it would be great to see a feature where you could set the fog distance by biome. I believe it should be possible as a few other mods do it (e.g. Biomes o' Plenty). One application would be to provide a misty effect to jungles, swamps, highlands etc. Another application would be for servers or adventure maps to force visibility down, regardless of players' render distance settings.

Apologies if it is already possible to do this. I did look pretty hard through the configs & wiki.

Interesting idea. Would be great for swamps.
