Possible to mod terrain in Imjin campaign?

Hi folks, I'm wondering if it is possible to modify the terrain in the Imjin war campaign, specifically by reducing the percentage of forested terrain in the battles? This would obviously only be for personal use in single player mode!
Many thanks,
Jay.

No promises, but you could put a modified version of MapGenerateBattle.BSF in
/Campaigns/5ImjinWar/Data/Battle/Scripts
In the GenerateBattleMap() function, lines 82-92
Code: Select all
if (region == 3) // Japan
{
if (terrain == 2)
{
open = 50;
}
else
{
open = 80;
}
}
is what controls the amount of non-wooded terrain on the map in Japan. I assume that Jayson probably used this also for Korea. To reduce the amount of woods, you would just need to increase the values for open.
terrain == 2 is actual wooded terrain.

My mistake, this should be:
/Campaigns/2ImjinWarCampaign/Data/Battle/Scripts
