Technical Journal (Rigging- part 02)

In this journal, I would like to talk about how I had done twisted rigging joints for the body, arms, wings and the neck. Before I continue, check the video below

Ok, now you can see how orientation of the joints works when I rotate the chest. For getting such kind of twist I just simply used connection editor by making a connection between rotations the controller and Ik spline handle as below(figure-01)

But, here is some different when I was working on arms and the neck, the wings as well. In this case I don't want to make some unnecessary joints are twisting around. Please, watch on this video below to make it clear.

As you see in this video, the elbow joint don't twisting around when I rotate the wrist of the arm. Instead an additional joint between wrist and elbow is twisting and it look more nature. This is what I want and that's why I put some additional joints for naturally twisting purpose. I used expression editor for those kind of twists by putting simple commend expressions and creating new expression.(figure-02)
