I am in the process of using the "Elevation Region" Tool to change the elevation of a region within my Terrain Perimeter. I have both the top down/floor plan view up and a Full camera view up. I notice that once I have entered in a new elevation for the terrain, nothing changes automatically in the Full camera View. But if I "Clear" the Terrain and then go back in and select "Build Terrain", then My changes are reflected in the Full camera view. Is there a setting that I need to select to make sure the the elevation changes that I make take affect immediately , in real time?
