Thank you. I have added a PPV as a child to the Pawn’s DefaultSceneRoot but, when dragged onto the blueprint, it is not a valid type of Target for Set Post Process Settings. Equally, Array elements found by Getting All Actors of Class (= Post Process Volume) are not suitable.
Making the PPV a child of the [camera] child of the DefaultSceneRoot (i.e., a grandchild) and Getting the Child Actor of the camera comes up against the same problem.
I must be missing something but at this stage of the UE5 learning-curve, I’m struggling to work out what it is.
Again, thank you for your help.
