Mental ray 3.4 provides several new shaders that are not yet exposed in xsi 5.01 user interface.
This xsiaddon just installs a wrapper to give you an easy access to these shaders.

This addon is composed of spdl files to expose the shaders in xsi. The interface has been improved according to the Mental Image documentation.


Here is the list of the shaders that are exposed through this addon
- Car Paint 
  (see doc at LAmrUG : http://www.lamrug.org/resources/doc/paint.html )
- Ambient and FG Occlusion 
  (see doc at http://www.lamrug.org/resources/doc/occlusion_tutorial.pdf 
   or http://www.cg-academy.net/pages/free_tutorials/tut_ambient_occlusion_shader/tut_mentalray_ambientocclusion_shader.htm  )
- Sub-Surface Scattering 
  (see doc at http://www.lamrug.org/resources/doc/sss-skin-tutorial.pdf 
   and tips at http://www.lamrug.org/resources/physsstips.html )
- Glossy Reflection and glossy refraction
- Physical Lights
- D2S_Lights, which combines "physical_light" and "mib_cie_d" in order to reproduce realistic illumination.




Release notes:

This release doesn't provide SSS spdl anymore until we fix a naming issue.
Fixed an issue with Edge Factor parameter that was not correctly linked.
Included pdf from xsi TD Love Tour.

****** IMPORTANT NOTE ********
In case you have an issue uninstalling the previous version of the addon (xsi might not render after this stage).
Just open a shell, go to "c:\softimage\xsi_5.0\application\bin" and then run "runonce.bat", this solves the issue about SSS spdl pointing to the wrong dll.
