Namespaces
namespace	bone
	The .bone facial-pose file entity (WoD+).
namespace	chunked
	The Legion+ chunked .m2 shell (M2ChunkedFile) with its per-version classes and the companion-chunk payload records (AFID entries, extended particles, parent-model overrides).
namespace	detail
	A shared model skeleton (.skel, 7.3+): the bones, attachments and sequences a skel-based model moved out of its MD20 image, plus the satellite ids.
namespace	root
	The MD20 model body (M2Root) with its per-version classes.
namespace	skin
	The external LOD view entity (.skin file, WotLK+) and the skin profile records (submeshes, render batches).

Classes
class	AnimBuffers
	The per-sequence external write buffers every M2-family write path shares: an external sequence's data lands in its own per-key buffer as the tracks route their blocks through sink(); inline sequences (and aliases, whose flags never mark them external) stay in the entity image. More...
class	AnimCache
	A lazy per-sequence .anim loader handing out resolution windows: for a chunked file (leading AFM2) the requested chunk's payload, for a raw file the whole content when AFM2 is asked for (raw files predate the split sections). More...
struct	BoneFile
	One .bone file: which bones get facial-pose offset matrices, and the matrices. More...
struct	M2Base
	The version-agnostic base of every M2<V> (welded as "M2"). More...
struct	M2OffsetBase
	The non-template marker base every offset block carries (what the OffsetEntity concept detects). More...
struct	M2OffsetBlock
	The serialization face of an offset block, mixed in CRTP-style: an entity struct E : M2OffsetBlock<E> gains read()/write() plus the imageSize() and memberOffset() layout queries. More...
struct	OffsetReadContext
	Resolution of SequenceData members while reading: where each outer element's nested data lives. More...
struct	OffsetWriteContext
	Resolution of SequenceData members while writing: which buffer each outer element's nested data blocks are appended to (offsets recorded relative to that buffer). More...
class	SatellitePaths
	The satellite-file naming conventions around one model path: every companion file of "creature\\x\\x.m2" derives from the same stem. More...
struct	SequenceKey
	A sequence's satellite identity: the (animation id, variation) pair the .anim naming convention ("{stem}AAAA-SS.anim") and the AFID entries key on. More...
struct	SkeletonBase
	The version-agnostic base of every Skeleton<V> (welded as "Skeleton"). More...
struct	SkelParentData
	The SKPD payload: the parent-skeleton link used for de-duplication (e.g. More...

Concepts
concept	OffsetStringMember
	A member serialized as an M2Array<char>: its bytes (NUL included) live in a data block, referenced by an M2Array{count, offset} slot.
concept	OffsetArrayMember
	A member serialized as an M2Array{count, offset} reference to a separate data block — a std::vector (the block holds its element images) or a std::string.
concept	InlineRecordMember
	A member serialized inline as a nested record: a non-trivial class the walker recurses into member-by-member at the current cursor (M2Track and friends).
concept	InlineScalarMember
	A member serialized as inline raw bytes: anything trivially copyable that is not an array/string reference (scalars, C3Vector, M2Range, …).
concept	OffsetEntity
	A type the offset engine can read and write: it is an M2 offset block and declares the client version it is laid out for.

Typedefs
template<ClientVersion V>
using	M2ChunkedFile = chunked::M2ChunkedFile<canonicalVersion(V, M2FilePivots, M2ChunkedVersions)>
	The chunked .m2 stream — the canonicalizing face of chunked::M2ChunkedFile: every Legion+ version maps to its range's first grid version (M2FilePivots — the active chunk set is constant within a range).
template<ClientVersion V>
using	M2 = detail::M2<canonicalVersion(V, M2AssemblyPivots, M2Versions)>
	A whole model — the canonicalizing face of detail::M2: every client version maps to its range's first grid version (M2AssemblyPivots), so one instantiation serves e.g.
template<ClientVersion V>
using	M2Root = root::M2Root<canonicalVersion(V, M2DataPivots, M2Versions)>
	The MD20 body — the canonicalizing face of root::M2Root: every client version maps to its range's first grid version (M2DataPivots), so one instantiation serves e.g.
template<ClientVersion V>
using	SkelHeader = detail::SkelHeader<canonicalVersion(V, M2ChunkPayloadPivots, M2ChunkedVersions)>
	The SKL1 payload — canonicalizing face of detail::SkelHeader.

	The SKS1 payload — canonicalizing face of detail::SkelSequences.

template<ClientVersion V>
using	Skeleton = detail::Skeleton<canonicalVersion(V, M2ChunkPayloadPivots, M2ChunkedVersions)>
	A shared model skeleton — the canonicalizing face of detail::Skeleton: the whole chunked era is one range (M2ChunkPayloadPivots is empty), so a SINGLE instantiation serves Legion through the latest release.
template<ClientVersion V>
using	Skin
	An external LOD view — the canonicalizing face of detail::Skin: every WotLK+ version maps to its range's first grid version (M2SkinPivots: only Cata's shadow batches split the era, so two instantiations cover all nine releases).

Enumerations
enum class	GlobalFlags
	M2Root::globalFlags bits. More...

Functions
consteval std::uint32_t	m2FormatVersion (ClientVersion v)
	The MD20 formatVersion wowlib writes for v — the value the client era itself exports (wowdev.wiki/M2, the Versions section): vanilla 256, TBC 263, WotLK 264, Cata through WoD 272, Legion+ 274.
consteval std::pair< std::uint32_t, std::uint32_t >	m2FormatVersionRange (ClientVersion v)
	The inclusive MD20 version range a client era's files may carry — reading accepts the whole era (a 2.4.3 client still ships v260 models), writing always emits m2FormatVersion().
template<typename T, ClientVersion V>
consteval std::size_t	layoutSize ()
	The image footprint of T in an offset layout for client version V: the 8-byte M2Array slot for an array/string reference, sizeof for an inline scalar, and the version-active member sum for an inline record (client records have no implicit padding, so the sum IS the layout).

