Blink/pop in loop animation

elpuntosobrelai

Hello there!

I have a problem with a loop animation. There seems to be a blink/pop between the last keyframe and the first one when I play the animation in the playback. I have lineal interpolation in my keyframes, so the animation should be fluid. I also found that the interpolation between the last and the first keyframe is different -like it was in stepped- when I move the cursor along my timeline pressing "shift".

You can see the problem in the right foot here:

I understand Spine doesn't interpolate the last keyframe with the first one in a slower speed, but I think in 100% speed the animation should work without any visible blink...

Thank you so much for your help!

The "pop" you're seeing is because the first and last frames aren't the same. This is the expected behavior. To fix it, you can copy all keys from frame 0 to your last frame.

Hi Shiu, thanks for answering.

As far as I know, in a loop animation the first frame and the last one can't be the same because there would be two identical frames together and the animation wouldn't be fluid either. Unless Spine has a special behavior for loop animations, I don't see how this will solve the problem.

The first and the last frame need to be the same. Spine will loop them correctly. Only if you're exporting a sequence of images will you need to delete the last frame manually.

Ok, that's good to know! Thank you for your time 🙂
