VoidGenerator (obsolete)

[NiLSPACE]

That should be pretty easy to add though. Something like this should work:

function OnChunkGenerating(World, ChunkX, ChunkZ, ChunkDesc)
	-- Other code
	
	local ChunkSpawnX, ChunkSpawnZ = math.floor(World:GetSpawnX() / 16), math.floor(World:GetSpawnZ())
	if ((ChunkSpawnX == ChunkX) and (ChunkSpawnZ == ChunkZ)) then
		FillRelCuboid(0, 15, 8, 8, 0, 15, E_BLOCK_STONE, 0)
	end
end

This will create a floor of stone blocks on the spawn chunks at layer 8.
