I guess my question ether was confusing, no one knows the answer or I was not very clear. I hope this picture clarifies things. When setting bone constrains, Carrara 3 has two deferent places ware this can be done? Why? They seem to produce the same results. The one on the left is through the Skinning menu, the one on the right is through the Motion tab. I am trying to animate a model of a bird walking, I was wondering which should I use? Or dose it even matter.
