Hey Eric,
I have been meaning to reply to this thread for awhile. The issue is still present for me. Our game is using a fully dynamic light setup. We want to use a movable skylight for many reasons. Here is a video clearly showing the issue:
Also, I have noticed that the buffer visualization for Material Ambient Occlusion doesn’t show anything but white. This has been here since UE4’s release I believe. Is this a bug or intentional?
