LAN Shaders FAQ

10 questions players actually ask, answered.

How do I enable LAN Shaders after installing it?
Launch Minecraft, go to Options > Video Settings > Shaders, then select LAN Shaders from the list and apply. You'll see the lighting changes take effect immediately in your world.
Will LAN Shaders work with my texture pack?
Yes, LAN Shaders is designed to work with any texture pack since it only adjusts lighting and doesn't replace textures. Your chosen texture pack will display normally with the shader's subtle illumination effects applied on top.
Why is my game lagging with LAN Shaders on?
Try lowering your render distance or disabling other visual mods running alongside LAN Shaders. If you're on a low-end computer, check the optimization guide—you may need to reduce chunk updates or disable other resource-heavy features in your video settings.
Can I make the lighting brighter or darker?
Open the shader options menu (usually accessible from the Shaders screen) to adjust brightness and contrast settings to your preference. Changes apply in real-time, so you can preview adjustments before saving.
Does LAN Shaders add new blocks or items?
No, LAN Shaders is purely a visual mod that only affects lighting—it doesn't add any new content, blocks, or items to your world.
Why do I see flickering or weird shadows?
This usually happens when shader settings conflict with your graphics card or other mods. Try disabling shadow mapping in the shader options, or check that your graphics drivers are up to date.
Is LAN Shaders compatible with Optifine?
LAN Shaders requires a shader-compatible mod loader (like Fabric with Iris) rather than Optifine, as they use different shader systems. Using both together may cause conflicts.
Will LAN Shaders affect my FPS in caves or indoors?
LAN Shaders has minimal performance impact even indoors since it uses simple lighting calculations. You should see only a small FPS drop compared to vanilla, especially on the recommended settings for your hardware.
How do I turn off LAN Shaders without uninstalling it?
Go to Options > Video Settings > Shaders and select 'None' to disable shaders. The mod stays installed but won't affect your game until you re-enable it.
Does LAN Shaders change water or lava appearance?
LAN Shaders preserves standard water and lava textures without adding reflections or distortions. It only adjusts how light interacts with these blocks to maintain the vanilla look.
