I still think the best meshes are achieved with the fewest points possible, and placed by hand. If you press "Generate" while creating your mesh, Spine will automatically add points to it. (you can find the alpha setting in the Preview panel, next to the animation tracks, as well as in the Skeleton Viewer application)Ģ. You can't key it in a Spine animation but it's really nice to use programmatically. We also have Alpha in the animations that allows you to control how much an expression/a direction is applied to your character at runtime. You can find an example of that (and the explanation of how to do it) here: Twitch: Rigging in Spine Pt. there's an even better system than that if you want to control the system tridimensionality of a character, it just requires two bones, a transform constraint, and weighting the meshes correctly.
