Last week's tutorial dealing with rigging, though of more mechanical bodies.
It is a hydraulic metal leg, such things use in Terminator or any other mechanical character.
It was a really straight forward tutorial, and even more im understanding how IKs and Joints work, also how to connect the control to the actual joint structure.
Here is the picture with the outliner organized.
but also because we are getting into animation, I decided to just show the movements of the leg , just upwards and the toes.
