About Simple Renaming

Simple Renaming is a batch‑renaming addon for Blender that works with objects, materials, collections, Node Groups, Point Clouds and additional data types. It can replace names, add prefixes or suffixes, trim characters, and apply sequential numbering to all items or only selected ones, with optional filtering by type (e.g., meshes, cameras). The addon provides one‑click case transformations (UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase), regular‑expression search and replace (including case modifiers), and @‑variables that insert dynamic values such as object name, parent, collection, counters, blend file name, date, time and user‑defined slots. Version 2.1.8 removes the Sort by Selection feature for stability, fixes Grease Pencil v3 compatibility for Blender 4.3+, restores F‑curve handling for Blender 4.2–4.x, and uses O(1) lookups for faster renaming in large scenes. The addon is listed as free on the Blender Extensions platform.

Features

• Batch rename objects, materials, collections, Node Groups, Point Clouds, and more, applied to all items or only selected ones
• One-click case transformations to UPPERCASE, lowercase, Title Case, Sentence case, camelCase, or PascalCase
• Search and replace with Regular Expression support, including regex case modifiers (\U, \L, \E)
• @-variables insert dynamic values into name patterns — object name, parent, collection, sequential counters, filename, date, time, and user-defined slots
• Sync object names with their data, plus Also Rename Data to rename linked data-blocks (mesh, curve, light) to match
• UV map renaming by index, active UV set, or batch across multiple objects
• Custom hotkeys and clear feedback showing exactly what was renamed

Best for

Blender users who need to rename large numbers of objects, materials, UV maps, Node Groups or other data blocks quickly and consistently.
