About
Uglifier is a lightweight client‑side mod that transforms Minecraft textures to make them ugly. It modifies textures at startup or on reload at runtime, it is fully compatible with modded textures and resource packs, and it has configurations.
Why It Exists
There is a phenomenon that occurs when you use terrible textures and then remove them after playing for a while; the Minecraft textures will look clear and crisp. Useful if you need to get readjusted to Minecraft's default texture after playing too much high-definition block game like Hytale or Vintage Story.
How It Works
Uglifier modifies textures through several steps:
- Pixel Spreading: randomly swaps nearby pixels.
- Hue Shifting: alters color tones and increases saturation.
- Noise Injection: adds some random noise to pixels.
- Color Reduction: lower color resolution for textures.
These processes make sure that every texture in the game looks terrible.
