This is a character designed for an optical surgery hospital. The publish agency asked to emphasize the features that would make it clever, so we have glasses. I used raytrace map in the refraction channel of the material editor. To have an indirect ilumination, I used ambient oclusion (mental ray render) in an omni light. A second light was positioned be side the character to generate a direct shadow and a volume light effect. It has been concluded in minus of 48 hours of work.
