To achieve scaling of bones while translating the Transform Constraint (TC) target without scaling the TC target itself, you can use a combination of transform constraints and possibly additional bones. Currently, Spine does not directly support converting translation to scale through a transform constraint. However, you can create a setup where a bone's scale is influenced by the position of another bone using indirect methods, such as using IK constraints with stretch enabled or by manually animating the scale based on the position of the TC target. This requires some creative rigging and animation techniques to simulate the desired effect.
