IDatasmithMeshElement

[IDatasmithMeshElement](API\Runtime\DatasmithCore\IDatasmithMeshElement) defines an actual geometry.

Inheritance Hierarchy

ISceneGraphNode

IDatasmithElement

References

Module	DatasmithCore
Header	/Engine/Source/Runtime/Datasmith/DatasmithCore/Public/IDatasmithSceneElements.h
Include	#include "IDatasmithSceneElements.h"

Syntax

class IDatasmithMeshElement : public IDatasmithElement

Remarks

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.

	~IDatasmithMeshElement()

Functions

	Name	Description
float	GetArea()	Get the total surface area
float	GetDepth()	Get the bounding box depth
FVector3f	GetDimensions()	Get the bounding box dimension of the mesh, in a vector in the form of (Width, Height, Depth )
const TCHAR ...	GetFile()	Get the output filename, it can be absolute or relative to the scene file
FMD5Hash	GetFileHash()	Return a MD5 hash of the content of the Mesh Element.
float	GetHeight()	Get the bounding box height
int32	GetLightmapCoordinateIndex()	Get the UV channel that will be used for the lightmap
int32	GetLightmapSourceUV()	Get the source UV channel that will be used at import to generate the lightmap UVs
int32	GetLODCount()	Get number of LODs
const TCHAR ...	GetMaterial ( int32 SlotId )	Get the name of the material mapped to slot Id, return nullptr if slot isn't mapped
TSharedPtr< ...	GetMaterialSlotAt ( int32 Index )	Get the material mapping for slot Index
TSharedPtr< ...	GetMaterialSlotAt ( int32 Index )
int32	GetMaterialSlotCount()	Get the number of material slot set on this mesh
float	GetWidth()	Get the bounding box width
void	SetDimensions ( float InArea, float InWidth, float InHeight, float InDepth )	Set surface area and bounding box dimensions to be used on lightmap size calculation.
void	SetFile ( const TCHAR* InFile )	Set the output filename, it can be absolute or relative to the scene file
void	SetFileHash ( FMD5Hash Hash )	Set the MD5 hash of the current mesh file. This should be a hash of its content.
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
void	SetLightmapSourceUV ( int32 UVChannel )	Set the source UV channel that will be used at import to generate the lightmap UVs
void	SetLODCount ( int32 Count )	Set number of LODs
void	SetMaterial ( const TCHAR* MaterialPathName, int32 SlotId )	Set the material slot Id to use the material MaterialPathName
