heyas; poser 3 and poser 4 people are both in poser 4. look in the people library and find the version 4 ones. if you dressed up your character with clothes and props, open that version 3 character, then replace it with the version 4 type. be sure you keep props attatched and all. if you have morphs on the head, you will have to transfer them over. prolly easiest to save them as a face file (unless you're using custom added morphs).
