You can try out this Experimental feature, but we do not recommend shipping projects with it.

Features are sometimes made available in an Experimental state so you can try them out, provide feedback, and see what we are planning. We do not recommend shipping projects with Experimental features. Please keep in mind that we do not guarantee backward compatibility for assets created at the experimental stage, the APIs for these features are subject to change, and we may remove entire Experimental features or specific functionality at our discretion.

Zen Store

An Overview of Zen Store.

Zen Store is an experimental feature that enables you to store cooked assets to a local storage server instead of loose files into the local filesystem. The storage server enables games to run on development kits without the need to deploy the game content. The storage server can be enabled by navigating to your C:\MyProject\Config\DefaultGame.ini file and implementing the following settings:

[Zen.AutoLaunch]
DataPath=%APPSETTINGSDIR%Zen/Data
LocalDataCachePathEnvOverride=UE-LocalDataCachePath
LocalDataCachePathEditorOverrideSetting=LocalDerivedDataCache
ExtraArgs=--http asio --gc-cache-duration-seconds 2937600 --gc-interval-seconds 21600

[/Script/UnrealEd.ProjectPackagingSettings]
bUseZenStore=true

The storage server makes it possible to read chunks over HTTP, by using the command:

-ZenStoreHost=[ip]

This enables games to run on development kits without the need to deploy the game content.
