Hi there,

I baked my stationary lights including some point lights and a directional light in a level. My FPS now increased but LightScattering increased in time in GPU Profiler. Can you explain to me what is light scattering and why it’s so huge here?

Thank you

I found it. It’s related to volumetric fog and scattering of light in fog.
