Download and Install
You can download the addon from this link .. http://www.luxrender.net/forum/download/file.php?id=16908
Plugin, LuxRender binaries, spdl files for shaders and shader presets, are included into addon. You do not need any additional installation.
See this video for more details to install from .7z file. [Link:http://dl.dropbox.com/u/16848591/luxsi_wiki/install_luxsi_zip.avi]
Run it
You find the LuXSI Renderer in the Render mode, Option Render -> LuXSI.
If you click on it the LuXSI PPG will appear.
Manual
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, display interval, and has special check boxes to export hidden objects/cameras/lights in the scene.
|
|
Materials
|
The concept of the plug-in is that you don't need to change anything in your Softimage scene before you export it. LuXSI exports the Softimage settings into Luxrender settings. At the moment following materials are supported:
|
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: (You must set some specific options for each type of light.)
|
- 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 Softimage pass and load an “.exr” file or HDRI.
Camera
The normal Softimage 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).
FAQ
I exported a simple scene and get an error while open it in LuxRender
- LuXSI doesn't perform a check yet if there is no light source or camera exported.
- Check you scene in XSI and see if the camera is hidden or the light source.
- You can switch on the "Export hidden objects/lights" box in LuXSI or unhide the things.
How to get smooth objects
- Select the object in XSI and change the subdivision level by clicking + on the num-pad or in the GeoApproximation menu

Current bugs
Textures only work in diffuse slot, not deeper in the tree
Change log
- Version 1.1.0:
- Improved support for PLY files.
- Added 'override geometry' option, very useful in large scenes.
- With 'override geometry' can change lights or materials without having to re-export the entire scene.
- Now we can use the PLY format for exporting geometry for use in animations.
- Added support for animation.
- Now, when you export the animation, LuXSI creates a .lqx files.
- LuXSI can launch LuxRender with option -L for load .lxq files.
- Added option 'framestep' you can export part of frames or entire animation (frame step 1).
- Added compilation a plugin for systems with SSE2 extensions (32-bit).
- Added x64 versions of the plugin for Softimage 2010, 2011 and 2013 (not tested with versions Softimage 2012).
- Thank you very much to the user "l_cymer" for his invaluable contribution to LuXSI.
- Updating the shaders.
- Added shader libraries for all these x64 versions of Autodesk Softimage.
- Added GUI option to enable debug messages.
- Deleting the option "Hybrid" in "Engine type", not to create confusion for users.
- Version 1.0.0:
- Updated syntax to LuxRender 1.0
- Scenes created with earlier versions may not work properly with this version.
- Revised the code for 'area light'
- The 'area light' is now controlled with the global panel, except 'scale' which uses the object's interface 'light'.
- Started support particles
- Supports 'pointclouds', exporting the LuxRender 'sphere' primitive
- for each particle.
- Currently missing support for animation, so exports only frame by frame.
- Redesigned user interface.
- New distribution options, preparing the interface to support animation
- and particles.
- The 'Path to LuxRender' option should only specify the folder where the
- LuxRender binary is located, not the ".exe" itself.
