1. A method for integrating an external three-dimensional character into a character creation system, comprising: importing a three-dimensional model of a character, the three-dimensional model comprising a three-dimensional character mesh having a plurality of vertices, wherein the three-dimensional character mesh is created by a system that is external to the character creation system; identifying, by at least one processor, a vertex of the three-dimensional character mesh that does not have a one-to-one match with a vertex of a predefined three-dimensional template mesh based on the three-dimensional character mesh being created by the system that is external to the character creation system; identifying, based on the vertex of the three-dimensional character mesh not having the one-to-one match with a vertex of a predefined three-dimensional template mesh, a plurality of related vertices within the predefined three-dimensional template mesh; determining, for the vertex of the three-dimensional character mesh not having the one-to-one match with a vertex of the predefined three-dimensional template mesh, a correspondence value based on the plurality of related vertices from the predefined three-dimensional template mesh; associating the correspondence value with the vertex of the three-dimensional character mesh not having the one-to-one match with a vertex of the predefined three-dimensional template mesh; and rigging the three-dimensional model of the character based on leveraging the correspondence value associated with the vertex of the predefined three-dimensional template mesh.
