Shortly after entering a level it appears as if the lighting slightly changes color, or becomes slightly brighter.
The image on the left is how it appears in the editor, as well as immediately upon entering the level.
The image on the right is how it appears after the lighting / hue change which occurs between 2 and 5 seconds after level load.
What’s in the level:
The level is almost empty, with only a few static meshes, a default camera, and a few lights.
This occurs even with only a single point light.
The material is very simple with a textured base color, 0 Metallic, 0.2 Specular, 0.8 Roughness
The problem is NOT eye adaptation, as that is disabled in my project. The change is an instantaneous switch from the lighting on the left to that right.
