Well, the question has been posted to E-on's tech support; I'm satisfied that no two configs are the same, and they bomb with an access violation just after they start to render a frame. Sounds suspiciously like they may have used an incorrect build of the Cow for the gold master again, like they did with the release of VuePro. However, -Mover 5- works just fine; cloth dynamics import and work properly, and I'm working on a 'strain the system' test scene to throw at the garden when it works (V3, RDNA's Beast Hunter outfit, the skybike, a scaled up grid of Dystopia city blocks with some tweaking of materials a-la Helgard ne. Numanoid, and some serious windforce on the dynamic hair. And since they have a working OpenGL implementation in V5, the issues created by that seem to be no more.
