g_chunk_pc

The GPU chunk file only contains vertex and index buffers. The file consists of two major parts:

Shared buffers section

Massive shared vertex and index buffers for static world geometry.

Contents:

• 0..n vertex buffers for each type of vertex. Type means the number of UV's and such in a vertex.
• A single index buffer for the above vertex buffers.

Individual models section

• The CPU chunk header contains a pointer to this section.
• The contents is obviously a bunch of models, but where exactly are the headers is not fully figured out.
• The shared buffer seems to return garbage for all "loose" and destroyable objects, so it's probably safe to assume this section is the one holding them instead.
