>.< that doesnt mean anything, I make renders all the time that arent cut out, because they don't need to be if you are making sigs.
I believe they're called effect renders because they are not true abstracts. They're not meant to be the focal point of a piece of art, just to accent it. To create an effect within the art. Regular c4d renders could be used as the main piece and have effects added to them.
I think you are missing the point. A C4D render is a render made in C4D. It doesnt have to be a focal point of a piece. As long as it was rendered in C4D, it is called a C4D Render, not an effect render. They aren't rendered in a program called 'effect' are they?
