PostProcessingVolume not working

Hello !

I’m using UE4.9, for a mobile game : the preset selected is Scalable 2D/3D, and mobile target.
When I place a PostProcessingVolume in the editor, and modify values on it, it doesn’t change anything.
My PostProcessingVolume is activated, and unbound, so it should work.

Thanks !

Answered it myself, In Project Options → Target Hardware, when choosing Maximum Quality, PostProcessVolumes are allowed.
