I recently made up some new terrain, but I couldn't paint it in the world-builder, anyhow I took a fairly decent look at the Rhyes that shipped with BTS, and discovered, that you couldn't do it there either, so how did you put tht terrain into the map?
The main reason I am asking is because ever since I got the game I have been trying this, and have always run into that same brick wall, I have been through the XML, and have even ventured lightly into the SDK trying to figure out why my new terrain just does not show up in the mods I make.

Talking about the new terrain:
I've wanted to ask you this a long time ago:
Rhye, who about building windmills on swamps. The Dutch use windmills to clear swampland and making it into agreculture land.

But there aren't any marshes in the Netherlands on the RFC map.
