The following are plugins I have developed for Autodesk Softimage which I feel may be helpful to others. All have been used in production environments.
ScriptEd (XSI C++ Plug-in)
SciptEd is an alternate script editor for SI with a few extra features.

Some of the functionalty mentioned above is not yet present in the latest release.

ScriptEd may be downloaded here, (right click, 'save as..').

Please go through the ~readme.txt file for post-installation instructions. Do remember that if you're updating ScriptEd from an older version you need to uninstall ScriptEd from XSI and also delete the ScriptEd directory from your system (if XSI fails to do so)
Note: There is a chance that Autodesk will not port over the current threads in the XSI forum to the AREA. If that happens, I will most likely start a new ScriptEd thread in the AREA.
 
Mapify (XSI JScript Plug-in)
Mapify allows management of render mapping (texture baking) across multiple objects

Click Image for a bigger version
  • The RenderMap properties of multiple objects can be controlled very easily
  • Any object added to the list which doesn't have a RenderMap property is automatically given one
  • Three properties can be set across selected objects from within the UI
  • Advanced properties can be changed by selecting objects and hitting "View RenderMap PPG"
  • All images are put in sub-folder named after the object the RenderMap belongs to under the path given by the user
  • Mapify allows the user to automatically set as a constant material the render mapped images that have been generated after the mapping process.
  • Mapify also ships with a function which allows the map generation to be done using xsibatch. This is useful if you would like to RenderMap across a render farm. Please read the help doc (by clicking on the "?" icon in the top right of the Mapify PPG) for more information.
Mapify may be downloaded here, (right click, 'save as..').

Please go through the help file for detailed usage.You can access the help file by clicking the little "?" icon in the top right of the Mapify PPG. Do remember that if you're updating Mapify from an older version you need to uninstall Mapify from SI and also delete the Mapify directory from your system (if SI fails to do so)
 
Smedgify (XSI VBScript Plug-in)
Smedgify is a submitter for the Smedge render management software

Click Image for a bigger version
  • Allow submission of passes as separate jobs
  • Also allows submission of multiple passes in a single job if the frame range, priority and packet count is the same for each selected job
  • Allows submission of FX Trees (show)

This was specifically written for Lola Post.
If you use this you will need to make your own Smedge job module for FX Tree submission. You will also need to look at the code to adjust the paths to pools.ini (which is used to generate the list of active pools in your farm)
Smedgify may be downloaded here, (right click, 'save as..').
