I'd also recommend playing with the anisotropic node (under lighting->specularity). To get an idea of what it does, load the node, and plug it into either the colour or value of the root specularity "socket". It has the effect of "sort-of" concentrating the highlights, making them more intense. Then play, play play:-)) Anisotropic usually (in the few experiments I've tried) seems to darken the underlying material somewhat, so you may need to increase the diffuse to compensate.. I've just (over the last couple of days) started playing with this node and am having great fun:-)) Cheers, Diolma
