ATG is a grass rendering solution which was built to replace the detail rendering system of Unity’s terrain engine in order to get rid of all spikes on the CPU — caused by new grass patches coming into sight when your camera is moving.
Next to this initial purpose ATG offers significant improvements regarding lighting and wind animation.
Since version 1.2 ATG supports the Universal Rendering Pipeline which also supports touch bending or grass displacement.ATG是一个草地渲染解决方案，它的建立是为了取代Unity地形引擎的细节渲染系统，以摆脱CPU上的所有峰值--当你的相机移动时，新的草块出现在视线中
Since version 1.07 ATG supports third party solutions such as Vegetation Studio and lets you use ATG's advanced lighting and bending features within these.
