Ok, I’ve got it.
I’ve completed RE3:Nemesis for a 2 times. But I’ve completed RE4 for a 4 times ))
For camera movement you should learn something about splines, So you need to setup many splines in your level to make camera movement along them.
For a pre-rendered backgrounds - start from SceneCaptureCube actor. It will render your 3D scene into cubemap. You can save it to static texture by pressing RMB -> create static texture or something like that.
Then you need some Sphere mesh in your level. You will map that static cubemap on it by specific material.
