As specified in WDB.

DWORD

Block ID

Value = 8A84D7B0

DWORD

Block version

Only known value is 1

7BITSTR

Block name

Value = "cWallLayer"

Data Section

instance 0x04 (used by wall partitions)

DWORD

Count N

repeat N times

Number of partition instance(s) (different partition types included)

DWORD

ID of the partition instance

Corresponds to partition instance ID in WGRA List of Walls

DWORD

Partition Type (walls, fences, half-walls, fencearches, etc)

There are two possible values for this field:

1) Wall or partition type specified in walls.txt, and possibly other files such as fences.txt. For example:

1 = normal wall

3 = attic wall

23 = brick foundation wall

29 = pool wall

2) Some other hex value; meaning not known at this time.

WORD

Wall covering on one side of the wall

WORD

Wall covering on the other side of the wall

instance 0x12 (used for fence-arch)

DWORD

Count N

repeat N times

Number of partition instance(s) (different partition types included)

DWORD

ID of the partition instance

Corresponds to partition instance ID in WGRA List of Walls

WORD

Partition Type (walls, fences, half-walls, fencearches, etc)

There are two possible values for this field:

1) Wall or partition type specified in walls.txt, and possibly other files such as fences.txt. For example:

1 = normal wall

3 = attic wall

23 = brick foundation wall

29 = pool wall

2) Some other hex value; meaning not known at this time.

DWORD

apparently, a grid point location

WORD

unknown

Note:

1) Each partition instance ID may be reflected in multiple WGRA instances.

2) WLL is also known as WLAY in SimPE

3) SMAP can be used to translate the two wall covering numbers from WLL to two 7BITSTR. If a 7BITSTR appears to be a GUID, an XOBJ record in catpatterns.bundle.package may be used to translate this GUID to an actual wall covering. For example, a 7BITSTR value of "4CD64CEA" can be found as the GUID for "Way Off White" Paint.
