Does Sky Light generates light?

I’m curious how the Sky Light works in Unreal. According to docs: “The Sky Light captures the distant parts of your level […] and applies that to the scene as a light”. Does it mean I need to place some other source of light in my level for the Sky Light to generate reflections? Can the Sky Light produce light on its own?

Yes you are correct .All lights have a unique use and functionality if you have used them …Here is a video that shows their functionality and usage .link to youtube video ue 4 skylights
