I have these copied transform frames on a mesh from another animation, and it seems when I paste them to another skin, they stop working? (the new skin has a mesh on the same attachment I'm trying to deform)
Discovered the solution to this can be a 'linked mesh', it's posted in the "meshes" page of the spine user guide,
Meshes - Spine User Guide
but by creating a linked mesh, you can animate that and it will work the same way across skins.
