It would be nice if you can specify some of your rules for the Competition.
You say it has to be 100% made by the competitors.
Does that count for every single texture i might be using? even if i have full rights to use it (like a wood texture or a HDRi sky I bought somewhere)?
How about creative commons meshes i got from blendswap or objects I bought from Turbosquid?
Does it count as infringement, when I show for example a Windows Desktop on a Display, where you can see the windows logo or any icons of other software like Adobe?
How about (TM) logos on items in general?
What If i model an iMac, do i have to alter the logo (although it is obviously an iMac).
Thanks for any answers.
