<code>WOBJ</code> can be listed multiple times, but its section index is always 0 (pointing to the materials section). Every other section number always appears in every MREA file once (none are optional). Here are all possible section numbers and what they are, in the order that they appear in the file: | <code>WOBJ</code> can be listed multiple times, but its section index is always 0 (pointing to the materials section).

This section is basically a list of all resources that this area depends on, not unlike a [[DGRP (File Format)|DGRP]] file. After the initial dependency list, there's a second array which provides a list of offsets into the dependency list. These offsets are used to indicate which dependencies are needed for individual script layers, with the last offset pointing to resources that are used by the area itself as a whole (world geometry textures and the [[#Path|PATH]]/[[#Portal Area|PTLA]]/[[#Static Geometry Map|EGMC]] assets). | This section is basically a list of all resources that this area depends on, not unlike a [[DGRP (File Format)|DGRP]] file.
