Post Processing - s&box Documentation

Official s&box documentation for Post Processing - full-screen visual effects. Post Processing applies effects to the entire rendered image. Creating PostProcesses covers writing custom post-processing shaders. Built-in effects include FilmGrain for film noise, Tonemapping for HDR to LDR conversion, and color grading. PostProcessVolume defines areas where effects are applied with blendable properties. Effects can be stacked and blended between volumes. The system uses the full-screen quad pipeline for efficient GPU processing. Custom post-processing uses BasePostProcess for weighted blending between multiple effects. Render layers control which effects apply to which objects.
