The plugin will import ANY OBJ file. Remember that while DS and Poser use the OBJ format,
it is Wavefront's native format, not Poser's. The only gripe I have with the plugin, is that it's 
export sucks wind. Unless they fixed that with tS 7. So the short answer is YES, if it is OBJ
format, the plugin will import it. :) The plugin will NOT do native Poser or DS files however.
