Overview

There are two formats of the RIG file. The basic file content is a Granny 2 data file. Apart from the official tools, there are some user-contributed tools for manipulating the data on altervista. In addition, a second format exists, where the Granny data is wrapped with some additional fields.

Get "Granny Viewer" from the altervista downloads page and you can load the data (export it as 'somefile.gr2').

Format

Optional wrapper

There is an optional wrapper to the Granny data. This can be identified by the first DWORD in the file being 0x8EAF13DE (i.e. the resource type). The format is:

DWORD 0x8EAF13DE
DWORD 0
DWORD offset1			// To "Int2" block from start of Granny data
DWORD offset2			// To start of Granny data (from start of this DWORD)
DWORD IKChainsOffset		// To start first of "Int2" Chunk (from start of this DWORD)
DWORD IKTargetSlotsOffset	//(from start of this DWORD)
DWORD IKInfoNodeOffset		//(from start of this DWORD)
DWORD CompressNodeOffset	//(from start of this DWORD)
DWORD FullBoneListOffset	//(from start of this DWORD)
DWORD // unused offset?
DWORD // unused offset?
DWORD // unused offset?
DWORD // unused offset?

Granny2 Data

All offsets in this section start from the start of the Granny2 Data.

Rick adds:

The blobs that start with the following sequences are Granny2 data blocks:
