The drUtilSuite is a collection of shaders for mental ray 3.4 through 3.9 that is aimed at making it easier to create custom networks of shaders. This may be useful when working on look development, shading or lighting tasks within mental ray, particularly when workin in Maya. The drUtilSuite includes around 150 shaders at present whose focus is to provide clearly defined atomic operations that may or may not be available already in Maya and mental ray. In many cases, the operations also mimic operations available in compositing packages such as Apple Shake but not necessarily available in mental ray or Maya.
The drUtilSuite is distributed free of charge. It would be great to see this library grow to encompass more of the functions not already present in the standard shader set. Please email info@duikerresearch.com with suggestions, questions, or pointers to typos.

The .zip file listed above includes versions of the drUtilSuite for Windows, Linux, and MacOSX ready to work with Maya 7.0, 8.0, and 8.5 (including OSX Universal Binary support)
The OSX and Linux versions now have the Boost library linked directly into the shaders, so compiling and installing the libraries won’t be necessary.
2011.03.04
– Added Maya 2010 and 2011 support for all platforms
2007.07.07

The development of the drUtilSuite was inspired by the work of a few very talented engineers at the former ESC Entertainment, and the engineers behind XSI’s mental ray integration before that. I would like to thank Uwe Behrens, Jason Bright, Masuo Suzuki, Tadao Mihashi, and Andy Lomas for the inspiring work that they put into the former escBase shader suite. No longer having those shaders spurred the development of the drUtilSuite.
