Platinum Arts Sandbox - Free 3D Game Maker Forum

These are probably the most annoying thing about Sandbox:

gallery/image_page.php?album_id=3&image_id=196

That isn't mine, but it illustrates what I'm talking about. If you try to edit anything once you do the H transform land thing, Sandbox creates these stupid little 'shelves' that pop out of your hill. I've tried using Q to edit the corners but it doesn't seem to work (the more area you modify, the more shelves you get). How do I avoid/fix these? I've been using Sandbox for many years but condensed my experience is relatively low. Maybe I'm doing something wrong.

Anyway help is greatly appreciated

generally, I think you can avoid that problem by having consistent grid sizes when using heightmap mode. Remipping might fix some errors, but your best bet is to just fix all of them, one after another.
