I've been using this for a long time. Recently I found it was a lot easier to animate a tentacle if the "head" was locked to the CUA atom. The effectors affecting the "tail" only. Precise positioning of the head is no longer reliant on the position of every effector working together.
By default all effectors are parented to the CUA atom, I undo this so they stay put when I move the CUA. It works great. But every time I load a saved scene, they've reverted to being parented to the CUA, breaking the animations. Any way around Is this kind of the same effect you get by editing the “weight” slider?
