I dont want to use UE4 rendering and graphics technology, I would like to create my own such as custom render and custom shaders , AA and Bloom, lighting,Vsync that type of things and then import those in unreal engine 4?is this thing possible using gameworks?
You cannot import your renderer into UE or any game engine for that matter, since that would contradict the usage of the engine to begin with. Custom rendering is usually can be achieved via shaders so that is possible. GameWorks is just a collection of libraries that you could use for your project…yes…
