Everyone does realize that Poser 12 is still in Pre-Release and it is being updated at a fairly fast pace as more of these problems become known. While getting a Python script will be very helpful, Python itself was until recently still very buggy and most of those kinks have been worked out. Now they are working on the nodes so they work correctly and once that is done then they will probably work on the conversion scripts. But until those things are done making a fix today and have it broken tomorrow will led to even more porblems.
