Kinematics. Fredo has a video on his channel that covers it.

        Just tried using Kinetics and I can't get it to work either as kinetics are always on but as I have 6 different movements that all need different constraints it isnt working. I have also tried turning them on and off when I need but that doesn't seem to work either

          Have you looked at Animator? It will allow you to animate groups and subgroups at the individually.

            Yes that's what I was doing before looking at Kinematics. I have sort of learned that its good until there's too many movements with rotation's which is what I'm finding here and didn't know if anyone had come across the same issue and solved it

              I'm presumed it was a question about Animator as it is asked in Animator forum.

              The strategy of grouping everything to inherit the parent group move can result in unwanted results. Kinematic Constraints added to the MASTER then the SLAVES can move as desired.

                Interesting. Is there a link to a kinmetric plugin? I did not see on in this forum.

                  Animator has a Kinematic Constraint feature...

                  ...with various methods to apply it

                  There is no separate plugin needed

                    Thanks, Rich. I cannot do anything any more and did not remember that. I need to go educate myself about kinematic (like what the heck it really is/what does it do).

                      Basically its a chain. If A moves tell B and C to follow it but keep their position in relation A the same (unless instructed differently).

                      Same principle when you drink beer.
