Lol Ken. Ok, understand that I was where you were when I worked it out. I did so many trial and error runs that I don’t really remember them all, which worked and which didn’t.
I remember I ran the setup from “Run” in windows. That generates a whole lot of .pyc files (the brown ones). Then you load the file with your basic scene in it (rename it because it will be saved under that name). In the text editor (because I havn’t put them in my Script folder yet) load the 4 .py files that start with “Blender”. Select the "Export one and run it. That saves it to the current directory. Import it with the relevant script and run “BlenderPCD.py” (maybe BlenderPYC imports it? can’t remember). That’s as far as I’ve got. I’m still trying to find out how to access the windows, doors etc.
