The Deformer add-on provides a workflow for modifying mesh geometry based on the proximity and influence radius of other objects. By setting a primary object and assigning up to 20 deformer objects, users can dynamically sculpt, carve, or indent surfaces. The add-on features two primary deformation modes: Standard, which calculates vectors between faces, and Normal, which utilizes the normals of the deformed faces. The tool includes controls for adjusting the influence range, strength multipliers, and normalization. It operates using Geometry Nodes under the hood and provides an interface for managing the deformation setups. Deformer objects must be mesh-based, as the calculations rely on vertex data.
