Name Type Arg Arr1 Arr2 Cond Description FromTo
From NiObject
From NiGeometryData
Unknown Int int Unknown identifier. Always 0. 10.2.0.0
Num Vertices ushort !IsDerivedType(NiPSysData::TYPE) Number of vertices.
Num Vertices ushort IsDerivedType(NiPSysData::TYPE) Number of vertices.
BS Max Vertices ushort IsDerivedType(NiPSysData::TYPE) Bethesda uses this for max number of particles in NiPSysData.
Keep Flags byte Used with NiCollision objects when OBB or TRI is set. 10.1.0.0
Compress Flags byte Unknown. 10.1.0.0
Has Vertices bool Is the vertex array present? (Always non-zero.)
Vertices Vector3 Num Vertices hasVertices The mesh vertices.
Num UV Sets ushort Flag for tangents and bitangents in upper byte. Texture flags in lower byte.
BS Num UV Sets ushort Bethesda's version of this field for nif versions 20.2.0.7 and up. Only a single bit denotes whether uv's are present. For example, see meshes/architecture/megaton/megatonrampturn45sml.nif in Fallout 3.
Unknown Int 2 uint !IsDerivedType(NiPSysData::TYPE) Unknown, seen in Skyrim. 20.2.0.7
Has Normals bool Do we have lighting normals? These are essential for proper lighting: if not present, the model will only be influenced by ambient light.
Normals Vector3 Num Vertices hasNormals The lighting normals.
Tangents Vector3 Num Vertices hasNormals && ((numUvSets & 61440) || (bsNumUvSets & 61440)) Tangent vectors. 10.1.0.0
Bitangents Vector3 Num Vertices hasNormals && ((numUvSets & 61440) || (bsNumUvSets & 61440)) Bitangent vectors. 10.1.0.0
Center Vector3 Center of the bounding box (smallest box that contains all vertices) of the mesh.
Radius float Radius of the mesh: maximal Euclidean distance between the center and all vertices.
Unknown 13 shorts short 13 Unknown, always 0? 20.3.0.9 20.3.0.9
Has Vertex Colors bool Do we have vertex colors? These are usually used to fine-tune the lighting of the model.

Note: how vertex colors influence the model can be controlled by having a NiVertexColorProperty object as a property child of the root node. If this property object is not present, the vertex colors fine-tune lighting.

Note 2: set to either 0 or 0xFFFFFFFF for NifTexture compatibility.
Vertex Colors Color4 Num Vertices hasVertexColors The vertex colors.
Num UV Sets ushort The lower 6 (or less?) bits of this field represent the number of UV texture sets. The other bits are probably flag bits. For versions 10.1.0.0 and up, if bit 12 is set then extra vectors are present after the normals. 4.2.2.0
Has UV bool Do we have UV coordinates?

Note: for compatibility with NifTexture, set this value to either 0x00000000 or 0xFFFFFFFF.
4.0.0.2
UV Sets TexCoord Num UV Sets & 63 Num Vertices The UV texture coordinates. They follow the OpenGL standard: some programs may require you to flip the second coordinate.
Consistency Flags ConsistencyType Consistency Flags 10.0.1.0
Consistency Flags ConsistencyType !IsDerivedType(NiPSysData::TYPE) Consistency Flags 10.0.1.0
Additional Data Ref<AbstractAdditionalGeometryData> Unknown. 20.0.0.4
