OpenPBR Surface is a specification of a surface shading model intended as a standard for computer graphics. It aims to provide a material representation capable of accurately modeling the vast majority of CG materials used in practical visual effects and feature animation productions.

OpenPBR Surface is an open standard hosted by the Academy Software Foundation (ASWF), and is organized as a subproject of MaterialX.
