Destructible mesh on mobile

I’m trying to create a destructible mesh on mobile. I know, APEX isn’t supported on mobile yet, so I tried his workflow:

But I’m wondering how to import a chunked mesh like he said. When I hit “combine mesh”, I’ve only one single Mesh, which will not act like many chunks. When I don’t use it, I’ve 20 meshes, which I can’t use in Blueprint scripting…
I hope you have an idea on how to simulate destructible meshes on a mobile device!

Thank you very much and best regards from Germany.
