Misaki 18819130201 I'm sorry to hear you're having trouble. Could you tell us what version of Spine editor you are using? If you can reproduce the problem with a minimal Spine project, leaving only the part about the IK constraint, could you please email us the reproduced project?: contact@esotericsoftware.com Please include the URL of this forum thread in the email so we know the context. Then we can take a look at what's wrong.
