I am using Spriter Pro with Unity, with the help of https://github.com/Dharengo/Spriter2UnityDX exporter
I have some issue with the sorting of the sprite's Z Order.
Sprite that are assigned to be at the back is appearing in the front after exporting.
The spriter prefabs are generated via code. In other words, they are not placed in using the Unity Editor.
I did set the exported prefab as a child of another object.
