USL Shaders FAQ

Open Options > Video Settings > Shaders, then select USL Shaders from the list and apply. You'll see the lighting changes take effect immediately in your world.

Check your shadow quality and lighting detail settings in the shader options—lowering these will improve performance. Also ensure your render distance isn't set too high, as that affects all shaders equally.

Yes, USL Shaders works with most mods, but mods that heavily alter lighting or add custom blocks may cause visual conflicts. Test your mod combination in a test world first.

Open the shader options menu (usually accessible from Video Settings) to find color, saturation, and brightness sliders that let you customize the look while maintaining performance.

This often happens with shadow distance set too high or on Intel integrated graphics—try lowering shadow quality in the shader settings or reducing shadow distance to fix the issue.

Yes, it's specifically optimized for Intel integrated graphics, but you may need to lower shadow and lighting quality settings to maintain smooth performance depending on your exact GPU model.

Higher lighting quality adds more detailed shadows and smoother light transitions but uses more GPU power; lower settings simplify these effects to keep the game fast on older hardware.

Yes, most shader options allow you to reduce or disable shadows, ambient occlusion, and other effects individually through the shader settings menu to find your performance sweet spot.

Adjust the brightness and contrast sliders in the shader options, or check if your monitor's brightness is set correctly—USL maintains vanilla colors but lighting changes can make this more noticeable.

Shaders generally conflict with other graphics mods like Optifine's built-in shaders; you should only use one shader pack at a time, but USL works fine with performance mods like Sodium.
