Shaders - Leiriad/-Neoforge-1.20.1-Inventorium GitHub Wiki

Even if Inventorium is Forge/Neoforge powered, I integrated Embeddium to replace Optifine (mainly for performance reasons), to which I added Oculus, its shader mod. So to use shaders, you only need to download them and to put them in the "shaderpacks" folder under "Folder".

You would need to deactivate the Dramatic Sky resource pack, as its features will be overridden by default. You can choose to keep it too: most shaders allow you to use others skies in their parameters.

COMPATIBILITY WARNINGS

This modpack uses Distant Horizons to simulate chunks in the distance. This mod is not compatible with all shaders so I invite you to check this compatibility list before downloading a shader.

Distant Horizon Compatible Shaders

If, as I suggest on the gameplay page of this wiki, you chose to switch the Physics Mod simple version to use the Physics Mod Pro, your choice of shaders is restrained too, for you'll need one that supports ocean physics.

Here is the list available on Physics Mod creator's Patreon:

Physics Mod Pro Compatible Shaders

I personnaly use Complementary Unbound.
