Color correction (entity)

Template:Base point It loads a color correction lookup table (.raw) and controls its strength. Correction is applied in a sphere surrounding the entity, with a configurable amount of falloff. By default the effect fades in gradually and only reaches peak intensity at the entity's exact location.

In Left 4 Dead and Left 4 Dead 2, this entity will behave like color_correction in previous Source-based games if there is at least one fog_volume brush entity textured with the fogvolume material. The flags "Master" and "Simulate client-side" must be checked in the main color_correction entity. There can only be one master color_correction. It is recommended that the other color_correction entities be triggered with fog_volume with an override of the master. The override is done by setting the fog_volume entity property called ColorCorrection Name to a color_correction targetname of your choice.

Bug:In Team Fortress 2, color_correction causes control point HUD icons to display improperly. (example).  [todo tested in ?]

Fix color being too intense

Fix for too much color: 1. create a neutral .raw file (i.e. delete all .raw files, open your map, open the color correction ui and click save without creating filters)

2. create your desired color correction and save it.

3. open both .raw files in Photoshop, paste your .raw over the neutral one, set the layer opacity to 50% for your color correction and then save it as a .raw with the appropriate filename (i.e. the one your map will be looking for)
