About

PSX-Core Shader in a snowy forest

A Minecraft shader that recreates PS1 visuals. Features:

  • Ordered dithering
  • 5-bit per-channel color quantization
  • Gouraud shading with banded light levels
  • Vertex snapping
  • Affine texture mapping
  • Fog (scary)

Most of these are configurable via the shader settings! Only thoroughly tested with Iris on 1.21.11 (works on older versions too, please report bugs). Works with DH & Voxy.
