World Machines, a procedural landscape generator, was used to create the terrains in Tribes: Vengeance.
This archive contains various World Machine data files used in the creation of some (but not all) Tribes: Vengeance maps. These are not supported in any way. They're offered simply as examples of what you can do using World Machine. These are intended for advanced mapmakers only.
Please see the readme.txt file for further instructions for using World Machine to create terrain for Tribes: Vengeance.
