Shader Patcher
by excederus
Shader Patcher, a Client-side only utility for Fabric, Forge and NeoForge, adds mod support to shaderpacks in the Iris and Optifine formats.
What it does
The mod attempts to patch a shaderpack so that blocks, items and entities from other mods are recognized by it. Patching works through mapping and transform files that identify modded blocks, items and entities and point them to the matching properties file, using each entry's ID field. Modpack developers can add further patches by bundling files into their config directories, and existing shaderpack properties files are reused when they already cover a mod.
Coverage is limited. Patching searches for vanilla blocks, items and entities, so new categories cannot be invented, and the bundled support covers only the blocks, items and entities of the mods the author added. Iris and Optifine shaderpacks in their standard formats should, in principle, load with Shader Patcher applied, and the same applies to Euphoria Patches, where a Minecraft restart can be necessary based on which Euphoria release is in use. Fabric API is required, and the mod is open source under the GNU Lesser General Public License v3.0 or later.
Files are published for 1.19 – 26.3 across Fabric, Forge and NeoForge, with the 0.4 beta as the latest build on each loader.
