When I want to CollectClip to make an iMotionPlus I want to save the head and eyes rotation values which is based on Look at.
But it doesn't save those values for the head and eyes that is caused by it.
So is there a way to preserve the rotations values without the constraint?
In other words, how do I bake the bones angles for the head and eye rotations?

If you click on the "Bake Constraint Key" right under the "Motion" in the iMotion+ panel, it will bake in the look at, and any other constraints.

Thanks Rampa!
I knew I seen the option somewhere but could not remember where.
Ironically, it is located where I didn't want to use it until I found it.   
I said, I need to find it again before I export another clip.
