Hi,
There is a lot of tutorials about using Substance Painter with Blender.
In most cases, these tutorials concern maps like Diffuse, Metallic, Normal, Roughness, etc…, but rarely explains how to have a good match with opacity maps (transparency).
In all modesty, I do not know if the solution I use is the best, but it gives a good match for opacity maps between SP and Blender.
Of course, all reviews / corrections / improvements are welcome …

Substance Painter Tutorial – Opacity (how to create opacity channels and view opacity in the viewport.)
To automate the creation of the nodes:
- use Node Wrangler (enable addon in user properties) and use shorcut CTRL+Shift+T
or
- install the addon of Michel Anders (varkenvarken) ==> thread on BlenderArtists
- available on his Github
- available on his Blog
