That's OK.. Object inspector is exactly as its named. It's a tool for inspecting objects and finding out all sorts of info. Basically load up nords and open the sidebar menu. Then scroll down and look for dev tools (I think) and click on it. Once that opens you should see a new menu and you hold alt+left click on something - like a balloon or a tree or whatever and it will tell you the name and some other info about that object.YYou can then find that object in models.ini and remove it.
Just eating my dinner but shout if you need help and I'll assist when I've finished stuffing my face!
Many thanks for explanation ... i will try that app and see if i can find the kn5 files i need to remove. I will come back to you if i cant manage it. Enjoy your meal
