Converting shaders to Torque format

I read somewhere awhile ago that you could drop in shaders from say RenderMonkey (or maybe DX9) and run them as-is in Torque. I'm having some problems understanding and getting these to work so maybe someone can shed some light on this.

I have this shader exported from a RenderMonkey sample (Plastic) in fx format:

//**************************************************************//
//  Effect File exported by RenderMonkey
//
//  - For this version, exporting to FX file is not perfect. 
//    There are many informations doesn't get exported. 
//    Currently, exporter does not try to resolve naming conflicts
//    ( functions, variables etc )
//    Please fix these issues before using this Effect file
//**************************************************************//
float4 view_position : CameraPosition = { -185.552780, -43.722942, -60.485661, 1.000000 };
float4x4 view_proj_matrix : ViewProjection;
//--------------------------------------------------------------//
// Plastic
//--------------------------------------------------------------//
float4 color = { 1.000000, 0.300752, 0.000000, 1.000000 };

//--------------------------------------------------------------//
// Single Pass
//--------------------------------------------------------------//
struct VS_OUTPUT {
   float4 Pos:     POSITION;
   float3 normal:  TEXCOORD0;
   float3 viewVec: TEXCOORD1;
};

//
// Vertex shader
//
VS_OUTPUT main(float4 Pos: POSITION, float3 normal: NORMAL){
   VS_OUTPUT Out;

   Out.Pos = mul(view_proj_matrix, Pos);

   // World-space lighting
   Out.normal = normal;
   Out.viewVec = view_position - Pos;

   return Out;
}

//
// Pixel shader
//
float4 main(float3 normal: TEXCOORD0, float3 viewVec: TEXCOORD1) : COLOR {
   // Simple lighting lighting model for a dull plastic appearance.
   float v = 0.5 * (1 + dot(normalize(viewVec), normal));

   return v * color;
}

So for things like view_proj_matrix and view_position variables, I passed them into the vertex shader like this:

VS_OUTPUT main(float4 Pos: POSITION, float3 normal: NORMAL,
    uniform float4x4 view_proj_matrix : register(VC_WORLD_PROJ),
    uniform float4x4 view_position : register(VC_EYE_POS)
)

(RenderMonkey has them registered as C0 and C4 but I didn't think VC_TEX_TRANS1 was right?)

There's also the color varible for the pixel shader that I passed in as register(C0) since that's what the ATI shader had it set as.

Anyways, it compiles with no errors but doesn't show up when I swap a material out for them (I replaced the OrcSkin mapping with my material).

What brain dead thing am I doing wrong here? I notice all the TSE shaders use their own conventions for names like the VS_OUTPUT but that's just names right? Or does it make a difference?
