Foglands

Foglands replaces the oppressive purple particle mist in Valheim's Mistlands with a more pleasant, atmospheric fog system. The thick, motion-sickness-inducing mist is replaced with a lighter gray fog during the day, while a Time-Based Fog system brings back denser fog at night - keeping your Demisters relevant and the biome challenging.

I made this mod because it's one that I want for my next playthrough.

Installing the mod on the server requires all clients to have it installed. It will kick them if they don't. It will also sync the configurations down to clients. Can be used client only.

Why Foglands?

The vanilla Mistlands mist has been widely criticized for:

• Causing motion sickness and eye strain
• Being too visually oppressive (can't see anything)
• Making the Wisplight feel mandatory just to navigate
• Performance issues from the heavy particle system

Foglands attempts to address all of these while preserving the atmosphere that makes Mistlands unique.

Features

Pleasant Daytime Fog

• Replaces the purple/blue mist with a neutral gray fog
• Significantly reduced particle density for better visibility
• Smaller, more transparent particles that feel like natural fog
• Better performance in Mistlands due to reduced particle count

Time-Based Fog System

The fog intensity changes throughout the Valheim day cycle, synced with vanilla's day/night timing:

*Based on vanilla's 30-minute day cycle and 1.5 hour transition setting

Weather Integration

Bad weather makes the fog thicker, just like other biomes have weather-based challenges:

Weather effects stack with time-of-day effects. Avoid it if you can!

Demister Relevance

With Foglands, your Demisters shift from "mandatory to see anything" to "the tool that beats the dangerous night fog":

• During the day: Demisters are optional - the fog is light enough to explore without them
• At night: Time-based fog brings back dense fog, and Demisters push it back just like vanilla
• Gameplay detection: During daytime, enemies don't get the "mist" detection bonus; at night they do (unless you're near a Demister)

This means you can:

• Explore freely during the day without feeling forced to carry a Wisplight
• Plan dangerous activities for daytime
• Use Demisters strategically for nighttime operations, base lighting, or aesthetics instead of need

Configuration

All settings are server-synced and can be found in BepInEx/config/Azumatt.Foglands.cfg.

Customization Examples

"I want even clearer daytime fog"

• Lower Day Fog Alpha to 0.15-0.20

"I want more challenging nights"

• Increase Night Fog Multiplier to 3.0-4.0
• Increase Night Fog Alpha to 0.6-0.7

"I want quick transitions (short dusk/dawn)"

• Set Transition Duration Hours to 0.5

"I want gradual transitions (long dusk/dawn)"

• Set Transition Duration Hours to 3.0-4.0

"I just want vanilla fog with gray color"

• Set Night Fog Multiplier to 1.0
• Set Night Fog Alpha and Day Fog Alpha to the same value

"I don't want weather to affect fog"

• Set Enable Weather Integration to Off

"I want storms to be terrifying"

• Increase Storm Fog Multiplier to 2.0-2.5

"I want a different fog color"

• Adjust Fog Color Red/Green/Blue values (0-1 range)
• Example: Greenish fog = R:0.4, G:0.5, B:0.4

Performance

Foglands is designed to be more performant than vanilla:

• Daytime: ~40% of vanilla particle emission = significantly better performance
• Night: Up to ~100% of vanilla emission = similar performance
• Max particles: Reduced from 4000 to 2000
• Particle lifetime: Reduced from 5s to 4s

The performance savings come from the particle system changes.

Compatibility

• MistBeGone: Since this changes how the mist looks, and a little how it works, it should be fine to use with MistBeGone. The "Disable Particle Mist" configuration option in this mod is ignored if MistBeGone is installed at the same time. This ensures the mist hiding is controlled by MistBeGone.
• Wisplight Range Mods: Yes, works fine with them. The mist doesn't change function.
• Mods that change the mist: Mods that directly change the mist or particle system might conflict. I have not tested with any, but it's possible.
