What is Fill Light?
When it comes to 3D visualization, fill light is an important element to consider. This is because fill light can help to create more realistic lighting effects in your 3D scenes.
Fill light is used in photography and cinematography to provide extra illumination for darker areas of the image. In 3D visualization, fill light can be used to add realistic lighting effects to your scene.
For example, if you are rendering a night scene, you may want to add some fill light to brighten up the dark areas. This will help to create a more realistic lighting effect.
