 And if so, how can I add some bumps and lumps into the terrain, was there some erosion feature in L3DT or something? And if so, how can I add some bumps and lumps into the terrain, was there some erosion feature in L3DT or something?

 Whole point of using those step down multiples is that actual coordinates stay the same so missions are unaffected, all stuff is in same exact grid coordinates as before. When you re-sample it just adds more cells - it interpolates the new ones between the points of the old. Whole point of using those step down multiples is that actual coordinates stay the same so missions are unaffected, all stuff is in same exact grid coordinates as before.

 However when you use L3DT to increase the size of your heightfield, all works fine it seems but bridges or harbor objects end up in water on east end. Like when you have perfectly working bridge in 50m cell size, then you increase it to 12.5m size and the bridges east end is now in water and not land like it was previous. Who knows if this issue can be avoided using some other algorithm to increase the terrain heighfield size than L3DT's dunno. If you have no bridges or special objects, you're fine, if you have... then well, you got problems with special objects. However when you use L3DT to increase the size of your heightfield, all works fine it seems but bridges or harbor objects end up in water on east end.
