About this Mod
This mod in basic makes the fog look INSANE. Look at the images to find out what it looks like as well.
--The Fog Itself--
- Mainly a shader that i made for myself a long time ago
- Its like perlin noise but cloud edition
- The fog also affects the sky, making it a different color if you use the color hex editor in the config.
--The Config--
- In the options menu, theres a config button in the bottom corner to config the fog and its height, and color as well
- You can change the fog color to any hex color code you know
- The height can go from -(the biggest number you can think of) and up to +(the biggest number you can think of)
- Theres also a custom RGB mode so you can see rainbow fog... yummy.
- Theres also a keybind (R) you can use to turn off or on the shaders (you can also edit the keybind in the keybinds menu as well)
