Problem summary:
Format objects returned by node.format() cannot be used to set the format knob
Customer reported version:
Nuke 13.2v7
Customer reported platform:
Windows 10
Steps to reproduce:
1) Launch Nuke and create a CheckerBoard node in the Node Graph.
2) Open the Script Editor window and run the following code:
format = nuke.toNode("CheckerBoard1").format() nuke.root()["format"].setValue(format)
3) Observe the warning that appears: Root.format format {...} not in named format list
Expected behavior:
Using setValue() on the Root format should succeed when passing a Format object returned by node.format().
Actual behavior:
Format objects returned by node.format() raise a "format not in named format list" warning when attempting to setValue() on the format knob.
Workaround:
Instead of using node.format(), any of the following options should allow the Root format to be set correctly and without a warning, but this only works if the node has a format knob, and the last workaround only works if the format has a name:
format = nuke.toNode("CheckerBoard1")["format"].value()nuke.root()["format"].setValue(format)#----------------------------------------format = nuke.toNode("CheckerBoard1")["format"].actualValue()nuke.root()["format"].setValue(format)#----------------------------------------formatName = nuke.toNode("CheckerBoard1").format().name()nuke.root()["format"].setValue(formatName)
