A .pmd file is a system for storing morph data externally from a .cr2, it was introduced with Poser 6. The intention of .pmd files is to reduce the file footprint of characters with a lot of morphs and also reduce loading times for said characters. You may toggle Poser's use of .pmd via preferences/use external binary morph targets. Up until poser 8, using the .pmd system had a chance of causing scene corruption... Apparently all of the bugs have been ironed out but people are still pretty skittish about using it. there's a rather simple method for creating various morph injection poses via the .pmd system. It's not possible to edit a .pmd file with a standard text editor as you may with most Poser files.

That's the long story short version of .pmd, Most of the old timers round here will probably tell you not to use it and to turn it off in prefs. I personally don't use .pmd unless I'm going to create an INJ, and then only long enough to generate the necessary file. If you are using .pmd make sure to keep the file where Poser will look for it relative to your .pz3 or .cr2.

A good concise description.  Certainly makes me an old timer as I never use external binary morphs as, although it is stated that all the problems are fixed, I have lost too many files due to corruption to really trust using them.   I know some people have said they now use them without problems but for me it is a case of once bitten, twice shy.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
