==Overview==
Format used by various resources in the Scenegraph.

==Format==
DWORD - Version
DWORD - Count of Internal Public Chunks (see [[Sims 4:RCOL#References|References]])
DWORD - Index3 (unused)
DWORD - ExternalCount
DWORD - InternalCount

//Internal Chunks: These are the TGIs that identify each chunk
-Repeat InternalCount Times
QWORD - I64
DWORD - TID
DWORD - GID

//External Resources: These are TGIs of referenced items (e.g. DDS Image)
-Repeat ExternalCount times
QWORD - I64
DWORD - TID
DWORD - GID

-Repeat InternalCount times
DWORD - Position of the Chunk (absolute)
DWORD - Size of the Chunk

===References===
Block references are 1 based (0 is reserved for null references), with a flag for the type of reference.

==Chunks==
The Type ID will also be the first chunk after the header(with the exception [[Sims_4:0x015A1849|GEOM]]).

===Resource Types===
These are the possible resource types, they are named by their first chunk.

Sims 4:RCOL - Revision history

ChaosMageX: Copied from Sims_3:RCOL and modified to point to resources for The Sims 4. JAZZ Chunks were removed as they no longer exist in TS4; their equivalent, Swing state machines, are XML instead of RCOL.
