Rounding the sharp edges isn't a problem, but for some reason the rendering time for these pieces is much, much longer than for the original renders I did at the top and middle of this thread. If you could give me a hint on how to reduce the rendering times, I'd be happy to render a new batch.
I already minimized the number of lights and was using the same materials (with fewer parallel surfaces), so I'm puzzled.
