Techniques are disclosed for creating and customizing graphical models. In one embodiment, a design application receives a morphological attractor created from the same mesh as one or more inheritance-based character generation ancestor models. Upon receiving the morphological attractor, the design application may use the attractor to align and transform the ancestor models to create a new set of ancestor models which resemble the attractor. The new set of ancestor models is referred to herein as being in the “genetic space” of the attractor. A user may then create child character models in this same genetic space by, globally or locally, blending two or more of the new ancestor models.
