Here's the component I use to do the collision mesh update. You just attach it to the object that has a SkinnedMeshRenderer and MeshCollider, and whenever you need to update the collision mesh (triggered by playing another animation, etc.) just set the "forceUpdate" flag on this component. It only works with Unity 2.1 (or later?) [ american-writers.org ]
