In theory if there are no eye actors in the pose, one would not expect the eyes to be affected by the application of the pose. Unfortunately reality does not always conform to theory. :sad:

It's hard to know what to suggest. It's probably worth doing a render to see if the eyes still look wrong when rendered (might be an OpenGL problem). If the pz2 sets any materials, it's possible that this is a problem with materials, rather than joint rotations. I don't have a lot of faith that these suggestions will prove fruitful, but they are all I can think of at present, I'm clutching at straws.
