Model Map

 This turns your minimap into a model. It will only show walkable tiles. This can be good and bad but I personally like it more than the normal map.

Just download it, open it with 7zip
Replace all the files in

C:\Program Files (x86)\Red Stone\data\Scenario\Red Stone\Map
and
C:\Program Files (x86)\Red Stone\data\Scenario\Red Stone\Map\Expansion
