First failure on IKFK switch.

The rig in the video below is that I created follow a tutorial about building a IKFK switch. Ironically, everything apart from the switch seems fine, it is jumpy when it comes to the switch point.





I am going to solve it, and use it for one of the L4 film "Time Machine". Here are some tips I concluded by doing the two different rigs:

1.For spine, the spline Ik tool is easy to control for basic movement, but need to be careful about the Hierarchy. FK is used for taking full control of it.

2.Head applies to mainly FK, the only place for IK on head is when the head move left to right like it is in the india dance.

3.Arms need both IK and FK controls, for creating unlimited movement more easily.

4.Legs is mainly IK with knees on FK. For example, Kicking.
