I’m not sure I follow RE: moving pivot point. You can change pivot point of a frame in sprite editor (or for all frames using Property Matrix), but it’s an editor-only concept. baked render data is ‘rezeroed’ so that pivot lies at local origin.
Longer term I’d like to have an animated transform track in each flipbook, so you can translate, rotate, or scale frames over time, but there isn’t anything like that yet.
Cheers,
