Dependencies:

  • Fabric API (1.21.4+)
  • Cloth Config API (1.21.4+)
  • Mod Menu (1.21.4+) Optional as of version 1.3.2

These can also been found in the versions tab.

Features:

This not only works with UI elements like buttons or sliders, but also GUI elements like the inventory screen. A customizable keybind (default F10), can be used to change the mode in-game, so you can have a seamless experience and a simple config screen for easy customization. Im my opinion, this mod looks best in 1.21.4 and 1.21.5, after 1.21.6, Mojang changed the rendering engine, so the dark effect won't look as good, but it's still decent.

Frequently Asked Questions

Does Let There Be Dark need to be installed on the Minecraft server?

No. Modrinth marks Let There Be Dark as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does Let There Be Dark require?

Use a file for fabric and your exact Minecraft version. Supported versions include 1.21.8, 1.21.7, 1.21.6. Files for different loaders are not interchangeable.

Let There Be Dark is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
