Currently, Spine does not have a feature that allows you to automatically trace all selected attachments at once. The Trace feature in Spine is designed to create a mesh hull automatically for individual attachments, and while it can be useful for optimizing texture space, it requires manual application to each attachment. The idea of applying Trace to multiple attachments simultaneously has been considered, but it is not yet implemented. This feature could save time for users who do not need detailed mesh editing and are primarily focused on optimizing their workpieces.
