Let me know if you have any questions about using Substance. Also, you can work with scans directly in our toolset. We are working on a new update to Painter that allows you to edit scans across multiple channels. Check out this video. Scan Blending Demo in Substance Painter - YouTube
Cheers,
Xnormal is the only option you should consider for map baking (High Poly Normal, AO, Curvature, etc.).
Then use Substance Designer/Painter for Diffuse(Albedo), Metallic, roughness, and detail normal (created from B2M or other tiling normal map creator).
There is no reason to use a program that crashes constantly and requires photoshop…

Ehhhh, using Substance Painter to bake is a much faster and easier way to do things. If you know what your doing.
