插件介绍：
Citigen插件可以在Blender中轻松创建城市环境，无需HDRIs，也不需要为简单的无人机拍摄（如POI或Course Lock）设置摄影机动画。可以根据自己的需求创建配备街道、交通灯、树木等元素的城市环境。Citigen附带的默认城市道具在10到15英尺的距离看起来像真实的物体，足够用于类似无人机拍摄的场景。
Citigen is a Blender add-on. No need for HDRIs, no need for rigging animation cameras for simple drone shots like POI or Course Lock!
With a few clicks, you can create a limitless variety of city environments equipped with streets, traffic lights, trees, and etc–as huge as your RAMs, CPUs, and GPUs allow. The default city props that ship with Citigen will look like a real thing from 10 to 15 feet a way, good enough for drone-shot-like scenarios, but you can add your own detailed building models to the Citigen library for close-up shots!
