Yeah I had to define my narrator's text as a character, and I set the character name to None so no name appears over the text. So yours would look like:
define vo = Character(None, color = "#6699cc", ctc = "ctc_anchored", ctc_position = "fixed")
At least that's how I did it. I’m really poor at programming so if that doesn't work you may want to try the lemmasoft forums.
Many thanks if you'd like to contribute! Every small bit helps. I think the best way to give would be the Part One art book because you get something in return. But for a simple straight donation I have a ko-fi tip jar.
