Shading is always fun, at the same time, it is really hard job.
During this work, I mostly focused on surface materials rather than painted textures.
I used Maya Mental ray as a renderer for this project. I really miss using renderMan.
RenderMan is still too expensive to use for personal purpose.
What is the best renderer? I will say,
RenderMan > Vray > Mental Ray.
That's right. I am using third best one now. Sad....
