You have a 20 page multi-panel web comic offer and the client wants it ready in one week. You gonna use Maya or 3DS and build every single setting and detail and person in each scene and then suffer the posing of every character in every render with those slow bulky apps? Or are you gonna use Poser because almost every prop and person you need for the job has already been made and is EASILY poseable in Poser for extremely quick results? The usual argument of owners of expensive modelling apps is that Poser users use 'art' that was created by others. Did the Beatles build their own guitars? Did Michaleangelo build the chapel he painted? Did Fred Astaire build the stages he danced on? Did Bruce Lee (a martial artist) build the dojo he practiced in? Did the Maya and 3DS artists build their own Maya and 3DS applications?
