Hi khatri3d ! That’s actually not the expected behavior. The Create and Update buttons have different purposes:
- Create is meant to generate new in-between cels between the two selected cels
- Update is used to modify an already existing generated range
So ideally, Create should already work on the first click.
I’ve tested it on my end and it’s working correctly (Aseprite v1.3.16.1 with Tweencel v2.2.2), so this might be a version issue or something specific in your setup.

If you can, could you share a quick screenshot or short video of what you’re doing? That would really help me understand what’s going wrong and give you a proper fix.
