Both valid concerns. First, I’ve done a really bad job keeping the email list up to date. Been juggling a lot of balls (production, artist management, platform trial and error, announcements, etc etc) and the e-mail ball has been mostly fumbled. But I promise to send out an email for the launch, for sure!
Next, your concern about future updates. I’m including a 30-day money-back guarantee, so you can hop on and decide if you feel like it’s everything you hoped to get for the money. Already, there’s a 21st session, and we have at least 4-5 more planned. Sessions typically run with 1-3 hours of video content, and most of them have a downloadable source file. It’s straightforward for me to add a mini video to a session to supplement what’s there, and clarify anything that was missed, which is absolutely my plan. I’ve got a couple TAs on hand who are gonna help me parse the feedback from the private forum, to get the right updates out to you as quickly as possible.
And yes, the course does cover texture creation, and also shows a more advanced material being created. For day-to-day material creation, we go with the same method I learned with, which is a fully-featured Uber shader. You’ll be creating many child materials with that thing, that will cover the League style as closely as possible.
Hope that answers your questions!
