I am in the process of working on my first UE project. Its going slow but I am learning a lot and love the program. Here is my latest build. I am using a skylight with a hdri map along with lightmass portals in the window wall.
I am getting weird light leaks in areas as you can see by the enclosed images. I also enclosed my light mass settings as well. I have not tweaked my BaseLightmass.ini file.
What should I be checking to get ride of those leaks?
