Hi there, I ran into this problem recently, designing an island bungalow... never had this kind of problem before... When I move my mouse, at some point suddenly my image turns negative black and white, when I move my mouse just a millimeter, it disappears. I deleted all light sources in the house, but that doesn't change anything. I think it has something to do with the sunlight and maybe reflections on the glass windows (that I use a lot) I chose sundown, so light of the sun is very low. Here's some screenshots with normal and bad angles... Anybody has an idea how to remedy this ? Thanks in advance ! Layla
