Answers.Text: I imported my masks from Mocha AE, thus I got myself a vector mask and with that I would like to mask out some things including brush strokes. Any ideas on this one?

Body: <p>I've run into a little snag.
  I can't seem to mask out some of the brush that I've used on a an empty layer.</p>
  
  <p>I create the mask but it simply doesn't mask out anything, it does however mask out pixels when I did some experiments.</p>
  
  <p>How can i get this done?</p>
  
  <p>Thanks!</p>
