This dispute about found materials and freestuff comes up in the Poser forum again and again, and it is pointed out each time that a painter doesn't have to make his/her own brushes and paints to be a good painter. If you tell me that Max Ernst's collages are somehow inferior as works of art because they rely on found material, then I beg to differ very strongly. Similarly, in computer art, one takes one's raw material where one finds it. The art is in the vision, the ideas, the composition. Hence a picture that relies on a simple primitive is not necessarily inferior to one that relies on a home-made model that took 20 hours to make in 3D Max.
