About this Mod

Hardcore Darkness (Fabric)

Hardcore Darkness recreates the pitch-black nights and fog tuning of the classic True Darkness mod for modern Fabric. For shaders, I suggest tweaking Complementary as this mod doesn't affect them.

Fireflies!

Features

Configurable darkness per dimension plus optional moon phase handling (config/hardcore_darkness.toml).
Adjustable Nether and End fog multipliers to keep those dimensions oppressive.
Supports Distant Horizons!

Install

Requires Fabric and Fabric API.
Optional UI: add Mod Menu and Cloth Config to tweak settings in-game.
Place the built jar in mods/ on the client. Servers never need it.

Server lagging with Hardcore Darkness – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Hardcore Darkness consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
