How can I put a custom object into the scene 'by default'?

Hi all,

First off, if similar questions have been asked, my apologies. and could you give me a pointer to the article(s) in that case. I have searched the community but no luck.

I'd like to to add a custom C++ object, which is fxRenderObject by Melv May, into the scene when the mission is launched. In other words, the custom object should be in the scene, like a terrain, before the player spawns.

According to the Torque Scripting tutorial (http://www.garagegames.com/docs/tge/general/ch05s02.php,) it seems like I can add the object by writin a script (let's say blah.cs):

new fxRenderObject()
{
    position = "23.0, -410.0, 200.0";
};
echo("fxRenderObject is called."); // just for debugging

And I made TGE call this blah.cs from game.cs:

function onServerCreated() // or function onMissionLoaded()
{
    // snip...
    exec("./blah.cs");
}

However, nothing appears in the scene. nor in the world editor inspector. I got a debugging message in the console though. Am I doing something completely stupid here or missing something important?
any suggestions are appreciated.

thanks,
So
