.CGR File Association 2

File created by Quest3D, an engine used to create 3D programs; contains a group of "channels," or properties for the flow and display of objects, models, surfaces, textures, properties, and animations; used to store product visualizations, games, tutorials, animations, user interfaces, and immersive environments.

More Information

CGR files are always stored with complementing .IGR files, which contain the location of channels within the Quest3D Channel Graph layout pane. If the IGR files are missing, the channels will use a default layout and may be difficult to view.

CGR files are used in games such as Audiosurf, Leo, and The Endless Forest.
