Error: unreal engine skylight not working

Solution

Detailed Solution to Fix Unreal Engine Skylight Issues

1. Check Skylight Component Settings

• Ensure the Skylight component is properly placed in your scene.
• Adjust the Skylight's properties:
• Intensity: Increase the intensity if the skylight is too dim.
• Mobility: Set to "Movable" for dynamic scenes, "Stationary" for static scenes.
• Indirect Lighting Intensity: Increase if the indirect lighting from the skylight is too weak.
• Cast Shadow: Enable if you want the skylight to cast shadows.

2. Rebuild Lighting

• If you have a static or stationary skylight, you must rebuild the lighting in your scene.
• Go to the "Build" menu and select "Build Lighting Only" to bake the lighting.
• Wait for the lighting build to complete before testing the skylight.

3. Optimize World Settings

• In the World Settings, ensure the "Ambient Intensity" is set high enough to complement the skylight.
• Adjust other environment settings like "Sky Light Intensity" and "Directional Light Intensity" to balance the lighting.

4. Check for Post-Processing Effects

• Inspect any post-processing volumes in your scene, as they can significantly impact the appearance of the skylight.
• Adjust post-processing settings like "Tonemapping" and "Color Grading" to see if that resolves the issue.

5. Update Unreal Engine

• If you're using an older version of Unreal Engine, try updating to the latest stable release.
• Newer versions may have fixes for known skylight-related bugs.

6. Use Lightmass Importance Volume

• Place a Lightmass Importance Volume in your scene to optimize lighting quality in critical areas.
• This can help improve the effectiveness of the skylight.

7. Inspect Level Blueprint and Scripts

• Check if any custom scripts or blueprint logic are interfering with the skylight's behavior.
• Disable or modify any relevant scripts to isolate the issue.

If none of these steps resolve the problem, consider seeking help from the Unreal Engine community forums or support channels, providing detailed information about your project and the specific issues you're facing.
