Why would I need to press the 3 key? Are you proposing now that ALL models must be smoothed and built in anticipation of being deformed? No but I use the 3 key to look if there is some strange popping or irregular smoothing to fish out some problem area's. And regarding the last part yes I would consider the possibilty of a model being deformed in the proces, you see director's are a strange breed indeed ; At first they want to have a let's say a Battlestar Galactica Colonial Viper MKII just passing in front of a camera, before you know it he/she wants a heavily battered version in the shot " to show the audience that there really is a war going on out there" . And again I am not saying never ever use a NGon just use them with caution and sparingly that's all. Now why don't we just start modeling again instead of talking about ngons like some silly schoolgirls LOL
