Objects are lit up in the scene according to the number, position, direction, and colour of light sources, as well as the rotation and spread of each light source.
You can add up to 64 active light sources to a scene. You can also control each light individually. By default, the light you add to the scene is applied to all surfaces. However, you can also apply a light source to specific surfaces.
Once lights are added to your scene, you can use them to add other effects to enhance the scene, such as cast shadows, lens flares, rays, and blooming effects.
You can also use image-based lighting (IBLs) to light objects in the scene.
