Oh right... that isn't particularly well designed. I probably assumed no one is using it. I'll put those ideas in next time I go into terrain builder. Let me know if you have any more ideas.

Loving the new mountain complex design! While mapping it out, I noticed that it could probably benefit from at least one dedicated medical building. I think setting the back half of the research/lab block to the medical variant of the cargo houses would be a good idea. That section is directly connected to the main roadway inside the building, which allows for quicker ambulance responses. Being next to a water tank is also good for medical purposes.

Speaking of vehicles, it may be a good idea to code some roads into the back half of the base. I really don't know how that works in Terrain Builder, since my own terrain projects haven't gotten very far, but it would allow for enhanced usage of the newly vehicle-accessible locations deeper inside the base. Experimenting with on-foot AI, I would set groups to File, and they could mostly navigate the sections with roadway, but they had trouble deeper in, even with mazes of waypoints. I think adding roads would help this too. Maybe the roads could be invisible? Again, I don't know how they work in Terrain Builder.

Awesome, and thanks for the feedback. This is an illusion of a large interior space made of a bunch of terrain objects and not a real building interior, I think there's going to be some problems with ai pathing. Considering arma limitations I think it works a player or pvp oriented space. Will look into the other suggestions.
