Take a look on this snipped below, I created it offset shape's opacity
keyframes.
*****
import nuke, nuke.rotopaint as rp
def rptsw_walker(obj, list):
for i in obj:
x = i.getAttributes()
if isinstance(i, nuke.rotopaint.Shape):
list.append([i, obj])
if isinstance(i, nuke.rotopaint.Layer):
list.append([i, obj])
rptsw_walker(i, list)
return list
def Offset_Opacity():
rotoNode = nuke.selectedNode()
rptsw_shapeList = []
if rotoNode.Class() not in ('Roto', 'RotoPaint'):
if nuke.GUI:
nuke.message( 'Unsupported node type. Selected Node must be
Roto or RotoPaint' )
raise TypeError, 'Unsupported node type. Selected Node must be
Roto or RotoPaint'
fRange = nuke.getInput('Inform the Opacity offset (ie: 10 or -50)',
'0' )
fRange = int(fRange)
rotoCurve = rotoNode['curves']
rotoRoot = rotoCurve.rootLayer
rptsw_shapeList = rptsw_walker(rotoRoot, rptsw_shapeList)
for shape in rptsw_shapeList:
if isinstance(shape[0], nuke.rotopaint.Shape):
count = 0
shapeattr = shape[0].getAttributes()
opacityCurve = shapeattr.getCurve("opc")
opacity_keys = shapeattr.getNumberOfKeys("opc")
store = []
while count < opacity_keys:
op_keytime = shapeattr.getKeyTime(9, count) #9 is the
index of opacity attrib
store.append([op_keytime,shapeattr.getValue(op_keytime,
"opc")])
count +=1
shapeattr.removeKeys(9)
for key in store:
shapeattr.addKey(key[0]-(fRange*-1), "opc", key[1])
rotoCurve.changed()
rptsw_shapeList = []
#remove the line below if you are using the script with menu.py (in
menus/DAG/etc)
Offset_Opacity()
Hey all,
I'm trying to access the data connected to a shape in the RotoPaint Node.
from my understanding I can get to the shape-object like this :
node = nuke.selectedNode()
nodeCurves = node['curves']
shape = nodeCurves.toElement('Bezier1')
print shape
my question is :
is there a way to access the information of this shape-object such as
motion blur ( if it's on or off ) or keyframe position ( how >many frame
? on which frame there are Keys ?) lifetime of the shape, and, if it's
possible, how to change them by code ?
thanks in advance
Marco
