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)

Frequently Asked Questions

GLSL Fog server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Is GLSL Fog compatible with fabric?

GLSL Fog officially supports fabric for Minecraft 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with GLSL Fog – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if GLSL Fog consumes the most tick time.
