There's a is difference between non-distribution clauses and non-commercial clauses. Here's how I've always understood it: Non-commercial clause: you can not use this item in any way that will directly result in you being paid for it. (If someone likes the image and commissions you to create a new image which does not use the item in any way, that does not violate the agreement.) Non-distribution clause: means you can not offer up the item to another person, whether or not you make money on it. No commercial distribution clause: toss the item around how ever you want, offer it on your site, email it to the world, etc., so long as you do not make any money from the distribution of the item. All of my stuff has non-distribution clauses but there's no restriction on how the models are used in the rendered output. If you make a million bucks from an image with my models in it, feel free to cut me in for a percentage, but it's not required. But, please feel free to do so ... I'll be your best friend. ;-}~
