Cross-posting to the Python list, just in case it's more appropriate.
How do you create and initialize a BlinkScript node from Python?
The following function is my work in progress.
def createBlinkScriptNode( blinkScriptPath, inputs ):
blinkNode = nuke.nodes.BlinkScript()
blinkNode['kernelSourceFile'].setValue( blinkScriptPath )
nuke.show(blinkNode)
blinkNode['clearKernelSource'].execute()
blinkNode['reloadKernelSourceFile'].execute()
for i in range(len(inputs)):
blinkNode.setInput(i, inputs[i])
return blinkNode
This does the job when working interactively but is problematic when
working in batch. Without the 'nuke.show()' call in the middle of the
function, the subsequent clear kernel and reload kernel calls don't have
any affect when running interactively. That probably has something to do
with why we're seeing problems in batch too.
Without the UI update that you get interactively, the batch version of the
node doesn't know how many inputs it should have or understand what kernel
parameters should be exposed for the given 'kernelSourceFile'.
Thanks again for your help,
