I think spiffyandstuff does bring up a legitimate question. I always read the "readme.txt" files to find out what the model's creator has to say, and all of these messages vary widely. Some just "have fun", while others say you can make images, but don't re-sell the model, and frankly a thousand other variations that are in fact GREY. What WOULD be really helpful is someplace on this forum where a basic set of 3 or 4 categories could be drafted up and agreed to by model creators as to "what they intended to mean". A category 1. model might be completely restricted to no commerical use (NCU -like a movie rating) while a category 4. model might be Do Whatever You Like, etc. The creator could put this category in the readme and refer people to Renderosity or wherever for the complete details on what it means. Also, saving that the creator of the model "wants some of the money" is also a vague concept, and some type of basic understanding could also be drafted up to state basically what this means, and how the creator would be paid, etc. You can attack me all you want for suggesting this, but nobody else in the "real world" can operate without some type of guidelines. Especially when each "readme" file, isn't really clear about what the creator expects. Posting such guidelines at a well known public forum, like this one, might be really helpful to all concerned. It doesn't have to be a legal document, just a set of categories that can be referenced by everyone.
