Some real fences bend sharply as well. I have no idea if the specific ones they are supposed to be did. Either way, I were mostly concentrating on the last pic anyway.

Are the renders made using raytracing? They seem a little speckled in places, notably the reflections.

I use V-Ray. I think the speckling is caused by subpar image sampler settings in addition to the Catmull-Rom edge enhancement filter that I'm using. This is the first project I've worked on with V-Ray, so I'm still learning how the various settings influence renders.

Ahhhh, don't look too closely at the lobby render! I hadn't refined the spline pathing for the rails when I took that snapshot, which is why the edges are too sharp. The material also looks like shiny plastic rather than metal. I was going to add a few more renders but I'm having trouble with V-Ray's licensing system after a reinstall and I'm waiting for support to answer my inquiries...

Hmm... Ok, found one: usually, there are small imperfections in the smoothness of windows that give ever so subtle distortions of the reflections at very large scales.

Hmm, how would you go about simulating that? Tiny flecks of scattered noise in the glass material's reflection map?

It's usually due to small, gradual variations in the refractive index of glass (due to strain or difference in composition) or due to minute differences in the thickness of the glass. Eithr could be modeled with perlin noise, but in either case it may cause your render time to explode.

I bet somebody is going to build this in DF and connect the bottom pillars to a lever and...

I'd say doing it in geometry would be the most accurate, just rotate or skew each window pane randomly by some tiny amount. That is assuming you have the panes as separate objects rather than just a single plane for the entire wall. It IS on the pane level thou, a noise function that ignores that is probably worse than just having it flat like now.

Hi mikefictiti0us

I was wondering if you have finished the model of the WTC and if you would be interested in selling it.

Thanks
