When working with mbFeatherTools, sometimes you need to change the mesh after applying feathers. The problem with this is that the deformed mesh needs to have the same vertex order as the reference mesh. This example shows how to apply a subdivision to an existing feather system. The key is to modify both meshes the same way, and to pull the new operators into the right position in the operator stack. On the reference mesh, the operator needs to be evaluated before the mb_FeatherInitialize operator.
