Thanks! Yes, I felt this way as well. The trestle is actually a primitive boolean model with a material set with variable transparancy to make the rail support effect. At the time I was going to model one with real supports but something of that scale would have taken weeks. I'm still thinking of making one through, if I do, I will rerender and see how it tooks then. Thanks so much for taking a look and commenting!
I figured that's how you did it, and it did turn out surprisingly well. My husband modeled a trestle in Bryce quite a long time ago, it was very time consuming, but I think once you get the building elements, it probably goes pretty fast. Still, you really did a bang up job, it's a gorgeous scene!
