Understand execution order
The following diagram shows the order in which the High Definition Render Pipeline (HDRP) executes render passes.
For more information about injection points, refer to injection points.
Post-processing effect execution order
The post-processing system in HDRP applies post-processing effects in a specific order. The system also combines some effects into the same compute shader stack to minimize the number of passes.
Execution order and effect grouping
HDRP executes post processing effects in the following order, from top to bottom.
| Post-processing passes | Compute shader stack | Final post-processing pass |
|---|---|---|
| NaN Killer | ||
| Anti-aliasing (TAA, SMAA) | ||
| Depth of Field | ||
| Motion Blur | ||
| Panini Projection | ||
| Bloom (Pyramid) | ||
| Color Grading (LUT Baking) | ||
| Screen Space Lens Flare (written in bloom texture) | ||
| Data driven lens flare | ||
| Lens Distortion | ||
| Chromatic Aberration | ||
| Bloom (Apply) | ||
| Vignette | ||
| Color Grading (Apply) | ||
| Antialiasing (FXAA) | ||
| Film Grain | ||
| 8-bit Dithering |
