Hello, everyone, I made a UE4 scene, but in the process, I found that the lights of the scene will be inexplicable. Under the window editing interface, I rotate the camera angle with the right key, and the scene’s lights will change seriously.
Then, I suspect the fixed lighting problem in my scene, but I checked that the fixed light source overlapped, and no more than 4 lights were found. Then I also found that when I checked the alt+7 mode, I found that the Light Complexity would change with the change of light. Screenshots of the following window effects and screenshots of Light Complexity changes。
If the lighting brightness changes depending on the camera angle, it likely means your auto exposure settings are responsible for this.
Check your post process volume and search for min and max brightness (should be under auto exposure). Set both of these values to 1 (to effectively turn auto exposure off) and see if the problem persists. Keep in mind that by turning off the auto exposure, you may have to readjust your lighting. There should also be an option in the editor to turn it off (which wont affect the game itself) but since my engine is currently compiling I cannot doublecheck that.
