Also believe it or not, Blender is such a huge beast, you tend to forget a lot of stuff, that even teachers have to re-watch their own tutorials to remember how to do something. So that to say, don’t worry too much, there is no brave Blender ultra warrior out there that is unchallenged by the huge amount of information 3D software’s tend to demand from you. Some things sticks, others don’t and you have to troubleshoot a lot, research stuff you once already knew and Blender develops much faster that you can learn stuff. Such is the way (Crowd repeats in unison) Such is the way!.
