Global ents.vmf (Portal 2)

Contains the basic global entities needed to set up a map, with various triggers to adjust the tonemapping and fog. It is typically found in: C:\Program Files\Steam\steamapps\common\portal 2\sdk_content\maps\instances\

See Working with instances for information on how to activate the environment preset triggers.

HDR & Fog Presets

Showcase of all environment fog presets

These presets are controlled by relays. The func_instance_io_proxy has an output for each relay. Each relay has its own corresponding env_fog_controller, and also sends outputs to "@tonemapper".

There are color_correction and postprocess_controller entities corresponding to each preset, though these do not appear to be used by the relays.

Each color_correction is named after its corresponding preset, with the suffix "_colourcorrection". (e.g. "environment_testchamber_colourcorrection")

Each postprocess_controller is named after its corresponding preset, with the suffix "_postfx". (e.g. "environment_testchamber_postfx")
