How to combine texture files after export from Substance Painter with using Photoshop?!

Hi guys. In this tutorial I will explain how to combine the textures of different sets of materials after unloading them from Substance Painter. Unfortunately, in Substance it is not possible to export the entire texture at this time if you have used several texture sets. But there are a few simple ways to solve the problem. I will talk about the most simple in my opinion - using photoshop.
