IDatasmithMeshElement defines an actual geometry. It won't add any instance to your scene, you'll need IDatasmithMeshActorElement for this. Notice that several IDatasmithMeshActorElements could use the this geometry.

const TCHAR * GetFile()	Get the output filename, it can be absolute or relative to the scene file	IDatasmithSceneElements.h
FMD5Hash GetFileHash ()	Return a MD5 hash of the content of the Mesh Element.	IDatasmithSceneElements.h
float GetHeight()	Get the bounding box height	IDatasmithSceneElements.h
int32 GetLightmapCoordinateIndex()	Get the UV channel that will be used for the lightmap	IDatasmithSceneElements.h
int32 GetLightmapSourceUV()	Get the source UV channel that will be used at import to generate the lightmap UVs	IDatasmithSceneElements.h
const TCHAR * GetMaterial ( int32 SlotId ) const	Get the name of the material mapped to slot Id, return nullptr if slot isn't mapped	IDatasmithSceneElements.h
TSharedPtr< const IDatasmithMaterialIDElement > GetMaterialSlotAt ( int32 Index ) const	Get the material mapping for slot Index	IDatasmithSceneElements.h

void SetFile ( const TCHAR* InFile )	Set the output filename, it can be absolute or relative to the scene file	IDatasmithSceneElements.h
void SetFileHash ( FMD5Hash Hash )	Set the MD5 hash of the current mesh file. This should be a hash of its content.	IDatasmithSceneElements.h
void SetLightmapCoordinateIndex ( int32 UVChannel )	Set the UV channel that will be used for the lightmap Note: If the lightmap coordinate index is something greater than -1 it will make the importer skip the lightmap generation	IDatasmithSceneElements.h
