| description | Create and configure URP Decal Projectors plus DecalRendererFeature setup — project decals onto surfaces and wire the renderer feature. Use when adding decals in URP, configuring a Decal Projector, or enabling the Decal Renderer Feature, even if the user just says "贴花" or "decal". 创建与配置 URP Decal Projector 并设置 DecalRendererFeature(将贴花投射到表面、接入渲染器特性);当用户要在 URP 中添加贴花、配置 Decal Projector 或启用 Decal Renderer Feature 时使用。 |
Decal Skills
URP Decal Projector creation and configuration (URP only; HDRP decal APIs are not covered here).
Operating Mode
- Query skills (
decal_get_info, decal_find_all) are SkillMode.SemiAuto — they run in all three modes without grant.
- Mutating skills (
decal_create, decal_set_properties, decal_set_properties_batch, decal_ensure_renderer_feature) are SkillMode.FullAuto — under Approval they need user grant (grant triggers one server-side execute returning the result); under Auto / Bypass they execute directly.
decal_delete carries SkillOperation.Delete and is auto-forbidden in Approval / Auto modes (NeverInSemi). Only Bypass or the user-managed Allowlist can run it.
URP Package Stub
This module is compiled against com.unity.render-pipelines.universal (URP). When URP is not installed, every skill returns a stub { error: "Universal Render Pipeline package … is not installed." } (RenderPipelineSkillsCommon.NoURP()). The stub is a diagnostic payload, not a permission denial — it does not require grant and is not treated as NeverInSemi.
Guardrails
Routing:
- For renderer feature management in general:
urp
- For DecalProjector scene operations: this module
Runtime-first rules:
- Call
decal_ensure_renderer_feature before assuming the current URP renderer is decal-ready
- Use
decal_get_info / decal_find_all to discover real projector state before editing
decal_set_properties_batch expects items to be a JSON array string- This module targets the URP Decal workflow first; do not assume HDRP decal APIs are covered here
