Can you please add a feature (toggleable or mandatory, that's up to you) for the plugin to generate each column of terrain with the "vanilla biome" that most closely corresponds to the values the admin selects for temperature and humidity in the biome settings file? This will ensure correct weather and "best possible" foliage colors for vanilla users.

For example, if I make my extreme hills cold and snowy, I want the weather there to be snowy. So even though hills would generate, you could use an ice_plains vanilla biome for that region.

ReplaceToBiomeName? Or do you mean something else?

Replace this biome to specified after the terrain has generated. Warning: this will cause saplings, colors, rainfall and mob spawning to work as in specified biome. For example, if you have set ReplaceToBiomeName to Jungle inside SwamplandBiomeConfig, the swamp biome will have the colors, rainfall and mobs of a jungle.

This doesn't affect the initial generation. If you set ReplaceToBiomeName to Ice Plains for a Jungle, the Jungle won't be covered with snow initially. However, during storms snow will fall in this biome, so during the first storm, snow will cover this biome.

I won't add ReplaceToBiomeName:Auto for now. Currently I'm already busy with other suggestions.

Oh, so that's what that does? I just write "Ice Plains" in there (for the situation of the above example?)

(Anyway, even in that case it's still a useful feature, just not necessary. Perhaps enable if ReplaceToBiomeName is set to 'Auto' or something...)
