Huolong, I assume you were replying to me rather than Mason. (Thanks btw to Mason & Lemurtek for clueing me in on the split-vertices to avoid smoothing thing.) Wavefront style .OBJ files are in fact ascii text files. To use the models from the ftp site I mentioned: -just download and save the .obj files to your hardrive (right-click on filename & "Save-Link-As"), -if there is a .MTL file with the same name, save that also. It will contain any UV texture mapping information for the .OBJ file. You don't have to do anything with it, just keep them together. -then, in Poser select File/Import/Wavefront OBJ/ and select the .obj file you downloaded. You will then get a bunch of check boxes to select importing options. You can leave them all blank, but you may want to check off the one that says something like "Make normals consistent", or somesuch. -You'll also have to fool around with the scale to get it the right size in Poser. When created in other programs, Obj files are usually scaled about a thousand percent too large for Poser models and rotated 90 degrees forward on the X axis. -After it is open, you can save it to your Poser library as you would a normal prop. The site also contains all the same models as .3DS and .DXF formats. The files look pretty old and it appears to have been a demo site for some file format conversion software. Hope something there helps.
