Can you make a 3D object in Spine?
You might think, "No way!" And you'd be right, because Spine is mainly for 2D.
But guess what? I actually made rotation famous 3D donut from Blender in Spine software. This isn't a pseudo 2.5D effect that most animators create in Spine. It's an actual 3D object, or more precisely, its projection onto a plane.
I did it in Spine. It was hard and took a while, but I made it.
