1 Fill Light Responsible for this are HDRI maps. Typically, these are spherical photographs with a wide color range, allowing the reproduction of light from the HDRI map in renders. Besides light, they also mirror reflections, achieving high realism.
2 Directed Lighting HDRI maps do not always provide the necessary contrast, hence the addition of a tool-sun. In the latest versions of Corona, the default sun has a good built-in HDRI, which for midday lighting allows the use of standard lighting.
3 Local Light Sources These include various lanterns, interior lighting, etc. There are many ways to recreate a light source. It is important to remember that each light is a load on the scene, and an excess can lead to scene crashes.
