ShaderLab - Live Shader Editor

Tired of digging through endless shader menus and reloading again and again? ShaderLab turns Iris into a live shader studio.

Features

  • Live editor (key J): every option of your shader pack as a switch or slider in a side panel, with the world visible next to it
  • Instant preview: changes are applied automatically a moment after you let go of the slider
  • Search: find "bloom", "fog" or "water" in a second instead of clicking through sub-menus
  • Presets: save your favourite looks and switch between them with one click
  • Share codes: copy your setup as a short code and paste it in Discord. Friends load it with one click
  • A/B comparison (key N): turns shaders off and on and shows exactly how many FPS they cost
  • FPS benchmark per effect: ShaderLab measures what every on/off option costs, e.g. "Colored Candle Light: -17 FPS"
  • Uses the pack's own option names, value labels and tooltips (German language files supported)
  • Works with any OptiFine/Iris shader pack (Complementary, BSL, Photon, Bliss, ...)

Requirements

  • Fabric Loader
  • Iris Shaders
  • Optional: Mod Menu (settings)
  • No Fabric API needed

Supported versions

1.20, 1.20.1, 1.20.2 - 1.20.6, 1.21 - 1.21.11 and 26.1 (pick the file for your version).
