Benjamin - I'm so glad you put in the that imports are OK on distant objects. I really need some curved support cables and tried multi-reping spheres along a path and while it looked good it took 400 spheres. That slowed the Bryce wireframe to a crawl. Modo made cables worked so much better!
Great start on your building and I really like this theme. Been a long time since I did a  mostly Bryce scene.
