About this Mod
About
Adds a new, craftable item, Terraspread, that spreads biomes across biome borders. While holding Terraspread, right click grass/dirt on the border of a biome and the biome will spread to the neareset adjacent biome.
Terraspread: Spreads a biomes border into another
Terrascrub: Restores an area back into its original biome before Terraspread usage
Sneaking while using either item will make it place precisely where the player aims rather than adjacently.
