Hi,
I have run into problems getting nuke.Node.hasError() to work on nodes inside a
group. I have a solution, but it doesn’t seem very elegant and I’m wondering if
there’s a better way…
First, a general description of what I’m doing:
1) Get a list of all the source nodes in a script — Read, ReadGeo, etc. —
including nodes in any Groups…
2) Check the list of nodes for errors using the .hasError() method.
If I run my code in the Script Editor, all works as expected. I get the list of
nodes and can check them all, including those in groups. However, if I run the
code via a menu, the nodes inside the groups are not checked for errors.
To workaround this problem, I am doing this:
nodes_with_errors = []
for node in sourceNodes:
# Check to see if node is actually in a group and run .hasError()
method in that context...
if '.' in node.fullName():
node_group =
nuke.toNode('.'.join(node.fullName().split('.')[:-1]))
with node_group:
if node.hasError() == True:
nodes_with_errors.append(node)
# Node not in a group, so just check it for errors...
else:
if node.hasError() == True:
nodes_with_errors.append(node)
return nodes_with_errors
…Seems kinda ugly. When running code via a menu, is there a better way to take
a list of nodes that are both inside and outside of group nodes and operate on
them all in the same context…?
Thanks for any insights,
Rich
