Currently, exporting hybrid animations directly from Spine is not supported. To create still images or videos that combine multiple animations, you need to use Spine runtimes, such as the spine-unity runtime with the Timeline extension in Unity. This method allows you to mix animations and export them as needed. Unfortunately, there is no direct feature in Spine to export hybrid animations as GIF or AWEBP.

Unfortunately, exporting the result of combining multiple animations as a video file directly from Spine is not possible.

If you have some experience with Unity, you can follow the video in this blog post, which guides you through achieving your desired result.
