I built all the structures in my failed competition level with "segment-like" entities. It made it much easier to build in the level rather than building them outside Reloaded and then getting them to fit into the terrain. Stacking them was a huge challenge, though. There's a catch in doing this, though: It taxes the engine since poly count and draw calls go through the roof! Beta 1.0071 seemed to fix that and my frame rate shot back up, but it brought another issue, at least for me. I'm hoping 1.008 will solve my issue.
