LandTable header format

This struct defines the number of models and animations in the level, the location of the corresponding lists, and the texture list used. The name comes from the label in the DLL Export table of various DLLs in the PC version of Sonic Adventure DX.

Offset Type Description
0 Short COL Count
2 Short Anim Count?
4 Int? Unknown
8 Int? Unknown
C Float Unknown, usually 3000
10 Pointer COL List
14 Pointer? Anim List?
18 Pointer Texture file name. Optional.

If not null, a PVM with this name will be loaded to the address pointed to by the texture list pointer.

1C Pointer Texture List

COL Format

The name COL is an antiquated misnomer, but for lack of a better name, it stuck. This data struct is a reference for loading a level model. It's 0x24 bytes long and works as follows:

Offset Type Description
0 Float[3] Center of collision sphere
C Float Radius of collision sphere
10 Pointer Model (OBJECT Struct)
14 8 Bytes Padding?
1C Int Surface Flags (see below)

Surface Flags

These flags are not entirely figured out yet, but here's what is known for sure:
0x80000000 = Visible
