title: How to import 3D scene (.obj file with .mtl file)
body: <p>I bought a 3D Model of a room. The model is in the <code>.obj</code> format. Now, I'm trying to import this model into Unity3D.</p>
  
  <p>The Model came with:</p>
  
  <ul>
  <li><code>5</code> x <code>.obj</code> files  </li>
  <li><code>5</code> x <code>.mtl</code> files</li>
  <li><code>n</code> x <code>.jpg</code> files</li>
  <li><code>n</code> x <code>.tga</code> files</li>
  </ul>
  
  <p>The <code>.mtl</code> files contained paths that do not exist on my PC. So I removed the paths. The images files (<code>.jpg</code> &amp; <code>.mtl</code>) are in the same directory as the <code>.obj</code> files. When I tried to import the <code>.obj</code> files, the room has no material on it. 
  I then tried to use the FBX converter (with "Embed media" checked) to convert the <code>.obj</code> to <code>.fbx</code> and still when I import it, there is no material on the 3D room (it's invisible). I also tried importing all the <code>.jpg</code> and <code>.tga</code> files to a folder underneath the root Assets folder in Unity then importing the <code>.obj</code> and <code>.mtl</code> files.</p>
  
  <p>What am I doing wrong? Does Unity3D use the <code>.mtl</code> to determine where to find the image files required? Is there an import log that could possibly shed some light?</p>

  <ol>
  <li><p>I edited all my <code>.mtl</code> files and removed the paths so its just the image filename (i.e. <code>map_Ka Arch 53-wood 14.jpg</code>).</p></li>
  <li><p>I copied all my <code>.jpg</code> and <code>.tga</code> files to a <em>"Textures"</em> folder in the same directory.</p></li>
  <li><p>I used the FBX Converter to convert the <code>.obj</code> files to <code>.fbx</code>.</p></li>
  <li><p>Imported the <code>.fbx</code> into Unity3D.</p></li>
  </ol>
  
  <p>It still creates a model with no material (invisible) on it but the material folder it automatically creates upon import has much less files in it and those files map to images I imported under my Assets folder -- maybe this is progress? Not sure...</p>
  
  <h3>UPDATE [8/25/2015] #2</h3>
  
  <p>Possibly my model is importing correctly but I'm not setting something right? My <code>.fbx</code> model that I imported has number of Mesh filters underneath it. Each Mesh filter's Albedo does map to an image that I imported underneath my Assets folder (see screen shot) but still still when I drag the root model into my scene it is transparent -- why?</p>
  
  <h3>UPDATE [8/27/2015]</h3>
  
  <p>I was not able to get the <code>.obj</code> / <code>.mtl</code> combo working. I was able to get the author to convert to fbx so I'm trying to get that working as well (same issues I'm having with my converted fbx files). I create a new SO question at this point (<a href="https://stackoverflow.com/questions/32259456/imported-fbx-model-is-transparent">Imported .fbx model Is Transparent</a>)</p>
