- New UInteractiveToolCameraFocusAPI UInterface defines functions a Tool can implement to publish its ability to provide a focus-box and focus-point - ModelingMode uses this API to customize behavior. Box-focus (f hotkey) will now always focus on Tool-provided focus-box if available. Point-focus (c hotkey) will focus on nearer of world-hit and Tool focus-point. - Default implementations for PrimitiveComponentToolTarget in SingleSelectionTool and MultiSelectionTool - Custom focus-box implementations for PolyEdit-derived and TriSelect-derived tools, to focus on active selection if available - Custom focus-point implementations for MeshSurfacePointTool #rnx #jira none [CL 16246252 by Ryan Schmidt in ue5-main branch]
