Animator and custom blended animation

Hi everyone,

I have been trying to make addition blend animation on top of Mecanim's Animator.In my configuration, I must use Animate Physics on Animator (when I don't use this, system works correctly but fails in other respects). If I am correct, the animation is then done in physics thread. When blended animation either fully ovewrites Mecanim's animation for certain nodes or it's weight is zero, everything works perfectly. The problem appears when I want to blend those two animations (when both are actually present). The animation is jumpy in that case. It won't work in Update nor LateUpdate.

My question is, is there any way to perform update after physics thread has already updates node's position? (maybe some OnRender on camera, haven't tried that yet) Is there any other way to do those blendings correctly?
