Lyrra, in case you guys do decide to elaborate on the Non-Commercial/Commercial tag definition, please consider a couple of points: ( from posts by Crescent & yourself) - "non-commercial use only" means no renders using those products may be sold - Commercial use : can be used in a render that the artist will get money for Please bare in mind that works may be donated, or used for non-profit, yet revenue generating endeavors, which would clearly still be commercial applications, i.e. someone donates an image, which includes a commercially restricted gun prop, and that image is subsequently used by the NRA in a national magazine ad. I would think that seeing his work in a full page, paid ad in Sports Illustrated is probably not what the original rights-holder had in mind when he stipulated no commercial use. Perhaps a broader definition of Commercial Use, avoiding the criteria of financial gain to the artist or the elusive concept of profit altogether, along the lines of: Any transfer, distribution or publication (other than the artists personal portfolio or exhibitions) that serves to either directly or consequently generate revenue. I think that such language would exclude all the "non-profit" loopholes, yet still allow folks to show their stuff on their webpage or in the galleries. ...but then IANAL either :-)
