Very fast shader which draws millions of point sprite lights.

SpriteLights consists of custom shaders and an API which can be used to render millions of Physically Based lights in a single batch. They are not regular Unity lights, as it doesn’t render light hitting a surface. Instead, it renders the light source itself.

The light changes brightness depending on the viewing angle, attenuates with distance, and is visible even if it is smaller than one pixel. This combination gives the lights a realistic appearance when viewed from a distance.

It is perfect for Flight Simulators as it contains some aviation specific lights such as walking strobes ,PAPI lights, and runway approach lights. Other use cases are: star fields, point clouds, and city lights.
