MERL Material
The MERL (Mitsubishi Electric Research Laboratories) BRDF database contains reflectance functions of 100 different materials. Each reflectance function is stored as a densely measured Bidirectional Reflectance Distribution Function (BRDF).
Free access to the MERL BRDF database for research or academic use is available at http://people.csail.mit.edu/wojciech/BRDFDatabase/
You can use these binary files with TableBRDF material type:
