it was a bit of a nailbaiting situation as the original model was short on nodes and 3DZ Studio destroyed the 1st original. The design had to be altered anyway to properly get the walls and the gangway around the main dome. It worked out nice though.
2 nodes to spare which will be put to good use.
Final step is sort out the mapping of the model which was also changed but that's just peanuts in comparison to designing it.
