Simple Shadows Shaders FAQ

The shaders should be active by default once the mod is installed. If you don't see shadows or colored lighting, check that your graphics settings aren't overriding the shader effects—make sure you're not using a conflicting shader pack or have shader rendering disabled in your video options.

You can adjust shadow darkness and intensity through the mod's configuration settings. Look for shadow-related options in your config files or in-game settings menu to find the right balance for your preference.

No—this mod provides its own shader system and will conflict with other shader packs like Optifine or Iris shaders. You should use one or the other, not both.

Simple Shadows Shaders is designed to run on older hardware with minimal performance impact. If you experience lag, try reducing shadow intensity or disabling colored lighting effects in the config to lighten the load on your GPU.

It's not recommended—Optifine has its own shader system that conflicts with this mod's shaders. You may experience visual glitches or crashes if you use both together.

Adjust the colored lighting intensity in the mod settings to find a balance that feels right. Lower values preserve more of the vanilla aesthetic while still adding warmth and color to your world.

Some transparent or non-solid blocks (like leaves, glass, or water) may not cast or receive shadows properly due to how the shader renders them. This is a limitation of how the mod handles these block types.

Yes—most configuration options let you toggle shadows and colored lighting independently, so you can have just the lighting effects if you prefer.

Yes, this is a client-side mod, so it works in multiplayer and on servers without requiring the server to have it installed. Only you will see the shadows and colored lighting.

This can happen if your shadow settings are too high for your hardware or if there's a conflict with another mod affecting rendering. Try lowering shadow intensity or checking for mod conflicts in your setup.
