在屏幕上显示图像之前,__后期处理__将全屏滤镜和效果应用于摄像机的图像缓冲区。此技术可以通过很短的设置时间大幅改善应用程序的视觉效果。后期处理效果可用于模拟物理摄像机和胶片属性。
本手册的这一部分概述了 Unity 中可用的后期处理效果。有关如何使用这些后期处理效果的具体信息,请单击每个页面上的链接。
下面的图像展示了应用和未应用后期处理的场景。
可用的后期处理效果和这些效果的应用方式取决于所使用的渲染管线。一个渲染管线的后期处理解决方案与其他渲染管线不兼容。
渲染管线 | 后期处理支持 |
---|---|
内置渲染管线 | 默认情况下,内置渲染管线不包含后期处理解决方案。要在内置渲染管线中使用后期处理效果,请下载后期处理 (Post-Processing) 版本 2 包。有关在内置渲染管线中使用后期处理效果的信息,请参阅后期处理 (Post-Processing) 版本 2 的文档。 |
通用渲染管线 (URP) | URP 包括自身的后期处理解决方案(由 Unity 在使用 URP 模板创建项目时安装)。有关在 URP 中使用后期处理效果的信息,请参阅 URP 后期处理文档。 |
高清渲染管线 (HDRP) | HDRP 包括自身的后期处理解决方案(由 Unity 在使用 HDRP 模板创建项目时安装)。有关在 HDRP 中使用后期处理效果的信息,请参阅 HDRP 后期处理文档。 |
注意:后期处理栈 (Post processing stack) 版本 1 现已弃用,不应再使用。
