This is my most up to date rig. It's much more flexible than my last 3 that I posted on here and the mesh is much more clean and appealing. There's also a new facial rig system, which uses controllers in view the viewport rather than sliders in the side bar, although they aren't directly on the face. I'll be posting more characters (hopefully a bit more appealing) and improving the rig later on, but for now it's just this one :)
Like last time the layers are in the sidebar, all labeled, as well as the ik/fk controllers and the stretch controllers. The deformations on the arms and legs are waay better than before, you can now rotate the upper bones on each limb and not horribly deform it. Although, doing the splits is not recommended yet :/
This rig requires blender 2.57 and up, or else you won't be able to access all the options in the sidebar.
If you link the character into another scene and make a proxy for the bones, make sure they're named Guy_Rig and not Guy_proxy or else the properties won't show up.
