I made this picture with a “leftover” model from a shortmovie I worked on (you can find some informations under the following link: http://www.behance.net/gallery/19381185/Photorealistic-Bird).
The bird was modeled, shaded and rendered in Blender by me.
A fellow 3D artist rigged the bird in Blender and created the textures in Mudbox.
The picture took 6 minutes to render on CPU.
We only used feather textures for the mainfeathers on the wings. I covered the rest of the body with a few hair-systems for the sake of convenience.
