What game engine is listed for Rayman Origins?

The game engine listed for Rayman Origins is the UbiArt Framework.

Developed by Ubisoft Montpellier, the UbiArt Framework was designed to turn illustrated 2D artwork and animation into interactive game worlds with relatively little conventional coding. Rayman Origins showcases that approach through hand-drawn visuals, fluid animation, layered backgrounds, and a bright, painterly style.

The framework is often described as a 2.5D engine: the art is primarily two-dimensional, but the game combines it with scrolling, depth effects, physics, and three-dimensional gameplay structure. Its tools were intended to let artists and animators work directly in an interactive environment.

Rayman Origins began as a smaller, episodic project before becoming a full retail game. Released in 2011, it was the first major Rayman title since Rayman 3: Hoodlum Havoc and helped establish the visual and technical foundation later used by Rayman Legends.
