kaveman, I'm not an artist, just a some-time modeller, so you can take my opinion FWIW but I feel the person creating the render has, by far, the hardest job & more than deserves the credit for the finished piece. All I do is fire up lightwave, push a few points & vertices around & out pops a model :-) You artist types have to compose, light, texture, set up camera angles, & do test renders from every point of the compass. And that's before you even get around to thinking about postwork. After all that you SHOULD be able to say "Yup I made this" :-) I doubt seriously that Da Vinci stepped back from the Mona Lisa & thought... "someone else made the paint, someone else made the canvas, someone else made the brushes, someone else made the easel, etc, etc.... who should get credit for painting the picture?"
