A fact that normally baffles casual Star Wars fans is that all Clone Troopers in Attack of the Clones and Revenge of the Sith were CGI. But why? CGI would have been necessary for long shots large battle scenes, but during close-ups or with only a few characters onscreen? Besides, CGI wasn't exactly a shortcut, as the models for the clones were very complex and detail was astonishing. So that only begs the question; why were there no live-action clones? Even when Temuera Morrison's face was required, the rest of the body was CGI.
