Render effect in a voxel software to UE

I’m using MagicaVoxel to create objects for Unreal. I found a render effect called Rounded Edges (RE). I really like it and I wanted to import it or recreate it in Unreal. I search on google so many things but it only give me a rounded corners effect. Look at the picture to see what I’m talking about. So I wonder if I can import it or I need to create it in UE4
