How to get rid of invisible tween ?

trafcio

HiI have a problem with linked frames in tween.
In animation programs, each frame is a separate drawing.
I would like to have this effect in this case.

Unfortunately, whatever I do, the scale change has an invisible tween.
I flip the hand image from scale 1 to -1
Is there a way to get rid of this invisible tween ?

I attach a link to a video showing the problem

Your video isn't public, so we can't see it.

No interpolation (tweening) is invisible. Use the Graph view to see your values over time.

You just need to use a stepped key:

Stepped key not work in this case :/

trafcio Hmmm, I tried to reproduce this issue, but could not. Could you please email us a project that can reproduce it?: contact@esotericsoftware.com
You do not need to attach the images of the skeleton, so just send the Spine project file. We would appreciate it if you could include a link to this thread in the body of your email so that the context is clear.

I sent an email with the project.

trafcio Thank you for sending your Spine project file! The cause is that the translate key of the IK target bone at the left elbow (IK_L_elbow) is not a stepped key. This IK constraint enables Compress and Stretch, so when this bone is translated, the constrained bone is scaled. The scale keys are not related to this problem. (You can verify that the scale is working correctly by deleting the other keys, leaving only the scale keys.)
So try setting the key of the IK target bone to stepped and see if that fixes the problem.

We'll look at the project soon and get back to you, but again the Dopesheet doesn't show your curves. If you are having an issue with curves between keys, look at the Graph, not the Dopesheet.

Also note you can hold shift to move the timeline position between integer keys, as happens during playback.
