SCAN (Metroid Prime 2)

This article is for the SCAN format from Metroid Prime 2 and 3. For other revisions of this format, see SCAN (File Format).

The SCAN file format describes scannable objects. The format's been updated since Prime 1; the data is now embedded into a script object, using the scriptable layers format. There was also some additional data added to the format to set up the model that displays in the logbook.

This file format is almost completely documented There's a couple remaining unknown parameters.

Format

The SCAN format sets up a small script layer that contains a single ScannableObjectInfo instance.
