Importing Datasmith Content into Unreal Engine

How to use Datasmith to bring files that you create in supported 3D design applications into Unreal Engine.

This page describes how to use Datasmith to import content from a supported 3D design application or file format into Unreal Engine.

Prerequisites

Before you can import content with Datasmith, you might have to enable some Unreal Engine plugins or install additional software.

Datasmith Plugins

To import content into Unreal Engine using Datasmith, your project must have the Datasmith Importer plugin enabled. If you don't enable the plugin, you won't see the Datasmith import options in Unreal Engine. Some supported file formats require additional plugins.

If you start your project from one of the Architecture or Automotive, Product Design, and Manufacturing templates, some or all of the Datasmith plugins are enabled by default.

Additional Software

To import some supported file formats, you must install additional software. The following file formats have specific software requirements:
