UI Animation Render is a Blender add-on for rendering animations of the Blender UI. Originally written by Luca Rood, it was part of the bundled add-ons shipped with Blender 4.1. It's now available as a standalone extension, offered as it is with limited support.
You reach the add-on from the View3D sidebar under the View tab, or trigger it with the Ctrl+Shift+F12 shortcut. It runs on Blender 4.2 LTS and newer, requires no special permissions, and is released under the GNU General Public License v2.0 or later.
Listed at version 0.1.0 and published in May 2024, UI Animation Render sits in the Blender extensions library among other community add-ons. For the latest details, installation options, and version history, check the developer's page.
