how does the map builder affect the game?
I wanted to add it to my game but I'm afraid of breaking something. I was even thinking of creating another mod folder to test, but I'm practically without free space on my pc.
@Niziul Unless it writes to or modifies files it is impossible for it to impact your game. However, if it installs with an OIV it can definitely impact and break things.
OIVs often replace your dlclist.xml and your gameconfig.xml, but they can also modify other files as well - and they can't be uninstalled automatically.
I don't know map builder, but if it is an OIV, then unzip it and check the file called assembly.xml and the folder called contents. If it is a manual install, you will have full knowledge of what you changed - allowing you to backup selectively.
If you are serious about map building, check out CodeWalker, much more professional and powerful.
