Typedefs
template<ClientVersion V>
using	SMOBatch = detail::SMOBatch<canonicalVersion(V, WmoBatchPivots, WmoVersions)>
	A MOBA render batch — the canonicalizing face of detail::SMOBatch (WmoBatchPivots: the culling box gives way to the large material id at Legion), so two instantiations cover all eleven releases.
template<ClientVersion V>
using	SMOGroupHeader = detail::SMOGroupHeader<canonicalVersion(V, WmoGroupHeaderPivots, WmoVersions)>
	The MOGP header — the canonicalizing face of detail::SMOGroupHeader (WmoGroupHeaderPivots: the split-group indices arrive at 9.2), so two instantiations cover all eleven releases.

Typedef Documentation

SMOBatch

template<ClientVersion V>

using wowlib::formats::wmo::group::chunks::SMOBatch = detail::SMOBatch<canonicalVersion(V, WmoBatchPivots, WmoVersions)>

A MOBA render batch — the canonicalizing face of detail::SMOBatch (WmoBatchPivots: the culling box gives way to the large material id at Legion), so two instantiations cover all eleven releases.

Definition at line 143 of file geometry.hpp.

SMOGroupHeader

template<ClientVersion V>

using wowlib::formats::wmo::group::chunks::SMOGroupHeader = detail::SMOGroupHeader<canonicalVersion(V, WmoGroupHeaderPivots, WmoVersions)>

The MOGP header — the canonicalizing face of detail::SMOGroupHeader (WmoGroupHeaderPivots: the split-group indices arrive at 9.2), so two instantiations cover all eleven releases.

Definition at line 201 of file header.hpp.

Enumeration Type Documentation

GroupFlags

enum class wowlib::formats::wmo::group::chunks::GroupFlags : std::uint32_t

strong

Group flag bits (MOGP and MOGI flags).

Enumerator
HasBsp	Has a collision BSP tree (MOBN/MOBR).
HasLightMap	Has a light map (v14 legacy; unused since vanilla).
HasVertexColors	Has vertex colors (MOCV).
Exterior	Outdoor group (SMOGroup::EXTERIOR).
ExteriorLit	Use exterior lighting; no local diffuse.
Unreachable	Unreachable (SMOGroup::UNREACHABLE).
ShowExteriorSky	Show the exterior sky inside this interior group.
HasLights	Has light references (MOLR).
Lod	Legion+: an LOD group. Pre-Cata: marked the unused MPB* chunks.
HasDoodads	Has doodad references (MODR).
HasLiquid	Has liquid (MLIQ), or an implicitly full volume.
Interior	Indoor group (SMOGroup::INTERIOR).
QueryMountAllowed	Pre-WotLK: whether mount queries are allowed.
AlwaysDraw	Always draw (clears exterior after group creation).
HasTriangleStrips	Has triangle-strip data (MORI/MORB).
ShowSkybox	Show the skybox; unset automatically when MOSB is absent.
Ocean	The liquid is ocean, not water (LiquidType handling).
MountAllowed	Mounting is allowed in this group.
HasTwoMocv	Has a second MOCV layer; only its alpha is used.
HasTwoMotv	Has two MOTV texcoord sets (SMOGroup::TVERTS2).
Antiportal	An antiportal occluder group (SMOGroup::ANTIPORTAL).
ExteriorCull	Exterior culling (SMOGroup::EXTERIOR_CULL, Legion+).
HasThreeMotv	Has three MOTV texcoord sets, e.g. for shader 18.

Definition at line 22 of file header.hpp.

GroupFlags2

enum class wowlib::formats::wmo::group::chunks::GroupFlags2 : std::uint32_t

strong

Extended group flag bits (MOGP.flags2 and MGI2).

Enumerator
CanCutTerrain	Has terrain-cutting portal planes (MOPL, WoD+).
IsSplitGroupParent	Parent of a split group (9.2+).
IsSplitGroupChild	Child of a split group (9.2+).
AttachmentMesh	An attachment mesh (9.2 - 11.0).

Definition at line 60 of file header.hpp.

PolyFlags

enum class wowlib::formats::wmo::group::chunks::PolyFlags : std::uint8_t

strong

Per-triangle flag bits (MOPY and MPY2).

Enumerator
Transition	A transition face, blending exterior and interior lighting.
NoCamCollide	The camera does not collide with this face.
Detail	A detail face.
Collision	Collision-only (also turns off water ripples).
Hint	A hint face.
Render	A rendered face.
CullObjects	Enables game-object culling against this face.
CollideHit	Collides with projectiles/hit tests.
