A set of importers accept a variety of formats of 2D and 3D content (source asset) for computer games in the format created by the artists' authoring tool. The source asset is standardized and normalized and is stored as a strongly typed object in a content object model. An object from the content object model can be deserialized to a file for debugging. The object can be converted to a managed object to which game code can be written. An executable object is generated from the object created during game development automatically.
