Petroglyph's Map Editor lets you view and edit maps for Petroglyph's games.
Note that the standard PG map editors for EaW and FoC have the undesired behavior that they delete shaders and the MT_CommandBar files on startup.
I patched their map editor to disable this behavior. Download the patched executables here and copy them over the installed Petroglyph Map Editor (be sure to backup the original).
The patches were made by replacing all calls to DeleteFileA in the executable with calls to GetFileAttributesA, a read-only operation that takes the same arguments as DeleteFileA.
