Lights are used to light your scene, and create special effects. They behave exactly like theatrical lights except that you can put them anywhere, even inside objects.
There are three Light types in the Light settings: Point lights, Infinite lights, and Spot lights. There is also a Global light, which provides default lighting, should your scene have no lights added. See Global lights.
These lights can be translated, rotated, scaled, colored, and animated.
Settings are used for all light types unless otherwise noted. When properties cannot be used for the selected light type, their sliders are disabled.
