Don't really understand the logic of how giving a freebie creator credit in a commercial render would help them...to me it would seem like a deadend exposure. A buyer of a commercial render would most likely not care as it is the end product, the render, they are interested in. I doubt seriouslly if they would be in the market to purchase a '3ds sled prop' or a 'Poser5 dress model'. Don't misunderstand me, I am not trying to stir something up here... I am just curious.
