I don't understand what you are saying. Okay so what I said was that he is blatantly copying a concept art. Now that in itself is not bad however not crediting the artwork in my opinion is very wrong. That's simply what I was doing. Click the word "artwork" in my comment to go to a link of the original artwork which was copied by the project creator and not credited.
I do not know what you mean about "render" I think you are mixed up :P
