Manually modifying the shape of game elements in 3D modeling software and reimporting them into the game engine is a frequent and time-consuming task in video game development. We present a tool for Unity that enables the extrusion of 2D shapes along Bézier curves through an intuitive graphical interface. Our approach allows users to define a 2D shape, compute its vertex positions along a concatenated cubic Bézier curve, and generate a triangulated mesh while ensuring C² continuity between segments. By integrating this workflow directly into the game engine, our tool eliminates the need for constant switching between external modeling software, significantly reducing development time and streamlining level design iterations.
