An example of specular reflections on some models (exaggerated through
r_showenvcubemap).A cubemap is a texture that represents a three-dimensional rendering of an area. 
Source 2 has env_cubemap and/or env_cubemap_box entities as sampling points to generate these textures, which are then integrated into the map file. Cubemaps in Source 2 are also parallax corrected if env_cubemap_box is used.
Todo: Document about env_cubemap_fog.
Preview
New in Source 2 Hammer. You can preview cubemaps by going to "Preview Baked Lighting" menu > Bake All Cubemaps. You can also use "Bake Selected Cubemaps" to preview the selected cubemaps.
