If this is the Atlantis gate room in the freestuff then forget what I posted in my other post, a couple of the .OBJ aren't right and either aren't loading any mesh or are crashing, and not just in DS, the OBJ08_transporter.obj crashed Hexagon.

Checking a couple of the files in a text editor shows that there is garbage in them, not sure if the garbage has deleted any of the polygon data from some of the bad files, but it's mangled the data for roughly 20 polygons in OBJ08_transporter.obj, and it's that mangled data that's causing the crashes.

Knowing Poser's mesh handling system it hasn't even seen the garbage, and loaded the mesh minus any missing polygons, however even it wont have liked the mangled polygon data in OBJ08_transporter.obj, and will have either not loaded the mesh or only loaded part of it.
