One thing that really bugs me when walking around in-game is the frequency with which deserts spawn. I've poked around in the game files, but I can't seem to find what I'm looking for. What I want to do is modify(reduce) the rate at which deserts are encountered.
The map_meta.txt file in ~/.minetest/worlds/ contains a line "mgv6_freq_desert = 0.15", but changing the value doesn't seem to affect anything.
Any help pointing me in the right direction would be greatly appreciated.
