Oh I think I know what’s going on. You see, you’d need to adjust your IK goals on different poses of your model. They will produce different results on different animations. For example, IK goals that are placed for an IK feet implementation that’s designed for walking animations or other animations that have similar leg & feet placement would not work on a jumping animation where the model bends it’s legs! Similarly, your IK goals that are placed accordingly to your aiming animation will produce different results on animations with different arm & hand placement.
