UrhoX 引擎内置材质库与 PBR 材质系统完整指南，包含 35+ 预制材质（地面、墙面、金属、木材、石材、玻璃等）和程序化材质配置。Use when users need to (1) 选择或添加材质 material 纹理 贴图, (2) 展示/演示/demo 引擎内置材质或预制材质库, (3) 搭建 3D 场景（室内/室外/工业/自然）, (4) 创建 PBR 视觉效果（金属 metal、玻璃 glass、发光 emissive、水面 water）, (5) 使用基础几何体 Box/Sphere/Cylinder 搭建环境, or any other material-related tasks.
Repository-grounded threat modeling that enumerates trust boundaries, assets, attacker capabilities, abuse paths, and mitigations, and writes a concise Markdown threat model. Trigger only when the user explicitly asks to threat model a codebase or path, enumerate threats/abuse paths, or perform AppSec threat modeling. Do not trigger for general architecture summaries, code review, or non-security design work.
