But well... Shader itself is really straightforward. But not many people want to do still life with Superfly But a lot of people do it with Cycles. Mystery.
Still life takes a certain mindset, I think. It's something I'd like to do, but I haven't ever managed to. I think where I struggle is the background. I can get my subject, get it framed, textured, etc... and then spend days struggling to compose a background. With still life, it's even harder for some reason.
Either way, that shader is beautifully done, and so is the render.
