Destructible mesh hollow inside

[CatsNipYummy]

I’ve been trying to create a destructible mesh from a FBX model. The model breaks apart well. But the mesh is not solid. Thus I get the below effect when I break a part of it. Do I need to make any specific changes to Unreal settings or the model itself? I do not want to see the inside of the model like below:

Hope the image explains my issue better. I want something like this:

Thanks.

Inside the Destruction mesh actor, you will find a setting that is: “Double sided” or “Double sided material” set that to true. If not, go to the material of that actor and do the same. “Double sided material”
