Well in reality you need to think of all light maps as shadow maps.

This?

Code:

---

material mtl_lightmap
{
  effect=
  "

  texture entSkin1;
  texture entSkin2;

  technique lightmap_mapping
  {
    pass p0
    {
      texture[2]=<entSkin1>;
      texture[3]=<entSkin2>;


      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;
    }
  }
  ";
}

(The code was for worldblocks and i changed the skinsources, should work)

Thanks, but it throws an error on this line:

colorarg1[0]=texture; // shadow map

"colorarg accepts only dwords and ids"

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;
    }
  }
  ";
}

Could someone here explain how to apply and use this process this in a 'for-dummies' step by step manner? (Assume I've already got the lightmap files...)

How is this different from what is being discussed here?
[urlhttp://www.coniserver.net/ubbthreads/showflat.php?Cat=0&Board=UBB5&Number=679845&Searchpage=1&Main=674842&Words=lightmap&topic=&Search=true#Post679845[/url]

The shader runs now, but it doesn't add the lightmap. I could upload a test model if you want to try again.

Did you trie my comments? Like renaming texture[0] to texture[2] etc?

@Jetpack_Monkey:
-Create a modell with one normal skin
-Create the lightmap somehow
-Add the lightmap the the modell as second skin
-Copy&Paste the code i´ve postet
-Copy&Paste this too:

Code:

---

action FX_lightmapped
{
   my.material=mtl_lightmap;
}

---

Good luck

Yes, I tried that (and I'm not quite that green), but it came out a bit strange. I could post a screen shot, but I don't think that would help much, so I have uploaded a model with a base texture and a lightmap applied for you to see for yourself: Download

If I add the material it behaves as I want it to do, so whats the problem?
The shader catches the normal texture and adds the light ^^

My bad, yes it does work. It looked different because it was a fair bit darker than I expected. Is there a parameter that can be adjusted to brighten or darken the effect to get it to look as it was lit in another application?
