VolumetricFogRenderer has it's own lightbinner outside of lightbinner pool, does lightbinning to fetch fog lights for the fog context only, fixes fog light settings not doing anything, deprecate LAYERFLAGS_NEEDS_FOG_CONTRIBUTING_LIGHTS since we don't need special code for that anymore Share dynamic shadow atlas if we have more than one lightbinner per view ( for example, fog ), fix light fog strength Put fog mode in it's own category and add nice icons to them https://files.facepunch.com/sam/1b0611b1/zwd8qAJFu7.png Some lightbinner cleanup, allow it to be used directly without the complex system that scenesystem wants, remove bRenderFogClipmaps for LightBinner::InitFromParent and disable fog shadows Make sure this is properly inlined to never trash cache Make fog lights buffer persistent with the volumetric fog's lifetime
