Welcome Alexey! We only teach Substance in the context of how to use it with Blender, so if you’re wondering about the workflow we’ve got you covered:

https://cgcookie.com/course/texturing-weapons-in-blender-and-substance-painter
But we don’t teach the fine details of Substance Painter itself, since you can find pretty much everything on Allegorithmic’s own channel. We also don’t have anything covering Marmoset since it’s not part of our pipeline for either games, animations, or VFX.
But if you have any questions about those, feel free to ask here since others in the community might use them as well.
