Rutra,

With all due respect I beg to disagree. What you say would be true a few years ago.

Today written material is insufficient for two reasons. For the first it isn't detailed enough, and for the second you are no doubt familiar with the chinese proverb "One picture is worth a thousands words" which of course are even more true for film and video.

I am referring to all the excellent free and commercial training Videos out there. Personally I prefer AsileFX, not only "Getting started with Vue" and "whatsNew In Vue 7" but for instance,

Advanced Material Creation
Advanced Terrain Creation
Vue Tutorial Xfrog Plants

and so on. Excellent way to learn. I never go back!
