stylized water whirlpool 3d model

Generate a 3D model of a stylized ocean whirlpool or vortex. **Key Features:** * **Shape:** Funnel-like, tapering downwards to simulate a deep, rotating water mass. The top should be wide and gradually narrow towards the bottom. The depth should be moderate, not excessively deep, suitable for a game environment. * **Topology:** Low-polygon count, optimized for mobile game performance. Prioritize clean, efficient mesh without unnecessary detail. * **Edges:** The top outer edges should be smooth and blend naturally, allowing for easy integration with a flat ocean surface. Avoid sharp, abrupt edges at the top. * **UV Mapping:** Crucially, the model must have clean, non-overlapping UV mapping. The UVs should be designed to support **radial texture rotation** (i.e., textures should appear to spin around the center when applied and rotated). * **Vertex Normals:** Smooth vertex normals for a seamless appearance, especially where it meets the ocean. * **Axis:** Oriented vertically (Y-axis up). * **Style:** Stylized,
