Spine

  • Limited to 2048 pixel maximum atlas size on one dimension due to Apple device constraints
  • Can constrain only up to 2 bones at the same time; more requires creating hierarchy of constraints
  • PNG metadata can significantly increase file size and cause editor freezes
  • Export artifacts may include black outlines and white glows with translucent pixels
