Frequently asked questions

How do I turn on global illumination after installing the shader?
Open your shader settings menu (usually accessed through the pause menu or a keybind), then locate the Global Illumination toggle and enable it. You may need to adjust the intensity slider to see the effect clearly on your current build.
Why do my caves look too bright or washed out?
This is often caused by global illumination bouncing light too aggressively in enclosed spaces. Use the guide 'Make Caves and Underground Spaces Feel Naturally Lit' to dial back the GI intensity or adjust ambient occlusion settings for more realistic shadow depth underground.
Does this shader work with other lighting mods?
R T S Shaders replaces the game's core lighting calculations, so using it alongside other lighting mods can cause conflicts or unpredictable results. It's designed to work standalone with vanilla Minecraft.
My FPS dropped a lot after enabling this. How do I fix it?
Global illumination is computationally expensive; refer to 'Optimize Performance While Keeping Visual Quality' to reduce GI sample count, lower render distance, or disable GI on less important areas. You can also reduce shadow quality or resolution settings.
