Whatever expresses the artist's concept... Using ready made materials, models, textures, etc... is just the beginning. Being able to use these to express something original is where the art comes in. Those who are able to model and uv map have the additional advantage of being able to add to their works, but to just have the technical ability to use such programs will not in it's self make for a more involving image. To the viewer, the technique, the time involvement, the software used, etc should have very little if any impact... it's what their eyes see in the finished result, and the way it impacts them on an emotional level that is of the only importance. The difficult act of creating a unique vision to share, and not the materials used, is at least to my way of thinking, what it should be about. Saying that, I do believe, that learning as many skills, in as many programs as a person can, will make this easier to accomplish... Create, and express, using what you have... learn and improve techniques, think.... and enjoy the doing. best, hewsan
