Water Depth Fog
by Canser_PTR_
Water Depth Fog changes the underwater fog so it grows darker the deeper a player swims below sea level, ending in near-black at depth.
What it does
The fog color shifts from a light blue-green tint near the surface toward near-black at depth, and the near and far draw planes pull in as the player descends, so visibility shortens the deeper the dive. Depth is measured from sea level at Y=62 by default, and the effect reaches full strength at a configurable maximum of 60 blocks below that line. Between the surface and deep values the change is a smooth linear blend, without hard cutoffs or flickering.
The mod is purely visual and runs on the client alone, so only the client needs it and servers do not. It has no gameplay effect, so it can be added to a pack without changing mechanics, and it works alongside water pressure or damage mods without requiring one. Files are published for NeoForge 1.21.1 only, with 1.0.0 as the latest file, released on 2026-07-21 on the beta channel. The license is All rights reserved, so the mod is not open source.
Key features
Depth-based fog darkening
Underwater fog darkens and its draw planes close in as the player swims deeper, instead of staying the same at any depth.
Configurable surface and deep colors
The surface and deep fog colors and the near and far plane distances can each be set at both ends of the blend.
Adjustable sea level and depth range
The reference sea level and the maximum depth of the effect are both configurable, with defaults of Y=62 and 60 blocks.
Sable submarine exclusion
With the default setting, the effect is skipped inside Sable sub-level interiors, so a dry, lit submarine cabin shows no deep-ocean fog.
Client config file
All options are stored in the client-side depthfog-client.toml file, and the effect can be toggled on or off.

FogRule is a NeoForge 1.21.1 mod under the MIT License, open source, that runs on client and server.

What the author says
Vanilla's underwater fog looks the same whether you're 2 blocks or 200 blocks down. Depth Fog fixes that: the deeper you swim below sea level, the darker and closer the fog gets, until the abyss actually feels like the abyss. This is a purely visual, client-side mod — no gameplay effect, no server dependency, safe to…
