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 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.
