So I spent a couple of hours making a simple but interesting shape to put into my large track test and this is what i can up with.

It still needs a little work, i would like a nice shiny metal texture so i can get a nice environment map to reflect off it.

This is the first time i have used mental ray render settings and so far it looks good. But i will be calling on Andy to help me get a better effect as he is pretty good with mental ray settings.

I think i will just sit the shape in the scene, so i need to level out one of the sides of the cube so it sits level.
