I made a robot leg for rigging test for the piston attached to theleg.
I used simply LockedTrack for making piston move along the leg movement.
When I move IK leg from pose mode, it works just like I expected but, when I play animation or render animation,
somehow the piston sticks out like the picture.
It doesn’t happen in pose mode. I guess there is a precision setting of bone or Track to constraint somewhere and I don’t know? if you knew the reason of this issue, please tell me what is the problem.I attached the blend file.
Thank you in advance
