If you busy cre­at­ing 3D dig­i­tal models and don’t know about the Netherlands-​based CG Tex­tures data­base, it is worth the look. Run by a friend, Marcel Vijfwinkel, he gen­er­ously has an open source atti­tude to the con­tent. You can read the license here. A lot of the mate­r­ial comes from Marcel him­self from his work in the gaming indus­try, and the site now has many con­tent con­trib­u­tors. If you or your office are able to pay for a year-​long mem­ber­ship, it will sup­port the site and give you mul­ti­ple perks.
