This xsiaddon file is a wrapper containing several unexposed Mental Ray shaders for XSI. The interface has been improved according to the Mental Image documentation.

 These shaders are included : Car Paint - Ambient and FG Occlusion -  Glossy Reflection and glossy refraction - Physical Lights - D2S_Lights, which combines "physical_light", "mib_blackbody" and "mib_cie_d" in order to reproduce realistic illumination, and last MR versions of "DGS_Material", "Dielectric_Material", and Volumetric Shader "Participating Media"

Mental ray 3.4 provides several new shaders that are not yet exposed in xsi 5.1 user interface.

This xsiaddon just installs a wrapper which gives you an easy access to these shaders.
 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 : [link] )
• Ambient and FG Occlusion   (see doc at [link] or [link] )
• Glossy Reflection and glossy refraction
• Physical Lights
• New version of D2S_Lights, which combines "physical_light" ,  "mib_cie_d" and "mib_blackbody" in order to reproduce realistic illumination.
• Last MR version of Physics Shaders ("DGS", "Dielectric" and "Participating Media")

============= D2S_Lights V.2.0

 This version of D2S_Lights includes the possibility to switch between "mib_cie_d" and "mib_blackbody" to get the Light Temperature Color.

This is useful when temperatures below 4000 K are needed, since "mib_cie_d" (which is more accurate than blackbodies between 4000K- 25000K), does not work below 4000 K as it is specified in the MR Documentation.

The CIE Color Chart is now included in the interface.

Warning :

• If Area Lights don't seem to work, just turn your light source by 180°  (XSI bug)
• When opening an old scene with previous version of d2s_light, it will be necessary to set the light shader again

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.
