A scene created in P7 with V4, radiant jaguar hair, V4 boyshorts and sports top, the roadster, roadster light setup and the 'mansion' base and east wall.

I've recreated the scene saving out a new version as each element is introduced to see where (if it does it again) it falls over, though at the moment I'm rendering the completed scene just in case (it's taking a while). I'll post details of 'where' it falls over if it fails again.
