Hi Mike,
You have the syntax a little off. The first argument to nuke.Layer is the
layer name. The second argument should be a list/tuple where each item is
<layer>.<channel name>
So, in your example, I'm not sure what's assigned to your variable
'read_node', but I'm guessing it's a node object, but should be a string. In
your list, you're not specifying which layer to add your channels to. That
would explain being able to see the layer in the viewer drop-down but not a
Copy node, which only shows you channels.
So, for example, if you want to add a layer called 'mylayer' and red, green,
blue and alpha channels to that layer, you'd do:
nuke.Layer('mylayer', ['mylayer.red', 'mylayer.green', 'mylayer.blue',
'mylayer.alpha'])
At first I was confused by this, too. I thought you could leave off the
layer name from each item in your tuple/list and nuke.Layer would assume the
layer in the first arg, but it looks like that's not the case.
