That affects all the frame I only want the stroke to be affected.
It works fine for me, but using this method you can’t share the same CC op to all your paint strokes which might be a huge problem, specially when rendering your workspace.
So you can do the following:
1.) Add a transparent solid
2.) Add the Paint op to this solid
3.) Set the Clone/Reveal source to your desired plate
4.) Apply the CC or whatever operator you like on this solid layer
You can also do this after you finished your cloning session on the desired plate by rewiring the inputs of the Paint op using the schematic view.
Just set your main input of the Paint OP to the Solid and your secondary Clone/Reveal Source input to the desired plate and then the output of the Paint OP to the Solid layer.
See ya!
