"This treefrog was entirely modeled in the open source application Wings3D. It is one simple mesh, save for two sphere shaped eyes. It took approx. 30 minutes to model. It is entirely procedurally textured. That's right, absolutely no bitmap textures applied. I used Eovia's Carrara Studio to create the procedural textures and render the image. I rendered out a .tif file with many extra alpha channels. To create the iridescent effect on the skin, I modified hue, saturation and lightness parameters in the x, y and z normal channels in Photoshop." -- David Benton
