Hi! This hasn’t been resolved for me and have no clue as to why it is happening. I don’t have a Lightmass Importance Volume or a Post Process Volume in my project, so the points mentioned earlier don’t really appoly to me.
What I’ll do is apply both of these to the entire scene and see if I get any improvements.
Edit: Nope. =( I added the volumes and did all the tweaks suggested, but still get the same results. Even unchecking eye adaptation under Show>Post Processing in the viewport makes no difference to my scene.
