thank you so much for your full description yes i have solved my problem and i’m satisfied of the result but i’m sure it can become even more nicer with all what you mention too my goal to create motion graphics inside UE4 because it save so much time for rendering not like render in 3d software like 3ds max or cinema 4d so i start use it for that and i know it can do more things over that it’s game engine 
so i just use it in my way
about post processes i only care about simple stuff like AO - DOF - thoes kind effect look more for colors and look i deal with software more professional in that
so i need to know where i can find Screen Percentage to rise it up and what else i can change for quality and how i can rise up AO more than 1.0
please try to show simple in image to be more easy to get
thanks again and i will come again
