- UPersistentMeshSelection is largely a port of UGroupTopologyStorableSelection, with the actual selection data moved to FGenericMeshSelection - UPersistentMeshSelectionManager is meant to be used as a ContextObject in a ToolsContext, also contains utility functions to register/unregister/find context object - Selection is no longer passed as part of FToolBuilderState. Instead Tools access the selection via ContextObject - UPersistentMeshSelectionManager currently supports a single active selection. Selection changes are transacted via an FChange. - When not inside a Tool, Selection is visualized with a pink border outline. Currently vertex selection is not visualized. - Usage model is that on Tool Accept/Complete, prior to Tool Shutdown, any existing selection is cleared, and Tool may set a new Output selection which becomes the active selection - StoredMeshSelectionUtil.h has utility functions to get current selection, set output selection, and clear it - SingleSelectionMeshEditingTool already made input selection available to subclasses, port that capability to new architecture - convert EditMeshPolygonsTool to be a SingleSelectionMeshEditingTool, use provided Input selection and set Output selection as appropriate - ModelingToolsEditorMode clears active selection where appropriate, eg if selected object changes. However the behavior here will need further improvement, currently relies on questionable event handling from the TypedElement system #rb semion.piskarev #rnx #jira none #preflight 6136cbbfd9c85a0001fc3b56 #ROBOMERGE-AUTHOR: ryan.schmidt #ROBOMERGE-SOURCE: CL 17441056 in //UE5/Main/... #ROBOMERGE-BOT: STARSHIP (Main -> Release-Engine-Test) (v870-17433530) [CL 17441061 by ryan schmidt in ue5-release-engine-test branch]
