Scooby-Doo is a Great Dane from 3D Model World (that site is no longer accessible) with my own texture and a collar from the Zygote Dog Pack. Daphne Blake is a Poser 4 Nude Woman with a skin texture by Tim Laubach, high-heeled shoes supplied with Poser 4, Tess hair by Zygote and a dress I received by email from John Stroo. Velma Dinkley is a P4NW reduced to 95% of her default height. She has the default P4NW skin texture, clothes supplied with Poser 4, Zygote Morph Hair and glasses from Royloo (no current link). The background is Awful Soul Wall and Chains, from the Renderosity email flyer of 2003 February 26.
All the characters appear in an image I posted to Renderosity in November 2001. The same Poser versions of Scooby-Doo and his friends appear on a card face set I made for the Mike’s Cards shareware solitaire package.
