Iris/Oculus For Simple Clouds

Java mod listed for Minecraft 1.20–1.21. File opened and checked on 8 Oct 2026; downloads from the MC Java Mods app on Android.

by Gaboouu · on CurseForge

This mod adds full compatibility between SimpleClouds’ shader renderer and Oculus’ shader system, ensuring both work together seamlessly.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

DH IS COMPATIBLE!!! 🎉🎉🎉

THE ONLY SHADER COMPATIBLE IS ATMOSPHERIC SHADERS. IF YOU ASK: IS X SHADER COMPATIBLE YOU WILL BE IGNORED

Comments are for feedback about the mod only. Bug reports or issues posted in the comments will be ignored and deleted. Please join the Discord Server to report issues or get support. If you don’t have Discord yet, you can install it here and quickly to join the server to get help.

This project will introduce a compatibility bridge between Oculus and SimpleClouds shader systems.
Only shaders that I explicitly adapt will function with it. You will not be able to use arbitrary shaders.

❓ Does this work with Project Atmosphere?

Absolutely.

❓ Can you request support for a specific shader?

Possibly. To add compatibility, both conditions must be met:

The shader’s source code must be publicly available.
I must have the legal right to republish the modified version.

This means shaders like SEUS cannot be supported.

❓ Does this modify Oculus’ code?

Yes and no.

The mod applies Mixins to Oculus at runtime to create the compatibility layer, but no Oculus code is bundled or redistributed.
You still need to install Oculus separately for this mod to work.
