Procedural meshes copying static meshes do not support UV hit results

Procedural meshes copying static meshes do not support UV hit results

Developer Notes

By Design. The logic in TraceUVTest (level Blueprint) is set to only trace WorldStatic, so the trace goes right through the barrel. If you change the Level BP to also add PhysicsBody then the trace does hit the barrel and shows a valid UV
