Profiles
A profile contains a set of variables used by the Addressables build scripts. These variables define information such as where to save build artifacts and where to load data at runtime. You can add custom profile variables to use in your own build scripts.
Open the Profiles window (menu: Window > Asset Management > Addressables > Profiles) to edit profile values and create new profiles.

You can set up different profiles for the different phases or tasks in your development process. For example, you could create one profile to use while developing your project, one to use for testing, and one to use for final publishing or release. Setting up the profiles in advance and swapping between them is much less error prone than editing the values individually when you move to a different phase or perform a different task.
Right-click a profile name to set it as the active profile, rename the profile, or delete it.
Addressables defines five profile variables by default:
- Local: defines two path variables for local content:
- Local.BuildPath: where to build the files containing assets you want to install locally with your application. By default, this path is inside your Project Library folder.
- Local.LoadPath: where to load assets installed locally with your application. By default, this path is in the StreamingAssets folder. Addressables automatically includes local content built to the default location in StreamingAssets when you build a Player (but not from other locations).
- Remote: defines two path variables for remote content:
- Remote.BuildPath: where to build the files containing assets you plan to distribute remotely.
- Remote.LoadPath: the URL from which to download remote content and catalogs.
- BuildTarget: the name of the build target, such as Android or StandaloneWindows64
You can choose the following pre-defined Bundle Locations for the Local and Remote path variables:
- Built-In: the path definitions for local content. The build system automatically includes content built with this setting in your Player builds. You should not change these path values.
- Editor Hosted: the path definitions to use with the Editor [Hosting service]. Depending on how you set up the hosting service, you might need to edit the load path to match the service URL.
- Cloud Content Delivery: the path definitions for the Unity Cloud Content Delivery (CCD) service. Requires creating a Unity Project ID in the Services section of your Project settings (or linking to an existing ID). You must also install the CCD Management SDK package. See Addressable Asset system with Cloud Content Delivery for information about setting up and using the Cloud Content Delivey Bundle Location option.
- Custom: Allows you to edit the values used for the build and load paths. See Profile variable syntax for information about setting a variable value using placeholders that Addressables evaluates at build-time and runtime.
Warning
In most cases, you should not change the local build or load paths from their default values. If you do, you must manually copy the local build artifacts from your custom build location to the project's StreamingAssets folder before making a Player build. Altering these paths also precludes building your Addressables as part of the Player build.
See Builds for more information about how Addressables uses profiles during content builds.
Tip
Using multiple profiles is most helpful when you distribute content for your application remotely. If you distribute all content as part of your application install, then the single, default profile might be the only profile you need.
Setting the active profile
The active profile determines the set of variables used when you run a build script.
To set the active profile, either:
- Open the Groups window (menu: Window > Asset Management > Addressables > Groups).
- Click the Profile menu in the toolbar.
- Choose the profile to make active.
Or:
- Open the Profiles window (menu: Window > Asset Management > Addressables > Profiles).
- Right- or cmd-click on a profile to open the context menu.
- Choose Set Active.
Note
Build scripts include the Play Mode Scripts that Addressables invokes when you enter Play mode in the Editor. Some Play Mode scripts use variables from the active profile to locate content. See Play Mode Scripts for more information.
Adding a new profile
To create a new profile, select Create > Profile. A new profile row appears in the table.
Every profile must define a value for every variable. When you create a new profile, Addressables copies all values from the currently selected profile.
Adding a new variable
You can add two kinds of variables to your profiles:
- A basic variable defines a single value
- A path pair defines a set of two path values; one for the build path and one for the load path
You can use basic variables as components of your path values (BuildTarget is an example of this) and you can use them in your own build scripts. Use path pair variables to set the Build & Local Paths setting of your Addressables [Groups] and remote catalog.
To add a new Profile variable, select either Variable or Build Load Path Variable from the Create menu. At the prompt, give the new variable a name and value, then click Save. Addressables adds the new variable to all profiles.
Right-click the variable name to rename or delete the variable.
Path Pairs
Path pairs define a matched set of BuildPath
and LoadPath
variables. When you create a path pair you can use the pair name to assign the path setting of an Addressable Group or remote catalog as a unit.
To create a path pair, select Create > Build Load Path Variables. At the prompt, give the path pair a prefix name and assign path strings to the individual fields.
A new path pair
The new path pair uses the Custom Bundle Location setting with your initial values. You can change to a different Bundle Location if needed.
