So, I'm making a nether map that involves the use of superflat world presets. The ground is completely netherrack, and there are lava lakes spread across the map. I'm running into a problem though, the lava lakes don't spawn often enough for me and I want them to be more common. Here's the base preset I'm working off.
Now, this just creates a superflat world with lava lakes here and there, not that common. Now, here are a few things I tried to make lava lakes more common.
2;1x7,30x87;8;lava_lake(chance=100) 2;1x7,30x87;8;lava_lake(size=10 distance=0)
None of these seemed to increase the probability of a lava lake spawning. So, how can I increase the probability of lava lakes spawning?
