generate mesh tangent vectors by code

 void CEntity::SetGenerateTangents(const STRING &meshType)
   {
      MeshPtr pMesh = MeshManager::getSingleton().load(meshType,
         ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME,   
         HardwareBuffer::HBU_DYNAMIC_WRITE_ONLY,
         HardwareBuffer::HBU_STATIC_WRITE_ONLY,
         true, true);

      unsigned short src, dest;
      if (!pMesh->suggestTangentVectorBuildParams(src, dest))
      {
         pMesh->buildTangentVectors(src, dest);
      }   
   }
