Dragon Whelp Animated Mesh- Wing Socket?

Does anyone know what socket I would use to attach something to the dragon whelp's wings?

You can use the below code to print out the list of all available sockets of the animated mesh.

    for _, v in ipairs(mesh:GetSocketNames()) do
        print(v)
    end

For the Whelp Mob you will get the below results:

head
left_ankle
left_elbow
left_hip
left_knee
left_shoulder
left_wing
left_wrist
nameplate
neck
pelvis
right_ankle
right_elbow
right_hip
right_knee
right_shoulder
right_wing
right_wrist
root
spine
tail_1
tail_2
tail_3

So the answer to your question would be left_wing and right_wing.

That's wonderful, thank you.
