Rig Resource - _RIG
TypeID:0x8EAF13DE
Game Version:The Sims 3



Contents

Overview

The RIG file has gone through some changes over the years. There was once the proprietary GR2 format, but it has since been replaced with EA's own format that is much easier to deal with. At this point, the olde format should never be used. It has been deprecated by patches and expansions, and new versions of the base game rig files can be found in DeltaBuild0.package. Pets in their own EP were made using the new format as well.


There were previously three 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.
    • Get "Granny Viewer" from the altervista downloads page and you can load the data (export it as 'somefile.gr2').
    • Also related is this thread on Xentax.
  • A second format exists, where the Granny data is wrapped with some additional fields.
  • Starting with the Create A Pet Demo, there is a new third format that is unencrypted.


Olde 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:

Rick adds:

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

New Format

Starting with the Create A Pet Demo, there is a new third format of RIG files that is unencrypted. Version 3 contains no IK data, and zero-length skeleton name.

Format

DWORD Major Version? //3-4
DWORD Minor Version? //1-2
DWORD Bone Count
--repeat(Bone Count)
    FLOAT[3] Position
    FLOAT[4] Orientation //Quaternion 
    FLOAT[3] Scaling?
    DWORD Bone Name Length
    STRING (Bone Name Length ASCII characters)
    DWORD ??? // Something to do with mirrored bones.  It will be the same as the bone's index except in the case of Left/Right mirrored bones it is the index of it's opposite
    DWORD Parent Index
    DWORD Bone Name Hash (FNV 32)
    DWORD Flags? //Usually 0x23, except with mirrored bones, then one will be 0x3F
DWORD Skeleton Name Length
STRING (Skeleton Name Length ASCII characters)
--if(Version >= 4)
    DWORD IK Chain Count
    --repeat(IK Chain Count)
        DWORD Length
        --repeat(Length)  
            DWORD BoneIndex //bone index  
        DWORD InfoNode[11] //bone index 
        DWORD PoleVector //bone index 
        DWORD SlotInfo //bone index 
        DWORD SlotOffset //bone index 
        DWORD Root //bone index
