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.
Wrong. It's possible to win art contests through procedurally generated art. Have seen people win way bigger amounts through bigger contests when compared to Roobet art contests out there.
Also, who in their right mind would design a generator just for the sake of a contest? Silly statement to be honest.
I don't know if there's a clarification about 3d art and if this one allowed it will just tolerate people to don't put any huge effort on the contest because as many people stated they can just generate it everywhere and then submit it to the contest thread. I do hope there's separate contest between personal created arts and 3d ones so that this will not go unfair to any artist who join the contest.
