Sims 3:0x8EAF13DE

RIG

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 (from start of file)
DWORD offset2			// To start of Granny data (from start of this DWORD)
DWORD chunk1offset		// To start first of "Int2" Chunk (from start of this DWORD)
--repetition 4 times:
	DWORD chunkOffset	// To start of 2nd to 5th "Int2" Chunk (from start of this DWORD)
--repetition 4 times:
	DWORD unusedOffset	// 0?

--insert Granny2 data

//"Int2" block:
//chunk1:
DWORD Count1
DWORD offset (from start of this DWORD)
--repetition Count1:
	QWORD type
	--if type == 00000000 03000000
		BYTE[144]
	--if type == 01000000 01000000
		BYTE[176]

--repetition 4 times:
	//chunks 2 to 5:
	DWORD count:
	--repetition count
		DWORD
