An omni light is a "point light source" that can illuminate evenly in all directions, with an adjustable range that can cast shadows on objects. An omni light is the most widely used light source in renderings, known as a standard omni light Used to illuminate the entire scene, there is no specific range. Multiple floodlights can be used to coordinate in the scene to create better effects. It should be noted that floodlights should not be too many, otherwise the effect picture will appear dull and rigid. Therefore, in the production of ordinary effect pictures, it is necessary to pay more attention to the impact of lighting parameters and layout on the overall scene lighting, accumulate more experience, and master the matching techniques of lighting Qiao.
