I used both Unreal and Unity at FAANG. VR and AR apps are obvious use cases but you find the engines in all kind of random places. Especially common in ML research groups for scene and environment understanding

It is the main engine that Microsoft pushes for HoloLens, for example.

It is also what Google sponsors for Stadia and Android games, instead of doing their own SceneKit.

Unreal, not Unity. Making a game.

my guess: oculus. https://developer.oculus.com/documentation/unity/?locale=en_...
