It would be useful for cut scenes and for more modular animations if you could link multiple animations inside a animation and optionally layer them to perform additive animation inside of the Spine Editor. I know the preview view has the ability to do additive animation but I would like the ability to store the layering and blending inside an animation so I can use the additive / multiple linked animations with no additional setup required on the runtime side. I would also like to export a layered and blended animation to video / gif.
Although, the the requests go togther well I think this is two features. One is the ability to link to multiple animations inside an animation and the other is the ability to blend between the animations.
This is kinda of similar to Blender's NLA editor. I think the Godot Spine2D runtime actually does this using Godot's animation player, not sure about additive animation but it seem like the linking part is there.
