3D character style refers to a three-dimensional character visual system created through 3D modeling and rendering technologies, with diverse styles varying by scenarios and positioning. The realistic style restores real textures and light; the cartoon/anime style features simplified proportions and bright colors; the fantasy/sci-fi style integrates fictional elements; and the chibi style leans cute. Its core lies in designing shapes, materials, and colors to serve the expression of the worldview and help the audience immerse quickly.
