I teach 3D modeling to High School students. Correct Attribution and Plagerism are 2 of the most difficult concepts to get accross to kids. The problem is made greater by the fact the Artists are constantly borrowing each others work. When I use Poser I am using the work of both the people at DAZ and Curious Labs (and who knows how many others) I teach my students that when one is doing work for educational purposes, it is usually sufficient to provide attribution only and not obtain permission. As soon as they attempt to publish the work (say to the web) they must also obtain permission from the original Authors. In all cases they must provide me with a list of objects models etc that they have borrowed from others. (Including each other) I am right now having a very serious discussion with a student who has created a beautiful short Star Wars based animation in 3D Studio that uses Lego men he created from scratch. He has made all the meshes created some of the textures and done hin own animation. He wants to use a sound Track from the Matrix so that he can submit it for his portfolio. Fair use says that he can use 30 sec or 10% (which ever is less) of a music work without obtaining permission. His animation will be 60 seconds long. He thinks that I am being overly Anal to worry about this. I am telling him that if anyone is concerned about correct attribution it is going to be an Art school and it is critical that he do everything by the book. I wonder if anyone has ever been denied admission to a school because of incorrect or inadequate attribution???????
