Hi Mathias,
I'm not sure about the matrix-transforms issue...
But
you can get selected items in roto/rotopaint nodes like this:
#####
import nuke.rotopaint as rp
ck =
nuke.toNode('RotoPaint19')['curves']
for i in ck.getSelected():
if
isinstance(i, rp.Layer):
print "layer ", i.name, " selected"
if
isinstance(i, rp.Stroke):
print "stroke ", i.name, "
selected"
