Vertex Buffer

Vertex buffers were used alongside index buffers in renderable meshes. Their only known use is in Black 2 (2006-06-29 build); the type was deprecated by the time Burnout 5 (2006-11-13 build) was built.

Note that because this is a standalone resource type, indices and vertices are completely separate. This is unlike its modern counterpart, where they reside together in a single buffer.


This listing defines types for Xbox 360 only. For other platforms, although the modern format is not identical, it is similar. See Renderable.


Offset Length Type Name Description Comments
0x0 0x4 uint32_t ? D3D resource type May have highest nibble as a flag
0x4 0x4 uint32_t ? Always 1?
0x8 0x4 ? ?
0xC 0x4 ? ?
0x10 0x4 ? ?
0x14 0x2 int16_t ? Always -1?
0x16 0x2 Padding
0x18 0x4 uint32_t ? Start offset + 3
0x1C 0x4 uint32_t ? Buffer size + 2 May have highest nibble as a flag

This is followed by the array header.

Array header

Offset Length Type Name Description Comments
0x0 0x2 uint16_t ? Combined length of this header and values
Same as in mesh state
0x2 0x1 uint8_t ? Number of values
0x3 0x1 ? ? Padding?
0x4 0x4 uint32_t ?

The values this stores are possibly flags, though none of the fields are known.
