Hello! Could someone point me the right direction on setting up mixed reality capture with a green screen for my own VR project, like this? I've searched for tutorials and guides but most of what's out there is simply how to set it up for a game that already has it supported, not creating the mixed reality setup in Unity from scratch. I understand the basic concept is using a background and foreground layer, and an alpha mask cutoff layer that is set to the distance of the player's HMD. Then it is composited together with a camera and green screen either in Unity or in external software like OBS. How would I go about setting this up for my own project in Unity? Are there any good guides or tutorials out there?
