I didn’t use BSP at all. and I couldn’t find my case in these Troubleshooting Guide

you have some dirty shadows.

  • light map resolution

  • indirect lighting quality

  • Indirect Lighting Bounces

  • Indirect Lighting Smoothness

review that page one more time

thanks for answer
Unfortunately these changes make it worse :frowning:

you have not studied that page correctly yet.

what are the light map resolution of different parts of that building?

don’t change those numbers dramatically

you could make it worse by that trouble shooting guide so you can make it better :smiley:
