Easy Light is an addon that simplifies the process of generating lighting setups in Blender. It allows users to quickly add different light types, apply volume effects, and use randomization to explore alternative looks. Users can restrict the randomization to specific attributes, such as colors or individual light properties, or choose to randomize everything simultaneously. The addon includes a Control Cube to help fine-tune the results and features a system for saving preferred lighting configurations to be reused or mixed later.
