<h2>Fix “RuntimeError: Error loading DNA: DNA signature mismatched, expected DNA, got ver?”<a class="headerlink" href="#fix-runtimeerror-error-loading-dna-dna-signature-mismatched-expected-dna-got-ver" title="Permalink to this headline"></a></h2>
<p>DNA files are stored as <a class="reference external" href="https://git-lfs.github.com/">LFS</a> files (Here is <a class="reference external" href="https://www.atlassian.com/git/tutorials/git-lfs">another explanaintion</a> what LFS is).
This problem occurs when repo is downloaded as zip, and github then does not download LFS files as whole file, but as some metadata file.<br />
Open that Ada.dna file in some editor file, from location were MetaHuman DNA Calibration is downloaded and then in
<code class="docutils literal notranslate"><span class="pre">data/dna/Ada.dna</span></code> (eg <code class="docutils literal notranslate"><span class="pre">c:/MetaHuman-DNA-Calibration/data/dna/Ada.dna</span></code> you will got this:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">version</span> <span class="n">https</span><span class="p">:</span><span class="o">//</span><span class="n">git</span><span class="o">-</span><span class="n">lfs</span><span class="o">.</span><span class="n">github</span><span class="o">.</span><span class="n">com</span><span class="o">/</span><span class="n">spec</span><span class="o">/</span><span class="n">v1</span>

<p>Which is not valid DNA file.</p>
<p>There is two ways to fix this issue:</p>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">git</span> <span class="pre">clone</span> <span class="pre">git</span> <span class="pre">clone</span> <span class="pre">https://github.com/EpicGames/MetaHuman-DNA-Calibration.git</span></code></p></li>
<li><p>manually download <span class="xref myst">Ada.dna</span> and/or <span class="xref myst">Taro.dna</span>, and put them in data directory
where you downloaded MetaHuman DNA Calibration. eg. <code class="docutils literal notranslate"><span class="pre">c:/MetaHuman-DNA-Calibration/data/dna</span></code></p></li>

<section id="how-do-i-distribute-a-maya-scene">
<h2>How do I distribute a Maya scene?<a class="headerlink" href="#how-do-i-distribute-a-maya-scene" title="Permalink to this headline"></a></h2>
<p>Your scene should work out of the box if you include the following in the distribution:</p>
<ul class="simple">
<li><p>Scene file (<code class="docutils literal notranslate"><span class="pre">.mb</span></code> file)</p></li>
<li><p>DNA (<code class="docutils literal notranslate"><span class="pre">.dna</span></code> file)</p></li>
<li><p>Workspace (<code class="docutils literal notranslate"><span class="pre">workspace.mel</span></code> file)</p></li>
</ul>
<p>All of these files need to be distributed together. If those files are not bundled and you experience some issues with you rig in Maya,
try the following steps:</p>
<section id="how-do-i-share-the-generated-files">
<h3>How do I share the generated files?<a class="headerlink" href="#how-do-i-share-the-generated-files" title="Permalink to this headline"></a></h3>
<p>If you want to distribute a generated Maya scene to other users, you must distribute the <code class="docutils literal notranslate"><span class="pre">.dna</span></code> file and <code class="docutils literal notranslate"><span class="pre">workspace.mel</span></code> together with the scene.</p>
</section>
<section id="how-do-i-open-a-generated-scene">
<h3>How do I open a generated scene?<a class="headerlink" href="#how-do-i-open-a-generated-scene" title="Permalink to this headline"></a></h3>
<p>Before you load a generated scene, follow these steps:</p>
<ul class="simple">
<li><p>From the main menu, go to File &gt; Set Project.</p></li>
<li><p>Select <code class="docutils literal notranslate"><span class="pre">workspace.mel</span></code></p></li>
<li><p>Set the containing folder (with generated maya scene, <code class="docutils literal notranslate"><span class="pre">.dna</span></code> file and <code class="docutils literal notranslate"><span class="pre">workspace.mel</span></code>).</p></li>
</ul>
</section>
<section id="how-do-i-change-the-dna-path-in-the-maya-scene">
<h3>How do I change the DNA path in the Maya scene?<a class="headerlink" href="#how-do-i-change-the-dna-path-in-the-maya-scene" title="Permalink to this headline"></a></h3>
<p>If you want to change the DNA path in the scene:</p>
<ul class="simple">
<li><p>In <code class="docutils literal notranslate"><span class="pre">outliner</span></code>, deselect <strong>DAG Objects Only</strong>:</p>
<ul>
<li><p><img alt="image" src="_images/change_path_outliner_settings.png" /></p></li>
</ul>
</li>
<li><p>Still in the Outliner, search for <code class="docutils literal notranslate"><span class="pre">rl4</span></code>. You will see a file whose name starts with <code class="docutils literal notranslate"><span class="pre">rl4Embedded_</span></code>. Click this file to select it.</p>
<ul>
<li><p><img alt="image" src="_images/change_path_outliner.png" /></p></li>
</ul>
</li>
<li><p>In <code class="docutils literal notranslate"><span class="pre">Attribute</span> <span class="pre">editor</span></code> you will be able to change the path with <code class="docutils literal notranslate"><span class="pre">Dna</span> <span class="pre">File</span> <span class="pre">Path</span></code>:</p>
<ul>
<li><p><img alt="image" src="_images/change_path_node_path.png" /></p></li>
