Example of Source 2 skybox. sky_hr_aztec_02_lighting from Counter-Strike 2.

Sky is a shader in Source 2. Unlike Source, skies in Source 2 do not use a 6-sided skybox, but instead a single panoramic image, such as an HDRI map.

Todo:  Counter-Strike 2 supports 6-sided skyboxes, but it uses a single vtex_c instead of one for each face; how are these authored in the Material Editor?
