Uploading Assets to your package

After you create a package draft, you can add your Assets and upload them to this package draft. There are two ways to do this:

  • Open the Project containing the Assets you want to upload inside the Unity Editor.
  • Go to the Create new package page, navigate to the Package upload section, and click the Launch Unity button to launch Unity and open your Project.

To prevent confusion during upload and import for your users, make sure that the Assets you want to upload are inside a top-level folder with the same title as your submission. This folder contains all of the components for your Project:

Your Unity Project with the Assets inside a top-level folder
Your Unity Project with the Assets inside a top-level folder

Note: If your package contains audio or video files, you must upload samples of your media Assets in the Audio/Video section of your package draft’s Package Detail section.

To upload Assets to your package:

  1. Download the Asset Store Tools package from the Asset StoreA growing library of free and commercial assets created by Unity and members of the community. Offers a wide variety of assets, from textures, models and animations to whole project examples, tutorials and Editor extensions. More info

  2. Open the Unity Project containing the content you want to submit to the Asset Store and import the Asset Store Tools into it.
