Fog Mod (1.21.7, 1.20.1) – Cave Fog Thickens as You Go Deeper

Q: Which mod loaders are compatible?

Fog Mod is available for Fabric, Forge, and NeoForge.

The Fog Mod (1.21.7, 1.20.1) completely reimagines how fog behaves in Minecraft by introducing dynamic, responsive fog systems that react to your environment. Whether you’re deep in a cave, flying above the clouds, or watching the rain roll in, this mod creates a more immersive and atmospheric experience by enhancing how fog looks and feels.

Designed for Fabric, Forge, and NeoForge, the mod adds biome-specific fog colors, realistic weather effects, and time-based transitions all without disrupting gameplay or requiring a shader pack. If you’re looking to boost Minecraft’s visual ambiance without overloading your system, Fog Mod is a must-have.

Features:

Thickening Cave Fog:
Fog density increases the deeper you go underground, making cave exploration feel spookier, tenser, and more atmospheric especially in survival mode.
Weather-Based Fog Variations:
Fog dynamically changes based on weather conditions like rain, snow, or thunderstorms, enhancing immersion during storms.
Time-of-Day Fog Effects:
Experience beautiful color transitions in the sky and fog as you move through sunrises, sunsets, and nighttime.
Biome-Specific Fog Colors:
Each biome has its own fog tint from the purple glow of warped forests to the dry haze of deserts. Fully supports both vanilla and modded biomes.
Clear Skies Above Clouds:
When flying high (e.g. with Elytra or creative mode), the mod removes the dense fog layer and lets you see a clear, blue sky above the cloud line perfect for cinematic builds and skybases.

Why use Fog Mod?

Minecraft’s default fog system is functional but bland. Fog Mod upgrades it into a mood-setting visual tool that responds dynamically to where you are, what you’re doing, and what time it is. You don’t need a shader pack or RTX card this mod brings dramatic visual depth while remaining lightweight and fully compatible with most modpacks.

Whether you want the depths of your mines to feel claustrophobic, your forests to glow in the sunset, or your snowy tundra to look like a whiteout, Fog Mod delivers cinematic visuals with zero setup.

Ideal for:

Builders who care about ambiance
Players who want immersive survival exploration
Modpack creators enhancing environmental storytelling
