pbr-render

使用 / Usage

插件自动注入系统提示教学。模型在合适场景主动调用 pbr_render 工具验证路径，然后输出 pbr3d 围栏： The plugin injects a system-prompt guide automatically. The model calls the pbr_render tool to validate the path, then emits a pbr3d fence:

```pbr3d
{"model":"E:/generated/robot.glb","autoRotate":true,"label":"API 生成的机器人 / API-generated robot"}
```
