controlShape is a Maya shape node that can be attached to whole meshes or their faces.

- Static and dynamic meshes.
- Scale by a normal.
- Color and opacity control.
Compile the plugin for the Maya version you want using Visual Studio. No dependencies required.
Use the following code to create or parent controlShapes.
import pymel.core as pm def makeControlShape(): ls = pm.ls(sl=True) faces = pm.ls(sl=True, fl=True, type="float3") sh = pm.createNode("controlShape") if faces: mesh = faces[0].node() mesh.outMesh >> sh.mesh sh.meshInWorldSpace.set(True) indices = [f.index() for f in faces] sh.meshFaces.set(indices, type="Int32Array") sh.meshMatrix.set(mesh.getParent().wm.get()) elif ls: pm.connectAttr(ls[0].outMesh, sh.mesh) pm.disconnectAttr(ls[0].outMesh, sh.mesh) sh.getParent().setMatrix(ls[0].wm.get()) def parentControlShape(): ls = pm.ls(sl=True) if ls and len(ls) == 2: controlShape, control = ls for sh in controlShape.listRelatives(s=True, type="controlShape"): pm.parent(sh, control, r=True, s=True) sh.rename(control+"Shape") if not sh.meshInWorldSpace.get(): sh.meshMatrix.set(controlShape.getMatrix() * control.wim.get()) pm.delete(controlShape) else: pm.warning("Select controlShape and transform") #makeControlShape() # select mesh/mesh faces #parentControlShape() # select controlShape transform and a control you want to parent to.
makeControlShape can be applied to both whole meshes and mesh faces. In the first case there will be a static mesh control created. The second one case creates a dynamic deformable shape control.
