How to make a postprocessvolume to affect the whole scene but one object ?
I need to make it so when i click on some object the whole scene become darker but the clicked object stays the same .

You could probably have multiple post process volumes and depending on the object you click on you can set the priority of the post process volume.

Post Process Effects:Post Process Effects in Unreal Engine | Unreal Engine Documentation

Priority setting: Defines the order in which multiple volumes are blended together. The volume with the highest priority takes precedence over all other overlapping volumes.

I’m not for sure on this answer but it may help you get in the right direction.