Tip
You can "convert" two regular variables for the build and load paths into a path pair by renaming them in the Profile window. Set one to VariableName.BuildPath
and the other to VariableName.LoadPath
.

Default path values
The default values for the build and load paths are:
- Local build path:
[UnityEditor.EditorUserBuildSettings.activeBuildTarget]
- Local load path:
[UnityEngine.AddressableAssets.Addressables.BuildPath]/[BuildTarget]
- Remote build path:
ServerData/[BuildTarget]
- Remote load path:
http://localhost/[BuildTarget]
In most cases, you should not change the local path values. The Unity build system expects the AssetBundles and other files to exist in the default location. If you change the local paths, you must copy the files from the build path to the load path before making your player build. The load path must always be within the Unity StreamingAssets folder.
If you distribute content remotely, you must modify the the remote load path to reflect the URL at which you host your remote content. You can set the remote build path to any convenient location; the build system does not rely on the default value.
Profile variable syntax
All variables are of type "string". You can type in a fixed path or value. You can also use two syntax designations to derive the all or part of a variable's value from static properties or other variables:
- Square brackets [ ]: Addressables evaluates entries surrounded by square brackets at build time. The entries can be other profile variables (such as [BuildTarget]) or code variables (such as UnityEditor.EditorUserBuildSettings.activeBuildTarget). During a build, as it process your groups, Addressables evaluates the strings inside square brackets and writes the result into the catalog.
- Curly brackets { }: Addressables evaluates entries surrounded by curly brackets at runtime. You can use code variables of runtime classes (such as {UnityEngine.AddressableAssets.Addressables.RuntimePath}).
You can use static fields and properties inside the square and curly brackets. The names must be fully qualified and the types must be valid in context. For example, classes in the UnityEditor namespace can't be used at runtime.
The code variables used in the default Profile variable settings include:
- UnityEditor.EditorUserBuildSettings.activeBuildTarget
- UnityEngine.AddressableAssets.Addressables.BuildPath
- UnityEngine.AddressableAssets.Addressables.RuntimePath
As an example, suppose you have a load path of: {MyNamespace.MyClass.MyURL}/content/[BuildTarget]
set on a group that creates an AssetBundle called "trees.bundle". During the build, the catalog registers the load path for that bundle as {MyNamespace.MyClass.MyURL}/content/Android/trees.bundle
, evaluating [BuildTarget]
as "Android" and adding the AssetBundle name to the path. At runtime, as the catalog is processed, the Addressables system evaluates {MyNamespace.MyClass.MyURL}
to produce the final load path, http://myinternet.com/content/Android/trees.bundle
.
Note
Referencing a runtime variable in a Profile string does not prevent Unity from stripping that variable from your application’s runtime libraries during its build optimization phase (if nothing else in your code references the same variable). See Managed code stripping for more information on how to prevent a class or member from being stripped.
Specifying packing and loading paths
Once you set up the necessary variables in your profile, you can select the build and load paths for an asset group based on those specified variables.
To set your build and load paths:
- Select an Addressable Assets group from the Project window.
- In the group’s Inspector, under Content Packing & Loading > Build and Load Paths, select the desired path pair. If you choose the
<custom>
option, you can specify the build and load paths separately.
Notice that you do not enter the path directly, but rather select a variable representing the path defined in the Profiles window earlier. The Path Preview shows the current path, based on the active Profile. To edit a path directly in the Group settings Inspector, set Build & Load Paths to <custom>
and also set the individual Build or Load Path to <custom>
. The edited path applies to that group only.
Profile examples
Consider the following example, demonstrating the local development phase of your content.
Content with local and remote bundles stored locally for development.
While in development, you would have both your local and remote bundles using local paths, as seen below.
Paths set for local development.
In this instance, you can see that the local and remote paths are in fact local, which makes it unnecessary to set up a remote server just for local development.
Once the content is ready for production, you would move the remote bundles to a server, as the diagram below shows.
Content with the remote bundles moved to a server for production.
In this case, using profiles, you could change the remote load path for "Production" to that server. Without having to change your asset groups, you can change all of your remote bundles to actually become remote.
Paths set for hosting remote content
Important
- The Addressables system only copies data from Addressables.BuildPath to the StreamingAssets folder during a Player build -- it does not handle arbitrary paths specified through the LocalBuildPath or LocalLoadPath variables. If you build data to a different location or load data from a different location than the default, you must copy the data manually.
- Similarly, you must manually upload remote AssetBundles and associated catalog and hash files to your server so that they can be accessed at the URL defined by RemoteLoadPath.
