Maybe I'm approaching this problem from the wrong angle but I'm having trouble figuring out the best way to do this. I have a Python SOP inside of a digital asset. I'd like to push warnings from that Python SOP to the parent node so the artist can see the warnings at the top level of the digital asset rather than having them buried. The Houdini documentation suggests doing this which works on the Python SOP itself.
raise hou.NodeError("Invalid parameter settings")
How do I do something similar on the parent node (or potentially any random node)? I was looking for something like a generic node way to set a warning but I'm not finding it. How would you solve this? Thank you!
