Datasmith can only import content into a Project that has access to a special set of content and Plugins. We call this an Unreal Studio Project, because access to this set of content and Plugins is covered by your Unreal Studio entitlement.
This page describes two ways you can make an Unreal Studio Project to use with Datasmith:
- by creating a new one from a template that comes with Unreal Engine, and
- by converting an existing project that you've already created from a non-Unreal Studio template.
