that is some crazy *stuff* going on there! Any idea how they did it?

The light is just projected onto a 3d model > projected onto the real model.

There is so much work in these large physical models that they don't need any extra help with a lighting circus.


I built a third of this one. 1:2000 scale. It took 3 of us 4 months to build it. To a good level of detail for the scale. All by hand as well.

I don't know the hows or whys of light projection mapping but presumably there would exist a digital 3D model where all the elaborate light patterns are planned out and designed, I don't know how all the different planes of the model receive the correct light, multiple projectors? I've seen this on real buildings but doing a whole city (even a model) takes it to a new level of complexity.
