APEX destruction renders when using the Play > Mobile Preview.
1. Open UE4
2. Create Destructible Mesh
3. Set the Impact Damage to 1 and Impact Damage Depth to 0
4. Place in the scene above the ground
5. In the details panel set to Simulate Physics
6. Play > Mobile Preview
7. Watch the DM fracture
Results: In the Mobile Preview the destruction mesh will work and fracture.
Expected: APEX Destruction is unsupported on Mobile and should not work. I tested this with Cloth as well which does not move in the Mobile Preview.
