[JAVA3D] VRML scene problems

[David]

Hi all:   I have been trying to load a VRML into my scene.  It loads and attaches but I can't see anything.  Any suggestions?   Loading code:      System.out.println("Loading terrain map");    String URLname = "c:/GameDev/world.wrl";      try {   Scene scene = modelLoader.load(URLname);   if (scene != null) {          BranchGroup  bg = scene.getSceneGroup();    tg.addChild(bg);          System.out.print(bg.toString());   } else {      System.out.println("Scene failed to load.");         }  } catch (FileNotFoundException fnfe) {   System.out.println(URLname + " URL not found.");   System.out.println("Please try again.");  } catch (Exception e) {   System.out.println("Exception loading terrain : "+e.getMessage());    }         tg.compile();  u.addBranchGraph(tg);       Here is the header for the file:        Group {  children  [   NavigationInfo { type [ "EXAMINE", "ANY" ] }   Transform   {    translation -31.50 0 -31.50 # Center heightfield on origin    children    [     Shape     {      appearance Appearance      {       material Material { diffuseColor 0.700 0.700 0.700 }      }      geometry ElevationGrid      {       xDimension 64       xSpacing 1.0000       zDimension 64       zSpacing 1.0000       solid FALSE       creaseAngle 3       height       [ 3.225 3.225 3.225 3.225 3.225 3.225 3.2 3.2 3.2 3.175 3.15 3.15 3.124 3.099 3.099 3.074
