In Spine, reversing an animation curve directly by flipping it on an axis, like in Blender, is not currently supported. However, you can manually reverse an animation by duplicating it and then reversing the keys in the Spine editor. This involves selecting all the keys in the dopesheet, dragging them to reverse their order, and manually adjusting any curves as needed. While this process is not as straightforward as scaling to -1 in Blender, it allows you to achieve a similar effect by manually manipulating the keys and curves.
