To create a Blender add-on with Python, you build a module that defines and registers custom operators, panels, and properties to extend Blender's functionality and automate workflows.

For Blender 3.0+ compatibility, your add-on needs a clear bl_info structure, Python classes for operators and panels, and rigorous registration and unregistration logic.

Registering and unregistering operators in Blender Python involves defining classes with specific bl_idname properties and calling register and unregister functions to safely load and unload the add-on.

You build UI panels for Blender add-ons by defining Python classes that inherit from bpy types, specifying the panel layout to expose controls directly in the 3D View and other editors.

The best way to package a Blender add-on for distribution is to organize your Python modules into a folder, include a proper bl_info structure, and compress it for easy installation.

If your Blender add-on is not showing up in Preferences, it is likely due to missing the bl_info structure or errors in the registration and unregistration logic of your Python classes.
