Navigation

Unreal Engine supports runtime navigation generation. However, a flag needs to be set in the projects setting.

Navigate to Edit > Project Settings > Navgation Mesh > Runtime > Dynamic

This will automatically regenerate the navigation on runtime generated dungeons. Be sure to have a Nav Mesh bounds Volume large enough to wrap the whole dungeon. There is an example in the quick start guide to automatically wrap the navigation volume around a dungeon after it has been built.
