This is a physically accurate light shader for mental ray in Maya and Softimage.  Here is a quick list of the main features:

  • Support for IES light profiles with real light profile intensities, and ability to scale profile intensity using real world units
  • Support for photometric (candela, lumen, lux) or radiometric (watt, watt/s, watt/m2) real world-units
  • A photon emitter that supports light profiles, area lights, and is linked to direct light intensity
  • Ability to use area lights with soft shadows while retaining IES profile sharpness/definition
  • Support for color temperatures
  • Light profile rotation
  • A shader to create object/geometry lights
  • A separate simple texture shader to add light profile support to other nodes
  • Works with both Softimage and Maya on Windows 64-bit and 32-bit, Linux 64-bit, and MacOSX (Maya only).
  • Free and open source (BSD license) with minimal restrictions, so you can compile for other platforms, incorporate the code into other free or commercial projects and redistribute.
  • Comprehensive manual
