color banding be gone - Remove pesky color banding from Minecraft

cbbg^/'kabij/ is a client-side Fabric mod that reduces visible color banding by:

• Using a higher-precision render target (RGBA16F)
• Applying STBN blue-noise dithering to final image

Helps reduce color banding on following:

• Smooth lighting
• Skybox
• Vignette

What it does

• Higher render precision: upgrades the main render target color attachment to RGBA16F.
• Blue-noise dithering: applies a lightweight full-screen pass using STBN noise to break up 8-bit quantization banding.

Installation

• Install Fabric Loader and Fabric API for your Minecraft version.
• Put the cbbg-x.x.x.jar into your .minecraft/mods folder.

This mod is client-only. It does not need to be installed on servers.

Configuration

In-game (recommended)

If you have Mod Menu installed, open cbbg's config screen and select:

• Enabled
• Disabled
• Demo (split): left = disabled (no dither), right = enabled (dither)

Commands

You can also control the mod using chat commands (useful if Mod Menu is not installed):

• /cbbg mode: View the current mode.
• /cbbg mode set <mode>: Set the mode. Valid modes are ENABLED, DISABLED, DEMO.

Config file

Config file: .minecraft/config/cbbg.json

Example:

{
  "mode": "ENABLED"
}

Valid values: ENABLED, DISABLED, DEMO.

Compatibility notes

• Iris shaderpacks: when an Iris shaderpack is active, cbbg is forced OFF to avoid pipeline conflicts.
• GPU support: if RGBA16F allocation fails on your device/driver, cbbg will automatically fall back to RGBA8 for the remainder of the session.
