Set Physical Material node in BP do not work with Destructibles

Using the Set Physical Material for Destructible does not work currently. In comparison with a static mesh physical material will change via key press during gameplay.

1. Open UE4
2. Create a DM and place in scene
3. Setup a material and a physical Material
4. Open the Level BP
5. Get a reference to the DM
6. Via key press set the material as the one just created
7. PIE
8. Press assigned key

Results: when assigning a material or physical material during game play there is no change in material or physical material when comparing this with a static mesh which is updated during the game.

Expected: When setting a material or physical material to a destructible during the game it will assign the new materials.
