Luminous Engine (ルミナス・エンジン, Ruminasu Engine), originally called Luminous Studio (ルミナス・スタジオ, Ruminasu Sutajio), is a multi-platform game engine developed and used internally by Square Enix and later on by Luminous Productions. The engine was developed for and targeted at eighth-generation hardware and DirectX 11-compatible platforms, such as Xbox One, the PlayStation 4, and versions of Microsoft Windows. It was conceived during the development of Final Fantasy XIII-2 to be compatible with next generation consoles that their existing platform, Crystal Tools, could not handle.
