Yvan shared generousely all his knowledges and even more than what was initialy in the program. It gives you the will to dive completely into Octane and to learn even more! The fact all sessions from the Masterclass is recorded allows to re-watch as much as you want. Otherwise, the rhythm is fast paced and intensive, be prepared. In addition to advanced knowledges, Yvan succeed to created a chilling ambiant. I totally recommand it, great value for the money!
