I think some distinctions should be made here. I never claimed not crediting is "illegal". I was merely refering to the ethical side of it. 3D as a form of art is relatively new, and as such poses new ethical questions. I absolutely do not agree with the "brushes and paint" alegory. A Vue artist's brushes and paint are the program itself and its tools. A car one adds to its render is not tool, it is a complete model, a finished work done by somebody else. Now i know that many times it is hard to find out who did it, and that sometimes it is simply impossible to give the right credit. But i do insist that whenever possible, a credit should be given. Now what Gebe mentioned is a far more serious issue. Those scenes on the Vue CD are there as examples for exploration and study. I personally discovered at least 3 images at the gallery which where not much more than my own scenes from that CD, a little modified, different camera angle, some objects added or deleted, etc.. This is pure violation of copyright law. No one would like to see his/her works of art displayed under somebody else's name. I believe this was done with no bad intentions, but it simply should not be done, and such images should be removed by the administrators.
