OK. A few points: 1) When I had something published, I was offered a flat fee or royalties ranging between 2 and 4% based on volume (higher percentage for higher volume), a few years ago. 2) Last I heard, Zygote offers artists 35% of what their items sell for. 3) I suspect we're now more likely to see stuff in Free Stuff that is "Works in Progress" and final items, with extra morphs and bugs worked out for sale at the Renderosity store. If I were any good at modelling, that's what I'd do - release a rough version (like the unposable version of The Ultimate Dragon that was here for a while) for free, and the final version with a few extra morphs and such for sale.
