Thank you
I added the Sort Group component, it works!

Spine runtime library version: 3.6
Unity editor version: 2017.4.0f1(x64)
Issue: Spine animation rendering order incorrect.

I have set the order of multiple pictures in spine,
In Unity, I only use one Skeleton Animation component to render it.

But when I render multiple identical objects or different objects at the same time, rendering errors occur.

Even our boss animation has this problem too.
