On finished render callback issue

[anonymous_user_e4a25b09]

Hello,

Using your Python API, I would like to know what is the proper way of passing a callback function to an OnRenderMovieStopped object.
I wrote a python script that renders a level sequence, and pass in a function to run as a callback once the render is done. And I am puzzled why my callback does not kickoff when my rendering script is wrapped in a function (Otherwise, the callback runs well if you run the raw body of my function into the Output Log terminal). Please see my script in attachment below.

Thank you.

I stumbled upon the same issue with UE-4.25.4. Surprisingly, delegate works if I declare it in global scope (as in Engine/Plugins/MovieScene/SequencerScripting/Content/Python/sequencer_examples.py) but doesn’t work if I create it inside some function body. Very unpythonish behavior.

Think it is because the garbage collector will kill the callable unless it was declared as a startup object