Variables
constexpr ClientVersion	M2CompressedBones = builds::TBC
	TBC (v260+): bone rotations become compressed M2CompQuat (vanilla stored raw C4Quaternion), M2CompBone gains the boneNameCRC field, and the particle header packs blendingType/emitterType into bytes next to the new particleColorIndex (late-TBC v262 in the format; TBC's last minor 2.4.3 writes v263, so the whole tbc target is past it).
constexpr ClientVersion	M2PerSequenceTimelines = builds::WotLK
	WotLK (v264): every M2Track nests one timestamp/value array per sequence (the vanilla single timeline with interpolation ranges is gone), M2Sequence stores a duration instead of global start/end timestamps, skin profiles move out to .skin files and low-priority sequences to .anim files, particles gain the FBlock color/scale tracks and the four spin fields, ribbons their priority-plane tail.
constexpr ClientVersion	M2MultitexParticles = builds::Cata
	cata (v272): particles turn multi-textured (492-byte record: texture id bitfield, multiTexScale replacing particleType/headOrTail, the multiTexScroll tail) and cameras trade the static diagonal FOV for a spline track.
constexpr ClientVersion	M2SplitBlendTimes = builds::WoD
	WoD (6.0.1): M2Sequence's u32 blendTime splits into the blendTimeIn/blendTimeOut pair.
constexpr ClientVersion	M2ChunkedContainer = builds::Legion_Alpha
	legion (7.0.1.20740): the on-disk .m2 becomes a chunked file — the MD20 image moves into the MD21 chunk (offsets stay relative to the image) joined by the companion chunks (PFID/SFID/AFID/…, forward fourccs).
constexpr ClientVersion	M2ChunkedOnly = builds::BfA
	BfA (8.0.1): the chunked container is universal — Legion clients still served leftover raw MD20 models, but from 8.0 on none exist, so BfA+ reads treat a bare MD20 magic as a version mismatch instead of falling back to the monolithic path.
constexpr std::array	M2Versions
	The versions M2 is instantiated (and welded) for: every targeted last-minor-of-major release, in release order.
constexpr std::array	M2SkinVersions
	The era subset .skin files exist for (WotLK+).
constexpr std::array	M2ChunkedVersions
	The era subset the chunked container exists for (Legion+).
constexpr std::array	M2TrackPivots {M2PerSequenceTimelines}
	Track-shaped records (M2Track, M2TrackBase, and every record whose only version axis is the tracks it embeds: colors, weights, transforms, flipbooks, attachments, events, lights, ribbons — the ribbon's WotLK trailing fields share the same pivot).
constexpr std::array	M2SequencePivots {M2PerSequenceTimelines, M2SplitBlendTimes}
	M2Sequence: timestamps→duration at WotLK, blend-time split at WoD.
constexpr std::array	M2BonePivots {M2CompressedBones, M2PerSequenceTimelines}
	M2CompBone: raw→compressed quaternions + name CRC at TBC, per-sequence track timelines at WotLK.

constexpr std::array	M2ParticlePivots {M2CompressedBones, M2PerSequenceTimelines, M2MultitexParticles}
	M2Particle: byte-packed blending/emitter types at TBC, FBlock ramps and spins at WotLK, the multi-texture 492-byte layout at Cata.
constexpr std::array	M2SkinSectionPivots {M2CompressedBones}
	M2SkinSection: the sort center/radius tail at TBC.
constexpr std::array	M2SkinProfilePivots {M2CompressedBones, M2MultitexParticles}
	M2SkinProfile: the section layout at TBC, shadow batches at Cata.
constexpr std::array	M2SkinPivots {M2PerSequenceTimelines, M2MultitexParticles}
	The Skin entity (.skin files, WotLK+): its existence boundary plus the profile's Cata shadow batches.
constexpr std::array	M2DataPivots
	M2Root (the MD20 body): the union of every record pivot, its own trait slots (TBC combos, WotLK external skins) and the format-version steps (263/264/272/274).
constexpr std::array	M2FilePivots
	M2ChunkedFile (the chunked stream): every chunk-introduction build — each documented since() value, so the active chunk set is constant within a range.
constexpr std::array< ClientVersion, 0 >	M2ChunkPayloadPivots {}
	Skeleton and its chunk payloads plus the shell payload records: stable across the whole chunked era — no pivots, one instantiation.
constexpr std::array	M2AssemblyPivots
	The M2 assembly: the union of the body, skin and stream pivots plus the bare-MD20 read gate (M2ChunkedOnly).

Function Documentation

◆ layoutSize()

template<typename T, ClientVersion V>

std::size_t wowlib::formats::m2::layoutSize ( )

consteval

The image footprint of T in an offset layout for client version V: the 8-byte M2Array slot for an array/string reference, sizeof for an inline scalar, and the version-active member sum for an inline record (client records have no implicit padding, so the sum IS the layout).

Element kinds recurse, so vector<vector<u32>> and vector<Record> fall out naturally. gatedBy members are rejected inside records: their presence is runtime state, supported only at the entity top level (see M2OffsetBlock::imageSize).

Template Parameters

T	the member/record type to measure.
V	the client version the layout targets.

Returns: the number of bytes T occupies in place.

std::pair< std::uint32_t, std::uint32_t > wowlib::formats::m2::m2FormatVersionRange ( ClientVersion v )

consteval

The inclusive MD20 version range a client era's files may carry — reading accepts the whole era (a 2.4.3 client still ships v260 models), writing always emits m2FormatVersion().
