I already knew a lot of the content, so I took the class at 2x speed. This is a good lecture for those who are new to ZBrush. However, those who have some experience are better off taking other lectures. The disappointing thing is that there are no detailed explanations, perhaps to lower the difficulty level. Those who are new to ZBrush should get a feel for it with this lecture and then look for more detailed lectures. And there is a part in the lecture that is different from what I know. This is a lecture about Subdivision. To create a higher resolution, Dynamic Subdivision is used instead of Divide. The explanation says that Subdivision is raised. As explained later, Subdivision is not actually Divide, so those who are listening for the first time may be confused.
