FOSS gamedev and creative worlds

Hi there - i played with the mgv7 parameters and created a quite beautiful formed world.
But there are many "blank" biomes and i am wondering what causes that.
Is there a specifc value which should stay untouched?
Or might this be a bug?

It is not a broken/missing biome by itself - i am sure about.

Can you post your noise parameters?

Okey, here[removed] is the map_meta file.
(I did not use the minetest.conf)

Weird i can't see why, biomes should remain unchanged whatever the terrain shape, there isn't a bare stone biome in MTGame.

I just experienced that it doesn't happen without ethereal - i didn't await this as a potential troublemaker 'til posting here so i didn't mentioned it. Will adjust the parameters there to see what happens... . :o

Okey, there is at least one biome missing - maybe it is actually my fault and i pressed 'd' one time too often in vim or something - sorry for that - i will write again if i am wrong (again) and cannot find an actual solution but i guess for now i know what's wrong^^

Hi again - i finally figured out that i only can get rid of those stony biomes when setting the heat+humidity to zero in one biome.
