Indium - No Longer Required!
Since Sodium version 0.6.0, the Indium mod is no longer needed! Sodium now has built-in support for the Fabric Rendering API, so you no longer need to install Indium.
Moreover, Indium is incompatible with Sodium version 0.6.0 and above, so don't use it :)
Original Description
Indium is an addon for the rendering optimization mod Sodium that provides support for the Fabric Rendering API. This API is required by many mods that use advanced rendering effects and was not originally directly supported by Sodium. Indium is based on the reference implementation Indigo, which is part of Fabric API with source code available here. (licensed under Apache 2.0)
Frequently Asked Questions
Which mods require Indium?
Any mod that uses the Fabric Rendering API will require Indium when working with Sodium. These include: Campanion, Bits and Chisels, LambdaBetterGrass, Continuity, Packages, and many others. Some of these mods may function without an implementation of the Fabric Rendering API, but will have broken textures and models.
Does Indium affect performance?
Indium's impact on performance should be negligible, however mods that use the Fabric Rendering API themselves can affect performance. Indium will not provide performance benefits compared to using only Sodium.
Is Indium a replacement for Sodium?
No, Indium is an addon for Sodium - you must use both mods together to get Fabric Rendering API support with Sodium's rendering optimizations.
Do I need Indium if I don't use Sodium?
No, Indigo is provided as part of Fabric API as the reference implementation of the Fabric Rendering API. Indigo disables itself when Sodium is installed.
Is Fabric API required?
Yes. To use Sodium with mods that require the Fabric Rendering API, you need both - Fabric API to provide the rendering API and Indium to implement this API.
Will it be merged into Sodium?
Support for the Fabric Rendering API is currently not a priority for the Sodium developers and will not be explored until Sodium reaches a more stable state.
Which versions of Sodium are supported?
For all versions of Indium, Sodium 0.2.0 or newer is required. I support the latest stable versions of Sodium for 1.18 and 1.19. Iris may not always be compatible with the latest release or build of Indium - please contact Iris support channels if you encounter any issues.
