Current questions and answers regarding the map editor.

When exporting, the game places files from an external directory into the archive with the map. It does this automatically.

There are three non-functional (intended for campaigns) artifacts in the game: Frida, Princess, and Ring of the Shadowbrand; I don't remember what it was called before. I think Markel was hunting for it. The stats of these artifacts, as well as their models, names, descriptions, and icons, can be freely changed (data.pak/GameMechanics/RefTebles/Artifacts.xdb and the files linked to it).
