Oshyan, I've never seen anything like this in Vue, so I asked the author about it. He said he did the whole thing in Vue 6 and minor touchup in Photoshop. His work is stupendous. The only thing - it's fairly small...maybe he sells the larger versions or else the render times are prohibitive. I wonder.
I've seen this a lot with Vue - some of the artists are absolutely fantastic, while the majority of other peoples' work is okay. I assume this is the way it is with all 3D software packages, but this contrast seems to stand out more to me among the Vue product line and users.
