Mecanim: modifying animation in script when animate physics in on, impossible ?

So usually when you want to modify mecanim animations using some script it’s pretty easy: animations are done by unity around the update function, so you can directly modify bone rotation in LateUpdate().

Now I’m using Animate Physics on my animator, which means that my animation are done around FixedUpdate instead, which allows my animation to interact correctly with physics (I need it because I have some cloths hanging on my character that are controlled by physics).

The problem is that modifying animations in LateUpdate doesn’t work anymore, because it’s not in synch with FixedUpdate.

Any idea of how I could do it ?

Thanks!

Should I report a bug for this ? It’s not really a bug, more of a feature incompatibility I guess.
