Creating add-ons for Blender

Learn to write Blender add-ons with this fast paced, information dense primer. Now updated for Blender 2.93 (and works with 2.92 as well).

A practical primer

This primer on writing Blender add-ons aims to be short an sweet and pretty fast paced. This means that we cover quite a lot of concepts in a short time but I have provided links to additional information where relevant.
You also need to have some experience in writing Python programs but other than that you will find that writing Blender add-ons is surprisingly simple. Almost anything is possible due to the large amount of built-in functionality available from within Python and this huge collection of classes and functions might be a little bewildering to navigate but the basics of a Blender add-on are easy to grasp in just a few hours.

In this primer you will start with an almost trivial add-on and work your way to a full fledged add-on that manipulates meshes and is fully integrated with Blender's own graphical user interface, complete with user configurable properties and custom icons.

Multiple formats

Formatting books with program listings is always a challenge but the .zip file that you can download when purchasing this e-book contains an .epub version of the book (readable by most e-readers), a .mobi version (readable by most Kindles) and a .pdf version.

Also, the source code accompanying the book is available on GitHub.
