Limitation

1. The <ColorCurves>component cannot be animated. This is because the component's field type is a type that cannot be animated. If you want to animate this component, it is recommended to blend by adjusting the weights of two PostProcessing Volumes with different values.
2. PostProcessing Controller, as its name suggests, only works for PostProcessing. There are several Volume Components in HDRP besides PostProcessing, but this script only deals with PostProcessing. As an exception, you can currently use the Exposure feature, and I plan to gradually increase the number of features available in the future.
3. Cannot animate Quality dropdown. Because that field works as a preset for other fields, it's almost like setting “Quality == Custom” in almost all cases.
4. Some fields are not displayed in red even though Animation is being recorded. But it's a problem in the process of drawing the GUI, it actually works fine. Check the bound properties in the Animation Window to check if the field is being recorded properly.

Other Details

1. The example scene was tested on 2020LTS. If the scene isn't working properly, make sure the camera's PostProcessing flag is checked and there are no issues with the Render Pipeline Settings.
2. PostProcessController was built with Unity's animation features in mind. It has not been tested for other uses and cannot be guaranteed. However, if you have any great ideas for other uses, please send us an email!
3. Updates to Unity's Render Pipeline are very frequent and unpredictable. If you find an incompatible version, please let us know!
