title: Houdini voronoifracture group
body: <p>I have a little workflow with fractures and I'm having troubles at the moment of making the fracture apply only to certain group.</p>

  <p>And then I try to make the voronoifracture to take upon that group:</p>

  <p>The problem is that the model appears grayed out, as if no group were found despite it appears in the spreadsheet:</p>

  <p>I'm fairly new to houdini and in the lesson I've been following the fracture takes the group correctly. The lesson is recorded in houdini 16.5 though, and as I'm using 17.0 I'm unsure if the behaviour changed or if I'm doing something wrong with it.</p>
