Create and export asset packages
If you want to share scenesA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary, samples, tools, or other assets, you can export an asset packageA collection of files and data from Unity projects, or elements of projects, which are compressed and stored in one file, similar to Zip files, with the .unitypackage extension. Asset packages are a handy way of sharing and re-using Unity projects and collections of assets. More info
See in Glossary (.unitypackage format). You might want to create an asset package to copy several assets or an entire scene from one project to another. Another option is to create your own Unity package.
Follow these instructions to export an asset package.
Note: If your assets are high quality and other users might find them useful, refer to Publishing to the Asset Store for instructions to create a package draft and upload it to 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
See in Glossary.
To create and export an asset package:
Open the project you want to export assets from.
Go to the ProjectIn Unity, you use a project to design and develop a game. A project stores all of the files that are related to a game, such as the asset and Scene files. More info
See in Glossary window and select one or more items or folders. These items become the starting list for your export. You can also select theAssetsfolder as a way include all assets as your starting point.-
Choose AssetsAny media or data that can be used in your game or project. An asset may come from a file created outside of Unity, such as a 3D Model, an audio file or an image. You can also create some asset types in Unity, such as an Animator Controller, an Audio Mixer or a Render Texture. More info
See in Glossary > Export Package from the menu to open the Exporting package dialog.
Exporting package dialog In the dialog, select the assets you want to include in the package by clicking on the boxes.
Leave Include dependencies enabled to automatically select any assets used by the assets you already selected. Enabling Include dependencies also includes any scriptsA piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like. More info
See in Glossary that are directly required by the selected assets.-
Leave Include all scripts enabled to export all scripts from your project. If you disable Include all scripts but enable Include dependencies, Unity still exports the scripts that your selected items directly depend on. Unity doesn’t have a way to determine whether the scripts in your selection reference other scripts. Enabling Include all scripts reduces the likelihood of compilation errors when using the exported package in another project.
Tip: Selecting all items and enabling both checkboxes is a simple way of exporting the assets in a scene without manually locating them all.
Click Export to bring up the file explorer and choose where you want to store your package file.
Name and save the package.
Re-exporting asset packages
If you want to change the contents of an asset package and create a newer, updated version of your asset package, select the asset files you want in your package (both the unchanged ones and the new ones). Then follow the previous instructions to export the files.
Naming strategies
Rename your updated package using incremental names: for example, MyAssetPackageVer1, MyAssetPackageVer2. Unity recognizes it as an update, so you should use a naming convention that’s clear for you and anyone you share it with.
Warning: Don’t remove files from asset packages and then add different files with the same name. Unity uses unique IDs to track files, so it recognizes them as different and possibly conflicting files. In these cases, Unity displays a warning symbol when importing them. If you have removed a file and then decide to replace it, rename it something else, even if it is close to the original name.
