With your second point, about channels appearing from newly created Read
nodes:
We have a script which brings in several EXR's with one or more layers,
and combines them into one pipe using a bunch of Copy nodes.. and it
seems to work quite reliably (although never tried it with anywhere near
100 layers)
I was creating the nodes by doing this:
formatted = "%s %d-%d" % ("/example/path.%04d.exr", 1001, 1024) #
hardcoded example framerange etc.. usually calculated
r = nuke.nodes.Read()
r['file'].fromUserText(formatted)
Then querying the layers using:
for layer in nuke.layers(r):
