i still think a lighting challenge would be the funnest. Each person gets a random page number and has to compile a scene using any or all of the models on the page. shading and lighting. https://www.turbosquid.com/Search/?ke...e=0&page_num=1 That would actually be quite fun, and would be quite creative too, as there would be a huge amount of possibilities with the amount of items on each page. Screen grab of the page you were allocated as your first post would be a good rule, nobody would be able to claim their page looked different because of monitor size etc that way. I would consider coming out of temporary 3d retirement for that challenge, or another one depending what it is!
