although curious labs does not support the poser pro pack's use of its lightwave 3d plugin (which allows lightwave to "host" poser files) with inspire 3d (lightwave 5.6 jr) and newtek claims that inspire's architecture does not support the opening of non-lightwave format scene files, a workaround does exist, using the mac's file exchange control panel to map the poser file extension .pz3 to inspire.

first install the lightwave plugin into inspire in the normal fashion and quit the program. then open the file exchange control panel. this control panel tells the mac os which mac programs to launch when double-clicking a non-mac document icon. while double-clicking the poser document still launches poser (is it, after all, still a mac document), if one attempts to open the file using a web browser, the browser, which is dependent on file exchange to tell it what to do with foreign files, will launch inspire, which will in turn open the poser file automatically. the imported file works normally within inspire as described in the pro pack pdf, with full access to the poser displacement plugin & its options.

i haven't tested it yet but i expect to get the same results by opening my browser preferences and explicitly mapping the .pz3 extension to inspire there.
