Holomatix Rendition supports 3rd-party mental ray shaders, without the need for recompilation.

Shaders do not need to be recompiled to run under Rendition. Simply place the shader's .mi file and the .dll (Windows) or .so (Linux) file in the Rendition/Shaders/3rd-party directory.

Shaders tested under Rendition include:
