I think that if you submit a Generated 3D Art, I think it won't have a chance winning on the roobet tournament especially if the 3d Art generator is open in public. You will have a chance if the generator you have is made by yourself and entirely made for winning the roobet tournament. I believe that judges is considering the hardwork and efforts of those artist so submitting a common generated art even if it's 3d won't stand a chance against hand drawn arts.
