Command Line rendering with Nuke and ComfyUI ?

[juergster]

Would like to be able to run the ComfyUI/Nuke workflows via a command line but am not an expert when it comes to trying to call anything other then a Write node. The Nuke script works as expected through the GUI.

Running the following command (on Linux):

Nuke14.0 -t render_test.py

The render_test.py script looks like this:

import nuke

nuke.scriptOpen('./Nuke_comfy_basic.nk')

nuke.toNode('QueuePrompt').setSelected(True)
group_node = nuke.toNode('QueuePrompt')

if group_node:
    force_animation = group_node.knob('force_animation').value()
    if force_animation:
        print("Force animation is enabled. Submitting animation...")
        comfyui.queue_prompt.animation_submit()
    else:
        print("Submitting regular request...")
        comfyui.queue_prompt.submit()
else:
    print("Group node 'QueuePrompt' not found!")

Not sure what I'm missing here. Getting this error:

Is running the comfyui.queue_prompt.submit() in the context of group_node? feels like we'd need to drill down from the nuke obj to the actual comfyUI instance/node from the loaded .nk
