If the draw order of meshes changes, the vertex/index buffers must be rebuilt. For the example character (the knight) shown animated on the homepage of the repo, rebuildMeshes is never called.
However, I can see that there is probably a good opportunity here for optimization for Spine characters/objects that do frequently cause calls to rebuildMeshes. Using pc.createMeshes is probably a bad idea. A single pc.Mesh should be created once, and the vertex/index buffers should only be recreated if the overall number of vertices changes (which presumably shouldn't happen in the case of a reorder of character parts).
Instead, the vertex/index buffers should just be refilled.

That's what I think. I tried to do it, but it didn't work. Maybe I wrote something wrong.

Spine plugin rebuilds meshes only if there are multiple atlases assigned to attachments and depth-order of those attachments changes.
So, I can recommend to minimise the number of textures or align attachments corresponding to texture to avoid reordering.
And unfortunately number of vertices is not constant.

But,There's probably more than one texture for animation.

I feel that rebuild has a high probability. Is there a better way, for example, to create a buffer mesh list and take it out?

I'll close this as the rendering system i question has been completely rewritten since then, and should perform a lot better overall.
