Hi PhilPix,
I don’t have any specific recommendations regarding that at the moment. I can add the notes though. Destruction in the engine still has a ways to go. While the majority of stuff is working there are still some known issues and areas that really need to some attention as well.
On our UE4 Trello Road map there will be a dedicated time of focus to get destructibles in a more suitable position. However, there isn’t a specific ETA for this due to other higher priority features at the moment.
