Simple mod to place lab tiles on newly explored sections of the world completely devoid of water, decorations, stones, ores, water, crude oil or anything else not suitable for those in lab coats.
Sets new areas of the world as you explore to the gray checkerboard as seen in various FFF updates.
Does not clear or impact existing areas of the game world. eg your existing factory or outposts won't be modified. Existing large areas will remain as they are.
Upon mod removal, or if you temporarily disable the mod, the existing laboratory floors remain in place and later further exploration will trigger normal terrain generation complete with ores, trees and biters as per usual map settings (or whatever other mods, such as RSO, have applied)
