I change the color of the basic wall in start-up content, but I get this ugly looking cloudy wall.

I build the lighting on production setting and deleted every light source except 1 point light. I also tried changing the roughness but the cloudy wall is still there. Anyone know how do I fix this?

HI!

You need to adjust parameters for calculating quality of light map. Read this guide:

If that is bsp, lower the lightmap resolution. If it is a static mesh, increase it. See if that helps.
