Floating lips. Rebuild instead wires

Support
#1

Wires, used in Lips Rigger script, so bugged. Playing with dropoff, scale, rotate options did not fix wire lips.
This shit-script replace this wires with rebuild nodes.

Script:

import pymel.core as pm

def convert_wires_to_reba():
	#### for 2.xx ####
	'''
	xxx = [
	['lips_C_upCrv_ctlShape', 'lips_C_upperLipShape'],
	['lips_C_lowCrv_ctlShape', 'lips_C_lowerLipShape'],
	['lips_C_upCrv_ctlShape', 'lips_C_upRope_crvShape'],
	['lips_C_lowCrv_ctlShape', 'lips_C_lowRope_crvShape'],

	['lips_C_upCrv_upvShape', 'lips_C_upRope_upvShape'],

Hi Alexey,

Cool thanks for sharing! Iā€™m going to test this to learn what you did. Iā€™ve used rebuildCurve for ribbon effects before and it works well.

But in the meantime, the way I fixed my buggy lips was this. I mentioned wireDropoff in another thread, but I think this was mentioned somewhere else. The curves need to be constrained to the head space. (I have 2 head controls, so mine is ā€œhead_C1_0_jntā€. Default mGear might be ā€œhead_C0_0_jntā€)

This is, I believe everything I do, and this fixes my lips:

# Fix lip drift and flipping:
# 1. Set the corner lips constraint to "shortest" interpolation
for lipCtrl in pm.ls('lips_L_corner_ctl', 'lips_R_corner_ctl'):
    lipCons = list(set(lipCtrl.getParent().inputs(type='parentConstraint')))[0]
    print lipCons.interpType.set(2) # shortest
# 2. Constrain lips_C_crvs to the head space
headJoint = pm.PyNode('head_C1_0_jnt')
lipCurvesGrp = pm.PyNode('lips_C_crvs')
pm.parentConstraint(headJoint, lipCurvesGrp, mo=True)
pm.scaleConstraint(headJoint, lipCurvesGrp, mo=True)

# a hack or solution? Mouth wires don't follow rig 100% unless you crank up the dropoffDistance.
# So when the character moves large distances, the mouth slowly begins to collapse.
for each in pm.ls(type='wire'):
    each.dropoffDistance[0].set(100)
