instantiate render layer

Hi

I'm instantiating copies of my balloon-prefab.
The original prefab is on top af the facemask (in yellow circle), but all copies of the balloon ends up behind the facemask. 

How do I fix this?


This is my hierarchy:

And I've used this code to spawn new instances (set on "balloons" <-- small "b"):

// -----JS CODE-----
// @input Asset.ObjectPrefab prefab

//get random position
function getRndInteger(min, max) {
   return Math.floor(Math.random() * (max - min) ) + min;
}

function spawn() {
   if(script.prefab) {
      var newObj = script.prefab.instantiate(script.getSceneObject());
      var x = getRndInteger(-15, 15);
      var y = -40;
      var z = getRndInteger(-13, -5);
      var newPos = new vec3(x, y, z);
      newObj.getTransform().setWorldPosition(newPos);
      return newObj;
   } else {
      return undefined;
   }
}

spawn();
