Oh, sorry, I made a mistake in the previous zip package. Please find the new shader attached.

2. Problem with overlapping opaque spine resources in Unity3D
I have read the article above. Is it easiest to use RenderTexture to give an alpha value so that the images do not overlap?
In version 4.0 and later, there is a tutorial for that function, but in 3.8 there seems to be no such thing.
You are correct, this example component has been added to 4.0 and newer versions of the spine-unity runtime. You could import just the contents of the Spine Examples/Scripts/Sample Components/SkeletonRenderTexture directory from the 4.0 spine-unity package to your 3.8 project, and the scene Spine Examples/Other Examples/RenderTexture FadeOut Transparency.
3. We are considering a version upgrade.
Our team of graphic designers are working on version 3.8.99.
If I change this version to 4.0.63 (the latest version excluding the beta version), is there any problem in importing the work of version 3.8.99?
You need to reexport your skeletons from Spine 4.0. In general we always suggest automating your export via scripts using the Spine Command Line Interface. We would recommend upgrading to 4.1 instead of 4.0, which will be released as non-beta very soon.
For a complete upgrade guide see:

4. Can't SkeletonGraphic use RenderTexture even in the latest version?
We haven't implemented such an example component yet, no. Currently we only have the render texture component available for SkeletonRenderer components (and subclasses SkeletonAnimation and SkeletonMecanim).
