Post Processing Editor

Tool Icon

The Post Processing Editor lets you create and edit post processing presets. Post processing can enhance your map by adding effects like exposure, tone mapping, color grading, bloom, and blur. These presets are saved as .vpost resources and control the final look of what players see on screen.

Info​

Post processing applies full-screen (view-space) effects after the scene is rendered, which is where the name comes from — it’s processing done post (after) rendering.

It works by adjusting the already-generated image on screen, and does not use map geometry or re-render the world. Instead, it modifies what’s already been rendered to improve the look.

Post processing is not applied automatically. You must create a .vpost preset in the editor (or use an existing preset) and then apply it in Hammer using a post_processing_volume. Using a master volume, post processing effects can be applied to the whole level.

To edit an already existing .vpost preset you need to decompile it using the Source2 Viewer iconSource2 Viewer and save it in your addon. The default .vpost files are stored in the game/csgo/pak01_dir.vpk/lighting/postprocessing/.

This is explained in detail in the Post Processing Editor Guide.
