struct FCreateMeshObjectParams

Remarks

FCreateMeshObjectParams is a collection of input data intended to be passed to UModelingObjectsCreationAPI::CreateMeshObject(). Not all data necessarily needs to be specified, this will depend on the particular implementation. The comments below are representative of how this data structure is used in the Tools and API implementation(s) provided with Unreal Engine, but end-user implementors could abuse these fields as necessary.

The definition of a "mesh object" is implementation-specific.

Variables

Type	Name	Description
TArray< TObjectPtr< UMaterialInterface > >	AssetMaterials	Optional Materials for a newly-created Mesh Asset, if this is applicable for the created mesh object
FString	BaseName	The base name of the new mesh object
bool	bEnableCollision	Collision settings, if applicable for the given mesh objectSpecify whether the new mesh object should have collision support/data
bool	bEnableNanite	Specify whether Nanite should be enabled on this new mesh object
bool	bEnableRaytracingSupport	Rendering Configuration Options, if this is applicable for the given mesh objectSpecify whether normals should be automatically recomputed for this new mesh object
bool	bEnableRecomputeNormals	Mesh Build Options, if this is applicable for the given mesh object (Currently somewhat specific to Assets in the Editor)Specify whether normals should be automatically recomputed for this new mesh object
bool	bEnableRecomputeTangents	Specify whether tangents should be automatically recomputed for this new mesh object
bool	bGenerateLightmapUVs	Specify whether to auto-generate Lightmap UVs (if applicable for the output mesh type)
TEnumAsByte< enum ECollisionTraceFlag >	CollisionMode	Which Collision mode to enable on the new mesh object, if supported

TArray< TObjectPtr< UMaterialInterface > >	Materials	Materials settingsMaterials for the new mesh object
TOptional< FMeshDescription >	MeshDescription
ECreateMeshObjectSourceMeshType	MeshType	The Mesh Object should be created based on the mesh data structures below.
FMeshNaniteSettings	NaniteSettings	Specify the Nanite Settings for this new mesh object, only used if bEnableNanite=true
TObjectPtr< UPrimitiveComponent >	SourceComponent	Base dataA Source Component the new mesh is based on, if such a Component exists
TObjectPtr< UWorld >	TargetWorld	The World/Level the new mesh object should be created in (if known)
FTransform	Transform	The 3D local-to-world transform for the new mesh object
ECreateObjectTypeHint	TypeHint	A suggested type for the newly-created Mesh (possibly ignored)
TObjectPtr< UClass >	TypeHintClass	A suggested UClass type for the newly-created Object (possibly ignored)
