Description

Resource pack shaders that keep working under shader packs.

Five armour sets under the Complementary shader pack at sunset

A resource pack can change how Minecraft draws things by shipping its own shaders: glowing armour, animated textures, shapes that move. Turn on a shader pack and those effects disappear, because the shader pack draws the world with its own programs.

Stitch brings them back. Packs that use Stitch describe each effect once, and this mod weaves it into Iris's or OptiFine's shader pack programs as they load, shadows included. Install it, keep your shader pack, and the pack's effects stay.

The same scene three ways: vanilla with the effects; a shader pack without Stitch, the armour plain; a shader pack with Stitch, the effects back

Install

Put the jar in your mods folder, beside your shader mod:

Loader Shader mod Minecraft
Fabric Iris 1.18.2 to 26.3
Forge OptiFine 1.18.2 to 1.21.11, wherever OptiFine runs on Forge
  • One jar covers every loader and version above.
  • It does nothing without a shader pack: in vanilla, or with shaders off, the pack works on its own.
  • Client only. Servers don't need it and don't check for it.
  • No other mods are needed (no Fabric API).

What you get

  • Effects under shader packs: colour, glow and animation from the resource pack, inside the shader pack's own lighting.
  • Shapes too: packs can move or hide parts of a model (flared skirts, floating plates, wings made from a chestplate), with shadows that match.
  • Safe to leave on: an effect a shader pack can't take is skipped for that program alone, with a log line saying why. The shader pack always loads.

For pack makers

Stitches are written once in GLSL against a fixed interface, and a GitHub Action builds them into the pack for every release from 1.18.2. The specification, examples and the Action are on GitHub.
