I’m not sure what might be different on your end with my files but yours is having an issue due to the scale of the scene in relation to the units you are using, the settings for the displacement, the settings for the displacement texture, the render mesh for the trimmed surface being displaced and the intensity of the bump map in the material. All of these things work with one another so it’s some combination of settings and sizes here that is causing the bump to not be seen. I’m not having much luck hunting for the combination that would work at the current models scale but I can get it to work if I make the model much smaller and adjust all the things mentioned above.
You might want to try using Neon with the Brazil evaluation instead of Rhino Render. I think this combination of effects looks better with a Brazil Chrome material with a Noise texture in the bump channel. You’ll need to use the Brazil physical sky environment too.
I hope this helps some.
