The invention provides a 3D model automatic style
conversion method and device, equipment and a medium, and the method comprises the steps: building a reference texture
training set of a reference game model according to a UV map of the reference game model, dividing the reference texture
training set into a plurality of different regions, and filling the different regions with color blocks of different colors; applying the reference texture
training set to UV coordinates of the reference game model to generate a 3D model of the reference game, and generating a reference matching training set from the 3D model of the reference game; for the color blocks of each area, pre-generating a target texture training set of the game model to be converted, applying the target texture training set to UV coordinates of the game model to be converted to generate a 3D model of a game to be converted, and generating a target matching training set from the 3D model of the game to be converted; and reducing the area of the division region of the reference texture training set, and repeatedly executing the steps until a target texture training set of a required style is obtained. According to the invention, manual construction is not needed, and an automatic style conversion
algorithm can be realized.
