Well, I slow-rolled through the entire workflow twice. And after 2 straight weeks, at least 4 hours a day (minus weekends) I have been UNABLE to complete the rest of this Robo-Orb. Tried everything I know and have learned (or at the least comprehended and retained). I don't want to give up, but I'm so frustrated. It seems that when I try to incorporate the skills, tricks, and tools I learned, they hardly ever work like they do in the tutorial video. Is this a Mac issue because when I try to follow some things in the video, they don't work that way in my blender version (2.76), What can I do? HEEEELP!
