I'm following a course from CGCookie (Basics of character modelling). I'm trying to pull one of the vertices backwards:
there's a mirror modifier on, as well as skin and subsurf.
All the geometry gets warped:
Same thing happens when I'm trying to extrude another vertex from the bottom one.
Can anyone please help? I tried asking the question on the course's page, but the mods deleted it for some reason.
