Fix Lag or Visual Problems with Vibrant Realism PBR Shader

Realistic shadows, reflections and ambient lighting put more load on your device than vanilla visuals. If the game stutters or looks wrong, work through these steps.

Improving performance

1. Open Settings → Video.

2. Lower Render Distance first. This usually gives the biggest frame-rate gain.

3. Turn off optional extras you can live without, such as Beautiful Skies.

4. Close other apps running in the background, especially on mobile.

5. Reload your world and test in a demanding spot, such as a jungle or beside a large body of water.

If it's still too heavy, keep the shader for screenshots and building sessions. Switch it off in Global Resources for long survival play.

Fixing visual glitches

• No shader effects at all: Check that the pack is in the Active list, not just installed in My Packs.
• Effects only in some worlds: You may have activated it per world instead of globally, or vice versa. Check both places.
• Strange colours or broken lighting: Deactivate every other pack except the shader and your PBR textures. Add the others back one at a time to find the conflict.
• Textures look flat: Try swapping the order of the shader and your PBR texture pack in the Active list. Then reload the world.

After any change, fully exit to the main menu and re-enter the world so the resources reload cleanly.
