    If storage space is a concern, when choosing an installation location, you can select Options and deselect parts of the Engine that you will not need. For instance, you can disable any content under Target Platforms if you do not intend to develop for them individually to save some additional space.

Checking that Datasmith Entitlements Are Active

Starting with the release of Unreal Engine version 4.19, the delivery process for the Datasmith plugin has changed. If you have an “Active” Unreal Studio entitlement (see below), Datasmith can and will be installed alongside the Engine automatically.

In the left panel of the Epic Games Launcher, you should see the subscription status listed for Unreal Studio:

If you don't see the highlighted area listed, you may not have entitlements enabled for this account, so be sure to log in with an Unreal Studio-enabled account. If you need additional information about entitlements for Datasmith, see the Unreal Studio knowledge base.

Validating that Datasmith is Installed

  1. Once Unreal Engine 4 has been installed, you can click Installed Plugins under the Engine version to verify that the Unreal Datasmith plugin has been installed.
