FMeshToMeshVertData
Namespace: UAssetAPI.PropertyTypes.Structs
A structure for holding mesh-to-mesh triangle influences to skin one mesh to another (similar to a wrap deformer)
public class FMeshToMeshVertData
Inheritance Object → FMeshToMeshVertData
Fields
PositionBaryCoordsAndDist
Barycentric coords and distance along normal for the position of the final vert
public Vector4PropertyData PositionBaryCoordsAndDist;
NormalBaryCoordsAndDist
Barycentric coords and distance along normal for the location of the unit normal endpoint. Actual normal = ResolvedNormalPosition - ResolvedPosition
public Vector4PropertyData NormalBaryCoordsAndDist;
TangentBaryCoordsAndDist
Barycentric coords and distance along normal for the location of the unit Tangent endpoint. Actual normal = ResolvedNormalPosition - ResolvedPosition
public Vector4PropertyData TangentBaryCoordsAndDist;
SourceMeshVertIndices
Contains the 3 indices for verts in the source mesh forming a triangle, the last element is a flag to decide how the skinning works, 0xffff uses no simulation, and just normal skinning, anything else uses the source mesh and the above skin data to get the final position
public UInt16[] SourceMeshVertIndices;
Weight
For weighted averaging of multiple triangle influences
public float Weight;
Padding
Dummy for alignment
public uint Padding;
