Hi Zuaxis,
You can right click on any Static Mesh asset in the content browser and there is an option near the top that says “Create Destructible Mesh”. That will create the destructible version for you. After it is created, open it up and press the “Fracture Mesh” button to generate the fracture pieces and then save that asset.
Now you can use it in the world or in a blueprint to have destruction everywhere!
Cheers,
