Hello. I need minLevelSnow on mountians in 1.7 becouse i 8 bits high map snow are very rate on montians. Can you add that? Thanks.

You can use the BiomeTemperature setting for this, although it seems broken at the moment. Edit: in custom biomes it works fine.

Snowfall is controlled by Minecraft (not the initial snow generation) so we have to make sure that snowfall and snow generation work the same. Minecraft uses the biome temperature for the snowfall, so we'll use that too.

Closing this, as you can use BiomeTemperature to control the snow height.
