aaahaaa!!! Now I did this when I learnt Lightwave a few years ago. I can point you in the direction of a certain Dan Ablan, hes an absolute guru of Lightwave and has some good books out there. Now the book I'm thinking of has a yellow racing car on the cover. Thats the book you want!!! Sorry cant remember the name though, but look up this guy anyway. Its all done with fractals and crumple procedural shaders in Lightwave itself, very good!!! or you could check out www.flay.com,
big Lightwave site!!! Lots of tutorials even for Maya guys too!!!
