As far as the rigging is concerned anyway. I have managed to fully rig the wildebeest with very little trouble.
This is largely because I raised the problems I was having with the elephant and rhino rigs with the tutor, namely how the whole geometry of these rigs was influenced by the leg joints. He showed me a tool called the Paint Skin Weights tool which is used to control the influence each joint has on certain areas of the geometry. This is done by painting areas that are supposed to have little influence from certain joints black; and areas that have a lot of influence from joints white.
