Ah! Yes. getProjectParam kept registering in my tired brain as strictly a value getter, not a parameter getter. So after I get the parameter, I’m free to get and set values.
But still, the broader issue for me is knowing what project parameters are available for me to access. Python’s built-in dir function obviously offers no help her. The whole reason why I was using NatronEngine.AppSettings.getParams() was to get a list of available parameters that I could get and set to. And I’m not seeing this in the documentation, although I haven’t read it from start to finish, so maybe it’s in there somewhere. And I’m still not entirely sure if NatronEngine.AppSettings.getParams() is broken or not as I’m not sure if I’m properly calling it (I think I am).
