Current questions and answers regarding the map editor.

How do I create a dialogue scene in the Dungeon? The map has an underground, but it cannot be opened in the DialogScene window - the ShowUnderground function is blocked

In the map's cutscene folder  (which you previously created in the data folder) there should be a map.xdb file. Open it and find the attribute, then set its value to 1 for the underground instead of the default 0 for the surface.
