Detailed Description

template<typename SrcMeshType>
class UE::Geometry::TToDynamicMesh< SrcMeshType >

Class used to convert a mesh with attributes (e.g. normals, uvs etc) to a FDynamicMesh3

The Source Mesh has to implement this interface

// attribute access that exploits shared attributes. // each group of shared attributes presents itself as a mesh with its own attribute vertex buffer. // NB: If the mesh has no shared Attr attributes, then Get{Attr}IDs() should return an empty array. // NB: Get{Attr}Tri() functions should return false if the triangle is not set in the attribute mesh.
