Supported XSI Versions
Following XSI versions are supported:
- 6.x (Windows / Linux)
- 5.x (Windows)
- ModTool (Windows)
Installation
To install the plug-in you need to load it in the plug-in manager.
File -> Plug-in Manager -> Plug-ins -> Load, browse to the file and select it.
To install the Luxrender Shaders do the following:
File -> Plug-in Manager -> SPDLs -> Install, and select all the lux_*.spdl files
Run it
You find the plug-in in the File -> Export -> LuXSI.
If you click on it the LuXSI PPG will appear. Select a output filename (Main tab – filename).
and click “export all” to create the .lxs file which you can load in Luxrender.
Main options
In the “Main” tab of LuXSI you can set the basic settings of your lxs file. It allows you to change the screen size, gamma, filter,... and has special check boxes to export hidden objects/cameras/lights in the scene.
Render options
In the “Render settings” tab you can change the Luxrender render settings. Be sure to read the Luxrender documentation to get more details about this settings.
Materials
The concept of the plug-in is that you don't need to change anything in your XSI scene before you export it. LuXSI exports the XSI settings into Luxrender settings. At the moment following materials are supported:
[table missing, will be added later]
Texture support is still in a testing stage. It only exports textures which are directly attached to the diffuse slot at the moment!
Lights
Following lights are supported:
[table missing, will be added later]
When you use SunSky you can set portals in your scene (e.g. If your camera is in a room an the light is coming through a window you can set the window as a portal so Luxrender knows where the light comes in [less noise]). To do that you need to rename the objects in the scene which should become a portal. Just add “PORTAL” to the name.
Environment
If you want to use environment lighting in Luxrender you have to add an environment shader in the current XSI pass and load an “.exr” file (no HDRI support in Luxrender atm).
Camera
The normal XSI perspective camera will be exported to Luxrender. To add a Depth of Field (DOF) effect you need to add a “Depth_of_field” shader to the camera lens (Lens Shader tab in the camera PPG).

Current bugs
Windows path string not correct. May need to be changed from \ to \\ in the file!
Luxrender camera is not exactly the same as in XSI (fixed soon)
Textures only work in diffuse slot, not deeper in the tree
