The base structure of Pennywise was originally modeled using 3D Metaballs and Metaelements, rendered and, in a streamlined collaborative pipeline with Xavier Comas, subjected to digital painting and compositing to maximize the psychological impact of this ancient evil taking the shape of a clown, emerging from the light of the cover. The eye was one of those narrative elements, while the satisfied expression of Pennywise, almost looking at the viewer as if they were about to be his next feast completed the narrative.
