I 've included light setup in the scene file.This model was constructed with utmost care and attention to detail, with clean edge flow. Constructed from original photographs collected from internet .So the proportions will match with the real world object. Very useful in anatomy study and can be used in presentations for medical science.
Only Maya format contains the shaders and lit setup used for rendering(not in OBJ,FBX formats)
Make sure mental-ray plugin loaded from the plugin manager settings in Maya , then simply open the scene file and proceed for rendering for the quality shown in the presentation images.
