Question Can't see changes on DepthOfField

Greetings.

I am currently working on HDRP Volume profiles and I create Volume and add Depth Of Field to it via script and I can change Depth of Field values from script but can't see the effect on camera. When I change values from script can't see the new values at Depth of Field area until I move my cursor to Depth of Field area at editor. When I move it to area, values are changed but effect is not visible at game. I am not sure if it is a bug or not. Also SetDirty is deprecated, setting isDirty = true and setting DepthOfField.active = true didn't worked for me.

Unity 2021.3.7f1

Thank you.

 

UPDATE

Okay, I figure it out but I am gonna blame Unity devs for it. Documentation about HDRP Volume Overrides basically useless and there is no explanation at functions in Unity.

I realize the changes I made at DepthOfField's near and far ranges start-end can effect my camera in game but not the slider ones under Quality setting. After I dig HDRP codes I see that DepthOfField uses selected Quality Setting even if you change values, that's why new values didn't effect the camera while showed up on editor. You might say that "Why don't you just change quality setting then?". The problem is devs didn't add Custom enum to ScalableSettingLevelParameter.Level as you can see at Image_1.

So you need to set Custom from somewhere else. This is the second weird path to follow. In DepthOfField.cs, every override has same if condition as you can see at Image_2 which checks if override uses Quality setting. But since you can't set Quality to Custom with enum, you had to do some work arounds. To use your custom settings, UsesQualitySettings() should return false so reverse can return true and first if condition can work. But to return UsesQualitySettings false, !quality.levelAndOverride.useOverride should return true and so on which you can see at Image_3. I am sure they did it for some purpose but since there are no proper documentation about it, HDRP must be properly documented from scratch.

TLDR: If you want to use Custom settings at DepthOfField use the below code.

Code (CSharp):

1. dof.quality.levelAndOverride = (1, true);

 

Thank you for your response. This solution only works when you tick quality settings on editor before play. At my position I need to create volumes and DepthOfFields at runtime so can't tick it without;

Code (CSharp):

1. dof.quality.levelAndOverride = (1, true);

 

Thank you so much. Can you inform us about updates?
