Worldbuilder (Red Alert 3)

The Worldbuilder is the official map editor for Red Alert 3. Like its predecessors, maps were created in an in-engine environment, allowing full control over the landscape. It is incompatible with versions 1.04 and below of Red Alert 3, as well as Uprising.

A special, more potent version of the Worldbuilder was made specifically for version 1.12 and was released separately from the Mod SDK. Using both Worldbuilders at the same time is possible.

Black terrain error
If maps created in Worldbuilder have been installed in Red Alert 3 version 1.04 or lower, the main terrain will appear black, while hills and regular objects appear correctly.
