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 - cPerson Version (only known value = 3)

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 - cLocomotable version (only known value = 4)

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 - cAnimatable version (known values: 14, 15, 16, 17)

BYTE - STRING length

STRING - Type of table ("cAnimatable")

• • • cObject section starts here

DWORD - Type of record (0xFA1C39F7 = cObject)

DWORD - cObject version (known values: 15, 16, 17)

BYTE - STRING length

STRING - Type of table ("cObject")

7BITSTR - 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

16 BYTEs - Rotation quaternion

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

16 BYTEs - Rotation quaternion

___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

FLOAT

value normally 1, but values as low as .94 have been seen

DWORD

value always 1

_Set of coords_ (current - changes when moved)

FLOAT - X coord

FLOAT - Y coord

FLOAT - Height in metres

16 BYTEs - Rotation quaternion

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

FLOAT - X coord

FLOAT - Y coord

FLOAT - Height in metres

16 BYTEs - Rotation quaternion

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

Note: if cAnimatable version is 14 or 15, then this entry is only 6 DWORDS, not 7, so it's not clear that this is actually a set of coordinates.

FLOAT - X coord

FLOAT - Y coord

FLOAT - Height in metres

16 BYTEs - Rotation quaternion

_Set of coords_ (previously saved position)

FLOAT - X coord

FLOAT - Y coord

FLOAT - Height in metres

16 BYTEs - Rotation quaternion

Note: If cAnimatable version is 14 or 15, then the following table of anim entries does not exist.

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 cLocomotable - zeroes - may be cLocomotable record terminator)

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