Like Moe, I suppose my biggest challenge was for a competition over at the Lightwave forum. I made a kind of underwater dragon thing, some dolphins, and the scenery. I knew next to nothing about Lightwave when I started though I knew roughly what I was doing with sub division modelling in general terms. I had to learn procedural texturing, lighting, volumetrics and displacement mapping. Made masses of mistakes and learned a hell of a lot. I loved every minute of it :o) - Baz
