My frame rate dropped after enabling ULS Shaders. How do I fix it?
Check the shader settings menu for lighting intensity and shadow distance options, and reduce them to lower values. You can also lower your render distance or disable advanced lighting features to improve performance.
Can I use ULS Shaders without Iris?

Why do caves look too dark or too bright with this shader?

Does ULS Shaders change how water looks?
Yes, ULS Shaders enhances underwater lighting and reflections to make water more visually interesting. You can fine-tune water appearance through the shader settings if needed.
Will ULS Shaders cause lag in multiplayer servers?
Shaders run client-side only, so they won't affect server performance or other players. Your personal frame rate depends on your hardware, but ULS is designed to minimize lag on modest systems.
Can I adjust the sky and cloud colors?

What should I do if ULS Shaders won't load or crashes my game?
Verify that Iris is installed and compatible with your Minecraft version, then try removing and reinstalling the shader pack. If crashes persist, check that your graphics drivers are up to date.
Does ULS Shaders work with other mods?
ULS Shaders is compatible with most mods since it only affects rendering. However, mods that heavily modify lighting or world generation may cause visual conflicts—test in-game to confirm compatibility.
