ForgeOculus
by Peak885
With ForgeOculus installed, Forge players can load Iris and Oculus shader packs on Minecraft 1.21.1 through a rendering bridge built for that version.
What it does
ForgeOculus is a port of the Iris and Oculus shader pipeline for Forge. Its rendering bridge lets standard Iris and OptiFine-style shader packs run in the 1.21.1 Forge environment, with the goal of a stable modern pipeline for realistic lighting, dynamic shadows and related effects. The mod is written for 1.21.1 only and is published for Forge alone.
The mod needs Beddium, a library that supplies functions the rendering bridge depends on, so Beddium must be installed alongside it. ForgeOculus is client-side only: only the client needs it, and a server can run without it. Its code is open source under the GNU Lesser General Public License v3.0 or later, and its public source code is available.
Key features
Standard shader pack support
Shader packs in the standard Iris and OptiFine-style format can be selected from the video settings menu.
Efficient graphics card use
The rendering code uses the graphics card efficiently while shader effects are drawn on screen.
Modpack-friendly rendering
The rendering code is kept separate from the core game so that it can run alongside large modpacks.
Video settings integration
Once the game is launched, favorite shader packs are chosen in the video settings menu like other shader options.

How it compares
Beddium is the library ForgeOculus requires; it is client-side only, open source under the GNU Lesser General Public License v3.0 only, and published for Forge 1.7.10, so it does not cover 1.21.1. Iris & Oculus Flywheel Compat is client-side only, open source under the CC0 1.0 Universal license and published for Fabric, Forge and NeoForge across 1.18.2 – 1.21.1, which gives it a wider loader and version range. Faster Iris Shadow Mapper [FISM] is client-side only and open source under the MIT License, with builds for Fabric, Forge, NeoForge and Quilt covering 1.20.1 – 26.3.
