所以想問問看未來會不會有 "編輯頂點的時候可以在原本的範圍外新增頂點" 的功能
I think we first need to clarify what you mean by “outside the original range (原本的範圍外).”
As I understand it, you are referring to areas within the texture image but outside the mesh hull. Is that correct?
In Spine, vertices outside the mesh hull are considered invalid, and in the current version, they are automatically removed when the project is opened.
From your explanation, it sounds like you would like to temporarily place vertices outside the mesh hull during editing. However, allowing this introduces several usability concerns. For example, if a user unintentionally leaves such vertices behind, it becomes unclear how the editor should handle them—whether to block exiting mesh editing, display warnings, or automatically delete them.
Each of these approaches has drawbacks. Preventing the user from leaving the editing mode could be restrictive, while automatic deletion may result in unintended data loss, especially if the user switches context mid-work.
Because of these issues, allowing vertices to exist outside the valid mesh area, even temporarily, could lead to confusion and inconsistent behavior. For this reason, we believe it is better to consistently disallow placing vertices outside the mesh hull.
If I’ve misunderstood your intention, please let me know.
