@pr-boy I just installed map builder to see if I got a crash and I do crash with it in my game. I do think that is your issue as well. Also, I never recommend installing a mod using an OIV installer, too many things can go wrong if the mod author didn't do it properly and it makes it more difficult to uninstall unless you know what you are doing.

@pr-boy There is a small learning curve to using CW, but it is worth it. It is a lot easier to make things once you do get the hang of it. You can edit so much more stuff in CW, like I said you can edit vanilla mlo or addon mlo, scenarios, and a lot of other stuff I don't know about yet. I learned and still just use 3ds max and my brain to make my mlo and edit them, although I do use CW to place yft items into my mlos

Here is the link to the CW discord. You can get the latest release of it from the release channel, the version on gta5mod is not current. https://discord.gg/snSAPe

@pr-boy It isn't really that similar to Map Editor. You are kind of in the gta5 world when you place items, but not in the actual game, CW renders the world in. You can do soooo much more with CW though. You also have to know what you want to use, but that part isn't difficult, you can search for things in the included rpf explorer or you can search for vanilla entities (or props if you want to call them that) using OpenIV to get the names of things. You can directly make a ymap in CW so you don't have to convert a xml to ymap. And no, you don't need Map Builder to use CW. Map Builder is just more props used to make things in an incorrect way in my opinion. Making things like buildings or making terrain by putting together a bunch of props is not that great for game performance.

And to be honest, Map Editor is an outdated way to try to make things. I believe CodeWalker is a much better option for making edits or new ymaps for exterior mods. CW can also help make mlo or edit a mlo if you don't use 3ds max. And map builder is just more props, which you really don't need. Plus, don't try to make a ymap "interior" using either, because you will have issues like rain "inside" since the game only recognizes mlo as interiors.

@pr-boy I've been reading the comments in the Map Builder mod and there are a lot of people having crashes after installing it. I'm going to test this mod first to see if it crashes my game too.

@pr-boy Could be, I have never tried the Map Builder mod since I don't need it. I haven't even looked at the comments section for it to see if other people are having issues.

Either way, I know for a fact that ALL mlo mods do not cause crashes. But for you to not be able to have any at all without a crash, then it has to be an issue with one of those script mods. I'm leaning towards Single Player Apartment so I'm going to test that firs when I get a chance.

@pr-boy Hmm, then it must have a compatibility issue with one of them. I'll do some testing by adding each mod one at a time to my game and see what happens. But if you can't install any mlo, then one of them must have compatibility issues with all mlos, because I have a lot of mlo in my game made by myself and a few other people without issues.

You could test by removing one script mod and test until you find which one is having compatibility issues with all the mlo you want. Just depends on what you want more, a particular script mod or other mlo mods.

Plus when you say you tested vanilla, was that without those other mods you just listed as well or were they still in your game? Also, I'm not 100% sure but I don't think a mlo would have compatibility issues with a script mod. I remember having issues in the past with Single Player Apartment before I even made my mod.
