Maya now includes an updated and fully-integrated skinning tool set based on ngSkinTools. You get the complete layer-based system, advanced masking, and mirror tools directly in Maya.
Skin Tools introduces a new, non-destructive, layer-based approach to character skinning in Maya. This workflow makes it easier to refine, iterate, and solve complex deformations with greater control and confidence. See the Skin Tools overview to learn how this new paradigm improves both speed and quality in skinning workflows.
For a practical guide on how to use these tools in a production workflow, see the Skin Tools quickstart tutorial.
