A computer-implemented method comprising: identifying, by a processor, a representation of a feature of an animated character by inverting a skinned representation of the feature in a first position and subtracting a representation of the feature in the first position from the inverted skinned representation of the feature in the first position, wherein the inversion includes a non-linear inversion of the skinned representation of the feature; and skinning the identified feature representation to produce the animated character in a second position.
