PostProcess Skills

Modern URP / HDRP post-processing skills built on top of the SRP Volume framework. For Volume container / profile CRUD (volume_profile_create, volume_create, etc.), use the volume module.

Operating Mode

• Query skills (postprocess_list_effects, postprocess_get_effect) are SkillMode.SemiAuto — they run in all three modes without grant.
• Mutating skills (postprocess_add_effect, postprocess_set_parameter, postprocess_set_bloom, postprocess_set_depth_of_field, postprocess_set_tonemapping, postprocess_set_vignette, postprocess_set_color_adjustments) are SkillMode.FullAuto — under Approval they need user grant (grant triggers one server-side execute returning the result); under Auto / Bypass they execute directly.
• postprocess_remove_effect carries SkillOperation.Delete and is auto-forbidden in Approval / Auto modes (NeverInSemi). Only Bypass or the user-managed Allowlist can run it.

SRP Package Stub

This module is compiled against com.unity.render-pipelines.core (SRP_CORE). When neither URP nor HDRP is installed (no SRP Core), every skill returns a stub { error: "Scriptable Render Pipeline Core package … is not installed." } (RenderPipelineSkillsCommon.NoSRP()). The stub is a diagnostic payload, not a permission denial — it does not require grant and is not treated as NeverInSemi.

Guardrails

DO NOT:

• Use this module for PPv2 / com.unity.postprocessing
• Use this module for general Volume container/profile management; use volume
