What format are you looking for ? Poser can export to flash swf, that should be vector.
Haven’t tried it yet, though. I picked up Poser Debut a while ago for a bargain price, but hardly ever use it since i got DS.
Yeah, i don’t think realistic renders are an option. I suppose toon or stylized renders could actually be quite nice, you’d get an awesome amount of scalability and probably some nice options for postwork.
