No, i don't mean rotating the faces. I can't understand exactly how could i change the direction of the edge loop flow! And the problem is theoretical - i need to keep quads and i need to change the edge loop direction exactly like on this video
What is happening there looks like magic.
Where can i read about the backstage of this proccess? Because when i try to do something like that manually, i stand two problems: 1. if i'm using to merge vertices it can produce me only 8-vertices sphere. 2. If i'm using knife, i always produce triangles and quads.
HOW DO THEY DO THAT
