In this tutorial, we will construct a “fluffy universe” by combining a Physically Based Rendering (PBR) material workflow with procedural geometry driven by the Fractal operator. The process begins with the creation of a base 3D form, which is progressively refined through multiple deformation stages. These transformations include iterative shape distortion, secondary deformation passes, and the introduction of controlled twist operations. The Fractal SOP is then integrated to enhance surface complexity, requiring careful parameter management to avoid excessive geometric noise or instability.
