I Think The First Lines In The Script Tells You
Here's What It Says:
-- USE: Generates a RIB file (and a shadow RIB file) for rendering in the Renderman format
-- NOTES: Running this script will produce two RIB files in the renderman subdirectory. Render
-- the shadow RIB first before rendering the main RIB. The output of the render should produce
-- a SHD file and a TIF file.
Edit: I Tried Putting It In A Folder I Just Made Called 'renderman' And Then Tried Running It. It Created 2 Files In The Folder Like It Said It Would, But It Also Crashed My Game
