I have a new question 
How can I make the crosshairs more accurate? Let me describe a little and maybe you can point me in the right direction - I created a Desk, the drawers of the desk are usable items, when you use them they open and close - pretty simple… but when the drawers are closed the area to click on them is very small and is not the whole face of the drawer (as you’d expect) - so where can I look to make that system work across the entire mesh of the object?
Thanks!
False alarm! I figured it out - in the “GetUsableActor” in the “InventoryPlayerController” I set the “Trace Complex” of the “LineTraceForObjects” to true and that gives me exactly what I want!
