📋 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.

Usage and configuration

Select the Flat mode of the Terrain Tool.

Press F2 to turn on the mod, F3 to turn it off and SHIFT+F2 to turn on the "Revert Modifications" mode.

Press F9 to create a large "tangent terrain" (a flat surface that follows the planet's curvature) at the player's position.

IMPORTANT: When enabling/disabling the mod or changing the "method," you must unequip and re-equip your Terrain Tool for the changes to take effect.

You can modify shortcuts in the options.lua file. Read comments at the beginning of the file.
