what's needed is a 3d modeller & a metastream exporter. currently the only options available for mac users are poser (curious labs just posted an export plugin) and carrara. if there are any others options i'd like to know of them. if you're into flash, you might want to check out www.vecta3d.com & www.swift3d.com. these promise to be better than metastream but like so many others these days, mac versions are not out but due "soon" ... your last option is vrml, but the files can be enormous. i exported the same model in metastream & vrml and the metastream file was 250k while the vrml file was 7mb! if your want to see some examples of metastream files generated using the poser exporter, visit: www.aarrgghh.com/3dcharacters
