Importer plug-ins are like export plug-ins except that they inherit from the SceneExport class instead of the GUP class.

An exporter plug-in must implement the following virtual functions:

• SceneImport::ExtCount() - The number of supported file extensions
• SceneImport::Ext() - The nth file extension without leading ".". E.g. "txt" instead of ".txt"
• SceneImport::LongDesc() - A detailed file output description.
• SceneImport::ShortDesc() - A short description of the exported file type, which appears in file save dialog.
• SceneImport::AuthorName() - A long description of the exported file type.
• SceneImport::CopyrightMessage() - A copyright message.
• SceneImport::OtherMessage1() - A message string.
• SceneImport::OtherMessage2() - Another message string.
• SceneImport::Version() - The version number of the export plug-in. The format is the major number times 100 plus the minor version. E.g. version 1.03 would be represented as 103.
• SceneImport::ShowAbout() - Called in response to display an about box.
• SceneImport::DoImport() - Perform the file import.
