hi,the version I use was the latest of 3.6 Unity
I do the steps in https://github.com/pharan/spine-unity-docs/blob/master/spine-unity-skeletonrenderseparator.md
bug I got the incorrect result.
the parent mesh and material was not change, and the child 1 and 2 mesh and material was none.
Is there any step I miss? thanks for help.
