Lighting Bug

I tried to use lightmass character indirect detail volume. And it helps a little bit for sudden brightness changes… But the lighting of my moveable object is still a kind of nonsense…



Sometimes its bright when it should be dark and vice versa. And sometimes its overbright… It has nothing to do with my object because when I use the motioncontroller mesh from the VR-Template its the same. I already disabled postprocessing EyeAdaption…

Any Ideas? thank you!
