Thank you! I work at VrWorks so I can share some of the details about those mirrors. They are possible in UE4, you just have set up some stuff. You have to use reflection captures in your scene, a big one in the center of the room and smaller ones in the corners or in front of highly reflective surfaces (like mirrors). Sphere captures are advised, because cube captures are performance hogs. You can also improve SSR by adjusting some settings in a shader file, here is a great blogpost about that: SSR settings .
