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.

• For renderer feature management in general: urp
• For DecalProjector scene operations: this module
