Clump (RW Section)
|RW Stream Section|
A Clump is a container for Frames, Atomics, Light and Cameras.
In a binary stream a Clump's child chunks are a Struct (described below), a Frame List, a Geometry List, a number of Atomics, optionally a number of Structs and Lights and a number of Structs and Cameras (Cameras are unused in GTA).
Mulitple Clumps may appear inside one
.dff file. There is no counting variable stored inside the file defining how many Clumps are stored inside it.
Cameras and Lights as part of Clumps were first introduced after version
0x33000 and below do not have them.
The Clump's Struct has the following format:
int32 - Number of Atomics int32 - Number of Lights - only present after version 0x33000 int32 - Number of Cameras - only present after version 0x33000 but 0 in all GTA files
Following the struct are a Frame List and a Geometry List. After that a number of Atomics as given by the atomic count. If the Clump has lights or cameras, next come pairs of Structs and Lights and Structs and Cameras respectively. In both cases the Struct contains a 4 byte index into the Frame List for the Frame the Light or Camera should be attached to.
Before version 0x30400 (
loplyguy.dff in GTA III, version
0x30200) the structure is a little different. The Clump has no Geometry List and the Geometries are children of their respective Atomic chunks (and consequently the Atomic Struct is 4 bytes shorter for having no geometry index).
