Abstract: Diversity appearance of character can create a realistic effect. It is an effective way to resolve the difference of the character appearance in crowd simulation scenarios by strengthening the diversity appearance of characters with texture. This paper puts forward a method to achieve diversification of the appearance by texture templates. First, UV is unfolded for the mesh model without texture coordinates as texture templates. Second, the texture templates are processed to get the semantic information of clothing based on image segmentation. Finally, the texture templates are filled with pure color or image tiles, and various textures can be gotten to achieve the goal of diversity appearances in crowd simulation. The proposed method is practical and feasible to solve creation efficiency issues of virtual character, and can quickly generate visually-convincing large-crowd simulation results.#br# Key words: texture; UV; diversification; crowd simulation
