Advanced Shading Language Interface. In Maya, the ASHLI plugin allows users to see FX files containing HLSL (High Level Shading Language) and GLSL (OpenGL® Shading Language) shaders.
The ASHLI plug-in makes a new shading material available in Hypershade which contains an attribute that you can connect to an FX file.
As of Maya 2009, the ASHLI plug-in is now available as part of the Maya Bonus Tools. Bonus Tools is a free collection of useful Maya scripts and plug-ins that are available from the Autodesk Web site (www.autodesk.com/maya-bonustools).
