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 [[Area Collision (File Format)|MREA format]], but there are some sections that are unique to DCLN.

__TOC__

== Format ==

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