BoxTraceForObject

Hi,
i’m trying to animate hand with motion controller.
I’m using the node “BoxTraceForObjects” to get collision between hand and wall to be able to do Penetration BackTracking.
Unlike Unity I noticed that the box trace don’t get 4 contact points but only one.
The problem is that this contact point (in a few frames) change than a few centimeters even if the hand remains still.
My idea is that box trace returns only one point without a logical.
Has anyone ever used this node?
It’s possible to have all contact points?
