Fab Window in Unreal Engine | Unreal Engine 5.4 Documentation

This page is not available in the language you have chosen. It will be displayed in English by default. If you would like to view it in a different language, you can try selecting another language.

When working in Unreal Engine, you can access Fab directly to acquire and download plugins and assets for your project, by using the Fab window. This works similarly to accessing Fab through your browser, but there are some differences.

Accessing Fab

To access Fab in Unreal Engine, navigate to the Window menu, and scroll down to Fab in the Get Content section.

Alternatively, you can open the Content Drawer, then click on the Fab button right next to the Add+ button.

Fab Plugin

The Fab window requires the Fab plugin, which is enabled by default in Unreal Engine. If you can't access the Fab window, navigate to Edit > Plugins, then search for and enable the Fab plugin.

Fab Products

The Fab window provides a way for you to find, view, and evaluate product listings, so that you can acquire these products for use in your projects in Unreal Engine. Product listings can be either free or priced. You can interact with listings both as product tiles in the Fab window, and by clicking the product tiles to view the full listing.

Product Tiles

Product tiles in the Fab window show you basic information about the associated product. This includes:

Name
Publisher
Rating
Price (or Free)
Whether the product is already saved in your library.

You can interact with listings directly in the Fab window using the product tiles.

Mousing over the product tile shows you the product type, and compatible file formats.
You can click the cart icon to add the product to your cart, and the wishlist icon to add it to your wishlist.
When you click to add a product to your cart, you must also select a license.

Product Preview

When you click a product tile in the Fab window, you are shown a preview of the full product.

The product preview shows basic information about the product, including:

Publisher
Name
Product type
Rating
Available license types and terms
Included file formats
Publish date
Age rating
AI usage and generation.

You can expand images to view them in full screen, and you can view certain products with 3D models in the Fab 3D Viewer.

You can also scroll down the preview to find a full description of the product, with all the relevant technical information for each supported file type.

Product Type Panel

You can use the product type panel on the left of the Fab window to view only specific types of products. You can expand each of the product types listed to show subtypes or tags, which provide a way for you to refine your list of viewed products. From there, you can use the filter menus to further limit the list of products you are shown in the Fab window. You can reset your product type filter by clicking All products at the top of the panel.

The Fab window provides a full list of products available to purchase (for priced products) or add to your library (for free products). It also provides a broad range of filtering and sorting options, available in the filter menu at the top of the product list. These are at the top of the Fab window in any view showing multiple products except the Discover view, where they are available beneath the featured products.

Each of the filter menu options provides a different way for you to refine your search for products in the Fab window. You can use as many filters as you like, and can clear them individually or all together using the filter tags at the top of the product list.
