I have an imagePlane node in which I am using an image sequence, say
myPicture.001.jpg - myPicture.030.jpg.
However, on the same imagePlane node, I have also set its Frame Offset
attribute with a value of -10, and so the image sequence will be starting
off at Frame 11 and ends at Frame 41.
As I would like the imagePlane to hold first and last frame (eg. if I
navigate to Frame 5, it will stays at myPicture.001.jpg, and if I navigate
to Frame 50, it will stays at myPicture.030.jpg). While I understand that
this 'holding' can be done with me removing the expression and sets a
keyframe at Frame 11 and Frame 41 respectively, but this is doable if I am
doing it manually within the scene.
My question here is how can I do this in a pythonic manner?
Initially, I tried to use
`cmds.getAttr("{0}.frameExtension".format(my_imagePlane))` in hopes that it
has a range of numbers and I can derive the first and last number from it.
but I was wrong..
As the field is still driven by expression, how can I determine Frame 11
and Frame 41 are the frames that I should keyed?
