Actions and modifiers define how you manipulate geometry with ZModeler. Actions apply direct changes to polygons, edges, points, and curves, while modifiers refine how these actions behave, allowing for more precise and customizable transformations. Together, they provide a powerful and flexible workflow for modeling.
For a beginner user, understanding the distinction between actions and modifiers is key:
Actions initiate transformations such as extruding, bridging, beveling, or aligning components. Each category—polygons, edges, points, and curves—has a unique set of actions to modify specific geometry types.
Modifiers adjust the behavior of actions, fine-tuning their effect to achieve more controlled results. These settings influence symmetry, alignment, curvature, and dynamic interactions, making modifications more efficient and predictable.
Modifiers appear alongside their corresponding Actions, ensuring users can tailor each transformation to suit their modeling needs, whether refining edge loops, repositioning points, or shaping surfaces with curves; combining Actions and Modifiers allows for precise, efficient, and intuitive modeling in ZBrush.
