I'm trying to set all the weights on a skinned mesh to the same array
of values. When I run this script it doesn't change the weights.
Please let me know what my mistake is. Thank you!
import maya.OpenMaya as om
import maya.cmds as cmds
import maya.OpenMayaAnim as oma
om.MGlobal.clearSelectionList()
om.MGlobal.selectByName('skinCluster2')
sList = om.MSelectionList()
om.MGlobal.getActiveSelectionList(sList)
node2 = om.MObject()
sList.getDependNode( 0, node2)
skin2 = oma.MFnSkinCluster(node2)
skinPath2 = om.MDagPath()
index2 = 0
skin2.indexForOutputConnection(index2)
skin2.getPathAtIndex(index2,skinPath2)
geo2 = om.MItGeometry(skinPath2)
vertices = geo2.count()
for i in range(0, vertices):
ind = om.MIntArray()
nor = False
point = geo2.position(om.MSpace.kWorld)
doubleArray = om.MScriptUtil()
doubleArray.createFromList([0.4, 0.2, 0.1, 0.3], 4)
oldWgt = om.MDoubleArray()
newWgt = om.MDoubleArray(doubleArray.asDoublePtr(), 0)
print oldWgt
skin2.setWeights(skinPath2, component, ind, newWgt, nor, oldWgt)
