Sims 4 Upload Mods Tutorial

Full tutorial on how to upload your own Mods & CC for The Sims 4 on the official Mods Hub!

It’s official! The Sims 4 Mod Hub with CurseForge is now live! Simmers can start downloading their favourite mods and custom content from the CurseForge website. Starting on December 6th, players will also be able to add mods and custom content directly into their games via the CurseForge app, too. For creators, you can start uploading your content right now! We’re going to walk you through the process of submitting your mods and custom content to the new Mod Hub!

Submitting to The Sims 4 Mod Hub

It’s very easy and straight forward to start hosting your content on The Sims 4 Mod Hub. On the main download page, choose Start Project to begin the process of submitting your creations. You’ll be taken to a submission page. We’ll break down this screen for you below:

CurseForge Downloads

The Basics

  • Select Game: Of course, you’ll want to select The Sims 4
  • Select a Category: Choose an option from the dropdown list that best suits your content. Are you uploading mods, builds, pets, Sims, etc?
  • Name: This is the title of your content. Be straight forward and avoid putting version numbers or other extra info here. Just what your content is called.
  • Summary: A quick description of what your content is. Again, be straight-forward and avoid info-dumping on The Sims 4 Mod Hub.
  • Description: This is where you can give any extra info about your content. Keep in mind that CurseForge does not allow direct links or redirects to any content outside of CurseForge so don’t put them in your descriptions. Descriptions are also required to be grammatically correct; no chat speak.

More Info

  • Allow Project Distribution: It is recommended you choose to allow this. Disabling this will exclude your content from CurseForge’s creator rewards program.
  • Project License: All Rights Reserved is probably going to be the license type most creators will want to select.
  • Primary Category: This is where you can sub-categorize your content on The Sims 4 Mod Hub. If you selected mods, select whether you’re uploading a pose/animation, a functional object, a scenario, etc. If you do not see your content listed here, try going back to Select a Category. You may not have selected the one that best fits your content.
  • Categories: If your content fits multiple subcategories, you can select any other categories your content falls under here.
  • Logo Image: Upload an image to represent your content. Your image must be 1:1 ratio (square) and at least 400×400 pixels. Images that do not show the content will be rejected, so no blank/placeholder images.
  • Allow Comments: Enable/Disable this as you see fit. We recommend having them enabled. It’s useful to see feedback from people using your content.
  • This Project is Experimental: If your content is still under development and exploring the limitations of the game, check this. If not, leave it unchecked.

Uploading Your Files to The Sims 4 Mod Hub

CurseForge: New Project

Fill in all the information listed above to start your project. Now it’s time to upload the files and other images to have it reviewed. Click the File button at the top of your project page and fill in all the necessary info.

  • Upload File: All content uploaded to CurseForge must be in .zip format. Make sure you zip up your package and ts4script files before uploading them.
  • Display Name: This is what you want to call the file.
  • Release Type: Most creators will want to choose Release but if your content is in an alpha or beta stage, select the one that applies to your content.
  • Changelog: This is where you’ll record all updates you’ve made to your content.
  • Supported Base Game Versions: Select which version of The Sims 4 base game your content is compatible with.
  • Supported Expansions/Game Packs/Stuff Packs: If your content requires a specific pack, indicate so here.
  • Related Projects: If your content is part of a collab with someone else, or if your content required another mod or piece of CC by someone else, you can indicate this here.

Submit all the above data to The Sims 4 Mod Hub to have it reviewed.

If you have extra images you’d like to include with your content, you can add more images to the project by clicking the Image button at the top of your project page. Extra images do not need to have a 1:1 aspect ratio like the main preview image.

Rejected! Why?

CurseForge sends a notification to you if they reject your content. The notification specifies the reason for the rejection. In addition to all the tips we’ve given in this article, there are additional content guidelines creators must follow when submitting projects to The Sims 4 Mod Hub. Most notably, all content uploaded to The Sims 4 Mod Hub must comply with the game’s T rating. This means no violence or explicit sexual content. Creators should also avoid uploading projects that reference real-world brands and public figures.
