📋 About This Mod
Flatten the terrain following the planet's curvature. Restore terraformed terrain to its original state. Create a sloped terrain with the chosen angle. Change deformation size. Paint the terrain in non-creative mode.
This mod is experimental. Make a backup of your game save before using the mod. You should test it in Creative mode first. The game may crash (especially with the "auto" method), make a save before using it.
