The sculpture, originally only aesthetic was further developed with the idea that is also a functional piece of architecture.

Diegetically it would function as a cooling tower to support the large amount of cooling required within a high-tech cyberpunk world.

I used a high contrast image cityscape image and used its greyscale as an alpha to achieve transparency apart from a few point lights. Layering and staggering them to emulate distant city lights.

I attempted to use Niagara to create some smoke effects to fill the street. However, doing fluid simulated volumetric smoke, complete with collisions is very resource intensive and outside of my scope.

I fell back on a old school method of faking volumetric fog that is used in video games of using flat textures, set to pan onto spheres produced by an emitter to emulate the effect of smoke.
