When importing destrucitble APB asset files from PhysX Labs there is no visible shadow cast for these meshes. The same is not true for a destructible created in UE4. These are using the default settings for the lights, with exception of possibly changing to dynamic only.

I tested this back to 4.0 and noticed the same behavior there as well.

Attached: image for comparison and PXL created asset.

Steps to Reproduce

1. Create a basic fracture asset in PhysX Labs or use the attached example
2. Open UE4
3. Import PXL asset
4. Place in scene with stationary or dynamic lighting

Expected: The imported asset from PXL will cast a shadow with default settings.

Results: Imported APB assets from PXL do not cast a shadow. When compared to a fracture mesh generated (using the same settings as PXL) will result in different results. The fracture mesh in UE4 will cast a shadow.
