title: Conversion of NWD (FBX) to SVF - Textures not found in Forge Viewer
body: <p>We recently discovered an issue for conversion of NWD files (with FBX) to SVF. It used to work perfectly prior to April. We still reference the same Forge libraries that we did when it worked.</p>
  <p>The issue is that the converted SVF file does not show textures on model elements because our viewer is asking for texture files named</p>
  <pre><code>&quot;navis_example_file_svf_tex_mod.jpg&quot; 
  </code></pre>
  <p>while the corresponding resource we downloaded from our bucket is</p>
  <pre><code>&quot;navis_example_file.jpg&quot;
  </code></pre>
  <p>We have asserted that the model manifest contains &quot;navis_example_file.jpg&quot; without the &quot;_svf_tex_mod&quot; suffix.</p>
  <p>However we found a reference to &quot;navis_example_file_svf_tex_mod.jpg&quot; inside <strong>Materials.json</strong> associated with the model. Our workaround to make the model show textures is to change the reference in Materials.json to match the jpg file.</p>
  <p>Are there any changes in the APIs for uploading/converting/downloading SVF models that could cause this issue?</p>
  <p><strong>Server-side environment:</strong> Autodesk.Forge 1.9.0 (Nuget)</p>
  <p>We are using EMEA region for the whole process, using these endpoints:</p>
  <ul>
  <li>BucketsApi (GetBucketDetailsAsync, CreateBucketAsync, GetBucketsAsync)</li>
  <li>DerivativesApi (GetManifestAsync, TranslateAsync)</li>
  <li>ObjectsApi (UploadObjectAsync, UploadChunkAsync)</li>
  </ul>
  <p><strong>Client-side environment:</strong> Forge viewer (7.40).</p>
  <ul>
  <li>Initializing the viewer:</li>
  </ul>
  <pre><code>Autodesk.Viewing.InitializerOptions =
  
  { env: 'Local', useADP: false, useConsolidation: true, useCredentials: true }
  </code></pre>
  <p>Loading the model:</p>
  <p><code>this.viewer.loadModel(&quot;svf urn from our own server&quot;)</code></p>
  <p><strong>Update</strong></p>
  <p>We tried to load the model directly from the Autodesk server and it works, contrary to our offline version with downloaded derivatives. We used these the settings below. The textures all have the &quot;svf_tex_mod&quot; suffix in this case.</p>
  <pre><code>const AUTODESK_ENVIRONMENT_OPTIONS: Autodesk.Viewing.InitializerOptions = {
    env: 'AutodeskProduction',
    accessToken: &quot;&lt;Access token here&gt;&quot;,
  };
  
  ...
  
  Autodesk.Viewing.Document.load('urn:&lt;URN here&gt;', successCallback, ...);
  </code></pre>
