http://www.doomworld.com/idgames/?file=combos/j5_wfx.zip I'm not sure how to go about this, but I want to edit this into a mod I can just apply over a map through command line/drag and drop without having to rewrite the map. I'm not working on a map I just think it would be nice to be able to apply a darker atmosphere to old maps whenever I'd like. Sorry if this is painfully dumb. Thanks!

The demo link on the first page isn't working for me, it just keeps redirecting to http://www.filedropper.com/
