Map processing and game material generation method and device

The invention discloses a chartlet processing and game material generation method and device. The map processing method comprises the following steps: acquiring a model of each object in to-be-merged objects and a map corresponding to the model; obtaining target models meeting a preset precision condition from the models, and synthesizing the target models into a first model group; performing UV expansion on the first model group to obtain UV data of the first model group; baking the chartlet according to the first model group UV data to obtain a combined chartlet and second model group UV data corresponding to the combined chartlet; wherein the merged map comprises a map of each object, and the UV data of the second model group are new UV data. According to the game material generation method, the combined chartlet and the corresponding model are adopted to generate game materials. By adopting the method, the problem that the precision of each model is reduced after the chartlets are merged is solved, and th
