Set "defaultExtrude"to true in your BlueBridgeWG config to render all regions in 3D by default (If you don't see the config option, add it manually or delete the config and reload/restart)
Bugfixes and technical changes:
Size (area and volume) calculation for polygonal regions should be relatively accurate now
Restructured config inheritance to simplify the process of adding addons to BlueBridge
Note: You have to update Both BlueBridge Core and WG to the newest version and use a BlueMap version that supports API 1.5.0.
