Base class for user-defined skin deformers.
MPxSkinCluster allows the creation of user-defined skin deformers. It derives from MPxGeometryFilter and so offers all the functionality of that class. Additionally, it has the per-vertex skin weights and other skin-related attributes of the Maya built-in skinCluster node.
Custom nodes derived from MPxSkinCluster are treated by Maya just like the built-in skinCluster, so all the weight painting/editing etc. tools that artists are used to also work on the custom nodes.

overridevirtual |
This method returns the type of the node.
This method should not be overridden by the user. It will return MPxNode::kSkinCluster.
Reimplemented from MPxGeometryFilter.
| float weightValue | ( | MDataBlock & | block, |
| unsigned int | multiIndex, | ||
| unsigned int | wtIndex | ||
| ) |
This method returns the weightValue stored in the datablock for the given geometry's lattice point/CV/vertex.
| [in] | block | the datablock for the node |
| [in] | multiIndex | the index corresponding to the geometry |
| [in] | wtIndex | the index corresponding to the component |
|
