title: Why Blender exported shader (*.frag, *.vert) are turning into black color in Irrlicht
body: <p>I ran into "official tuto 10 Shader" in Irrlicht 1.8.3, and i modified this official example to use the shader that I exported from Blender using the addon: <a href="http://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Game_Engine/Export_GLSL" rel="nofollow">http://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Game_Engine/Export_GLSL</a></p>
  
  <p>The exported material is just composed of simple diffuse and specular color that is not black at all, but in Irrlicht it looks Black</p>
  
  <p>Here is part of the shader tuto in Irrlicht SDK (i just modified the names of the shader loaded) assuming no CG used, and advanced Shader used.</p>
  
  <pre><code>case video::EDT_OPENGL:
      if (UseHighLevelShaders)
      {
          if (!UseCgShaders)
          {
              /**I MODIFIED NAMES OF THE ORIGINAL FRAG VERT FILES BELOW*/
              psFileName = "../../media/mat_Material.frag";//opengl.frag";
              vsFileName = "../../media/mat_Material.vert";//opengl.vert";
          }
          else
          {
              // Use HLSL syntax for Cg
              psFileName = "../../media/d3d9.hlsl";
              vsFileName = psFileName; // both shaders are in the same file
          }
      }
      else
      {
          psFileName = "../../media/opengl.psh";
          vsFileName = "../../media/opengl.vsh";
      }
      break;
  }
