I have found information on this topic of scene breaks available on the internet to be quite conflicting and I've frustrated myself into a lot of confusion. Some authors use only double spaces to indicate a scene break for a change in location, time, etc. Some authors use only asterisks. I've also found that some authors use both the soft scene breaks (double spacing) to indicate a change in location etc, and hard scene breaks (asterisks) to indicate a complete shift in the chapter.
Can someone please guide me on what is acceptable and what is the most preferred? Do editors change your formatting if they don't like it?
