Now it works, FF effects are case-sensitive forgott it
Code:

---

material mtl_lightmap
{
  effect=
  "
  texture entSkin1;
  texture entSkin2;

  technique lightmap_mapping
  {
    pass p0
    {
      texture[0]=<entSkin1>; //Try texture[2] if it don´t do it´s job
      texture[1]=<entSkin2>; //Try texture[3]


      colorArg1[0]=Texture;
      colorArg2[0]=Diffuse;
      colorop[0]=add;        // add vertex lighting to shadow map


      colorArg1[1]=Texture;
      colorArg2[1]=Current;  // (shadow map + vertex lighting)
      colorop[1]=Modulate2x; // modulate color map with (shadow map + vertex lighting) (Test Modulate4x / Modulate2x / Modulate)
      resultarg[1]=Temp;     // output to temp register


      colorArg1[2]=Texture;
      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;
    }
  }
  ";
}
