Sims 3:0x9063660E

World - Roads & Walkways
TypeID:	0x9063660E
Game Version:	The Sims 3

Overview

While this data very clearly defines the roads and walkways as well as everything needed to procedurally generate them on the terrain, it is unclear how it is actually used. Replacing/altering it in a world file had no effect on navigation or rendering of roads.

Sample street map for Sunset Valley interpreted from 0x9063660E data.

Format

DWORD version 7
WORD R-I-count
WORD W-I-count
WORD R-C-count
WORD W-C-count
REP R-I-count (Road intersections)
    FLOAT X
    FLOAT Y
    FLOAT Angle
    10 BYTES blank
    BYTE connectioncount
    REP connectioncount
        BYTE direction
        WORD index
        BYTE
REP W-I-count (walkway intersections)
    (Same format as R-I section)
REP R-C-count (Road curves)
    8 FLOAT curve (Defines the four points for a bezier curve)
    8 BYTES blank
    BYTE connectioncount
    REP connectioncount
        BYTE direction
        WORD index
        BYTE
REP W-C-count (Walkway curves)
    (Same format as R-C section)
6 WORDS (All 1)
REP 6 (Seems to be constant, can't find anywhere 6 is named)
    TGI64 texture diffuse map
    TGI64 texture bump map
    FLOAT width?
    FLOAT height?

The connection indexes are 1-based and index across the entire list of curves and intersections. So 1..R-I-count is a connection to a road intersection, R-I-count + 1..R-I-count+W-I-count is a reference to a walkway intersection, etc.
