I have included light setup in the scene file.
This has been modeled with good production standards.
This model was constructed with utmost care and attention to detail, with clean edge flow for rigging / facial comfort.
Model file contains inner mouth,teeth n tongue geometry also.
Textures / source images haven't been used.
Used only Maya / Mental-ray shaders applied to selected faces with the colors as shown in images in the presentation page.
Constructed from the self designed concept drawing.
Only Maya format contains the shaders and lit setup used for rendering.other formats provide only model geometry.
Make sure mental-ray plugin loaded from plugin-manager settings in Maya ,then simply open the scene file and proceed for rendering for the quality promised in the presentation page.
Hope U like it.
