Well, I take back my previous comment. Following along with this sculpting portion of the course is near impossible with 2.78! Like many others' question (still unanswered), WHY, when pulling with the Snake Hook, does it only select the front, even though Wireframe is enabled? This makes for a terrible beginning with a lopsided sculpt, even with X-Symmetry on. Also, the "Collapse Short Edges" is essential to follow Kent, but missing in 2.78. I thought Subdivide Collapse would work, with Relative Detail enabled, but it doesn't quite. Man, I was really looking forward to doing this course! Can someone please tell us how to fix these issues??
