Plz help me, so that i can understand once and for all.

hmm, 3dgs provides matWorldViewProj; instead of MatrixWVP; and matWorldView; instead of matWorldView;

you need to set a lightdirection, too like vecSunDir; or vecLightDir[x];

your error is, that you just copied an fx-file like it was , without porting it to 3dgs style, plus your error is that you dont tell anything about what you want to achive and what errors you get in detail... thus making it hard to help

I putted the code there, like you said, the errors are everything inside the effect="...";

Can you explain simplyfied what you just said?

1) Change MatrixWV to matWorldView
2) Change MatrixWVP to matWorldViewProj
3) LightDirection isn't set, you'll have to define it. Most likely what you want to do is use the global sunlight, so put this at the top of the code:
Code:

---

extern float4 vecSunDir

---

And change LightDirection to vecSunDir in your code.

That should be it...

thnks to your help, most of the erros desapeared

but i'm a slow learn, and my engine is not so friend of myne, so it gives now another excuse to dont work...

I changed what you said:


----------------------------------
material Spec_ef
{
effect ="
extern float4 vecSunDir;
struct VS_OUT
{
float4 Position : POSITION;
float4 Diffuse : COLOR0;
float4 Specular : COLOR1;
float2 TexCoord : TEXCOORD;
};

struct VS_IN
{
float4 Position : POSITION;
float3 Normal : NORMAL;
float2 TexCoord : TEXCOORD;
};

VS_OUT main(VS_IN In)
{
VS_OUT ret;

// Transform model vertex position to
// screen space.
ret.Position = mul(In.Position, matWorldViewProj);

// Transform model vertex normal to view space
float3 ViewNormal = mul(In.Normal, (float3x3)matWorldView);
ret.Diffuse = max(0, dot(ViewNormal, LightDirection));

// Find Eye Vector by Normalizing view position
float3 ViewDir = normalize(mul((float3)In.Position, (float3x3)matWorldView));

// Calculate reflect vector
float3 ViewReflect = reflect(-ViewNormal, LightDirection);
ret.Specular = pow(max(0, dot(ViewReflect, ViewDir)), 4);

// Output texture coordinates to pixel shader
ret.TexCoord = In.TexCoord;

return ret;
}";
} <---------------------------this-last-line---------------


-----------------------------------------------

but now the engine says that there's an erros in the last line.
did i fail in something?
I thnik didnt catch the "extern float4 vecSunDir;" to well.



I have the 6.12 version of the engine, my browser dont let me update, it says "link is broken!". reinstalation dont fix it, and i dont want to format my pc so soon, if someone could send me the update.

effect="..."; - you missed the semicolon

looooool
ops...

but there's still a problem:




The code:

----------------------------------
material Spec_ef
{
effect ="
extern float4 vecSunDir
struct VS_OUT
{
float4 Position : POSITION;
float4 Diffuse : COLOR0;
float4 Specular : COLOR1;
float2 TexCoord : TEXCOORD;
};

struct VS_IN
{
float4 Position : POSITION;
float3 Normal : NORMAL;
float2 TexCoord : TEXCOORD;
};

VS_OUT main(VS_IN In)
{
VS_OUT ret;

// Transform model vertex position to
// screen space.
ret.Position = mul(In.Position, matWorldViewProj);

// Transform model vertex normal to view space
float3 ViewNormal = mul(In.Normal, (float3x3)matWorldView);
ret.Diffuse = max(0, dot(ViewNormal, LightDirection));

// Find Eye Vector by Normalizing view position
float3 ViewDir = normalize(mul((float3)In.Position, (float3x3)matWorldView));

// Calculate reflect vector
float3 ViewReflect = reflect(-ViewNormal, LightDirection);
ret.Specular = pow(max(0, dot(ViewReflect, ViewDir)), 4);

// Output texture coordinates to pixel shader
ret.TexCoord = In.TexCoord;

return ret;
}";
}
----------------------------------

3) LightDirection isn't set, you'll have to define it. Most likely what you want to do is use the global sunlight, so put this at the top of the code:
Code:

extern float4 vecSunDir


"And change LightDirection to vecSunDir in your code." ----> how do i do that?

example:
ret.Diffuse = max(0, dot(ViewNormal, vecSunDir)); //it may be that you need to use -vecSunDir

Actually... it's -vecSunDir.zyx if I remember right- for some reason the light vector is flipped funny in A6....
