This script exports Max scenes for use with the open source renderer Sunflow ( It supports all of the Sunflow shaders, geometry, lights, HDRI, particle systems, GI and photon settings, sampling, bucket setup and camera settings.

Additional Info: 

The main script (max2sunflow025.mse) goes in the main Scripts folder (usually C:\Program Files\Autodesk\3ds Max 9\Scripts)
The macroscript (max2sunflow.mcr) goes in the macroscripts folder: C:\Program Files\Autodesk\3ds Max 9\ui\macroscripts
The 4 icons (*.bmp) go in the icons folder: C:\Program Files\Autodesk\3ds Max 9\ui\Icons
Now start Max, go to Customize -> Customize User Interface... and add the macroscript
to a toolbar or menu of your choice (I always use the 'Extras' toolbar for my bits and pieces)

If you are going to be exporting a lot of particles, or very heavy scenes, it night be an idea to increase the memory allocation for MAXScript. You can do this by going into the 'Customize -> Preferences... -> MAXScript' settings, and increasing the 'Initial heap allocation' setting. I've got mine set to 64MB.
