Is the shader gizmo available somewhere? I don't suppose it's vital to understand the lessons, but I like to follow along as closely as possible so it's easier for me to see if I'm doing something wrong.
I had the same question too, I keep forgetting that I need to back up to the main page to get all of the course files. It might make sense to include the course file for the specific lesson within the course files section of that specific lesson. Right now it's not very useful with just the video file.
