3ds Max 2009 (+Design) - Importons & Irradiance Particles

If you already have (or will soon have) access to 3ds Max 2009 and/or 3ds Max Design 2009 then you're going to want to head over to the Maya forum to get the new ctrl.ghost shader. Many, many thanks to Max (not the program...but the man) for creating/sharing these shaders (including a 3ds Max version) that allows us to use the new Importons & irradiance particles.

Here's a direct link to the thread where you'll find the shaders (32 & 64 bit) & more information HERE

Now with the 3ds Max package you'll also get the mrGeomShaderObject.dlo file, place this in your plugins or stdplugs folder. Thanks to Dave ( for compiling the geometry shader. The Geometry Shader will be our access point to the importons & irradiance particles options.

The zip archive also contains the ctrl_ghost_settings shaders. You'll find both a .dll file & .mi file. Place the ctrl_ghost_settings.dll file in the shaders_autoload subfolder: ex. C:|3ds Max 2009|mental ray|shaders_autoload|shaders

Then place the ctrl_ghost_settings.mi file in your include folder: ex. C:|3ds Max 2009|mental ray|shaders_autoload|include

Now you're all set to start using these new options. To access the settings you'll first create a mr Shader object in your scene then assign the ctrl_ghost shader to it and drag that ctrl_ghost shader to the material editor as an instance copy then edit the settings from the material editor. Not clear enough, here's some screen captures:
You can find more information on these options in the thread listed at the beginning of this entry, and in the mental ray documentation included with 3ds Max. To access the mental ray documentation, go to: Help>Additional help...>mental ray 3.6 Reference
