Problem with GFxMinimap (2DMapTexture) [+HUD flaw :D]

[emadpres]

I'm trying to make my custom Hud(+minimap)
main trouble is "Minimap" !

According to Scaleform tutorials about HUD (Mastering a GFx HUD (Part 1-4) ) ,I made my three classes :
>GFXHudWrapper [extend HUD] : Handle HUD + Inventory + ...
>GFxHud [extend GFxMoviePlayer]: Handling and updating HUD's itesm+ Initialing and updating Minimap
>GFxMinimap [extend GFxObject] : Minimap Logic

First "GFxHudWrapper.uc" create a "GFxHud" .
Then "GFxHud.uc" load "Hud.swf" .
"Hud.swf" load "minimap.swf" internally, at the beginning with action-script :

var minimapContainer:MovieClip = this.createEmptyMovieClip("minimapContainer", this.getNextHighestDepth());
minimapContainer._x = 970;
minimapContainer._y = 8;
minimapContainer.loadMovie("minimap.swf");

In minimap.swf , I call "registerHUDMinimap" unrealscript function ,to initial "minimap GFxObject" in "GFxHud.uc" :

ExternalInterface.call("registerHUDMinimap", this);

"registerHUDMinimap" is a function in GfXHud.uc that Init my Minimap :

function registerHUDMinimap(GFxMinimap mp )
{
	//`log("Initiing MINIMAP !!!!--!!!!! ");
	Minimap = mp ;
	Radius = 10; //?
	CurZoomf = 64;
	NormalZoomf = 64;

	Minimap.Init(self); // <---- *

	Minimap.SetFloat("_xscale", 85);
	Minimap.SetFloat("_yscale", 85);
}

Initialization process for Minimap ...
[GFxMinimap.uc]

var UTMapInfo		MapInfo;
...
function Init(GFxHud h)
{
...
if (MapInfo.MapTexture != none)
	{
		MapTexSize = Texture2D(MapInfo.MapTexture).SizeX;
		SetString("mapImagePath", "img://" $ PathName(MapInfo.MapTexture));  <---------------- ****
	}
...
}

And the problem ...
I wonder how minimap 2DTexure is set in above code ?!??!
I use "VCTF-Necropolis.uk" map , that really has a minimap with a map-texture ! But when I play it with my GameCode (not UTGame) , nothing show in minimap except enemy+.. item as a red point !

PS: I can show my enemy+flag+... in minimap without problem ! I just have problem with 2D-map-texture showing .
PS: I knew editor method to change minimap texture ( Editor::WorldProperties->WorldInfo->MyMapInfo-> ... )

Thanks is advance for your helps
