Maps made with the undocumented map editor from the demo could be used just like that in the demo, the full game and it's extension pack WE/MI.

Rob made the very useful mapflattener. This tool zero-ed all heightdata in maps. After a re-texture job, his flat Totomi map became a fresh 'green' template. Much easier to create new work on fresh paper instead of using old yellowpages and phonebooks. Almost all maps I made after the release of Robs tool were made from this template. Green was shipped in the expansion pack and became known as iron board.
