The Houdini Geometry Renamer Tool is a Qt-based UI application that helps artists manage and rename geometry nodes within a Houdini scene. It scans the current scene to identify geometry nodes and lists them for selection. Users can view and select child nodes and rename them with automated suffixes based on node type. The tool allows flexible renaming, either individually or collectively, enhancing file organization and project workflow consistency. It also includes customization for suffixes through a global dictionary, making it adaptable to different naming conventions.
