I am an artist and don't know anything about shaders.
Please help me.
Why don't these shaders work with the current version of gamestudio A6?
Can somebody fix them for me?

Code:

---

 var d3d_automaterial=1;



bmap b_luminosity1=<luminosity1.tga>;

material checker1 // material name = level surface texture name
{
  skin1=b_luminosity1;

  effect=
  "

  texture mtlSkin1;
  texture entSkin1;

  technique luminosity_mapping
  {
    pass p0
    {
      texture[2]=<entSkin1>;
      texture[3]=<mtlSkin1>;


      colorarg1[0]=texture;  // shadow map
      colorarg2[0]=diffuse;  // vertex lighting
      colorop[0]=add;        // add vertex lighting to shadow map


      colorarg1[1]=texture;  // color map
      colorarg2[1]=current;  // (shadow map + vertex lighting)
      colorop[1]=modulate2x; // modulate color map with (shadow map + vertex lighting)
      resultarg[1]=temp;     // output to temp register


      colorarg1[2]=texture;  // color map
      colorop[2]=selectarg1;

      magfilter[2]=linear;
      minfilter[2]=linear;
      mipfilter[2]=linear;
      texcoordindex[2]=1;


      colorarg1[3]=current;  // unshaded color map
      colorarg2[3]=temp;     // shaded color map
      colorarg0[3]=texture;  // luminosity map
      colorop[3]=lerp;       // interpolate between shaded color map and unshaded color map depending on luminosity map

      magfilter[3]=linear;
      minfilter[3]=linear;
      mipfilter[3]=linear;
      texcoordindex[3]=1;
    }
  }
  ";
}
if you want to apply the effect to several different level textures you could do it this way:

bmap b_luminosity2=<luminosity2.tga>;
material groundtexture2
{
  skin1=b_luminosity2;
}

bmap b_luminosity3=<luminosity3.tga>;
material metaltexture_tga
{
  skin1=b_luminosity3;
}
...

starter copy_effects()
{
  wait(1);
  groundtexture2.effect=checker1.effect;
  metaltexture.effect=checker1.effect;
  ...
}

Code:

---

 var d3d_automaterial=1;

bmap b_detail1=<detail1.tga>;

function init_detail_mapping
{
  bmap_to_mipmap(mtl.skin1);
}

material checker1 // material name = level surface texture name
{
  event=init_detail_mapping;
  skin1=b_detail1;
  effect=
  "
    texture mtlSkin1;
    technique detail_mapping
    {
      pass p0
      {
        texture[2]=<mtlSkin1>;


        colorarg1[0]=texture;  // shadow map
        colorarg2[0]=diffuse;  // vertex lighting
        colorop[0]=add;        // add vertex lighting to shadow map
        resultarg[0]=temp;     // output to temp register


        colorarg1[1]=texture;  // color map
        colorop[1]=selectarg1;


        colorarg1[2]=texture;  // detail map
        colorarg2[2]=current;  // color map
        colorop[2]=addsigned;  // add detail map to color map
        texcoordindex[2]=1;
        texturetransformflags[2]=count2;
        texturetransform[2]={8.0,0.0,0.0,0.0, // detail map u scale
                             0.0,8.0,0.0,0.0, // detail map v scale
                             0.0,0.0,0.0,0.0,
                             0.0,0.0,0.0,0.0};
        magfilter[2]=linear;
        minfilter[2]=linear;
        mipfilter[2]=linear;


        colorarg1[3]=temp;     // (shadow map + vertex lighting)
        colorarg2[3]=current;  // (color map + detail map)
        colorop[3]=modulate2x; // modulate (color map + detail map) with (shadow map + vertex lighting)
        magfilter[3]=linear;
        minfilter[3]=linear;
        mipfilter[3]=linear;
      }
    }
  ";
}

How don't they work? what errors are generated? Btw since these aren't shaders but fixed function effects they ought ot work on most any card.

I get something like this for both of them:

The code is i believe for the Dx8 version of the engine, to convert this Dx9 you may need to make some simple changes, unfortunately i don't what changes are needed for fixed function effects. Maybe someone else
