Functions

  Type Name Description
Public function void

AppendAppliedHighlight ( const TArray< FUVToolSelection >& AppliedSelections,
bool bUsePreviews
)

 Adds additional highlighting elements based on selection information.
Public function FTransform Get the current transform of the unwrap highlight.
Public function void

Initialize ( UWorld* UnwrapWorld,
UWorld* LivePreviewWorld
)

  
Public function void

RebuildAppliedHighlightFromUnwrapSelection ( const TArray< FUVToolSelection >& UnwrapSelections,
bool bUsePreviews
)

 Convert the unwrap selections to elements in the applied mesh, then highlight those there.
Public function void

RebuildUnwrapHighlight ( const TArray< FUVToolSelection >& Selections,
const FTransform& StartTransform,
bool bUsePreviews
)

 Rebuilds the unwrap mesh highlights.
Public function void When true, edge selections also highlight the edge pairings (i.e. edges that could weld with the selected edges).
Public function void

SetIsVisible ( bool bUnwrapHighlightVisible,
bool bLivePreviewHighlightVisible
)

  
Public function void

SetUnwrapHighlightTransform ( const FTransform& Transform,
bool bRebuildStaticPairedEdges,
bool bUsePreviews
)

 Set the transform of the unwrap mesh highlights without rebuilding them, likely to follow the translation of the underlying elements via gizmo.
