Creating Destructible with PhysXLabs and Fracture Tool in UE4 yield different results and same settings

When creating fracturing a mesh in PhysXLabs vs UE4 fracture tool with both using Voronoi fracture and set to 25 chunks will give different results.

The mesh (Attached below along with reference images) will fracture correctly and import correctly from PXL with the apb file generated. In UE4 the mesh will be a single chunk.

Any settings other than 1 for cell site count results in the same as the provided image.

By cleaning up extraneous geometry this can be avoided.

1. Open UE4
2. Import BunkBase.FBX (attached)
3. Create DM
4. Fracture the DM
5. See Results
