sigh..unfortunately I am not versed in python at ALL. But I suppose I could snoop around and see what I can figure out. When you say engine.py, are you referring to the file called "octane.py"? Because I do not see an actual .py file anywhere that is actually labeled "engine.py", unless maybe I am looking in the wrong location? I am looking inside my blender scripts in the folder called octanerender. Also, I am looking at the .py files in the blender text editor, just in case you were wondering lol.
