Have you wanted to be able to edit the map2 and or the map3? Well here's your chance! I managed to figure out how to do it within WorldForge!
WF4map2.exe and WF4map3.exe can edit the map2 and map3, respectively. Granted these aren't really all that put together that well, but it can get the job done. As of yet, you can't freeze or melt statics into these maps, but that will be added in the near future hopefully (still working on it).
Each program will ONLY work with the map it is designed for, so you can't edit the map0 with the map2 program. Please keep that in mind.
WorldForge 6.5
This require WorldForge 6.4 support files. Place them into that folder.
