If you are talking about the first cutting sequence, if you go to the start of the line with the scalpel, it will tell you what to do. And sorry about the sound issues, it was unfortunately added in the last second. Thanks for your rate!
Oh definitely get what you say, actually it was my first idea but I really couldn't get unity to do what I wanted. And there isn't really tutorials for what I wanted to do. This might be much to ask but if you know any tutorials for that I will gladly take it. ( I will check the Trauma Center as well)
