I don't know about POLISURBAN, but URBANJUNK was made by entirely by me over the course of many weeks. Yes, it's inspired by NATIVE, but most definitely it's not NATIVE. These terrains shouldn't share even a single AI node, nor a single wall. The overall concept is also quite different.
You were warned about this two years ago with this specific terrain.
You have at least 13 examples on the attached image comparing the different levels NATIVEURBAN original terrain with your URBANJUNK, with the original NATIVEURBAN on the left and URBANJUNK on the right.
The screenshots were taken using MapView to compare the general appearance on the main window, the .RMP file nodes appear on top right box the and .MAP layout files on the bottom right box). Check how the positions of the nodes (top right) and the general layout (bottom right) is in many cases still the same.
I didn't bother to add all the compared files other than those 13 since to display them all would require close to a hundred screenshots. And since I made the original map layouts and AI nodes from zero, I know them like the back of my hand and recognize them immediately. And since I'm the original author of the .MAP/.RMP files, I'm the copyright owner of those since NATIVE was never a part of UFO2000 but my separate work.
NATIVE and its .MAP files were originally published around 2005 on my personal Geocities website, which can be accessed through the Wayback Machine here
https://web.archive.org/web/20140820064635/http://area51.xcomufo.com/, and I still have the website files available in my hard drive, which I have also attached to this post. I later adapted it to OXC by adding the .RMP files, so any claims that those files belong to the original game are delusional and an attempt to distract from the issue at hand.
You evidently added a couple new .MAP/.RMP files, have renamed the files, changed a few things and replaced some of the textures, but to claim that of these are all coincidence and URBANJUNK is all your original work is simply impossible.
And you don't ever credit the original terrain or me as author.
If people don't understand why I'm upset about this issue, check out the image and zipped file for yourselves and make your own conclusions.
PS - I've also attached the original POLIS terrain, also completely my original work, which Dioxine is also using after being told to remove it, and without even crediting me.
And Dioxine, since you mentioned this, I challenge you to go through my current BattleTech
mod and point me a single piece of content there that is your original work. Better yet, report it to the site and have my mod taken down since it's unauthorized content and Nexusmods is pretty heavy handed with those kind of infractions regarding permissions.
Unless you're claiming that adding pirates to a mod is a original idea of yours that no one has done before, and that ideas can be copyrighted, which then proves that you have no idea of what copyright is and how it works.
