Although the inital release is Macintosh only, I expect to have the Windows version working by March 17th, just in time for a pint of Guinness!
From the ReadMe
Using Launch Mode3:
This script saves the current scene, clears Layout, and begins rendering
the current scene in LWSN Mode 3. For more information on Mode 3, see the
section in the documentation included with Lightwave called "Rendering Without
Lightwave"
1) Select Launch Mode3
2) The panel is preset with the render options set in the scene. You can choose to
change them here. These options include the Start Frame, End Frame and Frame Step.
3) Choose an alternate version of LWSN to render with, or leave the default (LWSN.exe)
4) Choose to Render Immediately or generate a command file. If you render immediately
Lightwave will clear the scene, and launch the external LWSN application. If you
choose not to render, a command file (.bat file for Windows) is created in the
Lightwave Programs directory.
