Cubemaps (Source 2)

Source Engine

Source 2

This is a draft page. It is a work in progress open to editing by anyone.
Remember to check for any notes left by the tagger at this article's talk page.

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_(Source_2) ent_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.
