One of the great things about online learning, especially a video format, is that you can learn at your own pace and watch and rewatch as many times as you want. Sometimes, I rewatch to remind myself and sometimes, a single view gets me what I wanted to learn. I even remember one particular video (Bartek Skorupa’s Wood texture in the Shader Forge series) that I’ve spent hours watching and rewatching because it was so dense and I still don’t feel like I fully understand it… but there’s one or two things from that video that I use all the time to this day when I’m making my own materials (with a few tweaks thanks to improvements in Blender over the years). I’ll even play a video and pause and rewind while I’m doing things step by step as I follow along. (Done this a lot with Human for example… one I’ve done several times partly because I keep getting distracted before I fully finish a piece 😀 ) The only right pace is to learn is the one that works for you 😀
