Step one: Create your external dummy runtime.
Step two: Link to in in Poser.
Step Three: Save your Pig/Hog to the figure portion of that dummy runtime as a CR2 (Character File)
Step Four: Open the CR2 and veryfy that all file calls are relative and not absolute. Edit any Absolutes and change them to relative. The CR2 will contain your morphs unless you have external binary morphs turned on. I suggest turning it on and creating the PMD morph data file and then learning how to create a PMD Injection PZ2 file.

I probably left a few steps out but you get the general idea. PZ3's haven't been used to distribute characters since Poser 3/4 that I know of. I'm sure someone will come along and correct any errors I posted and will probably tell you I'm completely wrong, but that's just the way things go around here.
