Film Green Screen Virtual Set Photorealistic

Hey guys,

I am looking to use a green screen for actors and then place them in a virtual environment created by unreal. I am brand new to UR and wondering if there are any tutorials or courses for film. Compositing, motion tracking, photorealistic, etc. I have no idea what it is called or what to search for. Virtual production? I don’t need real time right away. Basically, I am looking for some course on how to build a photorealistic environment for film, then place actors from a green screen in it from start to final high resolution scene. Any help would be awesome! Thanks
