I have many bones with Damped Track constraint. Is there a way to simultaneously change the influence value for all of them?

you can use a script for that:

import bpy

new_influence = 0.5

for obj in bpy.context.scene.objects:
    if obj.type == 'ARMATURE':
        for bone in obj.pose.bones:
            for constraint in bone.constraints:
               if constraint.type == 'DAMPED_TRACK':
                    constraint.influence = new_influence

    $\begingroup$ I have no example to test it right now, but can you not simply select all bones and then Alt+click into the value field to change the value for all selected? Like you can in almost all other fields too? $\endgroup$ Commented May 25 at 17:29

Select all the bones and AltLMB on the value, type your value and Enter.

  • $\begingroup$ Thank you, this option works great too! I accept the previous option because it came earlier and because it does not require manually selecting all the necessary bones, but I will keep your option in mind, it is also very convenient, thank you very much! $\endgroup$
