Looks like I opened a can of worms by disagreeing :laugh:
What makes it funny is that if I post an image at rendo and I've used someone's content I do give them credit, I just don't like being obligated to do it for something I've paid for. If I create an image, I don't render it, my processor does and I don't have to give credit to my AMD 64 X2 4400 every time I post something. I see no difference there than if I used a figure from DAZ, or Renderosity for that matter, as long as I've paid a fair price for it then it should be mine to use as I please.

This all goes back to when all 3D artists were purists and had to be modelers as there just wasn't any content to use. Times have changed and so has the market, content is now becoming big business. To my mind, its the content retailers that should bear the advertising burden and not the end user. I don't think there is any other market where the end user is obligated to advertise the products they have bought, so why should 3D be any different?
