In official plug in,when you put LeapMotioncontroller actor into the unreal world but hand does not show up in the location you put the controller but some location far away.
I found the problem is in Engine/Runtime/LeapMotionController\Source\Private \ LeapMotionHandActor.cpp
at about line 153
PrimitiveComponent->SetRelativeLocationAndRotation(TargetPosition, TargetOrientation, true);
}
I changed it to:
PrimitiveComponent->SetWorldLocationAndRotation(TargetPosition, TargetOrientation, true)
Now Hand correctly appeared at he location you placed it
