UPatternTool

[UPatternTool](API\Plugins\MeshModelingToolsExp\UPatternTool) takes input meshes and generates 3D Patterns of those meshes, by placing repeated copies along geometric paths like lines, grids, circles, etc.

Syntax

UCLASS ()  
class UPatternTool : public UMultiSelectionMeshEditingTool

Remarks

UPatternTool takes input meshes and generates 3D Patterns of those meshes, by placing repeated copies along geometric paths like lines, grids, circles, etc. The output can be a single Actor per pattern Element, or combined into single Actors in various ways depending on the input mesh type.

Variables

Protected variable UProperty TSet< TObjectPtr< UPrimitiveComponent > > AllComponents  
Protected variable TArray< const UPrimitiveComponent * > AllPreviewComponents This duplicates the data stored by PreviewComponents but it is necessary to have a simple TArray of all preview components when raycasting, otherwise the raycasts will hit the preview components from the previous frame.
