Hi!
I'm a student currently learning maya and doing a smaller project as part of my course work. I recently used cloud storage to take a maya project from the school computer to my own home computer, and it is acting very strange with selecting faces! And I don't know why?
I've attached a video to better show what I mean. (I tried looking at google, but nothing of what google said seems to have helped)
Any help would be very appreciated!
