Just to be clear (again, I've never worked with the editor): Is bumpiness set globally for the whole scenario (with, I guess, different terrain types scaling along with it), or is it set separately for individual terrain types (clear, woods, etc)? Or is it something we'll have to paint by hand across the map? If want to update, say, ten scenarios all using the same THM, would we have to change each scenario's values individually, or is it enough to change the THM once?
