I did a basic breakdown of how a Sub D hero film asset will usually look, covering from topology all the way to naming convention and hierarchy. This is a just a general over view as things constantly change based on the task and even the studio, like one studio may prefer using 8k maps while others use 4 etc. There is no real set way to doing things so its best to ask around when you first get in to a studio, this is just aiming you in a good direction.
Comment If you have any questions or would like me to go further in to a specific area.
