blau, yes "select the home key" does mean press it. just my Scottish way of saying things! the catsuit is what I was doing when this whole thing started. if you're interested, I was trying out 'negative reflection maps' (which I call blackchrome maps). basically, all I did was invert a few reflection maps to see what would happen. it's interesting, but not quite there yet. if I get it sussed, I'll post it. maclean
