Classes
struct	wowlib::formats::adt::chunks::SMChunk
	The per-cell MCNK header — 128 bytes, memcpy'd verbatim. More...
struct	wowlib::formats::adt::chunks::MHDRData
	The tile header (MHDR, 64 bytes, root/monolithic). More...
struct	wowlib::formats::adt::chunks::MFBOPlanes
	The flying bounding box (MFBO, BC+): two 3x3 grids of int16 heights — a maximum plane you fall through and a minimum plane below the world. More...

Detailed Description

ADT header binary structs (namespace wowlib::formats::adt::chunks): the per-cell MCNK header (SMChunk, 128 bytes) and the flying bounding box (MFBO).

SMChunk carries many fields that are DERIVED from the cell's actual content — the sub-chunk offsets and sizes, the layer/ref/emitter counts. wowlib stamps those on write (MapChunk::write_slice) and hides them from the bindings (mark::exclude); the meaningful, user-authored fields (flags, indices, area, holes, the detail-doodad maps, the cell origin) stay exposed.
