We call it a Renderosity Contest because it is hosted here and only involves our members who have purchased the products. Also the money prizes are coming from both BBAY and Renderosity. Either way you stack it up, it's a contest where if you spend or have spent any money over there on products (most things cost $30) you have a chance to win $500.00 not a bad investment if you ask me. In regards to BBAY artists, yes they can join in the contest, but it has to be from using a product that isn't theirs (something created by another artist - its only fair). Jack
