Troubleshoot Visual Glitches or Artifacts

Identify the Problem

Common issues include flickering shadows, banding (visible color bands), strange lighting on certain blocks, or overly bright/dark areas. Note where the glitch appears—indoors, outdoors, near water, or in specific lighting conditions.

Reset to Default Settings

If glitches appeared after adjusting settings, reset the shader to its defaults through the configuration menu. This often resolves conflicts between incompatible setting combinations.

Disable Problematic Features

If glitches persist, try disabling advanced features one at a time:

• Turn off dynamic shadows
• Disable bloom or glow effects
• Reduce shadow quality
• Lower lighting calculation detail

Check Compatibility

Ensure your graphics driver is up to date. Vivid Swift Lighting is optimized for standard hardware, but outdated drivers can cause rendering issues. Also verify that other mods or resource packs aren't conflicting with the shader's lighting calculations.

Verify Installation

Make sure the shader is properly installed in your shader folder and that no files are corrupted. Reinstalling can resolve persistent visual problems.
