I've done a few texturing and substance painter courses in the past, and I've got to say that this one is the best by far. You get to learn pretty much everything about substance painter tools, and also some useful tricks and alternative workflows. I really like how the instructor shows multiple alternative ways of obtaining a certain result, since that leads to a better understanding of the different tools and their application. The only complaint that I have is the excessiveness of having so many 4k texture sets in the barrel bot course section, which is not very practical for most projects and can really slow things down depending on your PC. All in all, I'd say it's a must-buy before they retire it.
