recently I've downloaded a Rig ready for animation with all the cool stuff and scripts in it. What I wanted to know is how can I adjust this Rig to my character in size and proportions? For example if I have to fit that rig into someone like Gorilla with long arms and short legs. How do I adjust the skeleton's proportions without losing all the cool stuff, spline controls, and IK/FK switching possibilities etc. I tried simply moving the joints and scaling but it ruined the skeleton. Any help would be much appreciated. Thanks in advance.
P.S. The Rig has a global control for proportional scaling but that doesn't solve the problem of course.
