I haven't had no problems so far. Listfiles seem to be ok, and even expansion3.mpq has been read without problems. Same goes for wow-update-xxxxx.mpq, so I dont know what you mean, TOM_RUS.

loadMpq( mpq_h, "wow-update-oldworld-13286.MPQ" );
loadMpq( mpq_h, "expansion3.MPQ" );

weird, i cant load those mpq's in a build.. cmd error result below

Load "expansion3.MPQ"Cannot open K:\WowI\Data\expansion3.MPQ libmpq__archive_open failed
Load "wow-update-oldworld-13286.MPQ"Cannot open K:\WowI\Data\wow-update-oldworld-13286.MPQ libmpq__file_unpacked_size failed

edit: after looking in wow folder it turns out i dont even have a file named expansion3.mpq ^^ my bad

edit2: wow-update-oldworld-13286.MPQ seemd to be corrupt for some reason , got it from a friend of mine and it loaded fine

loadMpq( mpq_h, "wow-update-oldworld-13286.MPQ" );
loadMpq( mpq_h, "expansion3.MPQ" );

It's 13287
expansion3.mpq is if you have cataclysm.

wow-update-oldworld says 13286 : ) its listed in wowmapper source and my game folder.. tho i tried to load it with mpqeditor it says the file is corrupt for some reason.

theres the file wow-update-13287 that one reads just fine, was talking about oldworld one : )

Oh yeah sorry, I missed the oldworld part. Probably corrupt file then because I get no load errors from it. Try running the repair util.

I try to export the Area or tile to .obj (for recast) and this don't work fine.

Sample of result for PvpZone01_31_32: (img) UpImg Image Hosting-test.png (.obj) MEGAUPLOAD - The leading online storage and file delivery service

I use this code:

  // Save to .obj
  std::cout << "Make file: " << areaId << ".obj";
            // Write the vertex's  
  std::stringstream ss;
          for (int i = 0; i < vertices.size(); i++)
	  {
		  ss << "v " << (vertices[i].x) << ' ' << (vertices[i].y) << ' ' << (vertices[i].z) << '\n';
	  }
		  ss << '\n';
	  for (int i = 0; i < indices.size();)
	  {
		  ss << "f " << (indices[i++]+1) << ' ' << (indices[i++]+1) << ' ' << (indices[i++]+1) << '\n';
	  }
	  std::stringstream sFileName;
      sFileName << areaId << ".obj";
      std::fstream fs(sFileName.str().c_str(), std::fstream::out|std::fstream::binary);
	  fs << ss.str();
	  fs.close();
	  std::cout << "File saved.";

(before the code "// render loop")


Someone already had this problem? Because I not see an error in my code.

I try with others tile and zone, the m2 objet dump work fine but the matrix is beug.

Why do you use a stringstream? Just create a fstream and write directly to it like you do with your stringstream now. Also you open the file you write to in binary mode, whereas obj-files read by recast are simple ascii-files.

Because I have try to make a navmesh file before, but for try .obj file is Better.

I have edit my code, but this not fix the problem.

EDIT:

	// Save to .obj
	std::cout << "Make file: " << areaId << ".obj" << std::endl;
	std::ofstream fs("Dump.obj", std::ios::out | std::ios::trunc);
	for (int i = 0; i < vertices.size(); i++)
	{
		fs << "v " << (vertices[i].x) << ' ' << (vertices[i].y) << ' ' << (vertices[i].z) << '\n';
	}
		fs << '\n';
	for (int i = 0; i < indices.size();)
	{
		fs << "f " << (indices[i++]+1) << ' ' << (indices[i++]+1) << ' ' << (indices[i++]+1) << '\n';
	}

	fs.close();
	std::cout << "File saved." << std::endl;

This is the new code but the result is same.

Sort of works, it looks kind of cool even though its wrong... Im not sure what 2 objects are but I dont play alliance much and visit these zones even less. The tree-like? thing to the left and the object past the mountains to the right.

[hamburger12]

This works verry well for me:

  std::fstream fs1("test.obj", std::fstream::out|std::fstream::binary);

  for (int i = 0; i < vertices.size(); i++)
  {
	  fs1 << "v " << (vertices[i].x) << ' ' << vertices[i].y << ' ' << (vertices[i].z) << '\n';
  }

  // Create faces based on the indices
  for (int i = 0; i < indices.size();)
  {
	 fs1 << "f " << indices[i++]+1;
	 fs1 << ' ' << indices[i++]+1;
	 fs1 << ' ' << indices[i++]+1 << '\n';
  }

Any images of your recast display?

I need to find a decent LoD algorithm though. The meshes are huge and I don't really need that much precision.

[The-Guardian]

I'm getting this error, the only thing I've gotten it to compile is Elwynn forest.

Ive tried using the wdt file and cmp file, nothing works.

Have a look at MeshLab. You can use "Merge Close Vertices" and "Quadric Edge Collape Decimation" to reduce the number of faces.
