Simple Renaming is an addon that provides batch renaming capabilities for objects, materials, collections, and data blocks in Blender. It allows users to modify names across multiple assets simultaneously using features like search and replace, sequential numbering, and the addition of prefixes or suffixes. A key feature is the ability to sync object names directly with their underlying data blocks, maintaining consistency in the Outliner.

Users can filter renaming operations by specific data types, such as meshes or cameras, and apply changes to either the active selection or the entire scene. The tool also supports advanced renaming tasks through Regular Expressions (Regex) and sorting operations based on selection order or 3D position.
