Hi

I have imported .bvh tracking files into blender to animate. The problem is the blend shapes are selected too, and whenever I parent the face mesh to the motion data, it distorts it.

Is there anyway to remove the blend shapes without it affecting the motion markers?

Heres a screen shot the of the problem
