old substance painter tutorial

Last year, I taught a class at Studio Arts online.  I would frequently make supplemental videos for the people in class.  One session I had all kinds of crashes in Zbrush, Maya and Substance.  it was a weird day, and I felt bad afterwards, so I made this video for the people in the class as a sort of mea culpa.    It's super basic, but if you're new to substance painter, maybe something in here can help a little.
