I need 2 terrain types for Battle for New York: park to replace desert, and concrete to replace grassland. Replacing desert with grassland and forest graphics would be fine, but I'm not much good at making C&P work look good and the terrain files are confusing to work with. If somebody could make these 2 conversions, I would really appreciate it.

I've heard there are some problems with using the LM graphics for base terrains, but if it's possible I would like to have 2 versions of "desert," one with trees and one without. But that's no big deal, I can go without it.

I can give detailed suggestions if somebody is willing to help.

What kind of cement are you needing? Like sidewalk kind of cement or road/driveway kind of cement?

EDIT: and could park replace Grassland instead? It might be easier that way, if I do it.

Basically just an open paved area with no buildings.

That might be possible for the first version, but I need rubble (forest) to be on concrete and roads (plains), so that leaves desert. And I don't want to have to redo the map for a temporary terrain switch.
