description: Configure modern SRP post-processing on URP/HDRP

Unity PostProcess Skills

Modern URP and HDRP post-processing on SRP Volume profiles. Parameters come from the schema (`GET /skills/schema?category=PostProcess&wire=v2`); execution and dryRun rules: root [SKILL.md](../../SKILL.md). Volume container and profile management (`volume_profile_create`, `volume_create`, ...) belongs to the [volume](../volume/SKILL.md) module.

When to use

  • Setting up post-processing or tuning the look of a URP or HDRP scene
  • Adding or adjusting an effect override on a VolumeProfile

Rules

  • Call `postprocess_list_effects` before assuming an effect exists on the active pipeline.
  • Inspect real parameter names with `postprocess_get_effect` (or `volume_get_component`) before using the generic `postprocess_set_parameter`; prefer the dedicated `postprocess_set_*` skills.
  • URP and HDRP parameter surfaces are similar but not identical; do not reuse names across pipelines.
  • Query skills are `SemiAuto`. The `postprocess_add_effect`, `postprocess_set_*` and `postprocess_set_parameter` writers are `FullAuto`: under Approval they need a grant.
  • `postprocess_remove_effect` is a Delete operation: refused under Approval and Auto; only Bypass or an allowlist runs it.
  • Without SRP Core installed, every skill returns `{ error: "Scriptable Render Pipeline Core package (com.unity.render-pipelines.core) is not installed..." }`. That is a diagnostic answer, not a permission denial, and needs no grant.

Pitfalls

  • This module is not for PPv2 (`com.unity.postprocessing`).
  • Volume container and profile CRUD belong to the `volume` module, not here.

Questions about postprocess.

Which coding agents can use postprocess?
postprocess installs in Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode and Windsurf with the skills CLI, using each agent's flag shown on this page. Flowy's auto-invocation, which fires a skill when your prompt matches, runs in Claude Code only.
