Syntax
UCLASS ()
class UBaseMeshFromSplinesTool :
public UInteractiveTool ,
public IInteractiveToolEditorGizmoAPI ,
public UE::Geometry::IDynamicMeshOperatorFactory
Remarks
Tool to create a mesh from a set of selected Spline Components
Variables
| Type | Name | Description | |
|---|---|---|---|
  |
TArray< TWeakObjectPtr< AActor > > | ActorsWithSplines | Note: We track actors instead of the USplineComponents here because the USplineComponents objects are often deleted / swapped for identical but new objects. |
 |
bool | bLostInputSpline | If failed to reacquire once, used to avoid trying to reaquire again. |
 |
TArray< FTransform > | LastSplineTransforms | Track the spline component's transform (to world space) |
 |
TArray< uint32 > | LastSplineVersions | Track the spline 'Version' integer, which is incremented when splines are changed. |
  |
TObjectPtr< UNewMeshMaterialProperties > | MaterialProperties | |
  |
TObjectPtr< UCreateMeshObjectTypeProperties > | OutputTypeProperties | |
  |
TObjectPtr< UMeshOpPreviewWithBackgroundCompute > | Preview | |
  |
TWeakObjectPtr< UWorld > | TargetWorld |
