Hi everyone,
how can I write values in the extra matrix of the transform of a roto or
rotopaint node?
I first tried to write it to the array knob which is showing the value. But
this does not work, as the array knob just shows the values that actually live
in the layers of the curves knob. Changes on the array knob don’t seem to be
propagated to the actual curves.
Hence, in a second attempt I tried to write the data as follows:
curves = rotoPaintNode['curves']
layer = curves.rootLayer
transform = layer.getTransform()
for i in range(0,4):
for j in range(0,4):
ac = transform.getExtraMatrixAnimCurve(i, j)
ac.removeAllKeys()
for (time,value) in animations[4*i+j]:
ac.addKey(time,value)
transform.setExtraMatrixAnimCurve(i, j, ac)
## here transform.getExtraMatrixAnimCurve(0,0).getNumberOfKeys() has all the
keys I’ve set
layer.setTransform(transform)
## here layer.getTransform().getExtraMatrixAnimCurve(0,0).getNumberOfKeys() has
0 keys...
As you can see from the comments, I can generate the AnimCTransform object for
the curve, but when I try to apply it with setTransform, nothing seems to
happen (no error message - the data I wrote is simply not there).
Any idea what goes wrong?
Extra question:
For my application, the user also needs to choose to which layer(s) the matrix
data is written. Is there any way to check which layers are selected?
Thanks a lot for the help!
