I don’t really know what’s causing this or how to fix it. I am using UE4.20, my lights and meshes are static. Tried with different quality light bakes and it still does this. I have one large sphere reflection capture for this room, then several smaller spheres placed around. It looks like my roughness maps flicker in and out in this specific area the most whenever I move around. The rest of my scene seems okay. This is not the first time I’ve seen this. It seems to happen most often when I use static lights and meshes. I’ve included some links to animated gifs below to better visualize what’s happening. What’s going on and how can I fix this?
