Description

Iterates over ALL stationary light components in the target world and assigns their preview shadowmap channel, and updates light icons accordingly. Also handles assignment after a lighting build, so that the same algorithm is used for previewing and static lighting.

This function is supposed to be called only when

• loading a map (UEditorEngine::Map_Load)
• a light's lighting cache gets invalidated (ULightComponent::InvalidateLightingCacheDetailed)
• finishing a lighting build If you're adding more call sites to this function, make sure not to break GPULightmass as it is based on the above assumption
