Cheers gster I'll try that spec advice and post back later.

You've pre-empted my next question... if I'm correct I connect the facing ratio of a sampler info node into the reflect and spec channels right? I've read in one place connect it to the y, in others, the z. What would you advise and is there any difference? Is there a way to get a scientifically correct ratio using the ramp values or do you just tweak? Black at the top of the ramp or the bottom? etc

You're probably wishing you hadn't bothered replying now, just looking for a quick guide to applying these. I tried before and wasn't convinced by my result.

thanks
