thanks Chad!
you are my api-savvy doppleganger.
so, everything is working... almost. the problem i'm having now is
with evaluation.
if i connect the two arrays directly to each other, then the
blendshape is not updated as inputs to my node change.
from pymel import *
at1 = PyNode('sppl_ColorAtPointNode1.weightsList[0].weights')
at2 =
PyNode('blendShape2.inputTarget[0].inputTargetGroup[0].targetWeights')
at1 >> at2 # connect the two array parents
all of my node's inputs are set to affect both weightList and weights:
plColorAtPoint.attributeAffects(plColorAtPoint.time,
plColorAtPoint.weightsList)
plColorAtPoint.attributeAffects(plColorAtPoint.inColor,
plColorAtPoint.weightsList)
plColorAtPoint.attributeAffects(plColorAtPoint.useSG,
plColorAtPoint.weightsList)
plColorAtPoint.attributeAffects(plColorAtPoint.inSG,
plColorAtPoint.weightsList)
plColorAtPoint.attributeAffects(plColorAtPoint.inMesh,
plColorAtPoint.weightsList)
plColorAtPoint.attributeAffects(plColorAtPoint.eyeToWorld,
plColorAtPoint.weightsList)
plColorAtPoint.attributeAffects(plColorAtPoint.time,
plColorAtPoint.weights)
plColorAtPoint.attributeAffects(plColorAtPoint.inColor,
plColorAtPoint.weights)
plColorAtPoint.attributeAffects(plColorAtPoint.useSG,
plColorAtPoint.weights)
plColorAtPoint.attributeAffects(plColorAtPoint.inSG,
plColorAtPoint.weights)
plColorAtPoint.attributeAffects(plColorAtPoint.inMesh,
plColorAtPoint.weights)
plColorAtPoint.attributeAffects(plColorAtPoint.eyeToWorld,
plColorAtPoint.weights)
but no matter how i much i change these inputs, nothing changes on my
blendshape. even if i force my node to evaluate, the blendshape still
does not change. but if i connect each individual element from my
custom node to the blendshape weights, everything evaluates as
expected:
from pymel import *
at1 = PyNode('sppl_ColorAtPointNode1.weightsList[0].weights')
at2 =
PyNode('blendShape2.inputTarget[0].inputTargetGroup[0].targetWeights')
for i in range(at1.size()): # cylce through and connect each element
at1[i] >> at2[i]
it's not really so bad to do it this way, but i'm a bit concerned
about load/save and general performance with high resolution meshes.
my intuition tells me that it might be faster if i connect the arrays
at their parent instead of at each element. is this not the case, not
possible, or am i just coding my node wrong?
thanks again,
chad
