+Unlimited tunnel and magma tunnel networks created from 3D noise.
+3D underground 'biomes', each with a differing mix of 2 intersecting tunnel systems, the biomes create a few dead ends.
+Mostly separate from this is a larger scaled magma tunnel network, if these magma tunnels come to surface in water, default lavacooling creates obsidian tubes.
+Optional glowing lux ore craftable with 8 glass nodes to 8 lights, lux ore also spawns in desert dungeon walls.
+You can use this with or instead of normal caves, disabling normal caves removes the lava caves and some features in the landscape.
