I accidentally deleted
component = geo2.component()
I do mean to iterate through the geometry. I want it to go through
each vertex and set the weights to [0.4, 0.2, 0.1, 0.3]
It still doesn't do anything when I change it to
while not geo2.isDone():
ind = om.MIntArray()
nor = False
component = geo2.currentItem()
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)
skin2.setWeights(skinPath2, component, ind, newWgt, nor, oldWgt)
geo2.next()
What am I writing wrong?
