I am currently following the ‘how to model the female body’ tutorial series at Blender Cookie . com.
However, I do not know how the tutor adds a loop the eye ball that goes all the way around the UV sphere (360 degrees). When I do control R, the loop only goes less the half of the circumference.
The tutorial can be found here. He does the procedure at 25:54. However, it is not clear how he does it.
Otherwise, he is a great teacher.
