Attached is a WIP that I have been piddling with for some time. Everything was normal until I added that lovely little bus-stop on the right. The bus-stop triples the render time. The anti-aliasing pass took 3 hours to get from 56% done to 57% done. There is some material complexity in the bus-stop, but nothing like volume or such render-time sinks. I am not sure what is going on here. I am very fond of the bus-stop and don't want to omit it. Has anyone ever had a render time triple with the addition of one element, and a small one at that? Peej
