About this Mod
Using the new "Enviroment Attributes" added in 1.21.11 (Mounts of Mayhem update) I thought it would be cool to add more unique fog to some biomes by changing their fog color, strength, and sky color.
Warning: This mod might not be too compatible with other worldgen mods that change the oringinal biomes in any way. This is because the datapack overides the vanilla ones just for the fog. If you know another way then put it on the github.
Biomes Changed
Check the Gallery to actually see the changes.
- Pale Garden - Increased Fog by Alot
- Deep Dark - Increased the Fog and Changed the Fog Color to a Dark Teal
- Dark Forest - Moved Fog a bit Closer
- Swamp - Increased fog, Changed the Fog color to a Murky Green, and Made the sky a bit greener
- Mangrove Swamp - Increased fog, Changed the Fog color to a Dry Green, and Made the sky a bit uglier green
- Jungle - Increased the Fog (also for the subiomes)
- Desert - Changed the Fog Color to be a bit Yellower and the Sky to be a bit desaturated
- Badlands/Mesa - Changed the Fog Color to be a bit Oranger and the Sky to be a bit desaturated and teeny bit red. Sub Biomes were also changed to have this change.
- Mushroom Fields - Changed fog and sky color to be kinda purple and made it a bit thicker
- Taiga - Fog is a teeny weeny bit denser (also for the subiomes)
- Snowy Taiga - Fog is a bit denser than the taiga, the sky and fog colors are a bit bluer
- Groves - Fog is a bit denser, sky and fog colors are a bit bluer. (groves are the snowy taigas on mountains)
- Savanna - Sky and Fog colors are a bit purple/orange-ier
Things I might Add/Change Later:
- Sub Biomes for the Savanna and maybe some others I missed
- Mountain Biomes
- Snowy/Icy Biomes
- Maybe Lush and Dripstone Caves
- Unique Nether Fog distances for each biome
If you got any ideas post them on the github like the report issues button to the right probably, or dont its a annoying process to log in. If you want a cool world gen datapack with unique fog than use Clifftree, it's super good. ok anyway have fun
