Absolutely no need to shut up!!!!!....you are right to question!!!! This has always been a sticky area and it all depends on how the render is used. There is a limit to what another person can do with a render. You are not giving away the model and all that goes with it OR the expensive software needed to generate that render. The problem arises if you provide lots of different views that essentially reproduce the product. From what I can gather, DAZ want customers to use their products innovatively...i.e. make use of our expensive software (Poser 7, Bryce, Photoshop etc) and products and provide materials that even the 2D community seek. There are many uses for Poser output.....from scenes to animation to imagery. Personally, I do all of them! At the end of the day, appropriate rendering in Poser requires a knowledge of good lighting, the material and cloth room AND the animation palette.
You keep posting....I found your observations very interesting as I too have had a problem with some earlier work on this site where poser renders where offered just as a collection pngs with a single animal/object provided in all different poses and angles. This, I do not agree with.
Sorry for the long post....BUT....I am partly in agreement with you......but NOT particularly on the legal issue as you state it. it all depends upon how the renders are presented.
Will investigate further for you.
