Depth Fog (Forge 1.20.1)

Client-side mod. Underwater fog gets darker and closer the deeper you dive.

• Tracks camera Y vs. sea_level (default 62).
• Blend factor = (sea_level - camY) / max_depth, clamped 0..1 (default max depth 60).
• Fog color lerps from the vanilla water tint to deep_color (near black).
• Fog start/end lerp from vanilla values to deep_fog_start / deep_fog_end.
• Only applies while the camera is actually in water, so an air-filled sealed hull keeps normal visibility.

Config: config/depthfog-client.toml

Build

Requires JDK 17. This folder has no Gradle wrapper (no jar can be bundled), so either:

1. Copy gradlew, gradlew.bat and the gradle/ folder from the official Forge 1.20.1 MDK (https://files.minecraftforge.net), then run ./gradlew build, or
2. With Gradle 8.1.1+ installed: gradle wrapper --gradle-version 8.1.1 && ./gradlew build

The jar ends up in build/libs/depthfog-1.0.0.jar. Drop it in mods/. Test in dev with ./gradlew runClient.

Easiest: let GitHub build the jar

1. Create a new GitHub repo and upload this folder's contents (including the hidden .github folder).
2. Open the Actions tab -> Build jar -> wait for the green check.
3. Click the run, download the depthfog-jar artifact, unzip it, and put depthfog-1.0.0.jar in your modpack's mods/ folder.
