Unbreakable chunks of the DestructibleMesh

Hi there, I’ve tested destructible mesh created from NVIDIA PhysX Lab, and there is a problem to fracture the destructible mesh which has more than 1 depth.

I’ve created destructible mesh asset using PhysXLab with the ‘Max Depth’ property as 2.

At the UE4, I’ve configured the destructible mesh like below.

After then, I shoot the weapon carefully to fracture only small parts.
They broken well, but some chunks which was not fractured more than depth 1 at the first shot, became unbreakable chunks.

I enabled ‘Simulate Physics’.
When I disabled physics, that ‘unbreakable chunk’ became not movable mesh like Static Mesh.

I would appreciate it if you could answer for this problem.

Try turning off your Asset Defined Support and World Support settings; since you are using Support Depth you should only need those two if you are trying to build something special with your DM. You should also check to make sure you didn’t turn that on any of that Chuck’s Parameters.

You could also be running into bug with the DM where you can only hit it with impact damage from a particular side of the mesh, in which case you will want to reduce the complexity of the mesh or turn off impact damage and use the blueprint system to apply damage and impulse.
