I went thru a number of sections last night...kinda skipping around. So far....one of the best I have ever seen (and I have seen alot...probably too much...LOL). Mark your explanations are clear, concise and the way you relate a function to real world examples is invaluable...brilliant really.  I thought I understood alot of Carrara...been a user on and off since Ray Dream, but I have learned something in every video I have watched.
Congrats on a great job. I look forward to finishing the rest of videos and doing better 3D work in C6 Pro!!
