Weird artifacts

[Alexarg]

Im having a weird effect on walls (I hope you can see it, with video compression is not very clear)

Is like weird shadows on the walls and roof.

Is this some kind of artifacts? I suspect my Lightmass configuration maybe..

Thanks!

You can try adjusting the Quality settings of lightmass and the smoothing settings, it might increase the lighting build times though. If you haven't already, build using Production quality, and make sure you have a lightmass importance volume setup.

OK i will try (i tested most of the things mentioned), However, I not sure if in the video is appreciated the "effect" of shadows that move through the wall and roof. Due to the compression of the video is not very clear, but the effect is most noticeable than in the video.
I can upload another video more detailed if the strange effect is not appreciated.

It looks like DFAO(Distance Field Ambient Occlusion.) Turn the Skylight in your level into Static or disable DFAO in project settings if you dont want that feature at all.

Nice eye, Jacky. that does look like DFAO. I didn't catch that the first time I watched it earlier today.

@Alexarg: If you're using DFAO you can adjust these in the skylight settings.

Yes!, the Skylight config was the problem, for some reason i had the intensity way too hight. Happy again
