Kuan Yin is one of the most revered figures in Eastern religions. In Buddhism she is the Bodhisattva of compassion. in Taoism she is a powerful immortal, and in Feng Shui she symbolizes marital harmony.
The main statue, base, outer veil, and bindi (forehead ornament) are seperate pieces, each with fully manifold geometry.
The native Blender version uses procedural materials. The amount of patina on the brass is easily adjusted by changing a single property (see image above).
Export versions come with diffuse, normal, and specular maps which should work with most render engines.
