Line Trace only returns Physical Material data from the Element 0 material slot

Line Trace only returns Physical Material data from the Element 0 material slot of a skeletal mesh. All other material slots are ignored.

This is present on any skeletal mesh but is also reproducible on destructible meshes.

1. Open the attached test project
2. PIE
3. Left-mouse click to line trace from the camera
4. Fire the line trace multiple times at the Skeletal Mesh making sure to hit the white material and the blue material on the chest

Results: The Print String will always return PM_01, which is the physical material assigned to the white material, even with hitting the blue material (which is assigned PM_02).

Expected: For the line trace to return the correct physical material that is assigned to the hit material.

Ex: PM_01 when hitting the white material and PM_02 when hitting the blue material.

Destructible Meshes always return the first Materials PM
