Frequently asked questions

How do I turn on UltraLow Shaders after installing it?
Open your Options menu in-game, go to Video Settings, then look for Shader Packs or Graphics options depending on your loader. Select UltraLow Shaders from the list and apply—you should see subtle shadows and colored lighting take effect immediately.
Why do my shadows look too dark or too faint?
Use the shadow intensity adjustment in the shader settings (usually found in Video Settings under Shader Options). Increase it for more dramatic shadows or decrease it if they're washing out your builds.
Does UltraLow Shaders work with Optifine?
UltraLow Shaders is designed to work with Iris and Sodium for best performance on low-end systems. Compatibility with Optifine varies by version—check the mod's official documentation or community forums for your specific setup.
My frame rate dropped after installing the shaders. What do I do?
Try disabling colored lighting effects or reducing shadow intensity in the shader settings, as these are the most performance-intensive features. If that doesn't help, ensure you're using Sodium or similar optimization mods alongside the shaders.
