Data-Block Utilities earns its place in the Blender extensions library for gathering data-block inspection and duplicate merging into a single Scene Overview panel.
Data-Block Utilities is a Blender add-on that runs from Properties ‣ Scene Overview. It shows data-block users in a filterable tree layout, and clicking any data-block jumps to where it's used.
The add-on merges duplicate node groups, materials, images, meshes, and lights, and shows node trees scored by their similarity. Version 1.3.2 corrects how Find Similar and Duplicates handle overridden data-blocks and fixes lights being incorrectly listed as duplicates in Blender 5.1 onwards.
It's compatible with Blender 4.2 LTS and newer, written entirely in Python, and released under the GNU General Public License v3.0 or later, requiring no special permissions. The extension can be added by dragging it into Blender or installed from disk, with a download size of around 1.7 MB.
Data-Block Utilities is best for blender users tracing where data-blocks are used and merging duplicate materials, meshes, node groups and other data-blocks.
Data-Block Utilities is completely free to download and use.
Data-Block Utilities is compatible with Blender 4.2 LTS and newer, so current LTS builds and later releases are covered. The add-on is written entirely in Python and requires no special permissions to run. Version 1.3.2 includes fixes affecting Find Similar and Duplicates, including corrected handling of overridden data-blocks and a fix for lights being incorrectly listed as duplicates in Blender 5.1 onwards.

Data-Block Utilities lives under Properties ‣ Scene Overview once installed. From there it shows data-block users in a filterable tree layout, and clicking any data-block jumps to where it's used. The panel also handles merging duplicate node groups, materials, images, meshes and lights, plus showing node trees scored by their similarity. If the panel isn't visible, confirm the add-on is enabled in Blender's preferences.
Data-Block Utilities can be added by dragging and dropping the extension into Blender, or by downloading the file and using Install from Disk in Blender's preferences. The download is around 1.7 MB. After installation, enable the add-on and open Properties ‣ Scene Overview to use it. Version 1.3.2 is the current release listed here, and the developer's page on GitHub carries the source and download link.
Data-Block Utilities is released under the GNU General Public License v3.0 or later. It's listed as free in this catalog and requires no special permissions in Blender.
