WorldEdit was the original name of EditWorld. It was made by Pumpkin Studios as a tool to create and edit maps used in the original release of the game.
EditWorld application
After Warzone and related assets were released as open source, WorldEdit was maintained by the community (particularly NEWST) and renamed to EditWorld.
Documentation
Without these people, the documentation you see here would not have been possible:
Shang – Original Edit World FAQ, and several 3rd party add-ons, plus his first try at adding custom tilesets
HB – For his amazingly easy TMLink program that has helped all of us add custom tiles
Maynard – For his help in allowing explaining EditWorld features and lots of help with the documentation project
Striker – He checked the documentation and created some really cool height maps
Troman – Proved us wrong on lots of things, and helped us understand some of the more obscure features
Alex McLean – For his support when this project was started
Zydonk – for creating some of the tutorials
Lav_Coyote25 – For huge contributions to the Warzone documentation projects
This is a very old map editor. Use the new map editor instead: FlaME
