Vieuxcrest World Mod | Installation Instructions

My world mod packs have two distinct components: Areas and Mods.
You can just install the mods/cc if you only want the custom objects. The world replacement files are optional. But I highly recommend them for the best experience!

MODS (Mostly Base-Game Compatible)

  • Download & Extract/Unzip the .zip folder.

  • Download the most recent version of "[Lijoue]BuyFood" and move it directly to your Sims 4 "Mods" folder. (This is a core mod that is required for many of my functional food/ shopping related objects.)

  • Move the "Vieuxcrest Mods" folder directly to your Sims 4 "Mods" folder.

  • Feel free to delete anything you're not interested in, but pay attention to the corresponding "tuning" files.

AREAS (Base Game — Newcrest)

THIS IS THE SLIGHTLY HARDER PART SO PLEASE READ CAREFULLY.

  • The mod folder "Vieuxcrest Areas" contains three .world override files: "BG_Engagement_01" and "BG_Engagement_02" and "BG_Engagement_03".

  • These are override replacement files that must replace all the original .world files with the exact same names.

  • You must find the original files and replace them with the mod versions.

  • You may be able to find them by searching directly in your file browser, but it's usually better to find the folder manually to avoid mistakes. (example paths below)

  • The exact location(s) of the folder(s) may vary slightly depending on your computer and game launcher or if 🏴‍☠️.

Example file paths:

WINDOWS PC:

  • This PC > Windows(C:) > Program Files > EA Games > The Sims 4 > Data > Worlds > Areas

  • This PC > Windows(C:) > Program Files > Electronic Arts > The Sims 4 > Data > Shared > Worlds > Areas

  • C:\Program Files (x86)\Origin Games\The Sims 4\Data\Shared\Worlds\Areas

MAC:

  •  In the ‘Applications’ folder, right click the ‘The Sims 4’ app icon and select "show package contents" to access the game folder.

  • Applications / The Sims 4 / Contents / Data / Shared/ Worlds / Areas

STEAM DECK:

  • Open dolphin file browser in desktop mode. Make sure "show hidden files" is selected in the browser settings

  • / > home > deck > .local > share > Steam > steamapps > common > The Sims 4 > data > Shared > Worlds > Areas

How to Check If It Worked

A quick and easy way to see if the world mod was installed correctly is to load into a lot (in build mode or live mode) and zoom out to see the surrounding "off lot" area. In Lagon Port, you should see the giant Ferris wheel by the water. In Vupont, you can see the playground equipment in the park area. In La Crête, you can see new buildings like a church building on one side of the street, and the dépanneur on the other end.

EXTRA INFO

  • Back up your original .world files and save files, just in case.

  • Clear your game cache whenever you add/update mods. This guide is great!

  • Because the .world files are replacements, it's not possible to use other .world files with the same name (such as world lighting mods).

  • Each .world file only impacts their specific neighbourhood. They have no impact on any other areas. If you want, you can only replace 'Vupont' and it will not impact 'La Crête.' They will not impact any other world.

  • BG 01 = La Crête (formerly Crestline Promenade)
    BG 02 = Lagon Port (formerly Llama Lagoon)
    BG 03 = Vupont (formerly Bridgeview)

  • This does not include a world map override and will not impact any world map overrides you have. The map image is just a static artwork. This mod changes the actual gameplay world for your existing saves and new saves.

  • This does not include any tray files/builds, and it will not automatically replace any lots or sims.

  • You can avoid a lot of issues by starting from "load game" , and load the area in build mode first, before live mode. This helps 'refresh' the zones.

  • You may get a last exception error the first time you load an area that says "could not slot object". This is expected, so please don't report it. This will only happen the first time you load each area. It just means the game was trying to reload an interaction using an object that is no longer there. (usually an art easel or a grill).

  • 🏴‍☠️compatible

Sometimes game updates / patches reset the world files. All you have to do is reinstall them again after the update.

Please DM me on Patreon if you have any questions or issues. I'm happy to help.

You can also dm me on Tumblr, but I might not see it right away.

You can also leave comments. But I may not see it right away or at all because I get so many notifications everyday, and comments are harder to keep track of.

Thank you for enjoying my work! Your support means everything to me.

Have fun! ♡

So the buy food mod is updated for the new world for subscribers but free users have to wait?

LIJOUE · April 30, 2026

No? Sorry idk if you misunderstood or if I'm misunderstanding you. The post with the updated BuyFood from April 16 should be free, is it not visible for you? In the post I mentioned that I will be updating it in stages because it impacts so many of my mods. Free subscribers don't have access to Vieuxcrest yet because I just shared it yesterday and it's in early access. Sorry if something was confusing.

Hey girl. Are you planning on updating the Italia mod? I'm kinda hesitant giving anything new a shot if older mods arent properly maintained

? I'm not sure I know what you mean. Italia is still perfectly playable. The only issues I'm aware of are related to my BuyFood mod which I just made a post about a few days ago to say I'm working on updating. Other than that, the only issues I know about are small things like icons not showing up. I would like to optimize the small details but right now my priorities are to fix the things that are nonfunctional, so the BuyFood mods and the Main Menu override. Please let me know if there's something else you noticed that's non-functional. Please keep in mind, I'm only one person. Also just in case you missed it. If you think the Italia world is not working, I mentioned in the instructions that the base game patch updates will periodically reset the world files. This happened to me literally yesterday. All you have to do is replace the world files again with the modded replacements. Hope that helps!
