In this tutorial I will show you how you can change a Blueprint Editor Billboard to any image you like!
This technique is widely applicable to all blueprints, even ones that have no default Editor Billboard.
Software used (in order):
Abobe Photoshop (not shown in video, used to edit the cat images)
Unreal Engine 5
If you have any questions/suggestions, feel free to ask them in the comments! I am always open to constructive feedback.
