I have not tried that with multichannel exrs (which I guess you are
using) but nuke.layers(readNode) does work as expected here.
We do have an assembly that searches for footage then grabs all aovs (we
do have them seperate) and then depending in the available layers per
read some stuff gets attached... with backdrops in there.
Although I must admit I am setting each position, from every node via
setXYpos()....
and we create the channels via nuke.Layer(layerName, [red, green, blue])
prior to that.
I remember having problems with importing data into a camera and setting
it to not read from file...
I think I used nuke.show(camera) to get around this.... I think it was
complaining about a non existent knob...
Sometimes nuke.createNode did more what I was after instead of using
nuke.nodes.Node...
Maybe with 100 layers it needs to evaluate sth in-between to get all the
layers in ?

here is a part from the scene assembly that creates a subtract plus loop
of layers...
Would be nice to know if this works with multichannel reads...
Cheers

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):

Heya,
I am seeing quite a lot of issues with programmatically assembling
scripts. Anyone got any tips? Here’s
some of the issues:
- Creating nodes does not update their DAG position/size
values. So autobackdropping does not work because the screenWidth is not
available. You can force an update calling node.xpos() BUT this does not
work for NoOps.
- Creating reads works fine, but channels are not immediately
created it seems. When creating around 100 reads and piping them into a
zMerge and then trying to ChannelMerge a bunch of channels the channels
to be created by the reads are not available. They are created though
and it works if I run the script a second time in the same nuke-script.
- Creating channels via nuke.Layer does not really seem to
work. They are available in layer knobs, but not in channel knobs it
seems (?!?) Creating them via nuke.tcl works
This list probably should go on, but these are the most pressing issues
for me atm. Do I really have to precreate channels for reads (which can
be REALLY tricky)? And even then fall back to TCL to do so?
Cheers,
Thorsten
