The visual effects were primarily provided by Weta Digital . Effects supervisor Erik Winquist and a small crew travelled to Chicago to create a model of the Chicago Loop that would be destroyed in the climactic battle , learning the building materials and architecture styles . Up to 15,000 photographs were taken with 3D scanners , while motion cameras covered downtown Chicago . As reference for the building destruction , the artists studied both the World Trade Center attacks and implosions of buildings affected by the 2016 Kaikoura earthquake in Weta 's hometown of Wellington . One of the more challenging aspects for Weta was figuring out how the weight and mass of the monsters would affect the city environment and destruction
