I think my brain is slowly taking it all in and I am starting to feel I can problem solve issues. That being said I have asked Clym for his expert help a few times as I needed guidance. The rig at the moment has stretchy limbs/arms and torso, locators and a reverse footlock. I have managed to get the reverse footlock working well with the stretch and it is causing no problems at the moment. Earlier I added bend to the wrists and I have been working on skinning the skeleton to the mesh.
I have also just begun learning maya muscle as this is the area of rigging I would like to know the most, mainly down to the fact that alot of the models I make are quite realistic and I would love to be able to get realistic jiggle/flex in the muscles. I will continue learning that and see how it goes.
