I would be suprised if you were to get a definitive answer from DAZ describing the situation regarding all possible models you might create in the future, which contain some element of their products. I think such an answer would need to be either be so restrictive that it might unnecessarily stop people developing DAZ compatible products, or so relaxed that it might damage their position if they decided to take action in future on something they saw as infringing their EULA. You might be able to get a definitive answer if you were to ask about a specific example of a model you have made, or intend to make. I get the impression that DAZ reserve the right to refuse permission for elements of their products to be used in derivative works, but only excercise that right if the derivative work is considered to be in competition with their own products. So if you use joint parameters of a figure to make clothing that's probably OK, but if you use them to make another figure that's probably not (at their discretion). Having said that, if you were to use DAZ joint parameters to make a clothing item very very similar to an existing DAZ product they might well complain. This is just an opinion from a non lawyer, non merchant though. Ian
