Using Terrain From Terrain Editor

I’m trying out the terrain builder in JME3.1 and I built just a basic flat terrain accepting the defaults along the way. I added light so it can be seen and then I added static rigid body by right clicking on the terrain going to “Add Control” and click on Static RigidBody. I thehn try to load it in code like this:

rootNode.attachChild(assetManager.loadModel("Scenes/newScene.j3o"));

I’m not adding any light in code because I already added light in the terrain editor. But when I do this and click run I can’t see the terrain anywhere. I also tried adding light pragmatically as well but that doesn’t seem to have any affect. I’m just wondering if I am missing something. How can I create a terrain and load it in game so I can run around on it?
