version: "1.0.2" name: unity-postprocess description: Configure modern SRP post-processing on URP/HDRP VolumeProfiles — add and tune effects like bloom, tonemapping, and color grading. Use when setting up post-processing, adding effects to a VolumeProfile, or tuning the look of a URP/HDRP scene, even if the user just says "后处理" or "加个泛光". 在 URP/HDRP VolumeProfile 上配置现代 SRP 后处理(添加与调校泛光、色调映射、调色等效果);当用户要搭建后处理、向 VolumeProfile 添加效果、或调整 URP/HDRP 场景观感时使用。

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

Runtime-first rules:

• Always call postprocess_list_effects before assuming an effect exists on the active pipeline
• Use postprocess_get_effect or volume_get_component to inspect real parameter names before setting generic parameters
• Prefer the dedicated high-frequency skills (postprocess_set_bloom, postprocess_set_depth_of_field, etc.) over guessing generic parameter names
• Treat URP and HDRP parameter surfaces as similar-but-not-identical; do not reuse names blindly across pipelines
