I briefly talk about the issue in my First video in the Poser2Blender2Poser series on youtube.

Poser2Blender2Poser The correct import and export settings

The issue about the unwelding of vertex groups at obj file save is shown here in Video4 of the series.

Poser2Blender2Poser : Why you have to delete the Poser saved obj files

@ TheDarksideOfArt

I look at and handle a lot of end users issues and most of them can be traced back to the quality of the obj file. Lost vertex, unwelded parts, you name it, I have seen it. Pockets or buttons or belts that are thrown on, welded only to God, improper clean-up after the creator changed his mind, all passed and where released over time because "it worked".

Then comes some guy that wants to create a morph, or wants to do a "refit", and the whole thing comes apart. Tja, unwelded parts don't follow and weld cracks all over the place.

Lost vertex are very common too. And they are not so easy to handle because as we all know : Once finished and rigged, one has to mantain vertex order.

The issue we are talking about here are the double vertex at all welds between the vertex groups. => See Video4: Why you have to delete the Poser saved obj files.

Poser is a very solid app. Most end users issues can be traced back to the quality of the obj files.
