Half-Life: Alyx.
Entity description
The env_spherical_vignette is a point entity which acts similar to gradient fog but can be placed in set locations rather than being attached to the player. The Fog itself is cast radially from the entity origin and can fade seamlessly over mesh geometry both static and dynamic.
