Singular Lot Objects are a multi-format filetype.

Format

Since all three of the possible formats use this same TypeID, the Block ID must be used to determine which type of Block is contained in the file.

The possible Block IDs are:

• 0xFA34F3EB : cPerson
• 0x7D4F2BB8 : cAnimatable
• 0xFA1C39F7 : cObject

The following is based Inge's 2007 november note.

64 BYTEs - Zeroes

• • • cPerson section starts here, if not person, we move straight on to cAnimatable section

DWORD - Type of record (0x FA34F3EB=cPerson)

DWORD - probably version

BYTE - STRING length

STRING - Type of table ("cPerson")

• • • cLocomotable section starts here, if not Locomotable, we move straight on to cAnimatable section

DWORD - Type of record (0xFD4F2EC7=cLocomotable)

DWORD - probably version

BYTE - STRING length

STRING - Type of table ("cLocomotable")

• • • cAnimatable section starts here, if not animatable, we move straight on to cObject section

DWORD - Type of record (0x7D4F2BB8 = cAnimatable)

DWORD - probably version (usually 1000 0000)

BYTE - STRING length

STRING - Type of table ("cAnimatable")

• • • cObject section starts here

DWORD - Type of record (0xFA1C39F7 = cObject)

DWORD - probably version (1100 0000)

BYTE - STRING length

STRING - Type of table ("cObject")

BYTE - STRING length

STRING - model name from STR#85. Can be 0 length if no model name

DWORD - Count of entries

__Main entry starts__

BYTE - STRING length

STRING - Unk

DWORD - Unk (from the CRES cResourceNode, Settings, "Unknown 2"?)

DWORD - Count of subentries

___Subentry starts____

BYTE - STRING length

STRING - material

BYTE - STRING length

STRING - mesh subset

___Subentry ends___

__Main entry ends___

• • • Main Coords (Main coords are relative to lot)

FLOAT - X coord

FLOAT - Y coord

FLOAT - Height in metres

8 BYTEs - Unk (nearly always 0)

4 BYTEs - Rotation quaternion Y

4 BYTEs - Rotation quaternion W

DWORD - count of entries which I think are CRES nodes.

Entry #1's coordinates are relative to the lot. They change if the object is moved on the lot. The subsequent entries I believe are relative to the Entry #1.

___Entry starts___

BYTE - STRING length

STRING - node name

FLOAT - X coord

FLOAT - Y coord

FLOAT - Height in metres

8BYTEs - Unk (almost always 0)

4 BYTEs - Rotation quaternion Y

4 BYTEs - Rotation quaternion W

___Entry ends___

DWORD - count of blend pair entries (whatever they are)

___Entry starts____

BYTE - STRING length

STRING - blend name

BYTE - STRING length

STRING - blend partner

DWORD - terminal zeroes

___Entry ends___

• • • cObject data ends here and cAnimatable data restarts

8 bytes (always seems to be 0000 803F 0100 0000)

_Set of coords_ (current - changes when moved)

FLOAT - X coord

FLOAT - Y coord

FLOAT - Height in metres

8BYTEs - Unk (nearly always 0)

4 BYTEs - Rotation quaternion Y

4 BYTEs - Rotation quaternion W

_Set of coords_ (current - usually identical to set above)

FLOAT - X coord

FLOAT - Y coord

FLOAT - Height in metres

8BYTEs - Unk (nearly always 0)

4 BYTEs - Rotation quaternion Y

4 BYTEs - Rotation quaternion W

_Set of coords_ (does not seem to change with move)

FLOAT - X coord

FLOAT - Y coord

FLOAT - Height in metres

8BYTEs - Unk (nearly always 0)

4 BYTEs - Rotation quaternion Y

4 BYTEs - Rotation quaternion W

_Set of coords_ (previously saved position)

FLOAT - X coord

FLOAT - Y coord

FLOAT - Height in metres

8BYTEs - Unk (nearly always 0)

4 BYTEs - Rotation quaternion Y

4 BYTEs - Rotation quaternion W

DWORD - count of anim entries

___Entry starts____

16 BYTES - Unk

BYTE - STRING length

STRING - anim-related string

BYTE - STRING length

STRING - bone? joint?

377 BYTES - Unk

BYTE - STRING length

STRING - another anim-related string

4 BYTEs - Unk

___Entry ends___

DWORD - (Only in cPerson - zeroes - may be cLocomotable record terminator)

DWORD - (Only in cPerson - zeroes - may be cPerson record terminator)
