I am having a problem with accessing child “Hands” of FirstPerson from my model BP.
Some time ago I was getting error “access none trying to read property” but not now.
I just think that It cant somehow access children components but dont know how to force it to do that.
Any solutions to my primitive BP?
P.S: Im novice in UE 
If you just want to access your Hands you don´t need the Branch. If you get access none errors it simply means the “Hands” variable refferences nothing (it was never assigned)
If you want to check if you specificly overlaped the Hands of the TPS Character keep it as is just use the “Other Comp” (the Component of the other) instead of Overlapping Component (your Component)
