Light Meter is a visual debugging tool used to simplify lighting adjustment. Open it via the Rendering - Light Meter and you’ll see illuminance distribution for all surfaces in the scene as a color gradient from zero to the maximum level. Recommended lighting levels are provided for quick reference.
We recommend using this tool for lighting adjustment in your scenes. Physically correct lighting is a key to photorealistic graphics and is especially important for computer vision learning in virtual environments.
