Hi spec24,
Make sure your region & camera lock triggers encompass the entire area, from below the lowest point on your terrain(/walkable area). I believe the region trigger also has a fog of war setting.
Ah! Ok - so some important information missing in the previous posts. Just turning on Hide Shroud in Edit Level Data is not enough - though it seems like it when you're developing the map. You also have to put in a region trigger! Got it. Will give it a try now. Thank you!!!
