Python is an interpreted, interactive, object-oriented programming language. It incorporates modules, exceptions, dynamic typing, very high-level dynamic data types, and classes. Python combines remarkable power with very clear syntax.
Python scripts are a versatile way to extend Blender functionality. Most areas of Blender can be scripted, including animation, rendering, import and export, object creation and automating repetitive tasks.
To interact with Blender, scripts can make use of the tightly integrated API.
Links that are useful while writing scripts:
Python.org – General information about Python.
Blender Python API – Official API documentation. Use this for referencing while writing scripts.
API Introduction – A short introduction to get you started with the API. Contains examples.
Links that deal with distributing your scripts:
The following links take you from the basics to the more advanced concepts of Python scripting for Blender.
Here are external links containing a lot of good information to start learning how to write scripts for Blender:
Add-ons are scripts that enable Blender to gain extra functionality, they can be enabled from the Preferences.
Outside of the Blender executable, there are hundreds of add-ons written by many people:
Officially supported add-ons are bundled with Blender.
Other Testing add-ons are included in development builds of Blender but not official releases. Many of them work reliably and are very useful but are not yet ensured to be stable for release.
See Add-ons for documentation on add-ons included with Blender.
Apart from add-ons, there are several other types of scripts that extend Blender’s functionality:
Utility libraries for import into other scripts.
Settings for Blender’s tools and key configurations.
These files are imported when starting Blender. They define most of Blender’s UI, as well as some additional core operators.
- Custom Scripts
In contrast to add-ons they are typically intended for one-time execution via the Text Editor.
Saving your own Scripts¶
All scripts are loaded from the
scripts folder of
the local, system and user paths.
You can setup an additional search path for scripts in File Paths .
Add-ons are conveniently installed through Blender in the Preferences.
Click the button and select the
To manually install scripts or add-ons, place them in the
startup directory according to their type. See the description above.
You can also run scripts by loading them in the Text Editor.
