Supported Blender versions

Blender version	Status	How it's verified
4.5 LTS (tested on 4.5.13 LTS)	Tested	Automated 40-case regression suite, plus packaging and extension-manifest checks. Last run 22 Sep 2026.
5.2 LTS (tested on 5.2.1 LTS)	Tested	Same automated suite; the .blend file (built under 4.5.13 LTS) opens and passes under 5.2.1 LTS. Last run 22 Sep 2026.
Blender 4.2 – 4.4, and other 4.5.x / 5.x releases	Installs, not tested	The add-on's manifest declares a minimum of Blender 4.2 (the first version with the extension system), so Blender will install it. No test pass has been run on these versions.
Earlier than 4.2	Not supported	No extension system to install the add-on into. The node group on its own (Append/Link, without the add-on) has not been tested on these versions either.

What this covers

ExploCallout ships two components:

• The add-on (explocallout-1.0.0.zip) — a Blender extension (GPL-3.0-or-later) that requires Blender's extension system, available from Blender 4.2 onward.
• explocallout.blend — the TO_Callouts Geometry Nodes node group, its bundled example scene, and the asset catalog file. This works with Append/Link/Asset Library on its own, with or without the add-on installed.

The add-on is optional but recommended — see the User Guide for the difference between the two ways of using the package.

Format and rendering

• Format: Blender extension (add-on) + native .blend asset (Geometry Nodes node group, cataloged for the Asset Browser) + example scene.
• Renderer: works with EEVEE, Cycles and Workbench — the callouts are geometry and text objects, not engine-specific effects.
