Cheers Some Guy but that's not it. The result is the same on production quality and with stadium lighting. I've tried a multitude of the settings for filtering, anti-aliasing etc throughout the day. It could be some setting that I've missed.
It looks like some kind of multiply problem, gain, offset problem. Gah. I wish I was born technical :p

The problem may look minor in this context but it looks terrible on the hair and eyelashes (then again that could also be my sloppy and badly painted textures ontop of the matte problem )
