I'm working on a character who has a short looping animation (Jetpack exhaust) as part of his model. The rotation and scale is changed with bones, but the sprite loop itself never changes. At the moment, this involves going in to every animation and copy-pasting the attachment keyframes, which is messy and tends to stutter between animations in gameplay. Is there any way to set up the character so that the animation itself is part of the attachment and just goes without further input? Sort of the way a nested MovieClip would behave in Flash?
Sub-question: Are there any tutorials for the AE-to-Spine script? I've tried a few times and can't get it to work.
