渲染管线的兼容性
使用URP制作的项目与高清渲染管道(HDRP)或内置的渲染管道不兼容。在开始开发之前，必须决定在项目中使用哪个渲染管道。有关选择渲染管道的信息，请参见Unity手册中的渲染管道部分。
Unity播放器系统要求
这个包没有添加任何额外的特定于平台的要求。一般的系统要求适用于Unity玩家。有关Unity系统需求的更多信息，请参见Unity的系统需求。
功能对比表
这个表格提供了通用渲染管道(URP)支持的当前特性的概述，并与Unity内置渲染管道进行了比较。
注意:如果一个特性被标记为 In research（研究中），URP团队仍然在研究如何以及何时实现该特性。如果一个特性被标记为Not supported（不支持），那是因为Unity不打算在任何版本中支持它。
