Animation of an object from a character modeling and/or animation tool is converted from a representation used by that tool to a representation used in a runtime animation system, such as a game engine. Such a tool typically represents the object using a source structure and a source skin. The runtime animation engine typically uses a target structure, target skin and shading to represent animation of an object. In addition to transferring motion of the object from its source structure to the target structure, deformation and shading also are converted. Low resolution information about the deformation of the source skin is converted into a set of skinning weights for associating the target skin with virtual bones added to the target structure and animated deformation data for each frame of animation. High resolution detail from the deformation of the source skin is converted into a set of normal maps, one or more masks and animated mask parameters for use by one or more shaders.
