This is a warp deformer for internal anatomy such as tissues and fascias. It can also warp Maya joints and locators that you may be using to Maya-rig your creatures. This deformer can warp Maya meshes, NURBS surfaces and curves, joints and locators. This deformer solves a harmonic problem in the domain enclosed by the source cage, mapping the source cage onto the target cage, and as such maximizes the smoothness of the warp. The source and target cage meshes must have the same number of vertices and same mesh connectivity. For more details, see Harmonic warp (polygonal meshes, NURBS curves and surfaces, joints, locators).

This node can be created with the zHarmonicWarp command.

Attribute Meaning
envelope Interpolates between no effect (0) and full effect (1). Note that the standard deformer weights can be painted and they multiply the envelope.
recompute When on, the node automatically recomputes whenever an input changes. When off, the node does not recompute. Useful if you need to adjust a few parameters and you don’t want the node to recompute after each individual change.
tetSize The tet mesh size for the harmonic warp, in scene units. No tets will be larger than this value.
maxResolution Interrupts the computation if the smallest tet would divide the object into more than this many tets per side. For example, if maxResolution=100, then the tet meshing will abort if the tets will be smaller than 1% of the width of the object. This does not affect the result (assuming the computation was not interrupted). This usage is the same as in the zTet node. It exists to guard against crashing the tet mesher if tetSize is set to a tiny value.
surfacePenalty Controls the tradeoff between the smoothness of the output, and how precisely the warp obeys the target cage. This value is given on a log scale, and can be negative, zero or positive. Smaller values increase the smoothness at the cost of the warp deviating more from the target cage.
showTetMesh Turns the display of the tet mesh on/off.
