Hi. Sorry for my english.
I'm newbe in Unity. I need animate graphics for my game. A lot animators offer to me to do animation in Spine.
I tryed to install it in my project, add "Raptor" from examples to scene and I see that animation is not smooth in Unity editor and android export. It's looks like it's framed/20 FPS.
Like here http://ru.esotericsoftware.com/spine-demos right "Sprite sheet" variant. I see few tails in one moment. While in browser left "Spine" is ok, looks like 60 fps.
Why?
A single instance of the Raptor example skeleton should never cause any framerate problems. Please note that when selecting objects in the Scene it will decrease performance in the Game view, however there you should trust the displayed fps in the Stats of the Game View window more.
Anyway, you said it also had bad framerate when deployed to your Android device.
Is this a clean Unity project and scene with no other 3rdparty assets in it?
How did you create the Raptor instance in the scene? Which asset exactly did you drag into the Scene or Hierarchy panel?

What do you mean by this?
Like here with the white axe
This effect is only coming from your display, there is no motion trail in the video. You can check it out at 0.25x speed.
Yes, you are right. Thank you for your answer!
You're welcome.
