I'm getting the same problem with crashing EVERY time! I have a brand new MBPro (early 2016) fully upgraded: 3.1 GHz Intel Core i7, 16 GB 1867 MHz DDR3, Intel Iris Graphics 6100 1536 MB. This is the most powerful 13" Mac money can buy. Unfortunately, the new MBP's forbid the replacement of the graphics card. If you do you forfeit and lose your Apple Care Plan. So, with a $2700 computer, I'm absolutely unable to finish this workflow because when I get to the multi-res bake portion it crashes inescapably. So, am I to believe that a near $3K piece of hardware can't accomplish this task? This seems utterly absurd to think. I also am not tracking with this workflow well, as it seems just a bit disorganized and cluttered with assumptions. I'm really not trying to be discouraging to Kent; I know he knows his stuff, but instruction seems a bit underpar on this one. If this expensive of a computer can't perform the lesson tasks (and it can't), I'm left wondering, what ELSE will I not be able to do. :(
