Quest3D saves a layout (IGR) file along with each Quest3D Channel Group (.CGR) file. The IGR file defines the locations of all channels within the Quest3D Channel Graph layout pane. It saves the user-defined layout of a 3D scene.

IGR files have the same filename as the corresponding CGR file, except for the file extension. A CGR file may still be opened if the IGR file is not available, but the default layout will be used, which may cause the 3D scene to appear incorrectly.
