I'm currently going through the shading and lighting class and really love this format. Are there any more classes planned in the future or this is something that was tested and not beneficial for the cgcookie citizens?
Last I remember, the team has more classes planned, it's just they are probably busy updating/making more content for Blender 2.8. I participated in several classes and the overall feedback was positive, so I'm sure they would like to do more classes in the future.
