Pokémon Go developer Niantic is making its augmented reality tech more like actual reality, as seen in a new demo that lets virtual versions of Pokémon like Pikachu and Eevee hide behind real-world objects.

A brief video of Niantic’s demo, dubbed Codename: Niantic Occlusion, shows AR characters running behind people who are walking as well as static objects in a real-world environment — not just slapped over top of a camera feed, the presentation Pokémon Go players are used to.
