grass wind shader

[Alienhead]

I was setting up the vegitation system yesterday and ran into a snag, No matter what settings I adjust the texture,material or shader lineup too - I get a horrible light shift when rotating the camera.  I've included a video of whats happening.

I have a feeling it could be the normals on my grass mesh, but I've edited them to nearly all angles, still got the light banding.

Was hoping I may just be overlooking something but if I am, it's eluded me the past 48 hours.
