set correctly the vr tracer blockset

I have 6dof robotic arm I want to trace the trajectory of end effector I simulate all of my system wìth simulink and 3d animation tollboxes I work whit R2012a. I try to use vrtracer block set but the result is not good. I have this vrml hierarchy :

DEF "nodetotracer" Transform
  children
    .... 
Group
  children
      DEF node1 transform
          children
              DEF node2 Transform 
                children
                     ......
                        .......

I want to tracer the movement of the "nodetotracer" but I have no error whit the vrtracer but I dont have the trajectory in the scene, all possible part are set correctly except for the parent node i think, becouse I used the same vr tracer blockset whit another simple vrml scene whitout to set node parent and run very well. Anyone have a suggestion for to help me? thanks
