What materials did nick use to make wallice and gr-omit?

Nick Park, the creator of "Wallace & Gromit," primarily used plasticine clay to model the characters and sets. The figures were animated using stop-motion techniques, where each movement was captured frame by frame. The detailed sets often included various materials like wood, metal, and fabric to create a rich, tactile environment. This combination of materials contributed to the unique visual style and charm of the films.
