Lightmass error??

melviso

I am having this issue in a ue4 scene?
For some reason, these faces look illuminated. Any ideas?


I am using the ue4.18 preview 2 version. Is this a bug?

Anyone? This illumination happens after baking lightmass.
Seems the mesh was corrupt. Deleted it and remodelled it from a new primitive. Worked the way it should in ue4.
