I’m sorry, I wasn’t clear. Thank you for giving your time.
Indeed I would like to package the game for pc and mobile, it’s a little game, and I would like to do a professionnal game, so I try to optimize it as best as I can 
So first I used directly the actor Chameleon into the scene, and get it to call his effects.
This is working, but to package only effects I use, I understood in your previous message, that I should use engine’s post process volume. So I added it to the scene to call it, but I don’t understand how to manipulate it with Chamelon’s effects.
I mean, which functions should I call ? There is no “Get Post Process Materials” or “Get Rendering Features”
