DCLN (Metroid Prime)

''This article is for the DCLN format from the Metroid Prime series and Donkey Kong Country Returns. See DCLN (File Format) for other revisions of this format.''

The DCLN format stores one or more collision meshes, each partitioned via an OBB tree. These are used as dynamic collision data for actors and platforms. Most of the format is shared with the MREA format, but there are some sections that are unique to DCLN.

Format
The file can store multiple collision meshes; each one has its own chunk in the file.
