Embodiments of the invention provide a method for extending a graphics rendering framework. A rendering application locates a first file that includes a first implementation involving a first graphics material and compares data associated with the first file to data associated with a second file that includes a second implementation involving a second graphics material. The rendering application compares data associated with the first and second files, determines that the first graphics material matches the second graphics material, and determines that the first implementation is different from the second implementation. The data associated with the first file and the data associated with the second file are then combined into a data structure. Advantageously, new graphics materials, and implementations for existing graphics materials, may be created without access to the source code of the original implementation of the graphics materials and may be installed at a later time without re-shipping the entire library of graphics materials and implementations.
