Syntax
class FBasicDynamicMeshSelectionTransformer : public IGeometrySelectionTransformer
Remarks
BasicDynamicMeshSelectionTransformer is a basic Transformer implementation that can be used with a FBaseDynamicMeshSelector. This Transformer moves the selected vertices and nothing else (ie no polygroup-based soft deformation)
