Whatever happened to that feature of Terragen? It was in an early version and was sort of the hallmark of the product, that you could literally use the mouse to sculpt terrain... Now with everything being procedural, it seems that the only way to get a terrain of a specific design is to export it somehow, go into photoshop, create new grayscale bumps and valleys, and import it back in somehow...
Will that other feature ever come back in some form?
