Updating a mecanim for different models?

Hello,

I was wondering what the best way to do this is. For example, if I were to download one of the free motion cap mecanim packs from the asset store, it of course doesn't match exactly with a model i want to use it with. How would I go about updating this animation to the model I want.

Is there a way for me to apply the downloaded mecanim fbx to my own model like in Blender or something, and then update it in blender and re-export it?

 

Better to ask this question in the Animation subforum. This subforum is mostly useless gossip.
