Hi ,
Noticed something the other day while animating, I switched stretchy legs on for a moment while he was in a pose and the entire leg stretched while maintaining the rotation, shouldn’t the leg only stretch outward when straight?
This is caused by the incorrect joint being used to calculate the end point of the stretching distance locator / node.
Probably you have it set to the IK ankle joint, when it should be the reverse lock ankle joint (or node, depending on how you’ve set it up).
Cheers
