NeoForgeClient required, server optionalAll rights reserved1.21.1

What it does

Players can load their own shaderpacks through the Iris or OptiFine shader system. The mod adds commands such as shaderpack off to turn shaders off without opening the video settings, and it auto-detects whether Iris or OptiFine is present. Shaderpack files are placed in the .minecraft/shaderpacks folder.

The mod works in singleplayer and on multiplayer servers, and it only changes the local view of the player who runs it. It uses reflection instead of hard dependencies, which the author describes as a way to improve version compatibility. Iris Shaders and Sodium are required, and Iris is recommended alongside Sodium. Files are published for NeoForge on 1.21.1 only, with the latest file 1.0.5 dated 2026-08-20. The mod is released under All rights reserved and is not open source.

Key features

  1. Shader toggling by command

    Commands such as shaderpack off switch shaders off for the local player, with no need to change the video settings.

  2. Iris and OptiFine detection

    The mod identifies whether Iris or OptiFine is installed and adapts to the shader system it finds.

  3. Local-only effect

    Changes apply only to the local view, so the shader state of other players on a server is not affected.

  4. Custom shaderpack folder

    Shaderpacks placed in the .minecraft/shaderpacks folder can be loaded through Iris.
