Sorry I am having a little bit of trouble understanding what are you mean. Are suggesting that I use a hidden scene component as a collision mesh or some way of determining the location of the impact?
I am using mostly hitscan weapons like railguns, particle cannon, ect as anti tank weapons. It would probably be very inconsistent if I attempted to make it work for radial damage so I am thinking of just having explosions do a constant but low amount of damage to heavily armored vehicles.
