Adding Dynamic Variable to customMaterials

HI
I make this resource(www.torquepowered.com/community/resources/view/15211) modification to t3d.


This is what I did.

script

singleton ShaderData( ambientShader )
{   
	DXVertexShaderFile 	= "shaders/common/ambientV.hlsl";   
	DXPixelShaderFile 	= "shaders/common/ambientP.hlsl";   
	
	pixVersion = 2.0;
};


singleton CustomMaterial(testMaterial) // v1.1
{

  shader = OutLineShader; 
  stateBlock = ambientShader;
  
  testColor = 0.5f;  //This is Dynamic Variable
  
  version = 2.0;

};

Shader

//Vertex Shader

#define IN_HLSL
#include "shdrConsts.h"

uniform float4x4 modelview : register(VC_WORLD_PROJ);
uniform float testColor ; //this variable is problem. 
                          //Script Controlled Variables is not working... 


struct VS_OUTPUT
{
    float4 Pos			: POSITION;
    float4 Color		: COLOR0;

};


VS_OUTPUT main( float4 Pos : POSITION ,float3 Normal : NORMAL )
{
	VS_OUTPUT Out = (VS_OUTPUT)0;

	Out.Pos = mul(modelview,Pos);
	Out.Color = float4(testColor,testColor,0.0f,1.0f); //Script Controlled Variables is not working... 
	return Out;
}



//Pixel Shader 

#define IN_HLSL
#include "shdrConsts.h"


struct PS_INPUT
{
    float4 Color		: COLOR0;
};

float4 main(PS_INPUT Input) : COLOR
{   
   float4 color;
   color = Input.Color;
   return color ;
}

engine change
