I'm currently doing an archviz environment that has both an outdoor and indoor component. I added a stationary skylight actor to improve the indirect lighting for the outdoor side, but it introduces really strange artifacts on almost all my interior walls. I've increased the skylight intensity to 10 to exaggerate the effect so you can see here
I have a lightmass importance volume in the level already, and these walls are very simple square plane meshes being separated from every other wall. I'm also using UE4.5 and the automatic UV import (which works great btw thanks for including this feature). Increasing lightmap resolution doesn't really help.
Are there any solutions to this?

Hey JLO -
Turn off Cast Shadows from your Skylight and the artifacts should disappear. The Skylight should still affect world and provide an overall illumination increase in your level. If you want to have shadows in the individual rooms you should be able to add point lights based on the positioning of interior lights, your directional lighting shadows should still work as well.
