StarEngine is the technology on which Star Citizen and Squadron 42 are created. The presented trailer was shot “in the engine as one continuous frame without loading screens.”
There are many transitions in the trailer: from deep space to the snowy surface of the planet, from city interiors to multi-crew spaceships, from underground mines to floating cloud cities.
Other games, like No Man's Sky, have already made smooth transitions from space to planetary surfaces, but when the camera lingers on the cutscene, it shows that StarEngine has other tricks up its sleeve. There is a high level of detail here, and the final part of the video shows the character with sweat covering his forehead.
When this technological miracle will be released is still unknown.
