Maya - DVD Shader

Another tutorial from digital tutors.

I modelled them using a polygon pipe, in hindsight I should have used nurbs as there ended up being way too much geometry.

Here's the shading network. I used an anisotropic shader, plugged a ramp into the spec and duplicated it with slightly different settings. The blinn has the transarentcy turned right up and the difuse right down so only the reflectivity is seen. They are all then put on a layered shader.

Here's the finished result. It has some strange artifacts in the center of the DVD and I couldn't work out why. I'm not too worried though as I think it looks like flaws in the plastic of the DVD
