Your terrain's "base" altitude is higher than 0. In Terragen 0.9 there was no "planet", so you never saw your terrain in context of a global 0-altitude planetary surface, as you do here. So if you have the lowest part of your heightfield at say 500 meters, when you load it in to TG2 it is displaced to that altitude from the 0 altitude surface of the planet. If you simply place your camera up on top of the heightfield, you will see it can look very similar to Terragen 0.9. If you want to maintain the *correct* altitudes (as this appears to be from a DEM), you should not adjust the height, but simply move the camera. If you'd rather adjust it so that the base altitude of the DEM is the same as that of the planet, you would use the Heightfield Adjust Vertical operator.
