Changing the setuplevel.fpi for each map is a pain for testing
You can do it in the map editor by using a triggerzone with a script that changes the sky and ambience when the level starts
Just use this script as a basis for what you want.
;Artificial Intelligence Script
;Header
desc = Changes the skybox and lighting
;Triggers
:state=0:sky=skybank\natural\Pln,ambience=16,ambiencered=255,ambiencegreen=255,ambienceblue=255,state=1
;End of Script
If something compiles on the first try. Something is terribly wrong.
