Thanks, so it sounds like it's not, at least not the way I had hoped. But further testing just now reveals a Utility script I assume ships with Poser. CollectSceneInventory.py can print a list of scene items with their full OS paths. In this test case, printed is:

      C:|.._blahblah_..|content|Runtime|Geometries|1971s|House on suburb|House.obj

It then seems like one might edit down this script to print out only the OBJ that has just been loaded (textureless) into the new scene. The script would then cut off the House.obj filename and in the path would switch...

      |Geometries|1971s| 

for

      |Libraries|Pose|

This, in 1971s's case at least, would then be a full working path for Explorer to open.
