Well, I created a new project and reimported the DEM files. Then exported the height map with new ini settings and imported it ontop of the current project. Almost all the airfields need to be re-leveled (I dont use the function in TE, doing it manually), the mountain top missile sites need re-locating, etc. etc. Basically back to square 1 But the transformation was huge, the sight of huge towering mountain peaks are awesome..
Although I must say, with a HeighScale of 20, you wont have the low range of height steps. Some of the lower hills seem to be much smoother and less intimitading..
Also, think twice about using the TE Smooth Height function, it kills the sharp countours of mountains and flattens volcanic lake beds, and so on.. the terrain looks much better in rough form IMHO.
