I have been working on revising my first novel. It is currently written in 3rd person multiple following the five main characters and the two antagonists. Each scene is written in 3rd person limited following one character, however there are several scenes within a chapter. What is the proper way to distinguish when there is a character shift? I was currently putting a blank line, two centered asterisks, and then another blank line to break them up. I am wondering if there is a standard for this kind of stuff, or if I should do away with the breaks all together and just let the reader figure out that the perspective has changed. I tried to do a little research on the subject via google but came up with very little so I thought I would ask the more experienced. I appreciate any help you can be.
