I was trying to do the Behavior Tree Quick Start Guide in the UE 4.13 version and found out my Multi Sphere Trace hits nothing.

After looking for the usual problems people talk in the forums and answerhub, I could not find a answer.
Debugging seems that the Multi Sphere returns nothing:

  • I tried to remove the actors to
    ignore,
  • Changed the player
    (topdowncharacter) collision
    definition from CharacterMesh to Pawn
    and custom.
  • Add a Default Pawn in the
    radius. (That ball)
  • Put everything I could in the
    Object Type Array.
  • Change the Tick to AI
  • Force a matrix instead using the variable.

The only thing that update in the Blackboard is the HomeLocation (Follower Actor position, and center of the Multi Sphere Trace)

Debug - Peão = Pawn

Player

Follower

By now it is rather uncommon to use Multi Sphere to detect other Characters, just google Pawn Sensing.
I know this is not the answer your looking for but maybe a this will help you out.

Thank you for your advice Speckulous, searching for Pawn Sensing I could find about AI Perception. UAIPerceptionComponent | Unreal Engine Documentation
But still, I wish to find out why the Multi Sphere finds nothing I put in its range, not only pawns.

Found out that I need to set another value to the END
