Bitmap Sequence Rendering

Probably this is very simple…but its killing me.
I have 3 movieClips on stage

  • clip1 plays, the last frame of which trigers clip2 to begin playing
  • clip2 triggers clip3 and clip3 triggers clip1…so its a loop.

I need to render one loop of the above as bmp/ sequence.
but since its a movieclip( and not layed out on the main timeline) Flash just renders only the first frame.

help!
