Latest release on GitHub

Iris & Oculus Flywheel Compat is open source. Its newest release on GitHub is 1.20.1+1.1.3a-beta, published on Aug 17, 2024.

This version only compatible with Iris&Oculus 1.7.0 and above.

TL;DR:

  • Fix issues in PBR and Parallax Occlusion Mapping.
  • Support Seus PTGI HRR 3, Shrimple, and UShader, etc.
  • Includes Flywheel in the jar file, so you don't need to install it separately.

1.1.3

  • Fix issue #146.
  • Fix issues in PBR. Normals and tangents of moving contraptions now are correct.
  • Support Parallax Occlusion Mapping.
  • Fix issue #150.
  • Replace vertex v with vertex _flw_v to avoid conflict with existing variables.
  • Include Flywheel in jar file.
  • Because some users don't use the Create mod and have trouble with the Flywheel installation, I decided to include it in the jar file.

New compatible shaders:

  • Seus PTGI HRR 3
  • Shrimple
  • UShader

There are still many that have not been tested but may be compatible.

Before that: 1.19.2+1.0.3a-beta (Aug 17, 2024), 1.20.1-1.1.3-beta for Iris 1.7.0+ (Aug 16, 2024).

Description from the author on Modrinth

Version Compatibility:
Create Version · NeoForge/Forge · Fabric
6.0.9 · 2.1.0 · ❌
6.0.0 - 6.0.9 · 2.0.5 · ❌
5.0 · 1.X · 1.X

Features:

  1. Render Create's entities using Flywheel Instancing with shaderpack enabled.
  2. Supports most shaderpacks without patching.
  3. Supports PBR.

If you have any suggestions or issues, please raise them on the GitHub issue page.

What's this?

Flywheel will disable its optimizations when you are using shaderpacks.

This mod forces Flywheel's optimizations to be enabled.

For those using shaderpack and mods depend on Flywheel, this mod can significantly improve fps.

If you don't use shaderpack, this mod has no effect. Because Flywheel's optimizations are enabled by default.

Compatibility

The shaders that have been tested are:

  • BSL
  • Complementary
  • Complementary Reimagined 
  • SEUS renewed
  • Sildurs Vibrant Shaders
  • AstraLex
  • Photon
  • Kapa
  • Nostalgia
  • Rethinking Voxels
  • SEUS PTGI HRR

There are some shaderpacks that are also supported, but not listed above, so you can test them by yourself.

This mod only supports some specific versions of Iris or Oculus !!!
