Several high-quality hair textures and transparceny maps made by a (Japanese?) artist named "Kozaburo" are available on the web at http://www.digitalbabes2.com, along with several tutorials as to how to use the hair. There are no README files available on the site, and nothing on the site indicates that the files are not available for commercial use. The way the tutorials are structured seem to suggest that the author intended unrestricted downloads of the hair. Therefore, is it all right to use kozaburo's hair in commercial renders as long as the proper credit is given? Several merchants on this website seem to have done so already. I thought of trying to contact Kozaburo via email, but wasn't sure if s/he'd understand my English. Does anyone have any additional insight into this issue?
