More terrain madness

I have found that you can easily add a terrain created with L3DT in the txscene:

<Terrain type="GarageGames.Torque.T3D.XTerrain" name="Terrain">
      <Position>
        <X>0</X>
        <Y>0</Y>
        <Z>0</Z>
      </Position>
      <HorizontalScale>8</HorizontalScale>
      <VerticalScale>1</VerticalScale>
      <Scale>
        <X>8</X>
        <Y>8</Y>
        <Z>1</Z>
      </Scale>
      <Repeat>true</Repeat>
      <RepeatX>true</RepeatX>
      <RepeatY>true</RepeatY>
      <Data type="GarageGames.Torque.T3D.RAWTerrainData">
        <TerrainFilename>dataterrainsnew_terrain.raw</TerrainFilename>
        <LightMapFilename>dataterrainsnew_terrain_LM.jpg</LightMapFilename>
        <TexturePathSubstitution>dataterrains</TexturePathSubstitution>
				<UniqueTextureFilename>dataterrainsnew_terrain_TX.jpg</UniqueTextureFilename>
      </Data>
      <ViewError>2</ViewError>
      <LODError>0.5</LODError>
      <LevelZeroError>0</LevelZeroError>
    </Terrain>

OK coolness it works pretty good. So I open the Torque X 3D Builder, and it will not open. As a matter of fact if I go and edit the scene level data it even changes the names from new_terrain to terrain and loads some default raw terrain.

At this point this is useless. How can I create a terrain and add my objects players etc to my terrain when the 3D scene builder doesn't work with any terrain except the built in defaults? This is really not cool. I guess I can write tons of code, get out pencil and paper and calculate all the coordinates etc, but then why did I pay for this?

I tried importing the terrains into the 3D editor but they don't show up. If I replace the .ter file with a TGE terrain it shows up in the editor. I have not tried making a second level with another TGE terrain yet but I am pretty certain it will not work at this point.
