title: Unnable to modify or query image sequence path with token <f> from file nodes
body: <p>I have  referenced node, which path of the texture used is an image sequence:</p>
  
  <blockquote>
    <p>path\file.&lt; f >.iff   (I put it separated so that the editor doesn't change it)</p>
  </blockquote>
  
  <p>When i do getAttr </p>
  
  <pre><code>texture_path = cmds.getAttr('{}.fileTextureName'.format(file_node))
  </code></pre>
  
  <p>I get:</p>
  
  <blockquote>
    <p>path\file.0001.iff</p>
  </blockquote>
  
  <p>Which is the first image of the sequence. It is not the regular sequence, but it is an animated texture, meaning sometimes it is 0001, other times 0002... etc, depending on an animation curve attached to the image Sequence.</p>
  
  <p>How do I get the generic name set for the texture with the wildcard?</p>
  
  <p>If I edit that attribute, Arnold Render tells me  is an invalid token. Seems like there's something else happening underneath.</p>
  
  <p><strong>EDITED:</strong></p>
  
  <pre><code>import pymel.core as pc
  obj = pc.PyNode( 'textureFileNode')
  obj.fileTextureName.get()
  </code></pre>
  
  <p>Returns the path without the wildcard also.</p>
