2D Spine Animation Blending Question

TaeWoong

While studying 3D character animation, I learned a technique called blending.

Using blending, I saw that when the IDLE and RUN animations of a 3D character switch, they switch naturally.
(Without the need for separate IDLE TO RUN / RUN TO IDLE animations)

So, I wanted to apply this technique to 2D Spine, so I tried to apply it in the same way, but strangely, the 2D Spine character broke...

Can't I mix animations of 2D (or 3D) characters made with Spine using blending?

I wonder if it's possible to apply blending, because it has the advantage of not needing intermediate motion animations and making it easier to manage the animation status window!

Yes, you can achieve animation blending in Spine for 2D characters, similar to how it's done in 3D animation. Spine supports blending between animations, which allows for smooth transitions without needing separate intermediate animations. This is done using the AnimationState class, which can mix the previous and next animations during transitions.

Here are some key points and resources to help you with animation blending in Spine:

AnimationState Mixing: You can use the AnimationState class to mix animations. This allows you to blend from one animation to another smoothly. For example, you can blend from an IDLE animation to a RUN animation without needing a specific transition animation.
Mix Time: You can set a mix time for the transition between animations. This determines how long the blending will take. The Skeleton Viewer can help you visualize how different mix times affect the blending.
Multiple Tracks: You can use multiple tracks to blend animations. For example, you can have a base animation on one track and blend another animation on a different track.
Examples and Documentation: The Spine Runtimes Guide provides detailed information on how to apply and blend animations. Additionally, the Spine Preview tool allows you to preview how animations blend in the editor.

Here are some relevant links and examples:

By using these techniques, you can achieve smooth transitions between animations in Spine, making it easier to manage your animation states without needing intermediate animations.

@TaeWoong When using Unity you automatically receive mixing transitions between animations, unless you change the Mix Duration to 0.

You can check out the example scenes that come with the spine-unity package, located in the
Spine Examples directory. Also see the documentation here.

I figured out what the problem was.

In the case of IDLE and WALK in 2D Spine animation, since both use side-parting, they are naturally mixed when blending animations.

However, in the case of IDLE and RUN, IDLE is a side part and RUN is a half-side part, so when using animation blending to switch animations, the graphics break.

I tried looking for a way to solve this, but it's hard to find a clear method.

In this case, for animation switching between side-parts and half-side parts, is it common for Spine animators to create separate linking movements?
