    Issue with “Foot Heel” rig mechanism in Blender 4.5

    Arthur S(Devarth)
    posted to: IK-FK Bendy Leg Demo
    Hello,

    I’ve run into a problem with the rig: the “Foot Heel” mechanism isn’t working.
    All parent relationships and constraints are set correctly.

    However, in Blender 4.5, the “Limit Rotation” constraint no longer has the “Legacy Behavior” option.
    As a test, I opened the same rig in Blender 3.6, and everything worked correctly there.

    Could you please help me understand what might be causing this issue in Blender 4.5?

      HI Arthur DDevarth ,

      When you say:   "... in Blender 4.5, the “Limit Rotation” constraint no longer has the “Legacy Behavior” option."

      What do you mean by that?

      Also, as a side note, adding a timestamp to your questions is really helpful😉

      Hello, Martin.
      I don’t have the “Legacy Behavior” option in the Limit Rotation constraint. My Blender version is 4.5.4.

      Hi Arthur,

      Are you using an Addon (or a Script)?

      If you Open a new File, is the Legacy Behavior available?

      Yes, I disabled the rigging add-ons and restarted the program. Everything worked—thank you! I’ll continue with my training calmly.

      The Python API changes (more or less) almost every Blender Version , so it's always possible that an Addon (temporarily) breaks.

      You might want to report the issue to the Addon Developer/Maintainer.

      What add-on is that DDevarth ?

      I'd like to check it out.
      I'm not sure if it would speed things up, but it's worth taking a look to see if it has potential.

      Hi Katherine @katriliza ,

      "Since the Legacy Behavior option was removed"

      Just to be clear, that was not removed; the option is still there, even in 5.1.

      It was an Addon that caused the issue.

      I'm glad you asked about it otherwise I wouldn't have thought about enabling the Legacy Behavior option (Blender 5.1 here).
      It's not in the schematics and I guess I missed it in the video...
