now i am confused....i have a new project where i plan on using carrara (4 or 5-have to decide) and poser (I have ver 5) I know very little about poser but my needs are very limited I expect to have a guy walking, looking, head and hand movement, very simple (with clothes)....so whats my best combo? carrara 4/poser 5 carrara 5/poser 6?
