Fix the Shader Not Showing or Looking Wrong

If the world doesn't look like the cinematic, Call of Duty-style screenshots, work through these checks.

The shader isn't applying at all

1. Open Settings → Global Resources → My Packs and confirm the shader is under Active, not just installed.

2. Move it to the top of the Active list. Another pack above it, such as a texture pack or another shader, can override its visuals.

3. Deactivate any other shader packs. Two shaders fighting each other usually means neither works properly.

4. Check the world itself. Open the world's Edit → Resource Packs screen and make sure a world-specific pack isn't replacing your global setup.

5. Fully close and reopen the game after changing packs. This forces a clean reload.

It loads, but looks off or runs badly

• Scenes look flat: Test at sunrise, sunset and night. The golden glows, glowing moon, green fog and green-tinted night sky are the easiest effects to recognise. Midday on an overcast day hides most of them.
• Colours seem washed out or too dark: Adjust the vanilla Brightness slider in Video settings. The shader's tone mapping and white balance sit on top of it.
• Lag or stutter: Lower render distance first, then close background apps. Shaders that use features like PBR and tone mapping ask more of your device than vanilla does.
• Overheating on mobile: Play plugged in with good airflow, and lower render distance for long sessions.
