# Post-Processing

> Post-processing effects — bloom, depth of field, motion blur, tone mapping, anti-aliasing, and color grading — are the final rendering passes that define a game's visual identity.

**Post-processing** refers to the full-screen rendering passes applied after the main scene has been drawn — the visual effects that transform a raw rendered image into the final stylized, polished output the player sees. Post-processing is where a game's visual identity is largely defined: two games with identical geometry and [lighting](https://metavert.io/lighting) can look completely different based on their post-processing stack.

The standard post-processing toolkit includes **tone mapping** (compressing HDR rendered values into displayable range), **color grading** (applying cinematic color transforms via lookup tables), **bloom** (bright areas bleeding light into surroundings), **depth of field** (simulating camera focus with bokeh blur), **motion blur** (directional blur based on camera or object velocity), **ambient occlusion** (darkening creases and contact points — SSAO, GTAO, HBAO), **screen-space reflections** (SSR — reflections derived from what's already on screen), and **anti-aliasing** (smoothing jagged edges via FXAA, TAA, SMAA, or DLAA).

AI is transforming post-processing. NVIDIA's DLSS, AMD's FSR, and Intel's XeSS use neural networks to upscale lower-resolution renders to higher resolution with quality that often exceeds native rendering — effectively replacing traditional spatial anti-aliasing with AI super-resolution. Frame generation (DLSS 3) synthesizes entirely new frames between rendered ones, boosting perceived smoothness. These AI post-processing techniques fundamentally change the performance equation: developers can render at lower internal resolutions and let AI reconstruct the final image.

The artistic dimension is significant. Post-processing is where technical artists and art directors exert the most direct control over visual mood. A horror game's desaturated, high-contrast, vignette-heavy post stack creates atmosphere as effectively as any environmental art. The warm bloom and lens flares of a nostalgic adventure game, the crisp high-saturation style of a cel-shaded title, the film-grain and chromatic aberration of a cinematic experience — all are post-processing decisions. Combined with [VFX](https://metavert.io/vfx) and [shader](https://metavert.io/shaders) work, post-processing completes the visual pipeline from geometry to final pixel.
