Answers.Text: Thanks. If I set a guide layer in a pre-comp, can I jump back into the main composition and expose the guide layer there also?

Answers.Text: You know what, I've just found out that guide layers don't show up in nested comps. You'd have to make it a normal layer and turn it off before render time. I'll edit my answer.

Body: <p>I have an icon I'm animating within it's own composition. I want the comp size to be comparable to the final size of the icon, so when I lay it down in other projects, I have a good understanding of where the icon will end up.</p>
  
  <p>As the icon animates in, it extends beyond the size of its composition. Can I set the composition to render display elements outside of its boundary box?</p>
  
  <p>Thanks,

  As the icon animates in, it extends beyond the size of its composition. Can I set the composition to render display elements outside of its boundary box?
