Spawn-Proof Planner

Import a Minecraft schematic and the Spawn-Proof Planner finds every surface where hostile mobs can spawn, then plans how to stop them. Simulate block light from torches, lanterns, glowstone, and more, adjust spacing and mounting height, mix light sources per surface, fill large voids with geometric floating light lattices, or cover surfaces with non-spawnable blocks such as carpet and slabs. Preview coverage live in 3D and on a layer by layer heatmap, then export a .litematic overlay with a materials list.
