I'd like to create a map of the Rochefort-Hargimont-Nassogne-Grupont area for my Long Campaign with the Germans, for the May 1940 Ardennes battle the game is giving me. (Fictional (nearly plausible!) Panzer-Grenadier-Bataillon z.b.V. spearheads 15th Panzerkorps' advance through the Ardennes over Marche towards Dinant, meets first significant resistance in designated area)
To make an accurate map, I'd need to emulate the significant height difference of the terrain (190+ meters => 315+ height units), but I can only get up to 150 "units" high hills - thus the maximum height difference would be only about 90 meters. Is there a way to add higher hills? Can I brute-force them into the CMT files somehow?
Whilst I'm at it, is there a possibility to hex-edit the maximum map size to something larger?
