Headwax: No procedural shaders as yet just a colour texture map, bump @ +24%, a light grey highlight & Shininess @ 35%. Render time wasn't too bad but once animated with the rest of the scene it may be quite lengthy.
So, PSs may be an option worth looking at a bit further down the line.
Arik: I will be doing bits here and there on this project as and when I can squeeze it in. Having a little difficulty with getting a convincing track layout. Bending it on one axis is easy enough but when you start doing compound bends (2 axis) it starts getting confusing.
Headwax came up with a great idea of using bones for the track bending instead of deformers.
Hmmmmmm quite a good idea that!
