Contents

Scenegraph File Format Specification

RCOL, or Scenegraph Resource Collection, is a Sims 2 data type that contains numerous, arbitrary data blocks containing a variety of information.

This information is primarily used for objects, animation, textures, and the like. The file is composed of a header (somewhat confusing), and one or more data blocks. Each data block can have multiple sections or can even be recursive in nature.

After reading the header and the index, each data block must be read according to its own specification. The specifications for each possible type of data block follow the first part of this specification.

IMPORTANT NOTES: To further explain a strange quirk of this file type. The header has two possible configurations that are not readily apparent. In the specification below, the first two WORDs, "Language" and "String Format", may not be present. If, when parsing raw data of an RCOL, the first 4 bytes when read as a DWORD are not 0xFFFF0001, then reading must BACKTRACK, and reread the first 4 bytes as the "File Links" DWORD. If, when parsing, you DID backtrack and the first two WORDs are not present, then when reading "File Links", you must read only a TGI, not a TGIR (i.e. read 3 DWORDs per link, rather than DWORDs).

RCOL Header

Data Section Specifications

Each block ID# has a unique block name. Following are links to specifications for each known block type, by their TypeID and the translated type code (i.e. 0xAC4F8687/GMDC).
