Blender 2.8 Python Set Active Object

In Blender, the active object refers to the selected object that is currently being edited or manipulated. In this guide, we will learn how to set the active object using Python scripting in Blender 2.8.

Prerequisites

• Blender 2.8 or above
• Basic knowledge of Python programming language

Setting the Active Object

To set the active object in Blender using Python, you need to access the context object and modify its active_object property. Here's an example code snippet:

import bpy

# Get the active object
active_object = bpy.context.active_object

# Set a new active object
new_active_object = bpy.data.objects['Cube']
bpy.context.view_layer.objects.active = new_active_object

# Print the new active object name
print("New Active Object:", new_active_object.name)

In the above code, we import the bpy module (Blender Python API) and access the active_object property of the context object to obtain the current active object.

To set a new active object, we retrieve the desired object from the bpy.data.objects collection and assign it to the active property of bpy.context.view_layer.objects. Finally, we print the name of the new active object.

Make sure to replace 'Cube' in the code example with the name of the object you want to set as the active object.

Conclusion

With Python scripting in Blender 2.8, you can easily manipulate and set the active object. This allows you to automate tasks and manipulate objects programmatically. Understanding how to set the active object is essential when developing add-ons or creating complex workflows in Blender.
