Luminance Mod FAQ

No, Luminance is a library mod that works in the background. You only need it installed if another mod requires it as a dependency. By itself, it won't change your game.

Luminance doesn't improve shaders directly, but it enables shader developers to access more in-game information through Dynamic Shader Uniforms, which allows them to create more advanced visual effects. The improvement depends on whether your shader pack is designed to use these features.

You can use Luminance's built-in detection to verify if Iris Shaders are active in your game. Check the guide 'Check if Iris Shaders are Active in Your Game' for the specific method.

Start by checking the 'Troubleshoot Shader Compatibility Issues' guide to diagnose the problem. Common issues include shader packs not being compatible with your version or conflicting mods, but Luminance should actually improve compatibility rather than break it.

Dynamic Shader Uniforms are variables that pass real-time game information to shaders, like player position or weather conditions. Shaders designed to use them can create more responsive and detailed visual effects. See 'Understand Dynamic Shader Uniforms and What They Do' for details.

Yes, Luminance allows you to configure and add custom Dynamic Shader Uniforms beyond the default ones it provides. This is mainly useful for mod developers creating custom shader effects.

Luminance improves compatibility and fixes shader namespace issues, but not all shader packs are designed to take advantage of its features. Older or simpler shader packs will work fine, but won't benefit from Dynamic Shader Uniforms.

Only if you want to use the shaders that Luminance includes from previous Minecraft versions. If you're just using Luminance as a library dependency or with other shader packs, these aren't required.

Luminance is a lightweight library mod and shouldn't noticeably impact performance on its own. Any performance changes would come from the shader packs or mods using Luminance's features.

Minecraft doesn't natively organize shaders and shader textures with namespaces, which can cause conflicts. Luminance fixes this organizational issue so shaders work more reliably without naming conflicts.
