# 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](Custom-Pass-Injection-Points.md).

## 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 |
|
||
|
|
