Copy Nodes Keyframes is an add-on designed to preserve animation data and driver connections when duplicating or copying nodes in the node editor. By default, Blender requires manual replication of keyframes and manual updating of driver variable paths when duplicating nodes. This tool automates the process, allowing multiple selected nodes to be duplicated simultaneously while retaining all associated keyframes, drivers, and links. The add-on automatically corrects driver paths inside node groups to prevent broken setups. It includes custom hotkeys for standard duplication, linked duplication, copying, and pasting across different node trees. Users can configure these shortcuts directly from the sidebar panel, which also provides access to detailed information about the selected nodes and an option to replace the last link upon duplication.
