Mandatory credit/mention is NOT included in the Renderosity license. End of story.

Freebies are another matter all together. If the creator deems that in order to use their work in a render then credit must be given then that's the "price" of the freebie so to speak. The day that mentioning everything I paid for in every render I do is mandatory is the day I no longer make a render. I don't mind doing it if it's for a freebie - I don't even mind doing it for commercial products that I buy. But being told I MUST on a product that I also gave someone money for is where I draw the line.

How many ads do you see with a disclaimer at the bottom: Fonts by "..."; Stock Photos by "....", Lineart by "....", Design by "..."??? The answer is none. That's because print and production houses pay for those items. There's now an assumption that the item is royalty-free because the organizations in question bought them for that purpose. Does every newscast mention the brand of film used or the camera used? Nope. Same reason.

I also try to credit the vendor whenever possible when I do a render out of courtesy and because I always like to see a vendor sell more from the exposure if I can. I loathe the idea that it be compulsory. Not when I've paid for it. There I draw the line...  And it's there I stop buying. Otherwise, if I must mention the creator, I want a royalty fee. Just to be fair...
