Rigbits tweaks rig module

mgear.rigbits.tweaks.createJntTweak(mesh, jntParent, ctlParent)

Create a joint tweak

Parameters:
  • mesh (mesh) – The object to deform with the tweak
  • jntParent (dagNode) – The parent for the new joint
  • ctlParent (dagNode) – The parent for the control.
mgear.rigbits.tweaks.createMirrorRivetTweak(mesh, edgePair, name, parent=None, ctlParent=None, jntParent=None, color=[0, 0, 0], size=0.04, defSet=None, ctlSet=None, side=None, gearMulMatrix=True)

Create a tweak joint attached to the mesh using a rivet. The edge pair will be used to find the mirror position on the mesh

Parameters:
  • mesh (mesh) – The object to add the tweak
  • edgePair (pari list) – The edge pairt to create the rivet
  • name (str) – The name for the tweak
  • parent (None or dagNode, optional) – The parent for the tweak
  • ctlParent (None or dagNode, optional) – The parent for the tweak control
  • jntParent (None or dagNode, optional) – The parent for the joints
  • color (list, optional) – The color for the control
  • size (float, optional) – Size of the control
  • defSet (None or set, optional) – Deformer set to add the joints
  • ctlSet (None or set, optional) – the set to add the controls
  • side (None, str) – String to set the side. Valid values are L, R or C. If the side is not set or the value is not valid, the side will be set automatically based on the world position
  • gearMulMatrix (bool, optional) – If False will use Maya default multiply matrix node
Returns:

The tweak control
Return type:

PyNode
